Mitochondrial fission, associated with fatty acids oxidation, is fundamental for AgRP neuronal activity during negative energy balance and in regulating fasting- and/or ghrelin-induced feeding.
The function and distribution of kinesin motors on exocytotic vesicles is dissected and visualized through a combination of gene knockout experiments, high-resolution microscopy and advanced data analysis.
Yeast promoters can harbor multiple natural DNA variants that influence gene expression, interact genetically, evolve under negative selection, alter transcription factor motifs, and remain challenging to predict.
A trial of mitofusin activation shows neuron regeneration and phenotype reversal in vitro and in vivo in experimental Charcot–Marie–Tooth disease type 2A caused by mitofusin 2 mutations.
Cell cycle gating enables a temporal compartmentalization of negative vs positive feedback control processes, leading to differential responses to repetitive interferon stimulations.
When translation stops, cells require intracellular acidification to turn on the conserved heat shock response during stress, and stress-triggered acidification (common in eukaryotes) is adaptive, promoting cell and population fitness.
The major cytosolic yeast peroxiredoxin Tsa1 controls aging and H2O2-resistance by inhibiting protein kinase A through a conserved cysteine in the catalytic subunit activation loop and not by scavenging H2O2.
