American researchers: MMP-8 no " L Carcinogenic" R
Xinhua News Agency Washington 3 The researchers of the electric state-run hygiene research institute of U.S.A. are one kind on March 29 on the 29th in the moon " L Carcinogenic" R The gene " L Redress " . They point out, this kind of actual function which is called MMP-8 gene is the development which inhibits skin carcinoma such as the black plain tumour.
Researchers are in Britain>Say, this kind of gene that they found is ground substance metal protease (MMP) on the magazine One kind in the gene, people had thought in the past MMP-8 was an oncogene, but new research showed, actually a kind of tumour of its inhibits the gene.
Ground substance metal protease can help human body degrade some protein, sunburn and cut, injure, play a key role in the course in skin of repairing. But for a long time, the scientist has been thinking all the time all metal protease genes of ground substance are oncogenes, will increase the risk of suffering from many kinds of cancers such as breast cancer, cancer of colon and black plain tumour.
The further animal experiment verifies too, if inject the cells including normal MMP-8 gene for the experimental mouse, they have not presented symptom of suffering from the black plain tumour. Give experimental mouse inject, include, make a variation the intersection of MMP-8 and cell of gene, they appear the above-mentioned symptom easily, and the lung will take place and shift in tumour.
Researchers point out, " L This research shows, to treating skin carcinoma, can resume or strengthen the medicine of the normal MMP-8 genetic function to develop those in better route, develop those piece, it inhibits to be really carcinogenic the intersection of MMP and medicine of gene. "
Black plain tumour one dangerous very big very difficult skin carcinoma that treat, dry in the sun, initiate black plain main reason of tumour one of while being excessive.
