Suppression of GOLM1 by EGCG through HGF/HGFR/AKT/GSK-3 β/β-catenin/c-Myc signaling pathway inhibits cell migration of MDA-MB-231
Food Chem Toxicol. 2021 Sep 15:112574. doi: 10.1016/j.fct.2021.112574. Online ahead of print.ABSTRACTGolgi Membrane Protein 1 (GOLM1) has been identified as a prime target for cancer therapy because it overexpresses in many solid tumors, increases tumor growth and metastasis and leads to unfavorable survival. Though various approaches including siRNA interference and antibody targeting have been attempted, GOLM1 has remained an un-targetable molecule because of its mainly intracellular location and the lack of domains that could possibly be interfered with by small molecules. Numerous natural anti-tumoral plant substances ...

Targeting HMGB1 inhibits T-2 toxin-induced neurotoxicity via regulation of oxidative stress, neuroinflammation and neuronal apoptosis
Food Chem Toxicol. 2021 Mar 21:112134. doi: 10.1016/j.fct.2021.112134. Online ahead of print.ABSTRACTT-2 toxin, a food-derived mycotoxin, has been identified as a neurotoxin. Nonetheless, T-2 toxin-induced neuroinflammation has never been revealed. As an important therapeutic target for inflammatory diseases and cancers, the role of high mobility group B1 (HMGB1) in mycotoxin-mediated neurotoxicity remains a mystery. In current study, we found that PC12 cells were sensitive to trace amounts of T-2 toxin less than 12 ng/mL, distinguished by decreased cell viability and increased release of lactate dehydrogenase (LDH). Oxida...

The curcumin analogue WZ35 affects glycolysis inhibition of gastric cancer cells through ROS-YAP-JNK pathway.
Abstract
To investigate the anti-tumor activities of WZ35 and its possible molecular mechanism, bioinformatics analysis and the hematoxylin-eosin (HE) staining were applied to evaluate the Yes-associated-protein (YAP) level in gastric cancer. Cell counting kit-8 (CCK-8) was used to examine cell viability. Apoptosis was determined by flow cytometry analysis. Seahorse bioenergetics analyzer was used to investigate the alteration of oxygen consumption and aerobic glycolysis rate. SiRNA transfection was applied to silence endogenous YAP. Western blot was performed to detect indicated proteins. We found that treatment ...

Quercetin facilitates cell death and chemosensitivity through RAGE/PI3K/AKT/mTOR axis in human pancreatic cancer cells
In conclusion, the results demonstrated that the molecular mechanisms of quercetin in regulating apoptosis and autophagy-related pathways and increasing GEM chemosensitivity in pancreatic cancer cells involved inhibition of RAGE expression.Graphical abstractThis diagram illustrated that quercetin treatment effectively attenuated RAGE expression to facilitate autophagy, apoptosis, and GEM chemosensitivity in MIA Paca-2 and MIA Paca-2 GEMR cells.

Camptothecin induces c-Myc- and Sp1-mediated hTERT expression in LNCaP cells: Involvement of reactive oxygen species and PI3K/Akt.
Abstract
Camptothecin (CPT), a quinoline alkaloid isolated from Camptotheca acuminate, targets topoisomerase I, which is continuously expressed in cancer cells. However, the molecular mechanisms responsible for CPT-induced telomerase inhibition remain unclear. Unexpectedly, we found that CPT upregulates hTERT expression and concomitantly increases telomerase activity. However, transfection of hTERT-targeting siRNA had no effect on CPT-induced G2/M phase arrest, suggesting that CPT-induced telomerase activation was not related to G2/M phase arrest. CPT simultaneously increased Nrf2 expression and the level of intra...

Apoptotic cell death induced by Z-Ligustilidein human ovarian cancer cells and role of NRF2.
Abstract
Z-Ligustilide is the most potent bioactive component of Angelica sinensis, which is widely used in Chinese traditional medicine. Z-Ligustilide selectively affected ovarian cancer cell survival in a dose dependent manner. Z-Ligustilide induced apoptotic cell death was determined by flow cytometry. We also demonstrated that apoptotic cell death was triggered by Z-Ligustilideinduced oxidative stress and mitochondria played an active role. Mitochondrial polarization was reduced by Z-Ligustilidewhereas mitochondrial superoxide formation was increased. NRF2 was induced by Z-Ligustilide in OVCAR-3 cells at epi...

Fisetin inhibits cell migration via inducing HO-1 and reducing MMPs expression in breast cancer cell lines.
Abstract
Metastasis is commonly seen in advanced stage of cancers, and matrix metalloproteinases (MMPs) are commonly up-regulated and have been identified as critical regulators. In this present study, a flavonoid, fisetin, which can be found in diverse foods, is investigated for its ability to inhibit cell motility, and the underlying mechanism is also studied in breast cancer cells (4T1 and JC cells). We have revealed that fisetin increased HO-1 mRNA and protein expressions. Besides, fisetin also elevated Nrf2 expression in nuclear fraction. By silencing Nrf2, fisetin-induced HO-1 expression was abrogated, sugge...

Potential role of nucleoside diphosphate kinase in myricetin-induced selective apoptosis in colon cancer HCT-15 cells.
In this study, we evaluated the anti-cancer effects induced by MYR treatment in colon cancer HCT-15 cells. To detect cell proliferation, we conducted MTT assay and real time-cell electronic sensing (RT-CES). We next performed comet assay and Annexin V and PI staining to detect cellular apoptotic features. After that, we conducted two-dimensional electrophoresis (2-DE) analysis to identify apoptotic proteins. The results of this analysis revealed that eight spots were differentially expressed. Among the spots, we selected nucleoside diphosphate kinase (NDPK) for further investigation, as it has been shown to regulate canc...
