Abstract
Rhabdomyosarcoma accounts for roughly 1% of adult sarcomas, with pleomorphic rhabdomyosarcoma (PRMS) as the most common subtype. Survival outcomes remain poor for patients with PRMS, and little is known about the molecular drivers of this disease. To better characterize PRMS, we performed a broad array of genomic and immunostaining analyses on 25 patient samples. In terms of gene expression and methylation, PRMS clustered more closely with other complex karyotype sarcomas than with pediatric alveolar and embryonal rhabdomyosarcoma. Immune infiltrate levels in PRMS were among the highest observed in multiple sarcoma types and contrasted with low levels in other rhabdomyosarcoma subtypes. Lower immune infiltrate was associated with complete loss of both TP53 and RB1. This comprehensive characterization of the genetic, epigenetic, and immune landscape of PRMS provides a roadmap for improved prognostications and therapeutic exploration.

Abstract
Abstract
Patients with brain tumors and metastases have poor prognosis and overall survival rates despite the advancements in neurosurgery, radiotherapy, and chemotherapy. Genomic alterations in HER2 are present in brain metastases of breast cancer (BC; ~20%) and non-small cell lung cancer (NSCLC; 13-20%), and EGFR alterations occur frequently in glioblastoma multiforme (GBM; >50%). Despite the advancements in standard of care options, optimal treatment management for these patients remains an unmet medical need. Recent evidence suggests activity of systemic therapy for immune and targeted therapies in the brain, including agents targeting HER2/EGFR. HER2-targeted tyrosine kinase inhibitors lapatinib, neratinib, and tucatinib and the HER2-targeted antibodies trastuzumab and pertuzumab, in combination with chemotherapy, have been shown to improve survival of patients with HER2 overexpressing BC in the presence of brain metastases. The limited penetration of these compounds into the CNS, however, limits their efficacy. TAS2940 is an irreversible pan-ErbB inhibitor with greater brain-penetrability than poziotinib, tucatinib, and neratinib. Here, we demonstrate that TAS2940 induces downregulation of phosphorylated HER2/EGFR, reduces tumor burden, and promotes a significant increase in survival in intracranial xenograft mouse models with HER2-amplification (BC), HER2-Exon20 insertion mutation (NSCLC), and EGFR-amplification (GBM). These promising preclinical data highlight potential novel therapeutic strategies for patients with EGFR-aberrant GBM and brain metastases harboring HER2/EGFR alterations, and may help support the advancement of the ongoing first-in-human clinical trial (NCT04982926) for TAS2940 in solid tumors with EGFR and/or HER2 alterations.

Abstract
Treatment with therapy targeting BRAF and MEK (BRAF/MEK) has revolutionized care in melanoma and other cancers; however, therapeutic resistance is common and innovative treatment strategies are needed1,2. Here we studied a group of patients with melanoma who were treated with neoadjuvant BRAF/MEK-targeted therapy ( NCT02231775 , n = 51) and observed significantly higher rates of major pathological response (MPR; ≤10% viable tumour at resection) and improved recurrence-free survival (RFS) in female versus male patients (MPR, 66% versus 14%, P = 0.001; RFS, 64% versus 32% at 2 years, P = 0.021). The findings were validated in several additional cohorts2-4 of patients with unresectable metastatic melanoma who were treated with BRAF- and/or MEK-targeted therapy (n = 664 patients in total), demonstrating improved progression-free survival and overall survival in female versus male patients in several of these studies. Studies in preclinical models demonstrated significantly impaired anti-tumour activity in male versus female mice after BRAF/MEK-targeted therapy (P = 0.006), with significantly higher expression of the androgen receptor in tumours of male and female BRAF/MEK-treated mice versus the control (P = 0.0006 and P = 0.0025). Pharmacological inhibition of androgen receptor signalling improved responses to BRAF/MEK-targeted therapy in male and female mice (P = 0.018 and P = 0.003), whereas induction of androgen receptor signalling (through testosterone administration) was associated with a significantly impaired response to BRAF/MEK-targeted therapy in male and female patients (P = 0.021 and P < 0.0001). Together, these results have important implications for therapy.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer that has remained clinically challenging to manage. Here we employ an RNAi-based in vivo functional genomics platform to determine epigenetic vulnerabilities across a panel of patient-derived PDAC models. Through this, we identify protein arginine methyltransferase 1 (PRMT1) as a critical dependency required for PDAC maintenance. Genetic and pharmacological studies validate the role of PRMT1 in maintaining PDAC growth. Mechanistically, using proteomic and transcriptomic analyses, we demonstrate that global inhibition of asymmetric arginine methylation impairs RNA metabolism, which includes RNA splicing, alternative polyadenylation, and transcription termination. This triggers a robust downregulation of multiple pathways involved in the DNA damage response, thereby promoting genomic instability and inhibiting tumor growth. Taken together, our data support PRMT1 as a compelling target in PDAC and informs a mechanism-based translational strategy for future therapeutic development.Statement of significancePDAC is a highly lethal cancer with limited therapeutic options. This study identified and characterized PRMT1-dependent regulation of RNA metabolism and coordination of key cellular processes required for PDAC tumor growth, defining a mechanism-based translational hypothesis for PRMT1 inhibitors.

