  • A model is presented in which zebrafish atoh1 genes operate in a complex network leading to hair cell development. (tamu.edu)
  • The Clinical Significance of Dickkopf Wnt Signaling Pathway Inhibitor Gene Family in Head and Neck Squamous Cell Carcinoma. (nih.gov)
  • Here we show that bivalent domains and chromosome architecture for bivalent genes are dynamically regulated during the cell cycle in human pluripotent cells. (researchgate.net)
  • Central to this is the transient increase in H3K4-trimethylation at developmental genes during G1, thereby creating a 'window of opportunity' for cell-fate specification. (researchgate.net)
  • Transcript abundance of the genes causing the increase in cell wall thickness was measured in cultures established under different plant hormone compositions. (usda.gov)
  • Regarding animal models in ASD, many studies focus on gene expression, cortical neuronal migration and cell maturation, and neural network deficits. (bvsalud.org)
  • However, the principles that determine if a gene is regulated by miRNAs are poorly understood. (frontiersin.org)
  • Isolation of the murine Nbr1 gene adjacent to the murine Brca1 gene. (nih.gov)
  • In addition, selective and precise allocation of retinoic acid during early development through the interaction of Phase I enzymes throws the switch 'ON' in a predictable, developmental manner. (duke.edu)
  • When SRIF mRNA levels from each stage of development were quantified and normalized by the amount of poly (A) + RNA present at that stage of development, a unique pattern of SRIF gene expression was seen in each region. (northwestern.edu)
  • However, it remains unclear whether such a relationship is a universal feature of malignancy, whether heterogeneities exist in the developmental component of different tumor types and to which degree the resemblance between cancer and development is a tissue-specific phenomenon. (jax.org)
  • Finally, we identify a set of genes that are upregulated in most cancers and we show that this signature is active in early development. (jax.org)
  • Taken together, there appears to be a critical window during development where, outside factors that alter epigenetic programming can have lasting effects on neuronal gene expression. (uky.edu)
  • Phytohormone regulation of cotton fiber development in vitro. (usda.gov)
  • This approach will identify specific genes that are critical for initiating fiber development. (usda.gov)
  • Our team is interested in the regulation of two time points in cotton fiber development: initiation of fiber growth from ovule epidermal cells and the transition from fiber elongation to secondary wall biogenesis. (usda.gov)
  • Analysis of gene expression in a developmental context emphasizes dist" by K Naxerova, C J. Bult et al. (jax.org)
  • Finally, we show that disrupting the TET1-OGT interaction in mouse embryonic stem cells changes the abundance of TET2 and 5-methylcytosine, which is accompanied by alterations in gene expression. (zfin.org)
  • This study explores the use of a simple human neurosphere-based in vitro model to characterise the pharmacological and toxicological effects of LiCl and VPA using gene expression changes linked to phenotypic alterations in cells. (plos.org)
  • It is generally thought that such 'developmental programming' of diabetes risk is mediated, at least in part, by induced alterations in developmental epigenetics. (usda.gov)
