BACKGROUND The P4 strain of the corn smut fungus, Ustilago maydis, secretes a fungal toxin, KP4, encoded by a fungal virus (UMV4) that persistently infects its cells. UMV4, unlike most other (non-fungal) viruses, does not spread to uninfected cells by release into the extracellular milieu during its normal life cycle and is thus dependent upon host survival(More)
RATIONALE Yes-associated protein (YAP), the nuclear effector of Hippo signaling, regulates cellular growth and survival in multiple organs, including the heart, by interacting with TEA (transcriptional enhancer activator)-domain sequence-specific DNA-binding proteins. Recent studies showed that YAP stimulates cardiomyocyte proliferation and survival.(More)
The primary functions of most virus capsids are to protect the viral genome in the extra-cellular milieu and deliver it to the host. In contrast, the capsids of fungal viruses, like the cores of all other known double stranded RNA viruses, are not involved in host recognition but do shield their genomes, and they also carry out transcription and(More)
Mesenchymal stem cells (MSCs) are useful in tissue repair but also possess immunomodulatory properties. Murine and uncontrolled human trials suggest efficacy of MSCs in treating lupus. Autologous cells are preferable; however, recent studies suggest that lupus-derived MSCs lack efficacy in treating disease. Thus, the optimum derivation of MSCs for use in(More)
BACKGROUND DNA methylation of promoter CpG islands is associated with gene suppression, and its unique genome-wide profiles have been linked to tumor progression. Coupled with high-throughput sequencing technologies, it can now efficiently determine genome-wide methylation profiles in cancer cells. Also, experimental and computational technologies make it(More)
Transcriptional profiling is a useful strategy to study development and disease. Approaches to isolate RNA from specific cell types, or from specific cellular compartments, would extend the power of this strategy. Previous work has shown that isolation of genetically tagged ribosomes (translating ribosome affinity purification; TRAP) is an effective means(More)
Although the state space approach for estimating multilevel regression models has been well established for decades in the time series literature, it does not receive much attention from educational and psychological researchers. In this article, we (a) introduce the state space approach for estimating multilevel regression models and (b) extend the state(More)
MSC are being explored as a promising novel treatment for SLE. In this study, we: 1) assessed the differential effects of allogeneic versus syngeneic MSC transplantation on lupus-like disease, 2) explored the mechanisms by which MSC modulate disease, and 3) investigated whether lupus-derived-MSC have intrinsic immunomodulatory defects. We showed that in(More)
RATIONALE Yes-associated protein (YAP), the terminal effector of the Hippo signaling pathway, is crucial for regulating embryonic cardiomyocyte proliferation. OBJECTIVE We hypothesized that YAP activation after myocardial infarction (MI) would preserve cardiac function and improve survival. METHODS AND RESULTS We used a cardiac-specific, inducible(More)
We conducted a 1000 Genomes-imputed genome-wide association study (GWAS) meta-analysis for nicotine dependence, defined by the Fagerström Test for Nicotine Dependence in 17 074 ever smokers from five European-ancestry samples. We followed up novel variants in 7469 ever smokers from five independent European-ancestry samples. We identified genome-wide(More)
