Transcription Repressor Activity of Spleen Tyrosine Kinase Mediates Breast Tumor Suppression

Mediates Breast Tumor Suppression Transcription Repressor Activity of Spleen Tyrosine Kinase

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 ...

Spleen Tyrosine Kinase Inhibition Modulates p53 Activity

Spleen tyrosine kinase (SYK) is a cytoplasmic enzyme that promotes survival and proliferation of B cells. SYK inhibition has shown promising results in the treatment of arthritis and chronic lymphocytic leukemia (CLL). However, in other context, it has been shown that SYK overexpression in epithelial cancer cells induced senescence in p53-dependent mechanism, which underscored its antineoplasti...
