Site-directed mutagenesis is an essential technique for investigating the mechanisms of gene regulation on a molecular level, as well as for exploring post-translational modifications and functional structure at the protein level. Polymerase chain reaction combining in vitro synthesis of oligonucleotide primers allows for site-directed mutation to be performed with ease. However, site-directed ... more
Gene mutation plays an important role in molecular biological studies. A highly efficient one-step polymerase chain reaction-based mutagenesis technique for site-directed mutagenesis was developed in this study. One complementary pair of primers was designed that contained the desired mutations in the middle of the primers. The amplification products of mutation were amplified using a ... more
Bone desensitization after mechanical loading is essential for bone to adapt to its mechanical environment. However, the desensitization mechanism is unknown. Previous studies suggest that G protein-coupled receptors (GPCRs), including P2Y and parathyroid hormone receptors, play important roles in osteoblast mechanobiology. Thus, for the present research, we examined the role of G protein- ... more
Phosphorylation is an important part of post-translational modifications of proteins, and is essential for many biological activities. Phosphorylation and dephosphorylation can regulate signal transduction, gene expression, and cell cycle regulation in many cellular processes. Phosphorylation is extremely important for both basic research and drug discovery to rapidly and correctly identify ... more
We evaluated the influence of the vascular endothelial growth factor (VEGF) -C936T polymorphism on prognosis of hepatocellular carcinoma (HCC), cirrhosis, and hepatitis C virus (HCV) infection. Serum VEGF and alpha-fetoprotein (AFP) levels were determined and used to characterize sensitivity and specificity. A total of 285 subjects were studied: 68 HCC, 118 cirrhosis, 43 HCV, and 56 healthy ... more
The A1298C polymorphism of the methylenetetrahydrofolate reductase (MTHFR) gene has been reported to be associated with hepatocellular carcinoma (HCC), but there are conflicting results from previous studies. The present study aimed to investigate the association between this polymorphism and the risk of HCC using a meta-analysis of the published studies. Published literature ... more
Numerous studies have evaluated the association between the X-ray repair complementing defective repair in Chinese hamster cells 3 (XRCC3) T241M polymorphism and hepatocellular carcinoma (HCC) risk. However, the results of such investigations have proved inconsistent. Therefore, we performed a meta-analysis of the association between this polymorphism and HCC risk in the Chinese ... more
The association between the HLA-DP single nucleotide polymorphisms (SNPs) rs3077 and rs9277535 and hepatocellular carcinoma (HCC) has been reported, but results have been inconclusive and controversial. Therefore, to investigate the relationship between these HLA-DP SNPs and HCC susceptibility, a meta-analysis of studies published before January 2014 was carried out ... more
Osteopontin (OPN) plays an important role in the metastasis and recurrence of tumors after resection of hepatocellular carcinoma (HCC). In this study, the down-regulation effect on OPN expression in HCC cells of RNA interference (RNAi) molecules designed to target different segments of OPN was investigated to identify a more effective site for OPN knockdown. Specific small interfering ... more
KRAS, also known as V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog, acts as an intracellular signal transducer. The oncogenic KRAS mutation is an essential step in the development of many types of human cancers, including hepatocellular carcinoma. Here we aimed to investigate the relationship between KRAS rs712 polymorphisms and hepatocellular carcinoma ... more
