Extrinsic apoptotic pathways are activated by interactions between cell surface exposed death-inducing ligands such as FAS ligands (FASL) and tumor necrosis factor (TNF), and their cognate receptors Fas cell surface death receptor (FAS) and TNF receptor (TNFR) [110, 111]
It's the gold standard for preserving the integrity of sensitive biological compounds

In these cells, the transcription factor FOXO4 is highly upregulated and physically sequesters the tumor suppressor p53 in nuclear foci, preventing p53 from triggering apoptosis
Choline is also the precursor of the neurotransmitter ACh, whose synthesis is catalyzed by choline acetyltransferase (ChAT), transferring an acetyl group from acetyl-coenzyme A to choline, resulting in ACh and coenzyme A production ( Figure 2 )
