Post-transcriptional control of gene expression during mouse oogenesis.
Post-transcriptional mechanisms play a central role in regulating gene expression during oogenesis and early embryogenesis. Growing oocytes accumulate an enormous quantity of messenger RNAs (mRNAs), but transcription decreases dramatically near the end of growth and is undetectable during meiotic maturation. Following fertilization, the embryo is initially transcriptionally inactive and then be...
متن کاملExpression of growth hormone gene during early development of Siberian sturgeon (Acipenser baerii)
The mRNA expression of growth hormone (GH) gene in early development stages of Siberian sturgeon was investigated using RT-PCR method. Samples were collected from unfertilized eggs up to 50 days post hatched (dph) larvae in 11 different times. Ribosomal protein L6 (RPL6) transcripts were used as the internal standard during quantification of GH mRNA expression. The results showed that the GH mR...
متن کاملStage-specific regulation of programmed cell death during oogenesis of the medfly Ceratitis capitata (Diptera, Tephritidae).
In the present study, we describe novel features of programmed cell death in developing egg chambers occurring during mid- and late-oogenesis of the medfly Ceratitis capitata. During mid-oogenesis, the spontaneously degenerated egg chambers exhibit typical characteristics of apoptotic cell death. Their nurse cells contain fragmented DNA and fragmented actin, as revealed by TUNEL assay and immun...
متن کاملPatterns of mitochondrial gene expression in rapeseed leaves (Brassica napus L.) at early growth stage in response to drought stress
Drought stress adversely affects a plant’s growth and productivity. Wide ranges of molecular disorders could be caused by the production of reactive oxygen radicals. Plant cells have developed potential systems to prevent such damage by scavenging and reducing the reactive oxygen species (ROS). In this study, both the genotypes of oilseed rape-tolerant and sensitive to drought-were exposed to p...
متن کاملGenomic function during the lampbrush chromosome stage of amphibian oogenesis.
Throughout its lengthy developmental history the disposition of the genetic material in the amphibian o6cyte nucleus differs from that in other cell types. The chromosomes in the o6cyte nucleus, arrested for the whole of oogenesis at the prophase of the first meiotic division, are known to contain at least the tetraploid amount of DNA." 2 Odgenesis in amphibia requires months or even years to c...
