Overexpression of RASAL1 Indicates Poor Prognosis and Promotes Invasion of Ovarian Cancer.

RAS protein activator like-1 (RASAL1) exists in numerous human tissues and has been commonly demonstrated to act as a tumor suppressor in several cancers. This study aimed to identify the functional characteristics of RASAL1 in ovarian adenocarcinoma and a potential mechanism of action. We analyzed RASAL1 gene expression in ovarian adenocarcinoma samples and normal samples gained from the GEO and Oncomine databases respectively.

Association between the MTHFR A1298C polymorphism and risk of cancer: evidence from 265 case-control studies.

Many molecular, epidemiological studies have been performed to explore the association between MTHFR A1298C polymorphism and cancer risk. However, the results were inconsistent or even contradictory. Hence, we performed a meta-analysis to investigate the association between cancer risk and MTHFR A1298C (81,040 cases and 114,975 controls from 265 studies) polymorphism.
