Description
The unprecedented magnitude of the 2013-2016 Makona Ebola virus (M-EBOV) epidemic likely resulted from multiple epidemiologic factors that set it apart from previous outbreaks. Nonetheless, genetic adaptations that distinguish M-EBOV from previous isolates may also have contributed to the scale of the epidemic. Of particular interest is a M-EBOV glycoprotein (GP) variant, GP-A82V, that was first detected at the inflection point of the 2013-2016 outbreak - when the number of cases increased exponentially - and which completely supplanted the earlier M-EBOV sequence. We found that, as compared with the earlier strain, GP-A82V increased the ability of M-EBOV to fuse with and infect cells of primate origin, including human blood dendritic cells, without altering innate immune signaling in target cells. Residue 82 is located at the NPC1-binding site on M-EBOV GP and the increased infectivity of GP-A82V was restricted to cells from species in which the NPC1 orthologue bears primate-defining residues at the critical interface. We utilized HIV-derived lentiviral vectors pseudotyped with founder and A82V containing M-EBOV GPs to explore the potential that this modification alters how human monocyte-derived dendritic cells (MDDCs) respond to EBOV GP stimulation. Overall design: We generated stocks of lentiviral vector bearing one the following three M-EBOV GPs: founder, A82V, and A82V/T230A. These viral stocks were used to challenge MDDCs from two healthy, anonymous human donors. Stimulated MDDCs were harvested at 1, 2, 4, and 6 hours after viral addition. Gene expression in M-EBOV GP challenged MDDCs was compared to a unstimulated control.

Description
Maternal obesity during pregnancy leads to a pro-inflammatory milieu in the placenta. We conducted a global transcriptomic profiling in BeWo cells following palmitic acid (PA, 500 uM) and/or TNF-alpha (10 ng/ml) treatment for 24 h. Microarray analysis revealed that placental cytotrophoblasts increased expression of genes related to inflammation, stress response and immediate-early factors in response to plamitic acid, TNF-alpha or a combination of both. Our results suggest that fatty acids and inflammatory cytokines induce inflammation in placental cells via activation of JNK-Egr-1 signaling.

Description
Frankincense oil is prepared from aromatic hardened wood resin obtained by tapping Boswellia trees. For thousands of years, it has been important both socially and economically as an ingredient in incense and perfumes. Frankincense oil is a botanical oil distillate made from fermented plants that contains boswellic acid, a component known to have anti-neoplastic properties. We evaluated frankincense oil-induced cytotoxicity in bladder cancer cells. With a window of concentration, frankincense oil suppressed cell viability and induced cytotoxicity in bladder transitional carcinoma J82 cells but not normal bladder urothelial UROtsa cells immortalized with SV40 large T antigen. However, frankincense oil-induced J82 cell death did not result in DNA fragmentation. Microarray and bioinformatics analysis confirmed that frankincense oil activated cell cycle arrest, suppressed cell proliferation, and activated apoptosis in J82 cells through a series of potential pathways. These finding suggest that bladder cancer can be treated through intravesical administration of pharmaceutical agents similar to direct application on melanoma.

Description
Myocyte enhancer factor 2B (MEF2B) is a transcription factor with somatic mutation hotspots at K4, Y69 and D83 in diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL). The recurrence of these mutations indicates that they may drive lymphoma development. However, inferring the mechanisms by which they may drive lymphoma development was complicated by our limited understanding of MEF2Bs normal functions. To expand our understanding of the cellular activities of wildtype (WT) and mutant MEF2B, I developed and addressed two hypotheses: (1) identifying genes regulated by WT MEF2B will allow identification of cellular phenotypes affected by MEF2B activity and (2) contrasting the DNA binding sites, effects on gene expression and effects on cellular phenotypes of mutant and WT MEF2B will help refine hypotheses about how MEF2B mutations may contribute to lymphoma development. To address these hypotheses, I first identified genome-wide WT MEF2B binding sites and transcriptome-wide gene expression changes mediated by WT MEF2B. Using these data I identified and validated novel MEF2B target genes. I found that target genes of MEF2B included the cancer genes MYC, TGFB1, CARD11, NDRG1, RHOB, BCL2 and JUN. Identification of target genes led to findings that WT MEF2B promotes expression of mesenchymal markers, promotes HEK293A cell migration, and inhibits DLBCL cell chemotaxis. I then investigated how K4E, Y69H and D83V mutations change MEF2Bs activity. I found that K4E, Y69H and D83V mutations decreased MEF2B DNA binding and decreased MEF2Bs capacity to promote gene expression in both HEK293A and DLBCL cells. These mutations also reduced MEF2Bs capacity to alter HEK293A and DLBCL cell movement. From these data, I hypothesize that MEF2B mutations may promote DLBCL and FL development by reducing expression of MEF2B target genes that would otherwise function to help confine germinal centre B-cells to germinal centres. Overall, my research demonstrates how observations from genome-scale data can be used to identify cellular effects of candidate driver mutations. Moreover, my work provides a unique resource for exploring the role of MEF2B in cell biology: I map for the first time the MEF2B regulome, demonstrating connections between a relatively understudied transcription factor and genes significant to oncogenesis.
