Lymphatic endothelium stimulates melanoma metastasis and invasion via MMP14-dependent Notch3 and b1-integrin activation

Lymphatic invasion and lymph node metastasis correlate with poor clinical outcome in melanoma. However, the mechanisms of lymphatic dissemination in distant metastasis remain incompletely understood. We show here that exposure of expansively growing human WM852 melanoma cells, but not singly invasive Bowes cells, to lymphatic endothelial cells (LEC) in 3D co-culture facilitates melanoma distant organ metastasis in mice. To dissect the underlying molecular mechanisms, we established LEC co-cultures with different melanoma cells originating from primary tumors or metastases. Notably, the expansively growing metastatic melanoma cells adopted an invasively sprouting phenotype in 3D matrix that was dependent on MMP14, Notch3 and β1-integrin. Unexpectedly, MMP14 was necessary for LEC-induced Notch3 induction and coincident β1-integrin activation. Moreover, MMP14 and Notch3 were required for LEC-mediated metastasis of zebrafish xenografts. This study uncovers a unique mechanism whereby LEC contact promotes melanoma metastasis by inducing a reversible switch from 3D growth to invasively sprouting cell phenotype

StopCOVID cohort : An observational study of 3,480 patients admitted to the Sechenov University hospital network in Moscow city for suspected COVID-19 infection

© 2020 Oxford University Press. This is a pre-copyedited, author-produced PDF of an article accepted for publication in Clinical Infectious Diseases following peer review. The version of record is available online at: https://doi.org/10.1093/cid/ciaa1535.BACKGROUND: The epidemiology, clinical course, and outcomes of COVID-19 patients in the Russian population are unknown. Information on the differences between laboratory-confirmed and clinically-diagnosed COVID-19 in real-life settings is lacking. METHODS: We extracted data from the medical records of adult patients who were consecutively admitted for suspected COVID-19 infection in Moscow, between April 8 and May 28, 2020. RESULTS: Of the 4261 patients hospitalised for suspected COVID-19, outcomes were available for 3480 patients (median age 56 years (interquartile range 45-66). The commonest comorbidities were hypertension, obesity, chronic cardiac disease and diabetes. Half of the patients (n=1728) had a positive RT-PCR while 1748 were negative on RT-PCR but had clinical symptoms and characteristic CT signs suggestive of COVID-19 infection.No significant differences in frequency of symptoms, laboratory test results and risk factors for in-hospital mortality were found between those exclusively clinically diagnosed or with positive SARS-CoV-2 RT-PCR.In a multivariable logistic regression model the following were associated with in-hospital mortality; older age (per 1 year increase) odds ratio [OR] 1.05 (95% confidence interval (CI) 1.03 - 1.06); male sex (OR 1.71, 1.24 - 2.37); chronic kidney disease (OR 2.99, 1.89 - 4.64); diabetes (OR 2.1, 1.46 - 2.99); chronic cardiac disease (OR 1.78, 1.24 - 2.57) and dementia (OR 2.73, 1.34 - 5.47). CONCLUSIONS: Age, male sex, and chronic comorbidities were risk factors for in-hospital mortality. The combination of clinical features were sufficient to diagnoseCOVID-19 infection indicating that laboratory testing is not critical in real-life clinical practice.Peer reviewe

