Lentiviral shRNA screen of human kinases identifies PLK1 as a potential therapeutic target for osteosarcoma.

abstract：:B7-homolog 4 (B7-H4), a recently identified homolog of B7.1/2 (CD80/86), has been described to exert co-stimulatory and immune regulatory functions. We investigated the expression and the functional activity of B7-H4 in lung cancer in vitro and in vivo. Although a lung cancer cell line constitutively expressed B7-H4 m...
