Research ArticleOpen accessPhrase in the titleHistone Tail Modifications of H3 and H4 during the Physarum polycephalum Cell CycleMarie-Claire Arnaud, Christophe ThirietProblem statement: Histone modifications are required for chromatin activities and are believed to form an epigenetic code. However, the inheritance of the histone post-translational modifications remains unclear. Approach and Results: The aim of this study was to evaluate the histone modifications throughout the cell cycle and to determine whether the histone marks are transferred to daughter cells. Using the naturally … …OnLine Journal of Biological Sciences, Vol. 12, Issue 2 · 29 May 2012 · 7,580 accessesView PDFCite
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 PDFCite
Research ArticleOpen accessPhrase in the titleCryptolepine 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 PDFCite
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 PDFCite
Research ArticleOpen accessEvery word in the titleSecretary IgA Concentrations and plasma Cell Count Changes Associated with the Estrous Cycle in EwesMorteta H. AL-Medhtiy, A. B.Z. Zuki, M. M. Noordin, S. AgungpriyonoProblems statement: The level of uterine Secretory-IgA (S-IgA) and numbers of plasma cells was measured to observe the differences between two stages of estrous cycle (follicular and luteal phase) in the healthy cycling non pregnant ewes. Approach: Twelve ewes were used in this study and they were divided into two groups of 6 animals each according to the stages of … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,189 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Some Fermentation Parameters on Ethanol Production from Beet Molasses by Saccharomyces cerevisiae CAIM13Awatif Abid Al-JudaibiProblem Statement: Some component of fermentation medium showed to reduce the Saccharomyces cerivisae production of ethanol. Approach: This study was designed to evaluate the role of some fermentation parameters in affecting ethanol productivity from beet molasses BM by Saccharomyces cerevisiae CAIM13. Results: Increase in cell concentration (inoculums size) of the yeast above 3.6×105 cells/100 mL decreased the ethanol yield. The … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 25 Jun 2011 · 8,921 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Effect of Rapid Thermal Annealing Towards the Performance of Screen-Printed Si Solar CellShahrul Anizan, Cheow Siu Leong, Khairymaza Lee Yusri et al.Problem statement: Solar cells are used to capture the photons which generate the energy. However the efficiency of the cells to turn the amount of photon to electricity needs to be high and so the cells enhancement is needed. This involved the whole process of the developing of the cells, thus annealing process is one of the important steps that … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,224 accessesView PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractDihydroartemisinin Attenuates HBV-Induced Proliferation and Migration in LO2 cells via EMT Pathway ModulationYingde Nong, Caifang Ma, Wei Huang et al.Dihydroartemisinin (DHA), a derivative of artemisinin, possesses well-documented anti-inflammatory properties. This study investigated the inhibitory effects of DHA on hepatitis B virus (HBV)-induced cellular alterations in LO2 cells and elucidated underlying molecular mechanisms. Serum interleukin-6 (IL-6) levels were measured in HBV patients and analyzed for correlations with HBsAg, anti-HBs, and HBeAg. In vitro, LO2 cells were infected with clinical HBV … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 8 Jan 2026 · 2,071 accessesView PDFCite
