Pyruvate dehydrogenase protein X component (PDHX) has been identified by Chen et al. as a direct target of miR-26a in colorectal cancer (CRC) cells, and miR-26a is known to modulate PDHX expression by directly targeting the 3′UTR of PDHX [170]. The gene discussed is PDHX; the disease is colorectal carcinoma.
