Curtis et al. showed that metastasizing ovarian cancer cells can mobilize glycogen following their interaction with CAFs, which was dependent on p38-MAPK activation in CAFs, leading to increased proliferation, invasion, and metastasis.59 We also found positive correlations between lncRNA H19 and the gene levels of ERK-MAPK, p38-MAPK, and JNK-MAPK. This evidence concerns the gene MAPK8 and ovarian cancer.
