    Episode 17: January 2015

    In this episode we hear about controlling sperm by optogenetics, hibernation, body clocks, enzyme structure, and a way to overcome stress-induced infertility.

    Glucose inhibits cardiac muscle maturation through nucleotide biosynthesis

    Haruko Nakano et al.
    During cardiogenesis, the major role of glucose is not the catabolic extraction of energy but the anabolic biosynthesis of nucleotides.
    1. Neuroscience

    Pedunculopontine glutamatergic neurons control spike patterning in substantia nigra dopaminergic neurons

    Daniel J Galtieri et al.
    Pedunculopontine neurons can evoke burst spiking in substantia nigra dopaminergic neurons without engaging a subtype of glutamate receptor previously thought to be necessary for this spiking mode.

    Age-dependent diastolic heart failure in an in vivo Drosophila model

    Matthew P Klassen et al.
    As in humans, Drosophila hearts are able to maintain contractile performance during healthy aging, but this maintenance is associated with an increased susceptibility to progressive dysrhythmias that can lead to fibrillatory arrest.
    1. Neuroscience

    A novel inhibitory nucleo-cortical circuit controls cerebellar Golgi cell activity

    Lea Ankri et al.
    The glycinergic neurons of the cerebellar nuclei project extensively to the cerebellar cortex and inhibit GABAergic Golgi cells.
    1. Neuroscience

    The retrotrapezoid nucleus neurons expressing Atoh1 and Phox2b are essential for the respiratory response to CO2

    Pierre-Louis Ruffault et al.
    The location of neurons responsible for increasing the breathing rate upon detecting elevated levels of CO2 in the blood has been pinpointed to the retrotrapezoid nucleus in the brainstem.

    Recurrent gain of function mutation in calcium channel CACNA1H causes early-onset hypertension with primary aldosteronism

    Ute I Scholl et al.
    A novel Mendelian disease featuring early-onset hypertension is caused by a recurrent gain of function mutation in CACNA1H, which encodes the voltage-gated calcium channel Cav3.2.
    1. Neuroscience

    Luqin-like RYamide peptides regulate food-evoked responses in C. elegans

    Hayao Ohno et al.
    Identification and functional characterization of C. elegans luqin-like arginine-tyrosine-NH2 (RYamide) peptides reveal their critical role in feeding-related processes.
    1. Neuroscience

    Distinct regulation of dopamine D2S and D2L autoreceptor signaling by calcium

    Stephanie C Gantz et al.
    The loss of calcium-dependent D2 autoreceptor desensitization caused by prior in vivo cocaine exposure may be conferred by an unexpected role of the D2L splice variant as an autoreceptor.
