    ..Such functional interaction between PIN1 and survivin may therefore play an important role in hepatocarcinogenesis and chemoresistance. ..

    ..These results provide a rationale for the use of small-molecule inhibitors of stress-responsive protein kinases and Pin1 as a potential therapeutic strategy for HD treatment. ..
