Researchintothetopicofautophagystartedinthelate1950s.Atthattime,
and for the following several decades, there were few methods available
for studying this process. The initial methodology relied primarily on
electron microscopy, sometimes coupled with subcellular fractionation,
and electron microscopy remains one of the principal methods of analysis.
Additionaltechniqueswereeventuallyadded,whichincludedsequestration
andproteindegradationassays,andallofthesearedescribedinthisvolume
of Methods in Enzymology. Overall, however, the methods for examining
autophagy in mammalian cells have been relatively limited.
In the 1990s, the autophagy-related (ATG) genes were identified in
variousfungi,whichinpartopenedanewera,allowinganunderstandingof
the molecular mechanism of autophagy. In addition, the identification of
homologuestothefungalgenesinhighereukaryotesprovidedevidencefor
theroleofautophagyinagrowingnumberofprocesses,inpathophysiology
and also in development.
Although there is tremendous conservation among the autophagy-
relatedgenesacrossspecies,therelativedifficultyofusingmoleculargenetic
approaches in mammalian cell culture and, in some cases, the need to
monitor autophagy in intact organisms or tissue samples, has limited the
development of techniques for assessing autophagy in mammalian systems.
By far, the most versatile methodology among the molecular approaches
reliesondetectionoftheAtg8homologuemicrotubule-associatedprotein1
lightchain3,orLC3.Theprimaryreasonsfortheutilityofthisproteinare
that it is often upregulated following autophagy induction, it undergoes
posttranslationalmodificationsthatcanbeusedtomonitorcertainaspectsof
autophagy,anditispresentlytheonlyAtgproteinthatisreliablyassociated
with the completed autophagosome membrane. The LC3 protein can be
followed by western blot, fluorescence and immunoelectron microscopy.
Accordingly,manyofthechaptersinthisvolumedescribedifferentwaysto
use LC3 for following autophagy, and one of the main benefits of these
chapters is that they describe specific variations that are applicable to
particular systems and/or questions.
DespitetheoverallrobustnessofLC3-dependentassays,theentranceof
many researchers into this field has also led to the development of new
techniques, aswell asmodifications ofearlier approaches.Accordingly,the
