Flow Cytometry data from: "The EMT transcription factor Zeb1 is essential for HSPC differentiation that acts synergistically with Zeb2 in fine-tuning hematopoietic lineage fidelity"
<p>Abstract:</p> <p>The Zeb2 transcription factor has been demonstrated to play important roles in hematopoiesis and leukemic transformation. Zeb1 is a close family member of Zeb2 but has remained more enigmatic concerning its roles in hematopoiesis. Here we show using conditional loss of function approaches and bone marrow reconstitution experiments that Zeb1 plays cell autonomous role in hematopoietic lineage differentiation, particularly as a positive regulator of monocyte development in addition to its previously reported important role in T-cell differentiation. Analysis of existing single cell RNAseq data of early hematopoiesis has revealed distinctive expression differences between Zeb1 and Zeb2 in HSPC differentiation with Zeb2 being more highly and broadly expressed that Zeb1 except at a key transition point (ST-HSCàMPP1) whereby Zeb1 appears to be the dominantly expressed family member. Inducible deletion of both Zeb1 and Zeb2 using a tamoxifen inducible Cre-mediated approach leads to acute bone marrow failure at this transition point with increased long-term and shortterm hematopoietic stem cell numbers and an accompanying decrease in all hematopoietic lineage differentiation. Bioinformatics analysis of RNAseq data has revealed that Zeb2 acts predominantly as a transcriptional repressor involved in restraining mature hematopoietic lineage gene expression programs from being expressed too early in hematopoietic stem and progenitor cells (HSPCs). Zeb1 appears to fine tune this repressive role during hematopoiesis to ensure hematopoietic lineage fidelity. Analysis of ROSA26 locus based transgenic models has revealed that Zeb1 as well as Zeb2 overexpression within the hematopoietic system can drive extramedullary hematopoiesis/splenomegaly and enhanced monocyte development. Finally, deletion of Zeb2 alone or Zeb1/2 together was found to enhance survival in secondary MLL-AF9 AML models attesting to the oncogenic role of Zeb1/2 in AML.</p> <p> </p> <p>Flow cytometric and Hematocrit analysis methods: </p> <p><br> Cells were stained with antibodies listed in the provided Supplemental Table (Antibodies.xlsx) according to the manufacturer guidelines.

Active nematics director and flow field data
<p>We conduct our experiments on the microtubule-kinesin active nematic system pioneered in Sanchez et al. 2012. The long rod-like MTs are bundled together via depletion interactions and are driven out of equilibrium by the action of kinesin-streptavidin motor protein complexes, which are units that induce relative motion utilizing ATP<br> as the energy source. Depletion forces also aid in driving the MT bundles to form bundles to the oil-water<br> fluid interface, where they execute self-sustained bending and buckling instabilities. The system is extensile,<br> which means that active stresses cause the MT bundles to extend in length and contract in width.</p> <p> </p> <p>To investigate the dynamics of defects in 2D flat space, we prepare the active nematic in a flow-cell setup<br> where the entire pool of ingredients is confined in a 2D sealed cell roughly 10 cm2 in area and 100 μm in<br> thickness. The lower surface of the cell is subjected to hydrophobic treatment (using Aquapel) and the<br> upper surface to hydrophilic treatment (using polyacrylamide coating) to enhance wetting by the respective<br> fluid phases. A fluorinated oil (HFE-7500 with surfactant E2K0660) forms the oil-phase, and the active MT<br> suspension forms the water-phase. We obtained purified tubulin monomers and kinesin–streptavidin motor<br> protein complexes from the Dogic Group at Brandeis University. The polymerization of tubulin to<br> MTs is performed in our lab before mixing with other biomaterials as per the protocols described in previous<br> works. The final active mix has 20% MTs by volume aided with 144μM ATP. The entire flow<br> cell is sealed by epoxy resin and centrifuged at 1000 RPM to accelerate the depletion mechanism to the<br> interface.</p> <p><br> We use confocal fluorescence microscopy for visualization. The MTs are labeled with AlexaFlour 647 dye<br> and illuminated at 633 nm; the excitation and emission peaks are at 651 nm and 667 nm, respectively. After<br> sample preparation and centrifugation, we wait for 15-20 minutes to allow for uniform depletion, and then<br> image at a constant framerate till the activity ceases. Typically, the MTs stay active for 6+ hours. Imaging<br> is done using 10× and 20× objectives to focus on regions with area on the order of mm2, away from the<br> edges of the flow cell. The imaging process results in a time series of 8-bit grayscale images, which are stored<br> as the raw data.</p> <p> </p> <p>For more information, see "Physically-informed data-driven modeling of active nematics" by Golden et al.</p>

