Recognition and pairing of the correct 5' and 3' splice sites (ss) of a pre-mRNA are critical events that occur early during spliceosome assembly. Little is known about the spatial organization in early spliceosomal complexes of the U1 and U2 snRNPs, which together with several non-snRNP proteins, are involved in juxtapositioning the functional sites of the pre-mRNA. To better understand the mo...
RNA stability control and degradation are employed by cells to control gene expression and to adjust the level of protein synthesis in response to physiological needs. In all domains of life, mRNA decay can commence in the 5'-3' as well as in the 3'-5'-direction. Consequently, mechanisms are in place conferring protection on mRNAs at both ends. Upon deprotection, dedicated enzymes/enzyme comple...
Introduction: Previous studies have shown altered levels of n-3LCPUFA in the pathophysiologcal conditions such as preeclampsia .Also elevated expression of sFlt-1 in preeclampsia plays a major role in the pathogenesis of this serious disorder especially in reduced placental oxygenation. The present study examines the hypothesis that Eicosapentaenoic acid (EPA 20:5), an omega-3 long-chain polyun...
Phytoene synthase (Psy) and Phytoene desaturase (Pds) are the first two regulatory enzymes in the carotenoids biosynthetic pathway. The genes Psy and Pds are under transcriptional control in many photosynthetic organisms. In the present study, using quantitative real time- PCR (qRT-PCR), the effects of uncoated and gum-Arabic coated PbS nanoparticles (GA-coated PbS NPs) and light intensity on t...
