The results indicated that patients with GN and MetS were significantly older, and had more early gastric cancer and more colorectal neoplasms (CRN). Further, the presence of GN and MetS were significant independent risk factors associated with the prevalence of CRN. The frequency of CRN in patients with GN and MetS was 1.96 times greater than that in patients without GN or MetS. Multivariate logistic regression analysis of components

of MetS in GN patients showed that the presence of any two components of MetS in GN patients was a significant independent risk factor associated with the prevalence of CRN and that the OR for CRN increased according to the number of components of MetS in GN patients. What is BGB324 manufacturer the basis of the association of MetS with gastric and colorectal neoplasms? Several components of MetS, such as central obesity, dislipidemia, diabetes mellitus and insulin resistance have been linked to CRN.18 The chronic inflammation associated with MetS may be an important etiologic factor for colorectal neoplasms, since adipose tissue in patients with MetS is known to produce inflammatory cytokines that may play a role in colorectal carcinogenesis.19 The relationship

of MetS and GN is weaker, but as stated above, there are several studies that link obesity and gastric cancer.9 According to these results, the authors made a strong recommendation of screening Idasanutlin ic50 for synchronous CRN in patients with GN and MetS. This supports the conclusions of other investigators20,21 who also believe that patients with gastric adenomas or gastric cancer should have a screening colonoscopy as part of their pre-treatment plan. Another conclusion of this study is the intervention possibility in prevention of both gastric and colorectal neoplasms when addressing the very difficult

problem of treating MetS. Older and male subjects are at increased risk of both gastric and colorectal neoplasm and these risk factors cannot be reduced. However, each country should be committed to try and correct individual components of MetS, since there is evidence that the risk of associated gastric and colorectal cancer increases with the number of components of MetS. If the results of this single referral tertiary Korean center study are reproduced by other learn more Eastern centers, there should probably be a change in screening strategy for CRN in Eastern countries. Since the bulk of data concerning synchronous gastric and colorectal neoplasms comes from Eastern countries, related to their high gastric cancer prevalence and their increasing colorectal cancer prevalence, these conclusions may not be applied to Western populations. However, the heads-up data concerning the relationship of MetS and colorectal cancer should not be lost in Western countries, namely in the USA, where the incidence of MetS is over 20% of the adult population.

0; 18.1–83.7 ng/mL vs 57.6; 28.7–107 ng/mL, P = 0.001). In the younger, but not in the older children, the selleck chemicals llc serum

NGAL level correlated with their age, r = 0.334, P = 0.001. In children with inflammatory bowel disease, serum NGAL level was higher (108; 37.3–245 ng/mL) than in healthy (42.0; 18.1–107 ng/mL) and allergic, noninflammatory bowel disease children (49.3; 19.3–107 ng/mL), P = 0.001. Serum NGAL levels in Crohn’s disease and ulcerative colitis children did not correlate with age, gender, disease activity, and indices of the inflammation. Serum NAGL levels are highly elevated in Crohn’s disease and ulcerative colitis in children compared to the healthy control group. Systematic studies are needed to explain the role of this protein in the inflammatory bowel disease.

“Chronic infection with hepatitis B virus (HBV) is strongly associated with hepatocellular carcinoma (HCC), and the viral HBx protein plays a crucial role in the pathogenesis of liver tumors. Because the protooncogene learn more pituitary tumor–transforming gene 1 (PTTG1) is overexpressed in HCC, we investigated the regulation of this protein by HBx. We analyzed PTTG1 expression levels in liver biopsies from patients chronically infected with HBV, presenting different disease stages, and from HBx transgenic mice. PTTG1 was undetectable in biopsies from chronic hepatitis B patients or from normal mouse livers. In contrast, hyperplastic livers from transgenic mice and biopsies from patients

