To determine whether TBB inhibition preferentially triggers apoptosis of senescent cells, Zmpste24 / MEFs treated with TBB were stained for C 12 FDG to label senescent cells, then stained for Annexin V, an early apoptosis marker, and 7-aminoactinomycin D (7-AAD), a membrane impermeable dye that is generally excluded from viable cells as a later apoptosis marker, and finally analyzed with flow cytometry

Enzymes that could be involved are: -glutamylcysteine synthetase, glutathione synthetase, glutathione peroxidase, glutathione disulfide reductase, glutathione-S-transferase, GSH or GSSG transport protein, cysteine or cystine transport proteins, glycine transport proteins, glutamate transport proteins, glucose-6-phosphate dehydrogenase, and many others
The result is visible streaks where the skins supportive structure has weakened, similar to a stretched fabric that loses its original shape
