BRD4 Interacts with GATA4 to Govern Mitochondrial Homeostasis in Adult Cardiomyocytes

The authors showed that cardiomyocyte-specific deletion of Brd4 in adult mice leads to acute deterioration of cardiac contractile function with mutant animals demonstrating a transcriptomic signature enriched for decreased expression of genes critical for mitochondrial energy production.

Transcriptional Profile of Platelets and iPSC-Derived Megakaryocytes from Whole Genome and RNA Sequencing

In 290 normal subjects from the GeneSTAR Research Study, investigators generated whole genome sequence data from whole blood and RNA sequence data from extracted non-ribosomal RNA from 185 induced pluripotent stem cell-derived megakaryocyte cell lines and 290 blood platelet samples from these subjects.

5-FU Promotes Stemness of Colorectal Cancer via p53-Mediated WNT/β-Catenin Pathway Activation

Researchers indicate p53 as a critical mediator of 5-Fluorouracil (5-FU)-induced cancer stem cell activation via the WNT/β-catenin signaling pathway and highlight the significance of combinatorial treatment of WNT inhibitor and 5-FU as a compelling therapeutic strategy to improve the poor outcomes of current 5-FU-based therapies for colorectal cancer patients.

Single-Cell Multiomics Sequencing Reveals Prevalent Genomic Alterations in Tumor Stromal Cells of Human Colorectal Cancer

To what extent stromal cells in the tumor microenvironment are transformed by colorectal cancer (CRC) cells is unexplored.To dissect alterations in these non-malignant cells, researchers performed single-cell multiomics sequencing of 21 patients with microsatellite-stable colorectal cancers and 6 cancer-free, elderly individuals.

Extracellular Cyclic Dinucleotides Induce Polarized Responses in Barrier Epithelial Cells by Adenosine Signaling

Scientists found that cyclic dinucleotides(CDNs) containing adenosine induced a robust CFTR-mediated chloride secretory response together with cAMP-mediated inhibition of Poly I:C-stimulated IFNβ expression. Signal transduction was strictly polarized to the serosal side of the epithelium, dependent on the extracellular and sequential hydrolysis of CDNs to adenosine by the ectonucleosidases ENPP1 and CD73, and occurred via activation of A2B adenosine receptors.
