    Lung ischemia‐reperfusion (IR) injury is a common clinical pathology associated with high mortality. Ferroptosis, a novel mode of cell death elicited by iron‐dependent phospholipid peroxidation, has been implicated in ischemic events. Acyl‐CoA synthetase long‐chain family member 4 (ACSL4) is one of the main enzymes in pro‐ferroptotic lipid metabolism. In this study, the involvement of ferroptotic death

    Focal and segmental glomerulosclerosis (FSGS) is a histological pattern frequently found in patients with nephrotic syndrome that often progress to end‐stage kidney disease. The initial step in development of this histologically defined entity is injury and ultimately depletion of podocytes, highly arborized interdigitating cells on the glomerular capillaries with important function for the glomerular

    Our previous research revealed that steroid receptor coactivators (Src)‐1 and ‐2 serve a critical cooperative role in production of parturition signals, surfactant protein A and platelet‐activating factor, by the developing mouse fetal lung (MFL). To identify the global landscape of genes in MFL affected by Src‐1/‐2 double‐deficiency, we conducted RNA‐seq analysis of lungs from 18.5 days post‐coitum

    Estrogen receptor alpha (ERα) is a ligand‐dependent transcription regulator, containing two transactivation functional domains, AF‐1 and AF‐2. The selective estrogen receptor modulators (SERMs), including 4‐hydroxytamoxifen (4OHT), activate AF‐1 preferentially rather than AF‐2. However, it is unclear whether this specific function is related to the tissue‐selective functionality of SERMs. Moreover

    5‐hydroxymethylcytosine (5hmC) is an intermediate stage of DNA de‐methylation. Its location in the genome also serves as an important regulatory signal for many biological processes and its levels change significantly with the etiology of Alzheimer's disease (AD). In keeping with this relationship, the TET family of enzymes which convert 5‐methylcytosine (5mC) to 5hmC are responsive to the presence

    Intestinal inflammatory disorders, such as inflammatory bowel disease, are major contributors to mortality and morbidity in humans and animals worldwide. While some native peptides have great potential as therapeutic agents against intestinal inflammation, potential cytotoxicity, anti‐inciting action, and suppression of anti‐inflammatory activity may limit their development as anti‐inflammatory agents

    Importin α proteins play a central role in the transport of cargo from the cytoplasm to the nucleus. In this study, we observed that male knock‐out mice for importin α4, which is encoded by the Kpna4 gene (Kpna4−/−), were subfertile and yielded smaller litter sizes than those of wild‐type (WT) males. In contrast, mice lacking the closely related importin α3 (Kpna3−/−) were fertile. In vitro fertilization

    Topical application of extracellular calreticulin (eCRT), an ER chaperone protein, in animal models enhances wound healing and induces tissue regeneration evidenced by epidermal appendage neogenesis and lack of scarring. In addition to chemoattraction of cells critical to the wound healing process, eCRT induces abundant neo‐dermal extracellular matrix (ECM) formation by 3 days post‐wounding. The purpose

    Decidualization of the endometrial stroma is an essential differentiation process for embryo implantation and maintenance of pregnancy. We previously reported that protein phosphatase 2A (PP2A) acts as a key mediator during cAMP‐induced decidualization of human endometrial stromal cells (hESCs). However, the mechanism underlying its activation has remained obscure in hESCs. In the present study, we

    Mammalian LGR5 and LGR4, markers of adult stem cells, are involved in many physiological functions by enhancing WNT signaling. However, whether LGR5 and LGR4 are coupled to other intracellular signaling pathways to regulate stem cell function remains unknown. Here, we show that LGR5 and LGR4 can constitutively activate NF‐κB signaling in a ligand‐independent manner, which is dependent on their C‐termini

    SCFAs are primarily produced in the colon by bacterial fermentation of nondigestible carbohydrates. Besides providing energy, SCFAs can suppress development of colon cancer. The mechanism, however, remains elusive. Here, we demonstrate that the SCFA propionate upregulates surface expression of the immune stimulatory NKG2D ligands, MICA/B by imposing metabolic changes in dividing cells. Propionate‐mediated
