Abstract Background: Metformin has pleiotropic effects beyond glucose reduction, including tumor inhibition and immune regulation. It enhanced the anti-tumor effects of programmed cell death protein 1 (PD-1) inhibitors in serine/threonine kinase 11 (STK11) mutant non-small cell lung cancer (NSCLC) through an axis inhibition protein 1 (AXIN1)-dependent manner. However, the alterations of tumor metabolism and metabolites upon metformin administration remain unclear. Methods: We performed untargeted metabolomics using liquid chromatography (LC)-mass spectrometry (MS)/MS system and conducted cell experiments to verify the results of bioinformatics analysis. Results: According to the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway database, most… More > Graphic Abstract

Abstract In the present study, we investigated the synergistic effects of targeted methotrexate-selenium nanostructure containing Myc decoy oligodeoxynucleotides along with X-irradiation exposure as a combination therapy on LNCaP prostate cancer cells. Myc decoy ODNs were designed based on the promoter of Bcl-2 gene and analyzed by molecular docking and molecular dynamics assays. ODNs were loaded on the synthesized Se@BSA@Chi-MTX nanostructure. The physicochemical characteristics of nanostructures were determined by FTIR, DLS, UV-vis, TEM, EDX, in vitro release, and hemolysis tests. Subsequently, the cytotoxicity properties of them with and without X-irradiation were investigated by uptake, MTT, cell cycle, apoptosis, and… More > Graphic Abstract

Abstract Marine collagen peptides (MCPs) are natural products prepared by hydrolyzing marine collagen protein through a variety of chemical methods or enzymes. MCPs have a range of structures and biological activities and are widely present in marine species. MCPs also have a small molecular weight, are easily modified, and absorbed by the body. These properties have attracted great interest from researchers studying antioxidant, anti-tumor, and anti-aging activities. MCPs of specific molecular weights have significant anti-tumor activity and no toxic side effects. Thus, MCPs have the potential use as anti-cancer adjuvant drugs.

Abstract Background: Trigonella foenum-graecum Linn. has been extensively used for medicinal purposes. The current study deals with in vitro and in vivo correlation of free radical quenching activity and anticancer potential of seed extracts of Trigonella. Materials and methods: Antioxidant activity was evaluated against DPPH, NO and ABTS via in vitro radical scavenging assay. Cytotoxicity effect of Trigonella seed extract was studied in human embryonic kidney HEK 293 cell line by alamar blue assay. In vivo antioxidant activity in Swiss albino mice model was assessed by studying endogenous antioxidant enzymes such as GSH, GPx, SOD and LPO. Antitumor effect was observed by studying parameters… More >

Abstract The bioactive triterpenoid 3-oxo-6-β-hydroxy-β-amyrin (1) has been isolated from multiple plant sources. In this study, chloroform fraction of Pistacia integerrima extract was processed for the isolation of the compound. The compound identity was confirmed by advanced spectroscopy technique. X-ray crystallography was applied for molecular structure confirmation. In addition, compound 1 was screen for its activity on reversal of MDR (multidrug resistance) mediated by P-gp (P-glycoprotein). This was accomplished by using rhodamine123 exclusion on multidrug-resistant human ABCB1 gene transfected mouse T-lymphoma cell line. Outcomes revealed that MDR reversing effect was comparable to verapamil as positive control in… More >
