Effect of inhibiting ACAT-1 expression on the growth and metastasis of Lewis lung carcinoma.

Accumulating evidence suggests that acetyl-CoA acetryltransferase 1 (ACAT-1) may mediate tumor development and metastasis. However, the specific function served by ACAT-1 in lung cancer is not well understood. Therefore, the present study initially verified that ACAT-1 was overexpressed in Lewis lung carcinoma (LLC) tissues compared with non-LLC mice and that this overexpression promoted the proliferation, invasion and metastasis of these LLC samples.

Metformin induces apoptosis via a mitochondria-mediated pathway in human breast cancer cells .

Breast cancer is the most commonly occurring cancer and second leading cause of mortality in women. Metformin is a widely prescribed anti-hyperglycemic drug, which is emerging as a potential cancer preventative and treatment agent.

SRPX2 promotes cell migration and invasion via FAK dependent pathway in pancreatic cancer.

Sushi repeat-containing protein, X-linked 2, abbreviated as SRPX2, is a candidate downstream target protein for E2A-HLF and involved in disorders of language cortex and cognition. Recent studies have demonstrated that elevated SRPX2 exhibits crucial roles in gastric cancer, however, underlying clinical significance and biological function of SRPX2 in pancreatic ductal adenocarcinoma (PDAC), remains unclear. Data from Oncomine database showed that higher SRPX2 expression is more commonly observed in PDAC compared with normal pancreatic duct, similar results were also found in 12 matched PDAC tissue samples, 7 PDAC cell lines and a tissue microarray containing 81 PDAC specimens as demonstrated by real-time quantitative PCR and immunohistochemistry, respectively.

[Research progress of HGF/MET signaling pathway in EGFR-TKI resistance in non-small cell lung cancer].

Lung cancer is one of the most common malignant tumors of the world, and non-small cell lung cancer (NSCLC) makes up about 80%. The hepatocyte growth factor (HGF)/mesenchymal-epithelial transition factor (MET) signal pathway has pleiotropic effects on many biological processes. However, aberrant HGF/MET signal pathway activation has been observed in many tumor types, and promotes cellular proliferation and metastasis via growth factor receptors and other oncogenic receptor pathways.
