Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Here, multispectral imaging flow cytometry with an analytical feature that compares bright detail images of 3 autophagy markers and quantifies their co-localization, along with LC3 spot counting, was used to measure autophagy in an objective, quantitative, and statistically robust manner.

Here, we present the methodology for concisely assessing autophagosome marker LC3-II levels in extracellular vesicles (EVs) by immunoblotting. Analysis for LC3-II levels in EVs, autolysosome formation, and omegasome formation suggests the new role of STX6 in the release of LC3-II-positive EVs when autophagosome-lysosome fusion is inhibited.

Conversion of Units

Sometimes, there is a need to convert from one unit to another one. For instance, reading a cookbook in which quantities are expressed in units of liters or ounces may require conversion of quantities to cups. Or, when looking up directions on how to get to a location, we may be interested to know how many miles we are going to walk. In this case, we would have to convert units of feet or meters to miles. The first step in the unit conversion is to list the given units and the units required...

Phosphatidylethanolamine attachment changes LC3-I into a membrane-associated form, allowing LC3-II to localize to nascent autophagic membranes. This lipidation step connects the ATG protein-dependent conjugation system with autophagosome formation. Consequently, detecting LC3-II provides a biochemical readout linked to the development of autophagic membrane structures rather than merely measuring total cellular LC3.
LC3-II accumulation does not by itself demonstrate that more autophagosomes are being formed. Lysosomal degradation can remove LC3-II, so blocking that degradation may cause LC3-II to build up even when the underlying formation rate is unchanged. Interpreting accumulation therefore requires attention to degradation conditions and, ideally, analysis of autophagic flux.
A change in conversion indicates an altered balance in the production of membrane-associated LC3 during autophagosome formation. However, the measurement alone cannot distinguish increased formation from reduced lysosomal removal. Comparing LC3-II levels or conversion under conditions that account for lysosomal degradation gives a more informative view of autophagic activity in cells or tissues.
Autophagic flux analysis places LC3-II measurements within the complete pathway, including both autophagosome formation and lysosomal degradation. This is important because LC3-II can accumulate when degradation is blocked, potentially mimicking increased formation. Flux-based interpretation reduces that ambiguity and helps determine whether an observed change reflects altered production, impaired clearance, or both.
Two approaches supported for this analysis are immunoblotting and fluorescence microscopy. Immunoblotting can assess LC3 forms biochemically, including LC3-II levels or the conversion from LC3-I. Fluorescence microscopy provides a cellular visualization of LC3-associated signal. Using either readout in an appropriate degradation context helps relate the measurement to autophagosome formation.
LC3-II conversion is useful when researchers need to evaluate autophagosome formation in cultured cells or tissues. Measurements can be used to compare biological conditions, but the resulting signal requires careful interpretation because lysosomal degradation affects LC3-II abundance. Incorporating autophagic flux analysis makes the assay more informative for studying changes in the autophagy pathway.
