XL184 is a small-molecule kinase inhibitor recently included in first-line systemic therapy for patients with advanced, progressive medullary thyroid cancer (MTC). EF24 is a curcumin analog with a high bio-availability, and ZSTK474 is an inhibitor of the PI3K signaling pathway. We investigated the effect of these compounds, alone and in combination, in two RET-mutated TT and MZ-CRC-1 MTC cell lines, and in six mostly RET wild-type human MTC primary cultures. Low IC50 values demonstrated the efficacy of the drugs, while the Combination Index revealed a significant synergistic effect of combinations of XL184+ZSTK474 and XL184+EF24...

Codelivery of chemo-sensitizers with chemotherapeutics using combo nanomedicine is a promising platform for overcoming chemoresistance in breast cancer. However, tumor accumulation of nano-carriers based on enhanced permeability and retention (EPR) effect is confounded by heterogeneity in tumor microenvironment. Adsorption of protein corona on surface of nanoparticle boost up clearance by reticulo-endothelial system. In this study, a surface functionalized magnetic nanocomposite (NC) for codelivery of doxorubicin (DOX) and curcumin (CUR) is developed...

Signal transducer and activator of transcription 3 (STAT3) is a transcription factor that is latent but constitutively activated in many types of cancers. It is well known that STAT3 plays a key role in inflammation-associated tumorigenesis. Curcumin is an anti-inflammatory natural compound isolated from the turmeric (Curcuma longa L., Zingiberaceae) that has been extensively used in a traditional medicine over the centuries. In the present study, we have found that curcumin inhibits STAT3 signaling that is persistently overactivated in H-Ras transformed breast epithelial cells (H-Ras MCF10A)...

Curcumin is a natural dietary polyphenol compound that has various pharmacological activities such as antiproliferative and cancer-preventive activities on tumor cells. Indeed, the role reactive oxygen species (ROS) generated by curcumin on cell death and cell proliferation inhibition in colon cancer is poorly understood. In the present study, we hypothesized that curcumin-induced ROS may promote apoptosis and cell cycle arrest in colon cancer. To test this hypothesis, the apoptosis-inducing potential and cell cycle inhibition effect of ROS induced by curcumin was investigated in Smd4 and p53 mutated HT-29 colon adenocarcinoma cells...
