AIM To analyze the influence of the premature termination codon on mRNA transport and stability METHODS Chondrocyte mRNA was isolated from homozygous and heterozygous nanomelic 17-days old embryos and examined by RT-PCR analysis. To analyze aggrecan mRNA stability, mRNA synthesis was inhibited with DRB [5,6 dichloro-1-(-D-ribofuranosyl benzimidazole)], a specific inhibitor of RNA polymerase I...
The influenza A virus RNA-dependent RNA polymerase produces capped and polyadenylated mRNAs in the nucleus of infected cells that resemble mature cellular mRNAs, but are made by very different mechanisms. Furthermore, only two of the 10 viral protein-coding mRNAs are spliced: most are intronless, while two contain unremoved introns. The mechanism(s) by which any of these mRNAs are exported from...
Bovine vascular smooth muscle cells (SMC) express the urokinase-type plasminogen activator receptor (u-PAR) claimed to be important in cell invasion. Receptor numbers and affinity are regulated by thrombin and several other mitogens involved in SMC proliferation. We investigated the effects of these mitogens on u-PAR mRNA levels. On continuous thrombin stimulation the u-PAR message in SMC was 1...
BACKGROUND During cytoplasmic oocyte maturation, Ca(2+) currents are vital for regulating a broad range of physiological processes. Recent studies have demonstrated that DMSO and EG cause large transient increases in intracellular Ca(2+) in mouse oocytes. The CP used in vitrifying protocols also increases the intracellular calcium transient. The aim of this study is to evaluate the effects of v...
