Further, EBV-encoded latent membrane protein 1 and EBV-encoded RNAs were shown to promote cell proliferation by upregulating fatty acid synthase in NPC cells (Lo et al., 2018) whereas EBV-encoded latent membrane protein 2A (LMP2A) were shown to promote lipid accumulation by blocking adipose triglyceride lipase in NPC cells, resulting in an enhanced cell migration (Zheng et al., 2020). Here, FASN is linked to nasopharyngeal carcinoma.
