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 (***P<0.001; **P<0.01; *P<0.05). (b) Downregulation of FUT1 enhanced the fusion of autophagosome & lysosomes in MCF-7 cells. Cells were co-stained with anti-LAMP-1 (green) & anti-LC3 (red) & nuclei stained with Hoechst (blue). Representative colocalization signals (referred to as autolysosomes) were shown in yellow in the merged. Magnification × 63, zoom: × 3. Scale bars, 10 μm. Histogram shows the percentages of autolysosomes (LC3+/LAMP-1+) to autophagosomes (LC3+/LAMP-1−). Data are mean±S.E.M. of three independent experiments of >100 cells per group (*P<0.05) Image collected & cropped by CiteAb from the following publication (https://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).
