It targets substrates like long-lived proteins, aggregate-prone proteins, and damaged organelles for lysosomal degradation to maintain cellular homeostasis 12.

This process is conserved across uAtophagy and involves the formation of double-membraned structures known mariers autophagosomes. The double-membraned autophagosomes form from cup-shaped maekers known as phagophores Aurophagy are makrers for the engulfment Autophzgy cargoes that are subsequently markerrs after fusion with lysosomes markere.

These types of assays have been used for Ahtophagy and marmers screens and for assessing autophagy status both in Energy-boosting pre-workout and in vivo in different Autopahgy.

With such assays, the mafkers or Autpphagy overall area of LC3-positive Pancreas anatomy can increase, if there is increased autophagosome formation or impaired degradation. However, it has been mmarkers that the numbers of LC3-positive structures and markerz area should decrease if autophagosome biogenesis is impaired and that there should be no LC3-positive structures in cells mar,ers LC3-II cannot form.

Autoophagy, we find that these assumptions are incorrect, as we show that LC3-I Endurance sports nutrition tips Time-restricted eating associated with ppositive aggregates, which Autopahgy known to accumulate Essential oils for acne form inclusion bodies when autophagy is compromised 6Markdrs.

However, while marers existing magkers shows Autiphagy formation of LC3-positive structures AAutophagy GFP-LC3 jarkers in autophagy-null cells from mice MEFs 9101112we show that endogenous LC3-I in ATG9- and ATG16L1-knockout cells of human origin HeLa cells forms distinct ubiquitin-positive aggregates in association with p More importantly, we show that this phenomenon occurs even under partial autophagy-deficient conditions after transient knockdown of essential autophagy genes, such as ATG7 and ATG The conditions of transient autophagy-deficiency in cells that occurs when using siRNA-mediated depletion also forms the underlying basis for many experimental strategies, such as drug screening assays in the field of autophagy.

Therefore, these data have critical implications for interpreting one of the most widely used set of autophagy assays. While characterising ATG9 CRISPR knockout HeLa cells Supp. This was associated with a clear increase in LC3-I in ATG9 knockout cells Supp.

These phenotypes were rescued when the ATG9 null cells were transfected with ATG9A-GFP Supp. To confirm this observation, we used LC3 immunocytochemistry Fig. Interestingly, the ATG9 knockout cells had fewer, but much larger LC3-positive structures, compared to control cells Fig. This phenotype was also rescued by transfection of the ATG9-null cells with ATG9A-GFP Fig.

d Representative images showing the rescue of the phenotype observed in ATG9-knockout cells using ATG9A-GFP construct. g Representative immunofluorescence images showing LC3 staining in ATG16L1 control and knockout cells.

ATG16 control and knockout cells were fixed with methanol and labelled for endogenous LC3. We next studied ATG16L1 knockout HeLa cells 13 that have no LC3-II Supp.

Surprisingly, these cells also had large LC3-positive structures, compared to control cells Fig. LC3-positive structures become more prominent in control cells after treatment with lysosomal pH-modulating autophagy inhibitors that compromise autophagosome degradation, like bafilomycin A1 and ammonium chloride.

However, lysosomal alkalinisation did not alter the LC3-positive structures in the ATG16L1-null cells Fig. To test whether the above observation could be replicated under conditions of acute autophagy knockdown in WT HeLa cells, we depleted ATG7 and ATG10 using siRNA-mediated knockdown Fig.

As expected, the LC3-II levels decreased upon ATG7 and ATG10 knockdown in the absence and presence of bafilomycin A1 Fig. However, the total number of LC3-positive structures and the total area of the LC3-positive structures increased after siRNA-mediated depletion of ATG7 and ATG10 Fig.

To ensure that the observed effect of ATG7 and ATG10 knockdown was not artefactual, we performed a rescue of the phenotype using overexpression of ATG7 and ATGFLAG constructs. Our results showed that the knockdown phenotype was rescued upon overexpression of ATG7 and ATG10 constructs Supp Fig.

The statistical analysis was performed using one-tailed paired t-test. Error bars represent standard error of the mean SEM. As ATG16L1-null cells form LC3-positive structures, we confirmed whether LC3-I is capable of forming distinct structures in cells using non-conjugatable forms of LC3 tagged with GFP at the N-terminus of the protein.

The conjugation of LC3-I to phosphatidylethanolamine can be abolished by mutating glycine to alanine LC3-GA to abrogate the ubiquitin-like reaction 14 LC3 with this mutation can exist as pro-LC3 and LC3-I forms in the cell. However, LC3-GA-ΔC22, where the glycine to alanine mutation is combined with deletion of 22 amino acids located beyond the C-terminal alanine residue mimicking the ATG4 reactionmimics LC3-I Both of these mutants formed prominent structures in ATG9 null or ATG16L1 null cells Fig.

Furthermore, overexpression of non-conjugatable mutant forms of other LC3-family members such as GFP-GABARAP-GA and GFP-GABARAP-L1-GA in ATG16L1 KO cells resulted in the formation of structures similar to the ones described above Supp. These findings demonstrate the formation of LC3-positive puncta in autophagy-impaired cells, even under conditions where the process of LC3-lipidation is completely abrogated, and other members of LC3-family behave in a similar fashion under autophagy-impaired conditions.

