Adipocyte glucose
WebDec 12, 2006 · Adipocytes secrete proteins with varied effects on glucose homeostasis. Adipocyte-derived proteins with anti-diabetic action (green arrows) include leptin, adiponectin, omentin and visfatin. Other factors tend to raise blood glucose (red arrows), including resistin, TNF-α and RBP4. TNF-α and human resistin are probably secreted by … WebJun 12, 2016 · A key function of adipocytes is the regulation of lipid and glucose homeostasis. This regulation depends on GLUT4-mediated glucose uptake ( 14 ). GLUT4 is a facilitative diffusion glucose transporter and is the major insulin-regulated glucose transporter in skeletal muscle, heart, and adipocytes ( 14 ).

The adipocyte suspensions were incubated with or without 1 nM insulin in the presence or absence of 1, 3 and 10 mM isobutyric acid, isovaleric acid or acetic acid in a shaking device (100 rpm) at 37°C for 30 minutes. WebOct 5, 2024 · Insulin stimulates glucose uptake in adipose tissue and skeletal muscle by inducing plasma membrane translocation of the glucose transporter GLUT4. Although the small GTPase Rac1 is a key regulator downstream of phosphoinositide 3-kinase (PI3K) and the protein kinase Akt2 in skeletal muscle, it remains unclear whether Rac1 also …
WebApr 13, 2016 · When adipocytes are hypertrophied, enlarged unilocular lipid droplets and expanded cell volume may impede cortical actin dynamics, resulting in improper/deficient translocation of GSVs. This indicates the importance of the adipocyte cytoskeleton in the regulation of adipocyte glucose metabolism in response to insulin. WebThe first one uses tritiated 2-deoxyglucose and is designed to measure insulin-stimulated glucose transport into cultured adipose cells. The second allows one to quantify the degree of Glut4 translocation from an intracellular compartment to the plasma membrane.
