A-E Surface views (A-D) and z-sections (E) of third instar larval epidermis expressing the indicated fluorescent markers and RNAi or overexpression constructs. (A) Bazooka/Par3, normally seen at the apical adherens junction and in a perinuclear position, is lost or reduced in large areas under uncontrolled autophagy as are lateral membrane markers, (B) Fasciclin-III (FasIII), (C) neuroglian (Nrg) and (D) adherens junctions (DE-cad), whereas large bundles decorated with MRLC appear. (E) The baso-lateral transmembrane protein β-integrin is not lost; in extreme conditions, it is seen in both the apical and basal membranes (overexpression of Atg16B). Arrows in the z-sections point to high accumulation of integrin along the folded lateral membranes
