Abstract
Xinmailong (XML), a traditional Chinese medicine derived from Periplaneta americana, is commonly used in China to treat chronic heart failure (CHF). However, its pharmacological mechanism remains unclear. In our research, we employed Doxorubicin (Dox) to create a CHF animal model and administered XML treatment to investigate the pharmacological effects of XML on CHF rats by combining transcriptomic and proteomic analyses. XML improved dox-induced CHF and improved cardiac function, and a joint multi-omics analysis demonstrated that it reduced cardiomyocyte fibrosis during CHF. There is further evidence that XML may alleviate cardiomyocyte fibrosis through its effects on the cGMP-PKG signaling pathway or by reducing the expression levels of COL1A1, COL3A1, MMP9, and CXCR2. In this study, the effects of XML on rats with CHF are examined at the transcriptional and protein levels, as well as its mechanism and mode of action in treating CHF. There may be novel therapeutic targets or clinical indications for XML-based CHF therapy resulting from the study's identification of significant differential genes and signaling pathways.