Abstract
Mitochondria control eukaryotic cell fate by producing the energy needed to support life and the signals required to execute programed cell death. The biochemical milieu is known to affect mitochondrial function and contribute to the dysfunctional mitochondrial phenotypes implicated in cancer and the morbidities of aging. However, the physical characteristics of the extracellular matrix are also altered in cancerous and aging tissues. Here, we demonstrate that cells sense the physical properties of the extracellular matrix and activate a mitochondrial stress response that adaptively tunes mitochondrial function via solute carrier family 9 member A1-dependent ion exchange and heat shock factor 1-dependent transcription. Overall, our data indicate that adhesion-mediated mechanosignaling may play an unappreciated role in the altered mitochondrial functions observed in aging and cancer.

Abstract
Abstract
Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal adult cancers with an average 5-year survival rate of less than 10% due in part to the limited number of effective therapies. Activation of TRAILR2 (Tumor necrosis factor (TNF)-Related Apoptosis-Inducing Ligand Receptor 2) has emerged as an important therapeutic concept in cancer treatment. Traditional TRAILR2 agonists have had limited clinical success due to lack of efficacy or, importantly, severe hepatotoxicity. Here we present anti-tumor activity in preclinical PDAC models for BI 905711, a first-in-class tetravalent bispecific antibody specifically designed to overcome the disadvantages of previous strategies targeting TRAILR2.
BI 905711 serves as a uniquely specific, and liver-sparing therapeutic by targeting tumors that co-express TRAILR2 and another cell surface protein CDH17, which has ~40% prevalence in PDAC and is not expressed in normal liver. Working from a large cohort of molecularly characterized PDAC PDX models, we provide the first preclinical evidence of BI 905711 exhibiting robust anti-tumor activity in difficult to treat PDAC PDX models. Anti-tumor efficacy in responding models correlated with strong induction of Caspases 3/7 and 8 activation in tumors 24 hours after a single dose of BI 905711, and was associated with the presence and expression levels of TRAILR2 and CDH17 proteins. Evaluation of models with differential TRAILR2 and CDH17 expression profiles helped define the expression threshold for each target that is associated with response, upon which clinical assay development is in process for future patient stratification. Additionally, response was also associated with PDAC molecular subtypes utilizing a novel proprietary gene co-expression network developed from a curated cohort of PDAC PDX tumors. Responders to BI 905711 were identified primarily within the classical and quasi-basal/hybrid subtypes when TRAILR2 was adequately co-expressed. This correlates with an enrichment pattern of CDH17 gene expression that is mostly within the classical gene cluster and strongly anti-correlated with basal-like cluster enrichment.
Robust preclinical anti-tumor activity of BI 905711 in TRAILR2 and CDH17-expressing PDAC PDX models, along with this antibody's potential for a favorable safety profile, has justified the enrollment of pancreatic cancer patients in the ongoing BI 905711 FIH Phase I clinical trial (NCT04137289).

