3. it may be useful to combine NAPA and TTF-1 for increased sensitivity in lung cancer diagnostics. There is no substantial difference between monoclonal and polyclonal p40 and between different NAPA clones, whereas there is a difference between the TTF-1 clones 8G7G3/1 and SPT24 PMID: 26447895

12. Napsin A is expressed in a broad spectrum of renal neoplasms. PMID: 25889632
13. Low expression levels of NAPSA is associated with lung adenocarcinoma. PMID: 25982999
14. In diagnosis of ovarian clear cell carcinoma, Napsin A is specific but of intermediate sensitivity. PMID: 25551297
15. Napsin A is frequently expressed in ovarian and endometrial clear cell carcinomas. PMID: 25971546
16. Data indicate that polyclonal but not monoclonal napsin A antibody has a virtually universal nonspecific labeling in mucinous adenocarcinomas of various sites. PMID: 25521803
17. These data suggest that napsin A may be a useful marker for identifying metastatic adenocarcinomas of pulmonary origin PMID: 24479710
18. Our study showed that napsin A is an extremely sensitive (100%) marker of ovarian clear cell carcinomas PMID: 25389337
19. Napsin A as a marker of clear cell ovarian carcinoma. PMID: 24191930
20. PAX2 and napsin A have high specificity but low sensitivity and only have limited value in the differential diagnosis of mesotheliomas and renal cell carcinomas PMID: 23503645
21. TTF-1 is more sensitive than napsin for detection of lung sarcomatoid carcinoma, and no cases were positive for napsin but negative for TTF-1 PMID: 24331839
22. Napsin A is a sensitive and specific biomarker of the clear cell histotype in endometrial carcinomas and accordingly may have diagnostic utility in their histotyping. PMID: 24145649
23. 24 cases each of pulmonary and esophageal adenocarcinoma were stained with TTF-1, napsin A, CDX2, 34betaE12, N-cadherin, and IMP3 in an attempt to find an optimal panel for differentiation. IMP3, CDX2, and N-cadherin are superior to either TTF-1 or napsin A. PMID: 23899066
24. Napsin-A seems to be a useful marker in classifying primary pulmonary neoplasm as adenocarcinomas. PMID: 22914608
25. A minority of anaplastic and poorly differentiated micropapillary pattern thyroid carcinomas are napsin A positive. PMID: 23681073
26. Napsin B was duplicated from napsin A during the early stages of primate evolution, and the subsequent loss of napsin B function during primate evolution reflected ongoing human-specific napsin B pseudogenization PMID: 23333608
27. Mucin-producing neoplasms of the lung infrequently express napsin A, suggesting that immunohistochemical assessment of napsin A may have limited diagnostic usefulness for distinguishing primary and metastatic mucinous adenocarcinomas involving the lung. PMID: 23355200
28. investigation of expression of NAPSA (a potential diagnostic marker) in lungs/respiratory mucosa of subjects with pulmonary sclerosing hemangioma PMID: 23194051
29. a useful immunohistochemical marker for differentiation of lung squamous cell carcinoma and adenocarcinoma from other subtypes PMID: 22495379
30. absence of napsin A was an independent prognostic factor for reduced survival time in lung adenocarcinoma PMID: 22418245
31. Nap-A was more specific than thyroid transcription factor 1 for primary lung adenocarcinoma versus all tumors, excluding kidney, independent of tumor type PMID: 22288963
32. None of the 90 squamous cell carcinomas of the lung exhibited napsin A positivity in the neoplastic cells; however, strong napsin A reactivity was observed in hyperplastic type II pneumocytes and in intra-alveolar macrophages entrapped within the tumor. PMID: 22198009
33. napsin A is a useful marker that can assist in the diagnosis of both lung adenocarcinomas and renal cell carcinomas[review] PMID: 22156835
34. in combination with thyroid transcription factor-1-positive immunostaining helps in differentiating primary lung adenocarcinoma from metastatic carcinoma in the lung PMID: 21464700
