Like normal cells, cancer cells require amino acids for growth, maintenance, and cell signaling, and L-type amino acid transporters (LATs) are the delivery vehicles that supply them. Metastatic, castration-resistant prostate cancer (CRPC) cells are highly dependent on LATs to deliver the amino acid leucine that the cells need for growth and proliferation, according to a study published September 19 in the Journal of the National Cancer Institute. To investigate the function of LATs in...

UCD Conway researchers have characterized epigenetic signature changes in prostate cells under conditions of low oxygen levels that may lead to tumor development. The results of the study published this month in the scientific journal, Human Molecular Genetics may provide important targets for the early detection and manipulation of prostate cancer.Chronic hypoxia, or low tissue oxygen levels, is a natural feature of the aging prostate either due to declining blood flow to the area or local...

Distinctive patterns of genes turned off "“ or left on "“ in healthy versus cancerous cells could enable early screening for many common cancers and maybe help avoid them, Medical College of Georgia scientists say.Researchers are comparing chemical alterations, called DNA methylation, in the body's basic building block in healthy colon, breast, brain and lymphatic cells and their cancerous counterpart to find telltale patterns that could one day be detected in the blood, urine or...

Most investigations into cancer have focused on chemical signals, but a new research study provides rare insight into how mechanical force can regulate cellular behavior. The study uncovers a link between tissue tension and tumor formation, suggesting that the stiffness of a tissue can influence molecular signals that promote the malignant behavior of tumor cells. The findings, published in the September issue of Cancer Cell, provide exciting new insight into the mechanisms that link the...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
