Secretion and Metabolism of GIP and GLP1 Incretin Hormones Description This template traces GIP and GLP-1 hormone secretion from K and L cells in the small intestine following nutrient intake, showing their rapid inactivation by DPP-4 and renal excretion by the kidney
Esculetin (ESC) exhibits diverse anticancer mechanisms across different malignancies.(Top left)In hepatocellular carcinoma (HCC), ESC induces ferroptosis through multiple pathways: promoting ferritinophagy-mediated iron release from ferritin, suppressing antioxidant defenses (SLC7A11, GPX4, Nrf2), enhancing ACSL4-dependent lipid peroxidation, and increasing malondialdehyde (MDA) levels, ultimately leading to iron-dependent cell death.(Top right)In colorectal cancer (CRC), ESC disrupts copper homeostasis by upregulating the copper importer SLC31A1 (CTR1) and downregulating the copper exporter ATP7B, resulting in toxic copper accumulation and cuproptosis
This is a common misconception, but they work in completely different ways
