Research ArticleOpen accessIn the keywordsInhibition of U6 snRNA Transcription by PTENStephanie Cabarcas, Kounosuke Watabe, Laura SchrammProblem statement: RNA polymerase III (RNA pol III) is responsible for transcribing many of the small structural RNA molecules involved in RNA processing and protein translation, thereby regulating the growth rate of a cell. RNA pol III transcribes both gene internal (tRNA) and gene external (U6 snRNA) promoters and proper initiation by RNA polymerase III requires the transcription initiation factor … …OnLine Journal of Biological Sciences, Vol. 10, Issue 3 · 30 Sep 2010 · 8,551 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsDetection and Localization of Anti and Pro-apoptotic mRNA Genes in Human Colorectal Cancer Using in situ RT-PCRMohd. Nazil Salleh, Boo Siaw Shi, Wan Khairuzzaman Wan Ramli et al.Problem statement: Recent studies using conventional Polymerase Chain Reaction have shown that anti-apoptotic (Cyclooxygenase-2, COX-2 and Nuclear Factor-κB, NF-κB) and proapoptotic mRNA (Bax and Bad) are involved in the tumorigenesis of colorectal cancer. The aim of this study was to localize the expression of anti and pro-apoptotic mRNA genes using Reverse Transcription in situ Polymerase Chain Reaction (RT in situ … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 7,441 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsWhat these Trends Suggest?Shaomin Yan, Guang WuProblem statement: Global warming is one of most significant factors affecting the biological evolution and the influenza is the disease that threatens humans with possible epidemics or pandemics. It would be important to understand if the global warming would have potential impact on the evolution of influenza virus. For this aim, the first would be to study the trend of … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,883 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsHerpetic Viral RetinitisHidetaka NomaHuman Herpes Virus (HHV) is a DNA virus and is the most important viral pathogen causing intraocular inflammation. HHV is classified into types 1-8. Among these types, HHV-1, HHV-2, HHV-3 Varicella Zoster Virus (VZV) and HHV-5 Cytomegalovirus (CMV) are known to cause herpetic viral retinitis, including acute retinal necrosis and CMV retinitis. Herpes viral retinitis can be diagnosed from characteristic … …Current Research in Virology, Vol. 2, Issue 1 · 29 Jul 2013 · 12,788 accessesView PDF Cite
