Abstract:

During the development of the mammalian cardiovascular system, the formation of a mature and fully functional cardiovascular system needs the fine coordination of the morphogenesis of various molecules, cells, tissues, and organs. Abnormalities in these processes usually lead to serious congenital heart defects. The determination and maintenance of cell fate in multicellular organisms depend to a large extent on the precise timing and control of RNA polymerase II (Pol II) transcription, and the transcription Mediator complex plays an irreplaceable role in the Pol II transcription process. Mediator is an evolutionarily conserved multi-subunit protein complex, including four parts: head, middle, tail, and kinase. It is a functional bridge between transcription factors and basic transcription machines. In recent years, due to the key role of Mediator in the transcriptional regulation of gene expression, many of human heart diseases have been confirmed to be related to specific Mediator gene mutations, such as heart valve defects, translocation of the great arteries, DiGeorge syndrome and some cardiovascular diseases related to energy homeostasis. In this review, we summarize the role of Mediator in cardiovascular development and disease, focusing on the role of Mediator in the development of cardiovascular disease, and provides a broad idea for the research on Mediator-related cardiovascular system development and diseases.

Key words: Mediator complex, transcriptional regulation, cardiovascular development, cardiovascular disease
