Additionally, enhanced lnc‐PCAT1 promotes plasma cell proliferation and inhibits apoptosis by downregulating microRNA‐129 (miR‐129) and further regulating mitogen‐activated protein kinase kinase kinase 7/nuclear factor‐kappaB (MAP3K7/NF‐κB) pathways in MM.12 This evidence concerns the gene NFKB1 and Miyoshi myopathy.
