Retracted Article: High-throughput metabolomics identifies serum metabolic signatures in acute kidney injury using LC-MS combined with pattern recognition approach.

Metabolomics, as a promising and powerful approach, refers to comprehensive assessment and identification of small molecule endogenous metabolites in a biological system which is capable of further understanding the mechanisms of diseases for early diagnosis, effective treatment and prognosis. Acute kidney injury (AKI) induced by contrast is a serious complication in patients undergoing administration of iodinated contrast media. It is becoming a major health concern in clinic, however, the molecular mechanisms of contrast-induced acute kidney injury (CI-AKI) have not been well characterized.

Proteomic analysis of the stroma-related proteins in nasopharyngeal carcinoma and normal nasopharyngeal epithelial tissues.

The stroma surrounding cancer cell population is increasingly recognized as playing an important role in cancer proliferation, invasion, and metastasis. To identify the stromal proteins involved in nasopharyngeal carcinoma (NPC) carcinogenesis, differences in protein expression of the stroma from NPC and normal nasopharyngeal epithelium tissues (NNET) were assessed using a comparative proteomic approach combined with laser capture microdissection (LCM). LCM was performed to purify stromal cells from NPC and NNET, respectively.

Identificating 14-3-3 sigma as a lymph node metastasis-related protein in human lung squamous carcinoma.

In this study, we aim to screen metastasis-related proteins in human lung squamous carcinoma (LSC) using laser capture microdissection and a proteomic approach. Twenty two differential proteins were identified from pooled microdissected primary LSC and matched lymph node (LN) metastatic tissues. Expression of the differential protein 14-3-3 sigma was determined by Western blotting and immunohistochemistry.

Quantitative proteomic analysis of differential proteins in the stroma of nasopharyngeal carcinoma and normal nasopharyngeal epithelial tissue.

The importance of stromal cells and the factors that they expressed during cancer initiation and progression have been highlighted by recent literature. To identify the stromal proteins involved in nasopharyngeal carcinoma (NPC) carcinogenesis, we assessed differences in protein expression of the stroma from NPC and normal nasopharyngeal epithelium tissues (NNET) using a quantitative proteomic approach combined with laser capture microdissection (LCM). LCM was performed to purify stromal cells from the NPC and NNET, respectively.
