A framework for integrating the songbird brain.
(J Comp Physiol A Neuroethol Sens Neural Behav Physiol, 2002-12)Biological systems by default involve complex components with complex relationships. To decipher how biological systems work, we assume that one needs to integrate information over multiple levels of complexity. The songbird ... -
A Functionally Conserved Gene Regulatory Network Module Governing Olfactory Neuron Diversity.
(PLoS Genet, 2016-01)Sensory neuron diversity is required for organisms to decipher complex environmental cues. In Drosophila, the olfactory environment is detected by 50 different olfactory receptor neuron (ORN) classes that are clustered in ... -
A switch in the control of growth of the wing imaginal disks of Manduca sexta.
(PLoS One, 2010-05-19)BACKGROUND: Insulin and ecdysone are the key extrinsic regulators of growth for the wing imaginal disks of insects. In vitro tissue culture studies have shown that these two growth regulators act synergistically: either ... -
Across the meiotic divide - CSF activity in the post-Emi2/XErp1 era.
(J Cell Sci, 2008-11-01)Vertebrate eggs are arrested at the metaphase stage of meiosis II. Only upon fertilization will the metaphase-II-arrested eggs exit meiosis II and enter interphase. In 1971, Masui and Markert injected egg extracts into a ... -
Arterial pole progenitors interpret opposing FGF/BMP signals to proliferate or differentiate.
(Development, 2010-09)During heart development, a subpopulation of cells in the heart field maintains cardiac potential over several days of development and forms the myocardium and smooth muscle of the arterial pole. Using clonal and explant ... -
Automatic annotation of spatial expression patterns via sparse Bayesian factor models.
(PLoS Comput Biol, 2011-07)Advances in reporters for gene expression have made it possible to document and quantify expression patterns in 2D-4D. In contrast to microarrays, which provide data for many genes but averaged and/or at low resolution, ... -
BMP signaling in the development of the mouse esophagus and forestomach.
(Development, 2010-12)The stratification and differentiation of the epidermis are known to involve the precise control of multiple signaling pathways. By contrast, little is known about the development of the mouse esophagus and forestomach, ... -
Comparison of pattern detection methods in microarray time series of the segmentation clock.
(PLoS One, 2008-08-06)While genome-wide gene expression data are generated at an increasing rate, the repertoire of approaches for pattern discovery in these data is still limited. Identifying subtle patterns of interest in large amounts of data ... -
Cytoplasmic inheritance redux.
(Adv Child Dev Behav, 2013)Since the early twentieth century, inheritance was seen as the inheritance of genes. Concurrent with the acceptance of the genetic theory of inheritance was the rejection of the idea that the cytoplasm of the oocyte could ... -
dbl-1/TGF-β and daf-12/NHR Signaling Mediate Cell-Nonautonomous Effects of daf-16/FOXO on Starvation-Induced Developmental Arrest.
(PLoS Genet, 2015-12)Nutrient availability has profound influence on development. In the nematode C. elegans, nutrient availability governs post-embryonic development. L1-stage larvae remain in a state of developmental arrest after hatching ... -
Differential expression of glutamate receptors in avian neural pathways for learned vocalization.
(J Comp Neurol, 2004-08-09)Learned vocalization, the substrate for human language, is a rare trait. It is found in three distantly related groups of birds-parrots, hummingbirds, and songbirds. These three groups contain cerebral vocal nuclei for learned ... -
Examination of Endogenous Rotund Expression and Function in Developing Drosophila Olfactory System Using CRISPR-Cas9-Mediated Protein Tagging.
(G3 (Bethesda), 2015-10-23)The zinc-finger protein Rotund (Rn) plays a critical role in controlling the development of the fly olfactory system. However, little is known about its molecular function in vivo. Here, we added protein tags to the rn locus ... -
Growth factor erv1-like modulates Drp1 to preserve mitochondrial dynamics and function in mouse embryonic stem cells.
(Mol Biol Cell, 2010-04-01)The relationship of mitochondrial dynamics and function to pluripotency are rather poorly understood aspects of stem cell biology. Here we show that growth factor erv1-like (Gfer) is involved in preserving mouse embryonic ... -
Heme Oxygenase-1/Carbon Monoxide System and Embryonic Stem Cell Differentiation and Maturation into Cardiomyocytes.
(Antioxid Redox Signal, 2016-03-01)AIMS: The differentiation of embryonic stem (ES) cells into energetically efficient cardiomyocytes contributes to functional cardiac repair and is envisioned to ameliorate progressive degenerative cardiac diseases. Advanced ... -
Identification of late larval stage developmental checkpoints in Caenorhabditis elegans regulated by insulin/IGF and steroid hormone signaling pathways.
(PLoS Genet, 2014-06)Organisms in the wild develop with varying food availability. During periods of nutritional scarcity, development may slow or arrest until conditions improve. The ability to modulate developmental programs in response to ... -
Mammalian genes induce partially reprogrammed pluripotent stem cells in non-mammalian vertebrate and invertebrate species.
(Elife, 2013-09-03)Cells are fundamental units of life, but little is known about evolution of cell states. Induced pluripotent stem cells (iPSCs) are once differentiated cells that have been re-programmed to an embryonic stem cell-like state, ... -
Molecular profiling of the developing avian telencephalon: regional timing and brain subdivision continuities.
(J Comp Neurol, 2013-11)In our companion study (Jarvis et al. [2013] J Comp Neurol. doi: 10.1002/cne.23404) we used quantitative brain molecular profiling to discover that distinct subdivisions in the avian pallium above and below the ventricle ... -
Nutritional control of mRNA isoform expression during developmental arrest and recovery in C. elegans.
(Genome Res, 2012-10)Nutrient availability profoundly influences gene expression. Many animal genes encode multiple transcript isoforms, yet the effect of nutrient availability on transcript isoform expression has not been studied in genome-wide ... -
Pairing of competitive and topologically distinct regulatory modules enhances patterned gene expression.
(Mol Syst Biol, 2008)Biological networks are inherently modular, yet little is known about how modules are assembled to enable coordinated and complex functions. We used RNAi and time series, whole-genome microarray analyses to systematically ... -
Palmitoyl acyltransferase, Zdhhc13, facilitates bone mass acquisition by regulating postnatal epiphyseal development and endochondral ossification: a mouse model.
(PLoS One, 2014)ZDHHC13 is a member of DHHC-containing palmitoyl acyltransferases (PATs) family of enzymes. It functions by post-translationally adding 16-carbon palmitate to proteins through a thioester linkage. We have previously shown ...