Abstract
Abstract
The SOS1i::KRAS inhibitor BI 1701963 is the first direct RAS signaling modifier to enter phase I clinical trials both as a monotherapy as well as in combination. SOS1::KRAS inhibitors exhibit activity against a broad spectrum of KRAS alleles, including the major G12D/V/C and G13D oncoproteins, while sparing the interaction of KRAS with SOS2. Here, we present pre-clinical data showing enhanced pathway modulation and synergistic anti-tumor effects following vertical pathway inhibition of BI 1701963 in combination with mitogen-activated protein kinase inhibitors (MEKi; trametinib and BI 3011441) or KRAS G12C inhibitors (MRTX849 and BI 1823911). Furthermore, SOS1::KRAS inhibitor treatment sensitizes tumor cells to increased DNA damage in combination with irinotecan. Our results highlight the suitability of SOS1::KRAS inhibitors as a backbone in combination therapies targeting KRAS-dependent tumors. Pre-clinical combination data supported the start of multiple phase I trials investigating the safety, tolerability, recommended dose and preliminary efficacy of BI 1701963 alone and in combination with other anti-cancer agents. Combination trials of BI 1701963 with MEKi include cohorts of patients with KRAS mutant solid tumors, such as non-small cell lung cancer (NSCLC), colorectal cancer (CRC), cholangiocarcinoma and pancreatic adenocarcinoma. Trials exploring the combination of BI 1701963 with irreversible KRAS G12C inhibitors (MRTX849 and BI 1823911) will include cohorts of patients with KRAS G12C mutant NSCLC and CRC. In a further study, the combination of BI 1701963 with irinotecan is being evaluated in patients with KRAS mutant CRC. Primary endpoints include dose-limiting toxicities, treatment-emergent or -related adverse events. Secondary endpoints include pharmacokinetic and pharmacodynamic properties of combination regimens and preliminary efficacy.

Abstract
BACKGROUND & AIMS Understanding the mechanisms by which tumors adapt to therapy is critical for developing effective combination therapeutic approaches to improve clinical outcomes for patients with cancer. METHODS To identify promising and clinically actionable targets for managing colorectal cancer (CRC), we conducted a patient-centered functional genomics platform that includes approximately 200 genes and paired this with a high-throughput drug screen that includes 262 compounds in four patient-derived xenografts (PDXs) from patients with CRC. RESULTS Both screening methods identified exportin 1 (XPO1) inhibitors as drivers of DNA damage-induced lethality in CRC. Molecular characterization of the cellular response to XPO1 inhibition uncovered an adaptive mechanism that limited the duration of response in TP53-mutated, but not in TP53-wild-type CRC models. Comprehensive proteomic and transcriptomic characterization revealed that the ATM/ATR-CHK1/2 axes were selectively engaged in TP53-mutant CRC cells upon XPO1 inhibitor treatment and that this response was required for adapting to therapy and escaping cell death. Administration of KPT-8602, an XPO1 inhibitor, followed by AZD-6738, an ATR inhibitor, resulted in dramatic antitumor effects and prolonged survival in TP53-mutant models of CRC. CONCLUSIONS Our findings anticipate tremendous therapeutic benefit and support the further evaluation of XPO1 inhibitors, especially in combination with DNA damage checkpoint inhibitors, to elicit an enduring clinical response in patients with CRC harboring TP53 mutations.