with cirrhosis, presented PTTG1 expression which was found mainly in HBx-expressing hepatocytes. PTTG1 staining was further increased in HCC specimens. Experiments in vitro revealed that HBx induced a marked accumulation of PTTG1 protein without affecting its messenger RNA levels. HBx expression promoted the inhibition of PTTG1 ubiquitination, which in turn impaired its degradation by the proteasome. Glutathione S-transferase pull-down and co-immunoprecipitation experiments demonstrated that the interaction between PTTG1 and the Skp1–Cul1–F-box ubiquitin ligase complex (SCF) was partially disrupted, possibly through a mechanism involving protein–protein interactions of HBx with check details PTTG1 and/or SCF. Furthermore, confocal analysis revealed that HBx colocalized with PTTG1 and Cul1. We propose that HBx promotes an abnormal accumulation of PTTG1, which may provide new insights into the molecular mechanisms of HBV-related pathogenesis of progressive liver disease leading to HCC development. (HEPATOLOGY 2010;51:777–787.) Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide.1 Chronic infection with hepatitis B virus (HBV) is the main causal factor for HCC.1 A growing body of evidence suggests that HBV may have a direct oncogenic capacity and that expression of virally encoded proteins, in particular the HBV X protein (HBx), promotes cell growth and tumor development.

Concerns regarding a need for immunosuppression will be affected by lineage biology. Nonimmunogenic stem/progenitors can acquire immunogenicity with

maturation that potentially can be managed by use of stellate cells, known to produce immunomodulatory signals. Liver cell therapies should also use grafting methods that optimize liver engraftment and prevent cell loss to ectopic sites as occurs in vascular route delivery, especially for stem/progenitors.62 The idea that cancers are transformed stem/progenitor cells originated with the pioneering work of Van Potter in the 1960s, who proposed that hepatomas contain cells undergoing “blocked ontogeny.”63 This idea was further elucidated for all types of cancers by Barry Pierce and

Stewart Sell,64 who clarified that many functions thought to be related to cancer (e.g., AFP expression) are normal functions of an expanded stem/progenitor cell population and selleck chemicals that identification of key distinctions must involve comparison of cancer cells to their normal stem cell counterpart.61, 65 Indeed, normal stem/progenitor cells are strikingly similar to tumor cells in morphology, gene expression, SRT1720 manufacturer and growth properties, and tumors can be identified as an expanded lineage stage.61, 66 The clinical use of stem cells may come with an increased risk of tumors depending on the donors (e.g., if there are undiagnosed tumor cells among the endogenous stem cells) and on the patient’s medical condition (e.g., severe immunosuppression). Strategies for cancer therapies will be revolutionized if revamped with lineage biology knowledge. Treatments with drugs selleckchem or radiation are known to affect later lineage stages preferentially. If a specific treatment also targets the lineage stage(s) containing malignantly transformed cells, then the treatment can be curative. If they fail to target that stage, there will be a lethal rebound effect: the treatment

kills cells in later lineage stages, mutes feedback loop signaling, and secondarily unhinges early lineage stages where malignant cells reside. Therefore, future cancer therapies should involve strategies identifying the lineage stage of the tumor and whether the treatment targets that stage or, alternatively, uses lineage mechanism regulation, such as feedback loop signals, to control the rate of growth of tumor cells. The intrahepatic maturational lineages begin within the stem cell compartments, located periportally, and progress through the midacinar region and ending near the central vein. The parenchymal cells, along with their mesenchymal cell partners, are governed by gradients of paracrine signals, including sets of soluble factors and insoluble extracellular matrix components, and by specific mechanical forces. Feedback loop signals regulate the stem/progenitors, controlling liver mass and tissue regeneration.

Our discovery that IL30 is a liver injury inhibitor bodes well with published results from IL27R−/− and EBI3−/− mice in a hepatitis model.23, 24 In RAD001 order a ConA model of hepatitis, lack of IL27 signaling (IL27R−/−) showed an exacerbated response, whereas EBI3−/− are protected from ConA-induced hepatitis when compared with wildtype mice. Based on our results, the reduced toxicity from ConA in EBI3−/− is perhaps due to increased IL30 resulting from a lack of EBI3 available to engage

and form IL27. Indeed, exogenous introduction of IL30 plasmids by way of gene therapy significantly reduced ConA-induced hepatotoxicity. Multiple lines of evidence from this study point to IL30 inhibition of liver toxicity independently

