In addition, we also quantitatively analyzed both groups for the expression of apoptosis-related (BAD, BAX, BCL2L10, and XIAP) and autophagy-associated (HAX1 and Beclin-1) marker proteins, since both signaling cascades are supposed to be highly involved in the molecular pathogenesis of glaucoma (21). The gene discussed is XIAP; the disease is glaucoma.
