Project description:Flaxseed (FS), a nutritional supplement consisting mainly of omega-3 fatty acids and lignan phenolics, has potent anti-inflammatory, anti-fibrotic and antioxidant properties. We have shown that dietary FS supplementation ameliorates oxidative stress and inflammation in experimental models of acute and chronic lung injury in mice resulting from diverse toxicants. The development of lung tissue damage in response to direct or indirect oxidant stress is a complex process, associated with changes in expression levels of a number of genes. We therefore postulated that flaxseed may modulate gene expression of vital signaling pathways, thus interfering with the development of tissue injury. We evaluated gene expression in lungs of flaxseed-fed (10% FS) mice under unchallenged, control conditions and 48hrs post-radiation treatment (13.5 Gy). Gene expression levels in lung tissues were analyzed using three arrays for each sample, whereby a total of 28,800 genes were evaluated. C57BL/6 black mice were fed a 10% flaxseed diet for 21 days and/or given 13.5Gy thoracic radiation and sacrificed 48hrs post radiation.

Project description:The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that buoys intestinal immune responses. AHR induces its own negative regulator, the AHR repressor (AHRR). Here we show that AHRR is vital to sustain intestinal intraepithelial lymphocytes (IEL). Fewer IEL of all types were present in the absence of AHRR. Single cell RNA sequencing (scRNAseq) revealed an oxidative cell stress profile in Ahrr–/– IEL. Ahrr deficiency unleashed AHR-induced expression of CYP1A1, an oxidative enzyme that generates reactive oxygen species; this resulted in elevated intracellular content of reactive oxygen species, lipid peroxidation and ferroptosis in Ahrr–/– IEL. Dietary supplementation with selenium or Vitamin-E (Vit-E) to restore redox homeostasis rescued Ahrr–/– IEL. Loss of IEL in Ahrr deficient mice caused susceptibility to Clostridium difficile infection and dextran sodium sulfate-induced colitis. We conclude that AHR signaling must be tightly regulated to prevent oxidative stress and ferroptosis of IEL to preserve intestinal immune responses.

Project description:Aging hampers the regenerative potential of intestinal epithelium across species including humans, yet the underlying causes remain elusive. Here, using proteomic and metabolomic profiling of intestinal tissues together with functional assays, we characterized the temporal dynamics of regeneration following injury induced by 5-fluorouracil, a commonly used chemotherapeutic agent. Comparison of regeneration dynamics in mice of different ages revealed the emergence of proteostasis stress and increased levels of polyamines following injury exclusively in old epithelia. We show that delayed regeneration is an intrinsic feature of aged epithelial cells that display reduced protein synthesis and accumulation of ubiquitylated proteins. Inhibition of the polyamine pathway in vivo further delays regeneration in old mice, while its activation by dietary intervention or supplementation of polyamines is sufficient to enhance the regenerative capacity of aged intestines. Our findings highlight promising epithelial targets for interventions aimed at tackling the decline in tissue repair mechanisms associated with aging.

Project description:Aging reduces the regenerative capacity of the intestinal epithelium in different species including humans. The causes of delayed regeneration in the elderly remain unclear. Here, we used proteomic and metabolomic profiling of intestinal tissues together with functional assays to characterize the dynamics of regeneration following injury induced by 5-fluorouracil, a commonly used chemotherapeutic agent. Comparison of regeneration dynamics in mice of different ages revealed emergence of a proteostasis stress signature and increased levels of polyamines following injury exclusively in old epithelia. Mechanistically, we show that delayed regeneration is a cell-intrinsic feature of old epithelial cells that display reduced protein synthesis and accumulation of ubiquitylated proteins. We demonstrate that an intervention based on dietary restriction followed by re-feeding prior to injury elevates intracellular polyamine levels, alleviates proteostasis stress and restores the regenerative capacity of the old intestines. Our work provides novel targets and strategies to improve intestinal regeneration in the elderly.
