LGR5

LGR5(富含亮氨酸重复序列的G蛋白偶联受体5)是Wnt信号通路的关键受体,又称G蛋白偶联受体49(GPR49),在肠道、毛囊等组织的干细胞中特异性表达,被视为成体干细胞的标志物。LGR5通过与R-spondin家族蛋白结合,增强β-连环蛋白的稳定性,调控干细胞自我更新与组织再生。LGR5在结直肠癌、胃癌等恶性肿瘤中高表达,其阳性细胞群体常表现出肿瘤干细胞特性,与化疗耐药、复发转移密切相关。近年来针对LGR5的药物开发聚焦于单克隆抗体和小分子抑制剂,其中LGR5-ADC(抗体药物偶联物)在临床前研究中显示出靶向清除肿瘤干细胞的潜力。基于LGR5阳性细胞的CAR-T疗法也在探索中,但需克服靶向正常干细胞的脱靶风险。在再生医学领域,调控LGR5信号通路为溃疡性结肠炎、放射性肠损伤等疾病提供了新思路。

CSB-RA262034A0HU

Overlay histogram showing HepG2 cells stained with CSB-RA262034A0HU (red line) at 1:50. The cells were fixed in 4% formaldehyde (15min) and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min 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.
