There is mounting evidence that microbes residing in the human intestine contribute to diverse alcohol-associated liver diseases (ALD) including most deadly form known as hepatitis (AH). However, mechanisms by which gut synergize with excessive alcohol intake promote injury are poorly understood. Furthermore, whether drugs selectively target microbial metabolism can improve ALD has never been tested. We used liquid chromatography tandem mass spectrometry quantify levels of microbe and host...

Abstract The microenvironment that surrounds pancreatic ductal adenocarcinoma (PDAC) is profoundly desmoplastic and immunosuppressive. Understanding triggers of immunosuppression during the process tumorigenesis would aid in establishing targets for effective prevention therapy. Here, we interrogated differential molecular mechanisms dependent on cell origin subtype promote PDAC initiation established tumors. Transcriptomic analysis cell-of-origin–dependent epithelial gene signatures...

Pancreatic ductal adenocarcinoma (PDAC) presents a 5-year overall survival rate of 11%, despite efforts to improve clinical outcomes in the past two decades. Therapeutic resistance is hallmark this disease, due its dense and suppressive tumor microenvironment (TME). Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) promising local ablative potential immunomodulatory therapy for PDAC. In study, we performed RFA preclinical tumor-bearing KrasG12D; Trp53R172H/+; Pdx1:Cre (KPC)...

Complement plays a crucial role in microbial defense and clearance of apoptotic cells. Emerging evidence suggests complement is an important contributor to alcoholic liver disease. While component 1, Q subcomponent (C1q)-dependent activation contributes ethanol-induced injury, the alternative pathway injury unknown. Activation via classical pathways was detected hepatitis patients. Female C57BL/6J [wild type (WT)], C1q-deficient ( C1qa −/− , lacking activation), protein 4-deficient C4 lectin...

Given the lack of effective therapies and high mortality in acute alcohol-associated hepatitis (AH), it is important to develop rationally designed biomarkers for disease management. Complement, a critical component innate immune system, contributes uncontrolled inflammatory responses leading liver injury, but also involved hepatic regeneration. Here, we investigated whether panel complement proteins activation products would provide useful severity AH aid predicting 90-day mortality.

Mitophagy removes damaged mitochondria to maintain cellular homeostasis. Aryl hydrocarbon receptor (AhR) expression in the liver plays a crucial role supporting normal functions, but its impact on mitochondrial function is unclear. Here, we identified new of AhR regulation mitophagy control hepatic energy

Trovafloxacin (TVX) is a drug that has caused idiosyncratic, drug-induced liver injury (IDILI) in humans. In murine model of IDILI, otherwise nontoxic doses TVX and the inflammagen lipopolysaccharide (LPS) interacted to produce pronounced hepatocellular injury. The depended on TVX-induced, small but significant prolongation tumor necrosis factor-<i>α</i> (TNF) appearance plasma. enhancement TNF expression by was reproduced vitro RAW 264.7 macrophages (RAW cells) stimulated with LPS. current...

Acute and chronic alcohol abuse has adverse impacts on both the innate adaptive immune response, which may result in reduced resistance to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection promote progression of coronavirus disease 2019 (COVID-19). However, there are no large population-based data evaluating potential causal associations between consumption COVID-19.We conducted a Mendelian randomization study using from UK Biobank explore association risk SARS-CoV-2...

Trovafloxacin (TVX) is a fluoroquinolone antibiotic known to cause idiosyncratic, drug-induced liver injury (IDILI) in humans. The mechanism underlying this toxicity remains unknown. Previously, an animal model of IDILI mice revealed that TVX synergizes with inflammatory stress from bacterial lipopolysaccharide (LPS) produce hepatotoxic interaction. required prolongation the appearance tumor necrosis factor-<i>α</i> (TNF) plasma. results presented here describe TVX/LPS coexposure RAW 264.7...

Increased body mass index (BMI) and metabolic abnormalities are controversial prognostic factors of lung cancer. However, the relationship between overweight/obesity phenotypes hospital readmission in patients with cancer is rarely reported.We established a retrospective cohort using United States (US) Nationwide Readmissions Database (NRD).
