We previously showed that the intrahepatic induction of cytokines such as alpha/beta interferon (IFN-alpha/beta) and gamma interferon (IFN-gamma) inhibits hepatitis B virus (HBV) replication noncytopathically in the livers of transgenic mice. The intracellular pathway(s) responsible for this effect is still poorly understood. To identify interferon (IFN)-inducible intracellular genes that could...
UNLABELLED Middle East respiratory syndrome coronavirus (MERS-CoV) is the first highly pathogenic human coronavirus to emerge since severe acute respiratory syndrome coronavirus (SARS-CoV) in 2002. Like many coronaviruses, MERS-CoV carries genes that encode multiple accessory proteins that are not required for replication of the genome but are likely involved in pathogenesis. Evasion of host in...
To investigate the relative importance of each of the ribose 3'-hydroxyl groups of 2-5A (ppp5' A2'p5'A2'-p5' A) in determining binding to and activation of the 2-5A-dependent endonuclease (RNase L), the 3'-hydroxyl functionality of each adenosine moiety of 2-5A trimer triphosphate was sequentially replaced by hydrogen. The analog in which the 5'-terminal adenosine was replaced by 3'-deoxyadenos...
BACKGROUND Inflammatory breast cancer (IBC) is a rare, highly aggressive form of breast cancer. The mechanism of IBC carcinogenesis remains unknown. We sought to evaluate potential genetic risk factors for IBC and whether or not the IBC cell lines SUM149 and SUM190 demonstrated evidence of viral infection. METHODS We performed single nucleotide polymorphism (SNP) genotyping for 2 variants of ...
گندم نان (Triticum aestivum L.) یکی از مهمترین گیاهان زراعی در جهان میباشد که در معرض پاتوژنهای زیادی قرار میگیرد. مطالعات قبلی در ارتباط با الگوی بیان ژنها نشان داده است که علاوه بر ژنهای اصلی ایجادکننده مقاومت به بیماریها در گندم، ژنهای دفاعی دیگری ازجمله ژن کدکننده آنزیمهای S-Like RNase نیز تظاهر مییابد. در این تحقیق بهمنظور بررسی الگوی بیانژن S-Like RNase، در مقابله با انواع بیم...
The proteolysis of bovine pancreatic ribonuclease by subtilisin has been shown to involve the formation of an enzymically active intermediate which is further degraded to inactive products (1, 2). This paper describes the preparation of the modified active ribonuclease, RNase (S)l and its fractionation into two components, a peptide (S-peptide) and a protein (S-protein). Neither S-peptide nor S...
