In addition, the analysis of upstream miRNAs showed that FOXF1 adjacent non‑coding developmental regulatory RNA (FENDRR) had common upstream miRNAs, including miR‑18b‑5p, with another 119 differentially expressed genes, and that FENDRR was co‑expressed with adenomatosis polyposis coli downregulated 1 (APCDD1) and v‑kit Hardy‑Zuckerman 4 feline sarcoma viral oncogene homolog (KIT).