of IL27. First, IL30 inhibits liver toxicity and IFN-γ in EBI3−/− or WSX1−/− mice, and, second, reconstitution of either EBI3 or IL27 in EBI3−/− mice does not ameliorate liver toxicity. A previous study showed that IL30 binds to cytokines other than EBI3 to form an IL30/cytokine-like factor 1 complex (IL30/CLF), suggesting that IL30/CLF inhibits liver toxicity.33 The plausibility of this theory is questionable, as IL30/CLF needs WSX1 receptor to signal, whereas Selleckchem Saracatinib in our study IL30 can inhibit liver toxicity even in the absence of WSX1. Moreover, in our model IL12 mainly induces the transcription of IL30 and not EBI3. Of course, one possible argument is that the endogenous levels of EBI3 might be very high and induction of IL30 by IFN-γ results in the generation of IL27 that inhibits liver toxicity. This explanation is unlikely, as even in EBI3−/− and TCCR−/− mice, IL30 lowers hepatotoxicity. In summary, this study of IL30 reveals its novel function: inhibition of IL12/ConA-mediated liver injury, which occurs independently of both IL27 and WSX1 by preventing IFN-γ

expression in the liver and circulating IFN-γ in the serum. WSX1−/− mice were received from Genetech, with assistance from Frederic J. de Sauvage. selleckchem The authors thank Shiguo Zhu for performing some of the DNA administration and serum collection.

“Sirtuins are nicotinamide adenine dinucleotide oxidized form (NAD+)-dependent deacetylases and function in cellular metabolism, stress resistance, and aging. For sirtuin7 (SIRT7), a role in ribosomal gene transcription is proposed, but its function in cancer has been unclear. In this study we show that SIRT7 expression was up-regulated in a large cohort of human hepatocellular carcinoma (HCC) patients.

Cell lysates were analyzed by the dual luciferase assay (Promega) on a luminometer. To assess the activity of IKK, IKK was immunoprecipitated by IKKα antibody and protein G-Sepharose, and the assay was performed at 30°C for 1 hour in buffer

containing 20 mM Tris HCl, pH 7.5, 20 mM MgCl2, 2 mM dithiothreitol, 20 μM ATP, 2 μg GST-IκBα, and [γ-32P]ATP. The reaction was stopped by addition of Laemmli buffer and was resolved by 10% sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) followed by a transfer onto a membrane for imaging. Whole cell extracts were prepared as described.8 Equal amounts of selleck products the extract (20 μg) were separated by 8%-15% SDS-PAGE and the proteins were transferred to nitrocellulose membranes (Bio-Rad, Hercules, CA). MeCP2, type I collagen, and β-actin were detected by incubating with rabbit polyclonal anti-MeCP2 (1:1,000) (Abcam), anti-type I collagen (1:4,000), and anti-β-actin (1:5,000) primary antibodies (Santa Cruz Biotechnology) in TBS (100 mM Tris-HCl,

1.5 M NaCl, pH 7.4) with 5% nonfat milk overnight at 4°C followed by incubation with horseradish peroxidase-conjugated goat antirabbit secondary antibodies (1:4,000) (Sigma) at room temperature for 2 hours. The antigen-antibody complexes’ chemiluminescence was detected using the ECL detection kit (Pierce). Ivacaftor For assessing Pparγ epigenetic regulation, carrier ChIP was performed using Raji cells as the source of carrier chromatin. For learn more native ChIP, 20 μg of HSC chromatin was mixed with 80 μg of Raji cell chromatin. For crosslink ChIP, Raji cells (1.4 × 107 cells) were mixed with HSCs (0.2 × 106 cells) and fixed with 1% formaldehyde on the rotating platform for 5-10 minutes at room temperature followed by addition of glycine to a final concentration of 0.125 M. After lysis of the cells with SDS buffer (1% SDS, 10 mM EDTA, 50 mM Tris-HCl, pH 8.1) with protease inhibitors, the

lysates were sonicated and snap-frozen in aliquots. For chromatin IP, diluted samples were first precleared using protein G-agarose beads and then incubated with antibody against Ser2P RNApolyII, MeCP2, H3K27me2, H3K4me2, and H3Kacetylated (Abcam) at 1 μg/μL at 4°C overnight followed by precipitation with protein G-agarose beads. After elution of immunoprecipitated complex, crosslinking was reversed with 5 N NaCl and proteins digested with protease K. Extracted chromatin was subjected to real-time PCR using the primers flanking a segment within Pparγ promoter or exon as described.17 Ct values of the samples with nonimmune IgG were subtracted and compared to their respective input Ct values. The aqueous YGW extract (350 mg/mL in PBS) was applied to size exclusion chromatography using Super Prep Grade gel in XK 16/70 column (Amersham Pharmacia Biotech, Piscataway, NJ) and PBS as a mobile phase solvent.

