Research found similar inflammatory cell distribution among asymptomatic tribals and duodenal ulcer patients, with increased cellular response but lower atrophy risk in tribal groups. The study suggests host factors may provide immunity to H pylori pathogenic effects.
Researchers used RNA interference to suppress MMP-2 expression in pancreatic cancer cells, leading to reduced adhesion and invasion without affecting cell proliferation and apoptosis. This finding suggests that inhibiting MMP-2 via RNA interference could be an effective therapeutic strategy for managing pancreatic tumors.
Researchers found that the omentum increases liver size by 50% after transplantation, suggesting its role in regenerating damaged liver tissue. The study also identified oval cells as the key players in this process, which may be a promising new treatment for liver disease.
Kepler will observe a broad region of the summer-time sky using a photometer to measure the brightness of stars. The mission aims to determine the number of Earth-like planets in the galaxy by watching for tiny flickers in starlight that could indicate a planet passing in front.
A study found that docosahexaenoic acid (DHA) can directly suppress arachidonic acid-induced proliferation of colon carcinoma cells, while also reducing viability. DHA supplementation may be a powerful tool to counteract AA- and PGE2-promoted colon cancer cell growth.
Aminoguanidine reduces pancreatic tumor growth, delays metastasis appearance, and extends mouse survival. The compound's mechanism involves inhibiting nitric oxide synthase, anti-angiogenic effects, and reduced antioxidant enzyme expression.
