Project description:To study the response in the liver to cachectic and weight-stable cancer, we performed RNA-sequencing of whole liver nuclei and hepatocyte nuclei that were isolated using the INTACT methodology of weight stable NC26, pre-cachectic C26, cachectic C26, weight-stable MC38 and cachectic 8025 tumor bearing mice as well as their respective PBS controls.

Project description:The regulatory gene pathways underlying the loss of adipose tissue in cancer cachexia are unknown and were explored using pangenomic transcriptome profiling. Gene expression profiles (Human Gene 1.0 ST) of abdominal subcutaneous adipose tissue were studied in gastrointestinal cancer patients with (N=13) or without (N=14) cachexia. Data analyses were performed using the Affymetrix GeneChip Operating Software (GCOS) Version 1.4.

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:More than 85% of patients with pancreatic ductal adenocarcinoma (PDAC) suffer from cachexia, a debilitating syndrome characterized by loss of muscle and fat. To model PDAC cachexia in mice, 12-week-old C57BL/6J male mice were implanted with the cachexia inducing pancreatic cell line, KPC32908, into the pancreas. Controls underwent a sham surgery. Mice were euthanized under isoflurane anesthesia when the tumor-bearing mice exhibited cachexia, including ~18% loss of quadriceps mass versus sham controls. Quadriceps muscle was flash frozen at euthanasia. 1mg quadriceps protein lysate per sample was used for kinome profiling.

Project description:Pancreatic cancer is characterized by a high frequency of cachexia, pain and neural invasion (N-inv). Neural damage is occurred by N-inv and modulates pain and muscle atrophy via the activation of astrocyte in the connected spine. The activated astrocyte by N-inv, thus, may affect cachexia in pancreatic cancer. Clinical studies in patients and autopsy cases with pancreatic cancer have revealed that N-inv is related to cachexia and astrocytic activation. We established a novel murine model of cancer cachexia using N-inv of human pancreatic cancer cells. Mice with N-inv showed a loss of body weight, skeletal muscle, and fat mass without appetite loss, which are compatible with an animal model of cancer cachexia. Activation of astrocytes in the spinal cord connected with N-inv was observed in our model. Experimental cachexia was suppressed by disrupting neural routes or inhibiting the activation of astrocytes. These data provide the first evidence that N-inv induces cachexia via astrocytic activation of neural route in pancreatic cancer. We produced neural invasion (N-inv) model using intraneural injection of Capan-1 cells to left sciatic nerve of male SCID mouse. For controls, subcutaneous model (SC) and PBS model were produced. Microarray analysis was performed using the first lumbar cord (L1) from PBS, SC, and N-inv mice at 6 w (n = 2 each).

Project description:In this study, we sought to explore the importance of selected myokines in a homogenous population of patients with gastric cancer characterized by high rates of Cancer-Associated Cachexia [CAC]. Myokine levels in peripheral blood were compared between patients with and without cachexia to identify mediators potentially involved in the pathogenesis of CAC. Moreover, we compared myokine concentrations in paired samples of portal and peripheral blood to verify whether they are released by the primary tumour. Finally, a label-free quantitative proteomics was applied to explore other potential circulating mediators of CAC and to analyse their interactions with myokines.
