تأثیر آدنوزین ´5تری فسفات در القای آپوپتوز و مهار بیان ژن Survivin و واریانت پیرایشی ضد آپوپتوزی SUR-3B آن در سلول های K562

Introduction: Leukemia is a heterogeneous malignant disease in which progression at the level of CD34+ cells has a major impact in drug resistance and relapse. The multi-drug resistance gene product, P-glycoprotein is an inhibitor of apoptosis proteins (IAPs), such as Survivin that are expressed simultaneously with several putative drug resistance parameters in CD34+ leukemia cells. In fact, IA...

Identification of a Novel Splice Site Mutation in RUNX2 Gene in a Family with Rare Autosomal Dominant Cleidocranial Dysplasia

Introduction: Pathogenic variants of RUNX2, a gene that encodes an osteoblast-specific transcription factor, have been shown as the cause of CCD, which is a rare hereditary skeletal and dental disorder with dominant mode of inheritance and a broad range of clinical variability. Due to the relative lack of clinical complications resulting in CCD, the medical diagnosis of this disorder is challen...

Identification of Spata-19 New Variant with Expression beyond Meiotic Phase of Mouse Testis Development

Background: The study of specific genes expressed in the testis is important to understanding testis development and function. Spermatogenesis is an attractive model for the study of gene expression during germ cell differentiation. Spermatogenesis associated-19 (Spata-19) is a recently-identified important spermatogenesis-related gene specifically expressed in testis. Its protein product is in...

ATF-a0, a novel variant of the ATF/CREB transcription factor family, forms a dominant transcription inhibitor in ATF-a heterodimers.

We have isolated a cDNA encoding a variant of the transcription factor ATF-a (called ATF-a0) by screening a HeLa cDNA expression library with a regulatory element of the E-selectin promoter, NF-ELAM1/delta A. Relative to full-length ATF-a, the ATF-a0 cDNA contains a large in-frame deletion of 525 base pairs that removes the P/S/T-rich putative transactivation domain. Using reverse-transcription...
