  • We also analyzed the CTCF gene for its mRNA and protein expression and DNA sequence, and we investigated correlations with methylation of H19(mat). (nih.gov)

  • However, all of them were generated using a random integration method with variable transgene expression levels and the introduction of selectable marker genes often raise biosafety concern. (g3journal.org)
  • Furthermore, this single-copy fat-1 gene supported satisfactory expression in a variety of tissues in F1 generation pigs. (g3journal.org)
  • We were particularly interested to analyze the consequences of acquired chromosomal aneuploidies with respect to modifications of gene expression profiles. (aacrjournals.org)
  • A relative gain or loss of a chromosome or chromosomal arm usually resulted in a statistically significant increase or decrease, respectively, in the average expression level of all of the genes on the chromosome. (aacrjournals.org)
  • 0.05), perhaps due to specific silencing of the pro-apoptotic promoter shifting p73 gene expression to the anti-apoptotic transcript. (biomedsearch.com)

  • Furthermore, apomictic F 1 RNAi transgenic plants with reduced PsASGR-BBML expression had reduced parthenogenic embryo development and transgenic sexual pearl millet plants expressing P. squamulatum PsASGR-BBML genes were induced to produce haploid offspring [ 10 ]. (biomedcentral.com)
