BRCA1 Supports XIST RNA Concentration on the Inactive X Chromosome
BRCA1, a breast and ovarian tumor suppressor, colocalizes with markers of the inactive X chromosome (Xi) on Xi in female somatic cells and associates with XIST RNA, as detected by chromatin… Expand

Mammalian ribosomal protein (rp) mRNAs are subject to translational control, as illustrated by their selective release from polyribosomes in growth-arrested cells and their underrepresentation in… Expand
SV40 T antigen interacts with Nbs1 to disrupt DNA replication control.
Nijmegen breakage syndrome (NBS) is characterized by radiation hypersensitivity, chromosomal instability, and predisposition to cancer. Nbs1, the NBS protein, forms a tight complex with Mre11 and… Expand
13 Translational Control of Ribosomal Protein mRNAs in Eukaryotes
Many complex processes that occur during normal growth, differentiation, development, or malignant transformation in eukaryotes involve regulation of ribosome biosynthesis. This organelle contains… Expand
The Expression of Poly(A)-binding Protein Gene Is Translationally Regulated in a Growth-dependent Fashion through a 5′-Terminal Oligopyrimidine Tract Motif*

Poly(A)-binding protein (PABP) is an important regulator of gene expression that has been implicated in control of translation initiation. Here we report the isolation and the initial structural and… Expand
Active localization of the retinoblastoma protein in chromatin and its response to S phase DNA damage.
The Rb protein suppresses development of an abnormal state of endoreduplication arising after S phase DNA damage. In diploid, S phase cells, the activity of protein phosphatase 2A (PP2A) licenses the… Expand
Vertebrate mRNAs with a 5'-terminal pyrimidine tract are candidates for translational repression in quiescent cells: characterization of the translational cis-regulatory element.
The translation of mammalian ribosomal protein (rp) mRNAs is selectively repressed in nongrowing cells. This response is mediated through a regulatory element residing in the 5' untranslated region… Expand
The 5' terminal oligopyrimidine tract confers translational control on TOP mRNAs in a cell type- and sequence context-dependent manner.
TOP mRNAs are vertebrate transcripts which contain a 5'terminal oligopyrimidine tract (5'TOP), encode for ribosomal proteins and elongation factors 1alpha and 2, and are candidates for… Expand
Overexpression of initiation factor eIF-4E does not relieve the translational repression of ribosomal protein mRNAs in quiescent cells.
Translation of ribosomal protein (rp) mRNA is selectively repressed in mouse erythroleukemia (MEL) cells, which cease to proliferate upon differentiation, and in NIH 3T3 cells, for which growth is… Expand
Schistosomal MicroRNAs Isolated From Extracellular Vesicles in Sera of Infected Patients: A New Tool for Diagnosis and Follow-up of Human Schistosomiasis

Background Schistosomiasis traditionally has been diagnosed by detecting eggs in stool or urine. However, the sensitivity of these examinations is limited, especially in travelers with a low worm… Expand
