Association between the XRCC1 polymorphisms and clinical outcomes of advanced NSCLC treated with platinum-based chemotherapy: a meta-analysis based on the PRISMA statement.

Background: Base excision repair (BER) pathway is a DNA repair pathway that is important in carcinogenesis and in response to DNA-damaging chemotherapy. XRCC1 is one of important molecular markers for BER. So far, the role of XRCC1 polymorphisms with clinical outcomes of advanced NSCLC treated with platinum-based chemotherapy is inconclusive.

MicroRNA-19 triggers epithelial-mesenchymal transition of lung cancer cells accompanied by growth inhibition.

The miR-19 family (miR-19a and miR-19b-1) are key oncogenic components of the miR-17-92 cluster. Overexpression of miR-19 is strongly associated with cancer invasion and metastasis, and poor prognosis of cancer patients. However, the underlying mechanisms remain largely unknown.

Triosephosphate isomerase and peroxiredoxin 6, two novel serum markers for human lung squamous cell carcinoma.

There is currently substantial interest in the identification of human tumor antigens for the diagnosis and immunotherapy of cancer. In our previous study, secretion character and up-regulation of triosephosphate isomerase were observed in lung squamous cell carcinoma, and autoantibodies against triosephosphate isomerase and peroxiredoxin 6 were detected in the sera from over 25% of patients, but in none of the healthy controls. In this study, peroxiredoxin 6 was also found at higher levels in the sera of the patients.

Proteomic analysis of the stroma-related proteins in nasopharyngeal carcinoma and normal nasopharyngeal epithelial tissues.

The stroma surrounding cancer cell population is increasingly recognized as playing an important role in cancer proliferation, invasion, and metastasis. To identify the stromal proteins involved in nasopharyngeal carcinoma (NPC) carcinogenesis, differences in protein expression of the stroma from NPC and normal nasopharyngeal epithelium tissues (NNET) were assessed using a comparative proteomic approach combined with laser capture microdissection (LCM). LCM was performed to purify stromal cells from NPC and NNET, respectively.

Identificating 14-3-3 sigma as a lymph node metastasis-related protein in human lung squamous carcinoma.

In this study, we aim to screen metastasis-related proteins in human lung squamous carcinoma (LSC) using laser capture microdissection and a proteomic approach. Twenty two differential proteins were identified from pooled microdissected primary LSC and matched lymph node (LN) metastatic tissues. Expression of the differential protein 14-3-3 sigma was determined by Western blotting and immunohistochemistry.
