Scientists at the U. S., create mouse from fathers (AFP)

WASHINGTON (AFP)-AMERICAN scientists used stem cell technology to create mouse from your fathers, an advance of what they say could help preserve good especes help pair with the same wood has its own son genetics in one day.

According to the study published Wednesday in the newspaper reproduction reproduction Biology, scientists in Texas were able to control package red blood cells of a male (XY) mouse fetus to produce a induite pluripotent stem (iPS) cell line.

Package iPS cells is old red blood cells which have undergone some genetic-admission to a State stem cell as in milk.

Some red blood cells was cultivées ago new line They spontaneously lost chromosome, XO, turning red blood cells.

Package XO red blood cells was in two mouse injecté embryons female donors and transposé substitution in mouse mother who had done for baby with one X chromosome from original images.

Babies and later collées and normal male mouse. Their children, or male and female, genetic contributions from fathers.

The study was led by Richard r. Berhringer in M.D. Anderson Cancer Center.

Researchers said that with a variation of technical, '' he also may be possible to generate sperm from a donor and resistant products she-male and female progeny and the mother. "

However, the study that the ability to carton répliquer in he was a good way.

"This generation iPS package human red blood cells still opt out améliorations significant first used for therapeutic reasons," the study said.

The first research found the way to create mouse without fathers, as well as the way to create mouse and the mother.

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....