Abstract
In multicellular organisms, neurons integrate a diverse array of external cues to affect downstream changes in organismal health. Specifically, activation of the endoplasmic reticulum (ER) unfolded protein response (UPRER) in neurons increases lifespan by preventing age-onset loss of ER proteostasis and driving lipid depletion in a cell non-autonomous manner. The mechanism of this communication is dependent on the release of small clear vesicles from neurons. We find dopaminergic neurons are necessary and sufficient for activation of cell non-autonomous UPRER to drive lipid depletion in peripheral tissues, whereas serotonergic neurons are sufficient to drive protein homeostasis in peripheral tissues. These signaling modalities are unique and independent and together coordinate the beneficial effects of neuronal cell non-autonomous ER stress signaling upon health and longevity.

Abstract
Longevity is dictated by a combination of environmental and genetic factors. One of the key mechanisms to regulate life-span extension is the induction of protein chaperones for protein homeostasis. Ectopic activation of the unfolded protein response of the endoplasmic reticulum (UPRER) specifically in neurons is sufficient to enhance organismal stress resistance and extend life span. Here, we find that this activation not only promotes chaperones but also facilitates ER restructuring and ER function. This restructuring is concomitant with lipid depletion through lipophagy. Activation of lipophagy is distinct from chaperone induction and is required for the life-span extension found in this paradigm. Last, we find that overexpression of the lipophagy component, ehbp-1, is sufficient to deplete lipids, remodel ER, and promote life span. Therefore, UPR induction in neurons triggers two distinct programs in the periphery: the proteostasis arm through protein chaperones and metabolic changes through lipid depletion mediated by EH domain binding protein 1 (EHBP-1).

Abstract
There are many studies suggesting an age-associated decline in the actin cytoskeleton, and this has been adopted as common knowledge in the field of aging biology. However, a direct identification of this phenomenon in aging multicellular organisms has not been performed. Here, we express LifeAct::mRuby in a tissue-specific manner to interrogate cytoskeletal organization as a function of age. We show for the first time in Caenorhabditis elegans that the organization and morphology of the actin cytoskeleton deteriorate at advanced age in the muscles, intestine, and hypodermis. Moreover, hsf-1 is essential for regulating cytoskeletal integrity during aging, so that knockdown of hsf-1 results in premature aging of actin and its overexpression protects actin cytoskeletal integrity in the muscles, the intestine, and the hypodermis. Finally, hsf-1 overexpression in neurons alone is sufficient to protect cytoskeletal integrity in nonneuronal cells.

Abstract
Healthy, functional mitochondria are central to many cellular and physiological phenomena, including aging, metabolism, and stress resistance. A key feature of healthy mitochondria is a high membrane potential (Δψ) or charge differential (i.e., proton gradient) between the matrix and inner mitochondrial membrane. Mitochondrial Δψ has been extensively characterized via flow cytometry of intact cells, which measures the average membrane potential within a cell. However, the characteristics of individual mitochondria differ dramatically even within a single cell, and thus interrogation of mitochondrial features at the organelle level is necessary to better understand and accurately measure heterogeneity. Here we describe a new flow cytometric methodology that enables the quantification and classification of mitochondrial subtypes (via their Δψ, size, and substructure) using the small animal model C. elegans. Future application of this methodology should allow research to discern the bioenergetic and mitochondrial component in a number of human disease and aging models, including, C. elegans, cultured cells, small animal models, and human biopsy samples. © 2018 by John Wiley & Sons, Inc.

Abstract
The tissue-specific etiology of aging and stress has been elusive due to limitations in data processing of current techniques. Despite that many techniques are high-throughput, they usually use singular features of the data (e.g. whole fluorescence). One technology at the nexus of fluorescence-based screens is large particle flow cytometry ("biosorter"), capable of recording positional fluorescence and object granularity information from many individual live animals. Current processing of biosorter data, however, do not integrate positional information into their analysis and data visualization. Here, we present a bioanalytical platform for the quantification of positional information ("longitudinal profiling") of C. elegans, which we posit embodies the benefits of both high-throughput screening and high-resolution microscopy. We show the use of these techniques in (1) characterizing distinct responses of a transcriptional reporter to various stresses in defined anatomical regions, (2) identifying regions of high mitochondrial membrane potential in live animals, (3) monitoring regional mitochondrial activity in aging models and during development, and (4) screening for regulators of muscle mitochondrial dynamics in a high-throughput format. This platform offers a significant improvement in the quality of high-throughput biosorter data analysis and visualization, opening new options for region-specific phenotypic screening of complex physiological phenomena and mitochondrial biology.

