LY75 (Lymphocyte Antigen 75) is a Protein Coding gene. It is broadly expressed in the lymph node, appendix, and other tissues. LY75 knockdown in SKOV3 cells resulted in predominant upregulation of functional pathways implicated in cell proliferation and metabolism, while pathways associated with cell signaling and adhesion, complement activation, and immune response were mostly suppressed. Moreover, LY75 suppression had an opposite effect on EOC cell lines with the epithelial phenotype (A2780s and OV2008), by directing epithelial-to-mesenchymal transition (EMT) associated with reduced capacity for in vivo EOC cell colonization, as similar/identical signaling pathways were reversely regulated, when compared to mesenchymal LY75 knockdown EOC cells. Diseases associated with LY75 include Pneumonic Plague and Adenoiditis.
