DNA of cancer of the stomach changes

Distortion of cancer cell chromosome is accepted cancer cell feature. The DNA inside nucleolus is the corporeal foundation of chromosome, need from the change of molecular level DNA first the change of chromosome. Content of normal nucleolus DNA is stable, do not get phyletic, sexual distinction, reach individual the influence that waits for an element.

DNA of cancer of the stomach changes

Distortion of cancer cell chromosome is accepted cancer cell feature. The DNA inside nucleolus is the corporeal foundation of chromosome, need from the change of molecular level DNA first the change of chromosome. Content of normal nucleolus DNA is stable, do not get phyletic, sexual distinction, reach individual the influence that waits for an element. But when normal stomach mucous membrane to atrophic sex gastritis, when different hyperplasia and cancer cell turn, nuclear DNA content increases by degrees gradually, the metabolization of clew nucleus increases gradually. DNA is the corporeal foundation of segmentation hyperplasia, accordingly, the G1 in cycle of whole cell hyperplasia period the cell enters S period ceaselessly (DNA is synthesized period) , make number of S period cell increases, to the hyperplasia when cancer cell very exuberant, occurrence DNA content is unusual heighten, reason determines nucleolus DNA can regard a biology that diagnoses different of the heavy mucous membrane that spend a stomach hyperplasia and inchoate cancer of the stomach as mark. In recent years art of luminosity of cell of applied shedding type measures content of DNA of cell of cancer of the stomach and behavior of biology of cancer of cancer of the stomach to have affinity, can take a of prognosis of exhibition period cancer of the stomach good index as the evaluation not only, and also be to have direct sense to the choice of plan is being treated after art of cancer of the stomach.
