Investigating proteogenomic divergence in patient-derived xenograft models of ovarian cancer.

Sci Rep

January 2025

Department of Laboratory Medicine and Pathology, University of Minnesota School of Medicine, 420 Delaware St SE, MMC 609, Minneapolis, MN, 55455, USA.

Within ovarian cancer research, patient-derived xenograft (PDX) models recapitulate histologic features and genomic aberrations found in original tumors. However, conflicting data from published studies have demonstrated significant transcriptional differences between PDXs and original tumors, challenging the fidelity of these models. We employed a quantitative mass spectrometry-based proteomic approach coupled with generation of patient-specific databases using RNA-seq data to investigate the proteogenomic landscape of serially-passaged PDX models established from two patients with distinct subtypes of ovarian cancer.

Introduction: The placenta produces corticotrophin releasing hormone (CRH), which rises exponentially in maternal plasma across pregnancy. CRH plays a functional role in fetal development, labor initiation, and the regulation of gestational length. We aimed to understand how maternal plasma CRH during pregnancy reflects placental physiology during parturition by characterizing placental transcriptomic signatures of maternal plasma CRH and comparing to transcriptomic signatures of gestational age at birth.

Son of a beach: Coastal development and the loss of natural beaches over time (1919 to 2018) on Okinawa Island, southern Japan.

Mar Pollut Bull

January 2025

Molecular Invertebrate Systematics and Ecology Laboratory, Faculty of Science, University of the Ryukyus, 1 Senbaru, Nishihara, Okinawa 903-0213, Japan; Tropical Biosphere Research Center, University of the Ryukyus, 1 Senbaru, Nishihara, Okinawa 903-0213, Japan. Electronic address:

The coastline of Okinawa Island, Japan, has been affected by human-made alterations for decades, often from land reclamation and coastal defense construction. Here, we use an Imperial Japanese Army map made between 1919 and 1921 to describe the composition of the Okinawan coastline approximately 100 years ago, and by overlapping this old map with a modern-day map of Okinawa (2018), we identified 131 sites where coastlines showed clear human-made alterations. For these sites, we examined what kinds of ecosystems were lost and what has replaced them.

Background: Differences in cannabinoid metabolism and patient responses can arise even with equivalent doses and formulations. Genetic polymorphisms in genes responsible for cannabinoid metabolism and medications that alter CYP450 pathways responsible for metabolism of cannabinoids may account for some of this variability.

Materials And Methods: A retrospective chart review was conducted on a cohort of unselected patients who had previously completed pharmacogenomic testing and reported oral cannabis use, as defined as "oral" or "by mouth" route of administration.

Background: PSEN1, PSEN2, and APP mutations cause Alzheimer's disease (AD) with an early age at onset (AAO) and progressive cognitive decline. PSEN1 mutations are more common and generally have an earlier AAO; however, certain PSEN1 mutations cause a later AAO, similar to those observed in PSEN2 and APP.

Methods: We examined whether common disease endotypes exist across these mutations with a later AAO (~ 55 years) using hiPSC-derived neurons from familial Alzheimer's disease (FAD) patients harboring mutations in PSEN1, PSEN2, and APP and mechanistically characterized by integrating RNA-seq and ATAC-seq.

Hornworts, one of the three bryophyte phyla, show some of the deepest divergences in extant land plants, with some families separated by more than 300 million years. Previous hornwort genomes represented only one genus, limiting the ability to infer evolution within hornworts and their early land plant ancestors. Here we report ten new chromosome-scale genomes representing all hornwort families and most of the genera.

Point-of-care ultrasound (POCUS) has emerged as a standard of care across a variety of healthcare settings due to its ability to provide critical clinical information and as well as procedural guidance to clinicians directly at the bedside. Implementation of enterprise imaging (EI) strategies is needed such that POCUS images can be appropriately captured, indexed, managed, stored, distributed, viewed, and analyzed. Because of its unique workflow and educational requirements, reliance on traditional order-based workflow solutions may be insufficient.

Although a large body of work has explored the mechanisms underlying metaphor comprehension, less research has focused on spontaneous metaphor production. Previous research suggests that reasoning about analogies can induce a relational mindset, which causes a greater focus on underlying abstract similarities. We explored how inducing a relational mindset may increase the tendency to use metaphors to describe topics.

ZIC1 is a context-dependent medulloblastoma driver in the rhombic lip.

Nat Genet

January 2025

Department of Laboratory Medicine and Pathobiology, University of Toronto, Toronto, Ontario, Canada.

Transcription factors are frequent cancer driver genes, exhibiting noted specificity based on the precise cell of origin. We demonstrate that ZIC1 exhibits loss-of-function (LOF) somatic events in group 4 (G4) medulloblastoma through recurrent point mutations, subchromosomal deletions and mono-allelic epigenetic repression (60% of G4 medulloblastoma). In contrast, highly similar SHH medulloblastoma exhibits distinct and diametrically opposed gain-of-function mutations and copy number gains (20% of SHH medulloblastoma).
