MIR20B has a deteriorating effect in NAFLD by suppressing PPARA, and may serve as a therapeutic target for combination therapy with fenofibrate for NAFLD.
Electron tomography and biochemical approaches demonstrate a direct role for WDR35, beyond integrity of the IFT-A holocomplex, in the formation and fusion of electron-dense-coated vesicles to the ciliary sheath and pocket for delivery of cargos necessary for axoneme elongation.
Super-resolution imaging uncovers sparse occludin vs. clustered ZO1/claudin-5 architecture, and claudin-5 arrangement compacting during blood-brain-barrier tight-junction (TJ) maturation in which TJs become first restrictive to large and later to small molecules.
Novel Cas9 fusion with DNA polymerase delta subunit 3 (POLD3), identified via high-throughput screening of more than 450 DNA repair proteins, enhances editing by speeding up the initiation of DNA repair.
UV irradiation, a major cause of skin damage, leads to selective loss of fibroblasts from the upper dermis via a deregulated inflammatory response, and infiltrating T cells can promote fibroblast survival in UV irradiated skin.
Multi-omic analyses reveal a connection between the integrated stress response and the regulation of redox and amino acid metabolism when the TCA cycle is impaired.
A novel multi-hormones secreting chromaffin-like cell type was identified using single-cell RNA sequencing, suggesting the molecular mechanism of ectopic ACTH and CRH pheochromocytoma associated with Cushing’s syndrome.
