A recent report indicated that the long noncoding RNA (lncRNA) protein disulfide isomerase family A pseudogene 1 (PDIA3P), which is highly expressed in MM, interacts with MYC and enhances the transactivation of glucose-6-phosphate dehydrogenase (G6PD) promoter, upregulating this rate-limiting PPP enzyme [97]. The gene discussed is G6PD; the disease is Miyoshi myopathy.
