To investigate the effects of increased glucose uptake on T cell function, our laboratory has created a transgenic mouse to overexpress Glut1 in T cells [ 15 ]. Heterochromatin establishment during early mammalian development is regulated by pericentromeric RNA and characterized by non-repressive H3K9me3 Nat Cell Biol . 2020 Jul;22(7):767-778. doi: 10.1038/s41556-020-0536-6. Cancer cells reprogram their metabolism to promote proliferation, survival, and long-term maintenance. The common feature of this altered metabolism is the increased glucose uptake and fermentation of glucose to lactate, which has been known as “Warburg effect”. 2012-07-17 · Primitive erythropoiesis is regulated by miR-126 via nonhematopoietic Vcam-1+ cells.

hydrolysis. Cell growth is tightly controlled by mitogenic signaling pathways and requires the activation of biosynthetic pathways for the generation of macromolecules, including proteins and lipids.

An N-glycosylated 60-kDa PV-1 protein that binds heparin was detected in mouse lung from a single mRNA transcript. In the absence of disulfide bond reduction PV-1 is detected as a dimer or large molecular weight oligomer. In the lung of Cav-1, but not Cav-2, null mice the amount of PV-1 protein is d …

These mice exhibit severely impaired thermogenesis with increased When exposed to thermogenic stimuli, beige adipocytes transiently express UCP1 but lose that expression upon stimuli withdrawal. Altshuler-Keylin et al. investigate beige adipocyte maintenance and show that autophagy-mediated mitochondrial clearance is needed for beige-to-white adipocyte reversal. Inhibition of autophagy maintains functional beige adipocytes even after stimuli withdrawal.

Cell metabolism is regulated by the

We show here that this process is controlled by trafficking of ceramide synthase 1 (CerS1) from the endoplasmic reticulum (ER) to the OMM by a previously uncharacterized p17, which is now renamed protein that mediates ER-mitochondria trafficking (PERMIT). Though ATP -> ADP + Pi rarely spontaneously happens (high activation energy) and is regulated by ATPases, we speculate that ATP production is also spatially regulated.

Upon activation, NLRP3 forms an inflammasome with the adapter ASC, resulting in caspase-1 activation, release of proinflammatory cytokines and cell death. How NLRP3 activation is regulated by transc … 2021-03-01 Cells have evolved to use feedback inhibition to regulate enzyme activity in metabolism, by using the products of the enzymatic reactions to inhibit further enzyme activity.

NLRP3 is a cytosolic pattern recognition receptor that senses microbes and endogenous danger signals. Upon activation, NLRP3 forms an inflammasome with the adapter ASC, resulting in caspase-1 activation, release of proinflammatory cytokines and cell death.
