A preprint abstract from biorxiv.org discusses the role of the PIDDosome, a multi-protein complex, in controlling the polyploidization of cardiomyocytes (CMs) during postnatal heart development. The study found that knockout animals lacking the PIDDosome had significantly more polyploid CMs compared to wild-type animals. The PIDDosome was found to start shaping CM ploidy status at postnatal day 7 and reach its peak at day 14. Interestingly, the PIDDosome was found to limit CM polyploidization in a p53-independent manner, but still involving p21. This research provides new insights into the molecular machinery that controls the proliferation of polyploid CMs during postnatal heart development. [Extracted from the article]

A recent study conducted by researchers at Syracuse University explores how Chinese lay Buddhists understand and engage with the concept of the "heart" (xin). The study, based on long-term ethnographic research, reveals that lay Buddhists view the heart as a means of cultivating an authentic self that is separate from the ego-centered and calculating everyday self. Lay Buddhists draw on both Confucian and Chan Buddhist ideas to develop their understanding of the heart, with older, working-class practitioners seeing it as a source of ethical direction and younger, middle-class practitioners turning to it as a therapeutic refuge. Despite these differences, cultivating the heart serves both ethical and therapeutic functions for both groups. The study concludes that the heart is a crucial aspect of lay Buddhist practice in contemporary China. [Extracted from the article]

A recent study conducted by researchers at the University of Lille in France has shed light on the mechanisms behind endothelial-to-mesenchymal transition (EndMT), a process that plays a crucial role in embryonic development and contributes to vascular dysfunction in cardiovascular diseases. The researchers used single-cell RNA sequencing to identify gene signatures associated with EndMT and found that mitochondrial calcium signaling is a key driver of this transition. Inhibiting mitochondrial calcium uptake prevented EndMT in vitro, and deleting the gene responsible for this process in endothelial cells blocked mesenchymal activation in a hind limb ischemia model. These findings suggest that targeting mitochondrial calcium signaling could be a potential therapeutic strategy for cardiovascular diseases. [Extracted from the article]

This article discusses a study on the mechanisms underlying the development of congenital heart disease (CHD) and the robustness of pharyngeal arch artery (PAA) morphogenesis. The researchers found that the number of second heart field (SHF)-derived endothelial cells (ECs) is regulated by VEGFR2 and Tbx1. When the number of SHF-derived ECs is decreased, compensatory ECs from nearby veins can rescue PAA development. However, blocking this compensatory response leads to embryonic demise. The study also found that Tbx1 regulates the recruitment of compensatory ECs in an SHF-non-cell-autonomous manner. Overall, these findings uncover a novel buffering mechanism in PAA development and remodeling. [Extracted from the article]
