Exosomal Hsp27 protein are associated with heart failure in STZ-induced type 1 diabetic rats.
The researchers evaluated cardiac function by measuring the left ventricular ejection fraction and fractional shortening. Plasma samples were collected to measure the levels of EVs and Hsp27. The presence and levels of Hsp27 within the EVs were analyzed. The researchers observed the protective effect of Hsp27-overexpressed BMSC exosomes on heart failure in the rats. The levels of plasma EVs were lower in these rats compared to the control rats. Additionally, the EVs derived from the plasma of the rats with STZ-induced type 1 diabetes contained lower levels of Hsp27. The overexpression of Hsp27 in BMSCs effectively improved heart failure induced by STZ in the rats. The results of this study suggest that EVs and their cargo, specifically Hsp27, play a role in the development of heart failure in individuals with type 1 diabetes.
期刊介绍：
The International Journal of Biological Macromolecules is a well-established international journal dedicated to research on the chemical and biological aspects of natural macromolecules. Focusing on proteins, macromolecular carbohydrates, glycoproteins, proteoglycans, lignins, biological poly-acids, and nucleic acids, the journal presents the latest findings in molecular structure, properties, biological activities, interactions, modifications, and functional properties. Papers must offer new and novel insights, encompassing related model systems, structural conformational studies, theoretical developments, and analytical techniques. Each paper is required to primarily focus on at least one named biological macromolecule, reflected in the title, abstract, and text.
