Temporal transcription factors determine circuit membership by permanently altering motor neuron-to-muscle synaptic partnerships

10/12/2020

How circuit wiring is specified is a key question in developmental neurobiology. Previously, using the Drosophila motor system as a model, Meng and colleagues found the classic temporal transcription factor Hunchback acts in NB7-1 neuronal stem cells to control the number of NB7-1 neuronal progeny form functional synapses on dorsal muscles (Meng et al., 2019). However, it is unknown to what extent control of motor neuron-to-muscle synaptic partnerships is a general feature of temporal transcription factors.

A new Developmental Cell paper by CMB graduate student Kasey Day overturns a longstanding view that the endocytic pathway in yeast mirrors that in mammalian cells. The authors systematically characterized the dynamics of the budding yeast endocytic pathway by tracking the movement of an internalized dye. This study from the 

Antibody trust fall fails

10/19/2018

New technology developed in the Ruthenburg lab exposes widely held assumptions about antibody specificity and the practices of Chromatin Immunoprecipitation (ChIP) to be highly flawed.  A recent Molecular Cell study led by undergraduate Rohan Shah and CMB graduate student Adrian Grzybowski, discovered that conventional methods for “validating antibodies” for use in ChIP display poor specificity.

In regulating regulate actomyosin cortical contractility, Rho minds the GAPs

10/19/2018

Pulsed contractility is a dynamic form of actomyosin contractility that underlies many different kinds of morphogenetic processes. In a new paper published in the Journal of Cell Biology, CMB graduate student John Michaux and colleagues in the Munro Lab combine multicolor live imaging, single molecule analysis, genetic manipulations and mathematical modeling to identify a core biochemical circuit for pulsed contractility in early C. elegans embryos.
