In the current study, we demonstrated that TMEM14A was overexpressed in ovarian cancer tissues by analysing independent dataset downloaded from TCGA and our own real-time PCR results on 30 pairs of ovarian cancer and normal tissues (Figure 1); in addition, the influence of TMEM14A on the biological behaviour of ovarian cancer cells was investigated (Figure 3). Here, TMEM14A is linked to ovarian cancer.
