CANCER CELLS: WHY DO CANCER CELLS GROW AND SPREAD? THE MECHANISMS OF CANCER METASTASIS IN ENGLISH: IT'S LIKE A CAR ACCELERATOR AND BRAKE LINING
MicroRNA and CANCER METASTASIS
The most lethal property of cancer cells is that they grow and spread from one location in the body to another. The cancer cell spreading is called metastasis. What makes cancer cells grow and why do cancer cells spread? Robert Weinberg and friends have spent a lifetime asking that question. It's the one trillion dollar question. People who unlock the secrets of cancer growth and metastasis(cancer cells spreading from one area to another) will have solved the greatest mystery in medicine and saved millions of lives.
Newsweek had a fascinating article about how cancer research is done and what works in cancer treatment or at least produce more practical results. And also how some things in science and medicine are sometimes decided in decidedly unscientific ways. According to the article, "there is no more common refrain among critics of how the war on cancer has been waged than that innovative ideas, ideas that might be grand slams but carry the risk of striking out, are rejected by the National Cancer Institute in favor of projects that promise singles...Part of the answer is that the infrastructure of cancer is to keep things moving along as they have been and to reward people doing safe research."

Robert Weinberg, a professor at M.I.T, has spent his life studying cancer. He discovered the first oncogene. Weinberg says oncogenes, which cause cell growth to speed up are analogous to a stuck car accelerator pedal. Tumor suppressor genes are analogous to a car's brake lining.
In this radio interview, Weinberg discusses how and why cancer cells spread as well as his latest research on the role of microRNA (RNA is similar to DNA) in the spread of cancer cells.
Weinberg Explains Cancer in Easy to Understand English
Lately, Weinberg and friends have published their findings that microRNA, small RNA molecules (RNA is similar to DNA but has a different component) are active in the control of metastasis. This is an easy to understand explanation by a top scientist who can also speak in plain English.