The total duration of the moult cycle was measured as the interval between the two successive moults M1 and M2. Time between collection (i.e. assessment of the position in the moult cycle) and the first moult M1, relative to the total duration of the cycle, was used to

estimate the duration of the different phases of the moult cycle. Hence, we obtained a percentage of the cycle that was already completed per individual and average values were computed to obtain mean duration of each moult stage. The characterization of the selleck inhibitor moult cycle of G. pulex females followed the observation of a cyclic but constant and renewable phenomenon: the anatomical evolution of the dactylian claw and the dactylopodite shrinkage during a moult cycle. This has been previously described for other amphipods, Orchestia sp. and Niphargus virei (Charniaux-Cotton, 1957; Graf, 1968, 1986) and decapods (Drach, 1939; Drach & Tchernigovtzeff, 1967). For this purpose, the tip of the third right pereiopod was carefully cut off using fine INK128 forceps and gently placed in a drop of a Ringer solution

between a slide and a coverslip. Alternatively, the third left pereiopod and the right and left fourth pereiopods can be used for the dating of the same animal later in the moulting cycle. The claw of the pereiopod was observed under a Nikon Eclipse E600 microscope (×200 magnification). Pictures were obtained using a Nikon Digital Camera DXM1200F and software ACT-1 (Nikon, Tokyo, Japan). Pairs (amplexus) and unpaired males and

females were randomly sampled in the field (River Suzon) and placed into tubes filled with water. Collected animals were see more examined within 3 h. The moult stage was determined for all animals. Females were checked for embryos in the ventral pouch (resulting from a previous reproductive event). The type of moult of females (growth moult or egg-depositing moult) was also determined by checking the presence of maturing black ovaries, dorsally visible through the cuticle (vitellogenesis). We examined 138 pairs, 60 unpaired males and 52 unpaired females. Pairing status and behaviour according to female and male moult stages were analyzed with a χ2 test. Variation in size-assortative pairing was assessed overall using an analysis of covariance (ANCOVA) with the size of males as dependent variable and female size and moulting status as covariates. Pearson correlation tests were used to assess the magnitude of size-assortative pairing in each stage of the moulting cycle. All tests were performed using programs JMP© version 5 (SAS Institute, Cary, NC, USA). Females G. pulex with a size ranging from 1.68 to 2.58 (mean ± sd, 2.10 ± 0.19 mm) for the coxal plate (between 8.45 and 11.90 mm for the body length) have a 30-day moult cycle at 15°C (n = 44, mean 30.2 ± 3.6 days, range 24 to 40 days). It is subdivided into five periods accordingly (Fig.

2). Radioimmunity was applied to measure the plasma motilin level see more before and after ghrelin administration. 3). The c-Fos activation on the CNS and ENS through

intravenous injection of ghrelin was studied by the immunohistochemistry. Results: 1). Ghrelin showed an excitatory effect on gastrointestinal IMC. This effect was inhibited by atropine, L-arginine, ondansetron or (D-Lys3)GHRP-6, but not by propranolol and phentolamine. 2). The plasma motilin level in different phases of IMC of the normal rats had cyclical fluctuation with the lowest level in phase I, and the highest level in phase III. After injection of ghrelin, the cyclical fluctuation was not affected, and the motilin selleck chemicals level had little difference in each corresponding phase compared with that before ghrelin administration. 3). In the CNS, the c-Fos expression of several nuclei such as the arcuate nucleus, paraventricular nucleus, and so on, was increased by injection of ghrelin. And the c-Fos expression of the duodenum, jejunum, and proximate colon was also activated by ghrelin. Conclusion: Ghrelin appears to play an important role in regulating of intestinal motility. Its excitatory effect relies on the cholinergic pathway

and is closely related to the NOS-NO or 5-HT pathway. Ghrelin receptor GHS-R regulates its activity. The excitatory effects of ghrelin on the intestinal IMC don’t have relationship with plasma motilin level. Intravenous administration of ghrelin could regulate the intestinal motility through the ENS or CNS. Key Word(s): 1. selleck kinase inhibitor ghrelin; 2.

