ABSTRACT
Myocardin is a remarkably potent transcriptional coactivator which specifically expresses in cardiovascular system and directly binds to serum response factor.It activates transcription of a subset of SRF-regulated genes encoding cardiomyocytes and smooth muscle cells contractile proteins.Abnormal expression of myocardin is associated with cardiovascular diseases including atherosclerosis,myocardial hypertrophy and hypertension.Here,recent developments in the structure,expression and regulation of myocardin and its relation with cardiovascular diseases are reviewed.
ABSTRACT
Uterine and extrauterine tumors composed of cells featuring endometrial stromal cells often show ovarian sex cord-like structures and smooth muscle differentiation. A few cases of endometrial stromal tumors showing rhabdoid differentiation have been reported. The present case is a 20-year-old woman with endometrial stromal sarcoma that had sex cord-like structures, smooth muscle components and rhabdoid differentiation.
