How cell-to-cell copy number alterations that underpin genomic instability
Abstract Endometrial carcinoma, the most common gynaecological cancer, develops from endometrial epithelium which is composed of secretory and ciliated cells. Pathologic classification unreliable there a need for prognostic tools. We used single cell sequencing to study organoid model systems derived normal endometrium discover novel markers specific or A marker cells (MPST) several (FAM92B, WDR16, DYDC2) were validated by immunohistochemistry on organoids tissue sections. performed ovarian...
<h3>Importance</h3> Allelic variation in the brain-derived neurotrophic factor (<i>BDNF</i>) Val66Met polymorphism moderates increases cerebrospinal fluid (CSF) levels of tau and phosphorylated 181 (p-tau181), measured using immunoassay, cognitive decline presymptomatic dominantly inherited Alzheimer disease (DIAD). Advances mass spectrometry show that CSF phosphorylation occupancy at threonine 217 (p-tau181/tau181, p-tau217/tau217) with initial β-amyloid (Aβ) aggregation, while 205...
Abstract Neurofilament light chain, a putative measure of neuronal damage, is measurable in blood and CSF predictive cognitive function individuals with Alzheimer’s disease. There has been limited prior work linking neurofilament functional connectivity, no investigated associations connectivity autosomal dominant Here, we assessed relationships between light, cognition, cross-sectional sample 106 disease mutation carriers 76 non-carriers. We employed an innovative network-level enrichment...
Abstract Purpose: Shallow whole-genome sequencing (sWGS) can detect copy-number (CN) aberrations. In high-grade serous ovarian cancer (HGSOC) sWGS identified CN signatures such as homologous recombination deficiency (HRD) to direct therapy. We applied with targeted p53abn endometrial cancers identify additional prognostic stratification and therapeutic opportunities. Experimental Design: panel was performed on formalin-fixed, paraffin-embedded cancers. alterations, mutational data were...
Abstract Background PSEN1, PSEN2, and APP mutations cause Alzheimer’s disease (AD) with an early age at onset (AAO) progressive cognitive decline. PSEN1 are more common generally have earlier AAO; however, certain a later AAO, similar to those observed in PSEN2 . Methods We examined whether endotypes exist across these AAO (~ 55 years) using hiPSC-derived neurons from familial (FAD) patients harboring A79V , N141I V717I mechanistically characterized by integrating RNA-seq ATAC-seq. Results...
Low-grade serous ovarian carcinoma (LGSC) is a rare and lethal subtype of cancer. LGSC pathologically, biologically, clinically distinct from the more common high-grade (HGSC). arises borderline tumours (SBTs). The mechanism transformation for SBTs to remains poorly understood. To better understand biology LGSC, we performed whole proteome profiling formalin-fixed, paraffin-embedded tissue blocks (n = 11), HGSC 19), 26). We identified that able distinguish between histotypes epithelial...
Abstract Hereditary diffuse gastric cancer (HDGC) is a syndrome caused by germline variants in CDH1 , the gene encoding cell–cell adhesion molecule E‐cadherin. Loss of E‐cadherin associated with cellular dedifferentiation and poor prognosis, but mechanisms through which loss initiates HDGC are not known. Using single‐cell RNA sequencing, we explored transcriptional landscape murine organoid model to characterize impact early tumourigenesis. Progenitor populations stratified squamous simple...
DICER1 is an RNase III enzyme essential for miRNA biogenesis through cleaving precursor-miRNA hairpins. Germline loss-of-function mutations underline the development of syndrome, a rare genetic disorder that predisposes children to cancer in organs such as lung, gynecologic tract, kidney, and brain. Unlike classical tumor suppressors, somatic "second hit" syndrome-associated cancers does not fully inactivate but impairs its IIIb activity only, suggesting noncanonical two-hit hypothesis....
We report the generation of a gene-edited human induced pluripotent stem cell (iPSC) line from an Alzheimer's disease patient-derived iPSC harbouring PSEN1 H163R mutation. This demonstrates morphology, expression pluripotency markers, and maintains normal karyotype.
ABSTRACT Structural genome alterations are determinants of cancer ontogeny and therapeutic response. While bulk sequencing has enabled delineation structural variation (SV) mutational processes which generate patterns DNA damage, we have little understanding how these lead to cell-to-cell variations underlie selection rates accrual different genomic lesions. We analysed 309 high grade serous ovarian triple negative breast genomes determine their processes, selecting 22 from sequenced...
Wikipedia is one of the most important channels for public communication science and frequently accessed as an educational resource in computational biology. Joint efforts between International Society Computational Biology (ISCB) taskforce WikiProject Molecular (a group expert editors) have considerably improved biology representation on recent years. However, there still urgent need further improvement quality, especially when compared to related scientific fields such genetics medicine....
