ADAMTS1 (a disintegrin and metalloproteinase with thrombospondin motifs 1) is an inflammatory-induced gene. We have previously reported that ADAMTS1 was strongly but transiently expressed in the infarcted heart. In this study, we investigated whether a 3'-untranslated region (UTR) affects the mRNA stability of this gene. When stimulated with tissue necrosis factor (TNF)-alpha, the expression le...

The 3' untranslated region (3'UTR) of hepatitis C virus (HCV) messenger RNA stimulates viral translation by an undetermined mechanism. We identified a high affinity interaction, conserved among different HCV genotypes, between the HCV 3'UTR and the host ribosome. The 3'UTR interacts with 40S ribosomal subunit proteins residing primarily in a localized region on the 40S solvent-accessible surfac...

The effect of increasing the length of the 3'-untranslated region (UTR) on expression of luciferase mRNA was examined in transiently transfected carrot protoplasts. The effect of the 3'-UTR on both poly(A)- and poly(A)+ mRNA was examined. A nested set of constructs in which the 3'-UTR increased from 4 to 104 bases was generated by the introduction and reiteration of a 20 base sequence downstrea...

In some teleost fish, primordial germ cells (PGCs) inherit specific maternal cytoplasmic factors such as vasa and nanos 1 (nos1) mRNA. It has been shown that the 3'untranslated regions (UTRs) of vasa and nos1 have critical roles for stabilization of these RNAs in zebrafish PGCs. In this study, to determine whether this role of the nos 1 3'UTR is conserved between teleost species, we injected ar...

BACKGROUND In recent years, avian influenza viruses (AIVs) have seriously threatened human health. Questions such as: why do AIVs infect humans?, how quickly can an AIV become pandemic?, and which virus is the most dangerous? cannot be sufficiently answered using current bioinformatic studies. METHOD Secondary structures and energies of representative 5'-untranslated region (UTR) of the HA ge...

RPCI-42 Bovine Bacterial Artificial Chromosome (BAC) library was screened with oligonucleotide sequences corresponding to specific elements of the 5 UTR sequence of bovine PC and to a region of the coding sequence. Two BACs that hybridized to all probes were selected for further analysis. A partial restriction map of the BACs was made with oligonucleotides corresponding to the coding region and...

Dysfunction of hepatocyte nuclear factor 4α (HNF4α) has been linked to maturity onset diabetes of the young (MODY1), diabetes type II and possibly to renal cell carcinoma (RCC). Whereas diabetes causing mutations are well known, there are no HNF4A mutations found in RCC. Since so far analyses have been constricted to the promoter and open reading frame of HNF4A, we performed a systematic analys...

the application of critical pedagogy in educational contexts has received adequate research attention over the last decades. the main focus of this strand of research has, however, been on raising awareness of the educators. nevertheless, little is known about the consequences of the violation of critical pedagogy principles from efl teacher trainers’ perspectives. to begin to address this gap ...
