936 By inducing the expression of D-fructose-6-phosphate amidotransferase 1 in adjacent renal TECs, the flux of hexosamine biosynthesis pathway increases, and the level of BACH2 o-glycosylation modification rises, inhibiting its ubiquitination degradation

It was proposed (Casciola-Rosen et al., 1994) that the breaking of tolerance to autoantigens at the surface of apoptotic cells might be favored by oxidative modifications occurring as a result of the oxidative stress that characterizes apoptosis (Hockenberry et al., 1993)
