Background Luteinizing hormone (LH) is a heterodimeric glycoprotein composed of alpha and beta subunits.This hormone is secreted from the pituitary gland. LH, in women triggers Menstrual cycle and ovulation. In men, LH stimulates production of testosterone, which plays a specialized role in sperm production. Up to day, LH hormone have produced in different ways such as codon optimization and al...

Background Follicle stimulating hormone (FSH)- a hetrodimeric glycoprotein- is secreted by pituitary gland. This hormone stimulates growth and maturation of the follicles in females and sperms in male. Up to now, glycoprotein hormones such as FSH have produced in different cell lines. Among of the mammalian expression systems, the Chinese hamster ovary cells (CHO) have taken into consideration ...

Cervical cancer belongs to the second most frequent kind of in female as well a major cause mortality all over world. MicroRNAs are crucial modulators multiple diseases. Based on GSE86100 database, microRNA-3137 expression was low cervical tissues and difference significant, thus we further probed potential along with mechanism cells. Reverse transcription-quantitative polymerase chain reaction...

κ-casein is a glycosilated protein in mammalian milk that plays an essential role in the milk micelles. control of κ-casein expression reflects this essential role, although an understanding of the mechanisms involved lags behind that of the other milk protein genes. transcriptional regulation, a first mechanism for controlling the development of organisms, is carried out by transcription facto...

BACKGROUND The use of small interfering RNAs (siRNAs) as genetic inhibitors of gene expression has been shown to be an effective way of studying gene function in mammalian cells. Recently, different DNA vectors for expression of small hairpin RNAs (shRNAs) or co-expression of sense and antisense RNAs have been developed that direct siRNA-mediated gene silencing. One expression cassette design t...

Epitope tagging is a method of expressing proteins whereby an epitope for a specific monoclonal antibody is fused to a target protein using recombinant DNA techniques. The aim of this study was to sub-clone the peroxisomal protein (PEP) cDNA into a mammalian expression vector leading to the formation of a  chimeric PEP-cDNA containing the FLAG epitope. The FLAG-PEP recombinant cDNA was construc...

Objective(s): Zinc is an effective factor in the reproductive system. Insulin resistance (IR) is known as an important disorder in patients with polycystic ovary syndrome (PCOS). Mammalian target of rapamycin (mTOR), which controls key cell activities, in particular, is activated in disorders such as PCOS. The present study was conducted to observe the therapeutic effe...

High throughput screenings of single chain Fv (scFv) antibody phage display libraries are currently done as soluble scFvs produced in E.coli. Due to endotoxin contaminations from bacterial cells these preparations cannot be reliably used in mammalian cell based assays. The monovalent nature and lack of Fc in soluble scFvs prevent functional assays that are dependent on target cross linking and/...
