STAT3

STAT3,即信號轉(zhuǎn)導和轉(zhuǎn)錄激活因子3,別名包括急性調(diào)節(jié)蛋白、信號轉(zhuǎn)導激活因子、亞油酸誘導蛋白等。STAT3是一種轉(zhuǎn)錄因子,廣泛存在于多種細胞類型中,由人體細胞自身的基因編碼。其作用機制主要是在細胞接收到外部信號,如細胞因子、生長因子或其他刺激后,被激活的酪氨酸激酶磷酸化,形成二聚體,隨后轉(zhuǎn)移到細胞核內(nèi)調(diào)控特定基因的表達。STAT3的激活涉及JAK/STAT、IL-6/STAT3等信號通路,其中Janus激酶(JAK)首先被激活并磷酸化STAT3,導致其同源二聚化和核內(nèi)轉(zhuǎn)位。STAT3在生物學上的意義非常廣泛,它參與調(diào)節(jié)細胞的多種生理過程,包括細胞增殖、分化、遷移、凋亡以及免疫應(yīng)答等。STAT3的激活對于維持細胞穩(wěn)態(tài)和適應(yīng)外界變化至關(guān)重要。此外,STAT3在多種疾病的發(fā)生發(fā)展中也扮演著關(guān)鍵角色,尤其是在腫瘤發(fā)展中,STAT3的持續(xù)激活與腫瘤細胞的增殖、存活、血管生成和免疫逃逸等密切相關(guān)。因此,STAT3成為了癌癥治療中的一個重要靶點。在自身免疫性疾病、炎癥反應(yīng)和組織修復中,STAT3的調(diào)節(jié)作用同樣不容忽視,靶向STAT3的干預(yù)策略可能為這些疾病的治療提供新的途徑。

STAT3 Recombinant Monoclonal Antibody (CSB-RA546821A0HU)

驗證數(shù)據(jù)

CSB-RA546821A0HU

Overlay histogram showing Hela cells stained with CSB-RA546821A0HU (red line) at 1:50. The cells were fixed with 70% Ethylalcohol (18h) and then incubated in 10% normal goat serum to block non-specific protein-protein interactions followedby the antibody (1μg/1*106 cells) for 1 h at 4℃.The secondary antibody used was FITC-conjugated goat anti-rabbit IgG (H+L) at 1/200 dilution for 30min at 4℃. Control antibody (green line) was Rabbit IgG (1μg/1*106 cells) used under the same conditions. Acquisition of >10,000 events was performed.
