Prostate:转移性前列腺癌相关的P62能够抑制自噬流和促进上皮间质转化

2018-02-18 AlexYang MedSci原创

P62可以通过多种路径参与细胞自噬。P62在自噬体中与自噬体相关的LC3-II和泛素化蛋白聚合体互作从而吞噬聚合物,还可与HDAC6互作来抑制它的脱乙酰酶活性来维持乙酰化α-微管蛋白水平和微管的稳定性来增强自噬体转运,并且还可以调节自噬起始和细胞生存。最近,有研究人员在来源于前列腺癌病人的前列腺组织中进行了P62免疫组化染色,发现P62在患有前列腺腺癌(PCA)的病人中的水平要比那些患有良性前列腺

P62可以通过多种路径参与细胞自噬。P62在自噬体中与自噬体相关的LC3-II和泛素化蛋白聚合体互作从而吞噬聚合物,还可与HDAC6互作来抑制它的脱乙酰酶活性来维持乙酰化α-微管蛋白水平和微管的稳定性来增强自噬体转运,并且还可以调节自噬起始和细胞生存。

最近,有研究人员在来源于前列腺癌病人的前列腺组织中进行了P62免疫组化染色,发现P62在患有前列腺腺癌(PCA)的病人中的水平要比那些患有良性前列腺癌增生(BPH)的病人显著更高。高P62水平预示着高等级肿瘤和高密度的转移。研究人员还发现,P62能够增加HDAC6的水平和减少乙酰化α-微管蛋白水平及微管的稳定性。最后,高水平的P62除了能够损伤细胞自噬流外,还能够促进上皮-间质转化,且进一步导致增殖、迁移、前列腺癌细胞入侵能力的增强。

最后,研究人员指出,P62可通过维持P62的水平来促进PCA的转移,从而抑制细胞自噬和促进上皮-间质转化。