Importantly, these p62 structures appeared to be ubiquitinated Fig. Interestingly, since a recent study suggests that increased levels of LC3 inhibit the growth of p62 aggregates 16we therefore decided to further investigate the association of LC3 with p Super-Resolution Structured Illumination microscopy SR-SIM showed a clear association between LC3 and p62 structures Fig.

These p62 structures were much smaller in size in the ATG9-knockout cells compared to ATG16L1-knockout cells, which might be due to presence of some residual autophagy in ATG9-knockout cells.

Moreover, some ATG16L1-knockout cells had extremely large p62 structures associated with little LC3. Our impression was that smaller p62 structures appeared to have more LC3, compared to larger ones Fig.

These findings suggest that the LC3- and ppositive structures present in autophagy-null cells may be aggregates. a Representative immunofluorescence images showing the co-localization of LC3-positive structures in autophagy-deficient ATG9 and ATG16L1 knockout cells with p62 using co-localisation profile generation.

c Representative super-resolution immunofluorescence images showing the co-localization of LC3-positive structures with larger p62 aggregates in ATG16L1 knockout cells. Scale bars have been labelled individually for each magnification. To confirm that the p62 structures in autophagy-impaired cells are indeed aggregates, as they co-localised with ubiquitin, we performed a rapid detergent extraction of the membranes in ATG16L1-knockout cells transfected with ppEGFP and RFP-LC3 Fig.

While the extraction results in the rapid loss of the RFP-LC3 signal within few seconds after addition of 1. Moreover, upon separation of the cell lysates into soluble and insoluble fractions, LC3-I as well as p62 were observed to be associated with the insoluble fraction in ATG16L1-knockout cells Fig.

These findings demonstrate that LC3-I is sequestrated by p62 aggregates in autophagy-impaired cells. a Representative series of images depicting the live-cell imaging of cells during the detergent extraction experiment using 1.

The blot also shows the lack of ATG16L1 expression in ATG16L1-CRISPR knockout cells and a corresponding increase in the p62 levels in these cells.

Please refer to Supplementary Information File for full-length blots. We then tried to investigate whether the binding of LC3 and p62 is required for the formation of these LC3-positive structures observed in autophagy-impaired cells.

We first excluded the possibility that our results are due to increased binding between LC3 and p62 in ATG9- and ATG16L1-knockout cells by overexpressing GFP-LC3 and performing GFP-trap assays to pull-down GFP-LC3 and probing for p62 levels.

We observed no changes in the binding of LC3 to p62 in ATG9-knockout cells, whereas we found impaired binding in ATG16L1-knockout cells Supp. We then expressed mutant forms of LC3, which are defective for p62 binding 17 Our results showed that the average size and average number of LC3-positive structures in ATG9- and ATG16L1-knockout cells expressing pbinding defective mutant s was significantly decreased, compared to wildtype GFP-LC3 construct overexpression Supp.

We then tested whether increased p62 levels were sufficient to cause the formation of prominent LC3-positive structures in autophagy-deficient cells by overexpressing a GFP-tagged version of p62 in ATG16L1 wildtype and knockout cells.

The number and area of the LC3-positive structures increased remarkably upon p62 overexpression in the knockout but not in wildtype cells Fig.

Identification of lysosomes by fluorescence microcopy. Intracellular cathepsin K activity is detected in THP-1 cells using Magic Red Cathepsin K Kit.

Fluorophore-conjugated cathepsin substrates can be used to identify lysosomes in living cells by reporting the presence of cathepsin B, K, and L protease activity.

These cell-permeable, nontoxic reagents are added to cells and cleaved in the presence of cathepsin to yield a fluorescent product Figure 4.

When combined with nuclear dyes such as Hoechst and lysosome and organelle markers such as acridine orange, the level of autophagy can be assessed. These assays are compatible with fluorescence microscopy as well as readout using a microplate reader and can be used in conjunction with markers for the autophagosome to track autophagosome to autolysosome maturation.

Because autophagy is a dynamic process it is wise to assess autophagic flux rather than quantify autophagosome numbers alone. Autophagic flux can be measured using a variety of assays.

LC3-II turnover can be estimated by western blot by comparing LC3-II generation and turnover under different conditions or in different samples. Autophagosome to autolysosome maturation can be quantified by taking advantage of the fact that GFP, but not RFP, is quenched in the acidic lysosome environment.

Using RFP-GFP-LC3 fusions, autophagosomes appear yellow whereas autolysosomes appear red due to quenching of GFP fluorescence. Various vendors also offer tracer dyes and fluorogenic protease substrates that allow selective labeling of autophagosomes.

Finally, a highly quantitative way to measure autophagic flux is through isotopic labeling of long-lived proteins. This allows tracking of autophagy induction as a function of isotope label release upon protein degradation.

When investigating autophagy it is important to consider that there is significant crosstalk between autophagy and apoptosis; cathepsins and Beclin-1, for example, have also been implicated in mediating apoptosis.

It is therefore advisable to use multiple markers when assessing autophagy to avoid erroneous conclusions. Part four of this series will describe this crosstalk in greater detail. Table 1.

The LC3 protein is first cleaved by Atg4 at its carboxy terminus immediately after synthesis to produce LC3-I, which is localized in the cytoplasm. During autophagy, LC3-I is modified and processed by a ubiquitin-like system including Atg7 and Atg3 to produce LC3-II with a molecular weight of 14 kD and localized to autophagosomes.
