    The sexual identity of adult intestinal stem cells controls organ size and plasticity.

    , Nature, Vol: 530, Pages: 344-348, ISSN: 1476-4687

    Sex differences in physiology and disease susceptibility are commonly attributed to developmental and/or hormonal factors, but there is increasing realization that cell-intrinsic mechanisms play important and persistent roles. Here we use the Drosophila melanogaster intestine to investigate the nature and importance of cellular sex in an adult somatic organ in vivo. We find that the adult intestinal epithelium is a cellular mosaic of different sex differentiation pathways, and displays extensive sex differences in expression of genes with roles in growth and metabolism. Cell-specific reversals of the sexual identity of adult intestinal stem cells uncovers the key role this identity has in controlling organ size, reproductive plasticity and response to genetically induced tumours. Unlike previous examples of sexually dimorphic somatic stem cell activity, the sex differences in intestinal stem cell behaviour arise from intrinsic mechanisms that control cell cycle duration and involve a new doublesex- and fruitless-independent branch of the sex differentiation pathway downstream of transformer. Together, our findings indicate that the plasticity of an adult somatic organ is reversibly controlled by its sexual identity, imparted by a new mechanism that may be active in more tissues than previously recognized.

    Nanoscale Thermometry and Temperature Measurement

    , RSC Nanoscience and Nanotechnology No. 38, Thermometry at the Nanoscale: Techniques and Selected Applications., Editors: Carlos, Palacio, Publisher: Royal Society of Chemistry, Pages: 3-22, ISBN: 9781849739047

    Nanoscale temperature measurement concerns the determination of temperature or temperature difference at the sub-micron scale. Applications where it is important to be able to measure local temperature at the nanoscale include microelectronics, optics, microfluidics, chemical reaction and biochemical processes, such as living cells and nano-medicine.

    Endocrine remodelling of the adult intestine sustains reproduction in Drosophila.

    , eLife, Vol: 4, ISSN: 2050-084X

    The production of offspring is energetically costly and relies on incompletely understood mechanisms that generate a positive energy balance. In mothers of many species, changes in key energy-associated internal organs are common yet poorly characterised functionally and mechanistically. In this study, we show that, in adult Drosophila females, the midgut is dramatically remodelled to enhance reproductive output. In contrast to extant models, organ remodelling does not occur in response to increased nutrient intake and/or offspring demands, but rather precedes them. With spatially and temporally directed manipulations, we identify juvenile hormone (JH) as an anticipatory endocrine signal released after mating. Acting through intestinal bHLH-PAS domain proteins Methoprene-tolerant (Met) and Germ cell-expressed (Gce), JH signals directly to intestinal progenitors to yield a larger organ, and adjusts gene expression and sterol regulatory element-binding protein (SREBP) activity in enterocytes to support increased lipid metabolism. Our findings identify a metabolically significant paradigm of adult somatic organ remodelling linking hormonal signals, epithelial plasticity, and reproductive output.
