The interactions of 8 proteins (ADCY3, ADCY6, ADCY7, IGF1R, MAP2K1, MAPK1, MAPK3, and PRKACA) encoded by the genes regulated by selected miRNAs involved in oocyte meiosis, progesterone-dependent oocyte maturation and the cancer pathways and 6 exosomal proteins (CD9, CD24, CD63, CD81, CD151, and TSPAN8) were analyzed using the STRING database (string-db.org). The gene discussed is PRKACA; the disease is cancer.
