Inhibiting Ash-2 activity.

Inhibiting Ash-2 activity, the number of methyl tags reduced to the histone , which holds the DNA inaccessible and somehow extends the life of the animal by not less than 30 %. Conversely, the researchers found, blocking the expression of a protein called Rbr-2 taxed with removing the tag – a demethylase – shortened the worm’s lives span of about 15 to 25 %. Worms in which the expression of both proteins were blocked had slightly shortened life.

The gene with the pronounced effect, Ash-2 makes a protein as Methyltransferase – means it works with other proteins, a chemical a chemical days a methyl group represented by a component of a cell DNA packaging machines, Which is a histone known. The presence or absence of this variable affects whether the DNA to close as yarn on a spool or unfolded, so that the genes to be expressed is wound.. Avoid prolonged conflict and instability in the region along the border with Darfur in western Sudan has caused tens of thousands of rural Chadians to flee their homes in recent months.This research was supported supported by grants from Les Fonds National de la Science, Programme Microbiologique , and to the Royal Society .

The presence of of cheat codes weakening the the biofilm, contaminating its very survival by to decline is.. Germs have been known cooperate a plurality of paths a variety of ways , including the formation of a biofilm multicell structures. Fluorescens biofilms can be formed when individual cells manufactures a polymer holds cells together, do not the colonization of liquid surfaces. During the production of the polymer is of metabolically expensive to about individual cells, which biofilms Group is benefiting of the increased access to oxygen in that surface colonization providing. But, soon to develop deception types in that live in the biofilm however do not produce the polymer is.
