To gain further insights into the functional impact of LKB1 on ovarian cancer progression, we analyzed the mRNA expression levels of LKB1 and its major downstream 13 kinase in ovarian tumor tissues compared with normal tissues using ovarian cancer datasets from TCGA and GTEx projects through GEPIA (Tang et al., 2017) (Figure 4B). The gene discussed is STK11; the disease is ovarian carcinoma.
