Background: A full dose of corticosteroid is required to induce complete remission (CR) in steroid-sensitive nephrotic syndrome (SSNS), unless it is possible to taper and discontinue along with the course after CR. But the mechanism of this change in steroid sensitivity remains unknown. P-glycoprotein (PGP) can eliminate given corticosteroids from cytoplasm, which results in corticosteroid resistance. Therefore, drug delivery was analyzed using real-time polymerase chain reaction (PCR) of multiple drug-resistant gene 1 ( MDR1 ; encoding PGP) mRNA expression.
The main function of hormone-sensitive lipase is to mobilize the stored fats. Mobilization and Cellular Uptake of Stored Fats (with Animation) HSL functions to hydrolyze either a fatty acid from a triacylglycerol molecule, freeing a fatty acid and diglyceride , or a fatty acid from a diacylglycerol molecule, freeing a fatty acid and monoglyceride. Another enzyme found in adipose tissue, Adipose Triglyceride Lipase (ATGP), has a higher affinity for triglycerides than HSL, and ATGP predominately acts as the enzyme for triglyceride hydrolysis in the adipocyte. HSL is also known as triglyceride lipase, while the enzyme that cleaves the second fatty acid in the triglyceride is known as diglyceride lipase, and the third enzyme that cleaves the final fatty acid is called monoglyceride lipase. Only the initial enzyme is affected by hormones, hence its hormone-sensitive lipase name. The diglyceride and monoglyceride enzymes are tens to hundreds of times faster, hence HSL is the rate-limiting step in cleaving fatty acids from the triglyceride molecule.