Abstract
The Drosophila melanogaster (Dmel) eye is an ideal model to study development, intracellular signaling, behavior, and neurodegenerative disease. Interestingly, dynamic data are not commonly employed to investigate eye-specific disease models. Using axonal transport of the morphogen Hedgehog (Hh), which is integral to Dmel eye-brain development and implicated in stem cell maintenance and neoplastic disease, we demonstrate the ability to comprehensively quantify and characterize its trafficking in various neuron types and a neurodegeneration model in live early third-instar larval Drosophila. We find that neuronal Hh, whose kinetics have not been reported previously, favors fast anterograde transport and varies in speed and flux with respect to axonal position. This suggests distinct trafficking pathways along the axon. Lastly, we report abnormal transport of Hh in an accepted model of photoreceptor neurodegeneration. As a technical complement to existing eye-specific disease models, we demonstrate the ability to directly visualize transport in real time in intact and live animals and track secreted cargoes from the axon to their release points. Particle dynamics can now be precisely calculated and we posit that this method could be conveniently applied to characterizing disease pathogenesis and genetic screening in other established models of neurodegeneration. Summary: A novel method to directly visualize Hedgehog transport in the photoreceptor neurons of living animals offers unprecedented positional and temporal detail of complex phenotypes in real time.

Abstract
The patterning activity of a morphogen depends on secretion and dispersal mechanisms that shape its distribution to the cells of a receptive field. In the case of the protein Hedgehog (Hh), these mechanisms of secretion and transmission remain unclear. In the developing Drosophila visual system, Hh is partitioned for release at opposite poles of photoreceptor neurons. Release into the retina regulates the progression of eye development; axon transport and release at axon termini trigger the development of postsynaptic neurons in the brain. Here we show that this binary targeting decision is controlled by a C-terminal proteolysis. Hh with an intact C-terminus undergoes axonal transport, whereas a C-terminal proteolysis enables Hh to remain in the retina, creating a balance between eye and brain development. Thus, we define a novel mechanism for the apical/basal targeting of this developmentally important protein and posit that similar post-translational regulation could underlie the polarity of related ligands.

Abstract
Mitochondrial bioenergetics has been implicated in a number of vital cellular and physiological phenomena, including aging, metabolism, and stress resistance. Heterogeneity of the mitochondrial membrane potential (Δψ), which is central to organismal bioenergetics, has been successfully measured via flow cytometry in whole cells but rarely in isolated mitochondria from large animal models. Similar studies in small animal models, such as Caenorhabditis elegans (C. elegans), are critical to our understanding of human health and disease but lack analytical methodologies. Here we report on new methodological developments that make it possible to investigate the heterogeneity of Δψ in C. elegans during development and in tissue-specific studies. The flow cytometry methodology described here required an improved collagenase-3-based mitochondrial isolation procedure and labeling of mitochondria with the ratiometric fluorescent probe JC-9. To demonstrate feasibility of tissue-specific studies, we used C. elegans strains expressing blue-fluorescent muscle-specific proteins, which enabled identification of muscle mitochondria among mitochondria from other tissues. This methodology made it possible to observe, for the first time, critical changes in Δψ during C. elegans larval development and provided direct evidence of the elevated bioenergetic status of muscle mitochondria relative to their counterparts in the rest of the organism. Further application of these methodologies can help tease apart bioenergetics and other biological complexities in C. elegans and other small animal models used to investigate human disease and aging.

