Aryl hydrocarbon receptor-dependent and -independent pathways mediate curcumin anti-aging effects

Project description:In this study we investigated if curcumin has AhR-dependent effects on aging. This transcriptomic analysis should help shed light on the AhR-dependent and AhR-independent mechanisms of curcumin.

Aryl Hydrocarbon Receptor-Dependent and -Independent Pathways Mediate Curcumin Anti-Aging Effects.

Project description:The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor whose activity can be modulated by polyphenols, such as curcumin. AhR and curcumin have evolutionarily conserved effects on aging. Here, we investigated whether and how the AhR mediates the anti-aging effects of curcumin across species. Using a combination of in vivo, in vitro, and in silico analyses, we demonstrated that curcumin has AhR-dependent or -independent effects in a context-specific manner. We found that in Caenorhabditis elegans, AhR mediates curcumin-induced lifespan extension, most likely through a ligand-independent inhibitory mechanism related to its antioxidant activity. Curcumin also showed AhR-independent anti-aging activities, such as protection against aggregation-prone proteins and oxidative stress in C. elegans and promotion of the migratory capacity of human primary endothelial cells. These AhR-independent effects are largely mediated by the Nrf2/SKN-1 pathway.

Aryl hydrocarbon receptor antagonism allows sustained culture of leukemia progenitor cells from acute myeloid leukemia patients

Project description:Hematopoietic progenitors from AML patients express the aryl hydrocarbon receptor signaling pathway. Independent of in vivo engraftability to detect leukemic stem cells, AHR antagonism allows in vitro survival and expansion of AML progenitors, while retaining patient-to-patient heterogeneity. Based on AML expression data, we show that AHR antagonism disrupts the AHR signaling pathway but it doesn't affect the overall genomic profile of the samples

Effect of canonical aryl hydrocarbon receptor pathway inhibitor on human endothelial cells

Project description:To study the effect of blockade of canonical aryl hydrocarbon receptor (AHR) pathway in human endothelial cells, we treated human umbilical vein endothelial cells (HUVECs) and adipose endothelial cells with a canonical AHR inhibitor, Stemreginin 1 (SR1) and performed bulk RNAseq analysis.

Expression data of primary melanocytes from aryl hydrocarbon deficient mice and corresponding wild-type C57BL/6 mice

Project description:[original Title] Comparison of expression data of primary murine melanocytes from aryl hydrocarbon deficient mice and corresponding wild-type C57BL/6 mice Melanin is produced exclusively by melanocytes and melanogenesis is the vital response to protect skin cells against Ultraviolet B (UVB)-induced DNA damage. The aryl hydrocarbon receptor (AhR) is a transcription factor, which may be involved in the physiological tanning response. Normal murine melanocytes express functional AhR. We tested gene expression in WT versus AhR-deficient mice primary murine melanocytes, isolated from the skin and cultivated for several passages. Skin epidermal cells from 2 individual C57BL/6 mice and 2 individual AhR-deficient mice (deletion of exon2, AhRtm1Bra) were grown for 6-8 weeks in selection medium to propagate melanocytes.
