Further pilot experiments demonstrated that the in vitro assays are robust for ERG, ETV1, and ETV5, three of the ETS transcription factors that are overexpressed in prostate cancer.
We have investigated ETV1, ETV4, and ETV5 overexpression, with or without PTEN loss, and their association with grade group (GG), pathological stage, focality, and PSA recurrence in PrCa.
Moreover, the prostate cancer-related oncogenic E26 transformation-specific (ETS) transcription factors, ETV1, ETV4, and ETV5, were required for TAZ gene transcription in PC3 prostate cancer cells.
GeneChip Affymetrix exon 1.0 ST arrays were used for expression profiling of ERG, erythroblast transformation-specific (ETS) variant gene 1 (ETV1), ETV4 and ETV5 genes in 67 prostate cancer tissue specimens.
Likewise, chromosomal rearrangements of the ETV1, ETV4 or ETV5 gene occur in prostate tumors and are thought to be one of the major driving forces in the genesis of prostate cancer.
The proto-oncogenes ETV1, ETV4 and ETV5 encode transcription factors in the E26 transformation-specific (ETS) family, which includes the most frequently rearranged and overexpressed genes in prostate cancer.
