Persistent Respiratory syncytial virus (RSV) infection in humans, animal models and cell lines have proven persistence of viral genomic RNA and mRNA for long periods of time. Cell lines are well-established models that can be used to study alterations in the expression profile of the host genome. We postulate that RSV persistence might also indirectly induce changes in the homeostasis of non-infected cells through soluble factors. Thus, we evaluated the effect of conditioned medium (CM) from MP cultures on the transcriptional profile of non-infected macrophages through gene expression microarrays

View SamplesIntracellular progesterone receptor (PR) presents two main isoforms: PR-A and PR-B with different function and regulation. Both isoforms have been identified in astrocytomas, the most common and aggressive primary brain tumors in humans. To investigate the role of PR activity in the regulation of gene expression pattern of U373 cells, we evaluated by microarray analysis the profile of genes regulated by progesterone (10 nM), by a progesterone receptor antagonist (RU486, 10 M) or by both steroids.

View SamplesCopper-based chemotherapeutic compounds Casiopeinas, have been presented as able to promote selective programmed cell death in cancer cells, thus being proper candidates for targeted cancer therapy. DNA fragmentation and apoptosis -in a process mediated by reactive oxygen species- for a number of tumor cells, have been argued to be the main mechanisms. However, a detailed functional mechanism (a model) is still to be defined and interrogated for a wide variety of cellular conditions; before establishing settings and parameters needed for their wide clinical application.

View SamplesThe type II transmembrane serine protease, TMPRSS2, which is expressed in the epithelia of the respiratory tract and can activate varieties of respiratory viruses. We have generated TMPRSS2 knockout (KO) mice. These mice showed normal development, growth, and fertility phenotypes, compared with wild-type mice.

View SamplesKLF3, a member of the Krppel-like factor (KLF) family, is expressed in a wide range of cell types. It is involved in hematopoiesis of several blood cell lineages including erythrocyte and B lymphocyte. However, the research of regulatory roles on hematopoiesis of KLF3 in K562 cells has been still largely limited. To comprehensively assess the regulatory roles of KLF3 on hematopoiesis in K562 cells, a microarray analysis was performed in KLF3-deficient K562 cells. The differentially expressed genes were applied to IPA analysis to observe the perturbed hematopoiesis-associated functions, networks, and molecular pathways. This study will extensively assess the regulatory roles of KLF3 on hematopoiesis in K562 cells.

View SamplesCD8+ T cells are pre-programmed for cytotoxic differentiation. However, a subset of effector CD8+ T cells (Tc17) produce IL-17 and fail to express cytotoxic genes. Here, we show that the transcription factors directing IL-17 production inhibit cytotoxicity despite persistent Runx3 expression. Cytotoxic gene repression did not require the transcription factor Thpok. We further show that STAT3 restrained cytotoxic gene expression in CD8+ T cells and that RORgt represses cytotoxic genes by inhibiting the functions but not the expression of the cytotoxic transcription factors T-bet and Eomesodermin. Thus, the transcriptional circuitry directing IL-17 expression inhibits cytotoxic functions.
