COL1A2 and cancer: Interestingly, these two modules contain three common mRNAs (EMILIN1, COL1A2, ENC1) and one of them (COL1A2) is related to cancer, suggesting that these modules (e.g. modules 15 and 17, modules 31 and 32 in OV) with many overlaps of mRNAs are more likely to have similar biological functions.
