PLK1

PLK1(Polo样激酶1)是调控细胞分裂的关键蛋白,属于丝氨酸/苏氨酸激酶家族。该蛋白通过磷酸化下游靶点驱动有丝分裂进程,确保染色体精准分离和胞质分裂完成。研究发现,PLK1在多种恶性肿瘤中异常高表达,其活性失控会导致基因组不稳定性,促进肿瘤增殖与转移,尤其在乳腺癌、肺癌和结直肠癌中与预后不良相关。针对这一靶点,全球已开发出BI 2536、Volasertib等小分子抑制剂,其中Volasertib联合化疗在急性髓系白血病II期试验中显示出生存期延长,但因心脏毒性未获FDA批准。近年来研究者尝试通过联合用药策略降低毒副作用,同时探索PLK1与PARP抑制剂在DNA损伤修复中的协同效应,为实体瘤治疗开辟新方向。我国正大天晴等企业也在推进同类药物的临床试验。

Immunohistochemistry of paraffin-embedded human colon cancer using CSB-PA018193LA01HU at dilution of 1:100

CSB-PA018193LA01HU

Immunofluorescence staining of A549 cells with CSB-PA018193LA01HU at 1:133, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
