Objective(s): The use of antisense oligonucleotides (AOs) to restore normal splicing by blocking the recognition of aberrant splice sites by the spliceosome represents an innovative means of potentially controlling certain inherited disorders affected by aberrant splicing. Selection of the appropriate target site is essential in the success of an AO therapy. In this study, in search for a splic...

gastric cancer (gc) is the second most common cancer in the world and a leading cause of cancer-related mortality. methylation of promoter cpg islands (cgis) belonging to tumor suppressor genes causes transcriptional silencing of their corresponding genes leading to carcinogenesis and other disorders. adenomatous polyposis coli (apc) a tumor suppressor gene is inactivated by methylation of prom...

The present study extends our previous work characterizing the behavioral features of autistic-spectrum disorder (ASD) in Down syndrome (DS) using the Aberrant Behavior Checklist (ABC) and Autism Behavior Checklist (AutBehav). We examined which specific behaviors distinguished the behavioral phenotype of DS + ASD from other aberrant behavior disorders in DS, by determining the relative contribu...

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...

Background The SARS-CoV-2 pandemic is a global health problem. Beside the specific pathogenic effect of SARS-CoV-2, incompletely understood deleterious and aberrant host immune responses play critical roles in severe disease. Our objective was to summarise available information on pathophysiology COVID-19. Methods Two reviewers independently identified eligible studies according following PICO ...

background: ras-associated domain family 1 (rassf1a) and hypermethylated in cancer (hic1) genes are methylated more frequently in breast cancer. genetic factors that alter the dna methylation levels in normal and tumor tissues could therefore influence the susceptibility to this tumor phenotype. objective: we determined the frequency of aberrant methylation of hic1 and rassf1a gene promoters an...

Leukemia may be viewed as a clonal expansion of blast cells; however, the role of primitive cells and/or stem cells in disease etiology and progression is unclear. We investigated stem cell involvement in leukemia using fluorescence in situ hybridization (FISH), immunofluorescence labeling of hematopoietic subpopulations, and flow cytometric analysis/sorting to discriminate and quantify cytogen...

background: generation of an effective dendritic cell (dc) based cancer vaccine depends on appropriate differentiation of monocytes in vitro. objective: to compare the effects of monocyte separation methods, flask adherence (flask-dc) and magnetic activated cell sorting (macs-dc), on phenotypic and functional characteristics of resultant dcs. methods: dcs from healthy volunteers were generated ...
