Hormonal Regulation of Translatable mRNA of Tryptophan 2, 3-Dioxygenase in Primary Cultures of Adult Rat Hepatocytes
GHK-cu is a naturally occurring copper complex that declines as we age
Crucially, FOXO4-DRI selectively induced apoptosis in senescent TM3 Leydig cells by causing nuclear exclusion of active Ser15-phospho-p53, leading to a significant increase in apoptosis rate and altering pro-apoptotic (BAX, cleaved-Caspase3 increase) and anti-apoptotic (BCL-2 decrease) protein levels
Live cells were then washed with phosphate-buffered saline 1, incubated for 30 min with 5 M JC-1 (37 C, 5% CO 2 ), washed with PBS 1, trypsinized, and recovered in a final volume of 300 L of PBS
