    1. These data indicated that napsin A expression may inhibit TGFbetalinduced EMT and was negatively associated with EMTmediated erlotinib resistance, suggesting that napsin A expression may improve the sensitivity of lung cancer cells to EGFRTKI through the inhibition of EMT. PMID: 29845258
    2. Although napsin A is infrequently expressed in endometrial carcinomas, positive results of napsin A immunostaining in endometrial neoplasms might support the diagnosis of clear cell carcinoma when the pathologic differential diagnosis includes other histologic subtypes PMID: 26945446
    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
    4. To the best of our knowledge, expression of monoclonal Napsin A in lymphomas has never been reported. ALK-DLBCL should be considered in the differential diagnosis when evaluating a Napsin A-positive tumor of poorly differentiated morphology and of unknown primary PMID: 26808134
    5. It is important for pathologists to be aware that breast carcinomas with apocrine features can express napsin A. PMID: 26842346
    6. High Napsin A expression is associated with adenocarcinoma in non-small cell lung carcinoma. PMID: 27412420
    7. Napsin-A, and Desmocollin-3 were sensitive and specific markers for the diagnosis of AC and SCC, respectively. Both markers allowed classification of 54/60 cases into either AC or SCC. PMID: 26710975
    8. napsin A is aberrantly expressed in a subset of lymphomas PMID: 26400099
    9. CK7, TTF-1 and napsin A are predominantly expressed in primary lung adenocarcinoma patients, with CDX-2 being inconsistently expressed. PMID: 26469326
    10. Combining HNF-1beta and napsin A may distinguish clear cell carcinoma from high-grade serous carcinoma, endometrioid adenocarcinoma and metastatic Krukenberg tumors. PMID: 26339401
    11. napsin A is another sensitive and specific marker for distinguishing ovarian clear cell tumors (especially adenocarcinomas) from other ovarian tumors PMID: 24721826
    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

    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

    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

    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
    35. Although TTF-1 had a higher sensitivity, napsin-A was useful as a surrogate marker when encountering a poorly differentiated lung adenocarcinoma. PMID: 20830690
