Epidermal growth factor receptor (EGFR) is overexpressed in a variety of human malignancies, including pancreatic cancer, breast cancer, colon cancer, and non-small cell lung cancer. Overexpression of EGFR is a predictive marker of therapeutic response and several lines of evidence suggest that EGFR is an excellent target for tumor therapy. ...

The conventional approach to identifying the defective gene in a family with an inherited disease is to find the disease locus through family studies. However, the rapid development and decreasing cost of next generation sequencing facilitates a more direct approach. Here, we report the identification of a frameshift mutation in ...

Cyclooxygenase-2-derived prostaglandin E2 (PGE2) contributes to excitotoxic and ischemic neuronal cell death by engaging neuronal PGE2 type 1 receptors (EP1R). Our previous studies have shown that EP1R signaling resulted in disturbances of intracellular Ca(2+) homeostasis and suppression of the pro-survival protein kinase AKT. The aim of this study was to ...
