Unripe Citrus unshiu peel inhibited pre-adipocyte's differentiation via leptin-PPAR & gamma;/FAS pathway and pro-inflammatory cytokines' release

By 2030 the obese is prospected 20% of female and 14% of male and obesity induces many diseases. The active compounds in unripe C. unshiu peels were defined and anti-obesity effect was evaluated using with 3T3-L1 cell and high-fat diet mouse. In cell study the anti-obesity effect was analyzed using with oil red O stain and western blot and in animal study that was analyzed using with blood chemistry analysis, H & E stain, immunohistochemistry, RT-PCR, and ELISA. Thirty percentage ethanol extract of C. unshiu peels most effectively inhibited preadipocyte's differentiation via PPAR?-C/EBPa pathway. In animal study it decreased the levels of LDL and leptin, suppressed fat accumulation, prevented adipogenesis via controlling PPAR?-C/EBPa-FAS, and inhibited inflammation via down-regulation of IL-18, IL-13, and TNF-a. C. unshiu is a promising candidate for anti-obesity medication and for anti-inflammatory drug via regulating the level of leptin and the active compounds are supposed narirutin and hesperidin.

Automated summary

By 2030, it is estimated that 20% of females and 14% of males will be obese, which leads to various diseases. The active compounds in unripe C. unshiu peels were identified and their anti-obesity effect was evaluated using 3T3-L1 cells and high-fat diet mice. The study found that a 30% ethanol extract of C. unshiu peels effectively inhibited preadipocyte differentiation through the PPARα-C/EBPα pathway. In animal study, it decreased LDL and leptin levels, suppressed fat accumulation, prevented adipogenesis by controlling PPARα-C/EBPα-FAS, and inhibited inflammation by down-regulating IL-18, IL-13, and TNF-α. C. unshiu shows promise as an anti-obesity medication and anti-inflammatory drug, with narirutin and hesperidin being the supposed active compounds.
