General description

Napsin is a pepsin-like aspartic proteinase in the A1 clan of the AA clade ofproteinases. Napsin A is involved in processing propeptide pulmonary surfactant protein B(proSP-B) in the lung. In normal, benign tissue, Napsin A has expressed in type II pneumocytesof the lung and proximal tubules of the kidney. Napsin A is a useful marker for lungadenocarcinoma.

Surfactant protein B (SP-B) is a critical component of pulmonary surfactant, and a deficiency of active SP-B results in fatal respiratory failure. SP-B is synthesized by type-II pneumocytes as a 42-kDa propeptide (proSP-B), which is posttranslationally processed to an 8-kDa

The availability of targeted therapies has created a need for precise subtyping of non-small cell lung carcinomas (NSCLCs). The aim of this study was to assess the utility of immunohistochemical markers in subtyping poorly differentiated NSCLC and to compare the

The purpose of this study was to test napsin A as a diagnostic marker of metastatic lung adenocarcinoma in pleural effusions, and to compare its performance with TTF-1. Napsin A and TTF-1 reactivities were determined immunohistochemically on formalin-fixed paraffin embedded

Primary pulmonary adenocarcinomas with enteric differentiation (PAED) are mainly composed of tall-columnar cells that show similarity to intestinal epithelia and colorectal carcinomas. In this study, we analyzed the immunostaining profiles of 7 PAEDs in comparison with 14 metastatic colorectal carcinomas
