title: THSD7A expression in human cancer.
abstract: We recently described a case of a Thrombospondin Type-1 Domain containing 7A (THSD7A) associated membranous nephropathy in a female patient who was synchronously suffering from a THSD7A-positive malignancy. We here investigated the role of THSD7A as a new potential tumor antigen by evaluating over 20 000 tissue spots in more than 70 different tumor entities by immunohistochemistry using tissue microarrays. THSD7A expression was highly variable in different neoplasias with differing staining patterns. Both gain and loss of THSD7A expression compared to expression status in non-tumor tissue were linked to tumor-specific markers in the different tumor entities and were of prognostic value. The potential role of THSD7A in tumor development and therapy needs further investigation.
