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 ...

The substantia nigra pars reticulata (SNR) controls seizures in a sex-specific manner. At postnatal day 15 (P15), SNR infusion of GABA(A) receptor agonist muscimol have proconvulsant effects in males but not in females. In males, administration of an androgen receptor antagonist flutamide between P0-P2 led to the disappearance of the proconvulsant muscimol effects at P15. Thus, activation of an...

This study aimed to evaluate the effect of adding various levels bokashi from gliricidia leaves and goat faeces on growth, production chemical composition arbila's forage, has been carried out for 5 months, was designed with completely randomized, 4 treatments replications, consisting P0: without bokashi, P5: tons bokashi/ha, P10: 10 P15: 15 bokashi/ha. Variables measured were number root nodul...

In metazoans, nuclear export of bulk mRNA is mediated by Tap-p15, a conserved heterodimeric export receptor that cooperates with adaptor RNA-binding proteins. In this article, we show that Thoc5, a subunit of the mammalian TREX complex, binds to a distinct surface on the middle (Ntf2-like) domain of Tap. Notably, adaptor protein Aly and Thoc5 can simultaneously bind to non-overlapping binding s...

G1 progression in mammalian cells requires the activity of the cyclin D-dependent kinases Cdk4 and/or Cdk6 and the cyclin E-dependent kinase Cdk2. Proliferating Mv1Lu mink lung epithelial cells and human keratinocytes contain high levels of the universal Cdk inhibitor p27Kip1 distributed in complexes with Cdk2, Cdk4, and Cdk6. Addition of the antimitogenic cytokine transforming growth factor-be...
