Uterine infection is one of the reproductive diseases that can have disturbing postpartum uterine health in cattle. Therefore, identification of resistant genotypes to uterine infection is important. Lactoferrin (LF) is one of the major antimicrobial compounds in the normal uterine discharges of cows. We hypothesized that allelic diversity in LF gene may contribute to susceptibility or resistan...

We have previously reported that human ACAT1 mRNAs produce the 50 kDa protein using the AUG(11397-1399) initiation codon, and also a minor 56 kDa isoform using the upstream in-frame GGC(1274-1276) initiation codon. The GGC(1274-1276) codon is located at the optional long 5'-untranslated region (5'-UTR, nt 1-1396) of the mRNAs. The DNA sequences corresponding to this 5'-UTR are located in two di...

Present studies demonstrate that treatment with arsenic trioxide (AT) lowered ectopically expressed or endogenous levels of Bcr-Abl protein, as well as induced apoptosis of Bcr-Abl-expressing cultured and primary chronic myeloid leukemia cells, including those refractory to imatinib mesylate. Treatment with AT neither affected bcr-abl mRNA transcript levels nor promoted the proteasomal degradat...

Regulatory relationships of 686 intronic miRNA and 784 intergenic miRNAs with mRNAs of 51 intronic miRNA coding genes were established. Interaction features of studied miRNAs with 5'UTR, CDS and 3'UTR of mRNA of each gene were revealed. Functional regions of mRNA were shown to be significantly heterogenous according to the number of binding sites of miRNA and to the location density of these si...

Translation Initiator of Short 5' UTR (TISU) is a unique regulatory element of both transcription and translation initiation. It is present in a sizable number of genes with basic cellular functions and a very short untranslated region (5' UTR). Here, we investigated translation initiation from short 5' UTR mRNAs with AUG in various contexts. Reducing 5' UTR length to the minimal functional siz...

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...

The translation efficiency of an mRNA molecule is typically determined by its 5'- and/or 3'-untranslated regions (UTRs). Previously, we have found that the 3'-UTR of Turnip yellow mosaic virus (TYMV) RNA enhances translation synergistically with a 5' cap. Here, we use a luciferase reporter system in cowpea protoplasts to show that the 5' 217 nucleotides from TYMV genomic RNA enhance expression ...
