Optogenetic gene switches allow gene expression control at an unprecedented spatiotemporal resolution. Recently, light-responsive transgene expression systems that are activated by UV-B, blue, or red light have been developed. These systems perform well on their own, but their integration into genetic networks has been hampered by the overlapping absorbance spectra of the photoreceptors. We ide...
amorpha-4, 11-diene synthase (ads) gene is the first and important gene in artemisinin biosynthesis pathway that why for many researchers, the study of how to regulate of this gene is important. transcription factors can change the expression rate of several genes simultaneously. in this study, six wild accessions of artemisia annua, collected from golestan province, were used. many known trans...
MicroRNAs (miRNAs) mainly function as post-transcriptional regulators and are involved in a wide range of physiological and pathophysiological processes such as cell proliferation, differentiation, apoptosis, and tumorigenesis. Mouse testes express a large number of miRNAs. However, the physiological roles of these testicular miRNAs remain largely unknown. Using microarray and quantitative real...
Case Report: Recently a 20-day-old layer flock with mortality has been submitted to the PCR Lab. Infectious Bronchitis Virus (IBV) has been detected in the clinical samples. Results: A phylogenetic tree based on a partial S1 gene sequence showed Iranian IBV variant located in LX4-type cluster. This cluster include all QXIBV-type detected in China and European countries. The highest sequence hom...
We have investigated the mechanism of stimulation of thyroglobulin gene expression by thyrotropin (TSH) and cAMP in rat thyroid FRTL-5 cells. In contrast to the c-fos gene, induction of the thyroglobulin gene by TSH or cAMP is slow (10 h) and sensitive to cycloheximide treatment. We have identified a TSH and cAMP-responsive region of thyroglobulin gene between - 171 and - 140 base pairs from th...
