Regulation of neutrophil gelatinase-associated lipocalin expression by C/EBPβ in lung carcinoma cells.

Neutrophil gelatinase-associated lipocalin (NGAL), a member of the lipocalin family, has been found to be overexpressed in a variety of tumors, including lung adenocarcinomas. However, the mechanism by which NGAL expression is regulated in lung carcinoma needs further evaluation. In this study, immunohistochemistry was employed to analyze the expression of NGAL in lung carcinoma tissue samples, including lung squamous carcinomas, adenocarcinomas, adenosquamous carcinomas and bronchial alveolar cell carcinomas.

Expression of NGAL and NGALR in human embryonic, fetal and normal adult tissues.

This study investigated the distribution of neutrophil gelatinase-associated lipocalin (NGAL) and neutrophil gelatinase-associated lipocalin receptor (NGALR) in human embryonic, fetal and normal adult tissues. Tissue microarray technology was used to perform immunohistochemical examination on human embryos, fetuses at 4-22 weeks of gestation and adult tissue specimens. Results demonstrated that during the development of the nervous system, NGALR was prevalent in the neural tube and cerebrum, and NGAL was only detected in the stellate cells of the cerebrum and the Purkinje cells of the cerebellum.

Expression of ezrin in human embryonic, fetal, and normal adult tissues.

Ezrin, which cross-links the cytoskeleton and plasma membrane, was involved in a wide variety of cellular processes. Here, to investigate the distribution of ezrin, tissue microarray technology was employed to perform immunohistochemical experiments on human embryos, fetuses at 4 to 22 weeks' gestation, and adult tissue specimens. Results showed that ezrin was widely expressed in the gastrointestinal tract throughout the human developmental stages studied.

Overexpression of neutrophil gelatinase-associated lipocalin and its receptor in colorectal carcinoma: Significant correlation with cell differentiation and tumour invasion.

Neutrophil gelatinase-associated lipocalin (NGAL), a member of the lipocalin family, is related to imflammation and tumour. Recently, a specific cell-surface receptor (24p3R/NGALR) for lipocalin 24p3 was reported. However, the characteristics of NGALR expression in colorectal carcinoma (CRC) are not known.

Expression of fascin in thyroid neoplasms: a novel diagnostic marker.

Purpose: Fascin, an actin-bundling protein, is markedly upregulated in several epithelial tumors and its expression often correlates with high-grade, extensive invasion, and distant metastasis. However, reports about fascin expression in endocrine tumors remain rare. The aim of the present study was to assess the diagnostic significance of fascin in thyroid neoplasms.

Fascin expression in human embryonic, fetal, and normal adult tissue.

This study investigates the distribution of fascin in human embryonic, fetal, and normal adult tissues. Tissue microarray technology was used to perform immunohistochemical experiments on human embryos and fetuses at 4-22 weeks of gestation and adult specimens. Fascin was widely expressed in the nervous system.
