Cyclin D1 governs microRNA processing in breast cancer

Cyclin D1, a protein that helps push a replicating cell through the cell cycle, also mediates the processing and generation of mature microRNA (miRNA), according to new research from the Kimmel Cancer Center at Thomas Jefferson University published November 29 in Nature Communications. The research suggests that a protein strongly implicated in human cancer also governs the non-protein-coding genome. The non-coding genome, previously referred to as junk DNA, makes up most of the human genome, and unlike the coding genome, varies greatly between species.

NCI cancer centers logoAmong the research institutions NCI funds across the United States, it currently designates 68 as Cancer Centers. Largely based in research universities, these facilities are home to many of the NCI-supported scientists who conduct a wide range of intense, laboratory research into cancer’s origins and development. The Cancer Centers Program also focuses on trans-disciplinary research, including population science and clinical research. The centers’ research results are often at the forefront of studies in the cancer field.
