In human muscle precursor cells grown in the lab, a compound called oleuropein aglycone causes a short-lived rise and fall in a specific cellular energy sensor (AMPK) within hours, while other cellular cleanup processes stay active, suggesting the response changes over time in a complex pattern.

In human muscle precursor cells grown in the lab, a compound called oleuropein aglycone increases markers of autophagy—cellular cleanup processes—to the same extent as rapamycin, a known trigger of autophagy.

Oleuropein aglycone, a compound found in olives, triggers a sequence of molecular events in human nerve cancer cells and mouse brain tissue that leads to the formation of cellular structures involved in recycling damaged components. This process is associated with changes in calcium levels and specific protein modifications.

In human neuroblastoma cells, a compound called oleuropein aglycone at a concentration of 50 μM triggers two distinct increases in calcium levels inside the cell, originating from the endoplasmic reticulum, and these calcium changes are necessary to activate AMPK and start the process of autophagy.

Oleuropein aglycone, a compound found in olive plants, triggers a cellular cleanup process called autophagy in human cancer cells and mouse brain tissue by altering specific signaling molecules that regulate this process.

In human muscle cells grown in the lab, a compound called oleuropein aglycone at a concentration of 25 micromolar, applied for 24 hours, increases the activity of genes involved in antioxidant defense and raises a molecular marker associated with autophagy during oxidative stress.
