The detection and analysis of differential regulatory communities in lung cancer.

The tumorgenesis process of lung cancer involves the regulatory dysfunctions of multiple pathways. Although many signaling pathways have been identified to be associated with lung cancer, there are little quantitative models of how inactions between genes change during the process from normal to cancer. These changes belong to different dynamic co-expressions patterns.

Physcion 8-O-β-Glucopyranoside Exerts Anti-Tumor Activity Against Non-Small Cell Lung Cancer by Targeting PPARγ.

Lung cancer is one of the most common causes of cancer related mortality. The present study is designed to investigate whether a naturally occurring anthraquinone compound, physcion 8-O-β-glucopyranoside (PG) could exert anti-cancer activity against non-small cell lung cancer (NSCLC). Cell viability was determined by Cell Counting Kit-8 (CCK-8) assay.

Insulin-like growth factor binding protein-4 inhibits cell growth, migration and invasion, and downregulates COX-2 expression in A549 lung cancer cells.

Insulin-like growth factor binding protein 4 (IGFBP-4) and cyclooxygenase2 (COX-2) are associated with tumor inflammatory microenvironment which is involved in the progression of tumor. However, it is unclear that the roles of IGFBP-4 in lung cancer and the effects of IGFBP-4 on COX-2 expression. In this study, we showed that IGFBP-4 could decrease COX-2 production in lung cancer A549 cells.

[Comparative studies on genetic resource of characteristics of Alisma].

Based on the introduction and cultivation of Alisma germplasm which were from Fujian, Jiangxi and Sichuan provinces, the biological characteristics, morphological characteristics and quality were observed and studied. After three-year continuous experiment and monographic study, there were remarkable difference in the biological characteristics, morphological characteristics and product quality of Fujian Alisma, Sichuan Alisma and Jiangxi Alisma. Fujian Alisma and Jiangxi Alisma were the same plant species of A.
