CYCS and cervical cancer: On this basis, we synthesized the conjugate molecule Antp-SMCC-cytochrome c from the respective compounds (cytochrome c and Antp) using the sulfo-SMCC crosslinker and determined the effects of this Antp-SMCC-cytochrome c conjugate on survival, i.e. apoptosis activation and proliferation in HeLa cervical cancer cells.
