Curcumin Chemical Structure

Molecular Weight(MW): 368.38

Curcumin is the principal curcuminoid of the popular Indian spice turmeric, which is a member of the ginger family (Zingiberaceae). It is an inhibitor of p300 histone acetylatransferase(IC50~25 μM) and Histone deacetylase; activates Nrf2 pathway and supresses the activation of transcription factor NF-κB.

Curcumin induces the expression of forkhead box protein O1 (FOXO1) through activation of extracellular signal-regulated kinase 1/2 signaling. Curcumin inhibits cell proliferation, which was associated with upregulation of the cyclin-dependent kinase inhibitors, p27 and p21, and downregulation of cyclin D1[2]. Curcumin induces endoplasmic reticulum (ER) stress and mitochondrial dysfunction as evidenced by up-regulation of CCAAT/enhancer binding protein homologous protein (CHOP), phosphorylation of JNK and down-regulation of SERCA2ATPase, release of cytochrome c, decrease of Bcl-2 and reduction of mitochondrial membrane potential in both AGS and HT-29 cells[3].

C4-2 cells were cultured on glass coverslips overnight in 12 well plates. The cells were treated with DMSO (upper panel) or curcumin (20 µM) (lower panel) for 1 h, washed, fixed and immunostained for β-catenin (red) and counter-stained with DAPI (blue). Higher β-catenin staining was observed on the cell surface at 1 h of curcumin treatment, compared to DMSO control treated cells. Original Magnifications 600×.

Effect of curcumin treatment on the cellular localization of β-catenin and PKD1. C4-2 cells treated with curcumin (20 µM) or DMSO for 24 h were immunostained for β-catenin (green) or PKD1 (red) and counter-stained with DAPI (blue). Curcumin treated cells showed lower cytoplasmic and higher membrane β-catenin staining compared to control cells. In addition, while PKD1 was predominantly localized in the cytoplasm in control cells, curcumin treated cells exhibited staining primarily on the cell membrane and in the nucleus (white arrows), with faint cytoplasmic staining.

Effect of curcumin on proliferation of various prostate cancer cell lines. LNCaP, C4-2, DU145 and PC3 cell were treated with curcumin or vehicle control DMSO for 48 h and cell proliferation was determined using MTS assay. The percent cell proliferation was calculated by normalizing the proliferation of curcumin treated cells with proliferation of control treated cells. Concentration dependent inhibition in cell proliferation was observed with curcumin treatment. Mean ± SE; n = 3; *p<0.05.

Cell viability; 

PubMed: 19809577     

Triple negative MDA468, HCC1806, and HCC1937, and ER+/HER2-over-expressing BT474, HER2-over-expressing SKBR3, ER+ MCF7, and non-transformed MCF12A cells were treated with 5, 10, or 20 μM curcumin for 72 h. Control cells were treated with ethanol corresponding to the highest dose of curcumin, since curcumin is dissolved in ethanol. Surviving cells were counted by trypan blue exclusion. For each treatment group, cell viability is shown as a percentage of the ethanol control group per line. Experiments were done in duplicate or triplicate at least twice. Error bars represent standard deviation between replicates. In comparison to MCF12A non-transformed mammary epithelial cells, curcumin inhibited viability of all cancer lines (**p < 0.005 at 10 μM and 20 μM).

In vivo Chronic treatment with curcumin significantly reverses the CMS-induced behavioral abnormalities in stressed rats. Additionally, curcumin effectively inhibits cytokine gene expression at both the mRNA and the protein level and reduces the activation of NF-κB[4].
