The dual protein kinase-transcription factor, ERK5, is an emerging drug target in cancer and inflammation, and small-molecule ERK5 kinase inhibitors have been developed. However, selective ERK5 kinase inhibitors fail to recapitulate ERK5 genetic ablation phenotypes, suggesting kinase-independent functions for ERK5. Here we show that ERK5 kinase inhibitors cause paradoxical activation of ERK5 transcriptional activity mediated through its unique C-terminal transcriptional activation domain (TAD). Using the ERK5 kinase inhibitor, Compound 26 (ERK5-IN-1), as a paradigm, we have developed kinase-active, drug-resistant mutants of ERK5. With these mutants, we show that induction of ERK5 transcriptional activity requires direct binding of the inhibitor to the kinase domain. This in turn promotes conformational changes in the kinase domain that result in nuclear translocation of ERK5 and stimulation of gene transcription. This shows that both the ERK5 kinase and TAD must be considered when assessing the role of ERK5 and the effectiveness of anti-ERK5 therapeutics.Perception of pathogenic effectors in plants often relies on nucleotide-binding domain (NBS) and leucine-rich-repeat-containing (NLR) proteins. Some NLRs contain additional domains that function as integrated decoys for pathogen effector targets and activation of immune signalling. Wheat stripe rust is one of the most devastating diseases of crop plants. Here, we report the cloning of YrU1, a stripe rust resistance gene from the diploid wheat Triticum urartu, the progenitor of the A genome of hexaploid wheat. YrU1 encodes a coiled-coil-NBS-leucine-rich repeat protein with N-terminal ankyrin-repeat and C-terminal WRKY domains, representing a unique NLR structure in plants. Database searches identify similar architecture only in wheat relatives. Transient expression of YrU1 in Nicotiana benthamiana does not induce cell death in the absence of pathogens. The ankyrin-repeat and coiled-coil domains of YrU1 self-associate, suggesting that homodimerisation is critical for YrU1 function. The identification and cloning of this disease resistance gene sheds light on NLR protein function and may facilitate breeding to control the devastating wheat stripe rust disease.The growing sample size of genome-wide association studies has facilitated the discovery of gene-environment interactions (GxE). Here we propose a maximum likelihood method to estimate the contribution of GxE to continuous traits taking into account all interacting environmental variables, without the need to measure any. Extensive simulations demonstrate that our method provides unbiased interaction estimates and excellent coverage. We also offer strategies to distinguish specific GxE from general scale effects. Applying our method to 32 traits in the UK Biobank reveals that while the genetic risk score (GRS) of 376 variants explains 5.2% of body mass index (BMI) variance, GRSxE explains an additional 1.9%. Nevertheless, this interaction holds for any variable with identical correlation to BMI as the GRS, hence may not be GRS-specific. Still, we observe that the global contribution of specific GRSxE to complex traits is substantial for nine obesity-related measures (including leg impedance and trunk fat-free mass).An ideal solar-thermal absorber requires efficient selective absorption with a tunable bandwidth, excellent thermal conductivity and stability, and a simple structure for effective solar thermal energy conversion. Despite various solar absorbers having been demonstrated, these conditions are challenging to achieve simultaneously using conventional materials and structures. Here, we propose and demonstrate three-dimensional structured graphene metamaterial (SGM) that takes advantages of wavelength selectivity from metallic trench-like structures and broadband dispersionless nature and excellent thermal conductivity from the ultrathin graphene metamaterial film. The SGM absorbers exhibit superior solar selective and omnidirectional absorption, flexible tunability of wavelength selective absorption, excellent photothermal performance, and high thermal stability. Impressive solar-to-thermal conversion efficiency of 90.1% and solar-to-vapor efficiency of 96.2% have been achieved. These superior properties of the SGM absorber suggest it has a great potential for practical applications of solar thermal energy harvesting and manipulation.BACKGROUND Oxidative stress and myocardial apoptosis are features of doxorubicin-induced cardiac toxicity that can result in cardiac dysfunction. Previous studies showed that microRNA-143 (miR-143) was expressed in the myocardium and had a role in cardiac function. This study aimed to investigate the effects and possible molecular mechanisms of miR-143 on oxidative stress and myocardial cell apoptosis in a mouse model of doxorubicin-induced cardiac toxicity. MATERIAL AND METHODS Mice underwent intraperitoneal injection of doxorubicin (15 mg/kg) daily for eight days to develop the mouse model of doxorubicin-induced cardiac toxicity. Four days before doxorubicin administration, a group of mice was pretreated daily with a miR-143 antagonist (25 mg/kg/day) for four consecutive days by tail vein injection. The study included the use of a miR-143 antagomir, or anti-microRNA, an oligonucleotide that silenced endogenous microRNA (miR), and an agomir to miR-143, and also the AKT inhibitor, MK2206. Quantitative real-time polymerase chain reaction (qRT-PCR) and immunoblot analysis were used to measure mRNA and protein expression, respectively. RESULTS Doxorubicin treatment increased the expression of miR-143, which was reduced by the miR-143 antagomir. Overexpression of miR-143 increased doxorubicin-induced myocardial apoptosis and oxidative stress. The use of the miR-143 antagomir significantly activated protein kinase B (PKB) and AKT, which were reduced in the presence of the AKT inhibitor, MK2206. However, the use of the miR-143 antagomir