Bdelloid rotifers are microinvertebrates with unique characteristics: they have survived tens of millions years without sexual reproduction; withstand extreme desiccation by undergoing anhydrobiosis; and tolerate very high levels ionizing radiation. Recent evidence suggests that subtelomeric regions the bdelloid genome contain sequences originating from other organisms horizontal gene transfer (HGT), which some known to be transcribed. However, extent foreign expression plays a role in...
Abstract Background In animals, the biogenesis of some lipoprotein classes requires members ancient large lipid transfer protein (LLTP) superfamily, including cytosolic subunit microsomal triglyceride (MTP), vertebrate apolipoprotein B (apoB), vitellogenin (Vtg), and insect apolipophorin II/I precursor (apoLp-II/I). most oviparous species, Vtg, a glycolipoprotein, is main egg yolk protein. Results This report clarifies phylogenetic relationships LLTP superfamily classifies them into three...
Abstract Ovaries of the penaeid shrimp Penaeus semisulcatus in various stages oocyte development were incubated vitro with 14 C or 3 H leucine. Protein synthesis was measured by TCA precipitation and vitellin specific radioimmunoprecipitation. The proteins synthesized subjected to native SDS denaturative gel electrophoresis visualized fluorography. results led following conclusions: 1) found depend on concentration leucine culture media. 2) A relatively constant level observed ovaries...
Abstract Background Microscopic monogonont rotifers, including the euryhaline species Brachionus plicatilis , are typically found in water bodies where environmental factors restrict population growth to short periods lasting days or months. The survival of is ensured via production resting eggs that show a remarkable tolerance unfavorable conditions and remain viable for decades. aim this study was generate Expressed Sequence Tags (ESTs) molecular characterisation processes associated with...
The source of yolk proteins in crustacean ovaries has been the subject controversy for several decades, and both extraovarian intraovarian synthesized have implicated. To offer a new insight into relationship vitellogenin (VTG) vitellin (VT), comparison VTG ovarian VT marine shrimp Penaeus semisulcatus was performed at protein cDNA levels. Two cDNAs (7920 2068 nucleotides [nt]) were sequenced from ovary one nt) hepatopancreas. hepatopancreas similar to ovary. Although gene also found males,...
Abstract Background In oviparous vertebrates, including fish, vitellogenesis consists of highly regulated pathways involving 17β-estradiol (E2). Previous studies focused on a relatively small number hepatic expressed genes during vitellogenesis. This study aims to identify involved in and by E2, using zebrafish microarray gene expression profiling, provide information functional distinctive the liver vitellogenic female, as model fish. Results Genes associated with were revealed following...
Retinal is the main retinoid stored in oviparous eggs of fish, amphibians, and reptiles, reaching oocytes association with vitellogenins, yolk precursor proteins. During early presegmentation stages zebrafish embryos, retinal metabolized to retinoic acid (RA), which regulates genes involved cell proliferation, differentiation, tissue function therefore essential for normal embryonic development. While synthesis vitellogenin its regulation by 17β-estradiol (E(2)) were extensively...
