Anti Cancer

: Resistance of cancer cells to therapy is a challenge for achieving an appropriate therapeutic outcome. Cancer (stem) cells possess several mechanisms for increasing their survival following exposure to toxic agents such as chemotherapy drugs, radiation as well as immunotherapy. Evidences show that apoptosis plays a key role in response of cancer (stem) cells and their multi drug resistance. Modulation of both intrinsic and extrinsic pathways of apoptosis can increase efficiency of tumor response and amplify the therapeutic effect of radiotherapy, chemotherapy, targeted therapy and also immunotherapy. To date, several agents as adjuvant have been proposed to overcome resistance of cancer cells to apoptosis. Natural products are interesting because of low toxicity on normal tissues. Resveratrol is a natural herbal agent that has shown interesting anti-cancer properties. It has been shown to kill cancer cells selectively, while protecting normal cells. Resveratrol can augment reduction/oxidation (redox) reactions, thus increases the production of ceramide and the expression of apoptosis receptors such as Fas ligand (FasL). Resveratrol also triggers some pathways which induce mitochondrial pathway of apoptosis. On the other hand, resveratrol has an inhibitory effect on anti-apoptotic mediators such as nuclear factor κ B (NFκB), cyclooxygenase-2 (COX-2), phosphatidylinositol 3–kinase (PI3K) and mTOR. In this review, we explain the modulatory effects of resveratrol on apoptosis, which can augment the therapeutic efficiency of anti-cancer drugs or radiotherapy.

Induced Apoptosis

Background: Retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) play key roles in the antiviral response, but recent works show that RLR activation elicits anticancer activity as well, including apoptosis. Previously, we demonstrated that the anticancer activity of the RLR agonist Poly(I:C)-HMW/LyoVec™ [Poly(I:C)-HMW] against human lung cancer cells was enhanced by cotreatment with ionizing radiation (IR). In addition, cotreatment with Poly(I:C)-HMW and IR induced apoptosis in a Fas-independent manner, and increased Fas expression on the cell surface. Objective: The current study investigated the resultant hypothesis that Fas ligand (FasL) may enhance apoptosis in lung cancer cells cotreated with Poly(I:C)-HMW+IR. Methods: FasL was added into culture medium at 24 h following cotreatment with Poly(I:C)- HMW+IR, after upregulation of cell surface Fas expression on human lung cancer cells A549 and H1299 have already been discussed. Results: FasL enhanced the apoptosis of A549 and H1299 cells treated with Poly(I:C)-HMW+IR. Similarly, IR alone - and not Poly(I:C)-HMW - resulted in the upregulation of cell surface Fas expression followed by a high response to FasL-induced apoptosis, thus suggesting that the high sensitivity of cells treated with Poly(I:C)-HMW+IR to FasL-induced apoptosis resulted from the cellular response to IR. Finally, knockdown of Fas by siRNA confirmed that the high response of treated cells to FasL-induced apoptosis is dependent on Fas expression. Conclusion: In summary, the present study indicates that upregulated Fas expression following cotreatment with Poly(I:C)-HMW and IR is responsive to FasL-induced apoptosis, and a combination of RLR agonist, IR, and FasL could be a potential promising cancer therapy.

A series of novel thiazolidinone-isatin hybrids have been synthesized through the Knoevenagel reaction of isatin derivatives with synthesized thiazolidinone scaffolds and then evaluated for their in vitro antibacterial effects on Escherichia coli (E.coli) and Staphylococcus aureus (S.aureus). Cytotoxic effects of the compounds on non-small-cell lung cancer cells (A549 cells), breast epithelial cancer cell line (MCF-7), and prostate cancer cells (PC3 cells) were investigated. Among compounds tested for antibacterial activity, S. aureus was susceptible to compound 7d. The most potent compounds against A549, MCF-7, and PC3 tumor cells were found to be 7g. DAPI staining of all cancer cell lines treated with compound 7g, associated with cell death. We finally confirmed that apoptosis occurred in A549 cells by up-regulated Bax expression and down-regulated Bcl-2 expression from the mitochondrial pathway of apoptosis by using the quantitative reverse transcription-polymerase chain reaction (qRT-PCR) method. Our findings suggested that compound 7g may be a good target in designing cancer therapy strategies.
