The La protein is cleaved by caspase‐3 during apoptosis, resulting in translocation of the NH2 terminus part of the molecule (MW 43 kDa) to the cytoplasm265 and accessibility of this part to anti‐La antibodies.266 Since the expression of the La autoantigen is selectively induced in dead or dying cancer cells after DNA‐damaging chemotherapy, imaging of this target is an interesting strategy for the detection of tumors and the evaluation of antitumor therapy.267. Here, SSB is linked to cancer.
