A20 and TNIP-3 Reduce NF-κB-Mediated Paracrine Responses to Hypoxia/Hyperglycemia-Induced Endothelial Senescence

Hypoxia-induced senescence did not trigger a typical inflammatory SASP. Although ECs enter a senescent state, they activate an anti-inflammatory response, suppressing NF-κB signalling and increasing the expression of its inhibitors, A20 and TNIP-3. This may reflect a non-canonical senescence response whose functional significance remains to be determined.
