Most wild type Tetrahymena have a macronucleus and a micronucleus. The micronucleus, seen here, is essentially nonfunctional during interphase. Its function is to replicate and pass a complete copy of...

Saccharomyces cerevisiae (WT BY4741-MATa his3Δ1 leu2Δ0 met15Δ0 ura3Δ0), transformed with EGFP-Atg8p, undergoing chronological aging on small synthetic 2% glucose media (SMD) without supplementatio...

Human colon carcinoma HCT 116 cells were transfected with an siRNA specific for SIRT1 and then retransfected with a GFP-LC3-encoding plasmid, cultured in complete medium for 24 h and treated with 100 ...

Human colon carcinoma HCT 116 cells were transfected with an irrelevant siRNA and then retransfected with a GFP-LC3-encoding plasmid, cultured in complete medium for 24 h and treated with 100 µM sper...

Human colon carcinoma HCT 116 cells were transfected with an irrelevant siRNA and then retransfected with a GFP-LC3-encoding plasmid, cultured in complete medium for 24 h and treated with 100 µM resv...

Image indicative of 24 h autophagic activity of human colon carcinoma HCT 116 cell co-transfected with a RFP-LC3-encoding plasmid and an empty vector (pcDNA3) as a control. Confocal fluorescent images...

Human colon carcinoma HCT 116 cells were transfected with an siRNA specific for SIRT1 and then retransfected with a GFP-LC3-encoding plasmid, cultured in complete medium for 24 h and treated with 100 ...

Transgenic C57BL/6 mice expressing GFP-LC3 fusion protein, uninjected as control for injection with Resveratrol and/or spermidine. To avoid postmortem autophagy induction, dead mice were immediately p...
