A unique Malpighian tubule architecture in informs the evolutionary origins of systemic osmoregulation in beetles.

Proc Natl Acad Sci U S A 2021 Apr;118(14)

Department of Biology, Section for Cell and Neurobiology, University of Copenhagen, DK-2100 Copenhagen, Denmark;

Maintaining internal salt and water balance in response to fluctuating external conditions is essential for animal survival. This is particularly true for insects as their high surface-to-volume ratio makes them highly susceptible to osmotic stress. However, the cellular and hormonal mechanisms that mediate the systemic control of osmotic homeostasis in beetles (Coleoptera), the largest group of insects, remain largely unidentified. Read More

A conserved role for arrow in posterior axis patterning across Arthropoda.

Dev Biol 2021 Feb 16;475:91-105. Epub 2021 Feb 16.

Department of Integrative Biology, University of Wisconsin-Madison, Madison, WI, USA 53706. Electronic address:

Segmentation is a key characteristic of Arthropoda that is linked to the evolutionary success of this lineage. It has previously been shown in both vertebrates and short germ insects that posterior segmentation requires canonical Wnt (cWnt) signaling, which maintains the expression of Caudal and the posterior growth zone; disruption of cWnt signaling incurs posterior truncations in these lineages due to the loss of the tail bud. However, comparable datasets for Wnt signaling are limited outside of holometabolous insects, due to incomparable phenotypic spectra and inefficacy of gene misexpression methods in certain model species.

Monell Chemical Senses Center, Philadelphia, PA 19104

Taste bud cells regenerate throughout life. Taste bud maintenance depends on continuous replacement of senescent taste cells with new ones generated by adult taste stem cells. More than a century ago it was shown that taste buds degenerate after their innervating nerves are transected and that they are not restored until after reinnervation by distant gustatory ganglion neurons.

Department of Microbiology, University of Georgia, Athens, GA, United States.

is commonly associated with venereal disease and abortions in cattle and sheep, and can also cause intestinal or systemic infections in humans that are immunocompromised, elderly, or exposed to infected livestock. It is also believed that infection can result from the consumption or handling of contaminated food products, but is rarely detected in food since isolation methods are not suited for its detection and the physiology of the organism makes culturing difficult. In the related species, , the ability to colonize the host has been linked to N-linked protein glycosylation with quantitative proteomics demonstrating that glycosylation is interconnected with cell physiology.

A Zinc Cluster Transcription Factor Contributes to the Intrinsic Fluconazole Resistance of Candida auris.

mSphere 2020 04 22;5(2). Epub 2020 Apr 22.

Institut für Molekulare Infektionsbiologie, Universität Würzburg, Würzburg, Germany

The recently emerged pathogenic yeast is a major concern for human health, because it is easily transmissible, difficult to eradicate from hospitals, and highly drug resistant. Most isolates are resistant to the widely used antifungal drug fluconazole due to mutations in the target enzyme Erg11 and high activity of efflux pumps, such as Cdr1. In the well-studied, distantly related yeast , overexpression of drug efflux pumps also is a major mechanism of acquired fluconazole resistance and caused by gain-of-function mutations in the zinc cluster transcription factors Mrr1 and Tac1.

Institute for Biology and Saxon Incubator for Clinical Translation (SIKT), University of Leipzig, Philipp-Rosenthal-Str. 55, 04103 Leipzig, Germany; Life&Medical Sciences Institute (LIMES), University of Bonn, 53115 Bonn, Germany. Electronic address:

Identification of signals for systemic adaption of hormonal regulation would help to understand the crosstalk between cells and environmental cues contributing to growth, metabolic homeostasis and development. Physiological states are controlled by precise pulsatile hormonal release, including endocrine steroids in human and ecdysteroids in insects. We show in Drosophila that regulation of genes that control biosynthesis and signaling of the steroid hormone ecdysone, a central regulator of developmental progress, depends on the extracellular matrix protein Obstructor-A (Obst-A).
