Published studies have evaluated associations between the MDM2 SNP309T>G polymorphism and bladder cancer susceptibility. However, these generated inconsistent results. The aim of the present investigation was to quantify the strength of association between MDM2 SNP309T>G polymorphism and bladder cancer risk by conducting a meta-analysis. We searched PubMed and Embase for related studies that ha...

Emerging evidences from preclinical and clinical studies have shown that epidermal growth factor (EGF) has some effectiveness against endogenously arising carcinogenesis. Functional +61A>G polymorphism (rs4444903 A>G) in the promoter region of the EGF gene was observed to modulate EGF levels, thus affecting the susceptibility to gastrointestinal cancer; but individually published studies showed...

BACKGROUND Tumor necrosis factor-α (TNF-α) 308 G/A gene polymorphism has been reported to be associated with susceptibility to silicosis. However, the relevant study results are still inconsistent. OBJECTIVE AND METHODS A meta-analysis was performed in order to drive a more precise estimation of the relationship between TNF-α-308 G/A gene polymorphism and susceptibility to silicosis. Electron...

The relationship between vascular endothelial growth factor gene polymorphism and gastric cancer risk and its development, prognosis, and survival are still being debated. This meta-analysis was performed to assess these relationships. The association reports were identified from PubMed, Embase, Cochrane Library, and CBM-disc (China Biological Medicine Database), and eligible studies were inclu...

BACKGROUND The ICAM-1 +469 A/G polymorphism has been implicated in susceptibility to cancer, but the results were inconclusive. The present meta-analysis aimed to investigate the association between the ICAM-1 +469 A/G polymorphism and cancer risk. METHODS We searched PubMed, Embase to identify studies that evaluated the association between the ICAM-1 +469 A/G polymorphism and cancer risk. Da...

Global-genomic nucleotide excision repair (GG-NER) is the only pathway available to humans for removal, from the genome overall, of highly genotoxic helix-distorting DNA adducts generated by many environmental mutagens and certain chemotherapeutic agents, e.g., UV-induced 6-4 photoproducts (6-4PPs) and cyclobutane pyrimidine dimers (CPDs). The ataxia telangiectasia and rad-3-related kinase (ATR...

BACKGROUND The gene for the vascular endothelial growth factor (VEGF), which promotes angiogenesis and permeability, is polymorphic. The aim of the present study was to evaluate the relationship between +936C>T and +404C>G polymorphism of VEGF with risk of esophageal cancer in the Kashmiri population in India. MATERIALS AND METHODS 150 esophageal cancer patients and 150 unrelated healthy cont...

PURPOSE To explore whether the vascular endothelial growth factor (VEGF) +405 G/C polymorphism confers susceptibility to breast cancer (BC) by conducting a meta-analysis. METHODS Publications addressing the association between the VEGF +405 G/C polymorphism and BC risk were selected from the PubMed, Embase and Google Scholar databases. Data were extracted from studies by three independent rev...

The GTPase dynamin catalyzes membrane fission by forming a collar around the necks of clathrin-coated pits, but the specific structural interactions and conformational changes that drive this process remain a mystery. We present the GMPPCP-bound structures of the truncated human dynamin 1 helical polymer at 12.2 Å and a fusion protein, GG, linking human dynamin 1's catalytic G domain to its GTP...
