Ovarian cancer advances when genes are silenced

labspaces.net

There are many mechanisms that alter the activity of genes -- direct changes to the DNA code like mutations and deletions, or changes that control when genes are switched on and off, called epigenetic means. Tumor-suppressor genes are often inactivated through epigenetics, which provides an opening for the cancerous growth of cells.

Ovarian cancer advances when genes are silenced

eurekalert.org — “Researchers at the Duke Cancer Institute have found evidence of epigenetics at work on a genome-wide scale in cases of ovarian cancer. One major biological signaling pathway in particular was found to contain many genes influenced by DNA methylation -- a mechanism for turning off genes -- in tumor cells.View full resource at eurekalert.org

Nanoparticle-based gene silencing system inhibits angiogenesis process in tumor growth

news-medical.net — “A protein associated with cancer progression when abundant inside of tumors also unexpectedly regulates the creation of new blood vessels that feed the tumor outside, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports in the August edition of Cancer Cell.View full resource at news-medical.net

MicroRNA linked to shut-down of DNA-repair genes

sciencedaily.com — “New research shows that microRNA can silence genes that protect against cancer-causing mutations. The study found that microRNA-155 can inhibit the activity of mismatch repair genes, which normally correct damage that occurs when the wrong bases are paired in DNA. Loss of these genes causes cancer-susceptibility syndromes and can contribute to colorectal, uterine, ovarian, and other cancers. It is the first evidence that deregulation of microRNAs can cause genomic instability, a characteristic oView full resource at sciencedaily.com
