    Intravital deep-tumor single-beam 3-photon, 4-photon, and harmonic microscopy

    Gert-Jan Bakker, Sarah Weischer ... Peter Friedl
    Infrared high-pulse-energy low-pulse-repetition-rate excitation advances deep intravital microscopy in strongly scattering tissues such as skin tumors and thick bone, thereby bringing previously inaccessible tumor areas in reach with subcellular resolution.

    Repression of hypoxia-inducible factor-1 contributes to increased mitochondrial reactive oxygen species production in diabetes

    Xiaowei Zheng, Sampath Narayanan ... Sergiu-Bogdan Catrina
    The repression of HIF-1 plays a central role in mitochondrial reactive oxygen species (ROS) overproduction and subsequent tissue damage in diabetes, which is mediated by increased mitochondrial respiration, making HIF-1 signaling an attractive therapeutic target for diabetes complications.

    Novel mechanistic insights into the role of Mer2 as the keystone of meiotic DNA break formation

    Dorota Rousová, Vaishnavi Nivsarkar ... John R Weir
    Mer2 interacts directly with meiotic chromatin, axial proteins, and the DNA break forming machinery to facilitate the formation of meiotic double-strand breaks.

    Mapping dopaminergic projections in the human brain with resting-state fMRI

    Marianne Oldehinkel, Alberto Llera ... Christian F Beckmann
    A functional connectivity gradient in striatum is obtained that maps onto DaT SPECT-derived dopaminergic projections and thereby likely provides a new biomarker for investigating dopaminergic (dys)function in the human brain.

    Multiomic characterization of pancreatic cancer-associated macrophage polarization reveals deregulated metabolic programs driven by the GM-CSF–PI3K pathway

    Seth Boyer, Ho-Joon Lee ... Costas A Lyssiotis
    A multiomics, systems biology approach was used to define the metabolic and signaling programs that drive the fate and function of pancreatic tumor-associated macrophages.

    VTA-projecting cerebellar neurons mediate stress-dependent depression-like behaviors

    Soo Ji Baek, Jin Sung Park ... Keiko Tanaka-Yamamoto
    Long-term chemogenetic manipulation of specific cerebellar pathway involving ventral tegmental area revealed a critical role of the pathway as a proactive mediator of the stress-dependent development of depression-like behaviors.

    Three-dimensional multi-site random access photostimulation (3D-MAP)

    Yi Xue, Laura Waller ... Nicolas Pégard
    A one-photon three-dimensional light sculpture technique has been developed and demonstrated for high spatio-temporal resolution photostimulation and imaging of dozens of neurons in the intact mouse brain in vivo.

    Simultaneous brain, brainstem, and spinal cord pharmacological-fMRI reveals involvement of an endogenous opioid network in attentional analgesia

    Valeria Oliva, Ron Hartley-Davies ... Jonathan CW Brooks
    Attention-grabbing tasks produce rapid opioid-mediated analgesia via the descending pain modulation network to alter spinal neuronal activity.

    Topoisomerase VI is a chirally-selective, preferential DNA decatenase

    Shannon J McKie, Parth Rakesh Desai ... Keir C Neuman
    Topoisomerase VI selectively catalyzes strand passage of DNA molecules juxtaposed at close to a right angle, which explains the observed chiral-dependent activity and preferential DNA decatenation versus supercoil relaxation.

    Muscle systems and motility of early animals highlighted by cnidarians from the basal Cambrian

    Xing Wang, Jean Vannier ... Jian Han
    Exceptionally preserved small shelly fossils (SSFs) from the early Cambrian Kuanchuanpu Formation (535 million years ago) reveal the muscular system of ancient cnidarians.
