PNN and breast cancer: AATBC promotes metastasis in nasopharyngeal carcinoma via the miR-1237-3p–PNN–ZEB1 axis [104], and cervical cancer progression through miR-1245b-5p sponging [76] (It facilitates breast cancer migration via YBX1 and the YAP1/Hippo pathway [77], and drives prostate cancer cell proliferation through the miR-1245b-5p/CASK axis [75].
