Objective. Uterine leiomyomas are the most common gynaecological benign tumour and greatly affect reproductive health and wellbeing. They are the predominant indication for hysterectomy in premenopausal women. Curcumin, a well-known component of turmeric, has been reported to prevent various diseases such as cancer, diabetes and obesity. Previous study reported that curcumin represses the proliferation of several tumour cells. However, there has not been a precise characterisation of the curcumin-induced inhibition of uterine leiomyoma cells. In this study, we investigated the inhibitory effect of curcumin on leiomyoma cells proliferation. Study design. Eker rat-derived uterine leiomyoma cell lines (ELT-3 cells) were used. Cell proliferation was assessed by counting the number of cells and MTS assay. The activation of peroxisome proliferator-activated receptor-gamma (PPARgamma) was evaluated by luciferase assay. Results. We found that curcumin significantly inhibited ELT-3 cell proliferation. PPARgamma was expressed in ELT-3 cells and curcumin acted as a PPARgamma ligand. This inhibitory effect of curcumin was attenuated by the treatment of cells with PPARgamma antagonist. Conclusion. These experimental findings in vitro show that the inhibitory effect of curcumin on ELT-3 cell proliferation occurs through the activation of PPARgamma. Curcumin may be useful as an alternative therapy for uterine leiomyoma.

A yellow-orange dye obtained from tumeric, the powdered root of CURCUMA longa. It is used in the preparation of curcuma paper and the detection of boron. Curcumin appears to possess a spectrum of pharmacological properties, due primarily to its inhibitory effects on metabolic enzymes.
An INTERLEUKIN-6 related cytokine that exhibits pleiotrophic effects on many physiological systems that involve cell proliferation, differentiation, and survival. Leukemia inhibitory factor binds to and acts through the lif receptor.
A synthetic PGE2 analog that has an inhibitory effect on gastric acid secretion, a mucoprotective effect, and a postprandial lowering effect on gastrin. It has been shown to be efficient and safe in the treatment of gastroduodenal ulcers.
A family of nucleotide diphosphate kinases that play a role in a variety of cellular signaling pathways that effect CELL DIFFERENTIATION; CELL PROLIFERATION; and APOPTOSIS. They are considered multifunctional proteins that interact with a variety of cellular proteins and have functions that are unrelated to their enzyme activity.
The decrease in the cell's ability to proliferate with the passing of time. Each cell is programmed for a certain number of cell divisions and at the end of that time proliferation halts. The cell enters a quiescent state after which it experiences CELL DEATH via the process of APOPTOSIS.
