Possible colorectal cancer gene identified

Researchers have found that a recently discovered gene plays an essential role in mediating apoptosis, or cell death, in colorectal cancer cells. The gene, PUMA, or p53 up-regulated modulator of apoptosis, is controlled by p53 ? a tumor-suppressing gene that prevents normal cells from turning into life-threatening tumor cells. Previous research has determined that damage to p53 is fundamental to the development of a vast majority of cancers, and inactivation of the growth-controlling function of p53 is critical to the growth and spread of most cancers.

Teeth Grinder’s Lament ? ‘E’ May Wound Brain

Results of an animal study published in the journal Science raise the possibility that the use of the rave fave drug Ecstasy ? methylene-dioxymethamphetamine ? can damage brain cells. The same cells, in fact, that are destroyed by Parkinson?s disease.
“We don’t know if human beings develop the same effects we describe in monkeys and in baboons,” Dr. George Ricaurte, a Johns Hopkins neurologist, told Reuters. “The broader issue is, are there hundreds of cases of unexplained parkinsonism in MDMA users? We don’t know because we haven’t looked.”
The Reuters article also contains the following quotation, reproduced below only marginally out of context: “[A]s you might imagine, it is not easy to get a baboon to take an oral dose of a drug.”
