چکیده

Curcumin is potentially therapeutic for malignant diseases. The mechanisms of this effect might involve a combination of antioxidant, immunomodulatory, proapoptotic, and antiangiogenic activities. However, the exact mechanisms are not fully understood. In the present study, we provided evidences that curcumin suppressed the expression of enhancer of zeste homolog 2 (EZH2) in lung cancer cells both transcriptionally and post-transcriptionally. Curcumin inhibited the expression of EZH2 through microRNA (miR)-let 7c and miR-101. Curcumin decreased the expression of NOTCH1 through the inhibition of EZH2. There was a reciprocal regulation between EZH2 and NOTCH1 in lung cancer cells. These observations suggest that curcumin inhibits lung cancer growth and metastasis at least partly through the inhibition of EZH2 and NOTCH1.

Effect of EZH2 Inhibition on Colorectal Cancer Cells: an In Vitro Study

Recently, the epigenetic modifications have been recognized as a regulator of gene expression in various cancers. EZH2 gene is one the most important component of the PRC2 complex. Overexpression of EZH2 was identified in multiple cancers that considered more attractive the EZH2 role as an oncogene. Some studies report that EZH2 contributes to various aspects of colorectal cancer (CRC). However...

Separation of Curcumin from Curcuma longa L. and its Conjugation with Silica Nanoparticles for Anti-cancer Activities

Curcumin is the natural bio-active component of turmeric (Curcuma longa L.) with known therapeutic properties; nevertheless, its biological applications are limited due to its poor bioavailability. To overcome this limitation, curcumin was conjugated with silica nanoparticles. Curcumin was separated from turmeric by microwave-assisted extraction and silica nanoparticles were developed from rice...
