Background: Setting up an in vitro follicle culture system that resembles in vivo ovary condition has high value in research. Additionally, expression evaluation of folliculogenesis involved genes could lead us to the designing of better culture system. Materials and Methods: ovaries of 12-day-old female NMRI mice were removed, 100-130 μm pre-antral follicles were mechanically isolated from fre...
Objective(s) Although, type 2 diabetes is the most frequent type of diabetes, its main cause is yet to be clarified. Several environmental and genetic parameters are believed to be involved in diabetes. It has also been established that cytokines play key roles in pathogenesis of diabetes. Expression of cytokines is different from person to person and in different societies. Several studies sh...
Background and Objective: Axonal transport is a vital process in nervous system. Impairment of motor proteins involved in axonal transport like dynein is a common factor in several neurodegenerative disorders such as amyotrophic lateral sclerosis (ALS). However, no study found on abnormalities in axonal transport due to decreased physical activity and neuropathic pain. Materials and Methods:...
Background and purpose: Although Taype 2 diabetes is the most frequent among different types of diabetes, the cause of it is yet to be clarified. Several environmental and genetic factors are said to be involved in diabetes and it has been established that cytokines play key roles in pathogenesis of diabetes. Expression of cytokins is different from person and in defferent societies. Studies ...
Background & Aims : Pseudomonas aeruginosa is an opportunistic bacterium that is intrinsically resistant to different antimicrobial substances. One reason for this resistance is the expression of multiple drug efflux pumps, such as MexAB-OprM. Analysis of expression of the MexAB–OprM pump such as mexA with RT-PCR especially with commercial kit can largely aid in selection of suitable antibi...
Background: Colorectal cancer is the fourth most common cancer in the world. It is the third largest risk factor for cancer individuals. The number of new cases is rising since 1975. Hyper activities of EGFR family have been reported in various cancers. The purpose of this study was to investigate the expression levels of HER2 in colorectal cancer and its possible association with advanced stag...
Background & Aims : Axonal transport is a vital process in nervous system that protects axons and nerve terminals through supplying proteins, lipids and mitochondria and clearing folded proteins to avoid toxicity. Recently it is reported that impairment of motor proteins involved in axonal transport-like dynactin is a common factor in several neurodegenerative disorders such as Amyotrophic ...
noncoding ribonucleic acids micro-rna is involved in the regulation of gene expression have major roles in the post-transcriptional level. a micro-rna alone several causes down regulation of mrna transcript of the target. thus, small changes in the expression of a micro rna may lead to significant changes in gene expression are different. micro- rna as key regulators of immune cell lineage diff...
Abstract Background and Objective: Agr is the most important regulatory system for the expression of Staphylococcus aureus virulence factors in different conditions. Agr acts as a quorum sensing system in this bacterium which is activated by increased cell concentration during the transition from logarithmic growth phase to stationary phase. Its role is to up...
Background: Ovine follicle stimulation hormone (OFSH) is a pituitary glycoprotein and belongs to the family of glycoprotein hormones. This hormone plays a key role in the function of the reproductive system: it is essential for sertoli cell function and spermatogenesis in testis and it stimulates the growth of ovulatory follicles in females. Ovine FSH hormone is a heterodimeric hormone consisti...
