The hypothesis we tested was that administering corticotropin-releasing factor receptor agonists preserves muscle mass during cancer that is related to changes in tissue gene expression. cDNA microarrays were used to compare mRNAs from muscle and adipose tissues of non-treated and agonist-treated tumor-bearing rats. In muscle of non-tumor-bearing agonist-treated animals we observed decreased expre

In fast- and slow-twitch limb and heart muscles of cachectic rats, redox balance and muscle structure were explored. The nature of the oxidatively modified proteins also was identified in these muscles. Reactive carbonyls, hydroxynonenal (HNE)- and malondialdehyde (MDA)-protein adducts, and antioxidant enzyme levels were determined in limb and heart muscles of cachectic (7 days after inoculation o

I boken "En lundensisk litteraturhistoria. Lunds universitet som litterärt kraftfält" presenteras cirka 200 författare från 1600-talet till i dag. Haquin Spegel, Bengt Lidner, Clas Livijn, Esaias Tegnér, Hjalmar Gullberg, Majken Johansson, Göran Sonnevi, Sigrid Combüchen, Lina Wolff – alla har de anknytning till Lunds universitet. Författarpresentationerna kompletteras med tematiska tvärsnitt om ä

Cancer patients commonly suffer from cachexia, a syndrome in which tumors induce metabolic changes in the host that lead to massive loss in skeletal muscle mass. Using a preclinical mouse model of cancer cachexia, we tested the hypothesis that tumor inoculation causes a reduction in ATP synthesis and genome-wide aberrant expression in skeletal muscle. Mice implanted with Lewis lung carcinomas were

BACKGROUND & AIMS: The abnormalities associated with cancer cachexia include anorexia, weight loss, muscle loss and atrophy, anaemia and alterations in carbohydrate, lipid and protein metabolism. The aim of the present investigation was to examine the anti-wasting effects of some nutraceuticals such as genistein, resveratrol, epigallocatechin gallate and diallyl sulphide (DAS).METHODS: The in

C2C12 cells exposed to hyperthermia (41 degrees C) experienced an increase in both protein synthesis and degradation. The addition of IL15 under hyperthermic conditions resulted in an important increase in protein synthesis with no changes in protein degradation, except when cells overexpressed PPARdelta. The PPARdelta agonist GW501516 exerted similar effects on protein synthesis to IL15. Expressi

Previous studies have demonstrated an effect of corticotropin-releasing factor 2 receptor (CRF2R) agonists in the maintenance of skeletal muscle mass. The aim of this study was to evaluate the effects of a CRF2R agonist in preserving skeletal muscle in a mouse cachexia model. Implantation of a fast-growing tumor to mice (Lewis lung carcinoma) resulted in a clear cachectic state characterized by a

Implantation of the Yoshida AH-130 ascites hepatoma to rats resulted in a decrease in muscle weight 7 days after the inoculation of the tumor. These changes were associated with increases in the mRNA content for both peroxisome proliferator-activated receptor (PPAR) gamma and PPAR delta in skeletal muscle. The increase in gene expression for these transcription factors was related to increases in

Proteolysis in skeletal muscle is mainly carried out by the activity of the ubiquitin-dependent proteolytic system. For the study of protein degradation through the ubiquitin-proteasome pathway, we used a model of hyperthermia in murine myotubes. In C2C12 cells, hyperthermia (41°C) induced a significant increase in both the rate of protein synthesis (18%) and degradation (51%). Interestingly, the

In our homes we enjoy daylight reaching the rooms through the windows, and artificial lighting when there is not enough daylight available. Electrical lighting has been used in Western homes since the late 1910s. We have experienced the technical development from warm incandescent light bulbs to energy-efficient light emitting diods (LED). In Sweden we lack daylight in winter and have a lot of day

Despite promises that they can contribute toward more environmentally beneficial transportation there are many sustainability concerns about liquid transport biofuels. In response to pressure from civil society, the European Union (EU) has introduced sustainability criteria for biofuels. A hybrid regulatory system involving state and non-state actors stipulates that retailers and producers must co

The book “Energy and Transport in Green Transitions – Perspectives on Ecomodernity” deals with the societally and scientifically crucial topic of energy and climate change mitigation. The book starts by setting high ambitions as the authors attempt “to go beyond both the extremism of the anti-capitalist critique and the radical enthusiasm of techno-economic positivism” in their exploration to find

The report examines the integrated Nordic power market and its linkages to renewable energy technology (RET) deployment for power production. It has two purposes. First, it aims to improve the understanding of the expansion of the Nordic power market and integration and deployment of RET. Secondly, it takes lessons from the Nordic experience that could inform the development, deployment and integr
