Gingival overgrowth is a serious side effect that accompanies the use of amlodipine. Several conflicting theories have been proposed to explain the fibroblast's function in gingival overgrowth. To determine whether amlodipine alters the inflammatory responses, we investigated its effects on gingival fibroblast gene expression as compared with untreated cells. Fragments of gingival tissue of healthy volunteers (11 years old boy, 68 years old woman, and 20 years old men) were collected during operation. Gene expression of 29 genes was investigated in gingival fibroblast cell culture treated with amlodipine, compared with untreated cells. Among the studied genes, only 15 (CCL1, CCL2D, CCL5, CCL8, CXCL5, CXCL10, CCR1, CCR10, IL1A, IL1B, IL5, IL7, IL8, SPP1, and TNFSF10) were significantly deregulated. In particular, the most evident overexpressed genes in treated cells were CCR10 and IL1A. These results seem to indicate a possible role of amlodipine in the inflammatory response of treated human gingival fibroblasts.

Tumor necrosis factor receptor superfamily member 10 (TNFRSF10) is a death domaincontaining receptor for the apoptotic ligand TNFSF10, which involves multiple processes, including hepatocarcinogenesis and immune response against HBV infection. Several single nucleotide polymorphisms (SNPs) were identified as expression quantitative trait loci (eQTLs) for TNFRSF10. To assess the association of TNFRSF10 eQTL SNPs with the risk of hepatocellular carcinoma (HCC) and chronic HBV infection, we designed a case-control study that included 1,300 HBV-related HCC patients, 1,344 chronic HBV carriers, and 1,344 subjects with HBV natural clearance, and then genotyped two TNFRSF10 eQTL SNPs (rs79037040 and rs2055822). We found that rs79037040 GT/TT genotypes were associated with a decreased HCC risk (adjusted odds ratio [OR] = 0.83, 95% confidence intervals [CIs] = 0.71-0.97, P = 0.021) but an increased chronic HBV infection risk of borderline significance (adjusted OR = 1.14, 95% CIs = 0.98-1.33, P = 0.085). In contrast, the rs2055822 G allele was a risk factor for HCC (adjusted OR = 1.12, 95% CIs = 1.00-1.25, P = 0.041) but a protective factor for chronic HBV infection (adjusted OR = 0.89, 95% CIs = 0.80-0.99, P = 0.038). Furthermore, we observed a dose-dependent relationship between the number of alleles (rs79037040-T and rs2055822-A) and the risk of HCC and chronic HBV infection. In comparison with "0" alleles, having "1-4" alleles was significantly associated with decreased HCC risk and increased HBV infection risk. These findings suggest that eQTL SNPs for TNFRSF10 may be susceptibility markers for HCC and chronic HBV infection. (C) 2015 Wiley Periodicals, Inc.
