objective(s):an earlier meta-analysis on gene expression data derived from four microarray, two cdna library, and one sage experiment had identified rgs5 as one of only ten non-housekeeping genes that were reported to be expressed in human trabecular meshwork (tm) cells by all studies. rgs5 encodes regulator of g-protein signaling-5. the tm tissue is the route of aqueous fluid outflow, and is r...

Background/aim This study explored the mechanisms of allogeneic graft versus leukemia effect in acute lymphoblastic (ALL) cells by examining whether they change gene expression post-transplant environment containing cytokines and immunosuppressant cyclosporine, if such changes affect ALL cell survival. Materials methods RNASeq was used to assess global flow cytometry measure survival presence T...

background : mdm2, e-cadherin, survivin and her2 genes are involved in the regulation of normal cell growth. however, any crucial change in their expression levels can convert a normal cell into a cancer cell. numerous studies have identified alterations of these gene expression levels in various cancers, particularly in breast cancer. thus, they may be used as diagnostic biomarkers. in this ex...

As many as 59% of the transcription factors in Escherichia coli regulate the transcription rate of their own genes. This suggests that auto-regulation has one or more important functions. Here, one possible function is studied. Often the transcription rate of an auto-regulator is also controlled by additional transcription factors. In these cases, the way the expression of the auto-regulator re...

efg1 transcription factor is believed to be the main regulator of hyphal formation under many different conditions. in addition, it is responsible for positive regulation of the expression of several hyphal-specific genes. sap5, which encodes secreted aspartic proteinase, is one of the mentioned genes and is crucial for pathogenicity properties. in the present work we have established the exper...

Introduction: Oxygen tension is one of the most important stimuli in stem cell biology. In this study, we investigate the considerable influence of hypoxia on CX43 gene expression as one of the most important gap junction on the surface of mesenchymal stem cells. Methods: Mesenchymal stem cells were isolated from C57BL/6 mouse bone marrow and cultured in DMEM medium under low oxygen tension (...

Background: In the previous study, we have shown that the presence of A allele at position -588 in Aγ-globin gene was highly frequent and closely associated with fetal hemoglobin elevation among β-thalassemia intermedia patients. Therefore, we decided to investigate whether this allele (A allele at -588) could result in an increase in Aγ-globin gene expression to ameliorate the severity of the ...

Chronic lymphocytic leukaemia (CLL) is the most common B-cell malignancy in the western world and exists as subtypes with very different clinical courses. Myeloid cell leukemia 1 (Mcl-1) is one member of Bcl-2 family proteins that has been shown to be expressed in various tissues and malignant cells, including CLL, where its expression is significantly associated with a failure to achieve compl...

Background : Hepatitis C virus (HCV) is considered as one of the major pathogenic agents of chronic liver diseases. Previous studies have shown that HCV proteins can interaction with gene regulatory networks such as microRNAs. The aim of this study was to investigate the effect of HCV core protein on the expression of miR-150 in a cell culture model. Materials and Methods: Plasmids expressin...
