PLCD1 and non-small cell lung carcinoma: Based on studies, the PI3K/Akt signaling pathway in NSCLC cells could be stimulated by circ_0000376, circRNA_100876, circPVT1, circ_0016760, circ_0102231, hsa_circ_0018818 and restrained by circLIFR and circ-PLCD1 ceRNA networks that are discussed below [[165], [166], [167], [168], [169], [170], [171], [172]].
