Human old and feeble mechanism or having new explanation
It is reported ' The clothing dawn peak reporter of the reporter Liu ZhongKui) The latest " cell " magazine publishes newest scientific findings about SIR2 gene such as the intersection of the life of Harbin Industry University and Dr., contract researcher Liu BeiDong of academy of sciences,et al. - -" the segregation of protein polymer of cell and polarise the mechanism with actin of cell and is correlated with ". Researchers have found a brand-new biological course in yeast cells, old and feeble to organism and offspring course this " The clock " Another settlement at play an important role. This result contributes to further explaining human old and feeble mechanism and nerve cell. SIR2 gene is an important gene correlated to biological life-span size concerned by person for a long time. Various living beings include the human SIR2 genetic homology is very strong. However, have something that expresses the law about this gene, how it is to interact with other genes, how to influence the cell life-span, have not been well explained yet. Liu BeiDong, through to the deepening discussion of unsymmetry distribution of damaged albumen in yeast cells, the stable fibrous structure of observing protein polymer forms in cells is coincident with position of skeleton structure of actin, strike cells out and polarise the segregation that the mechanism causes protein polymer of cell to lack etc., have further verified the segregation of protein polymer is actin and polarises the initiative course that the mechanism participates in, polarise the direct evidence that the body plays an important role in this course after putting forward cells, therefore correction think, should it isolates mechanisms to be one totally passive idea of course in the past. The department of biology of institute of technology of Masschusetts receives the special professor of many brother's human relations writes specially gently on the " cell " periodical of the same period, recommend this research results and for high evaluation.
