Deducing the stage of origin of Wilms tumours from a developmental series of Wt1 mutants

Wilms’ tumours, paediatric kidney cancers, are the archetypal example of tumours caused through the disruption of normal development. In this study, Hohenstein and colleagues compare different nephron-specific Wt1-knockout mouse models, identifying the stage of origin of human WT1-mutant Wilms’ tumours.

Enolase 1 and PDIA3 regulate Wnt/β-catenin-driven trans-differentiation of murine alveolar epithelial cells

The alveolar epithelium represents a major site of tissue destruction during lung injury. Königshoff and colleagues conducted proteomics, expression analysis and functional studies in primary murine ATII cells and identified proteins involved in Wnt/β-catenin-driven alveolar epithelial plasticity in lung injury and repair. Read the paper here [OPEN ACCESS].

Ciliary adenylyl cyclases control the Hedgehog pathway

Protein kinase A (PKA) accumulates at the base of the cilium where it negatively regulates the Hedgehog pathway. Although PKA activity is essentially controlled by the cAMP produced by adenylyl cyclases, the influence of these enzymes on the Hh pathway remains unclear. Pons and colleagues show that ciliary adenylyl cyclases AC5 and AC6 respond to stimulatory and inhibitory GPCRs to control PKA and, hence, transduce the Hedgehog signal. Read the paper here.

Stk40 represses adipogenesis through translational control of CCAAT/enhancer-binding proteins

Stk40 is a putative serine/threonine kinase originally identified as an activator of the Erk1/2 signaling required for primitive endoderm differentiation from mouse ESCs, and later found to be important for mouse fetal lung maturation. Jin and colleagues now show that Stk40 also plays a role in repressing adipogenesis through inhibition of C/EBP protein translation. Read the paper here.

Multiple-stressor interactions influence embryo development rate in the American horseshoe crab

Fertilized eggs of the American horseshoe crab are buried in shallow nests above the high tide line, where they are exposed to variations in abiotic conditions during early development. Using a multiple-stressors approach, Julian and colleagues examined whether the rate of embryonic development in these animals is affected by exposure to temperature, salinity and oxygen. Their results show that multiple abiotic stressors can interact to affect the development rate in ways that cannot be predicted from the effects of the stressors in isolation. Read the paper here.

Cold adaptation overrides developmental regulation of sarcolipin expression in mice skeletal muscle

Sarcolipin plays an important role in muscle-based thermogenesis. Periasamy and colleagues show that it is abundantly expressed in neonatal mouse muscles and cold challenge prevents its developmental downregulation, indicating higher recruitment of muscle-based thermogenesis in neonates. Read the paper here.

Gender-bending alligators use ESR1

In crocodilian as well as several turtle species, the gender of offspring is determined by the temperature at which the eggs are exposed during a critical developmental window called the thermo-sensitive period. Hormones also contribute to this process, since exposure to estrogens feminizes alligators developing at a male-producing temperature, but the mechanisms behind this phenomenon remain elusive. Sarah Alderman highlights a recent paper by the lab of Louis Guillette Jr in Endocrinology, examining which of the two known estrogen receptos (ESCR1 and ESCR2) is responsible for this hormone-mediated switch from male to female alligators.

The group led by ICREA Research Professor Cayetano Gonzalez at IRB Barcelona, in collaboration with the group of Professor Giuliano Callaini from the University of Siena in Italy, has published a new study in Current Biology that contributes to understanding how cilia are assembled.

Many cells in our bodies present a small structure that looks like, and as a matter of fact works as an antenna, conveying to the cell information on the extracellular environment. They are called cilia (plural) or cilium (singular). Ciliated cells play essential functions in the human body. Thus, for instance, the monitoring of fluid flow in the kidney, the detection of hormones in the brain, or the senses of hearing and smell depend on specialised neurons equipped with chemo-sensory or mechano-sensory cilia. Moreover, besides sensing, beating cilia keep fluids in motion in many parts of our bodies and are critical for human health.

A cilium can be regarded as a long and thin protrusion of the cell membrane that contains microtubules. Ciliary microtubules are arranged in a typical radial symmetry that is conserved through evolution and is templated by a small organelle that sits at the base of the cilium, known as basal body. Most animal cells contain two basal body-like structures (centrioles), but only one of them can actually work as basal body. In human cells, this is always the centriole that is said to be the “mother” because it was assembled earlier than the other, called the “daughter” centriole.

One laboratory animal model used to investigate how cilia are assembled is the vinegar fly Drosophila melanogaster. The article by the Gonzalez’s group shows that in Drosophila, as in humans, basal body fate is also reserved to the mother centriole. Moreover, through genetic manipulations that are easily performed in flies, they have been able to get a glimpse into the molecular mechanism that governs this fundamental process.

They have found that removal of the daughter-centriole specific protein Centrobin (CNB) allows daughter centrioles to serve as basal bodies. Thus CNB-depleted neurons present two cilia, the standard, which is templated by the mother centriole and a second one templated by the daughter centriole from which CNB has been removed. Conversely, mother centrioles engineered to carry CNB cannot function as basal bodies and, therefore, neurons modified this way cannot assemble cilia.

In humans, the lack of cilia, or cilia that do not work well, are the cause of a long list of disorders, known as ciliopathies, which include polydactyly, obesity, respiratory dysfunction, hearing impairment, and many others. Basic research in model organisms like the vinegar fly is helping to understand the molecular details of cilium assembly, thus paving the way to applied research in this field.

The Stowers Institute for Medical Research has two openings for postdoctoral researchers to work on projects using the cave fish system (Astyanax mexicanus) to address questions about the genetic basis of adaptation to new and extreme environments, with a particular focus on metabolic evolution.

Candidates will use RNA-sequencing, whole genome sequencing, transgenics, and metabolomics to uncover the genetic basis and underlying mechanism of the impressive metabolic adaptations cavefish have acquired to survive in nutrient poor environments.

Qualified candidates should have a background in evolutionary genetics and bioinformatics or a background in ecological genetics.  Research may be field-based, lab-based, or both.  Researchers who integrate genome level data with studies of ecology and evolution are encouraged to apply

One of the positions will involve substantial field work (in the caves in Mexico) to link the ecological settings in the caves with the observed and studied phenotypes.

Another position will direct the bioinformatics of the genomics of non-model organisms, and will analyze and interpret data accordingly.  Experience in handling large-scale sequence data is essential.

The ideal candidate has a doctorate degree in bioinformatics, genomics, or a related field; strong command of UNIX and other programming languages; hands-on experience with genomic data; and an interest in pursuing research on emerging model organisms.  In addition, the successful candidate will have a strong background in analysis of genetic and genomic data (e.g., whole-genome resequencing, RAD genotyping, QTL mapping) and/or experimental developmental biology (e.g., manipulation of gene expression, transgenesis, genome editing), and an ability and willingness to work both independently and collaboratively in a team-oriented environment.  No previous experience working with fish is required.

To apply, please submit a cover letter that includes a short summary of interests, a CV, and the contact information of 2-3 professional references to nro@stowers.org

Deadline for applications is September 15, 2015.  The positions are available October 1, 2015 (start date is flexible).
