More importantly, SIK2 expression was also positively correlated with MYLK‐pS343 expression in ovarian cancer tissues (r = 0.71, P < 0.0001; Fig. 6F), suggesting that tumours with high SIK2 expression were likely to have high MYLK‐pS343 expression. The gene discussed is SIK2; the disease is ovarian carcinoma.
