7. A panel of three tumor markers CYFRA 21.1, HE4 and ProGRP may play a role for discriminating LC from benign lung disease and subtyping as SCLC. PMID: 29729229
8. Serum Smac expression level was significantly lower in the EAOC group than in the control group and benign ovarian tumor group (P< 0.05), while HE4 and CA125 expression levels were significantly higher in the EAOC group than the other two groups. PMID: 29226858
9. This study demonstrated that altered expression of HE4 may involve in tumorigenesis in the uterine cervix. Our findings also suggested the presence of a correlation between HE4 expression and the invasive potential of uterine tumors. Therefore it may be thought that the tissue expression of HE4 can be used to differentiate high grade intraepithelial tumors from carcinomas. PMID: 28326512
10. Use of HE4 instead of CA125 did not significantly improve diagnostic performance of risk of malignancy indices 1-4 in patients with an adnexal mass PMID: 29238719

28. Serum HE4 levels were significantly elevated in children and adults with cystic fibrosis (CF) compared to controls. Abnormal but lower HE4 concentrations were found in cases of severe bronchitis, asthma, pneumonia, and bronchiectasis. HE4 mRNA levels were significantly upregulated in CF vs. non-CF airway biopsy specimens. PMID: 27105680
29. Human epididymis protein 4 induces chemoresistance against anti-cancer drugs and activates the AKT and Erk pathways to enhance tumor survival.
