Recent research revealed that genetic variations affect the response of patient to treatment for lymphoblastic leukemia. Researchers believe that these genetic variations explain why some children do not respond to the treatment of this type of blood and bone marrow cancer although about 80 percent of children are cured.
Washington, Feb 27 : In a breakthrough discovery, scientists have found that a system of opposing genetic forces determines why mammals develop a single row of teeth, while sharks sport several.
The study suggests that carefully understanding the genetic program may prove helpful for scientists to re-grow missing teeth and prevent cleft palate, one of the most common birth defects.
Gene expression is the process by which information stored in genes is converted into proteins that make up the body''s structures, and carry its messages.
Washington, Feb 27 : Bringing bio-engineered organs a step closer to reality, scientists have described how a "scaffolding" material extracted from the groin area of mice could be used to grow stem cells from blood, fat, and bone marrow, which could further be used to "grow your own organs".
The advance, by researchers from Stanford and New York University Langone Medical Center, clears two major hurdles to bio-engineered replacement organs- a matrix on which stem cells can form a three-dimensional organ and transplant rejection.
Washington, Feb 27 : Long-term use of beta carotene and some other carotenoid-containing dietary supplements could raise the risk of lung cancer, says a new study.
According to the study by University of North Carolina at Chapel Hill researchers, certain people - especially smokers - who took dietary supplements containing these nutrients, were at higher risk of developing lung cancer than the general population.
London, Feb 27 : Healthy eating and exercise could reduce the risk of most common cancers by more than a third, says a study by the World Cancer Research Fund (WCRF).
The report also said that in developing countries like China and Brazil, such lifestyle practices, could cut cancer risk by almost a quarter.
These figures do not include smoking, which alone accounts for about a third of cancers.
London, Feb 27: Adding caffeine to sunscreens could boost protection against the most common form of skin cancer, claim scientists.
According to the study, conducted by a team from Harvard Medical School and Pfizer, caffeine has an effect on cells which can go on to cause non-melanoma skin cancers and found that the stimulant encourages the harmful cells to die.
The breakthrough study shows at caffeine helps eliminate human cells damaged by UV light, which can develop into cancer, by causing them to commit suicide, reports The Telegraph.
