RAS蛋白激活剂样2(RASAL 2)属于RAS GTP酶激活蛋白家族,在多种癌症中起重要作用,包括卵巢癌、鼻咽癌、恶性星形细胞瘤、肾细胞癌、膀胱癌、结直肠癌、肝癌、三阴性乳腺癌、肺腺癌和胰腺导管腺癌。传统上,RASAL 2被认为是一种肿瘤抑制因子,但最近的研究发现,它是特定类型癌症中的癌基因,如结直肠癌、肝癌、三阴性乳腺癌、三阴性/雌激素受体阴性乳腺癌。本文综述了RASAL 2在肿瘤中的最新研究进展,以期对临床实践有一定的指导意义。本文就RASAL 2在不同类型肿瘤细胞中的特异性功能及其作用机制(包括其对肿瘤细胞侵袭、转移和血管生成的抑制作用及其相反作用)进行了讨论,为肿瘤的研究和治疗提供了新的方向。RASAL 2与不同类型肿瘤的临床分期、组织学分级、预后和总生存期的关系不同。RASAL 2是一个潜在的预后因子,也是一个新的诊断和治疗靶点。
RAS protein activator like 2 (RASAL2) belongs to the RAS GTPase-activating protein family and plays an important role in several cancers, including ovarian cancer, nasopharyngeal carcinoma, malignant astrocytoma, renal cell carcinoma, bladder cancer, colorectal cancer, liver cancer, triple-negative breast cancer, lung adenocarcinoma, and pancreatic ductal adenocarcinoma. Traditionally, RASAL2 has been regarded as a tumor suppressor but recent studies have found that it is an oncogene in specific types of cancer, such as colorectal cancer, liver cancer, triple-negative breast cancer, triple-negative/estrogen receptor-negative breast cancer. In this review, we summarize the latest findings regarding RASAL2 in cancers, which may be important and useful in clinical practice. We discussed the specific functions and mechanisms of RASAL2 in different kinds of cancer cells (including its inhibition of invasion, metastasis and angiogenesis and its opposite effects), which may provide new directions for cancer research and treatments. RASAL2 exhibits different relationship with clinical cancer stage, histological grade, prognosis and overall survival in different kinds of tumor. RASAL2 is a potential prognostic factor and a new therapeutic target for diagnosis and treatment.
