- The phenotype of a cell and its underlying molecular state is strongly influenced by extracellular signals, including growth factors, hormones, and extracellular matrix proteins. While these signals are normally tightly controlled, their dysregulation leads to phenotypic and molecular states associated with diverse diseases. To develop a detailed understanding of the linkage between molecular and phenotypic changes, we generated a comprehensive dataset that catalogs the transcriptional, proteomic, epigenomic and phenotypic responses of MCF10A mammary epithelial cells after exposure to the ligands EGF, HGF, OSM, IFNG, TGFB and BMP2. Systematic assessment of the molecular and cellular phenotypes induced by these ligands comprise the LINCS Microenvironment (ME) perturbation dataset, which has been curated and made publicly available for community-wide analysis and development of novel computational methods ( synapse.org/LINCS_MCF10A ). In illustrative analyses, we demonstrate how this dataset can be used to discover functionally related molecular features linked to specific cellular phenotypes. Beyond these analyses, this dataset will serve as a resource for the broader scientific community to mine for biological insights, to compare signals carried across distinct molecular modalities, and to develop new computational methods for integrative data analysis.

Research review (peer-reviewed)abstract
- The Cancer Genome Atlas (TCGA) Research Network has profiled and analyzed large numbers of human tumors to discover molecular aberrations at the DNA, RNA, protein and epigenetic levels. The resulting rich data provide a major opportunity to develop an integrated picture of commonalities, differences and emergent themes across tumor lineages. The Pan-Cancer initiative compares the first 12 tumor types profiled by TCGA. Analysis of the molecular aberrations and their functional roles across tumor types will teach us how to extend therapies effective in one cancer type to others with a similar genomic profile. © 2013 Nature America, Inc.

- The present study determined mutations of phosphatase and tensin homolog (PTEN) gene in patients suffering from high-grade gliomas (WHO grades III and IV) and further investigated the mutations in correlation to patients' histopathological classification and short-term survival. Total RNA and genomic DNA were extracted from tumor tissues. Full-length PTEN cDNA sequences were amplified by polymerase chain reaction (PCR). The PCR products were directly sequenced, and the PTEN mutations were analyzed. It demonstrated that the incidence of PTEN mutations was 8/22 in these patients: one patient with WHO grade III glioma (1/11) and 7 patients with WHO grade IV glioma (7/11). Most patients had three or more mutations in the PTEN gene, with exons 2, 3, 4, 5, 6 and 7 as hot mutation regions, with mutation incidence from 62.5% to 75%. About 68.4% of mutations were missense, 26.3% same-sense and 5.3% nonsense mutations. The median survival times of the WHO grade III and IV groups were 250 and 53 weeks after surgery, respectively (p=0.016). The 36-week survival rate of patients with and without PTEN mutations was 62.5% and 92.9% (p=0.038, odds ratio=7.80), respectively. The present study suggests that PTEN mutations are late events in the malignant progression of glioma and the occurrence of PTEN mutations are significantly correlated to patients' short-term survival.

Journal article (peer-reviewed)abstract
- Objective: This study aimed to investigate the association between alcohol consumption and the prevalence of stroke in Chinese adults aged 40 years and over.Method: We conducted a cross-sectional analysis among 113,573 Chinese adults aged >= 40 years in the China National Stroke Prevention Project (2014-2015) to examine correlations of alcohol consumption with the prevalence of stroke. Logistic regression models were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs), controlling for various confounders, e.g., gender, age, smoking, physical activity and other health conditions.Results: Within the study population, a total of 12,753 stroke survivors were identified. The prevalence of light to moderate and of heavy alcohol consumption was 10.1% and 5.7% respectively. The multivariate logistic regression results show that light to moderate alcohol consumption was associated with reduced risk of stroke of all types [0.91 (95%CI: 0.85-0.97)] and of ischemic stroke [0.90 (0.84-0.97)]. No association was found between alcohol consumption and hemorrhagic stroke. Compared with abstainers, the adjusted ORs of all stroke were 0.83 (0.75-0.92) for those who drank 11-20 years, and no association was found between 1 and 10 years or over 20 years of drinking and risk of stroke.Conclusions: These results indicate that light to moderate alcohol consumption may be protective against all and ischemic stroke, and heavy drinking was not significantly associated with risk of all stroke in China. No association between alcohol consumption and hemorrhagic stroke was found.
