A rapid isocratic method of high performance liquid chromatography system (HPLC) with a glassy carbon working electrode of electrochemical detector is set up for quantitative detection of trace amount of nitrite ion (NO2¯) in aqueous protein containing cell lysate, cell media, plasma, serum, urine and other body fluids. The solid extraction reversed phase cartridges ...
[ 2 ] - Automatic classification of highly related Malate Dehydrogenase and L-Lactate Dehydrogenase based on 3D-pattern of active sites
Accurate protein function prediction is an important subject in bioinformatics, especially wheresequentially and structurally similar proteins have different functions. Malate dehydrogenaseand L-lactate dehydrogenase are two evolutionary related enzymes, which exist in a widevariety of organisms. These enzymes are sequentially and structurally similar and sharecommon active site residues, spati...
[ 3 ] - مطالعۀ اثر ترکیب گیاهی Gossypol بر حساسیت سلول‌های توموری گلیوبلاستوما به پرتودرمانی به‌روش سنجش کلونی‌زایی
مقدمه: گلیوبلاستوما بدخیم‌ترین و معمول‌ترین فرم تومورهای سیستم عصبی مرکزی می‌باشد. گرچه گلیوبلاستوما به نقاط دوردست متاستاز نمی‌دهد، ولی به‌دلیل حساسیت مکان تومور، جراحی در بسیاری از موارد امکان‌پذیر نمی‌باشد. پرتودرمانی روشی مناسب و مفید جهت مقابله با این نوع تومور می‌باشد که می‌تواند پس از جراحی جهت از بین بردن سلول‌های باقی‌مانده یا به‌تنهایی مورد استفاده قرار گیرد ولی اغلب تومورهای گلیوبلا...
[ 4 ] - دسته بندی اسید های آمینه‌ی هلیکس های غشایی در پروتئین انتقال دهنده ی سروتونین انسانی
مقدمه: پروتئین انتقال دهنده ی سروتونین انسانی (5-HTT) اهمیت بالایی در مطالعات طراحی دارو دارد و به تازگی شش ساختار حاصل از کریستالو گرافی از آن در دسترس قرار گرفته است. در این پژوهش با استفاده از دو مورد از این ساختار ها و دو مدل ساخته شده به روش همولوژی، به مطالعه‌‌ی ترکیب اسید های آمینه ی 5-HTT پرداخته شده است تا درک بهتری از نقش ساختاری و عملکردی هلیکس های غشایی در انتقال دهنده‌ها، و ه...
[ 5 ] - Pectic Acid Effects on Prolactin Secretion in GH3/B6 Rat Pituitary Cell Line
Background: Pectic acid extracted from plants increases the secretion of prolactin (PRL) when injected intravenously into ewes or fed to rats. Fragments of ewe hypophysis and lactating rabbit mammary gland incubated in vitro in the presence of pectic acid secreted more PRL and caseins compared to the controls. However, it is not known whether pectic acid directly stimulates PRL secretion in pi...
[ 6 ] - ANTISENSE RNA TO THE TYPE I INSULIN-LIKE GROWTH FACTOR RECEPTOR REVERSED THE TRANSFORMED PHENOTYPE OF PC-3 HUMAN PROSTATE CANCER CELL LINE IN VITRO
The insulin-like growth factor I receptor (IGF-IR) plays an essential role in the establishment and maintenance of transformed phenotype. Interference with the IGF-IR pathway by antisense causes reversal of the transformed phenotype in many rodent and human tumor cell lines. We stably transfected the PC-3 human prostate cancer cell line with an IGF-IR antisense RNA expression plasmid. The ...
[ 7 ] - TRANSFORMING GROWTH FACTOR β2 UP-REGULATES GM-CSF GENE IN HUMAN BLADDER CARCINOMA CELL LINE HTB 5637
Transforming growth factor betas are multifunctional polypeptides in the cytokine superfamily. They have a growth inhibitory role on hemopoietic progenitor cells in semisolid colony assay as well as in long-term bone-marrow culture. TGF - β2 represses stromal cells, stem cell factor gene transcription, and decreases the stability of c-kit transcripts in hemopoietic cells. TGF-β also modulat...
[ 8 ] - Bioinformatics study of complete amino acid sequences of neuraminidase (NA) antigen of H1N1 influenza viruses from 2006 to 2013 in Iran
Introduction: Influenza is a contagious acute viral disease of the respiratory tract that causes fever, headache, muscle aches and cough. One of the unique features of influenza virus is antigenic variation in viral protein neuraminidase (NA) which causes emergence of new virus variants. NA is responsible for the release and spread of progeny virions. Due to the continuous changes of NA genes, ...
[ 9 ] - Comparison of radiosensitizing effect of Resveratrol on monolayer and spheroid culture of DU145 prostatic cell line
Background: Radiotherapy is an established therapeutic modality for prostate cancer. Resveratrol, a natural antioxidant, has been shown to inhibit carcinogenesis and to block the process of tumor initiation and progression. No data is available on the response of cellular spheroid to Reseveratol. In this study we have examined the effect of Resveratol on the radiation response of human p...
[ 10 ] - The role of Rad51 protein in radioresistance of spheroid model of DU145 prostate carcinoma cell line
Background: Rad51 is a protein with critical role in double strand break repair. Down-regulation of this protein has a significant effect in radiosensitivity of some cell lines like prostate carcinoma. Compared to monolayer cell culture model, the spheroids are more resistant to radiation. The aim of the current study was to determine the Rad51 protein level in DU145 spheroids, and monol...
[ 11 ] - Identification and prioritization genes related to Hypercholesterolemia QTLs using gene ontology and protein interaction networks
Gene identification represents the first step to a better understanding of the physiological role of the underlying protein and disease pathways, which in turn serves as a starting point for developing therapeutic interventions. Familial hypercholesterolemia is a hereditary metabolic disorder characterized by high low-density lipoprotein cholesterol levels. Hypercholesterolemia is a quantitativ...
[ 12 ] - Computational Identification of Micro RNAs and Their Transcript Target(s) in Field Mustard (Brassica rapa L.)
Background: Micro RNAs (miRNAs) are a pivotal part of non-protein-coding endogenous small RNA molecules that regulate the genes involved in plant growth and development, and respond to biotic and abiotic environmental stresses posttranscriptionally.Objective: In the present study, we report the results of a systemic search for identifi cation of new miRNAs in B. rapa using homology-based ...
