Research ArticleOpen accessPhrase in the titleAntiproliferative Effects of Alkaloids Isolated from the Tuber of Stephania venosa via the Induction of Cell Cycle Arrest in Mammalian Cancer Cell LinesSirinapa Nantapap, Chatchanok Loetchutinat, Puttinan Meepowpan et al.Problem statement: S. venosa (Menispermaceae) is used in traditional medicine. The constituents of S. venosa belonging to showed remarkable cytotoxic activity. According to previous research, S. venosa contains several alkaloids, such as protoberberine stephanine cyclanoline and N-methylstepholidine, kamaline, (+)-N-carboxamidostepharine, (-)-O-methylstepharinosine, (-)-stepharinosine, aporphine (-)-O-acethylsukhodiamine and oxostephanosine. The chemical and biological investigations of this plant are interesting to bioassay-guided fractionation, particularly Antiproliferative … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 8,789 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleAnticancer Activities of Styrylpyrone from the Leaves and Twigs of Goniothalamus maewongensis via Cell Cycle ArrestPradit Pradupsri, Chatchanok Loetchutinat, Narong Nuntasaen et al.Problem statement: Goniothalamus maewongensis is one of three new species which are found in Thailand recently. The genus goniothalamus is not only well known for the rich of styrylpyrones but also famous for the potential of biological activities, especially the cytotoxic activity against a number of human cancer cell lines. The phytochemical and biological investigations of this plant are interesting … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,192 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCryptolepine Provokes Changes in the Expression of Cell Cycle Proteins in Growing CellsCharles Ansah, Nigel J. GooderhamProblem statement: Cryptolepine, the antimalarial plant alkaloid is cytotoxic to mammalian cells, but there is rather little understanding of the possible mechanisms involved in the cell-kill action of cryptolepine. Approach: We examined mammalian cells exposed to cryptolepine (0.5-5.0 μM) for effects on the cell cycle and associated alterations in the levels of major regulatory proteins using immunoblotting and flow cytometry. … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 4 · 31 Dec 2009 · 7,396 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnti-Inflammatory Properties of Crude Extracts and Anti-Cancer Properties of Acetone Extract of Moringa Oleifera Lam. Flowers on Cell Line ModelsSandisiwe Maposa, Gloria Aderonke Otunola, Anthony Jide AfolayanIn recent times, Moringa oleifera has earned great interest for its various physiological and therapeutic benefits. Acetone, ethanol, methanol, and aqueous extracts of Moringa oleifera flowers were investigated for anti-inflammatory and anti-cancer potential. Anti-inflammatory capacity was evaluated using the inhibition of nitric oxide production (LPS-induced) on RAW 264.7, and cell viability was appraised with the MTT assay. The potential of … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 15 Apr 2026 · 1,464 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Arid3a Transcription Factor Rescues Natural and RAS-V12-Induced Senescence Via a Rb-Dependent PathwayChristian Schmidt, Dongkyoon Kim, Shawn Mathur et al.Primary cells are protected against oncogenic events by undergoing premature cellular senescence—an irreversible cell cycle arrest activated by mitogenic signaling as well as by overexpression of tumor suppressors, including p16INK4A, p53 and PML. In the human, downregulation of Dril1/E2F-BP1, a transcriptional regulator of E2F, promotes PML-dependent premature senescence and bypass of ant-iproliferative signaling by p19Arf/p53/p21Cip1 and p16INK4a to prevent both … …American Journal of Immunology, Vol. 13, Issue 4 · 4 Nov 2017 · 8,396 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBioactive Compounds from Sponge Associated Bacteria: Anticancer Activity and NRPS-PKS Gene Expression in Different Carbon SourcesJepri Agung Priyanto, Rika Indri Astuti, Jun Nomura, Aris Tri WahyudiSponge associated bacteria with diverse NRPS-PKS genes could be the alternative source of bioactive compounds. This study aimed to analyze the activity as well as the regulatory mechanism regarding the anticancer properties derived from these bacteria against cancer cell lines. Extraction of bacterial metabolites using ethyl acetate solvent resulted yield ranging from 0.003 to 0.016% (w/v). Six extracts of bacterial … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 5 Oct 2017 · 8,886 accessesView PDF Cite

Research ArticleOpen accessIn the abstractQuercetin Iron (III) Complex Enhances Radiation-Induced Cell Death in Human Erythroleukemic Cell Lines by Increasing the Generation of Intracellular ROSJiraporn Kantapan, Krai Daowtak, Kachaporn Gateprayoon et al.Quercetin iron (III) complex (IronQ) is a paramagnetic agent which exhibits several biological effects. Despite extensive studies about quercetin metal complex, the role of complexes to enhance the effect of radiation still remains unexplored. To this end, we determined whether and how IronQ sensitizes cancer cells to Ionizing Radiation (IR). Doxorubicin resistant leukemic cells (K562/Adr) and their parental cell lines … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 16 Jan 2017 · 8,064 accessesView PDF Cite
