CherianProblem statement: The primary aim was to study the expression of CD44 protein in the heart valves removed surgically for either stenosis or regurgitation and to study the morphology of valves using histochemical staining. Approach: We studied 107 valves which were collected from the International Centre for Cardio Thoracic and Vascular Diseases. Results: Aortic and mitral valves were obtained from … …American Journal of Infectious Diseases, Vol. 6, Issue 4 · 31 Dec 2010 · 7,406 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOxidized Low-density Lipoprotein Upregulates GM2 Activator Protein Gene ExpressionHidekatsu Yanai, Hiroshi Yoshida, Hironobu Fujiwara et al.Oxidized low-density lipoprotein (LDL) has been shown to be a powerful regulator of gene expression in monocyte-derived macrophage. To determine the effects of oxidized LDL on macrophage gene expression, macrophages incubated with native or oxidized LDL were analyzed by differential display technique. The differentially expressed cDNA (387 bp) fragment by oxidized LDL showed 100% homology to the part of 3’-untranslated … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 7,324 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExpression of Metallothionein-Like Protein 2B Gene Induced by Different Concentrations of Copper in White Spruce (Picea glauca)Megan McKergow, Kabwe NkongoloThe alterations to the expressions of metal transporter genes can induce metal ion uptake to maintain cell homeostasis when metal concentrations are low. Metallothioneins (MTs) are a class of low molecular mass (4-8 kDa), cysteine (Cys)-rich proteins that can bind metals via the thiol groups of their Cys residues. Studies on MT gene expressions in higher plants, such as conifers, … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 25 Dec 2022 · 5,118 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExpression, Purification and Activity Assay of the Recombinant Protein of Catechol-O-Methyltransferase from Chinese White Shrimp (Fenneropenaeus chinensis)Dian-Xiang Li, Xin-Jun Du, Xiao-Fan Zhao, Jin-Xing WangProblem statement: We have previously cloned a gene of Chinese white shrimp Catechol O-Methyltransferase (designated Fc-COMT) and characterized the gene expression pattern. In this study, expression and purification as well as activity assay of the recombinant Fc-COMT was further conducted. Approach: Using pET-30a (+) as a prokaryotic expression vector, the recombinant Fc- COMT was expressed in the supernatant of Escherichia … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 7,770 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCloning and Expression of SCAMP3 in Transgenic Silkworm (Bombyx mori)Selly S. Rajagukguk, Sabar Pambudi, Astari Dwiranti et al.SCAMP3 (Secretory Carrier Membrane Protein 3) is a crucial component of vesicular trafficking pathways and plays important roles in endocytosis and protein recycling. Previous studies demonstrate SCAMP3 dysregulation in various cancers, suggesting potential applications as a biomarker and therapeutic target. Understanding SCAMP3 expression and post-translational processing provides insights into its biological functions and potential applications in cancer diagnostics and therapy. … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 16 Feb 2026 · 1,521 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMolecular Cloning and Heterologous Expression of Human Interferon Alpha2b GeneI. Made Artika, Yemima Budirahardja, Anna Lucia EkowatiHuman alpha Interferons (hIFNα) have been shown to have antiviral, antiproliferative and immunomodulatory activities. The human interferon alpha2b (hIFNα2b), is one of the human interferon alpha2 sub variants, naturally synthesized as a polypeptide of 188 amino acid residues, the first 23 residues of which represents a signal peptide. In the present study, the hIFNα2b gene was expressed after being fused … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 7,835 accessesView PDFCite
