Background: A host of studies have explored the potential connection between () G19A polymorphism and the risk of cancers, but the relationship between gastric cancer (GC) susceptibility and G19A polymorphism was not revealed before. The aim of this study was to investigate this relationship in Chinese Han population.
Methods: Thus, this case-control study with 380 GC cases and 465 controls was designed to unearth the link between G19A polymorphism and GC susceptibility. Genotyping was accomplished by a custom-made 48-Plex SNP scanTM kit. Relative gene expression was detected by real-time reverse transcription-polymerase chain reaction.
Results: G19A polymorphism was shown to relate with a decreased risk of GC. Subgroup analyses uncovered significant connections in the males, nondrinkers, and those at age <60 years. G19A polymorphism was also linked with tumor size and location and pathological type of GC. Last, gene expression in gastric tissues was considerably less than in control tissues.
Conclusion: This study shows that G19A polymorphism of gene is linked with a lower risk of GC in the tested Chinese Han individuals.

Background And Aims: There is a link between genetics with metabolic balance and adiposity homeostasis on metabolic syndrome (MetS). Polymorphism in adipokine genes such as leptin and adiponectin may play an important role in its development. This study aimed to determine the association of the individual and general components of MetS with genetic alterations in LEP (rs7799039 and rs2167270) and ADIPOQ (rs1501299 and rs2241766) genes in the Mexican population.

Background: Although the effect of the LEP G19A (rs2167270) polymorphism on cancers is assumed, the results of its influence have been contradictory. A meta-analysis was conducted to precisely verify the relationships between LEP G19A and the development of digestion-related cancers.
Methods: Investigators systematically searched the literature in PubMed, Embase, and Web of Science and used STATA software 14.

Background: A host of studies show Leptin (LEP) G19A polymorphism is correlated with the risk of various cancers, but the connection of this polymorphism with bladder cancer (BC) risk has not been reported.
Materials And Methods: This association was in explored in a case-control study involving 355 BC cases and 435 controls (all Chinese Han). Polymerase chain reaction-restriction fragment length polymorphism was conducted to genotype LEP G19A polymorphism.

Accumulating evidence has suggested that leptin (LEP) is very important for the development of cancer. Recently, a number of case-control studies about the relationship of the rs2167270 G > A (G19A) variants in the LEP gene with the risk of cancer have yielded inconsistent results. In this study, we have carried out a case-control study [1063 esophagogastric junction adenocarcinoma (EGJA) cases and 1677 controls] in a Chinese population.
