Inhibin β A (INHBA) is a member of the transforming growth factor β (TGF-β) superfamily. INHBA expression is associated with several types of human cancers; however, its significance in colorectal cancer (CRC) is not fully understood. INHBA expression was studied in 126 primary CRC samples and 4 CRC cell lines. Cell growth was assessed after inhibition of INHBA e xpression o r a fter e xogenous overexpression of INHBA in CRC tissues. INHBA expression was significantly higher in CRC tissues when compared to that in the corresponding normal tissues (P<0.001). Patients in the high expression group showed a poorer overall survival rate when compared to those in the low expression group (P<0.001); the present study did not evaluate for an independent prognostic factor but showed the significance of lymph node metastasis as an independent prognostic factor. The present study suggests that INHBA is useful as a predictive marker for prognosis in CRC patients.