Characterising long COVID: a living systematic review

BACKGROUND: While it is now apparent clinical sequelae (long COVID) may persist after acute COVID-19, their nature, frequency and aetiology are poorly characterised. This study aims to regularly synthesise evidence on long COVID characteristics, to help inform clinical management, rehabilitation strategies and interventional studies to improve long-term outcomes. METHODS: A living systematic review. Medline, CINAHL (EBSCO), Global Health (Ovid), WHO Global Research on COVID-19 database, LitCovid and Google Scholar were searched till 17 March 2021. Studies including at least 100 people with confirmed or clinically suspected COVID-19 at 12 weeks or more post onset were included. Risk of bias was assessed using the tool produced by Hoy et al. Results were analysed using descriptive statistics and meta-analyses to estimate prevalence. RESULTS: A total of 39 studies were included: 32 cohort, 6 cross-sectional and 1 case-control. Most showed high or moderate risk of bias. None were set in low-income countries and few included children. Studies reported on 10 951 people (48% female) in 12 countries. Most included previously hospitalised people (78%, 8520/10 951). The longest mean follow-up time was 221.7 (SD: 10.9) days post COVID-19 onset. Over 60 physical and psychological signs and symptoms with wide prevalence were reported, most commonly weakness (41%; 95% CI 25% to 59%), general malaise (33%; 95% CI 15% to 57%), fatigue (31%; 95% CI 24% to 39%), concentration impairment (26%; 95% CI 21% to 32%) and breathlessness (25%; 95% CI 18% to 34%). 37% (95% CI 18% to 60%) of patients reported reduced quality of life; 26% (10/39) of studies presented evidence of reduced pulmonary function. CONCLUSION: Long COVID is a complex condition with prolonged heterogeneous symptoms. The nature of studies precludes a precise case definition or risk evaluation. There is an urgent need for prospective, robust, standardised, controlled studies into aetiology, risk factors and biomarkers to characterise long COVID in different at-risk populations and settings.

Современные подходы к выявлению и изучению эпигенетически активных ксенобиотиков

Objective. Review of the modern methodological approaches for testing and studying the epigenetic activity of xenobiotics.Materials and methods. In preparing the review, we used information databases of biomedical literature SciVerse Scopus (538), PubMed (746), Web of Science (625), RSCI (45). To obtain full-text documents, electronic resources of PubMed Central (PMC), Research Gate, RSCI, CyberLeninka were used. In the text of the review, 87 modern publications (2010–2019) were cited, as well as 17 earlier articles published by the founders of the methods, which are used today.Results. In the review, current data on epigenetic regulation for gene expression at the level of DNA methylation and histone modification are discussed, in vitro model systems and model organisms are described, and modern methods for screening of epigenetically active xenobiotics are presented.Conclusion. Modern data concerning the mechanisms of epigenetic regulation of gene expression, the usage of existing model systems and model organisms, as well as the application of various methodological approaches and techniques, allow extensive screening of xenobiotics (including drugs and compounds synthesized for national economic tasks) for epigenetic activity. The identification of epigenetically active compounds is important in terms of improving the prevention and treatment of a number of diseases and, in particular, malignant neoplasms.Цель исследования – анализ существующих методических подходов к тестированию и изучению эпигенетической активности ксенобиотиков.Материалы и методы. При подготовке обзора были использованы информационные базы биомедицинской литературы SciVerse Scopus (538), PubMed (746), Web of Science (625), РИНЦ (45). Для получения полнотекстовых документов использованы электронные ресурсы PubMed Central (PMC), Research Gate, РИНЦ, КиберЛенинка. В тексте обзора процитированы 87 современных публикаций (2010–2019 гг.), а также 17 статей основоположников анализируемых в обзоре методик, которые используются и в наши дни.Результаты. В обзоре рассмотрены современные данные по основным закономерностям функционирования системы регуляции экспрессии генов на уровне метилирования ДНК и модификации гистонов, описаны модельные организмы, используемые как при тестировании ксенобиотиков на эпигенетическую активность, так и для детального изучения их конкретных эффектов на отдельные механизмы эпигенетической регуляции транскрипции. Поскольку в настоящее время не разработаны тест-системы, позволяющие интегрально оценить эффекты ксенобиотиков на эпигенетическую систему регуляции транскрипции, в обзоре представлены методы оценки выявления влияний различных факторов окружающей среды, в том числе различных ксенобиотиков, на метилирование ДНК и модификацию гистонов.Заключение. Современные представления о механизмах эпигенетической регуляции экспрессии генов, использование существующих модельных систем и модельных организмов, а также применение различных методологических и методических подходов позволяют проводить широкое тестирование ксенобиотиков, в том числе медицинских препаратов и соединений, синтезированных для выполнения народнохозяйственных задач, на эпигенетическую активность. Выявление эпигенетически активных соединений важно в плане совершенствования профилактики и лечения ряда заболеваний и, прежде всего, злокачественных новообразований
