It inhibits cell growth and tumorigenicity by directly repressing the tumour suppressor large tumour suppressor kinase 2 (LATS2) and protein phosphatase 2 regulatory subunit B α (PPP2R2A), establishing a novel regulatory network in lung cancer via the miR-31-LATS2-PPP2R2A pathway [59]. The gene discussed is PPP2R2A; the disease is lung carcinoma.
