Figure 3: Right cervical vagotomy attenuates behavioral abnormalities and enhances chemotherapy response in lung (LLC) or orthotopic pancreatic (KPC) cancer.

A. Spontaneous motion over 15 minutes in open field assay and socialization in three chamber social assay. WT controls are the same for each cancer cohort. N=48 (8 animals per group). B. Quantification of daily food consumption from cage top feeder. WT controls are the same for each cancer cohort. N=48 (8 animals per group). C. Survival curve showing longitudinal survival of LLC- or KPC-injected mice receiving sham surgeries or vagotomy with or without chemotherapy. Statistical significance by Peto’s Log Rank Test with Bonferroni correction for multiple comparisons (6-fold). D. Weight changes in LLC or KPC bearing-mice which received sham surgeries or vagotomy with or without chemotherapy. N=64 (8 animals per group). Analysis by RMANOVA with Tukey HSD. E. Tumor burden measurements at time of sacrifice in tumor bearing-mice which received sham surgeries or vagotomy with or without cisplatin chemotherapy. N=64, 8 mice per group. F-G. Impacts of hexamethonium, atropine, or PBS treatment in KPC or LLC mice and WT controls on (F) weight loss and (G) survival. N=56, 8 per condition. Statistical significance for survival by Peto’s Rank-Log test with 3x Bonferroni correction. Statistical analysis by ANOVA with Tukey Post-Hoc unless otherwise stated. For all box plots, dots represent data collected from unique mice. For all tests, * represents p<0.05, ** represents p<0.01, *** represents p<0.001, **** represents p<0.0001. See also Figure S2–S4.
