DOCK7 and neoplasm: Other examples of cancer-related genes with differentially spliced microexons include SPTAN1 (S13 Fig), a ubiquitously expressed cytoskeletal protein which has recently been shown to affect tumor growth by enhancing cell proliferation and migration [51]; DOCK7 (S14 Fig), which regulates the RAGE-Cdc42 pathway that promotes cancer progression [52] and glioblastoma cell invasion [53]; and PSAP (S15 Fig), which has been implicated in the tumorigenesis of glioblastoma [54], prostate [55,56], and breast cancer [57].