Balancing selection at a wing pattern locus is associated with major shifts in genome-wide patterns of diversity and gene flow
<p>Selection shapes genetic diversity around target mutations, yet little is known about how selection on specific loci affects the genetic trajectories of populations, including their genome-wide patterns of diversity and demographic responses. Here we study the patterns of genetic variation and geographic structure in a neotropical butterfly, <em>Heliconius numata</em>, and its closely related allies in the so-called melpomene-silvaniform clade. <em>H. numata</em> is known to have evolved an inversion supergene which controls variation in wing patterns involved in mimicry associations with distinct groups of co-mimics. Butterflies show disassortative mate preferences and heterozygote advantage at this locus. We contrasted patterns of genetic diversity and structure 1) among extant polymorphic and monomorphic populations of <em>H. numata</em>, 2) between <em>H. numata</em> and its close relatives, and 3) between ancestral lineages. We show that <em>H. numata</em> populations which carry the inversions as a balanced polymorphism show markedly distinct patterns of diversity compared to all other taxa. They show the highest genetic diversity and effective population size estimates in the entire clade, as well as a low level of geographic structure and isolation by distance across the entire Amazon basin. By contrast, monomorphic populations of <em>H. numata</em> as well as its sister species and their ancestral lineages all show lower effective population sizes and genetic diversity, and higher levels of geographical structure across the continent. One hypothesis is that the large effective population size of polymorphic populations could be caused by the shift to a regime of balancing selection due to the genetic load and disassortative preferences associated with inversions. Testing this hypothesis with forward simulations supported the observation of increased diversity in populations with the supergene. Our results are consistent with the hypothesis that the formation of a supergene triggered a change in gene flow, causing a general increase in genetic diversity and the homogenisation of genomes at the continental scale.</p>
Portable two-filter dual-flow-loop 222Rn detector: stand-alone monitor and calibration transfer device
<p>Little overlap exists in the required capabilities of <sup>222</sup>Rn (radon) monitors for public health and atmospheric research. The former requires robust, compact, easily transportable instruments to characterise daily to yearly variability >100 Bq m<sup>−3</sup>, whereas the latter requires static instruments capable of characterising sub-hourly variability between 0.1 and 100 Bq m<sup>−3</sup>. Consequently, detector development has evolved independently for the two research communities, and while many radon measurements are being made world-wide, the full potential of this measurement network can't be realised because not all results are comparable. Development of a monitor that satisfies the primary needs of both measurement communities, including a calibration traceable to the International System of Units (SI), would constitute an important step toward (i) increasing the availability of radon measurements to both research communities, and (ii) providing a means to harmonize and compare radon measurements across the existing eclectic global network of radon detectors. To this end, we describe a prototype detector built by the Australian Nuclear Science and Technology Organisation (ANSTO), in collaboration with the EMPIR 19ENV01 <em>traceRadon</em> Project and Physikalisch-Technische Bundesanstalt (PTB). This two-filter dual-flow-loop radon monitor can be transported in a standard vehicle, fits in a 19<sup>′′</sup> instrument rack, has a 30 min temporal resolution, and a detection limit of ∼0.14 Bq m<sup>−3</sup>. It is capable of continuous, long-term, low-maintenance, low-power, indoor or outdoor monitoring with a high sensitivity and an uncertainty of ∼15 % at 1 Bq m<sup>−3</sup>. Furthermore, we demonstrate the successful transfer of an SI traceable calibration from this portable monitor to a 1500 L two-filter radon monitor under field conditions.</p>
