PVT1 and nasopharyngeal carcinoma: In nasopharyngeal carcinoma, hsa-miR-1207 has been shown to be inhibited by non-coding RNA Pvt1 or long non-coding RNA 319, which may act as a sponge to miRNAs, inducing cellular proliferation via PI3K/AKT (Xiao et al., 2018), or carcinogenesis via KLF12 signaling pathways (Nunziato et al., 2019), respectively.
