Compared with the PARP-1 expression in paired adjacent normal tissue, enriched expression of PARP-1 was also detected in STS tumor tissues of three patients, including high grade spindle cell sarcoma, pleomorphic rhabdomyosarcoma, and high grade pleomorphic undifferentiated sarcoma (Figure 4D). The gene discussed is PARP1; the disease is pleomorphic rhabdomyosarcoma.
