BPTF appears to regulate tumor growth through cell self-renewal maintenance, and BPTF knockdown leads these glial tumors toward more neuronal characteristics.
Available evidence suggests that bromodomain PHD‑finger transcription factor (BPTF) plays an important role in stem cell proliferation and differentiation, as well as in progression of some tumors, but there is little data on glioma.
The expression levels of BPTF and vimentin in CRC paraffin-embedded specimens were significantly higher than the expression in NATs (P < 0.01), while the expressions of E-cadherin in tumors were obviously lower than in NATs (P < 0.01).
A discovery exome sequencing screen (n = 17), followed by a prevalence screen (n = 60), identified new genes mutated in this tumor coding for proteins involved in chromatin modification (MLL2, ASXL2 and BPTF), cell division (STAG2, SMC1A and SMC1B) and DNA repair (ATM, ERCC2 and FANCA).
