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...

Major virion low-molecular-weight polypeptides were isolated from the Moloney strain of murine leukemia virus (type C) by agarose chromatography in 6M guanidine hydrochloride and were shown to have molecular weights of 15,000 (p15), 12,000 (p12), and 10,000 (p10) by their elution volumes and by their relative mobilities in sodium dodecyl sulfate-polyacrylamide gels. Each polypeptide could be io...

Variation on chromosome 9p21 is associated with risk of coronary artery disease (CAD). This genomic region contains the CDKN2A and CDKN2B genes which encode the cell cycle regulators p16(INK4a), p14(ARF) and p15(INK4b) and the ANRIL gene which encodes a non-coding RNA. Vascular smooth muscle cell (VSMC) proliferation plays an important role in the pathogenesis of atherosclerosis which causes CA...

PURPOSE The chromosome 9p21 region harbors three tumor suppressor genes, p14(ARF), p15(INK4b), and p16(INK4a), all of which can be targets for hypermethylation-associated inactivation in low-grade gliomas. p16(INK4a) and p15(INK4b) are critically involved in the RB1 pathway, whereas p14(ARF) acts as an upstream regulator of the TP53 pathway. The role of each tumor suppressor pathway in low-grad...

Background Basal cell carcinoma (BCC) is a locally aggressive slowly growing tumour that rarely metastasizes and is mostly seen in older members of the population. Objectives To determine the involvement of the tumour suppressor genes p14, p15, p16 and p53 in BCC. Methods We investigated the integrity of the CDKN2A locus in 15 BCC samples by analysing the presence of allelic imbalance ⁄ loss of...

Down syndrome (DS) is a genetic pathology characterized by intellectual disability and brain hypotrophy. Widespread neurogenesis impairment characterizes the fetal and neonatal DS brain, strongly suggesting that this defect may be a major determinant of mental retardation. Our goal was to establish, in a mouse model for DS, whether early pharmacotherapy improves neurogenesis and cognitive behav...
