BACKGROUND: Combinations of exercise and nutritional interventions might improve the functional prognosis for cachectic cancer patients. However, high attrition and poor compliance with interventions limit their efficacy. We aimed to test the feasibility of the early induction of new multimodal interventions specific for elderly patients with advanced cancer Nutrition and Exercise Treatment for Advanced Cancer (NEXTAC) programme. METHODS: This was a multicentre prospective single-arm study...

BACKGROUND: Recreational physical activity has been consistently associated with reduced breast cancer risk. Less is known about how family history of breast cancer impacts the association, and whether it varies by menopausal status. METHODS: The Sister Study is a cohort of 50,884 women who had a sister with breast cancer, but no prior breast cancer themselves. Women reported all recreational sport/exercise activities they participated in over the past 12 months...

BACKGROUND: Physical activity is associated with a lower risk of disease recurrence among colon cancer patients. Circulating tumor cells (CTC) are prognostic of disease recurrence among stage I-III colon cancer patients. The pathways through which physical activity may alter disease outcomes are unknown, but may be mediated by changes in CTCs. METHODS: Participants included 23 stage I-III colon cancer patients randomized into one of three groups: usual-care control, 150 min∙wk-1 of aerobic exercise (low-dose), and 300 min∙wk-1 of aerobic exercise (high-dose) for six months...

Insulin-resistance (IR)-related genetic variants are possibly associated with breast cancer, and the gene-phenotype-cancer association could be modified by lifestyle factors including obesity, physical inactivity, and high-fat diet. Using data from postmenopausal women, a population highly susceptible to obesity, IR, and increased risk of breast cancer, we implemented a genome-wide association study (GWAS) in 2 steps: 1) GWAS meta-analysis of gene-environmental (i.e., behavioral) interaction (G*E) for IR phenotypes (hyperglycemia, hyperinsulinemia, and homeostatic model assessment-insulin resistance); and 2) after the G*E GWAS meta-analysis, the identified single-nucleotide polymorphisms (SNPs) were tested for their associations with breast cancer risk in overall or subgroup population, where the SNPs were identified at genome-wide significance...

The activation or polarization of macrophages to pro- or anti-inflammatory states evolved as an adaptation to protect against a spectrum of biological threats. Such an adaptation engages pro-oxidative mechanisms and enables macrophages to neutralize and kill threatening organisms (e.g., viruses, bacteria, mold), limit cancerous growths, and enhance recovery and repair processes. The present study demonstrates that (1) many diverse pharmacological, chemical and physical agents can mediate a dose/concentration-dependent shift between pro- and anti-inflammatory activation states, and (2) these shifts in activation states display biphasic dose-response relationships that are characteristic of hormesis...

Prostate cancer (PCa) is the most common type of cancer in men with high morbidity and mortality. However, the current treatment with drugs often leads to chemotherapy resistance. It is known that the multi-disciplines research on molecular imaging is very helpful for early diagnosing, staging, restaging and precise treatment of PCa. In the past decades, the tumor-specific targeted drugs were developed for the clinic to treat prostate cancer. Among them, the emerging nanotechnology has brought about many exciting novel diagnosis and treatments systems for PCa...

MAX giant associated protein (MGA) is a dual transcriptional factor containing both T-box and bHLHzip DNA binding domains. In vitro studies have shown that MGA functions as a transcriptional repressor or activator to regulate transcription of promotors containing either E-box or T-box binding sites. BS69 (ZMYND11), a multidomain-containing (i.e., PHD, BROMO, PWWP, and MYND) protein, has been shown to selectively recognizes histone variant H3.3 lysine 36 trimethylation (H3.3K36me3), modulates RNA Polymerase II elongation, and functions as RNA splicing regulator...

Within populations carrying the same genetic predisposition, the penetrance of BRCA1 mutations has increased over time. Although linked to changes in lifestyle factors associated with energy metabolism, these observations cannot be explained by the established role of BRCA1 in DNA repair alone. We manipulated BRCA1 expression using tetracycline in the UBR60-bcl2 cell line (which has an inducible, tetracycline-regulated BRCA1 expression) and siRNA in oestrogen receptor(ER)-positive MCF7 and T47D breast cancer cells...

Introduction: Several studies have provided important information about health conditions and other challenges faced by women diagnosed with breast cancer and how they can improve their quality of life and reduce their risk of cancer recurrence. Although African American and Hispanic breast cancer patients have a poorer survival than their white counterparts, few studies have compared the experiences of African American, Hispanic, and non-Hispanic white breast cancer survivors. Objectives: To facilitate collaborative studies on breast cancer survivorship in a multicultural population, including future intervention research on nutrition, and physical activity, and clinical substudies...
