Matrix Metalloproteinases Accelerate Pericellular Matrix Breakdown And Disrupt Mechanotransduction In Osteoarthritis, Jule Nieuwstraten, Rosa Riester, Ulf Krister Hofmann, Farshid Guilak, Marina Danalache

2020-Current year OA Pubs

The pericellular matrix (PCM) is a specialized, narrow matrix surrounding each chondrocyte in articular cartilage, together constituting the chondron - the fundamental metabolic and functional unit of cartilage. The PCM plays a vital role in mediating biomechanical and biochemical signals essential for chondrocyte function. In osteoarthritis (OA), a chronic joint disorder characterized by progressive cartilage degradation, the PCM is one of the earliest sites of catabolic degradation, primarily driven by matrix metalloproteinases (MMPs). This study aims to investigate the functional relationship between PCM degradation and chondrocyte mechanosignaling, with an emphasis on MMP-driven changes in mechanotransduction in osteoarthritic cartilage. Human chondrons …

Reprogramming Aerobic Metabolism Mitigates Streptococcus Pyogenes Tissue Damage In A Mouse Necrotizing Skin Infection Model, Wei Xu, Tara R Bradstreet, Zongsen Zou, Suzanne Hickerson, Yuan Zhou, Hongwu He, Brian T Edelson, Michael G Caparon

2020-Current year OA Pubs

Disease tolerance is a host response to infection that limits collateral damage to host tissues while having a neutral effect on pathogen fitness. Previously, we found that the pathogenic lactic acid bacterium Streptococcus pyogenes manipulates disease tolerance using its aerobic mixed-acid fermentation pathway via the enzyme pyruvate dehydrogenase, but the microbe-derived molecules that mediate communication with the host's disease tolerance pathways remain elusive. Here we show in a murine model that aerobic mixed-acid fermentation inhibits the accumulation of inflammatory cells including neutrophils and macrophages, reduces the immunosuppressive cytokine interleukin-10, and delays bacterial clearance and wound healing. In infected macrophages, the …

Extensive Epigenomic Dysregulation Is A Hallmark Of Homologous Recombination Deficiency In Triple-Negative Breast Cancer, Youdinghuan Chen, Lucas A Salas, Jonathan D Marotti, Nicole P Jenkins, Chao Cheng, Todd W Miller, Arminja N Kettenbach, Brock C Christensen

Faculty, Staff and Students Publications

Triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype with substantial disease heterogeneity, limited treatment options, and dismal clinical outcomes. Some TNBCs display homologous recombination deficiency (HRD), a phenotype with elevated genomic burden and worse prognosis if left untreated but chemotherapeutic sensitivity. While the molecular landscape of TNBC is distinct from other breast cancer subtypes, the TNBC-specific link between HRD and epigenome-wide methylation has not been established. This study reports two independent cohorts of TNBC tumors (n = 32 and n = 58) with HRD and epigenomic landscapes measured by the Multiplex Ligation-dependent Probe Amplification assay and the …

BACKGROUND: Scalable identification of patients with post-acute sequelae of COVID-19 (PASC) is challenging due to a lack of reproducible precision phenotyping algorithms, which has led to suboptimal accuracy, demographic biases, and underestimation of the PASC.

METHODS: In a retrospective case-control study, we developed a precision phenotyping algorithm for identifying cohorts of patients with PASC. We used longitudinal electronic health records data from over 295,000 patients from 14 hospitals and 20 community health centers in Massachusetts. The algorithm employs an attention mechanism to simultaneously exclude sequelae that prior conditions can explain and include infection-associated chronic conditions. We performed independent chart reviews …

In the developing mammalian heart, the endocardium and the myocardium are separated by so-called cardiac jelly. Communication between the endocardium and the myocardium is essential for cardiac morphogenesis. How membrane-localized receptors and ligands achieve interaction across the cardiac jelly is not understood. Working in developing mouse cardiac morphogenesis models, we used a variety of cellular, imaging, and genetic approaches to elucidate this question. We found that myocardium and endocardium interacted directly through microstructures termed tunneling nanotube-like structures (TNTLs). TNTLs extended from cardiomyocytes (CMs) to contact endocardial cells (ECs) directly. TNTLs transported cytoplasmic proteins, transduced signals between CMs and ECs, and …

Comprehensive Cross-Sectional And Longitudinal Comparisons Of Plasma Glial Fibrillary Acidic Protein And Neurofilament Light Across Ftd Spectrum Disorders, Udit Sheth, Nupur Ghoshal, Et Al.

2020-Current year OA Pubs

BACKGROUND: Therapeutic development for frontotemporal dementia (FTD) is hindered by the lack of biomarkers that inform susceptibility/risk, prognosis, and the underlying causative pathology. Blood glial fibrillary acidic protein (GFAP) has garnered attention as a FTD biomarker. However, investigations of GFAP in FTD have been hampered by symptomatic and histopathologic heterogeneity and small cohort sizes contributing to inconsistent findings. Therefore, we evaluated plasma GFAP as a FTD biomarker and compared its performance to that of neurofilament light (NfL) protein, a leading FTD biomarker.

METHODS: We availed ARTFL LEFFTDS Longitudinal Frontotemporal Lobar Degeneration (ALLFTD) study resources to conduct a comprehensive cross-sectional and …

The Role Of Electrophysiologic Study In Device Selection For Leadless Atrial Pacing, Joshua R Hirsch, Jordan M Gales, Irakli Giorgberidze, Hamid Afshar

The Texas Heart Institute Journal

The AVEIR DR (Abbott Medical) was the first dual-chamber leadless pacing system approved by the US Food and Drug Administration. Many patients with sinus node dysfunction have physiologically normal atrioventricular conduction, so an atrial-only pacing system may be appropriate for them. Three patients with symptomatic sinus node dysfunction underwent device implantation with electrophysiologic study, including incremental atrial pacing until loss of 1:1 atrioventricular conduction (atrioventricular Wenckebach cycle length) and His-ventricular interval measurement. If the atrioventricular Wenckebach cycle length was no more than 400 milliseconds and the His-ventricular interval measurement was no more than 55 milliseconds, single-chamber atrial implantation was deemed …

Persistent organic pollutants (POPs) are lipophilic environmental contaminants accumulated in the adipose tissue. Weight loss interventions, such as bariatric surgery, can mobilize POPs from adipose tissue into the bloodstream. We hypothesized that this mobilization could contribute to increases in blood pressure among 57 adolescents with severe obesity undergoing bariatric surgery. POPs and metabolic features were measured from visceral adipose tissue collected during surgery using gas and liquid chromatography, coupled with high-resolution mass spectrometry. Blood pressure was assessed at baseline, 6 months, and 5 years post-surgery. We used quantile g-computation to estimate associations of POP mixtures with blood pressure changes. With …

Recessive Genetic Contribution To Congenital Heart Disease In 5,424 Probands, Weilai Dong, Sheng Chih Jin, Et Al.

2020-Current year OA Pubs

Variants with large effect contribute to congenital heart disease (CHD). To date, recessive genotypes (RGs) have commonly been implicated through anecdotal ascertainment of consanguineous families and candidate gene-based analysis; the recessive contribution to the broad range of CHD phenotypes has been limited. We analyzed whole exome sequences of 5,424 CHD probands. Rare damaging RGs were estimated to contribute to at least 2.2% of CHD, with greater enrichment among laterality phenotypes (5.4%) versus other subsets (1.4%). Among 108 curated human recessive CHD genes, there were 66 RGs, with 54 in 11 genes with >1 RG, 12 genes with 1 RG, and …
