Abstract
MicroRNAs are small non-protein coding RNAs that regulate gene expression through post-transcriptional repression. Recent studies demonstrated the importance of microRNAs in the nervous system development, function and disease. Parkinson's disease is the second most prevalent neurodegenerative disease with only symptomatic treatment available. Recent success in using small RNAs as therapeutic targets hold a substantial promise for the Parkinson's disease field. Here we review recent work linking the microRNA pathway to Parkinson's disease.

Abstract
Objective: We aimed to explore the bioinformatics of endometrial carcinoma (EC) metastasis. Methods: The microarray information of 4 cases of progressive endometrial cancer (PEC) and 4 cases of non-progressive controls (NPC) were collected from the Gene Expression Omnibus Database (GEOD). The Limma package in R was performed to selected the differentially expressed genes (DEGs). Then, the hierarchical clustering of DEGs was carried out. In addition, bioinformatics analysis was carried out. Results: There were 65 DEGs identified between PEC and NPC. Those DEGs were mostly enriched in cell proliferation function, MAPK and TGF-beta signaling pathways. Furthermore, those DEGs were related to of the increased contents of IGF2 and PLAG1, and decreased contents of THBS4 and FGF20. Conclusions: There were 65 DEGs identified in endometrial cancer between progressive and non-progressive. Those DEGs were significantly related to tumor metastasis. Increased levels of IGF2 and PLAG1, and decreased levels of THBS4 and FGF20 may have a notable effect on the development of EC.
