Project description:Cachexia is a wasting syndrome characterized by pronounced skeletal muscle loss. In cancer, cachexia associates with increased morbidity and mortality and decreased treatment tolerance. Although advances have been made in understanding the mechanisms of cachexia, translating these advances to the clinic has been challenging. One reason for this shortcoming may be the current animal models that fail to fully recapitulate the etiology of human cancer-induced tissue wasting. Because pancreatic ductal adenocarcinoma (PDA) presents with a high incidence of cachexia, we engineered a mouse model of PDA, that we named KPP. KPP mice, similar to PDA patients, progressively lose skeletal and adipose mass as a consequence of their tumors. In addition, KPP muscles exhibit a similar gene ontology to cachectic patients. We envision the KPP model will be a useful resource for advancing our mechanistic understanding and ability to treat cancer cachexia.

Project description:Cancer cachexia syndrome is observed in 80% of patients with advanced-stage cancer, and it is one of the most frequent causes of death. Severe wasting accounts for more than 80% in patients with advanced pancreatic cancer. Here we wanted to define, by using an microarray approach and the Pdx1-cre;LSL-KrasG12D;INK4a/arffl/fl, the pathways involved in muscle, liver and white adipose tissue wasting. The aim of our work was to characterize as extensively as possible the pathways activated by the pancreatic cancer-induced cachectic tissues. For this purpose, we generated and compared genome-wide expression profiles of white adipose tissue, skeletal muscle and liver, from Pdx1-cre;LSL-KrasG12D;INK4a/arffl/fl and LSL-KrasG12D;INK4a/arffl/fl mice at 10 weeks-old. Tissue samples by triplicate was obtained from liver, muscle and adipose tissues in both groups, controls and cachectic mice. Total RNA samples was processed and profiled on Affymetrix Mouse Gene 1.0 ST arrays as previously described (Cano et al, 2012)

Project description:Cancer cachexia is a prevalent and often fatal wasting condition that cannot be fully reversed with nutritional interventions. Muscle atrophy is a central component of the syndrome, but the mechanisms whereby cancer leads to skeletal muscle atrophy are not well understood. We performed single nucleus multi-omics on skeletal muscles from a mouse model of cancer cachexia and profiled the molecular changes in cachexic muscle. Our results revealed the activation of a denervation-induced gene program that upregulates the transcription factor myogenin. Further studies showed that a myogenin-myostatin pathway promotes muscle atrophy in response to cancer cachexia. shRNA inhibition of myogenin or inhibition of myostatin through overexpression of its endogenous inhibitor follistatin prevented cancer cachexia-induced muscle atrophy in mice. Our findings uncover a molecular basis of cancer cachexia-induced muscle atrophy and highlight potential therapeutic targets for this disorder.

Project description:Cachexia is an exacerbating event in many types of cancer that is strongly associated with a poor prognosis. We have identified cytokine, signaling and transcription factors that are required for cachexia in the mouse C26 colon carcinoma model of cancer. C2C12 myotubes treated with conditioned medium from C26 cancer cells induced atrophy and activated a STAT-dependent reporter gene but not reporter genes dependent on SMAD, FOXO, C/EBP, NF-ĸB, or AP-1. Of the gp130 family members IL-11, IL-6, oncostatin M (OSM), and leukemia inhibitory factor (LIF), only OSM and LIF were sufficient to activate the STAT reporter in myotubes. A LIF blocking antibody abolished C26 CM-induced STAT reporter activation STAT3 phosphorylation and myotube atrophy, but blocking antibodies to IL-6 or OSM did not. JAK2 inhibitors also blocked the C26 CM-induced STAT reporter activation, STAT3 phosphorylation, and atrophy in myotubes. LIF at levels found in the C26 CM was sufficient for STAT reporter activation and atrophy in myotubes. In vivo, an increase in serum LIF preceded the increase in IL-6 in mice with C26 tumors. Overexpression of a dominant negative Stat3Cβ-EGFP gene in myotubes and in mouse muscle blocked the atrophy caused by C26 CM or C26 tumors, respectively. Taken together these data support an important role of LIF- JAK2-STAT3 in C26 cachexia and point to a therapeutic approach for at least some types of cancer cachexia. from three replicate wells of cells at each treatment, pools of total RNA were used to create cDNA which were evaluated on Affymetrix mouse gene 1.0 ST v.1 arrays.

Project description:The mechanisms underlying exercise-induced effects in the skeletal muscle during cancer cachexia progression have not been fully described. Here, we tested the hypothesis that different exercise training protocols could attenuate metabolic impairment in a severe model of cancer cachexia. Moderate-intensity training (MIT) and high-intensity interval training (HIIT) improved running capacity and prolonged lifespan in tumor-bearing rats. HIIT also reduced oxidative stress and reestablished muscle contractile function. An unbiased proteomics screening revealed that COP9 signalosome complex subunit 2 (COPS2), also known as thyroid receptor interacting protein 15 (TRIP15) or ALIEN, is one of the most downregulated proteins at the early stage of cancer cachexia progression. HIIT restored COPS2/TRIP15/ALIEN protein expression to the control levels. Moreover, lung cancer patients with low endurance capacity had lower muscle COPS2/TRIP15/ALIEN protein content compared to age- and sex-matched control subjects. We further established an in vitro model of cancer-induced muscle wasting using tumor cells-conditioned media to explore the potential protective role of COPS2/TRIP15/ALIEN for myotubes homeostasis. This in vitro model indicate that tumor cells produce factors that directly affect myotube metabolism, but COPS2/TRIP15/ALIEN overexpression is not able to fully reestablish metabolic homeostasis and protein content in myotubes incubated with tumor cells-conditioned media. The current study provides new insight into the role of exercise training as a co-therapy for cancer cachexia and uncovers COPS2/TRIP15/ALIEN as a novel potential target for cancer cachexia.

Project description:Cachexia frequently develops in patients with pancreatic ductal adenocarcinoma (PDAC) and contributes to cancer deaths.Sex differences have been observed in cancer cachexia; however, the underlying molecular mechanisms are far less addressed. We assessed sex difference in PDAC cachexia phenotypes in the KPC (Kras-G12D;Trp-R172H;Pdx1::Cre) genetically engineered mouse model of PDAC and profiled gene expression in the quadriceps skeletal muscles. Males with PDAC experienced earlier cachexia-onset than the female counterpart and activin blockade by ACVR2B/Fc reduced cachexia sympotomes in males but not females. PDAC induced earlier global transcritome alterations in males than females.
