Research ArticleOpen accessIn the keywordsEvidences of Apoptosis in Hepatitis C Virus-Infected Hepatocytes and Peripheral Blood Monocuclear Cells in the Absence of Liver InjuryViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.Understanding the mechanism of Hepatitis C Virus (HCV) pathogenesis is an important part of HCV research. In this study, the presence of apoptosis in HCV-infected liver and Peripheral Blood Mononuclear Cells (PBMC) from patients positive for anti-HCV antibodies and negative for serum HCV-RNA was investigated. The samples obtained from 21 patients were studied by in situ Hybridization (ISH), Immunofluorescence, TUNEL … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,984 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of Transcript Labeling Techniques and Development of a Membrane-based Parallel Gene Expression AssayMark A. Fisher, Bonnie B. Plikaytis, Thomas M. ShinnickAn inexpensive alternative to micro arrays was developed to examine the expression of small sets of genes in parallel and used to compare direct and indirect transcript labeling methods. Psoralen-biotin direct labeling was ~10-fold less sensitive than reverse transcriptase-biotin-dUTP labeling, but the enzymatic method generated higher levels of background noise in miniarray hybridizations. The reproducibility of hybridization intensities was the … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,875 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMagnum Opus: Clustered Regularly Interspaced Short Palindromic Repeats Biology and Prokaryotic Gene SilencingPrem Saran Tirumalai, Ashim Kumar BagchiGene Silencing was a technology that was established in eukaryotic system a decade ago and is being used as a research tool widely. However, prokaryotic gene silencing was not workable, till recently a team of researchers from the University of Georgia have proved it possible. Where they have shown that short motif sequences determines the targets of the prokaryotic Clustered … …American Journal of Immunology, Vol. 9, Issue 4 · 5 Oct 2013 · 7,150 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Silencing of Septin 1 via Synthetic siRNAs in Schizosaccharomyces pombeSemih Ekimler, Merve Yilmazer, Ercan AricanSeptins are evolutionary conserved GTP-binding proteins and form heterooligomers in cells to interact with cytoskeleton. The main roles of septins in cell are cytokines, membrane interactions, vesicle trafficking and microtubule and actin organization. Non-coding RNAs are key players of gene expression regulation. Small-interfering RNAs (siRNAs) belong to non-coding RNAs, are characterized by sequence complementarity to their target mRNAs. siRNAs silence … …OnLine Journal of Biological Sciences, Vol. 17, Issue 1 · 31 Mar 2017 · 7,241 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of Nucleoli in Intact Lymphocytes in Different Mammalian Species and HybridsBaylar Iolchiev, Pavel Klenovitskiy, Vugar Bagirov et al.The purpose of this study was to develop methods for quantitative and qualitative assessment of the activity of the nucleolus using the color intensity of argyrophilic regions and to study the effect of the species feature on the quantitative and qualitative indicators of the nucleoli and nucleolus organizer regions. The experiment involved Ovis aries (n = 40), hybrids of domestic … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 24 Jan 2022 · 6,070 accessesView PDFCite
Research ArticleOpen accessIn the keywordsClinical Significance of Precise Hyperthermic Intraperitoneal Chemotherapy Up-regulation RP11-356I2.2 Restraining the Occurrence and Development of Gastric CancerYu Yan, Feng Yanlin, Feng Jinxin et al.In order to study the therapeutic effect and possible mechanism of Precise Hyperthermic Intraperitoneal Chemotherapy (HIPEC) on gastric cancer, the expression of RP11-356I2.2 in gastric cancer cell lines and tissues was detected by real-time fluorescence quantitative PCR (RT-PCR). Chi-square test was used to analyze the correlation between the expression and clinic pathological parameters. Western blotting was used to detect the … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 4 Jun 2020 · 6,489 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEntropyomics as the Blueprint of the Logic of Normal Cell Division and MalignancyKambiz AfrasiabiProblem statement: In this article I propose a blueprint based on one of the most fundamental laws governing the known universe, namely the second law of thermodynamics and I present support for its central role in initiation of mitosis and relationship of the other sub cellular compartments and their organization. Approach: Life is considered to be the most sophisticated antientropy … …OnLine Journal of Biological Sciences, Vol. 11, Issue 1 · 6 Jul 2011 · 10,378 accessesView PDFCite
Research ArticleOpen accessIn the keywordsQuantum Stem Cell in the Infinity Loop: A New Concept for Our Understanding of the Normal State and CancerKambiz AfrasiabiProblem statement: The scientific community is in need of more rigorous understanding of the mechanism of initiation of mitosis. The complete understanding of the initiation sequence may allow knowledge of the normal and disease states, including cancer. This understanding and knowledge would open the way for developing curative treatment of cancer. This article proposes a mechanism of initiation of mitosis … …OnLine Journal of Biological Sciences, Vol. 10, Issue 2 · 17 Mar 2010 · 8,968 accessesView PDFCite
Research ArticleOpen accessIn the abstractDifferential Expression of Cellular and Exosomal MicroRNA Isolated from Oral Cancer Cells and their Resistance to ChemotherapyBrady Petersen, Carl Yu, Samuel Hutchings et al.MicroRNAs are abundant small non-coding RNA with a variety of known functions, including transcriptional activation and inhibition. Recent evidence has suggested that microRNA expression may influence the responsiveness of some cancers to chemotherapy, including liver and lung cancers. Some evidence has now suggested that specific microRNAs, such as miR-21, miR-155, and miR-375, may influence oral cancer responsiveness to chemotherapy – … …Current Research in Dentistry, Vol. 13, Issue 1 · 29 Jul 2022 · 5,906 accessesView PDFCite
Literature ReviewOpen accessIn the abstractMicroRNAs in Atherosclerosis: Key Players, Diagnostic Potential, and Therapeutic OpportunitiesAnastasia V Poznyak, Stanislav Anatolievich Antonov, Ulyana V. Rozhkova et al.Atherosclerosis is a significant contributor to cardiovascular diseases, often progressing silently over many years before clinical symptoms manifest. The multifaceted pathogenesis of atherosclerosis, involving processes such as endothelial dysfunction and inflammation, presents challenges in early diagnosis and effective treatment. MicroRNAs (miRNAs), a class of non-coding RNA molecules with post-transcriptional gene regulation abilities, have emerged as potential key players in atherosclerosis … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 25 Jul 2026 · 744 accessesView PDFCite
