Downregulated expression of hsa_circ_0037515 and hsa_circ_0037516 as novel biomarkers for non-small cell lung cancer.

Circular RNAs (circRNAs) represent a class of endogenous non-coding RNAs. Recently, it has been reported that circRNAs might serve as novel potential biomarkers for the diagnosis of cancer, including non-small cell lung cancer (NSCLC). Mutations in the ATP binding cassette subfamily A member 3 () have been increasingly associated with lung disease; however, roles for circRNAs at the locus have not been identified.

Genetic variant of miR-4293 rs12220909 is associated with susceptibility to non-small cell lung cancer in a Chinese Han population.

Non-small cell lung cancer is one of the most common cancers and the leading cause of cancer death worldwide. Genetic variants in regulatory regions of some miRNAs might be involved in non-small cell lung cancer susceptibility and survival. rs12220909 (G/C) genetic polymorphism in miR-4293 has been shown to be associated with decreased risk of esophageal squamous cell carcinoma.

miR-449b rs10061133 and miR-4293 rs12220909 polymorphisms are associated with decreased esophageal squamous cell carcinoma in a Chinese population.

Esophageal cancer is one of the most aggressive cancers in the world, 70% of which are from China and esophageal squamous cell carcinoma (ESCC) is the major histopathological form (>90%). The single nucleotide polymorphisms (SNPs) in mature sequence of microRNA (miRNA) (mmSNPs) could cause the alteration of microRNA expression and contribute to the susceptibility of cancers. To evaluate the association between mmSNPs and ESCC, a case-control study including 773 patients with ESCC and 882 gender- and age-matched controls was carried out to investigate the association of five mmSNPs (miR-449b rs10061133, miR-4293 rs12220909, miR-608 rs4919510, miR-627 rs2620381, and miR-646 rs6513497) with ESCC susceptibility.

Sulfotransferase SULT1A1 Arg213His polymorphism with cancer risk: a meta-analysis of 53 case-control studies.

Background: The SULT1A1 Arg213His (rs9282861) polymorphism is reported to be associated with many kinds of cancer risk. However, the findings are conflicting. For better understanding this SNP site and cancer risk, we summarized available data and performed this meta-analysis.
