Association betweenITGA2 C807T polymorphism and gastric cancer risk

AIM:To evaluate the impact of the ITGA2 gene polymorphism on gastric cancer risk.METHODS:A hospital-based case-control study was conducted,including 307 gastric cancer patients and 307 ageand gender-matched control subjects.The genotypes were identified by polymerase chain reaction-restriction fragment length polymorphism assay.RESULTS:The frequencies of the wild and variant genotypes in cases were significantly different from those of controls (P=0.019).Compared with individuals with the wild genotype CC,subjects with the variant genotypes (CT+ TT) had a significantly higher risk of gastric cancer (adjusted odds ratio=1.57,95% CI=1.13-2.17,P=0.007).In stratified analyses,the elevated gastric cancer risk was especially evident in older individuals aged>58 years,nonsmokers and rural subjects.Further analyses revealed that the variant genotypes were associated with poor tumor differentiation and adjacent organ invasion in the sub-analysis of gastric cancer patients.CONCLUSION:The ITGA2 gene C807T polymorphism may be associated with an increased risk of gastric cancer,differentiation and invasion of gastric cancer.

Compatibility with Fructus Ligustri Lucidi Effectively Mitigates Idiosyncratic Liver Injury of Epimedii Folium by Modulating NOD-like Receptor Family Pyrin Domain Containing 3 Inflammasome Activation

Background: Idiosyncratic drug-induced liver injury(IDILI) is a serious side effect of drugs, Epimedii Folium(EF) is unequivocally implicated in idiosyncratic liver injury onset, potentially due to its ability to perturb the NOD-like receptor family pyrin domain containing 3(NLRP3) inflammasome. Fructus Ligustri Lucidi(FLL), a frequently used medicinal combination with EF, has not yet been investigated for its ability to ameliorate EF-associated hepatotoxicity. Aims and Objectives: Study on the mechanism of compatibility of FLL to alleviate liver injury caused by EF. Materials and Methods: Western blot was used to determine the expression of related proteins, ELISA was used to detect the secretion of related inflammatory factors IL-1β, IL-18, IL-6 and TNF-α, liver injury indexes were detected and liver pathological tissue staining was used to evaluate the liver injury. Results: Our results demonstrated that EF exerted a particular augmenting effect on the stimulation of the NLRP3 inflammasome mediated by nigericin or ATP, whereas FLL suppressed the NLRP3 inflammasome stimulation. Furthermore, an equal EF to FLL ratio significantly reduced the stimulatory effects of EF. Moreover, EF has the potential to induce hepatic injury and augment pro-inflammatory cytokine synthesis in rats subjected to LPS. However, when combined with FLL, the detrimental effects of EF were mitigated. Conclusions: FLL possesses the capacity to attenuate EF-associated hepatotoxicity by suppressing EF-triggered NLRP3 inflammasome activation. Thus, FLL holds promise for improving the clinical safety profile of EF, shedding light on the potential of compatibility and detoxification theories in traditional Chinese medicine.
