Cancer-induced cachexia, characterized by muscle wasting, is a lethal metabolic syndrome with undefined etiology. Current consensus is that multiple factors contribute to cancer-induced muscle wasting, and therefore therapy requires combinational strategies. Here, we show that Toll-like receptor 4 (TLR4) mediates cancer-induced muscle wasting by directly activating muscle catabolism as well as stimulating an innate immune response in mice bearing Lewis lung carcinoma (LLC), and targeting TLR4 alone effectively abrogate muscle wasting...

Cancer cachexia is a severe and disabling clinical condition that frequently accompanies the development of many types of cancer. Muscle wasting is the hallmark of cancer cachexia and is associated with serious clinical consequences such as physical impairment, poor quality of life, reduced tolerance to treatments and shorter survival. Cancer cachexia may evolve through different stages of clinical relevance, namely pre-cachexia, cachexia and refractory cachexia. Given its detrimental clinical consequences, it appears mandatory to prevent and/or delay the progression of cancer cachexia to its refractory stage by implementing the early recognition and treatment of the nutritional and metabolic alterations occurring during cancer...

Cancer cachexia is a progressive wasting syndrome characterized by anorexia and weight loss, specifically muscle wasting and fat depletion. There is no therapeutic agent for treatment of this syndrome. We investigated the anti-cachexia effects of Z-505 hydrochloride (Z-505), a new oral growth hormone secretagogue receptor 1a (GHSR1a) agonist, using a mouse model of cancer cachexia. We performed a calcium flux assay in Chinese hamster ovary (CHO-K1) cells stably expressing human GHSR1a to quantify the agonistic activity of Z-505...

A key feature of cancer cachexia is the loss of adipose tissue, mainly due to increased lipolysis and an impairment of adipogenesis. Recent findings have shown that cancer exosomes promoted lipolysis in adipose tissue. However, effects of cancer exosomes on adipogenesis were not reported. In this study, we found that lung cancer exosomes could be internalized by human adipose tissue-derived mesenchymal stem cells (hAD-MSCs) and significantly inhibited hAD-MSC adipogenesis as demonstrated by Oil Red O staining and decreased expression of adipogenic-specific genes...

The majority of cancer patients with advanced disease experience weight loss, including loss of lean body mass. Severe weight loss is characteristic for cancer cachexia, a condition that significantly impairs functional status and survival. The underlying causes of cachexia are incompletely understood, and currently no therapeutic approach can completely reverse the condition. Autophagy coordinates lysosomal destruction of cytosolic constituents and is systemically induced by starvation. We hypothesized that starvation-mimicking signaling compounds secreted from tumor cells may cause a systemic acceleration of autophagy during cachexia...

Cancer cachexia is characterised by involuntary weight loss associated with systemic inflammation and metabolic changes. Studies aimed at maintaining lean body mass in cachectic tumour-bearing hosts have made important contributions reducing the number of deaths and improving the quality of life. In recent years, leucine has demonstrated effective action in maintaining lean body mass by decreasing muscle protein degradation. Currently, there is a growing need to understand how leucine stimulates protein synthesis and acts protectively in a cachectic organism...

OBJECTIVE: Cancer cachexia is often present in patients with advanced malignant tumors, and the subsequent body weight reduction results in poor quality of life. However, there has been no progress in developing effective clinical therapeutic strategies for skeletal muscle wasting in cancer cachexia. Herein, we explored the functions of pantoprazole on cancer cachexia skeletal muscle wasting. METHODS: The mouse colon adenocarcinoma cell line C26 was inoculated in the right forelimb of male BALB/C mice to establish a cancer cachexia model...

Many leukemia patients suffer from dysregulation of their immune system, making them more susceptible to infections and leading to general weakening (cachexia). Both adaptive and innate immunity are affected. The fruitfly Drosophila melanogaster has an innate immune system including cells of the myeloid lineage (hemocytes). To study Drosophila immunity and physiology during leukemia we established three models by driving expression of a dominant-active version of the Ras oncogene (Ras(V12) ) alone or combined with knockdowns of tumor suppressors in Drosophila hemocytes...

