K channel blockers control glucagon secretion by distinct mechanisms: a direct stimulation of α-cells involving a [Ca] rise and an indirect inhibition mediated by somatostatin.

Mol Metab 2021 Jun 9:101268. Epub 2021 Jun 9.

Université Catholique de Louvain, Institut de Recherche Expérimentale et Clinique, Pôle d'Endocrinologie, Diabète et Nutrition, Brussels, Belgium. Electronic address:

Objective: Glucagon is secreted by pancreatic α-cells in response to hypoglycemia and its hyperglycemic effect helps to restore normal blood glucose. Insulin and somatostatin (SST) secretions from β- and δ-cells, respectively, are stimulated by glucose by mechanisms implicating an inhibition of their ATP-sensitive K (K) channels, leading to an increase in [Ca] that triggers exocytosis. Drugs that close K channels, such as sulfonylureas, are used to stimulate insulin release in type 2 diabetic patients. Read More

Phylogenomic Analysis Reveals Dispersal-Driven Speciation and Divergence with Gene Flow in Lesser Sunda Flying Lizards (Genus Draco).

Syst Biol 2021 Jun 12. Epub 2021 Jun 12.

Museum of Vertebrate Zoology and Department of Integrative Biology, University of California, Berkeley, CA 94720, USA.

The Lesser Sunda Archipelago offers exceptional potential as a model system for studying the dynamics of dispersal-driven diversification. The geographic proximity of the islands suggests the possibility for successful dispersal, but this is countered by the permanence of the marine barriers and extreme intervening currents that are expected to hinder gene flow. Phylogenetic and species delimitation analyses of flying lizards (genus Draco) using single mitochondrial genes, complete mitochondrial genomes, and exome-capture data sets identified 9-11 deeply divergent lineages including single-island endemics, lineages that span multiple islands, and parapatrically-distributed non-sister lineages on the larger islands.

Polarized endosome dynamics engage cytoplasmic Par-3 that recruits dynein during asymmetric cell division.

Sci Adv 2021 Jun 11;7(24). Epub 2021 Jun 11.

Department of Bioengineering and Therapeutic Sciences, University of California, San Francisco, San Francisco, CA 94143, USA.

In the developing embryos, the cortical polarity regulator Par-3 is critical for establishing Notch signaling asymmetry between daughter cells during asymmetric cell division (ACD). How cortically localized Par-3 establishes asymmetric Notch activity in the nucleus is not understood. Here, using in vivo time-lapse imaging of mitotic radial glia progenitors in the developing zebrafish forebrain, we uncover that during horizontal ACD along the anteroposterior embryonic axis, endosomes containing the Notch ligand DeltaD (Dld) move toward the cleavage plane and preferentially segregate into the posterior (subsequently basal) Notch daughter.
