Transcription factor NFYa controls cardiomyocyte metabolism and proliferation during fetal heart development [Multiome]

Project description:Cardiomyocytes are highly metabolic cells responsible for generating the contractile force that drives heart function. During fetal development and regeneration, these cells undergo active division but lose their proliferation activity in the adult heart. The mechanisms that coordinate their metabolism and proliferation are not fully understood. Here, we study the developmental functions of the transcription factor NFYa, which we previously identified from regenerating cardiomyocytes. We show that loss of NFYa profoundly alters cardiomyocyte composition, with a decrease in immature regenerative cells and an increase in trabecular and mature cardiomyocytes, as revealed by spatial and single-cell transcriptome analyses. NFYa-deleted cardiomyocytes exhibited reduced proliferation and impaired mitochondrial metabolism, contributing to the cardiac growth defect. NFYa acts as a transcriptional activator of mitochondrial metabolic genes as well as cell-cycle genes in cardiomyocytes through its interaction with the cofactor SP2, providing a direct link between metabolism and proliferation at the gene transcriptional level. Our study reveals a key role of NFYa in regulating cardiac growth before birth and a previously unrecognized transcriptional control mechanism of metabolic genes in the heart, and highlights the importance of mitochondrial metabolism during fetal heart development and regeneration.

Prrx1b restricts fibrosis and promotes Nrg1-dependent cardiomyocyte proliferation during zebrafish heart regeneration

Project description:Fibroblasts are activated to repair the heart following injury. Fibroblast activation in the mammalian heart leads to a permanent fibrotic scar that impairs cardiac function. In other organisms, such as zebrafish, cardiac injury is followed by transient fibrosis and scar-free regeneration. The mechanisms that drive scarring versus scar-free regeneration are not well understood. Here, we show that the homeobox-containing transcription factor Prrx1b is required for scar-free regeneration of the zebrafish heart as the loss of Prrx1b results in excessive fibrosis and impaired cardiomyocyte proliferation. Through lineage tracing and single-cell RNA sequencing we find that Prrx1b is activated in epicardial-derived cells where it restricts TGFβ ligand expression and collagen production. Furthermore, through combined in vitro experiments in human fetal epicardial-derived cells and in vivo rescue experiments in zebrafish, we conclude that Prrx1 stimulates Nrg1 expression and promotes cardiomyocyte proliferation. Collectively, these results indicate that Prrx1 is a key transcription factor that balances fibrosis and regeneration in the injured zebrafish heart.

Single Cell Multiome Atlas of the Human Fetal Retina

Project description:As the light-sensing part of the visual system, the retina is comprised of five classes of neurons, including photoreceptors, horizontal, amacrine, bipolar, and retinal ganglion cells, along with several non-neuronal cell types such as Muller glia. These major cell classes can be further classified into hundreds of distinct cell subtypes. The development of the retina is under tight temporal control where multipotent progenitor cells differentiate into specific mature cell types in a sequential, but overlapping, order. Additionally, the developmental process is under tight spatial control, with cells at the central retina developing earlier than cells at the periphery. To provide a comprehensive view of the human fetal retina at the molecular level and investigate transcriptional regulatory mechanisms controlling the differentiation process, we profiled more than 300,000 single nuclei of the human fetal retina from 12 donors spanning post conception week 10 and 23 with Multiome RNA-seq and ATAC-seq.