Cachexia is defined as a complex metabolic syndrome associated with underlying illness that is characterized by the loss of body weight consisting of muscle and fat mass wasting. Sarcopenia is defined as the ageing related loss of muscle mass in health and disease that may not have an effect on body weight. As millions of patients are in cachectic or sarcopenic states, both conditions contribute to high numbers to death worldwide. A number of treatments have been proposed for cachexia and sarcopenia, but these are either in the preclinical stage or in clinical trials and hence not available to the general population...

The gastrointestinal hormone ghrelin reduces energy expenditure and stimulates food intake. Ghrelin analogs are a possible treatment against cancer anorexia-cachexia syndrome (CACS). This study aimed to investigate whether oral treatment with the non-peptidergic ghrelin receptor agonist HM01 counteracts CACS in colon-26 (C26) tumor-bearing mice. The C26 tumor model is characterized by pronounced body weight (BW) loss and muscle wasting in the absence of severe anorexia. We analyzed the time course of BW loss, body composition, muscle mass, bone mineral density, and the cytokines interleukin-6 (IL-6) and macrophage-inhibitory cytokine-1 (MIC-1)...

Sporadic pancreatic cancer amounts to ∼90% of all pancreatic cancers. It is a gloomy, depressive disease: the formula describes well the behavior of many SPC patients, and the most recalcitrant malignancy, with a very low 5-year survival (3-6%). At present, diagnostic methods are commonly applied, as used half a century ago, after the appearance of local and systemic symptoms (abdominal and back pain, cholestasis, painless jaundice, fatigue, anorexia, weight loss, anemia, peripheral phlebitis, and cachexia)...

The craniopharyngiomas are solid cystic suprasellar tumors that can present extension to adjacent structures, conditioning pituitary and hypothalamic dysfunction. Within hypothalamic neuroendocrine dysfunction, we can find obesity, behavioral changes, disturbed circadian rhythm and sleep irregularities, imbalances in the regulation of body temperature, thirst, heart rate and/or blood pressure and alterations in dietary intake (like anorexia). We present a rare case of anorexia-cachexia syndrome like a manifestation of neuroendocrine dysfunction in a patient with a papillary craniopharyngioma...

Protein hypercatabolism significantly contributes to the onset and progression of muscle wasting in cancer cachexia. In this regard, a major role is played by the ATP-ubiquitin-proteasome-dependent pathway and by autophagy. However, little is known about the relevance of the Ca(2+)-dependent proteolytic system. Since previous results suggested that this pathway is activated in the skeletal muscle of tumor hosts, the present study was aimed to investigate whether inhibition of Ca(2+)-dependent proteases (calpains) may improve cancer-induced muscle wasting...

INTRODUCTION: Cancer cachexia is one of the most frequent effects of malignancy, is often associated with poor prognosis, and may account for up to 20% of cancer deaths. The aim of our study was to evaluate the relationship of cancer cachexia and serum levels of resistin and leptin in patients with advanced non-small cell lung cancer. METHODS: A total of 67 chemotherapy-naïve patients with advanced-stage non-small cell cancer and a control group containing 20 healthy individuals without a known chronic disease were enrolled in this study...

Cachexia, a progressive weight loss in cancer patients that results from tumor-induced energy wasting, is a serious problem that interferes with response to treatment and affects quality of life. Recent studies suggest that thermogenesis of adipose tissues is involved in energy wasting and also point to a link between the atrophy of fat and muscle. Tumor-derived PTHrP has emerged as a key molecule playing multiple roles in cachexia, from fat "browning" factor to potential therapeutic target.

Invited Letter to the Editor. Physical activity has multiple beneficial effects in the physiology and pathology of the organism. In particular, we and other groups have shown that running counteracts cancer cachexia in both humans and rodents. The latter are prone to exercise in wheel-equipped cages even at advanced stages of cachexia. However, when we wanted to replicate the experimental model routinely used at the University of Rome in a different laboratory (i.e. at Paris 6 University), we had to struggle with puzzling results due to unpredicted mouse behavior...