Organization (WHO) estimates that Chagas Disease (Ch D) affects 16 to18 million people worldwide. It is considered endemic in America. Argentina has 2,5 million infected people and 10 million people are exposed to infection. The cardiac affection is the most frequent and has been studied extensively. Gastrointestinal compromise is present in less than 11% and most affected organs are esophagus and colon. The impact of colon affection in our country is unknown. Objectives: 1. Estimate the prevalence of Ch D in chronic constipation (CC) patients. 2. Characterize the sample according to systemic compromise, place of origin, radiologic findings and presence or absence of Rectoanal Inhibitory Reflex (RAIR). Methods: We reviewed medical records of adult patients ≥18 years old who were referred for chronic constipation. Patients with positive serology for Ch D (ELISA, IFI) were included; other reasons for chronic constipation were exclusion criteria.

However, the level of hepatomegaly and hepatic

triglyceride accumulation was similar in ethanol-fed L-SIRT6, M-SIRT6 and d-SIRT6 KO mice compared with WT mice. Copanlisib mw The hepatic gene expression level of the proinflammatory cytokines TNF-alpha and interleukin (IL)-1 beta was similar in all groups of mice after chronic plus binge ethanol feeding. On the other hand, the expression level of the hepatoprotective cytokine IL-6 was higher in ethanol-fed L-SIRT6 KO mice and may protect these mice against alcoholic liver injury. Furthermore, the hepatic gene expression of the macrophage marker F4/80 was increased in ethanol-fed M-SIRT6 and d-SIRT6 KO mice compared with WT mice, suggesting that SIRT6 may regulate click here Kupf-fer cell functions. In conclusion, our findings indicate that SIRT6 in both hepatocytes and myeloid cells plays an important role in

promoting hepatocellular damage induced by chronic plus binge ethanol feeding independently of liver steatosis and likely through modulation of inflammatory components. Disclosures: The following people have nothing to disclose: Adeline Bertola, Ming-Jiang Xu, Chuxia Deng, Bin Gao Background: Tweak and its receptor, fibroblast growth factor-inducible 14 (Fn14, a TNF receptor superfamily member) function as growth factors for bipotent liver progenitor cells. Accumulation of Fn14-positive progenitors occurs in severe acute alcoholic steatohepatitis and correlates with acute mortality in humans. This study examined whether Fn 14 learn more deletion

is beneficial in an acute ethanol (EtOH) induced steatohepatitis model in mice. Methods: Adult C57BL/6 (WT, n=16) or FN14 KO (n=16) male mice were treated with High Fat Lieber de Carli diet (HF), HF+ 2% EtOH Lieber deCarli diet (EtOH), HF + CCl4 (1 μl/g body weight i.p. twice per week), or HF+EtOH+CCl4 for 2 weeks, and sacrificed 72 h after the last CCl4 injection (n=4/group). Livers were analyzed for injury, fibrosis, progenitors, and inflammatory cytokines using qRT-PCR, biochemical assays, and immunohistochemistry. Results: Compared to each of the respective WT control groups, WT mice treated with HF+ETOH+CCl4 had significantly higher hepatic expression of Fn14 mRNAand protein, and developed more severe steatohepatitis and bridging fibrosis, as evidenced by H&E and Sirius red staining, induction of cytokines (TNFα, IL6 and IL4 mRNAs), up-regulation of myofibroblast markers (α-SMA, Desmin mRNAand protein), and increased collagen content quantified by hydroxyproline assay. The progenitor response (as assessed by changes in mRNA and protein levels of α fetoprotein, Sox9, CD24 and Lgr5) paralleled the severity of steatohepatitis in WT mice. In Fn14 KO mice, elevation of Fn14 did not occur, steatohepatitis severity was reduced, and all the inflammatory and fibrosis responses were inhibited (each p < 0.05 vs WT mice). Progenitor accumulation was also dramatically attenuated (>50% reduction; p<0.05).

The cluster fragments are denatured, annealed with a sequencing primer and subjected to DNA synthesis with four differentially reversible labeled fluorescent nucleotides that have their 3′-end chemical termination to ensure that only a single base is extended. see more After a single base is incorporated into the DNA strand, the terminator nucleotide is detected via its labeled fluorescent dye by the CCD camera. Then, the labeled fluorescent dye and 3′-end chemical terminations are removed and the next DNA synthesis cycle

is repeated. The Genome Analyzer IIx can obtain 30–100 nucleotide read lengths and data output per paired-end run from 1–3 Gb.[16-18] Moreover, Illumina released a HiSeq sequencer series which enabled higher throughput and a desktop MiSeq sequencer type which could sequence more rapidly in 2013. THE ABI SOLID sequencer was introduced in October 2007. SOLiD is an abbreviation for “sequencing by oligo ligation BAY 73-4506 chemical structure and detection”. It uses a unique sequencing method catalyzed by DNA ligase. The universal P1 adaptor-linked DNA fragments are attached to magnetic beads. Emulsion PCR is conducted in microreactors containing the reagents of the PCR reaction. The magnetic beads are covalently attached to the surface of a specially treated glass slide that is placed into a fluidic cassette within the sequencer. The universal sequence primers

hybridize to the P1 adapter within the library template.