Abstract
In mouse embryos at mid-gestation, primordial germ cells (PGCs) undergo licensing to become gametogenesis-competent cells (GCCs), gaining the capacity for meiotic initiation and sexual differentiation. GCCs then initiate either oogenesis or spermatogenesis in response to gonadal cues. Germ cell licensing has been considered to be a cell-autonomous and gonad-independent event, based on observations that some PGCs, having migrated not to the gonad but to the adrenal gland, nonetheless enter meiosis in a time frame parallel to ovarian germ cells -- and do so regardless of the sex of the embryo. Here we test the hypothesis that germ cell licensing is cell-autonomous by examining the fate of PGCs in Gata4 conditional mutant (Gata4 cKO) mouse embryos. Gata4, which is expressed only in somatic cells, is known to be required for genital ridge initiation. PGCs in Gata4 cKO mutants migrated to the area where the genital ridge, the precursor of the gonad, would ordinarily be formed. However, these germ cells did not undergo licensing and instead retained characteristics of PGCs. Our results indicate that licensing is not purely cell-autonomous but is induced by the somatic genital ridge. During embryonic development, stem cell-like primordial germ cells travel across the developing embryo to the genital ridge, which gives rise to the gonad. Around the time of their arrival, the primordial germ cells gain the capacity to undertake sexual specialization and meiosis—a process called germ cell licensing. Based on the observation that meiosis and sexual differentiation can occur when primordial germ cells stray into the area of the adrenal gland, the primordial germ cell has been thought to be responsible for its own licensing. We tested this notion by examining the licensing process in mutant mouse embryos that did not form a genital ridge. We discovered that in the absence of the genital ridge, primordial germ cells migrate across the developing embryo properly, but instead of undergoing licensing, these cells retain their primordial germ cell characteristics. We conclude that licensing of embryonic primordial germ cells for gametogenesis is dependent on signaling from the genital ridge.

Abstract
Imaging of nucleic acids is important for studying cellular processes such as cell division and apoptosis. A noninvasive label-free technique is attractive. Raman spectroscopy provides rich chemical information based on specific vibrational peaks. However, the signal from spontaneous Raman scattering is weak and long integration times are required, which drastically limits the imaging speed when used for microscopy. Coherent Raman scattering techniques, comprising coherent anti-Stokes Raman scattering (CARS) and stimulated Raman scattering (SRS) microscopy, overcome this problem by enhancing the signal level by up to five orders of magnitude. CARS microscopy suffers from a nonresonant background signal, which distorts Raman spectra and limits sensitivity. This makes CARS imaging of weak transitions in spectrally congested regions challenging. This is especially the case in the fingerprint region, where nucleic acids show characteristic peaks. The recently developed SRS microscopy is free from these limitations; excitation spectra are identical to those of spontaneous Raman and sensitivity is close to shot-noise limited. Herein we demonstrate the use of SRS imaging in the fingerprint region to map the distribution of nucleic acids in addition to proteins and lipids in single salivary gland cells of Drosophila larvae, and in single mammalian cells. This allows the imaging of DNA condensation associated with cell division and opens up possibilities of imaging such processes in vivo.

Abstract
The type IV secretion system (T4SS) of the plant intracellular symbiont Sinorhizobium meliloti 1021 is required for conjugal transfer of DNA. However, it is not required for host invasion and persistence, unlike the T4SSs of closely related mammalian intracellular pathogens. A comparison of the requirement for a bacterial T4SS in plant versus animal host invasion suggests an important difference in the intracellular niches occupied by these bacteria.

Abstract
Musicologists and linguists have often suggested that the prosody of a culture's spoken language can influence the structure of its instrumental music. However, empirical data supporting this idea have been lacking. This has been partly due to the difficulty of developing and applying comparable quantitative measures to melody and rhythm in speech and music. This study uses a recently-developed measure for the study of speech rhythm to compare rhythmic patterns in English and French language and classical music. We find that English and French musical themes are significantly different in this measure of rhythm, which also differentiates the rhythm of spoken English and French. Thus, there is an empirical basis for the claim that spoken prosody leaves an imprint on the music of a culture.
