Aberrant DNA methylation has been reported as an important phenotype in acute myeloid leukemia. However the clinical significance of methylation changes has not been clear yet. In this study methylation Specific Melting Curve Analysis (MS-MCA) and real time PCR was used to assess the CDKN2B promoter hyper-methylation and gene expression in 59 Iranian acute myeloid leukemia (AML) patients. The i...

The aim of this study was to investigate the in vivo and in vitro effects of targeted heme oxygenase-1 (HO-1) silencing on the proliferation and apoptosis of human acute myelocytic leukemia (AML)-M2 cells. Bone marrow mononuclear cells (BMMNCs) were infected by pRNAi-siHO-1-GFP. The viability of the BMMNCs was determined by cell counting kit-8 (CCK-8) assay following daunorubicin (DNR) treatmen...

RATIONALE Hyperlipidemia and type 2 diabetes mellitus (T2DM) severely impair adaptive vascular growth responses in ischemic muscles. This is largely attributed to dysregulated gene expression, although details of the changes are unknown. OBJECTIVE To define the role of promoter methylation in adaptive vascular growth in hyperlipidemia (LDLR(-/-)ApoB(100/100)) and T2DM (IGF-II/LDLR(-/-)ApoB(10...

Abstract Background and Aims Alport's syndrome is the second most common monogenic cause of end-stage renal disease (ESRD). Males with X-linked (XLAS) have a high risk early ESRD development. The aim study was to determine predictors unfavorable prognosis in boys XLAS. Method children genetically confirmed XLAS (n = 84, age 8.7±4.3 yrs, eGFR 102±16.2 ml/min/1.73 m2, 59 pts missense COL4A5 mutat...

Inflammatory M1 spectrum macrophages protect from infection but can cause inflammatory disease and tissue damage, whereas alternatively activated/M2 spectrum macrophages reduce inflammation and promote tissue repair. Modulation of macrophage phenotype may be therapeutically beneficial and requires further understanding of the molecular programs that control macrophage differentiation. A potenti...

Background and Hypothesis: Tumor-associated macrophages (TAMs) are a key component of tumor-infiltrating immune cells. They largely characterized into M1 or M2 types. TAMs express an anti-inflammatory M2-like phenotype, promote tumor progression. However, the role M2-TAMs in driving disease pathogenesis patients with Juvenile myelomonocytic leukemia (JMML), rare form pediatric driven to large e...

Restriction-modification systems consist of a modification enzyme that methylates a specific DNA sequence and a restriction endonuclease that cleaves DNA lacking this epigenetic signature. Their gene expression should be finely regulated because their potential to attack the host bacterial genome needs to be controlled. In the EcoRI system, where the restriction gene is located upstream of the ...

The 5 -flanking region of the mouse opioid receptor (MOR) gene has two promoters, referred to as distal and proximal. MOR mRNA is predominantly initiated by the proximal promoter. Previously, several important cis-elements and transfactors have been shown to play a functional role in the proximal promoter of the MOR gene. In this study, we defined another functional, negative regulatory element...
