background: recombinant vaccine technology is one of the most developed means in controlling infectious diseases. however, an effective vaccine against shigella is still missing. objective: to evaluate recombinant ipac protein of shigella as a vaccine candidate. methods: in this study we cloned ipac gene into an expression vector in prokaryotic system. the protein expression was evaluated by sd...
background: the impact of cadmium (cd) on male infertility may be related to the interaction with metal-binding proteins known as metallothioneins (mts). trace elements like zinc (zn) have protective effects on testicular damage induced by cd. objective: we determined the effect of zn and low-dose cd pre-treatment on the expression of mt1 and mt2 genes on testicular sertoli cells. materials and...
The basic unit of chromatin is a nucleosome included an octamer of the four core histones and 147 base pairs of DNA. Posttranslational histones modifications affect chromatin structure resulting in gene expression changes. CpG islands hypermethylation within the gene promoter regions and the deacetylation of histone proteins are the most common epigenetic modifications. The aberrant patterns of...
sphingosine-1-phosphate (s1p) is a bioactive platelet-derived sphingolipid involved in regulation, proliferation, differentiation, hypertrophy and anti-apoptosis of cells and activation of satellite cells. the aim of the present study was to investigate s1p as a growth factor in response to resistance training in male wistar rats. 24 eight-week-old male wistar rats (190–250 gr.) were used in th...
Background: Adipose tissue is a main source for isolation of equine mesenchymal stem cells (MSCs) at different ages. It seems that characteristics of adipose-derived MSCs especially gene expression profile are changing along with age increase. A proper reference gene is required for normalizing data in gene expression analysis by qRT-PCR. This study aimed to evaluate whether GAPDH has a stable ...
3,4- Methylenedioxymethamphetamine (MDMA or "Ecstasy") is a psychoactive and hallucinogenic drug of abuse. MDMA has been shown to produce neurotoxicity both in animals and humans. Recently, the vasodilator drugs such as pentoxifylline is one of the new strategies which have been considered as neuroprotector. In this study effect of pentoxifylline on bcl-2 gene expression changes in hippocampus ...
with advent and development of dna recombinant technology and advantages of p. pastoris expression system, fusion (f) protein of pprv expression, because of effective immunodominant role could be an appropriate candidate for production of recombinant vaccine against ppr disease. in this study, f gene of pprv nigeria 75/1 strain (1637 bp) was amplified using rt-pcr and purified. it was then clon...
Background and purpose: Toxoplasma gondii (T. gondii) is an obligatory intracellular protozoan parasite. Toxoplasmosis is highly prevalent and has a great effect on public health, therefor, there is a need for vaccine and sensitive diagnostic procedures. This study aimed at cloning and investigating the expression of ROP13 gene of T. gondii. Materials and methods: In this study, the gene was c...
Background: The major effects of regular exercise on diabetes mellitus are glycemic status improvement and amelioration of cardiovascular dysfunctions. This research examines whether moderate-intensity aerobic exercise can change the gene expression of metalloproteinase-2 and angiostatin in diabetic rats' heart tissue. Materials & Methods: In this experimental study, thirty Wistar rats were ca...
The core promoter, which is generally defined as the region to which RNA Polymerase II is recruited to initiate transcription, plays a pivotal role in the regulation of gene expression. The core promoter consists of different combinations of several short DNA sequences, termed core promoter elements or motifs, which confer specific functional properties to each promoter. Earlier studies that ex...
