'Guardian of the genome' protein found to underlie skin tanning

...e people's desire to spend time in the sun. The same process that causes POMC to produce alpha-MSH also leads to the production of b-endorphin, a protein that binds to the body's opiate receptors and may be associated with feelings of pleasure. "Even as p53 is causing skin to tan during sunlight exposu...

It's OK for men with high blood pressure to have a drink or two, new study finds

...nce alcohol can increase blood pressure, would the same be true for men who have high blood pressure? The new study, published in the January 2, 2007, issue of Annals of Internal Medicine, is based on data from the Health Professionals Follow-Up Study.

Type of stem cell found to reside in transplanted lungs

...the transplant donor and recipient were not of the same sex, nearly all the MSCs (about 97 percent) originated in the donor, indicating that they were present in the tissue since the time of transplantation. "We were able to isolate the cells derived from the donor as far as 11,5 years after transplantati...

How appetite-stimulating brain cells work overtime during fasting

...n likely also causes changes in temperature in the same way that UCP1 does in brown fat, Diano said. "It's possible that heat may act like a neurotransmitter of a sort," Diano said. Neurotransmitters are chemical messengers that relay signals to and from neurons. "Changes in temperature could have a s...

Hybrid molecule causes cancer cells to self-destruct

...arts of the hybrid independently would achieve the same result. But in these experiments, the cancer cells did not self-destruct. The researchers suspect this is because the hybrid molecules more easily penetrate the surface of the cell than the individual chemicals. Once the components are inside, the re...

McBride shows DNA detective work with paper-eating bacteria that 'glide'

Synthetic peptide targets latent papilloma virus infections

...otchan and his colleagues shows that HPV works the same way. The UC Berkeley team created a short peptide that binds to E2 in hopes that this synthetic peptide would prevent E2, and thus the viral plasmid, from successfully tethering to the chromosomes.
