Aiming to explore the biological function of MALAT1 in PCOS, we integrated two critical lncRNA databases, LncSEA (http://bio.liclab.net/LncSEA/index.php) and LncRNA2Target (http://123.59.132.21/lncrna2target/index.jsp) with PCOS related Ovarian Kaleidoscope Database (OKdb) and Knowledgebase on Polycystic Ovary Syndrome (PCOSKB) databases. Here, MALAT1 is linked to polycystic ovary syndrome.
