However, many Yin genes reported here were found in previous studies that relate lung cancer or other tissue type cancer development such as GRIN2D [28], GAST [29], AMH [30], TCF3 [31], EXOSC2 [32], GRM1 [33], CDT1 [34], RecQL4 [35], CSTF2 [36], FCGR2B [37], RNASEH2A [38], CDC6 [39], CACYBP [40], BIRC5 [41], CDC25 [42], NRAS [43], EN2 [44], and MIF [45]. Here, EN2 is linked to lung cancer.
