Nasopharyngeal carcinoma (NPC) is a common cancer among southern Chinese. The profile of gene expression in NPC cells is largely unknown. In this study, we have examined differential gene expression in non-malignant and malignant nasopharyngeal epithelial (NPE) cells using a cDNA array hybridization method. A total of 42 genes were identified to be expressed in either non-malignant and malignant NPE cells or both. Thirteen of these genes were overexpressed in malignant NPE cells. These includes nuclear factor (NF90), FOS-related antigen 1 (FRA- 1), cytoplasmic dynein light chain (HDLC1), replication factor C (RFC1), nucleoside diphosphate kinase B, UV excision repair protein (RAD23A), insulin-like growth factor receptor II, transcription initiation factor TFIID subunit (TAFII31), growth factor receptor-bound protein 2 (GRB2), UV excision repair protein (RAD23B), glutathione peroxidase, Y box binding protein 1 and heat shock protein 86. In contrast, expression of nine genes was suppressed in malignant NPE cells. These includes calgranulin A, calgranulin B, neutrophil activating protein (ENA-78), heat shock protein 27, integrin beta-1, integrin beta-4, cyclin-dependent kinase inhibitor 1A (p21), interleukin-8 and tyrosine protein kinase receptor (RET). Differential expression of calgranulin A, calgraunlin B, ENA-78, FRA-1 and NF90 in non-malignant and malignant nasopharyngeal epithelial cells was confirmed by RT-PCR analysis.

The molecular mechanisms regulating uterine relaxation and contraction during pregnancy are poorly understood. In the present study, we used for the first time a functional genomics approach applying gene array technology to identify novel candidate genes involved in the regulation of uterine quiescence and contractility during pregnancy. The purpose of this approach was to obtain a molecular snapshot of the expression profile of gene transcripts as a function of the time dependent process regulating myometrial quiescence. Using this approach, we found several genes whose expression in human myometrium was altered with the onset of labour. For example, the expression of insulin-like growth factor (IGF)-II, calgranulin A and B, and G-protein coupled receptor were decreased while the expression of IGF-binding proteins, Ca(2+)/CaM binding protein kinase C substrate, and angiotensin converting enzyme were increased in the labouring, compared with non-labouring, pregnant myometrium. The differentially-expressed genes include several genes whose roles in myometrial quiescence are yet to be understood, although they have been reported to regulate vascular smooth muscle tone. Our findings illustrate the advantage of a functional genomics approach over a single gene analysis in identifying a large number of novel and potentially important genes mediating uterine smooth muscle contractile activity.

Various biomarkers of acute kidney injury (AKI) have been discovered and characterized in the recent past. These molecules can be detected in urine or blood and signify structural damage to the kidney. Clinically, they are proposed as adjunct diagnostics to serum creatinine and urinary output to improve the early detection, differential diagnosis and prognostic assessment of AKI. The most obvious requirements for a biomarker include its reflection of the underlying pathophysiology of the disease. Hence, a biomarker of AKI should derive from the injured kidney and reflect a molecular process intimately connected with tissue injury. Here, we provide an overview of the basic pathophysiology, the cellular sources and the clinical performance of the most important currently proposed biomarkers of AKI: neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), liver-type fatty acid-binding protein (L-FABP), interleukin-18 (IL-18), insulin-like growth factor-binding protein 7 (IGFBP7), tissue inhibitor of metalloproteinase 2 (TIMP-2) and calprotectin (S100A8/9). We also acknowledge each biomarker's advantages and disadvantages as well as important knowledge gaps and perspectives for future studies.
