LGR5
LGR5(富含亮氨酸重復(fù)序列的G蛋白偶聯(lián)受體5)是Wnt信號(hào)通路的關(guān)鍵受體,又稱G蛋白偶聯(lián)受體49(GPR49),在腸道、毛囊等組織的干細(xì)胞中特異性表達(dá),被視為成體干細(xì)胞的標(biāo)志物。LGR5通過與R-spondin家族蛋白結(jié)合,增強(qiáng)β-連環(huán)蛋白的穩(wěn)定性,調(diào)控干細(xì)胞自我更新與組織再生。LGR5在結(jié)直腸癌、胃癌等惡性腫瘤中高表達(dá),其陽性細(xì)胞群體常表現(xiàn)出腫瘤干細(xì)胞特性,與化療耐藥、復(fù)發(fā)轉(zhuǎn)移密切相關(guān)。近年來針對(duì)LGR5的藥物開發(fā)聚焦于單克隆抗體和小分子抑制劑,其中LGR5-ADC(抗體藥物偶聯(lián)物)在臨床前研究中顯示出靶向清除腫瘤干細(xì)胞的潛力。基于LGR5陽性細(xì)胞的CAR-T療法也在探索中,但需克服靶向正常干細(xì)胞的脫靶風(fēng)險(xiǎn)。在再生醫(yī)學(xué)領(lǐng)域,調(diào)控LGR5信號(hào)通路為潰瘍性結(jié)腸炎、放射性腸損傷等疾病提供了新思路。

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.
