Cells were treated with 1μM GCB for 48 hours, & after fixation, cells were stained with anti-LC3 antibody & analyzed by fluorescence confocal microscopy. GCB increases the number of green punctae in the treated group as compared to the untreated. D. Expression of BECN, LC3, & p62 was analyzed using Western blot analysis. Cells were treated with GCB for 48 hours, lysed & extracted protein was analyzed using specific antibodies. beta-actin was used as a loading control. Autophagy induction is demonstrated by an increase in the conversion of LC3I to LC3II, BECN expression & a decrease in p62 expression in the treated group as compared with the untreated. E. Treatment of OS cells with GCB (1μM, 48 hours), led to an increase in the formation of autophagic vacuoles (shown with red arrows) measured by transmission electron microscopy.

(F) Anp, Bnp, beta‐MHC, c‐TnI & GATA4 mRNA levels in hearts by real‐time RT‐PCR, calculated as ratio to beta‐actin mRNA & expressed relative to WT. (G) Western blots of cardiac tissue extracts & mouse embryonic cardiomyocytes (MECs) showing ANP, BNP, GATA4, LC3B & p16; beta‐actin was the loading control. (H) Protein levels relative to beta‐actin were assessed by densitometric analysis. (I) Representative micrographs of paraffin‐embedded heart sections immunohistochemical staining for ANP, BNP & GATA4. (J) The percentage of cells positive for ANP, BNP, GATA4 or positive area relative to total cells or area. (K) Representative micrographs of fluorescence with autophagy lentivirus transfection, with DAPI for nuclei. (L) Percentage of positive GFP dots or mRFP dots relative to total cells. (M) The number of autophagosomes & autolysosomes per cell. Six mice per group were used for experiments. Cell experiments were performed with three biological repetitions per group. Values are mean ± SEM from six determinations per group, *p < .05, **p < .01, ***p < .001 compared with WT group, unpaired Student's t‐test Image collected & cropped by CiteAb from the following publication (https://pubmed.ncbi.nlm.nih.gov/35390228), licensed under a CC-BY license.

Western Blot: LC3B Antibody - BSA Free [NB600-1384] - 8-Cl-Ado-induces autophagy. Immunoblot analysis of (A) phospho-ULK (Ser555) levels & (B) LC3B-I lipidation to form LC3B-II in MCF-7 & BT-474 cells treated with 10 μM of 8-Cl-Ado for the indicated times. (C) Fluorescent microscopy of MCF-7 & BT-474 cells transiently transfected with GFP-LC3B & treated with 10 μM of 8-Cl-Ado for 12-hours to assess aggregation of LC3B. (D) Immunoblot analysis of p62 levels in MCF-7 & BT-474 cells treated with 10 μM of 8-Cl-Ado for the indicated times. The normalized ratio of p62 to GAPDH relative to the untreated control is indicated beneath each lane. (E) Fluorescent microscopic imaging of autolysosomes. MCF-7 cells were untreated or treated for 2-days with 8-Cl-Ado or rapamycin. Cells were stained with MDC, blue, to visualize AVO & Syto 61 (DNA), red, for nuclei counterstaining. (F) Representative flow cytometery histograms of AVO stained with acridine orange in MCF-7 cells untreated or treated for 3 days with 50 nM rapamycin or 10 μM 8-Cl-Ado. Baf was added before 30 min prior to staining to neutralize AVO staining. (G) Quantification triplicate experiments of MCF-7 & BT-474 cells treated & analyzed as in E.
