WebApr 14, 2024 · Moreover, tumor cell-adipocyte cocultures dramatically reduced the expression of adipocyte differentiation markers such as hormone-sensitive lipase (HSL), resistin, and adiponectin, coinciding with increased expression of proteases and proinflammatory cytokines (e.g., IL6, IL1β, TNFα) and matrix remodeling proteins (e.g., … WebHormone-sensitive lipase (HSL) is the predominant lipase effector of catecholamine-stimulated lipolysis in adipocytes. HSL-dependent lipolysis in response to catecholamines is mediated by protein kinase A (PKA)-dependent phosphorylation of perilipin A (Peri A), an essential lipid droplet (LD)-associated protein.
