Key result
HMBOX1 overexpression improves cardiac function and reduces myocardial fibrosis in diabetic cardiomyopathy.
Why the study?
Diabetic cardiomyopathy significantly impairs heart structure and function in diabetic patients, but the role of HMBOX1 in this condition is unclear.
Does HMBOX1 overexpression improve cardiac function and reduce fibrosis and inflammation in a rat model of diabetic cardiomyopathy?
Does HMBOX1 overexpression improve cardiac function and reduce fibrosis and inflammation in a rat model of diabetic cardiomyopathy?
HMBOX1 overexpression alleviates diabetic cardiomyopathy in rats by reducing myocardial fibrosis and inflammation via inhibition of the TGF-β/Smad3 signaling pathway.
HMBOX1 overexpression alleviates fibrosis and inflammation in DCM rats; leaves open therapeutic targeting in human diabetic cardiomyopathy.
This study aimed to investigate the impact of Homeobox containing1 (HMBOX1) on heart structure and function in Diabetic Cardiomyopathy (DCM) rats. DCM is the leading cause of death in diabetic patients, significantly affecting their quality of life. The DCM rat model was created using a high-fat diet and streptozotocin injection. The success of the model was determined by assessing heart weight, diet, urine output, and cardiac function. HMBOX1 expression in cardiomyocytes of normal and DCM rats was compared. HMBOX1 expression was enhanced in DCM rat cardiomyocytes through jugular vein injection of HMBOX1 lentivirus. The effects of HMBOX1 on myocardial structure, function, collagen levels, inflammatory factors, and the TGF-β/Smad3 signaling pathway in DCM rats were evaluated. DCM rats exhibited increased heart weight, diet, and impaired heart function, confirming successful model creation. HMBOX1 expression was significantly lower in DCM rat cardiomyocytes compared to the control group. Augmenting HMBOX1 expression in DCM rat cardiomyocytes improved cardiac function, myocardial morphology, and reduced collagen I and collagen III expression. HMBOX1 also mitigated inflammation in myocardial tissues. Furthermore, HMBOX1 inhibited the TGF-β/Smad3 signaling pathway in DCM rat cardiomyocytes. Overall, HMBOX1 alleviated DCM by reducing myocardial fibrosis and inflammation via TGF-β/Smad3 signaling pathway inhibition

Huang et al. (2023) studied Diabetic Cardiomyopathy. HMBOX1 overexpression via lentivirus vs. Control group (normal and DCM rats without overexpression) was evaluated on Cardiac function, myocardial morphology, collagen levels, inflammatory factors, and TGF-β/Smad3 signaling pathway. Augmenting HMBOX1 expression in DCM rat cardiomyocytes improved cardiac function, reduced myocardial fibrosis and inflammation, and inhibited the TGF-β/Smad3 signaling pathway.
