Expression of ER,CyclinD1 in glandular tissue of pubertal mammary hypertrophy / 中华内分泌外科杂志

ABSTRACT

Objective To investigate the expression of the ER,CyclinD1 in breast tissue of pubertal mammary hypertrophy and explore the possible etiology of pubertal mammary hypertrophy.Methods The expression of ER,CyclinD1 was detected by Western-blot in 15 cases of pubertal mammary hypertrophy,15 normal breast tissue and 10 cases of micromastia.Results There was significant difference of the expression of ER,CyclinD1 within breast tissue between pubertal mammary hypertrophy and micromastia(P＜0.01).There was significant difference of the expression of ER,CyclinD1 within breast tissue in pubertal mammary hypertrophy and in normal breast tissue(P＜0.01).There was no difference between the expression of ER,CyclinD1 within breast tissue in micromastia and in normal breast tissue(P＞0.05).Conclusions The expression of ER,CyclinD1 in pubertal mammary hypertrophy are significantly higher than in micromastia and normal breast tissue.The pubertal mammary hypertrophy may be related to the expression status of ER,CyclinD1 within breast tissue.
