BACKGROUND This study was aimed to explore the molecular mechanisms of hypertensive nephropathy (HTN). METHODS Gene expression profile of GSE37460, which based on 27 healthy living donor samples (HTN group) and 15 hypertensive nephropathy samples (control group), were downloaded from Gene Expression Omnibus (GEO) database. The differentially expressed genes (DEGs) between two groups were iden...

Novel N1-substituted thymine derivatives related to 1-[(Z)-4-(triphenylmethoxy)-2-butenyl]thymine have been synthesized and evaluated against thymidine kinase-2 (TK-2) and related nucleoside kinases [i.e., Drosophila melanogaster deoxynucleoside kinase (Dm-dNK) and herpes simplex virus type 1 thymidine kinase (HSV-1 TK)]. The thymine base has been tethered to a distal triphenylmethoxy moiety th...

اینترفرون ها وسیله دفاعی بدن علیه ویروس ها می باشند که به سرعت در بدن تولید شده، سلولهای اطراف را به تولید پروتئین هائی که تکثیر ویروس را مهار، یا پاسخ ایمنی و رشد سلولی را کنترل می کنند، تحریک می کنند. در این پژوهش، ژن اینترفرون آلفاb2 پس از تکثیر با آغازگرهای اختصاصی در ناقل بیانی (+)pet-26b تحت کنترل پروموتور t7 و پپتید نشانه پریپلاسمی pelb و با استفاده از آنزیم های برشی ncoi و xhoi کلون گرد...

Cisplatin is a common used chemotherapeutic drug for the treatment of laryngeal cancer. However, drug-resistance is a major obstacle in platinum-based chemotherapy for laryngeal cancer. Recent studies have demonstrated that dysregulation of microRNAs (miRNAs) is responsible for chemoresistance in multiple cancers including laryngeal cancer, but the potential mechanisms are required to be explor...

Infectious bursal disease virus (IBDV) is the causative agent of Gumboro disease, an infectious disease of global economic importance in poultry. Structural protein VP2 of IBDV is the most frequently studied protein due to its significant roles in virus attachment, protective immunity, and serotype specificity. The objective of the present study was to improve the expression of hypervariable re...

Streptokinase is one of the best known thrombolytic agents with widespread clinical use. However, its use is not risk-free due to its immunogenicity, hemorrhagic complications and relatively short half-life in circulation. Specific PEGylation of cysteine residue is a useful technique for reducing most of these complications. The aim of this study was designing and producing a cysteine containin...

The ybxI gene of Bacillus subtilis 168 encodes a preprotein of 267 amino acid residues, including a putative signal peptide of 23 residues. The YbxI primary structure exhibits high similarity scores with two members of the superfamily of the serine penicillin-recognizing enzymes: the class D beta-lactamases and the hydrophilic carboxy-terminal domains of the BlaR and MecR penicillin receptors. ...
