Actinidia Chinensis Planch roots (acRoots) are used to treat many cancers, although the anti-tumor mechanism by which acRoots inhibit cancer cell growth remains unclear. The present study aims at investigating inhibitory effects of acRoots on human lung cancer cells and potential mechanisms. Our data demonstrate that the inhibitory effects of acRoots on lung cancer cells depend on genetic backgrounds and phenotypes of cells. We furthermore found the expression of metabolism-associated gene profiles varied between acRoots-hypersensitive (H460) or hyposensitive lung cancer cells (H1299) after screening lung cancer cells with different genetic backgrounds. We selected retinoic acid receptor beta (RARB) as the core target within metabolism-associated core gene networks and evaluated RARB changes and roles in cells treated with acRoots at different concentrations and timeframes. Hypersensitive cancer cells with the deletion of RARB expression did not response to the treatment with acRoots, while RARB deletion did not change effects of acRoots on hyposensitive cells. Thus, it seems that RARB as the core target within metabolism-associated networks plays important roles in the regulation of lung cancer cell sensitivity to acRoots.

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.

Aggressive tumor cells mainly rely on glycolysis, and further release vast amounts of lactate and protons by monocarboxylate transporter (MCT), which causes a higher intracellular pH (pHi) and acidic extracellular pH. Isoorientin, a principle flavonoid compound extracted from several plant species, shows various pharmacological activities. However, effects of isoorientin on anticancer and MCT await to explore in human lung cancer cells. Human lung cancer tissues were obtained from cancer patients undergoing surgery, while the human lung adenocarcinoma cells (A549) were bought commercially. Change of pHi was detected by microspectrofluorometry method with a pH-sensitive fluorescent dye, BCECF. MTT and wound-healing assay were used to detect the cell viability and migration, respectively. Western blot techniques and immunocytochemistry staining were used to detect the protein expression. Our results indicated that the expression of MCTs1/4 and CD147 were upregulated significantly in human lung tissues. In experiments of A549 cells, under HEPES-buffer, the resting pHi was 7.47, and isoorientin (1–300[Formula: see text][Formula: see text]M) inhibited functional activity of MCT concentration-dependently (up to [Formula: see text]%). Pretreatment with isoorientin (3–100[Formula: see text][Formula: see text]M) for 24[Formula: see text]h, MCT activity and cell migration were significantly inhibited ([Formula: see text]% and [Formula: see text]%, respectively), while the cell viability was not affected. Moreover, the expression of MCTs1/4, CD147, and matrix metalloproteinase (MMP) 2/9 were significantly down regulated. In summary, MCTs1/4 and CD147 are significantly upregulated in human lung adenocarcinoma tissues, and isoorientin inhibits cells-migration by inhibiting activity/expression of MCTs1/4 and MMPs2/9 in human lung cancer cells. These novel findings suggest that isoorientin could be a promising pharmacological agent for lung cancer.
