Researchers identify protein linked to tumor invasion
Metastasis occurs when cancer cells penetrate the boundaries of the tumor’s tissue and infiltrate the walls of blood vessels or lymph vessels, gaining a means of transport to other parts of the body –- far from the original tumor site –- where they can then grow anew. This process is unique to cancer cells and…

RNA technology thwarts HIV
RNA interference (RNAi) is a naturally occurring phenomenon by which cells guard themselves against viruses. The process involves post-transcriptional gene silencing in which specific RNA sequences get chopped into small pieces after binding to complementary short interfering RNAs (siRNA). These siRNAs can target either host mRNAs or viral genomic or messenger RNAs. As a consequence,…
