Tumor suppressors RBL1 and PTEN are epigenetically silenced in IPF mesenchymal progenitor cells by a CD44/Brg1/PRMT5 regulatory complex.

The idiopathic pulmonary fibrosis (IPF) lung contains mesenchymal progenitor cells (MPCs) that display durable activation of oncogenic signaling and cell-autonomous fibrogenicity in vivo. Prior work identified a CD44/Brg1/PRMT5 nuclear regulatory module in IPF MPCs that increased the expression of genes positively regulating pluripotency and self-renewal. Left unanswered is how IPF MPCs evade negative regulation of self-renewal.

Understanding the Symptoms and Impacts Experienced by People with Relapsing-Remitting MS: A Qualitative Investigation Using Semi-Structured Interviews.

Introduction: Multiple sclerosis (MS) is a disabling disease with unpredictable clinical manifestations. As clinical assessments may not fully capture the impact of MS on quality of life, they can be complemented by patient-reported outcome (PRO) measures to provide a more comprehensive picture of MS disease state and impact. The objectives of this study were to explore the experiences of people with relapsing-remitting MS, including symptoms and impacts on daily life, and to provide a conceptual model of MS outcomes.

Brg1/PRMT5 nuclear complex epigenetically regulates FOXO1 in IPF mesenchymal progenitor cells.

We have discovered intrinsically fibrogenic mesenchymal progenitor cells (MPCs) in the human idiopathic pulmonary fibrosis (IPF) lung. IPF MPCs display a durably distinct transcriptome, suggesting that they have undergone epigenetic modifications. Prior studies indicate that the chromatin remodeler Brg1 associates with the arginine methyltransferase PRMT5 to epigenetically regulate transcription factors.

Modeling the Application of IHE QRPH Profiles in Data Integration Centers: A Practical Approach with 3LGM2.

The Data Integration Centers (DICs), all part of the German Medical Informatics Initiative (MII), prepare routine care data captured in university hospitals to enable its reuse in clinical research. Tackling this challenging task requires them to maintain multiple data stores, implement the necessary transformation processes, and provide the required terminology services, all while also addressing the use case specific needs researchers might have. An MII wide application of the standardized profiles defined in the IHE QRPH domain might therefore be able to drastically reduce the overhead at any one DIC.

The effect of disease modifying therapies on fatigue in multiple sclerosis.

Introduction: Fatigue is one of the most common and debilitating symptoms in people with multiple sclerosis (PwMS). Disease-modifying therapies (DMTs) are currently the gold standard in the treatment of MS and their effectiveness has been assessed through randomized clinical trials (RCTs). However, there is limited evidence on the impact of DMTs on fatigue in (PwMS).

SFPQ and Its Isoform as Potential Biomarker for Non-Small-Cell Lung Cancer.

Cancer markers are measurable molecules in the blood or tissue that are produced by tumor cells or immune cells in response to cancer progression. They play an important role in clinical diagnosis, prognosis, and anti-drug monitoring. Although DNA, RNA, and even physical images have been used, proteins continue to be the most common marker.

Concept for a Basic ISO 14721 Archive Information Package for Clinical Studies.

Secondary use of medical data for research is desirable for intrinsic, ethical and financial reasons. In this context, the question becomes relevant as to how such datasets are to be made accessible to a larger target group in the long term. Typically, datasets are not extracted ad hoc from the primary systems, because they are processed qualitatively (FAIR data).

IL-8 concurrently promotes idiopathic pulmonary fibrosis mesenchymal progenitor cell senescence and PD-L1 expression enabling escape from immune cell surveillance.

Idiopathic pulmonary fibrosis (IPF) is a progressive fibrotic lung disease. We discovered fibrogenic mesenchymal progenitor cells (MPCs) in the lungs of IPF patients that display cell-autonomous fibrogenicity and drive fibrotic progression. In a study of the IPF MPC nuclear proteome, we identified DNA damage as one of the most altered functions in IPF MPCs.

A comparison of the measurement properties of the PROMIS Fatigue (MS) 8a against legacy fatigue questionnaires.

Background: Amidst the growing number of patient-reported outcome (PRO) measures of fatigue being used in multiple sclerosis (MS) clinical trials and clinics, evidence-based consensus on the most appropriate and generalizable measures across different settings would be beneficial for clinical research and patient care. The objective of this research was to compare the validity and responsiveness of scores from the PROMIS Fatigue (MS) 8a with those of the Fatigue Severity Scale (FSS) and the Modified Fatigue Impact Scale (MFIS), across US and UK MS populations.

Methods: Two observational studies were performed in MS populations as part of a PRO measure development project, including a cross-sectional study in two tertiary US MS centers (n = 340) and a 96-week longitudinal study in the UK MS Register cohort (n = 352).

SFPQ Promotes Lung Cancer Malignancy Regulation of CD44 v6 Expression.

Mesenchymal stem cells (MSCs) contribute to tumor pathogenesis and elicit antitumor immune responses in tumor microenvironments. Nuclear proteins might be the main players in these processes. In the current study, combining spatial proteomics with ingenuity pathway analysis (IPA) in lung non-small cell (NSC) cancer MSCs, we identify a key nuclear protein regulator, SFPQ (Splicing Factor Proline and Glutamine Rich), which is overexpressed in lung cancer MSCs and functions to promote MSCs proliferation, chemical resistance, and invasion.

Proteomic analysis of the IPF mesenchymal progenitor cell nuclear proteome identifies abnormalities in key nodal proteins that underlie their fibrogenic phenotype.

IPF is a progressive fibrotic lung disease whose pathogenesis remains incompletely understood. We have previously discovered pathologic mesenchymal progenitor cells (MPCs) in the lungs of IPF patients. IPF MPCs display a distinct transcriptome and create sustained interstitial fibrosis in immune deficient mice.
