Exploring the Protective Mechanisms of Chayote (Sechium edule) Juice in Mitigating Streptozotocin‐Induced Pancreatic Dysfunction

eFood, Volume 6, Issue 1, February 2025.
SEJ decreases apoptotic markers (caspase‐3, PARP, BAX) and inflammatory markers (NF‐κB, iNOS, NLRP3) in the pancreas and MINMIN‐6‐6 cells. SEJ enhances anti‐oxidant markers (Nrf‐2, HOHO‐1), contributing to its protective effects. Molecular docking shows that vicenin and 4‐O‐caffeoylquinic acid in SEJ have high binding affinities to key anti‐oxidant ...
