CASP6 and hereditary pheochromocytoma-paraganglioma: Knockdown of lncRNA BC088414 decreased the mRNA expression of caspase-6 (Casp6) and β2-adrenoceptor (Adrb2), which are apoptosis-related genes, thereby reducing the cell apoptosis and promoting cell proliferation in pheochromocytoma-12 (PC-12) neural cells.
