EIF2AK2 and nasopharyngeal carcinoma: With the advancements in designing of structural and in vivo stability, RNA‐target small molecules have been developed to specifically target non‐coding RNA and effectively disrupt its interaction with proteins.[59] Here, we identified circWDR37 as a key regulator of NPC metastasis and senescence by interacting with PKR protein to promote its dimerization and phosphorylation.
