For instance, miR-144-3p, miR-155, miR-205-5p, and miR-144, oncogenic miRNAs that are overexpressed in some cancers, induce NPC cell invasion, migration, and proliferation but restrain apoptosis directly by targeting the PTEN tumour suppressor, leading to upregulation of PI3K/AKT signalling [96, 124–126]. Here, PIK3CA is linked to nasopharyngeal carcinoma.
