Figure Lengend Snippet: AKT-mTOR signaling links compression to autophagy in PDLCs. Compression is transmitted through AKT-mTOR signaling. Modulation of this pathway by the AKT activator SC79 and the mTOR pathway modulator 3BDO alters autophagy-related gene expression. Changes in Beclin1, P62, ATG7, ATG5 and LC3-II reflect the formation of autolysosomes and the overall level of autophagic activity in periodontal ligament cells under compression. The light red arrows indicate the increase in the levels of AKT and mTOR.

(B) Conventional EM of U2OS cells starved for 2.5 h in the presence of BafA1 showing an accumulation of different types of autophagic compartments. Autophagosomes (AP) are recognized by their double-membrane that encapsulates part of the cytoplasm with the same density as the surrounding cytoplasm and containing multiple membrane structures. Autolysosomes (AL) are vacuoles lined by a single membrane. Their lumen is heterogenous in content (membranes, vesicles, amorphous material) and electron density (from light to dense). Both AP and AL contain recognizable endoplasmic reticulum (ER) cisternae (arrows). Asterisks indicate autophagic content. (C-E) IF of semi-thin cryosections of control and starved, BafA1-treated U2OS cells, fixed either with 4% PFA ON (PFA) or 2% PFA+0.2% GA for 2 h (PFA+GA) and labeled with Cosmo Bio anti-LC3B (1:10) and Alexa Fluor 488-conjugated goat anti-mouse IgG (1:300).
