The HPV16 oncogenes cause aberrant stem cell mobilization
(2013)Human Papilloma Virus related epithelial cancers have been speculated to derive from virus-infected tissue stem cells. Stem cells also are thought to provide a reservoir of latently infected cells that can persist for long ...

Identification of a potent activator of Akt phosphorylation from a novel series of phenolic, picolinic, pyridino, and hydroxamic zinc(II) complexes
(2011)The discovery of small-molecule modulators of signaling pathways is currently a particularly active area of research. We aimed at developing unprecedented metal-based activators of Akt signaling which can potentially find ...

Inhibition of topoisomerase IIα activity in CHO K1 cells by 2- [(aminopropyl)amino]ethanethiol (WR-1065)
(1994)The aminothiol 2-[(aminopropyl)amino]ethanethiol (WR-1065) is the active thiol of the clinically studied radioprotective agent S-2-(3- aminopropylamino)ethylphosphorothioic acid (WR-2721). WR-1065 is an effective radiation ...

Insulin-mimetic action of vanadium compounds on osteoblast-like cells in culture
(1997)Vanadium compounds mimic insulin actions in different cell types. The present study concerns the insulin-like effects of three vanadium(V) derivatives and one vanadium(IV) complex on osteoblast-like (UMR106 and MC3T3E1) ...

The interplay between DSL proteins and ubiquitin ligases in Notch signaling
(2005)Lateral inhibition is a pattern refining process that generates single neural precursors from a field of equipotent cells and is mediated via Notch signaling. Of the two Notch ligands Delta and Serrate, only the former was ...

Intraperitoneal melatonin is not neuroprotective in the G93ASOD1 transgenic mouse model of familial ALS and may exacerbate neurodegeneration
(2013)In amyotrophic lateral sclerosis (ALS) reactive oxygen species and apoptosis are implicated in disease pathogenesis. Melatonin with its anti-oxidant and anti-apoptotic properties is expected to ameliorate disease phenotype. ...

KIF1Bβ transports dendritically localized mRNPs in neurons and is recruited to synapses in an activity-dependent manner
(2013)KIF1Bβ is a kinesin-like, microtubule-based molecular motor protein involved in anterograde axonal vesicular transport in vertebrate and invertebrate neurons. Certain KIF1Bβ isoforms have been implicated in different forms ...

Article
KIF2β, a new kinesin superfamily protein in non-neuronal cells, is associated with lysosomes and may be implicated in their centrifugal translocation
(1998)Lysosomes concentrate juxtanuclearly in the region around the microtubule-organizing center by interaction with microtubules. Different experimental and physiological conditions can induce these organelles to move to the ...

Mutant polycystin-2 induces proliferation in primary rat tubular epithelial cells in a STAT-1/p21-independent fashion accompanied instead by alterations in expression of p57KIP2 and Cdk2
(2008)Background. Autosomal Dominant Polycystic Kidney Disease (ADPKD) is characterized by the formation of multiple fluid-filled cysts that destroy the kidney architecture resulting in end-stage renal failure. Mutations in genes ...

Article
Neural hyperplasia induced by RNA interference with m4/mα gene activity
(2000)The E(spl) complex (E(spl)-C) contains three different classes of genes that are downstream of Notch signaling. The bHLH genes mediate the Notch signal by repressing proneural gene activity, for example during the ...

Neural network controlling feeding in Lymnaea stagnalis: Immunocytochemical localization of myomodulin, small cardioactive peptide, buccalin, and FMRFamide‐ related peptides
(1994)This paper investigates the distribution of four classes of neuropeptides, myomodulin, small cardioactive peptide (SCP), buccalin, and FMRFamide, in central neurons forming the network that underlies feeding behavior in ...

Article
New compstatin peptides containing n-terminal extensions and non-natural amino acids exhibit potent complement inhibition and improved solubility characteristics
(2015)Compstatin peptides are complement inhibitors that bind and inhibit cleavage of complement C3. Peptide binding is enhanced by hydrophobic interactions

New Insights for Ets2 Function in Trophoblast using Lentivirus-Mediated Gene Knockdown in Trophoblast Stem Cells
(2010)Mouse trophoblast stem (TS) cells represent a unique in vitro system that provides an unlimited supply of TS cells for the study of trophoblast differentiation and TS cell self-renewal. Although the mouse transcription ...

Novel spatiotemporal glycome changes in the murine placenta during placentation based on BS-I lectin binding patterns
(2013)Although spatiotemporal changes of the glycome (full set of glycans, otherwise known as saccharides or carbohydrates) during placenta formation (placentation) are functionally and clinically important, they are poorly ...

The nucleotide-binding proteins Nubp1 and Nubp2 are negative regulators of ciliogenesis
(2014)Nucleotide-binding proteins Nubp1 and Nubp2 are MRP/MinD-type P-loop NTPases with sequence similarity to bacterial division site-determining proteins and are conserved, essential proteins throughout the Eukaryotes. They ...

A p53-mediated DNA damage response limits reprogramming to ensure iPS cell genomic integrity
(2009)The reprogramming of differentiated cells to pluripotent cells (induced pluripotent stem (iPS) cells) is known to be an inefficient process. We recently reported that cells with short telomeres cannot be reprogrammed to ...
