For example, one study showed that expression of a GAGE family member (GAGE‐7C) confers significant resistance to apoptotic stimuli—acting downstream of caspase‐8 activation but upstream of PARP cleavage—to promote cell survival in the face of Fas‐mediated apoptosis as well as chemotherapeutic and radiotherapeutic treatments."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": " In addition, research has demonstrated that GAGE proteins can physically interact with nuclear envelope regulators such as Germ cell-less (GCL) and bind double‐stranded DNA in a sequence‐nonspecific manner.
