PURPOSE: Leisure-screen-time, including TV viewing, is associated with increased mortality risk. We estimated the all-cause mortality risk reductions associated with substituting leisure-screen-time with different discretionary physical activity types, and the change in mortality incidence associated with different substitution scenarios. METHODS: 423,659 UK Biobank participants, without stroke, myocardial infarction or cancer history, were followed for 7.6 (1.4) (median (IQR)) years...

Physical activity (PA) levels are low in patients with lung cancer. Emerging evidence supports the use of interventions to increase PA in this population. We aimed to (1) identify and synthesize outcome measures which assess PA levels in patients with lung cancer and (2) to evaluate, synthesize and compare the psychometric properties of these measures. A systematic review of articles from searches was conducted of five electronic databases and personal records. Eligible studies were those which assessed PA using either performance-based or patient-reported measures...

Mechanistic target of rapamycin complex 1 (MTORC1) and PLK1 (polo like kinase 1) are major drivers of cancer cell growth and proliferation, and inhibitors of both protein kinases are currently being investigated in clinical studies. To date, MTORC1's and PLK1's functions are mostly studied separately, and reports on their mutual crosstalk are scarce. Here, we identify PLK1 as a physical MTORC1 interactor in human cancer cells. PLK1 inhibition enhances MTORC1 activity under nutrient sufficiency and in starved cells, and PLK1 directly phosphorylates the MTORC1 component RPTOR/RAPTOR in vitro...

Collective cell migration in spreading epithelia in controlled environments has become a landmark in our current understanding of fundamental biophysical processes in development, regeneration, wound healing or cancer. Epithelial monolayers are treated as thin layers of a viscous fluid that exert active traction forces on the substrate. The model is exactly solvable and shows a broad range of applicabilities for the quantitative analysis and interpretation of force microscopy data of monolayers from a variety of experiments and cell lines...

To further inform implementation efforts of a telephone-based physical activity (PA) intervention for breast cancer survivors, we assessed the PA, fatigue, mood, and quality of life of the peer mentors/coaches who delivered the program. The coaches were volunteers with the American Cancer Society's Reach to Recovery program. The coaches (n = 18) delivered the PA intervention to 76 breast cancer survivors in a randomized controlled trial. Coaches completed assessments of PA (self-report), motivational readiness for PA, and standardized measures of psychosocial variables at the start of coaching and at study exit...

INTRODUCTION: Cancer is a growing health, social and economic problem. 1 in 3 people in the UK will develop cancer in their lifetime. With survival rates rising to over 50%, the long-term needs of cancer survivors are of growing importance. Cancer rehabilitation is tailored to address the physical or psychosocial decline in ability to engage in daily activities. Its use is supported by high-quality international, multicentre research. Incorporating strategies for self-management behaviour development into rehabilitation can prepare individuals for cancer survivorship...

BACKGROUND: While the increasing number of people surviving cancer is promising, the long-term health effects warrant broad, innovative interventions. We investigated the feasibility and acceptability of a 24-week intervention called 'Active Book Club' comprising audio book listening, pedometer walking and supervised book club meetings. MATERIAL AND METHODS: An exploratory and descriptive design was applied. Qualitative data included baseline and post-intervention focus group interviews as well as post-intervention individual interviews...

Physical activity (PA) and vitamin D are thought to affect colorectal cancer prognosis. The present study investigates associations between 25(OH)D3 and PA in prospectively followed colorectal cancer patients in the ColoCare study. At 6, 12, and 24 mo after surgery, patients donated a blood sample, wore an accelerometer for 10 consecutive days, and completed a PA questionnaire. Plasma 25-hydroxyvitamin D3 (25(OH)D3) levels were measured by high-performance liquid chromatography. We tested associations using partial correlations and multivariate linear regression analysis, adjusted for season, age, and body mass index...

The activation and overexpression of fibroblast growth factor receptors (FGFRs) are highly correlated with a variety of cancers. Most small molecule inhibitors of FGFRs selectively target FGFR1-3, but not FGFR4. Hence, designing highly selective inhibitors towards FGFR4 remains a great challenge because FGFR4 and FGFR1 have a high sequence identity. Recently, two small molecule inhibitors of FGFRs, ponatinib and AZD4547, have attracted huge attention. Ponatinib, a type II inhibitor, has high affinity towards FGFR1/4 isoforms, but AZD4547, a type I inhibitor of FGFR1, displays much reduced inhibition toward FGFR4...

Metronomic chemotherapy has translated into favorable toxicity profile and capable of delaying tumor progression. Despite its promise, conventional injectable chemotherapeutics are not meaningful to use as metronomic for personalized therapy in long-term cancer treatments due to its frequent administration. This study aims to exploit the benefits of the oral application of carboplatin as metronomic therapy for non-small cell lung cancer (NSCLC). We developed an orally active carboplatin by physical complexation with a deoxycholic acid (DOCA)...

BACKGROUND: Most cancer survivors are able to return to work at some point after diagnosis. However, literature on sustained employability and health-related quality of life (HRQoL) is limited. Therefore, the aims of this study were to explore the influence of change in employment status on HRQoL in cancer survivors long term after diagnosis, and to identify predictors of work continuation in occupationally active survivors. MATERIAL AND METHODS: We used prospective data (T0 = two years after diagnosis, T1 = one-year follow-up, and T2 = two-year follow-up) from a cohort of cancer survivors that had an employment contract and were of working age at T0 (N = 252, 69...

Muscle weakness and atrophy are key characteristics of the aging adult but can also be found in chronically ill patients with heart failure, cancer, renal failure, and chronic infectious diseases all associated with an accelerated level of muscle dysfunction. Reduced physical activity levels and exercise intolerance increase muscle loss and decrease quality of life in both the aging and heart failure populations. The purpose of this review is to provide an overview of the effects of aging and heart failure on skeletal muscle function and how exercise training can improve long-term outcomes associated with skeletal muscle dysfunction...

NF-κB and STAT3 are essential transcription factors in immunity and act at the interface of the transition from chronic inflammation to cancer. Different functional crosstalks between NF-κB and STAT3 have been recently described arguing for a direct interaction of both proteins. During a systematic analysis of NF-κB/STAT3 crosstalk we observed that appearance of the subcellular distribution of NF-κB and STAT3 in immunofluorescence heavily depends on the fixation procedure. Therefore, we established an optimized fixation protocol for the reliable simultaneous analysis of the subcellular distributions of both transcription factors...

Microparticles have been shown to shed from a variety of viable cells as a consequence of inflammatory processes, activation or physical stress. Seventy to 90% of circulating microparticles are thought to be platelet-derived. The content of microparticles in blood collected from normal blood donors is highly variable and transfers into the final blood component. Elevated microparticle content (MPC) in donor blood might indicate an asymptomatic clinical condition of the donor which might affect the transfusion recipient, particularly pediatric patients...
