U.S.A.'s latest find : Cells will cause the canceration while lacking a certain protein

U.S.A.'s latest find : Cells will cause the canceration while lacking a certain protein
One in U.S.A. discovers newly, lacks a certain proteining will cause the canceration at the time of the hyperplasia of cell division.
The researchers of American Purdue University are in 10 Monthly magazine>Say, the cytoplasm connects protein 170 (the clip 170) on the network edition Here the intersection of cell and hyperplasia and DNA ' DNA) Distribution respect plays a leading role, if remove this kind of protein, will lose intact DNA and duplicate the function when cells are proliferated, thus cause the canceration.
Researchers explain : " At the time of cell hyperplasia, DNA must be distributed into sub cells equally, if sub cells are inconsistent with master cell, the canceration will take place in they. Normal cells have very strict regulation procedures, in order to avoid unequally to assign, namely the so-called not whole time of sex phenomena . Not whole time of sex phenomena is a sign of the canceration . "
According to researcher's introduction, the cell division is divided into two steps: First, duplicate one's own DNA, and produce two pieces of central body, they can absorb DNA like magnet; After the central body is absorbed DNA lived, cells begin to split, this course is known as having silks to split, will produce two same cells.
However, will cut 170 after rejecting from cells, the central experience formed exceeds two, draw DNA in several different directions, so every central body can't absorb an intact DNA. At this moment, cells produce the confusion, canceration,etc. takes place.
