We have previously shown that Heparin (Hep) significantly inhibited Enterovirus 71 (EV71) infection and binding in both Vero and a human neural cell line, SK-N-SH, in vitro. Therefore, in this study we intended to gain insight into the cellular and molecular mechanisms of action of Hep against clinical EV71 infection in neural cells. Instead of stating a long list of gene functions and pathways, we tried to select for EV71-induced genes that were exclusively affected by antiviral activity of Hep through a multi-level comparison and characterization.

View SamplesMost FDA approved drugs are not equally effective in all patients, suggesting that identification of biomarkers to predict responders to a chemoprevention agent will be needed to stratify patients and achieve maximum benefit. The goal of this study was to investigate both patient specific and cell-context specific heterogeneity of metformin response, using cancer cell lines fibroblast cell lines and induced pluripotent stem cells differentiated into lung epithelial lineages.

View SamplesMyelodysplastic syndromes (MDS) are a heterogeneous group of hematopoietic stem cell diseases characterized by dysplasia of one or more hematologic lineages and a high-risk of developing acute myeloid leukemia (AML). MDS patients have recurrent bacterial infections and abnormal expression of CD56 by monocytes. We investigated MDS patients’ bone marrow CD56+/CD56- monocytes and their in vitro derived dendritic cell (DCs) populations in comparison to cells obtained from disease-free subjects. We found that monocytes from MDS patients, irrespective of CD56 expression, have reduced phagocytosis activity and low expression of genes involved in triggering immune responses, regulation of immune and inflammatory response signaling pathways, and in the response to lipopolysaccharide. Dendritic cells (DCs) derived in vitro from MDS monocytes failed to develop dendritic projections and had reduced expression of HLA-DR and CD86 suggesting that antigen processing and T cell activation capabilities are impaired. In conclusion, we identified in both CD56+ and CD56- monocytes from MDS-patients several abnormalities that may be related to the increased susceptibility to infections observed in these patients.

View SamplesMedulloblastoma is a malignant brain tumor that occurs predominantly in children. Current risk stratification based on the clinical parameters is inadequate for accurate prognostication. In order to get a better understanding of medulloblastoma biology, miRNA profiling of medulloblastomas was carried out in parallel with the expression profiling of protein- coding genes.

View SamplesIt is unknown whether human lung T cells recirculate or belong to a distinct tissue-specific population. This issue is important for understanding their role in protection against viral infection and their contribution to pathophysiology of lung diseases such as chronic obstructive pulmonary disease. By comparing transcriptional profiles of blood and lung CD8+ T cells, we aimed to reveal specific traits of lung CD8+ T cells.

View SamplesEpigenetic mechanisms play an important role in the cellular development and maintenance of cellular homeostasis. Any alteration of epigenetic mechanisms via the changes in DNA methylation and histone modification may lead to various diseases including cancer. The differential expression of histone modifiers has been observed in various malignancies.
