Salinity is one of the most important abiotic stresses that decrease crop production. Transcription factors (TFs) are prominent regulators in plant responses to abiotic stress. In the present study, the expression pattern of four salt-induced genes encoding transcription factors, namely, MYB, RF2, GTF, and ARID was studied in response to salt stress (sodium chloride) and recovery conditions. Th...
Background: Early detection is a key to survival for gastric cancer. Molecular markers such as miRNA (microRNA) can have great importance in the early diagnosis of gastric cancer. Expression of miR-21 and miR-221 are deregulated in many types of human cancers. This study aimed to investigate the differences in miRNA expression patterns within the Iranian population. Methods: Total RNA was extra...
مطالعات بسیاری به کاربرد اندازه گیری مقاومت الکتریکی در تشخیص بازه فحلی، آبستنی و زمان زایمان در گاو اشاره کرده اند و کمترین میزان ver را معادل با زمان استروس دانسته اند. در این مطالعه به بررسی تغییر مقادیر مقاومت الکتریکی واژن در طول چرخه فحلی و همچنین دوره ی پس از تلقیح در گاو شیری نژاد هلشتاین پرداخته شد. اندازه گیری مقاومت الکتریکی واژن بصورت دو بار در روز به همراه اندازه گیری روزانه میزان ...
AbstractTwo Arabidopsis thaliana genes, psr9.2 and psr9.4 appearedto be highly similar to a phosphate-starved induced gene,psr9, isolated from Brassica nigra suspension cells.Sequence analysis classified the encoded polypeptides asmembers of leucine-rich repeat (LRR) proteins superfamily.The sequence of psr9 proteins comprise a unique N-terminalregion e...
Purpose: The aim is to downregulate the expression level of NS as an important factor in sustaining stem cells and certain types of cancer cells self-renewal ability in bone marrow derived mesenchymal stem cells by RNAi strategy and investigate the effects of absence of NS in these cells. Materials and Methods: Double strand NS-specific and control siRNA oligos were designed and transfected in...
background: hoxa11 and hoxa10 are expressed in endometrium throughout the menstrual cycle and show a dramatic increase during the mid-luteal phase at the time of implantation. the expression of these genes is decreased in women with myomas. objective: to determine whether myomectomy would reverse hoxa11 and hoxa10 expression, we evaluated the transcript levels of these genes in the endometria o...
