Transcription Repressor Activity of Spleen Tyrosine Kinase Mediates Breast Tumor Suppression

Abstract excerpt

Spleen tyrosine kinase (SYK) is a candidate tumor suppressor gene in breast. Loss of SYK expression in breast tumors as a result of DNA hypermethylation promotes tumor cell proliferation and invasion and predicts shorter survival of breast cancer patients. We previously reported that, in addition to its well-known cytoplasmic localization, the full-length Syk is also present in the nucleus and that Syk nuclear...
