BackgroundTranscriptional programs control cell fate, and identifying their components is critical for understanding diseases caused by cell lesion, such as podocytopathy. Although many transcription factors (TFs) are necessary for cell-state maintenance in glomeruli, their roles in transcriptional regulation are not well understood.MethodsThe distribution of H3K27ac histones in human glomerulus cells was analyzed to identify superenhancer-associated TFs, and ChIP-seq and transcriptomics were performed to elucidate the regulatory roles of the TFs. Transgenic animal models of disease were further investigated to confirm the roles of specific TFs in podocyte maintenance.ResultsSuperenhancer distribution revealed a group of potential TFs in core regulatory circuits in human glomerulus cells, including FOXC1/2, WT1, and LMX1B. Integration of transcriptome and cistrome data of FOXC1/2 in mice resolved transcriptional regulation in podocyte maintenance. FOXC1/2 regulated differentiation-associated transcription in mature podocytes. In both humans and animal models, mature podocyte injury was accompanied by deregulation of FOXC1/2 expression, and FOXC1/2 overexpression could protect podocytes in zebrafish.ConclusionsFOXC1/2 maintain podocyte differentiation through transcriptional stabilization. The genome-wide chromatin resources support further investigation of TFs’ regulatory roles in glomeruli transcription programs.

: Since the discovery of (2α,3β)-2,3-dihydroxyolean-12-en-28-oic acid, also known as maslinic acid, many studies have examined its biological activity, which has been shown to promote health and resist various diseases. This article focuses on previous research on maslinic acid and mainly reviews its reported effects on cardiovascular diseases, neuroprotection, diabetes, cancer, inflammation, and pathogens. Maslinic acid exerts positive effects on both cell and animal models of disease. Although its mechanism of action has not yet been completely elucidated, maslinic acid is feasible as a nutritional additive and has the potential to be developed as a drug.
