RNF43

RNF43(環(huán)指蛋白43)是一種位于細(xì)胞膜表面的E3泛素連接酶,在調(diào)控Wnt信號(hào)通路中發(fā)揮關(guān)鍵作用。RNF43通過(guò)標(biāo)記細(xì)胞膜上的Frizzled受體進(jìn)行泛素化降解,從而抑制Wnt信號(hào)過(guò)度激活,維持細(xì)胞增殖與分化的平衡。RNF43基因突變常見于結(jié)直腸癌、子宮內(nèi)膜癌及胰腺導(dǎo)管腺癌,尤其在微衛(wèi)星不穩(wěn)定型腫瘤中高頻出現(xiàn),其功能缺失會(huì)導(dǎo)致Wnt/β-catenin通路持續(xù)活化,促進(jìn)腫瘤發(fā)生。近年來(lái)針對(duì)RNF43突變腫瘤的治療策略取得進(jìn)展,如Wnt抑制劑LGK974(PRI-724)已在臨床試驗(yàn)中顯示對(duì)攜帶RNF43失活突變的胰腺癌患者具有潛在療效?;贑RISPR技術(shù)修復(fù)RNF43功能或聯(lián)合PARP抑制劑的新型療法也在探索中,為相關(guān)惡性腫瘤提供了精準(zhǔn)治療方向。

CSB-EP019892HU

(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.

RNF43 Antibody (CSB-PA019892LA01HU)

驗(yàn)證數(shù)據(jù)

CSB-PA019892LA01HU

IHC image of CSB-PA019892LA01HU diluted at 1:600 and staining in paraffin-embedded human lung cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
