PIK3CA and cancer: They found DANCR inhibited the expression of NPTN‐IT1 by binding with EZH2 and HDAC3.76SNHG14 suppressed the inhibition of MIR‐145 on SOX9, and activated the PIK3CA/AKT/MTOR signaling pathway to accelerate cell proliferation and invasion.77SNHG15 was expressed at a higher level in cancer tissues, with expression increased by over 1.5‐fold compared to the normal tissues.
