NDRG1 and Miyoshi myopathy: To investigate how KSHV utilizes cellular factors to maintain viral persistence during latency, we compared primary rat embryonic metanephric mesenchymal precursor cells (MM cells) and KSHV-immortalized MM cells (KMM cells) [32] and identified a host protein, named N-Myc downstream regulated gene 1 (NDRG1), that was distinctly upregulated in KMM cells.
