5 mirns regulate s ig. S: Validation of mirn expression changes in s and induced s identified in the mirn array., RN was extracted from s isolated from the omental metastasis of patients with high grade serous OvCa (ex vivo) and matching adjacent s or from s and induced s derived from a two day co-culture of s with Hey8 cells (in vitro). he indicated mirns were quantified by quantitative real time PCR. Changes for corresponding pairs of fibroblasts for each individual patient are shown. Significance was determined using one-tailed paired t-test., In situ hybridization of human ovarian cancer omental metastasis and adjacent normal omentum for mir-4 (top) and mir-55 (bottom). Scale bar = µm. Stippled lines indicate the borders between areas of adipocytes () and fibroblasts () (rows and ) or tumor tissue () and fibroblasts () (rows and 4). Page 5 of

Overexpression of mir-4 (4), mirn- (), or inhibition of mir-55 (LN anti-mir-55) in s inhibits migration (), their ability to enhance Hey8 cell invasion (), and anchorage independent growth tested by colony formation (C). Negative controls () are indicated. D-, Reprogramming of s to s. Inhibition of mir-4 or mir-, or overexpression of mir-55 (55) in increases their migration (D), their ability to enhance Hey8 cell invasion (E), and anchorage independent growth ().
