Number of included studies that examined genes or pathways and their associated functions in the treatment of ovarian cancer: The most extensively studied gene and its associated pathway was miRNA (n = 11), followed by various EphA2 (n = 7), different MAPK (n = 6), then interleukins (n = 5) and hTERT/E1A (n = 5). miRNA, micro-ribonucleic acid; EphA2, ephrin type-A receptor 2; MAPK, mitogen-activated protein kinase; hTERT/E1A, human-telomerase reverse transcriptase/E1A; MDR1, multidrug resistance mutation 1
