Article
An isolate of human immunodeficiency virus type 1 originally classified as subtype I represents a complex mosaic comprising three different group M subtypes (A, G, and I)
(1998)Full-length reference clones and sequences are currently available for eight human immunodeficiency virus type 1 (HIV-1) group M subtypes (A through H), but none have been reported for subtypes I and J, which have only ...

Differential expression of the rat retinoid X receptor γ gene during skeletal muscle differentiation suggests a role in myogenesis
(1997)Even though previous studies have shown that transcripts encoding the murine retinoid X receptor γ (RXRγ) are present in skeletal muscle of mouse embryos and that cultured myoblasts are induced to differentiate upon retinoid ...

Spatially and temporally regulated α6 integrin cleavage during Xenopus laevis development
(2008)The α6 integrin is essential for early nervous system development in Xenopus laevis. We have previously reported a uPA cleaved form of integrin α6 (α6p), in invasive human prostate cancer tissue, whose presence correlates ...

Intestinal Stem Cells: A Decade of Intensive Research in Drosophila and the Road Ahead
(2017)Since the molecular characterization of Drosophila midgut progenitors in 2006, a few hundred articles studying fly intestinal stem cells have already been published. There was a relative lag phase in creating new knowledge ...

Overexpression of the m4 and mα genes of the E(spl)-Complex antagonizes Notch mediated lateral inhibition
(1999)Intercellular signalling mediated by Notch proteins is crucial to many cell fate decisions in metazoans. Its profound effects on cell fate and proliferation require that a complex set of responses involving positive and ...

FAK transduces extracellular forces that orient the mitotic spindle and control tissue morphogenesis
(2014)Spindle orientation is critical for proper morphogenesis of organs and tissues as well as for the maintenance of tissue morphology. Although significant progress has been made in understanding the mechanisms linking the ...

Hedgehog restricts its expression domain in the Drosophila wing
(2007)The stable subdivision of Drosophila limbs into anterior and posterior compartments is a consequence of asymmetrical signalling by Hedgehog (Hh), from the posterior to anterior cells. The activity of the homeodomain protein ...

Attenuation of drug-stimulated topoisomerase II-DNA cleavable complex formation in wild-type HL-60 cells treated with an intracellular calcium buffer is correlated with decreased cytotoxicity and site-specific hypophosphorylation of topoisomerase IIα
(1998)Topoisomerase II (topo II), an essential enzyme for cell viability, is also the target for clinically important anti-neoplastic agents that stimulate topo II-mediated DNA scission. The role of alterations in topo IIα ...

A dominant-negative provides new insights into FAK regulation and function in early embryonic morphogenesis
(2013)FAK is a non-receptor tyrosine kinase involved in a wide variety of biological processes and crucial for embryonic development. In this manuscript, we report the generation of a new FAK dominant negative (FF), composed of ...

Intein-mediated site-specific conjugation of Quantum Dots to proteins in vivo
(2009)We describe an intein based method to site-specifically conjugate Quantum Dots (QDs) to target proteins in vivo. This approach allows the covalent conjugation of any nanostructure and/or nanodevice to any protein and thus ...

Profiling early infection responses: Pseudomonas aeruginosa eludes host defenses by suppressing antimocrobial peptide gene expression
(2005)Insights into the host factors and mechanisms mediating the primary host responses after pathogen presentation remain limited, due in part to the complexity and genetic intractability of host systems. Here, we employ the ...

Neuralized Encodes a Peripheral Membrane Protein Involved in Delta Signaling and Endocytosis
(2001)Activation of the Notch (N) receptor involves an intracellular proteolytic step triggered by shedding of the extracellular N domain (N-EC) upon ligand interaction. The ligand Dl has been proposed to effect this N-EC shedding ...

Novobiocin- and Phorbol-12-myristate-13-acetate-induced Differentiation of Human Leukemia Cells Associated with a Reduction in Topoisomerase II Activity
(1989)Studies were conducted to determine the possible involvement of DNA topoisomerase II (Topo II) in the induction of differentiation in two human promyelocytic HL-60 leukemia cell variants that are either susceptible or ...

In vitro study on the antioxidant activity of a polyphenol-rich extract from pinus brutia bark and its fractions
(2013)A crude hydromethanolic extract from Pinus brutia bark and its fractions (diethyl ether, ethyl acetate, n-butanol, and aqueous fractions) were studied with regard to their phenolic content and antioxidant activities. The ...
