Molecular chatter makes for a ‘hot tumor’

A Ludwig Cancer Research study has deciphered a complex molecular conversation between cancer and immune cells that is key to orchestrating the successful invasion of tumors by T cells that kill cancer cells. “We show that two key chemokines, CCL5 and CXCL9, are universally implicated in T cell infiltration across all solid tumors,” said George Coukos, who directs the Lausanne […]

New study reveals an unexpected survival mechanism of a subset of cancer cells

Embedded at the ends of chromosomes are structures called telomeres, which in normal cells become shorter as cells divide. Progressive shortening triggers cell proliferation arrest or death. Cancer cells adopt different strategies to overcome this control mechanism that keeps track of the number of times that a cell has divided. One of these strategies is the alternative lengthening of telomeres […]

Take steps to prevent a stroke

(HealthDay)—Strokes are common but not inevitable. There are ways you can reduce your risk, starting with your blood pressure. Stroke is the fifth leading cause of death in the United States and the leading cause of permanent disability, said Dr. Gary Bernardini, neurology chair at New York-Presbyterian Hospital Queens. Most strokes occur when blood flow to the brain gets cut […]
