Cheng-Wei Yang et al.
Pharmaceuticals (Basel, Switzerland), 15(2) (2022-02-27)
JAK1 depletion or downregulation was previously reported to account for coronavirus inhibition. Here, we found that AG1024, an IR (insulin receptor) and IGF-1R (insulin-like growth factor 1 receptor) inhibitor, diminishes JAK1 protein levels and exerts anti-coronaviral activities with EC50 values

We present a solution to regenerate adipose tissue using degradable, soft, pliable 3D-printed scaffolds made of a medical-grade copolymer coated with polydopamine. The problem today is that while printing, the medical grade copolyesters degrade and the scaffolds become very stiff

A long-standing mystery shrouds the mechanism by which catalytically repressed receptor tyrosine kinase domains accomplish transphosphorylation of activation loop (A-loop) tyrosines. Here we show that this reaction proceeds via an asymmetric complex that is thermodynamically disadvantaged because of an electrostatic

Proceedings of the National Academy of Sciences of the United States of America, 105(41), 15872-15877 (2008-10-07)
Ig class switch recombination (CSR) is initiated by activation-induced cytidine deaminase (AID) mediated deamination of the switch (S) regions; the resultant mismatch is processed to yield the DNA breaks required for recombination. Whereas many of the pathways involved in the
Megan T Hoffman et al.
Cellular and molecular gastroenterology and hepatology, 11(2), 349-369 (2020-09-04)
Pancreatic ductal adenocarcinoma (PDA) initiation and progression are accompanied by an immunosuppressive inflammatory response. Here, we evaluated the immunomodulatory role of chemosensory signaling in metaplastic tuft cells (MTCs) by analyzing the role of GNAT3, a gustatory pathway G-protein expressed by
Sandeep Dayal et al.
PloS one, 6(9), e24571-e24571 (2011-09-29)
Antibodies are assembled by a highly orchestrated series of recombination events during B cell development. One of these events, class switch recombination, is required to produce the IgG, IgE and IgA antibody isotypes characteristic of a secondary immune response. The

Overweight and obesity are associated with type 2 diabetes, non-alcoholic fatty liver disease, cardiovascular disease and cancer, but all fat is not equal, as storing excess lipid in subcutaneous white adipose tissue (SWAT) is more metabolically favorable than in visceral
Wei Zou et al.
Cell metabolism, 32(5), 801-813 (2020-10-08)
Adipocytes control bone mass, but the mechanism is unclear. To explore the effect of postnatal adipocyte elimination on bone cells, we mated mice expressing an inducible primate diphtheria toxin receptor (DTR) to those bearing adiponectin (ADQ)-Cre. DTR activation eliminates peripheral

Lipids in health and disease, 10, 37-37 (2011-03-01)
It is well known that high fat diets (HFDs) induce obesity and an increase in proinflammatory adipokines. Interleukin-6 (IL-6) is considered the major inflammatory mediator in obesity. Obesity is associated with a vitamin deficiency, especially of vitamins E and D3.
Theresia Gutmann et al.
The Journal of cell biology, 219(1) (2019-11-16)
Glucose homeostasis and growth essentially depend on the hormone insulin engaging its receptor. Despite biochemical and structural advances, a fundamental contradiction has persisted in the current understanding of insulin ligand-receptor interactions. While biochemistry predicts two distinct insulin binding sites, 1

Frontiers in immunology, 12, 685718-685718 (2021-07-09)
Antigen-specific B cells (ASBCs) can drive autoimmune disease by presenting autoantigen to cognate T cells to drive their activation, proliferation, and effector cell differentiation and/or by differentiating into autoantibody-secreting cells. Autoantibodies are frequently used to predict risk and diagnose several
