"Alternative" endocytic mechanisms exploited by pathogens: new avenues for therapeutic delivery? [PDF]

open access: yes, 2007
Some pathogens utilize unique routes to enter cells that may evade the intracellular barriers encountered by the typical clathrin-mediated endocytic pathway.

Different domains cooperate to target the human ribosomal L7a protein to the nucleus and to the nucleoli. [PDF]

open access: yes, 1997
The human ribosomal protein L7a is a component of the major ribosomal subunit. We transiently expressed in HeLa cells L7a-β-galactosidase fusion proteins and studied their subcellular localization by indirect immunofluorescence staining with anti-β ...

Reporter constructs with low background activity utilizing the cat gene [PDF]

open access: yes, 1992
Reporter plasmids utilizing the cat gene for the analysis of promoter and enhancer sequences in vertebrate cells, were constructed. These plasmids minimize the background of transcription derived from cryptic promoters or cryptic regulatory elements ...

Improved arteriogenesis with simultaneous skeletal muscle repair in ischemic tissue by SCL plus multipotent adult progenitor cell clones from peripheral blood [PDF]

open access: yes, 2004
Background: The CD34- murine stem cell line RM26 cloned from peripheral blood mononuclear cells has been shown to generate hematopoietic progeny in lethally irradiated animals.

SV40: A Human Pathogen? [PDF]

open access: yesDisease Markers, 2001
Over the past eight years an increasing number of investigators have found SV40 genomic sequences in a variety of human samples, both malignant and normal. Tumor types recurrently reported as SV40‐positive include choroid plexus neoplasms, ependymomas, osteosarcomas, and mesotheliomas.

The cationic region of Rhes mediates its interactions with specific Gβ subunits [PDF]

open access: yes, 2009
Ras homologue enriched in striatum (Rhes) is a small monomeric G protein which functions in a variety of cellular processes, including attenuation of G protein-coupled receptor (GPCR)signalling.

A hierarchical model of transcriptional dynamics allows robust estimation of transcription rates in populations of single cells with variable gene copy number [PDF]

open access: yes, 2013
Motivation: cis-regulatory DNA sequence elements, such as enhancers and silencers, function to control the spatial and temporal expression of their target genes.

Reversal of terminal differentiation and control of DNA replication [PDF]

open access: yes, 1993
DNA replication in mammalian cells occurs in discrete nuclear foci. Here we show that terminally differentiated myotubes can be induced to reenter S phase and show the same pattern of replication foci as cycling cells.

Cryptic transcripts from a ubiquitous plasmid origin of replication confound tests for cis-regulatory function. [PDF]

open access: yes, 2012
A vast amount of research on the regulation of gene expression has relied on plasmid reporter assays. In this study, we show that plasmids widely used for this purpose constitutively produce substantial amounts of RNA from a TATA-containing cryptic ...

YIPFα1A expression is regulated by multilayered molecular mechanisms

open access: yesFEBS Open Bio, EarlyView.
YIPFα1A, a five‐pass Golgi protein, is regulated at multiple layers. (1) Rare‐codon enrichment drives translation‐coupled mRNA decay. (2) A proximal 3′‐UTR element stabilizes mRNA. (3) A distal 3′‐UTR element included by alternate poly(A) site usage represses translation, which can be overridden by the proximal 3′‐UTR element.
