Mechanism of reversal of multidrug resistance by curcumin in human colorectal cancer cell line HCT-8/5-FU.
Effect of curcumin on the proliferation, apoptosis, migration, and invasion of human melanoma A375 cells
Malignant melanoma is a melanocytic tumor with a high potential of invasion and metastasis. Curcumin is extracted from Curcuma longa L.; curcumin has anti-tumor efficacy in multiple systemic malignancies. Here, we investigated the effect of curcumin on A375 human melanoma cells. A375 cells were cultivated, passaged, and treated with different concentrations of curcumin. We observed the cellular morphology and determined the migration, invasion, proliferation, and apoptosis of A375 cells in vitro.
Effect of curcumin on p38MAPK expression in DSS-induced murine ulcerative colitis
The aim of this study was to determine the therapeutic effect of curcumin on dextran sulfate sodium-induced ulcerative colitis (UC) and to explore the related mechanism. Sixty mice were randomly divided into 6 groups. A group was the normal control group; B group was the model group; C group was the 1.5 mg/kg dexamethasone group based on the B group; and D, E and F groups were 15, 30, and 60 mg/kg curcumin groups, respectively, based on the B group.
Effects of curcumin on hippocampal expression of NgR and axonal regeneration in Aβ-induced cognitive disorder rats
Curcumin has been widely used for the prevention and treatment of Alzheimer's disease (AD), but its mechanism is still not clear. Inhibitory factors of axonal regeneration have been shown to cause a series of pathophysiological changes in the early period of AD. In this study, the co-receptor (Nogo receptor; NgR) of three axonal growth-inhibitory proteins was examined, and effects of curcumin on spatial learning and memory abilities and hippocampal axonal growth were investigated in amyloid β-protein (Aβ)1-40-induced AD rats.
