Curcumin Inhibits Cell Viability and Increases Apoptosis of SW620 Human Colon Adenocarcinoma Cells via the Caudal Type Homeobox-2 (CDX2)/Wnt/ β-Catenin Pathway.
CONCLUSIONS Curcumin reduced cell viability and increased apoptosis in SW620 human colonic adenocarcinoma cells by restoring CDX2, which inhibited the Wnt/ß-catenin signaling pathway. PMID: 31584928 [PubMed - in process]

Myeloid Derived Suppressor Cells Interactions With Natural Killer Cells and Pro-angiogenic Activities: Roles in Tumor Progression
Conclusions MDSC are major players in the immunosuppressive scenario in cancer, thanks to their phenotype heterogeneity and critical interaction with several innate immune cells, thus representing a crucial target in oncology. Here we reviewed the interactions of MDSCs with NK cells. The contribution of key cytokines, chemokines and mediators active in this process have been discussed. We also described the contribution of MDSC on angiogenesis directly or indirectly through interactions with NK and immunosuppressive activities. A parallel of the cancer associated to the decidual counterpart of these cells is discussed, a...

Sanguinarine Induces Apoptosis Pathway in Multiple Myeloma Cell Lines via Inhibition of the JaK2/STAT3 Signaling
In this study, we aimed to investigate the potential anti-proliferative and pro-apoptotic activities of SNG in a panel of MM cell lines (U266, IM9, MM1S, and RPMI-8226). SNG treatment of MM cells resulted in a dose-dependent decrease in cell viability through mitochondrial membrane potential loss and activation of caspase 3, 9, and cleavage of PARP. Pre-treatment of MM cells with a universal caspase inhibitor, Z-VAD-FMK, prevented SNG mediated loss of cell viability, apoptosis, and caspase activation, confirming that SNG-mediated apoptosis is caspase-dependent. The SNG-mediated apoptosis appears to be resulted from suppres...

Curcumin inhibits tumor epithelial‑mesenchymal transition by downregulating the Wnt signaling pathway and upregulating NKD2 expression in colon cancer cells.
Authors: Zhang Z, Chen H, Xu C, Song L, Huang L, Lai Y, Wang Y, Chen H, Gu D, Ren L, Yao Q Abstract Tumor invasion and metastasis are closely associated with epithelial‑mesenchymal transition (EMT). EMT refers to epithelial cells under physiological and pathological conditions that are specific to mesenchymal transition. Curcumin inhibits EMT progression via Wnt signaling. The Wnt signaling pathway is a conservative EMT‑related signaling pathway that is involved in the development of various tumors. In the present study, MTS assays were employed to analyze the proliferation of curcumin‑treated cells. Naked c...

Abstract 3903: A sub-set of DCLK1+ve colon cancer stem cells (CSCs) survive curcumin induced autophagy, while co-treatment with curcumin +DCLK1-siRNA eliminates CSCs: Role of long and short isofoms of DCLK1
Conclusion. Our studies strongly suggest that, 1) DCLK1 represents a functional protein for colon cancers, 2) combination of curcumin+DCLK1-siRNA may target and eradicate colon cancer stem cells., and 3) identifying small molecules that inhibit expression of S-isoform may allow to specifically target cancer stem cells, while sparing normal stem cells for cancer treatment purposes.

Abstract 2283: Potent curcumin analog FLLL-12 targets both intrinsic and extrinsic signaling pathways to induce apoptosis in lung cancers
Conclusions: Our results strongly suggest that FLLL-12 is a potent curcumin analog that induces apoptosis of lung cancer cell lines by targeting: (1) intrinsic pathways via transcriptional inhibition of EGFR and AKT and induction of BIM, and (2) extrinsic pathway via induction of DR5. Future in vivo studies using appropriate animal models are warranted for further development of this promising compound for cancer prevention and/or treatment for lung cancer.