further down-regulated AKT phosphorylation following doxorubicin treatment and increased AKT activation. CONCLUSIONS In a mouse model of doxorubicin-induced cardiac toxicity, miR-143 increased oxidative stress and myocardial cell apoptosis following doxorubicin treatment by inhibiting AKT.BACKGROUND CNS involvement in Hodgkin lymphoma is rare. Despite various treatment options, median overall survival is only 13 months after diagnosis of CNS involvement in relapsed/refractory HL. CASE REPORT A 29-year-old woman with classical HL (mixed cellularity) in clinical stage IIB was treated with multilineage chemotherapy and radiotherapy without achieving a sustained complete remission. Systemic and CNS progression of HL occurred at the age of 32 years and the patient received 2 cycles of brentuximab vedotin with bendamustine alternating with 2 cycles of high-dose methotrexate-based treatment and achieved partial remission. She then underwent autologous stem cell transplantation followed by brentuximab vedotin consolidation. The disease progressed and the patient died 6 months after the last dose of brentuximab vedotin. CONCLUSIONS We demonstrated a durable response to brentuximab vedotin-based chemotherapy in a patient with refractory Hodgkin lymphoma with CNS involvement. Prognosis of these patients is poor and new treatment options are needed.in English, Italian Il melanoma maligno può avere una localizzazione primitiva intestinale oppure essere la manifestazione secondaria di un melanoma extra intestinale. L’occlusione intestinale per intussuscezione da metastasi di melanoma è un evento molto raro e rappresenta in letteratura meno del 5% dei casi. I pazienti possono rimanere asintomatici e le metastasi possono manifestarsi anche 10 anni dopo la lesione primitiva. Infatti, meno del 5% delle metastasi di melanoma del tratto gastrointestinale vengono diagnosticate in vivo, solo a seguito dell’insorgenza di una complicanza come l’occlusione intestinale. In particolar modo il paziente si presenta con una sintomatologia del tutto aspecifica e pertanto la diagnosi viene posta a seguito dell’intervento chirurgico. Viene presentato il caso di una paziente donna di 58 anni con storia clinica di pregressa asportazione di un melanoma cutaneo 5 anni prima. La paziente viene ricoverata con diagnosi di addome acuto e sottoposta ad intervento chirurgico laparoscopico. Il quadro clinico di occlusione intestinale causata da intussuscezione secondaria a metastasi di melanoma cutaneo è una condizione molto rara e la chirurgia resettiva radicale è il trattamento curativo che consente la maggior sopravvivenza del paziente.in English, Italian SCOPO DELLO STUDIO La fibromatosi mesenterica primiva è un raro tipo di fibromatosi intra-addominale localmente invasiva, con un tasso di recidiva molto elevato. In questo studio, abbiamo mirato a presentare il nostro approccio chirurgico, le caratteristiche del tumore, la presentazione clinica e i risultati di follow-up a lungo termine nei casi di fibromatosi mesenterica primaria. MATERIALE E METODI I dati raccolti da 11 pazienti sottoposti a intervento chirurgico a causa della fibromatosi mesenterica primaria nella nostra clinica tra il 2010 e il 2019 sono stati analizzati retrospettivamente. RISULTATI Il nostro studio è fondato su 11 pazienti sei donne e 5 uomini, di età media di 44,2±15,8 anni. La massa addominale è stata rilevata in 5 pazienti (45,5%) che avevano lamentato ostruzione meccanica dell’intestino con nausea e vomito, dolore addominale, distensione addominale. Due pazienti (18,2%) sono stati operati con una diagnosi di addome acuto in situazioni di emergenza per ostruzione la pianificazione del trattamento chirurgico.

Physical activity (PA) may be influential for prolonging health and functioning, warranting characterization of its patterns over the life course in population-based data. With the availability of up to three self-reported assessments of past year leisure-time PA (LTPA) over multiple decades in 15,036 participants (26% African American; 55% women; mean baseline age=54; median follow-up=23 years) from the Atherosclerosis Risk in Communities (ARIC) Study sampled from four U.S. communities, race-sex-stratified trajectories of average weekly intensity (metabolic equivalent of task (MET)), duration (hours), and energy expenditure or volume (MET-h) of LTPA were developed from age 45 to 90 using joint models to accommodate expected non-ignorable attrition. Declines in weekly LTPA intensity, duration, and volume from age 70 to 90 were observed in white women (2.9 to 1.2 MET; 2.5 to 0.6 h; 11.1 to 2.6 MET-h), white men (2.5 to 1.0 MET; 3.5 to 1.8 h; 15.5 to 6.4 MET-h), African American women (2.5 to 2.4 MET; 0.8 to 0.1 h; 6.7 to 6.0 MET-h), and African American men (2.3 to 1.4 MET; 1.5 to 0.6 h; 8.0 to 2.3 MET-h). These data reveal population-wide shifts towards less active lifestyles in older adulthood.Development of specific serum biomarkers is essential to improve diagnosis and prognosis of non-small cell lung cancer (NSCLC). Here, we show that serum and tissue levels of miR-519d are significantly decreased in NSCLC patients. The low expression of miR-519d is associated with lymph node metastases, clinical stage, and a poor prognosis in NSCLC patients. In addition, ROC analysis demonstrated that the serum miR-519d levels can distinguish NSCLC patients from healthy controls. MiR-519d inhibits proliferation, migration, and invasion by lung cancer cells, indicating that it may function as a tumor suppressor in lung cancer. Furthermore, our data demonstrate that HER3 is a target gene of miR-519d in lung cancer cells, and show that by targeting HER3, miR-519d inhibits the PI3K/Akt pathway. These findings demonstrate that the miR-519d levels are decreased in serum and tumor tissues of NSCLC patients, and indicate that miR-519d regulates NSCLC progression by targeting HER3. MiR-519d could potentially serve as a novel serum biomarker for NSCLC.
