Abnormal transcription of miR-1343-3p can affect the growth and migration of tumors.42–44 miR-1343-3p in lung cancer is inhibited by lncRNA 02323, resulting in up-regulated expression of TGFBR1 and promoting interstitial transformation and cancer cell metastasis.43,44 The expression and activation of gastric cancer carcinogen TEAD4 are also silenced by miR-1343-3p.45 However, the regulatory relationship between miR-1343-3p, MAP3K6 and MMP24 in gastric cancer cells has not been reported. Here, MAP3K6 is linked to cancer.
