Implications for treatment of birth defects, wounds, cancer The genetic pathway that regulates the way cells align themselves relative to each other has been found to act as a "stop sign" that signals organisms when to halt cell growth, according to new research published by biologists at the Center for Regenerative and Developmental Biology in Tufts University's School of Arts and Sciences. The research sheds light on one of the primary challenges to developing new ways to induce...

(Ivanhoe Newswire)-- Yale researchers have discovered how megakaryocytes or giant blood cells that produce wound healing platelets grow 10 or more times bigger than other blood cells and how they may cause a form of leukemia. "A failure of these cells to grow might be an initial trigger for megakaryoblastic leukemias," Diane Krause, senior researcher for the Yale Cancer Center, professor of laboratory medicine, cell biology, and pathology and associate director of the Yale Stem Cell...

(Ivanhoe Newswire) — Researchers have discovered how a protein "master regulator" goes awry, leading to metastasis, the fatal step of cancer. The protein mTOR is a "master regulator" of human protein synthesis. It helps normal cells sense nutrients and control cell growth and metabolism. But in many forms of cancer, this process goes awry, and mTOR reprograms normal cells to aberrantly divide, invade and metastasize. In the human body, mTOR is a molecular sensor that helps cells...

mTOR shown to play key role in the process Even yeast understand austerity. A finely tuned system evolved early on to help cells survive in a world where good times come as fast as they go. The system, a molecular switch found in organisms from yeast to humans, involves a nutrient-sensing protein that turns growth on in times of plenty and shuts it off when times are lean. New work from the lab of Wenyi Wei, PhD, an investigator in the Department of Pathology at Beth Israel Deaconess...

CK1 protein in cancer cells identified as possible future therapeutic target Researchers from the NYU Cancer Institute, an NCI-designated cancer center at NYU Langone Medical Center, have identified a cell cycle-regulated mechanism behind the transformation of normal cells into cancerous cells. The study shows the significant role that protein networks can play in a cell leading to the development of cancer. The study results, published in the October 21 issue of the journal Molecular...

Researchers at IRB Barcelona discover a crucial mechanism controlling the segregation of genetic material from parent to daughter cells. A finely tuned process of degradation tightly regulates CenH3 protein levels to ensure the correct function of the cell division machinery in Drosophila. From bacteria to humans, all forms of life are based on the capacity of one cell to divide into two or more identical daughter cells. In doing so, cells have to produce a copy of their genetic material...

  University of Illinois researchers are giving a light answer to the heavy question of cell growth. Led by electrical and computer engineering professor Gabriel Popescu, the research team developed a new imaging method called spatial light interference microscopy (SLIM) that can measure cell mass using two beams of light. Described in the Proceedings of the National Academy of Science (PNAS), the SLIM technique offers new insight into the much-debated problem of whether cells grow...

When developing babies are growth restricted in the womb, they are typically born with heads that are large relative to their bodies. The growing brain is protected at the expense of other, less critical organs. Now, researchers reporting in the August 5th issue of Cell, a Cell Press publication, unearth new molecular evidence that explains just how the brain is spared. In studies of rapidly growing fruit fly larvae, they've traced this developmental phenomenon to the activity of a gene...

Five distinguished Baylor College of Medicine scientists will receive the annual Michael E. DeBakey, M.D., Excellence in Research Awards Tuesday. The scientists will present their research and receive their awards in a special program from 2 to 4 p.m. in Alkek N315. These awards recognize significant and outstanding research accomplishments by scientists at BCM. The recipients present their work during a seminar at which they receive Excellence in Research medallions. The awards also include...

UT Southwestern Medical Center researchers have discovered a protein that guides blood vessel development and eventually might lead to a treatment to keep cancer cells from spreading. The researchers showed in mice that the Ras interacting protein 1 (Rasip1) is so specific and central to so many cellular processes that without it new blood vessels simply cannot form, said Dr. Ondine Cleaver, assistant professor of molecular biology at UT Southwestern and senior author of the study in the...


Word of the Day
conjunto
  • A style of popular dance music originating along the border between Texas and Mexico, characterized by the use of accordion, drums, and 12-string bass guitar and traditionally based on polka, waltz, and bolero rhythms.
The word 'conjunto' comes through Spanish, from Latin coniūnctus, past participle of coniungere, to join together; see conjoin
