Study and claim: A molecule may cause non-smokers to suffer from lung cancer
Why could some persons who never smokes suffer from lung cancer too? The scientific research personnel of U.S.A. and Japan find in the latest research, this may be with a kind of little RNA (ribonucleic acid) known as miR-21 The molecule has something to do.The little RNA molecule can regulate a small molecule of gene expression, have already found over 250 kinds at present, among them the multi-type relates to cancer, miR-21 is exactly one kind of them.New research showed, miR-21 may cause never the smoker would suffer from lung gland cancer.Scientific research personnel say on a new American " journal of national academy of sciences ", they draw the lung and organize samples from 28 lung gland cancer patients never smoking, organized samples to compare with the lung of the persons who suffer from lung gland cancer because of smoking, found finally, miR-21 molecule increases in patient's body of lung cancer not smoking notably.Scientific research personnel claim, more than 10% of the lung cancer happens on person who never smokes, in patient's body of lung cancer of non-smoking, the level of miR-21 molecule is very high, especially as the growth factor receptor gene mutation of epidermis, the level of miR-21 is improved very fast. Previous finding, the growth factor receptor gene mutation of epidermis is one of the main reasons causing the person smoking and not smoking to suffer from lung cancer.In block miR-21, difficult to survive cancer cell these from the intersection of body and the intersection of lung and cancer cell scientific research personnel. Scientific research personnel think, it may be a therapeutic effective method of lung cancer in the future to contain miR-21 molecule.With the enhancement of health consciousness, people pay more and more attention to with the life closely bound up health problem, such as the food security, medical treatment is ensured, medical information,etc., healthy life should be from understanding information begins!More excellent health information please enter:News channel
