DEPDC5 and neoplasm: The events that showed the most increased PSI in the tumor were those in TPM1 (member of the tropomyosin family), COL5A1 (encodes alpha chain for fibrillar collagen), DEPDC5 (inhibits mTORC1 pathway), PIFO (involved in cilia formation), SREK1 (SR splicing protein) and SNRPD1 (part of the spliceosome).
