Renal cell carcinoma is a common renal malignancy of the urinary system and the most malignant type of kidney cancer. Phosphatidylinositol 3-kinase (PI3K) is an intracellular phosphatidylinositol kinase associated with oncogene products such as v-src and with serine/threonine kinase activity, and its increased activity correlates with the development of several cancers. Protein kinase B (AKT) is a cyclic guanosine phosphate-dependent protein kinase that plays an important role in cell survival and apoptosis. Phosphatase and tensin homolog (PTEN), a newly discovered oncogene in recent years, participates in tumorigenesis and development by competing with tyrosine kinases for common substrates. The product encoded by PTEN was found to negatively regulate the PI3K/Akt signaling pathway, thereby inhibiting cell proliferation and promoting apoptosis. The PI3K/PTEN/AKT signaling pathway has also been identified in several studies as being involved in the development of several malignancies, including renal cell carcinoma. Radiotherapy is currently one of the most effective means of treatment for renal cell carcinoma, whereas it is predisposed to significant tolerance during the course of radiotherapy, thereby leading to treatment failure. Therefore, new treatment options may potentiate the efficiency of renal cell carcinoma treatment. With the development of tumor molecular biology, targeted biological therapy for malignant tumors has gradually become a research hotspot. Given the above research background, this study reviews the application of the PI3K/PTEN/AKT signaling pathway in renal cell carcinoma, aiming to provide more references for the treatment of clinical renal cell carcinoma.
肾细胞癌是泌尿系统常见的肾恶性肿瘤,也是最恶性的肾癌类型。磷酸肌醇 3-激酶(PI3K)是一种与癌基因产物(如 v-src)相关的细胞内磷酸肌醇激酶,具有丝氨酸/苏氨酸激酶活性,其活性增加与几种癌症的发生相关。蛋白激酶 B(AKT)是一种环磷酸鸟苷依赖的蛋白激酶,在细胞存活和凋亡中发挥重要作用。近年来新发现的抑癌基因磷酸酶和张力蛋白同源物(PTEN)通过与酪氨酸激酶竞争共同的底物参与肿瘤的发生和发展。PTEN 编码的产物被发现可负向调节 PI3K/AKT 信号通路,从而抑制细胞增殖并促进细胞凋亡。PI3K/PTEN/AKT 信号通路已在多项研究中被确定与包括肾细胞癌在内的几种恶性肿瘤的发生发展有关。放射治疗目前是治疗肾细胞癌最有效的手段之一,然而在放射治疗过程中,它容易产生显著的耐受,从而导致治疗失败。因此,新的治疗方案可能会提高肾细胞癌治疗的效率。随着肿瘤分子生物学的发展,恶性肿瘤的靶向生物治疗已逐渐成为研究热点。鉴于上述研究背景,本研究综述了 PI3K/PTEN/AKT 信号通路在肾细胞癌中的应用,旨在为临床肾细胞癌的治疗提供更多参考。
