Project description:The overall study objective of this trial study is to identify and evaluate strategies to improve the accessibility of the video education with result dependent disclosure (VERDI) model, increasingly utilized as a pre-genetic testing (pretest) education alternative in clinical practice, to better serve a more diverse patient population at risk for hereditary cancers.
Project description:The primary purpose of this study is to find the recommended dose of LGK974 as a single agent and in combination with PDR001 that can be safely given to adult patients with selected solid malignancies that have progressed despite standard therapy or for which no effective standard therapy exists
Project description:In this study, we defined subgroup specific chromatin landscape (H3K27ac, H3K27me3, RNA-Seq, 27ac hichip, WGS) of medulloblastoma to identify pathogenic epigenetic alterations that regulate expression of a context dependent driver gene.
Project description:Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 primarily affects the respiratory system, but the observation of diverse neurological symptoms indicates that other organs, including the brain, may be involved. The pathophysiological mechanisms of COVID-19-associated effects on the central nervous system (CNS) have become clearer during the past two years. Nevertheless, the precise CNS-specific molecular mechanisms are still elusive and raise several questions. To further elucidate the host response at brain tissue level, we profiled single-nucleus transcriptomes and performed proteomics from olfactory mucosa, olfactory bulb, medulla oblongata and cerebellum at different timepoints of the disease in individuals who died of COVID-19 and underwent rapid autopsy.
Project description:Ethyl acetate extracts of clb+ and clbP mutant from E. coli IHE0334 clb genomic island. Files with WT = clb+ wild-type; Files labeled as "P" denotes clbP mutant. Both a peptide and unbiased isotope model was used for acquisition of MS/MS data.
Project description:Chromosomal rearrangements are a frequent cause of oncogene deregulation in human malignancies. Overexpression of EVI1 is found in a subgroup of acute myeloid leukemia (AML) with 3q26 chromosomal rearrangements which are often therapy resistant. In a cohort of primary t(3;8)(q26;q24) AML samples we observed the translocation of a MYC super-enhancer to EVI1. We generated a patient-based t(3;8)(q26;q24) model in vitro using CRISPR-Cas9 technology and demonstrated hyper-activation of EVI1 by the hijacked MYC super-enhancer. One MYC super-enhancer element in particular, which recruits early hematopoietic regulators, is critical for EVI1 expression and enhancer-promoter interaction. This interaction is facilitated by a CTCF-bound motif upstream of the EVI1 promoter that acts as an enhancer-docking site in t(3;8) AML. Genomic analyses of 3q26-rearranged AML samples point to a common mechanism by which EVI1 uses this CTCF-bound enhancer-docking site to hijack early hematopoietic enhancers.
Project description:We investigated the relationship between experience-dependent eye movements, hippocampus-dependent memory, and aware memory. We measured eye movements in young adults, older adults, and memory-impaired patients with damage to the medial temporal lobe as they viewed 120 novel scenes and 120 previously viewed scenes. Participants indicated if each scene was old or new and also gave a confidence rating for the memory judgment. Young adults and older adults explored old scenes less than they explored new scenes, but the patients did not. For the young and older adults, this effect was observed only when participants were aware of the scene's familiar or novel status. In a second experiment, young adults viewed scenes that were either new, had been viewed previously, or had been viewed previously but had been changed (i.e., an object within the scene was either added or removed). The only instructions were to pay attention to the scenes and view each scene as it appeared, and there was no expectation that memory would be tested. Directly after the first altered scene was presented, participants were asked to classify the scene as new, old, or old but changed. Participants who were aware of the manipulation preferentially viewed the changed region, but participants who were unaware did not. These findings suggest that experience-dependent eye movements reflect hippocampus-dependent (and aware) memory, even when participants have no expectation that memory is being tested; and they are consistent with the view that awareness of what is learned is a fundamental characteristic of hippocampus-dependent memory.
