Our findings highlight a novel mechanism, in which circPSAP functions as a miR-331-3p sponge to impact MM cell proliferation, apoptosis and BTZ sensitivity by regulating HDAC4 expression.
Circular RNA circPSAP functions as an efficient miR-331-3p sponge to regulate proliferation, apoptosis and bortezomib sensitivity of human multiple myeloma cells by upregulating HDAC4.
