Background: Single nucleotide polymorphisms of C-reactive protein (CRP) have been shown to be related to circulating CRP level, risk and prognosis in cancer patients. However, accumulating evidence of rs1800947 involvement in risk of cancer is inconsistent. Thus, a meta-analysis was performed to obtain a more precise relationship.

Article Synopsis
  • The study aimed to identify and quantify EGFR gene mutations in lung cancer tissues, comparing the efficacy of a new real-time PCR method (ADx-EGFR kit) to traditional Sanger sequencing.
  • A total of 208 tumor samples were analyzed, with Sanger sequencing successfully identifying mutations in 11.2% of cases, while the ADx-EGFR method detected mutations in 19.2% of samples.
  • Results indicated that the ADx-EGFR real-time PCR method had a significantly higher success rate and mutation detection capability than Sanger sequencing, proving it to be a more effective clinical tool for lung cancer screening.

Objective: To investigate the correlation between the proteasome subunit PSMA7 expression in colorectal cancer and its role in liver metastasis.

Methods: To identify the PSMA7 protein expression in 62 primary site colorectal cancers, 34 lymph node metastatic sites and 13 liver metastatic sites by immunohistochemistry and clarify the correlation of its expression with the clinicopathological parameters.

Results: High expression of PSMA7 was detected in 38.

The proteasome subunit PSMA7 located on the 20q13 amplicon was found to be differentially expressed in colorectal cancer by semiquantitative RT-PCR. PSMA7 mRNA was overexpressed in 37.5% (12/32) colorectal cancer tissues while it was either of a low level or not expressed in matched normal mucosa.

Aim: Angiogenesis is an important step in the growth of solid malignant tumors. A number of angiogenic factors have been found such as transforming growth factor beta1 (TGF-beta1) and vascular endothelial growth factor (VEGF). However, the roles of TGF-beta1 and VEGF in gastrointestinal carcinogenesis are still unclear.
