Ths suggests that reduction of endogenous B catenncreases mortalty fee mce soon after AK.the survvng mce, serum creatnne ranges at 2 days right after folc acd have been sgnfcantlyhgher KsB cat mce thathat the controls.Accordngly, KsB cat kdneys exhbted more serious morphologcal njury, partcularly the outer strpe of out medulla regon, characterzed by reduction of brush border, tubular selleck cell depletoand cast formatothe lumen.Quanttatve assessment of kdney morphologcal njury betweecontrol and KsB cat groups at two days following folc acd njectos presented Fgure 4c.With each other, clear that reduction of endogenous B catenaggravates tubular lesons and acute kdney faure nduced by folc acd.Ablatoof B catenpromotes tubular cell apoptoss and Bax expressoTo check out the mechansm underlyng the cytoprotectve part of endogenous B catenAK, we more examned apoptotc cell death the kdneys of management and KsB cat mce immediately after folc acd njecton.As showFgure 5a, TUNEL stanng revealed consderable apoptoss the two cortcal and medullar regons of the kdneys control mce at 2 days right after folc acd admnstraton.
however, the frequency of apoptoss the KsB cat kdneys was sgnfcantlyhgher thathat the controls selelck kinase inhibitor beneath very same condtons.Quanttatve data oapoptotc cells both cortcal and medullar regons of manage and KsB cat mce are presented Fgure 5b.These effects recommend that tubule specfc reduction of B catenexacerbates kdney njury by promotng apoptoss.We additional examned renal expressoand dstrbutoof Bax, a professional apoptotc member of Bcl 2 famy, manage and KsB cat mce, snce a central player medatng mtochondral dysfunctoand cell apoptoss.24, 25 As showFgure five, c and d, Bax protewas markedly ncreased the kdneys of KsB cat mce at 2 days just after folc acd njecton, whecompared to your controls.mmunohstochemcal stanng also unveiled a substantal ncrease of Bax proterenal tubules the kdneys of KsB cat mce.Ablatoof endogenous B catenactvates multple professional apoptotc pathways To elucdate the upstream sgnalng tharesponsble for Bax nductoKsB cat mce, we even further examned renal expressoof p53, a tumor suppressor protethat promotes apoptoss by regulatng Bax expresson.

6, a and b, p53 protewas sgnfcantly upregulated the kdneys of KsB cat mce at two days soon after folc acd njecton, comparng wth the controls.These data propose that p53 upregulatocould be a potental upstream sgnalng that leads to renal Bax nductoKsB cat mce right after njury.Bax protes also subjected to regulatoby Akt medated phosphorylaton.27 Therefore, we also examned the phosphorylatostatus of renal Akt vvo.As showFgure 6c, tubule specfc reduction of B catensubstantally nhbted Akt phosphorylatoat Serne 473 the KsB cat mce, although total Akt abundance was unaltered.
