| Outline of Final Research Achievements |
DHRS7C (Dehydrogenase/Reductase (SDR Family) Member 7C) is a novel unknown molecule expressed specifically in heart and skeletal muscle. We found DHRS7c correlates strongly with left ventricular (LV) function from . We herein aimed to investigate the role of DHRS7C in the development of heart failure and to establish as a diagnostic marker of LV dysfunction. We found that DHRS7C is a major regulator of cellular calcium homeostasis, locating in sarcoplasmic reticulum. Moreover, we also found the expression of DHRS7C is regulated by hypoxia inducible factor (HIF-1). We established a suitable condition of antibodies and protocol for ELISA. We found further determination of serum pretreatment condition is necessary in order to obtain higher sensitivity and to reduce background. We are working for measuring the level of DHRS7C in serum from healthy volunteer and heart failure patients.
