Thus, single-cell analysis offers an unprecedented view of primary uveal melanoma heterogeneity, identifies bona fide biomarkers for metastatic cells in the primary tumor, and reveals targetable modules driving growth and metastasis formation. Significantly, our findings demonstrate that HES6 is a valid target to stop uveal melanoma progression.Ubiquitination by serving as a major degradation signal of proteins, but also by controlling protein functioning and localization, plays critical roles in most key cellular processes. Here, we show that MITF, the master transcription factor in melanocytes, controls ubiquitination in melanoma cells. We identified FBXO32, a component of the SCF E3 ligase complex as a new MITF target gene. FBXO32 favors melanoma cell migration, proliferation, and tumor development in vivo. Transcriptomic analysis shows that FBXO32 knockdown induces a global change in melanoma gene expression profile. These include the inhibition of CDK6 in agreement with an inhibition of cell proliferation and invasion upon FBXO32 silencing. Furthermore, proteomic analysis identifies SMARC4, a component of the chromatin remodeling complexes BAF/PBAF, as a FBXO32 partner. FBXO32 and SMARCA4 co-localize at loci regulated by FBXO32, such as CDK6 suggesting that FBXO32 controls transcription through the regulation of chromatin remodeling complex activity. FBXO32 and SMARCA4 are the components of a molecular cascade, linking MITF to epigenetics, in melanoma cells.The ongoing COVID-19 pandemic constitutes not only a danger for public health, but may also threaten civil liberties. Looking at the examples of recent events in Poland and Hungary, the authors argue that governments may misuse pandemic for their political advantage, thus endangering public health. Political decisions taken to stem the spread of pandemics should be limited and strictly proportionate to the situation.During a public health emergency, a government must balance public welfare, equity, individual rights, and democratic processes and norms. These goods may conflict. Although science has a role in informing wise policy, no empirical evidence or algorithm can determine how to balance competing goods under conditions of uncertainty. Especially in a crisis, it is crucial to have a broad and free conversation about public policy. Many countries are moving in the opposite direction. Sixty-one percent of governments have imposed at least some problematic restrictions on individual rights or democratic processes during the COVID-19 pandemic, and 17 have made substantial negative changes. The policies of Poland and Hungary reflect these global trends and continue these countries' recent histories of democratic erosion.

However, population genetic analyses have been hindered by the homogeneous genetic structure of the population and the lack of suitable tools for data analysis. We have used whole-genome sequencing to characterize reference specimens from various known wild populations. In parallel, we established a whole-genome sequencing data analysis pipeline for the population genetic analysis of nearly monoclonal genomes. Our results provide evidence for systematic genetic differences between geographically separated populations and illustrate the emerging differentiation of the marbled crayfish genome. We also used mark-recapture population size estimation in combination with genetic data to model the growth pattern of marbled crayfish populations. Our findings uncover evolutionary dynamics in the marbled crayfish genome over a very short evolutionary timescale and identify the rapid growth of marbled crayfish populations as an important factor for ecological monitoring.In
