peppermint has considerable commercial value and widely cultivated for essential oil production, especially menthol. the aim of this study was to determine the quantitative expression of pulegone reductase (pr), menthofuran synthase (mfs) and limonene synthase (ls) genes in menthol biosynthesis pathway in mentha x piperita , using semiquantitative rt-pcr analysis and evaluating menthol producti...
Objective(s): The OCT4B1, as one of OCT4 variants, is expressed in cancer cell lines and tissues more than other variants and plays an important role in apoptosis and stress (heat shock protein) pathways. The present study was designed to determine the effects of OCT4B1 silencing on expressional profile of HSP40 gene family expression in three different human tumor cell lines. Materials and Met...
Background: Both mitochondrial dysfunction and aerobic glycolysis are signs of growing aggressive cancer. If altered metabolism of cancer cell is intended, using the glycolysis inhibitor (2-deoxyglucose (2DG)) would be a viable therapeutic method. The AMP-activated protein kinase (AMPK), as a metabolic sensor, could be activated with metformin and it can also launch a p53-dependent metabolic ch...
تب کیو یک بیماری مشترک بین انسان و دام میباشد که توسط کوکسیلا بورنتی ایجاد می شود، نشخوارکنندگان منبع اصلی عفونت انسانی محسوب می شوند. به طور کلی عفونت کوکسیلا بورنتی در گاو بدون علامت است اما می تواند با مشکلات تناسلی همراه باشد. شیر خام یا محصولات لبنی که از شیر غیرپاستوریزه تهیه می شوند (پنیر) ممکن است آلوده به فرم حاد کوکسیلا بورنتی باشند. هدف از این بررسی، تعیین میزان آلودگی به کوکسیلا بور...
Abstract Background Hypertrophy is a critical process for chondrocyte differentiation and maturation during endochondral ossification, which responsible the formation of long bone postnatal longitudinal growth. Increasing evidence suggests that melatonin, an indole hormone, plays pivotal role in chondrogenesis. However, little known about effects melatonin on terminal chondrocytes. Methods Mese...
In the era of the Human Genome Project, quantitation of gene expression by tumor/host cells is of paramount importance to investigate gene patterns responsible for cancer development, progression and response/resistance to treatment. Quantitative real-time PCR (qrt-PCR) technology has recently reached a level of sensitivity, accuracy and practical ease that support its use as a routine bioinstr...
background: oct4b1, a novel variant of oct4, is expressed in cancer cell lines and tissues. based on our previous reports, oct4b1 appears to have a crucial role in regulating apoptosis as well as stress response [heat shock proteins (hsps)] pathways. the aim of the present study was to determine the effects of oct4b1 silencing on the expression of high molecular weight hsps in three different h...
Disorder in re-methylation process of homocysteine to methionine due to mutation in betaine homocysteine methyltransferase enzyme (BHMT) coding gene, leads to decrease in S-adenosyl methionine (SAM) synthesis which takes part in DNA methylation as a methyl donor. As a result, it can promote hypo-methylation of DNA, chromosome instability, and chromosome missegregation, which in turn is one of t...
تنوع ژنتیکی توس (Betula pendula)، که یک گونه ارزشمند دارویی و در معرض خطر انقراض است، در سطح اندک جمعیت های باقیمانده از آن در نیمرخ شمالی ایران شامل: مارمیشو، سیاه مرزکوه، سنگده و شهرستانک، با استفاده از پلی مورفیسم DNAی کلروپلاستی سه منطقه 3800، 1800 و 2700 جفت بازی و تکنیک PCR-RFLP مطالعه شد. این مناطق به ترتیب CD ، DT و K1K2 نامیده می شوند. درصد جایگاه پلی مورفیک، هتروزیگوتی مورد انتظار (H...
