Sinclair research group previously reported in the journal Nature the first genetic link between environmental stresses and longer life. Low salt low salt, heat or extreme calorie restriction, a yeast master longevity regulator called PNC1 stimulates Sir2 activity. This new work by Harvard student Dudley Lamming argued that PNC1 the whole SIR2 family of genes regulated, suggesting that a man could PNC1 gene to protect against diseases of aging such as cancer, heart disease and diabetes.In advanced biliary tract cancer.. Referring publishes articles A team of scientists in World Journal of Gastroenterology. A research team of Germany studies EGFR and HER2 expression into biopsy samples of 124 patients diagnoses with enhanced BTC zwischen 1997 and 2004. Five micron sections were examined of paraffin-embedded tissue of standard, FDA approved immunohistochemistry. Tumor to notes of 2+ or 3+ for HER2 expression on immunochemistry have been additional test HER2 gene amplification by fluorescent in situ hybridization . In the advanced 34/124 , gallbladder cancer, 9 percent) intrahepatic BTC and 43 of had a extra hepatic and perihilar BTC. EGFR expression to a subset of a subset of 56 samples. EGFR expression was missing in 22/56 tumor and 3+ in 9 is obtained. HER2 expression of had following: Note 0 73 /124 and score 3+ 4/124 (3, HER2 genetic amplification was 6/124 available, which contributed to of amplification of 5 percent.

Epidermal growth factor receptor and human epidermal growth factor receptor 2 involved in carcinogenesis of many tumors. Therapeutic molecules targeted EGFR and HER2 were successfully used for the treatment of colorectal, lung, head or neck cancer, inter alia. Is not known if EGFR and HER2 advanced advanced bile duct cancers and can therefore act as therapeutic targets in the these cancers.
