Article Abstract
Pseudomyxoma peritonei (PMP), a rare condition characterized by mucinous ascites in the peritoneal cavity, often leads to a poor prognosis. However, omics profiling of this disease remains significantly underexplored. Here, we present single-cell transcriptomic profiling of five PMP cases to identify cell type-specific gene features associated with PMP pathogenesis. Additionally, we provide bulk RNA-seq datasets from two independent cohorts: 19 fresh frozen tissue samples (12 PMPs) and 34 formalin-fixed paraffin-embedded (FFPE) samples (25 PMPs). We also offer protein expression data from a tissue microarray (TMA) analysis of 90 samples (45 PMPs). Our single-cell and bulk transcriptomic profiles, along with TMA verifications, reveal the cellular diversity of PMP, highlighting the coexistence of epithelial and mesenchymal characteristics within PMP cells. These datasets enhance our understanding of PMP pathogenesis and provide a valuable resource for uncovering the intricate molecular landscape of PMP, with the potential to improve clinical utility through further research.

The functions of peripheral membrane proteins (PMPs) can be critically influenced by their orientations on membrane surfaces, which are inherently dynamic and challenging to characterize with precision. Molecular dynamics (MD) simulations, while powerful, face limitations in force field accuracy and sampling, particularly for systems involving intricate protein-lipid interactions. Here, we employ artifact-free membrane paramagnetic relaxation enhancement (mPRE) data as a quantitative benchmark to evaluate and refine MD simulations of KRas4B, a classical PMP, bound to anionic bilayers.

Accurately sampling the membrane-bound conformations of peripheral membrane proteins (PMP) using classical all-atom molecular dynamics simulations (AAMD) is a formidable enterprise due to the wide rugged free energy landscape of the protein-membrane system. In general, AAMD-based extraction of binding geometry requires simulations of multiple systems with different initial user-defined binding poses that may not be exhaustive. As an alternative, advanced sampling methods are also applied to elucidate the membrane-binding mechanism of PMPs.

Capillary electrophoresis (CE) is increasingly used in distributed field environmental monitoring, teaching, and citizen science. Consequently, the development of low-cost CE instruments using inexpensive components and do-it-yourself approaches has gained significant attention. Peristaltic micro-pumps (PMPs), with dimensions as small as 15 × 17 × 34 mm, offer advantages such as low cost, compact size, and energy efficiency, making them highly suitable for miniaturized CE instruments with automated flow-through injection.
