![Western Blot: LC3A Antibody - BSA Free [NB100-2331] - UBC9 is degraded by autophagy in epithelial cells.(A) Immunolocalization of UBC9 in ultrathin sections of HKs transduced with empty or HPV16 E6/E7 vectors. Original view (left) & higher magnification (right) of boxed regions. Gold particles are selectively enriched in autophagic structures highlighted by arrows. Scale bar = 1 μm. (B) Top: Representative WB of HaCaT cells treated with the indicated autophagic activators (left) & inhibitors (right). Activation of autophagy was monitored by the conversion of LC3 (LC3-I) to the lipidated LC3 (LC3-II) form, a marker of autophagosome production induced by autophagic stimuli [41]. LC3-II accumulation was used to verify autophagic impairment [41]. Bottom: normalized UBC9 expression. Data are expressed as fold over untreated cells. Bars represent means ± SEM of n = 4 different biological replicates. ns: not significant (Kruskal–Wallis one-way ANOVA with Dunn’s post hoc test) compared to vehicle control groups. (C) Representative WB analysis of U-2 OS or MCF7 cells treated with chloroquine. n = 3 different biological replicates. (D) Representative WB analysis of MCF7 cells transduced with scramble or ATG5 shRNA. The observed ATG5 band represents the ATG5-ATG12 conjugated form. LC3-I accumulation is reported to evidence autophagic deficiencies promoted by shATG5. n = 3 replicates of a single transduction.

Results are accumulated from two independent experiments & represented by scatter & boxplots as detailed in the “Methods” section. ns non-significant, *p 10 larvae/sample). Lc3 c & e, or p62 & Optineurin d protein levels were detected in absence or presence of BafA1, c & d, or in the presence or absence of Mm e. Actin was used as a loading control. Western Blots were repeated three, c & d, or two e times with protein extracts derived from independent experiments. The Lc3II/Actin or p62/Actin & Optineurin/Actin ratio, normalized to the control sample, is indicated below the blots. f–g Representative confocal micrographs & quantification of GFP-Lc3 co-localization with Mm clusters in infected dram1∆19n/∆19n & dram1+/+ larvae. The top images f show the entire region of imaging, while the bottom images f′ & f″ show details of GFP-Lc3 colocalization of Mm clusters in dram1∆19n/∆19n & dram1+/+ larvae.

![Western Blot: LC3A Antibody - BSA Free [NB100-2331] - Knockdown of FUT1 is associated with an increase in autophagic flux. (a) Immunoblot analysis of LC3-II & p62 levels in control & FUT1 knockdown cells. Total cell lysates from MCF-7 & T47D cells transfected with control or FUT1 siRNAs were collected at 120 & 96 h post-transfection, respectively. Equal amounts of cell lysates were then loaded in each lane & separated by SDS-PAGE. Immunoblot analysis was performed with LC3 & p62 antibodies. Actin was used as a loading control. The intensity of LC3-II & p62 protein bands on immunoblot were quantified & normalized to actin, & the relative levels of protein expression were expressed as fold change by setting the control group value to 1. Values shown are mean±S.E.M. of three independent experiments (***P100 cells per group (*P<0.05) Image collected & cropped by CiteAb from the following publication (//pubmed.ncbi.nlm.nih.gov/27560716), licensed under a CC-BY license.

![Western Blot: LC3A Antibody - BSA Free [NB100-2331] - Effect of MIR376A overexpression on autophagy.(A) MCF-7 cells were co-transfected with either MIR-CNT (control plasmid) or MIR376A & GFP-LC3 plasmid, & GFP-LC3 dot formation was analyzed. White arrows indicate clusters of the GFP-LC3 dots in cells. (B) Quantification of the experiments in A. MIR376A overexpression, but not MIR-CNT expression, blocked starvation (STV)-induced autophagy (mean ± S.D. of independent experiments, n = 4, ***p<0,01). NON STV, non-starved (C) Overexpression of MIR376A resulted in a decrease in the autophagic activity of MCF-7 cells. Starvation-induced conversion of LC3-I to LC3-II in MCF-7 cells was analyzed. Tests were performed in the presence or absence of E64d (10 µg/ml) & Pepstatin A (10 µg/ml) (E+P). LC3-II/LC3-I densitometric ratios were marked. ACTB was used as a loading control. (D) MIR376A blocked starvation induced SQSTM1 degradation in MCF-7 cells. ACTB was used as a loading control. SQSTM1/ACTIN densitometric ratios were marked.

![Western Blot: LC3A Antibody - BSA Free [NB100-2331] - Tau clearance in vivo & autophagy function. Clearance kinetics of photoconverted Dendra-tau measured in neurons of WT-tau & AT152T-tau fish. Measurement of intensity of red Dendra-tau signal over time reflects the clearance or degradation of tau protein. (C–F) WBs for LC3-II, a well-characterized marker of autophagosome number, demonstrate that there no differences in levels of this protein between WT-tau & A152T-tau fish either at 24 hpf (pre-phenotype; C & D) or 72 hpf (post-phenotype; E & F). (E & F) Measurements of LC3-II levels in presence or absence of ammonium chloride provides a method for measuring autophagic flux. No differences observed between the two transgenic lines at 3 dpf, suggesting that autophagy functions normally in both WT-tau & A152T-tau fish (graph represents mean ± SD of four independent clutches per group for E & F & 3for C & D; two-tailed t-test).
