Despite these conflicting data about COX-2/ER correlations, a large body of evidence supports that elevated COX-2 expression in breast cancer is a constant feature of high stage disease and a predictor of worse outcome. Upregulation of COX-2 protein has been identified in approximately 40% of cases

In 1989, a missense mutation at codon 102 of the PRNP gene was first reported to be associated with GSS and, in 1991, the same mutation was also found in affected members of the “H” family (Hsiao et al., 1989; Kretzschmar et al., 1991). By 1995, the pedigree of the “H” family included 221 family mem

F901318 is an orotomide, a novel class of antifungals, which inhibits pyridine biosynthesis by blocking dihydroorotate dehydrogenase (URA1) activity [137]. Although this pathway is conserved in humans, human URA1 is only 20% identical to its fungal homolog and it is inhibited 2000-fold less effectiv

A phase I trial has recently evaluated enzalutamide, an anti-androgen agent, in patients with ER- and AR-positive advanced BC to estimate safety and tolerability of enzalutamide therapy alone or in association to anastrozole, exemestane or fulvestrant [65]. The results of major clinical trials with

In receptor binding terminology, both receptor and acceptor contain a receptive site for the ligand, although only the receptor induces a biological function. Moreover, the acceptor lacks an endogenous ligand. Many proteins have been described as receptors for toxic Aβ assemblies, implying a designe

Introduction Nonalcoholic fatty liver disease (NAFLD) is a clinicopathologic spectrum of liver pathologies associated with excessive accumulation of fat in the liver. This spectrum is continuous but can be graded based on pathological features; in increasing severity, these are: bland steatosis,

Neural progenitor cells (NPCs) are self-renewing, multipotent cells that are capable of differentiating into neurons, astrocytes and oligodendrocytes. NPCs are activated in response to a variety of pathological states in neurodegenerative diseases such as Parkinson’s disease and multiple sclerosis,

Small RhoGTPases are single-domain nucleotide-dependent binary switches that act as highly-tuned regulators in signal transduction [1]. The cycling between active GTP-bound and inactive GDP-bound forms allows RhoGTPases to bind to or to dissociate from downstream effectors, respectively [2]. Guanine

The 5α-reductase activity in patients with 21-OHD, as assessed by the 5α-THF to 5β-THF (ratio 3) and by the 5α-17HP to 17HP (ratio 4) ratios, showed a similar pattern of activities (Fig. 2A–C) and significant correlations (ratio 1 vs. ratio 3; rs=0.67; pdutp to the 5α-reducase activity, the activit

Axl, which belongs to the Tyro-Axl-Mer (TAM) family of RTKs, has been reported to regulate a variety of physiological processes including cell survival, proliferation, migration and adhesion, through the activation of the phosphoinositide 3-kinase (PI3K)/V-akt murine thymoma viral oncogene homolog (

Purification of Rv2477c. In order to investigate the catalytic capabilities of Rv2477c, we expressed the protein as an N-terminal histidine-tagged fusion protein in E. coli BL21 cells and purified the protein by cobalt-affinity chromatography. As shown in Fig. 2A, the 65 kDa fusion protein was expre

A different mechanism has been suggested for the role of TRX1 in ASK1 regulation based on disulfide bond-mediated ASK1 multimerization and its reduction through the thiol-reductase activity of TRX1 (Nadeau et al., 2007, Nadeau et al., 2009). In this model, oxidative stress induces intermolecular dis

Apelin/APJ triggers a variety of cellular signaling pathways (Fig. 1). Recent studies from our laboratory showed that apelin-13 induces vascular smooth muscle cell (VSMC) proliferation by the upregulation of Cyclin D1 expression, which is involved in an ERK-dependent activation of Jagged-1/Notch3 si
