  • Our previous report showed that FO inhibits HCC cell invasion via AKT-, mitogen-activated protein kinase- (MAPK-), and EMT-related signals [ 7 ]. (hindawi.com)
  • With the presence of both signals, the AND gate outputs a repressor protein and then changes the state of the bistable switch, which acts as a memory module. (igem.org)
  • In this way, our E. coli cells can convert the information about the concurrence of the two signals into its memory. (igem.org)
