Figure 9.(A) Quantitation of autophagy in HeLa cells. Cells were either grown in complete medium (1), treated with IFN-γ (1,000 U/ml) (2), or treated with IFN-γ in the presence of the broad caspase inhibitor BD-fmk (100 μM) (3) for 3 d. (B) Photographs of the MDC-stained HeLa cells corresponding to the experiment in A. Treatments: complete medium (1), IFN-γ (1,000 U/ml) (2), and IFN-γ (1,000 U/ml) + BD-fmk (3).(C) PARP cleavage in HeLa IFN-γ-treated cells. Proteins extracted from IFN-γ-treated (left) or TNF-α-treated (100 ng/ml) cells (right) were subjected to Western blot analysis with anti-PARP antibodies. The proteins were prepared from the same experiment shown in A.(D) Transmission electron micrographs of nontreated (top) and IFN-γ-treated (bottom) HeLa cells. Arrows point to autophagic vesicles.(E) DAPk antisense-transfected and control DHFR-transfected polyclonal populations of HeLa cells were incubated with hygromycin B (200 μg/ml) in the presence or absence of IFN-γ (1,000 U/ml) and BD-fmk (50 μM). Detection of autophagic vesicles was performed 2 d later using the MDC dye. Graphs represent mean ± SD of MDC-positive cells calculated from triplicates of 100 cells each.
Figure 10.DRP-1 is localized to the lumen of autophagic vesicles. Immunogold staining of 293 cells expressing HA-DRP-1 reveals a specific staining of DRP-1 in the lumen of double membrane autophagosomes containing cytoplasmic material (A and B) in autophagosomes containing organelles and vacuoles (C) and inside the body of autolysosomes containing digested matter (D). The gold particles do not overlap with the phagocytosed organelles in C or the lysosomes in D.
Figure 3(A-C) Embryos co-expressing the optogenetic module and Sqh::mCherry mounted with the ventral epithelium facing the objective were subjected to cycles of photo-activation of the cell base in the anterior (left) half of the embryo and confocal recording of the whole embryo. The experiment was started at the end of cellularization when initial accumulation of apical myosin-II was detected and terminated at different time points to record the plasma membrane signal (CIBN::GFP-pm) in the whole embryo using two-photon illumination. Still frames visualizing the plasma membrane (CIBN::GFP-pm) at a sub-apical plane at the initial time point of the experiment (A), 3 min (B) and 10 min (C) after initial photo-activation.
Figure 5 (C-E) Embryos expressing either of the optogenetic anchor proteins and RhoGEF2-CRY2::mCherry were imaged during late cellularization. (C) z-projections of confocal image stacks show the localization of the respective GFP-tagged optogenetic anchor. Please note that the construct PatJ-CIBN (indicated by asterisk) lacks a fluorescent marker and its localization was thus inferred from the recruited RhoGEF2-CRY2::mCh. All anchor proteins showed predominantly basal localization during cellularization and at the onset of ventral furrow formation. Scale bars, 20 μm. (D) A region of interest (right side of the dashed line) in a 10 µm-sized stack was photo-activated using two-photon illumination for 30 s before acquiring the RhoGEF2-CRY2::mCherry signal using confocal microscopy. All anchor proteins were able to recruit RhoGEF2-CRY2::mCherry specifically to the activated region. Scale bars, 10 μm. (E) Although all basal anchors were effective at recruiting RhoGEF2-CRY2::mCherry to the cell base, only PatJ-CIBN::GFP-pm resulted in effective myosin-II recruitment and actomyosin ring constriction
Figure 6(A) Localization of the basal-specific optogenetic anchor CIBN-PatJ::GFP-pm during ventral furrow formation. Embryos expressing CIBN-PatJ::GFP-pm were imaged using two-photon excitation during ventral furrow formation. Transverse cross section (z-projection) at a stage when cells were already apically constricted and elongated, and the ventral tissue already internalized.Embryos co-expressing CIBN-PatJ::GFP-pm, RhoGEF2-CRY2 and Sqh::mCherry (B,C were mounted with the ventral tissue facing the objective. After cells underwent apical constriction and cell elongation the basal volume of the ventral cells was photo-activated using two-photon illumination and the myosin-II signal was recorded in alternation. (B) myosin-II distribution in a cross section (z-projection) 3 min after photo-activation. myosin-II was locally recruited to the base as indicated by the red arrowheads in the activated region (red line). (C) Top view (sum of slice of 4 µm-sized image stack) showing basal myosin-II recruitment in the photo-activated region (red dashed square) Data information: Scale bars, 20 µmEmbryos co-expressing CIBN-PatJ::GFP-pm, RhoGEF2-CRY an the membrane marker GAP43::mCherry (D-I) were mounted with the ventral tissue facing the objective. After cells underwent apical constriction and cell elongation the basal volume of the ventral cells was photo-activated using two-photon illumination and the myosin-II signal was recorded in alternation (D) Cross section (z-projection) showing the plasma membrane and (E) top view showing the apical plasma membrane at the initial time point before photo-activation. At this stage, the central mesodermal tissue has started to internalize and cells were constricted at the apical surface. In an alternating fashion, the base of the cells in the anterior half of the embryo (left) was photo-activated for 100 sec and the GAP43::mCherry signal in the entire field of view was recorded. The furrow further ingressed and closed completely 3 min (F) and 6 min (G) after initial activation, respectively. In the activated region, the tissue failed to internalize and to form a closed furrow both at 3 min (H) and 6 min (I) after initial photo-activation. The width of the central tissue forming the ventral furrow at the initial point of the experiment is 40 µm (D). In the non-activated region 6 min after initial activation the width of the tissue shrank to about 25 µm (G), whereas it remained constant at 40 µm in the activated region (I). Data information: Scale bars, 20 µm
