Alkylolides and alkenylolides of 198-254 Da such as hexadecan-16-olide and 9-hexadecen-16-olide were chemically synthesized in the present study as new macrocyclic lactones that are structurally different from widespread natural macrocyclic lactones including bryostatin (887 Da) and rhizoxin (613 Da), and were investigated for antitumor activity to Ehrlich ascites tumor cells by mitochondrial d...
Background: VHL (von Hippel-Lindau), Runx-3 (Runt-related transcription factor 3), E-cadherin (Epithelial cadherin), P15 (INK4a, cyclin dependent kinase inhibitor), and P16 (INK4b) genes are essential in hematopoiesis. The aim of this study was to explore the correlation between gene expression and promoter methylation in CD34+ stem cells before and after differentiation to erythroid lineage. M...
چکید ه سابقه و هدف عناصر پیامدهی داخل سلول نظیر P15 و P16 ، نقش به سزایی در تمایز سلولهای اولیه به گونههای سلولی متنوع، ایفا میکنند. فاکتورهای مذکور توسط مکانیسمهای مختلفی در کنترل بیان ژن دخیلند که در بین آنها، اپیژنتیک به خصوص متیلاسیون قابل ذکر است. اهداف اصلی در این مطالعه، پی بردن به وضعیت بیان ژنهای مورد نظر در سلولهای بنیادی CD34+ بند ناف و تعیین تغییرات متیلاسیون ژنهای مو...
Introduction P-15 a fifteen residue synthetic peptide (GTPGPQGIAGQRGVV), is a structural analogue of the cell binding domain of Type 1 collagen [1]. P-15 adsorbed on anorganic bovine mineral (ABM-P15) scaffolds has been shown to enhance bone marrow stromal cell growth [2]. This study aimed to investigate the osteogenic potential of human dental pulp stromal cells (HDPSCs) in monolayer culture c...
Two species of glycosylated type C viral core polyprotein were identified on the surface of AKR spontaneous leukemia cells. One of these cell surface polyproteins was shown by immunoprecipitation to have antigenic determinants of murine leukemia virus p30, p15, p12, and p10; the other had murine leukemia virus p30, p15, and p12, but not p10, determinants. Both species were also expressed on thy...
criteria and 40% in the best schedule (5-day intravenous). This compares favorably with prior experiences with decitabine and 5-azacitidine (CR rates, 6%-20%).4,5 Also, decitabine was less toxic than 5-azacitidine in relation to nausea/vomiting and local skin reactions (pain and induration in 5%-10% of patients on 5-azacitidine). The incidence of 65% of hospitalization is cumulative. As one del...
Hepatocellular carcinogenesis results from dysregulation of oncogenes and tumor suppressors that influence cellular proliferation, differentiation and apoptosis. p15 and p21 are cyclin-dependent kinase inhibitors, which arrest cell proliferation and serve as critical tumor suppressors. Here we report that the E3 ubiquitin ligase RLIM expression is downregulated in hepatocellular carcinoma patie...
The breakpoint on chromosome 20 is not constant; 20qis frequently associated with other cytogenetic abnormalities as del(5q), trisomy 8, trisomy 21, deletions or translocations involving the long arm of chromosome 13; a newly described translocation t(11;20)(p15;q11) resulting in a NUP98TOP1 fusion gene was described in therapy-related myelodysplastic syndrome (RAEB); t(11;20)(p15;q11) is a rar...
Mitochondria support synaptic transmission through production of ATP, sequestration of calcium, synthesis of glutamate, and other vital functions. Surprisingly, less than 50% of hippocampal CA1 presynaptic boutons contain mitochondria, raising the question of whether synapses without mitochondria can sustain changes in efficacy. To address this question, we analyzed synapses from postnatal day ...
