Study shows how senescent cells can be an underlying cause of kidney damage

A study in mice by researchers at Georgetown Lombardi Comprehensive Cancer Center has found that stress and tissue damage initiated by angiotensin II, a molecule that is known to increase blood pressure and stiffening in the linings of blood vessels, leads to cellular senescence, a process by which a cell ages and permanently stops dividing but does not die.

Analysis of DNA tags could advance the understanding and treatment of many cancers

Analysis of DNA tags could advance the understanding and treatment of many cancers Cell-free DNA (cfDNA) shed into the blood was discovered in the late 1940s but with rapid advances in genomics and computational analytics in just the past few years, researchers at Georgetown Lombardi Comprehensive Cancer Center now believe that studying tags, or modifications to this type of DNA, may lead to a better understanding of how to assess, and possibly modulate, treatment approaches for cancer and other diseases. Their perspective, drawn from a review of studies to date, appears July 27 in Frontiers in Genetics. During cell death, which is a normal part of tissue regeneration, cfDNA is shed from tissue. The shed cfDNA can be isolated from a blood sample, thus providing a reading of cell death across the body in both normal and cancer cells without the need for taking invasive biopsy samples.