The set of four fluorescent-labeled di-base 8-mer probes are annealed to the sequencing primer and library template. Identification of the nucleotide sequence by the 8-mer probe is achieved by interrogating every first and second base in each ligation reaction. When there is a matching of the 8-mer probe to the library template adjacent to the universal primer of the 3′-end, DNA ligase seals the phosphate backbone. After the ligation, the probe is enzymatically removed together with the last three bases attaching the linkage between base 5 and 6. Then, the same probe hybridizing process is conducted and the sequence data of each library template can be obtained at five nucleotide selleckchem intervals. Following a series of ligation cycles, the library template is reset with five rounds of universal primers complementary to the n to n-4 position for a multistep round of ligation cycles. Through the primer reset process, each base is interrogated in two independent ligation reactions by two different primers and the nucleotide sequence is defined by this repetition. The ABI SOLiD 2.0 platform, produced in 2008, can obtain data output from 3–10 Gb per run.[16-18] HOWEVER, MUCH IMPROVED the NGS systems have already become, the competition in technology development is intensifying. The demand for low cost, high speed and highly accurate systems has spurred development beyond third-generation NGS systems (Table 1).

Wild-type (WT) and GNMT-KO mice were fed a standard diet (Teklad irradiated mouse diet 2014; Harlan, Madison, WI) and housed in a temperature-controlled animal facility with 12-hour light/dark cycles. At 1.5 months buy PLX-4720 of age, GNMT-KO (n = 20) and WT (n = 5) mice were treated for 6 weeks with NAM (50 μM dissolved in drinking water, which was replaced weekly) (Sigma-Aldrich) before sacrifice. For control groups, we used WT (n = 15) and GNMT-KO mice (n = 10) of the same age. At the time of sacrifice, livers were

rapidly split into several pieces; some were snap-frozen for subsequent RNA or protein extraction, and others were formalin-fixed for histological and immunohistochemical analysis. Serum samples were also collected for determination of alanine aminotransferase and aspartate aminotransferase activity. Animals were treated humanely, and all procedures were in

compliance with our institutions’ guidelines for the use of laboratory animals. Sections from formalin-fixed liver tissue were stained with hematoxylin-eosin or with Sirius Red for collagen visualization. For α-smooth muscle actin (α-SMA) immunostaining and apoptosis detection, frozen liver tissue sections were fixed with 4% paraformaldehyde for 15 minutes at room temperature, followed by treatment with 3% hydrogen peroxide in methanol for 10 minutes. The sections were then incubated with 150 mM sodium citrate Adriamycin mw for 2 minutes followed by washes in phosphate-buffered saline. For α-SMA immunolabeling, anti-α-SMA Cy3-conjugated antibody (Sigma) was applied overnight at 4°C. For apoptosis detection, fluorescein isothiocyanate-conjugated terminal selleckchem deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) enzyme was applied overnight at 4°C (in situ cell

death detection kit, Roche). Washing in ultrapure H2O and then in phosphate-buffered saline terminated the reaction. Nuclei were then labeled with Hoechst, and the cover slips were mounted in Citifluor mounting medium. Total RNA was isolated using the RNeasy Mini Kit (Qiagen) including DNase treatment on column. Total RNA (1.5 μg) was retrotranscribed with Super Script III (Invitrogen) in the presence of random primers and oligodeoxythymidylic acid following the manufacturer’s instructions. Real-time polymerase chain reaction (PCR) was performed using the BioRad iCycler thermalcycler. Five microliters of a 1/20 dilution were used in each PCR reaction in a total reaction volume of 30 μL using iQ SYBR Green Super Mix (BioRad), and all reactions were performed in duplicate. PCR was performed with the primers described in Supporting Table 1. After checking specificity of the PCR products with the melting curve, cycle threshold values were extrapolated to a standard curve performed simultaneously with the samples and data were then normalized to glyceraldehyde 3-phosphate dehydrogenase (GAPDH) expression.
