abstract background and aim: survivin is a new member of inhibitor of apoptosis protein family (iap) that plays an important role in the regulation of cell cycle and inhibition of apoptosis. distinct expression of this gene in tumoral cells versus normal cells introduces it as the fourth major transcriptome in cancers. thyroid carcinoma is the most common endocrine malignancy. considering the h...

Bone morphogenetic protein-3 and 3b (BMP-3 and BMP-3b) together represent a unique subgroup of the BMP family. BMP-3b shares 82% amino acid identity with BMP-3 in the mature region (ligand domain), but only 37% in the pro-region (pro-domain). In osteoblasts, BMP-3 and 3b have similar antagonistic activity against BMP-2, but they are differentially regulated. In developing embryos, BMP-3 and 3b ...

For non-negative integers a,b, and n, let N(a,b;n) be the number of representations n as a sum squares with coefficients 1 or 3 (a ones b threes). Let N⁎(a,b;n) odd We have that N⁎(a,b;8n+a+3b) is triangular numbers It known for satisfying 1≤a+3b≤7, we haveN⁎(a,b;8n+a+3b)=22+(a4)+abN(a,b;8n+a+3b) a+3b=8, haveN⁎(a,b;8n+a+3b)=22+(a4)+ab(N(a,b;8n+a+3b)−N(a,b;(8n+a+3b)/4)). Such identities are not ...

Insulin stimulation of adipocytes results in serine phosphorylation/activation of phosphodiesterase 3B (PDE 3B) and activation of a kinase that phosphorylates PDE 3B in vitro, key events in the antilipolytic action of this hormone. We have investigated the role for p70 S6 kinase, mitogen-activated protein kinases (MAP kinases), and protein kinase B (PKB) in the insulin signaling pathway leading...

Editor’s key points † Ketamine increased neuroapoptosis in neonatal rat pups, which correlated with decreased GSK-3b phosphorylation. † This suggests involvement of this cell survival signalling pathway in anaesthetic neurotoxicity. † Co-administration of lithium mitigated ketamine-induced neurotoxicity and reduction in GSK-3b phosphorylation, providing a potential approach to neuroprotection. ...

BACKGROUND The causative agent of severe acute respiratory syndrome, SARS coronavirus (SARS-CoV) genome encodes several unique group specific accessory proteins with unknown functions. Among them, accessory protein 3b (also known as ORF4) was lately identified as one of the viral interferon antagonist. Recently our lab uncovered a new role for 3b in upregulation of AP-1 transcriptional activity...

The POU4F2/Brn-3b transcription factor has been identified as a potentially novel regulator of key metabolic processes. Loss of this protein in Brn-3b knockout (KO) mice causes profound hyperglycemia and insulin resistance (IR), normally associated with type 2 diabetes (T2D), whereas Brn-3b is reduced in tissues taken from obese mice fed on high-fat diets (HFD), which also develop hyperglycemia...

The Brn-3a and Brn-3b transcription factor have opposite and antagonistic effects in neuroblastoma cells since Brn-3a is associated with differentiation whilst Brn-3b enhances proliferation in these cells. In this study, we demonstrate that like Brn-3a, Brn-3b physically interacts with p53. However, whereas Brn-3a repressed p53 mediated Bax expression but cooperated with p53 to increase p21cip1...
