However, very little is known about the abundance and distribution of many plant and animal taxa in this region. Bumble bees are a group of cold-adapted and high elevation insects that fulfil an important ecological and economical function as pollinators of wild and agricultural flowering plants and crops. The Himalayan mountain range provides ample suitable habitats for bumble bees. Systematic study of Himalayan bumble bees began a few decades ago and the main focus has centred on the western region, while the eastern part of the mountain range has received little attention and only a few species have been verified. During a three-year survey, more than 700 bumble bee specimens of 21 species were collected in Arunachal Pradesh, the largest of the north-eastern states of India. The material included a range of species that were previously known from a limited number of collected specimens, which highlights the unique character of the East Himalayan ecosystem. Our results are an important first step towards a future assessment of species distribution, threat, and conservation. Clear elevation patterns of species diversity were observed, which raise important questions about the functional adaptations that allow bumble bees to thrive in this particularly moist region in the East Himalaya.}, language = {en} } @article{DammertBraegelmannOlsenetal.2019, author = {Dammert, Marcel A. and Br{\"a}gelmann, Johannes and Olsen, Rachelle R. and B{\"o}hm, Stefanie and Monhasery, Niloufar and Whitney, Christopher P. and Chalishazar, Milind D. and Tumbrink, Hannah L. and Guthrie, Matthew R. and Klein, Sebastian and Ireland, Abbie S. and Ryan, Jeremy and Schmitt, Anna and Marx, Annika and Ozretić, Luka and Castiglione, Roberta and Lorenz, Carina and Jachimowicz, Ron D. and Wolf, Elmar and Thomas, Roman K. and Poirier, John T. and B{\"u}ttner, Reinhard and Sen, Triparna and Byers, Lauren A. and Reinhardt, H.

Thus, a detailed mapping of MYC-paralog-specific vulnerabilities may help to develop effective therapies for SCLC patients. Using a unique cellular CRISPR activation model, we uncover that, in contrast to MYCN and MYCL, MYC represses BCL2 transcription via interaction with MIZ1 and DNMT3a. The resulting lack of BCL2 expression promotes sensitivity to cell cycle control inhibition and dependency on MCL1. Furthermore, MYC activation leads to heightened apoptotic priming, intrinsic genotoxic stress and susceptibility to DNA damage checkpoint inhibitors. Finally, combined AURK and CHK1 inhibition substantially prolongs the survival of mice bearing MYC-driven SCLC beyond that of combination chemotherapy. These analyses uncover MYC-paralog-specific regulation of the apoptotic machinery with implications for genotype-based selection of targeted therapeutics in SCLC patients.}, language = {en} }
