K+ channel[1] |
| In Vitro | Apamin is an 18 amino acid peptide neurotoxin found in apitoxin (bee venom). It has long been known as a specifically selective blocker of Ca2+-activated K+ (SK) channels. Apamin inhibits liver fibrosis in a 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC)-induced mouse model as determined by hematoxylin and eosin staining. Apamin treatment attenuates inflammatory cytokine expression, including IL-6, IFN-γ, TNF-α and IL-1β compared with expression levels in the DDC-fed group[1]. Apamin is an 18 amino acid peptide neurotoxin found in apitoxin (bee venom). Apamin, a neurotoxin extracted from bee venom, specifically binds to a particular class of Ca2+-activated K+ channels which are involved in the slow afterhyperpolarization (S-AHP) that follows action potentials in many excitable cell[2]. |
| In Vivo | To investigate the anti-fibrotic effect of Apamin on ECM deposition in the DDC-fed mice, Liver fibrosis induced by DDC is confirmed by induction of fibrogenic genes, FSP-1, α-smooth muscle actin (α-SMA) and collagen I expression. Expression of α-SMA is strongly expressed in the myofibroblasts and HSCs around the proliferated bile duct in the DDC-fed group and clearly with the Apamin treatment. Moreover, expression of collagen I in the DDC-fed group is significantly increased, especially in the portal tracts[1]. |
| Cell Assay | HSC-T6 cells, an immortalized rat hepatic stellate cell line, which has a stable phenotype and biochemical characteristics. Cells are cultured at 37°C in a humidified incubator under a 5% CO2 atmosphere. HSC-T6 cells are seeded in complete medium for 24 h. The cells are changed to fresh serum-free media containing the indicated concentrations of Apamin (0.5, 1 and 2 µg/mL). After 24 h, the cells are replaced with fresh serum-free media containing 2 ng/mL of TGF-β1 for 24 h[1]. |
| Animal Admin | Mice[1] For induction of liver injury, 8-week-old C57BL/6 male mice (20-25 g) are selected. Male C57BL/6 mice are fed a control diet or a DDC supplemented diet (0.1%) for 4 weeks to induce advanced biliary fibrosis. The mice receive an intraperitoneal injection of Apamin (0.1 mg/kg) dissolved in saline twice a week. Mice are sacrificed after 4 weeks from the first DDC diet administration. |
