View SamplesMiR-138 has a variety of biological functions because of its capacity to act on different target genes in various cells and tissues; however, the targets of miR-138 in human non-small cell lung cancer cell line H1299 cannot be determined by bioinformatics alone. Thus, H1299 cells overexpressing miR-138 in H1299 cells were subjected to microarray analysis to analyse the differences of gene expression.

View SamplesHuman tumor cell lines are important tools in tumor biological studies, here the authors report the establishment and characterization of 7 new ccRCC stable cell lines with complete clinical data. Gene expression and methylation were profiled with microarrays between the new cells and those had a finite in vitro life span, and the results prompt that genes such as SLC34A2 and VHL play key roles in the continuous in vitro growth and development of ccRCC.

View SamplesAngiotensin II (Ang II) mediated signaling plays a key role in the development of hypertension associated target organ damages. However, the gene expression changes regulated by Ang II in the early stage of acute cerebral, cardiac, renal, vascular injury remain unclear.

View SamplesThe clinical application of doxorubicin as a broad-spectrum anti-tumor antibiotic is limited greatly by its cardiotoxicity. Various mechanisms have been studied, but little is known about whether genes or pathways relevant with energy metabolism contributes to doxorubicin-induced cardiomyopathy or not.

View SamplesNasopharyngeal carcinoma (NPC) is an epithelial malignancy with striking racial and geographic distribution differences. Furthermore, numerous genetic linkage and association studies have reported a few genes contributing to the risk of this malignancy. The identification of susceptibility genes contributing to NPC would assist in predicting individual and population risk of NPC development and would help to clarify the pathogenesis relevant to this disorder. Argonaute 2 (AGO2), a central component of RNA-induced silencing complex, plays critical roles in cancer. We examined whether the single nucleotide polymorphisms (SNPs) of AGO2 were related to the risk of nasopharyngeal carcinoma (NPC).

View SamplesThe colorectal adenoma-carcinoma sequence describes the stepwise progression from normal to dysplastic epithelium and then to carcinoma; only a small proportion of colorectal adenoma (CRA) progresses to colorectal carcinoma (CRC). Presently, endoscopic intervention is used on patients with CRAs of high grade dysplasia, diameters > 1 cm, or villous components > 25% who are at higher risk than other CRA sufferers. During the process, biopsy samples were taken for conventional histological diagnosis, but poor pathomorphological sensitivity and specificity greatly limit the diagnostic accuracy. Unfortunately, there are no reliable molecular criteria available that can predict the potential development of CRA to CRC. In present study, we use microarrays to detail the global programme of gene expression underlying the gradual progress of colorectal adenoma-carcinoma sequence.
Identification of an intermediate signature that marks the initial phases of the colorectal adenoma-carcinoma transition.
