Polycystic ovary syndrome (PCOS) is a complex reproductive disorder often associated with obesity, insulin resistance, and dyslipidemia. Hormonal changes in PCOS may also include altered glucocorticoid signaling. Our aim was to examine whether alterations in hepatic glucocorticoid signaling are associated with disturbances of glucose and lipid metabolism in animal model of PCOS.

Female rats, 3 weeks old, were subcutaneously implanted with 5α-dihydrotestosterone (DHT) or placebo pellets for 90 days to induce PCOS. Expression of 11β-hydroxysteroid dehydrogenase 1 (11βHSD1) and A-ring reductases (5α and 5β), as well as intracellular distribution of glucocorticoid receptor (GR) and expression of its regulated genes were examined in the liver. Proteins of hepatic lipid and carbohydrate metabolism and markers of inflammation were also assessed.

DHT treatment induced increase in body and liver mass, as well as in triglycerides and free fatty acids levels in plasma. Elevation of 11βHSD1 and reduction of 5α-redutriglyceride synthesis and hypertriglyceridemia.Hormone-dependent breast cancer is the most abundant molecular subtype of the disease. Despite the availability of endocrine treatments, the use of these drugs is limited by their serious adverse reactions and development of acquired resistance often mediated by growth factor receptors. The hepatocyte growth factor receptor, MET, is a receptor tyrosine kinase known for its oncogenic activity and mediating resistance to targeted therapies. Crizotinib is a small-molecule tyrosine kinase inhibitor of MET. In this study, the anticancer effects of combined crizotinib and endocrine drugs were investigated in breast cancer cells in vitro along with the molecular mechanisms associated with these effects. Results showed that crizotinib inhibited growth of MCF7 and T-47D breast cancer cells in a dose-dependent manner with IC50 values of 2.88 μM and 0.93 μM, respectively. Combined treatment of crizotinib and 4-hydroxytamoxifen resulted in synergistic growth inhibition of MCF7 and T-47D cells with combination index values of 0.39 and 0.8, respectively. The combined treatment significantly suppressed migration and colony formation of MCF7 and T-47D cells. see more Immunofluorescence showed a significant reduction of the expression of the nuclear protein Ki-67 with the combination of crizotinib and 4-hydroxytamoxifen in both cell lines. Western blotting indicated that the combination treatment reduced the levels of active and total MET, estrogen receptor α (ERα), total and active levels of AKT, ERK, c-SRC, NFĸB p65, GSK-3β, and the anti-apoptotic BCL-2 protein. Findings from this study suggest a potential role of MET inhibitors in breast cancer treatment as monotherapy or combination with endocrine drugs.
High-dimensional flow cytometry experiments have become a method of choice for high-throughput integration and characterization of cell populations. Here, we present a summary of state-of-the-art R-based pipelines used for differential analyses of cytometry data, largely based on chimeric antigen receptor (CAR) T cell therapies. These pipelines are based on publicly available R libraries, put together in a systematic and functional fashion, therefore free of cost.

In recent years, existing tools tailored to analyze complex high-dimensional data such as single-cell RNA sequencing (scRNAseq) have been successfully ported to cytometry studies due to the similar nature of flow cytometry and scRNAseq platforms. Existing environments like Cytobank (Kotecha et al., 2010), FlowJo (FlowJo™ Software) and FCS Express (https//denovosoftware.com) already offer a variety of these ported tools, but they either come at a premium or are fairly complicated to manage by an inexperienced user. To mitigate these limitations, airly complicated to manage by an inexperienced user. To mitigate these limitations, experienced cytometrists and bioinformaticians usually incorporate these functions into an RShiny (https//shiny.rstudio.com) application that ultimately offers a user-friendly, intuitive environment that can be used to analyze flow cytometry data. Computational tools and Shiny-based tools are the perfect answer to the ever-growing dimensionality and complexity of flow cytometry data, by offering a dynamic, yet user-friendly exploratory space, tailored to bridge the space between the lab experimental world and the computational, machine learning space.The current, global situation regarding the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic and its potentially devastating clinical manifestations, i.e. coronavirus disease 2019 (COVID-19), took the world by storm, as millions of people have been infected worldwide and more than 1,600,000 patients have succumbed. Infection induced by various respiratory viruses may lead to thrombotic complications. Infection-elicited thrombosis may involve a repertoire of distinct, yet interconnected pathophysiological mechanisms, implicating a hyperinflammatory response, platelet activation and triggering of the coagulation cascade. In the present review, we present current knowledge on the pathophysiological mechanisms that may underlie thrombotic complications in SARS-CoV-2 infection. Furthermore, we provide clinical data regarding the incidence rate of thrombotic events in several viral respiratory infections that cause acute respiratory distress syndrome, including SARS-CoV-2 infection and finally we summarize current recommendations concerning thromboprophylaxis and antithrombotic therapy in patients with thrombotic complications related to SARS-CoV-2 infection.Chronic, systemic inflammation is implicated in physical and mental health; little is known about whether sex and racial differences detected in adulthood are observed during adolescence or about normative changes occurring during adolescence. This longitudinal, United States-based study examined four biomarkers of systemic inflammation [C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and IL-8) in 315 adolescents (51% female; 58% black; baseline age = 16.49 years (SD = 1.56; range 12.14-21.28)] at three timepoints. Notable results included general decline in inflammatory biomarkers in older adolescents, lower levels of TNF-α/IL-8 in black adolescents, elevated CRP/IL-6 in females, and especially higher levels of IL-6 in black, female adolescents. Implications are discussed, particularly the potential health implications of elevated IL-6 in black females.
