In Vitro Pectic acid (2.5-100 μg/mL, 30 min) stimulates the release of prolactin (PRL) in GH3/B6 cells, without affecting the viability of cells[1]. Pectic acid (100 μg/mL-5 mg/mL, 6-48 h) increases cell death and DNA damage in GH3/B6 cells, detected by MTT assay and AO/EB staining[2]. Pectic acid (100 μg/mL-1 mg/mL, 24 h) induces apoptosis in GH3/B6 cells in a dose-dependent manner[2]. Pectic acid (2.5-5 mg/mL, 24 h) induces necrosis in GH3/B6 cells, confirmed by PI staining[2]. Cell Cycle Analysis[2] Cell Line: GH3/B6 cells Concentration: 1 mg/mL Incubation Time: 24 h Result: Induced sub G1 events, and DNA fragmentation, which was correlated with the number of the apoptotic cells.
In Vivo Pectic acid (25 and 100 mg/kg, oral gavage) increases colon length, downregulates disease activity index, histopathological score and proinflammatory cytokine levels in Ulcerative colitis (UC) mice[3]. Pectic acid (6.25 and 12.5 mg/kg, intravenous injection) rescues the reduction in colon length in UC mice[3]. Animal Model: Ulcerative colitis (UC) mice[3] Dosage: 25, 100 mg/kg Administration: Oral gavage Result: Exhibited the longest colon, lowest DAI, and minimum histopathological score. Decreased the proinflammatory cytokines in the colonic tissue of UC mice. Animal Model: Ulcerative colitis (UC) mice[3] Dosage: 6.25, 12.5 mg/kg Administration: Intravenous injection Result: Decreased the spleen and thymus index. Restored the Th17/Treg balance in the spleen and lamina propria of UC mice. Improved the gut microbiota composition.
