Estrogen may play an important role also in functional regulation of bone metabolism besides cardiovascular system and central nervous system. Furthermore, estrogen having broad physiological function which in multiplication and canceration of mammary gland or endometrium for estrogen target organ is also well known. However these details are unknown. Endometrium easily influenced one of organ with estrogen. Estrogen is a risk-factor of playing the role central as breast cancer, endometrial cancer and endometrial hyperplasia. For clinical use studies, an estrogen supplement treatment positively performed for the prevention and the medical treatment purpose of osteoporosis or ischemic heart disease which are known as climacteric disturbance after a menopause. This research solved the mechanism related to cell multiplication and canceration of estrogen on the moleculer levels. The new estrogen induced gene was isolated from extracted RNA and searched for the endometrium growth factor.The rate of discovery of the oncogene in endometrial cancer was lowered and that relation with a new estrogen induced gene was not made clearly. Considering this experiment result, the method of isolated a new gene from RNA extracted using the DNA chip method rather than isolation of the gene by classical handmade method is efficient, and the analysis method by which sufficient result is expected is seemed.
