Physical Mechanisms Shaping the Drosophila Dorsoventral Compartment Boundary

, 2012
SummaryBackgroundSeparating cells with distinct identities and fates by straight and sharp compartment boundaries is important for growth and pattern formation during animal development.

Failure of digit tip regeneration in the absence of Lmx1b suggests Lmx1b functions disparate from dorsoventral polarity

, 2023
Summary: Mammalian digit tip regeneration is linked to the presence of nail tissue, but a nail-explicit model is missing. Here, we report that nail-less double-ventral digits of ΔLARM1/2 mutants that lack limb-specific Lmx1b enhancers fail to regenerate.

Dorsoventral Patterning: A Serpin Pinned down at Last [PDF]

Current Biology, 2004
Dorsoventral patterning in Drosophila has long been known to involve a cascade of proteases, held in the inactive zymogen state prior to signaling. At long last, the prediction that a protease inhibitor is involved in this pathway has been shown to be true, with the identification of a serpin that plays a key part in Drosophila embryonic patterning.

Lzts2 Regulates Embryonic Cell Movements and Dorsoventral Patterning through Interaction with and Export of Nuclear beta-Catenin in Zebrafish

, 2011
Leucine zipper tumor suppressor 2 (Lzts2) functions in the development and progression of various tumors, but its activities in vertebrate embryogenesis remain unclear.

CNS midline cells contribute to maintenance of the initial dorsoventral patterning of the Drosophila ventral neuroectoderm

, 2018
Dorsoventral patterning of the Drosophila ventral neuroectoderm is established by the expression of three evolutionarily conserved homeodomain genes: ventral nervous system defective (vnd), intermediate neuroblasts defective (ind), and muscle segment ...

DmMyD88 controls dorsoventral patterning of the Drosophila embryo

, 2003
International audienceMyD88 is an adapter protein in the signal transduction pathway mediated by interleukin-1 (IL-1) and Toll-like receptors. A Drosophila homologue of MyD88 (DmMyD88) was recently shown to be required for the Toll-mediated immune ...

A gradient of frequency-dependent synaptic properties along the longitudinal hippocampal axis

BMC Neuroscience, 2017
Background The hippocampus is a functionally heterogeneous brain structure and specializations of the intrinsic neuronal network may crucially support the functional segregation along the longitudinal axis of the hippocampus.
