Dysregulated DNA Hydroxymethylation in Dyslipidemia-Related Apoptosis and Senescence

Previous Science Note

Scientists have discovered that obesity and dyslipidemia are linked to dysregulated DNA hydroxymethylation in apoptosis- and senescence-related genes in both swine and human MSCs. This dysregulation might impact cell vitality and regenerative capabilities. Vitamin C could mediate the reprogramming of this altered epigenomic profile, offering a potential approach to enhance the success of autologous MSC transplantation in obese patients.

Obesity and dyslipidemia are associated with partially reversible modifications to DNA hydroxymethylation of apoptosis- and senescence-related genes in swine adipose-derived mesenchymal stem/stromal cells

Point of Interest
- hMeDIP-seq identified 467 hyper- and 591 hypo-hydroxymethylated loci in swine Obese- versus Lean-MSCs.
- Combined hMeDIP-seq/mRNA-seq showed dysregulated genes related to apoptosis, cell proliferation, and senescence.  
- These changes were linked to increased senescence in MSCs and were partly reversed with Vitamin C.  
- Similar pathways were observed in human obese-MSCs.

Metabolic shift to glycolysis in senescenct cells

       

 

NAD(+) levels decline during the aging process, causing defects in nuclear and mitochondrial functions and resulting in many age-associated pathologies*. Here, we try to redemonstrate this phenomenon in the doxorubicin (DOX)-induced cellular senescence model with a comprehensive analysis of our products.
