Abstract

New Findings: What is the central question of this study? What are the alleviative effects of the combination of exercise training and quercetin supplementation on colorectal cancer‐related depression in rats with 1,2‐dimethylhydrazine‐induced colorectal cancer and what is the corresponding signalling pathway? What is the main finding and its importance? We showed that the combination of exercise training and quercetin supplementation resulted in a significant decrease in tumour incidence and improvement in depressive‐like behaviours through modulation of the BDNF/TrKβ/β‐catenin axis in the prefrontal cortex. In addition to physical problems, depression is considered to be one of the most important challenges for patients with various types of cancers, particularly colorectal cancer. Inflammation and upregulation of brain neurotrophic factors are two major links between cancer and depression. In this study, we aimed to evaluate the alleviative effects of quercetin and exercise training on depressive‐like behaviours in rats with 1,2‐dimethylhydrazine (DMH)‐induced colorectal cancer and to investigate the underlying mechanisms. Animals were assigned into the following five groups: (i) control group; (ii) DMH (20 mg kg−1s.c., once a week for 10 weeks); (iii) DMH for 10 weeks, followed by quercetin (50 mg kg−1p.o., once per week) for 12 weeks; (iv) DMH for 10 weeks, followed by exercise training for 12 weeks; and (v) DMH for 10 weeks, followed by quercetin and exercise training for 12 weeks. The DMH‐treated rats showed an increase in depressive‐like behaviours in both open field and forced swimming tests. Histopathological examination revealed neural damage and reduced Nissl bodies in the prefrontal cortex. In addition, administration of DMH increased inflammatory cytokines in the serum, prefrontal cortex and tumour tissues and decreased the expression levels of brain‐derived neurotrophic factor (BDNF), tyrosine kinase β receptor (TrKβ) and β‐catenin in the cortex. In contrast, treatment with quercetin and exercise training effectively alleviated all the above‐mentioned DMH‐associated behavioural, biochemical and histopathological alterations without changing its anti‐tumour activity. Taken together, our results show that the combination of quercetin and exercise training exerts potent anti‐tumour and anti‐depressive effects through suppression of inflammation and upregulation of the BDNF/TrKβ/β‐catenin axis in the prefrontal cortex.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
