Several signaling pathways and transcription factors control the cell fate in its in vitro development and differentiation. The orchestrated use of these factors results in cell specification. In coculture methods, many of these factors secrete from host cells but control the process. Today, transcription factors required for retinal progenitor cells are well known, but the generation of these ...

the human leukocyte antigen g (hla-g) molecule exhibits limited tissue distribution, low polymorphism and alternative splicings that generate seven hla-g isoforms. hla-g exerts multiple immunoregulatory functions. recent studies indicate an ectopic up-regulation in tumor cells that may favor their escape from anti-tumor immune responses. this study it is an effort to clarify the presence of hla...

this paper elaborates on persian and english orthographic shared aspects to study the effects of l1 persian on learning english as a foreign language. while there are some examples of letter and sound mismatches in the orthographic system of both languages, those of english are more complex than persian. in order to see the effect of the mismatch between orthography and transcription, 40 persia...

manipulation of stress related transcription factors to improve plant stress tolerance is a major goal of current biotechnology researches. myc2 gene encodes a key stress-related transcription factor involved in jasmonate (ja) and abscisic acid (aba) signaling pathways in arabidopsis. brassica napus, as a globally important oilseed crop, is a close relative of arabidopsis.  in the present study...

Bacillus clausii TnrA transcription factor is required for global nitrogen regulation. In order to obtain anoverview of gene regulation by TnrA in B. clausii KSMK16, the entire genome of B. clausii was screened forthe consensus sequence, 5’-TGTNAN7TNACA-3’ known as the TnrA box, and 13 transcription units werefound containing a putative TnrA box. The TnrA targets identified in...

conclusions the prevalence of hbv infection among donors in duhok was comparable with those of reports from other parts of iraq. education and immunization should be initiated to target the high-risk groups. furthermore, a community-based study is recommended to study the prevalence of hbv and hcv infection in the population. background the prevalence of blood borne viral infection is escalatin...

multiple sclerosis (ms) is an inflammatory demyelinating and neurodegenerative disorder of  the  central  nervous  system (cns), which mainly affects  young adults. activated t lymphocytes promote the neuro-inflammatory cascade of ms by secreting pro-inflammatory cytokines and play a significant role in its pathogenesis. t  lymphocytes may trigger the inflammation, which in turn leads to axonal...

conclusions no association was found between tfam promoter methylation and mes. the present study suggests that the tfam promoter methylation is not associated with risk of mes. objectives the aim of study was to investigate the possible association between promoter methylation of mitochondrial transcription factor a (tfam) and mes. patients and methods dna was extracted from peripheral blood o...
