Animal trials show reduced ulcer severity and improved mucosal healing, but translating this to human benefit remains unproven

We thus hypothesize that vitamin B 12 deficiency may have a secondary, indirect effect, one which inhibits the conversion of cystathionine to cysteine

This could be the main damage of the photodynamic action, leading to bacterial death through leakage of cellular contents or inactivation of membrane transport systems and enzymes (Caminos et al., 2008

Further, the interaction between CHAC1 and the ATF4-CHOP pathway elucidates a feedback loop where oxidative stress enhances ER stress, which in turn aggravates oxidative stress through CHAC1-mediated GSH depletion
