Researchers spot genes tied Puberty, body fat Girls (HealthDay)

SUNDAY, Nov 21 HealthDay News)--Scientists have tuotevalikoimasi 30 genes that control the timing of Puberty in women. They believe also, many of these genes, the weight of the body, also have the option, or fat metabolism role.

The international team of researchers to analyze the genome-wide association studies (32), which includes more than 87,000 women from Australia, Europe and the United States. Time of exportation because of errors or perform replication studies almost 15 000 women to another group.

Already known to the two genes play an active role in the timing of Puberty in order to supplement the Group recognizes 30 new genes and other genes suggestive evidence of 10.

Newly discovered gene contains four previously body mass index (clinical measure ewight), three of which play an active role in the metabolism of the three, which is the role of hormone regulation report, which is designed to be published in the upcoming issue of the journal Nature Genetics.

"For us, the investigation found genes hormone regulation, cell development and other biological pathways associated with the average age of menarche the mechanisms of [the first menstruation onset], indicating that the timing of Puberty will be directed to complex biological processes in the region," a top author Dr. Joanne Murabito, Boston University School of Medicine, Associate Professor of medicine at the University, said in a press release.

"Multiple menarche genes is attached to the body weight and in other studies propose some women may have a genetic susceptibility to obesity, weight gain and early Puberty," he added. "It is important to understand that these genetic factors can modify lifestyle changes. In order to reduce or prevent childhood obesity should in turn help the girls at the beginning of efforts to reduce the onset of Puberty. "

The US National Institute of children's health and human development is about Puberty.

Protein folding via charge zippers

Jan. 18, 2013 — Membrane proteins are the "molecular machines" in biological cell envelopes. They control diverse processes, such as the transport of molecules across the lipid membrane, signal transduction, and photosynthesis. Their shape, i.e. folding of the molecules, plays a decisive role in the formation of, e.g., pores in the cell membrane. In the journal Cell, researchers of Karlsruhe Institute of Technology and the University of Cagliari are now reporting a novel charge zipper principle used by proteins to form functional units. "It is fascinating to see the elegant basic principles that are used by nature to construct molecular assemblies," explains Anne Ulrich, Director of the KIT Institute for Biological Interfaces. "A charge zipper between the charged side chains is an entirely unexpected mechanism used by membrane proteins to neutralize their charges such that they can be immersed into hydrophobic cell membranes....
