A gene's first 'kiss' sets off that affair known as puberty

... disorder that inhibits puberty's onset. To better understand what role GPR54 plays in the initiation of puberty, as well as learn about KiSS-1, which in earlier rodent studies had been identified as a molecule that activates a signal receptor of GPR54, the researchers looked to the nonhuman primate, the only a...

Scientists ID molecular 'switch' in liver that triggers harmful effects of saturated and trans fats

... Dana-Farber. "It offers the opportunity to try to understand what makes these fatty acids so deleterious, and what we need to avoid." Moreover, it is possible that in the future, drug therapy might be used to "turn down" the mechanism, decreasing cholesterol levels and heart disease risk, explained Spiegelman...

...ells or killer cells," Kappes said. His goal is to understand how T cells specialize to do different jobs. Commitment to the helper or killer lineages correlates precisely with the restriction of the T-cell receptor toward either class I or class II major histocompatibility complex (MHC) molecules. Most helper...
