Risk of severe illness of COVID-19 patients with NAFLD and increased NAFLD fibrosis scores.

Background: There is still little knowledge about the association of liver fibrosis with the clinical outcomes of COVID-19 patients with non-alcoholic fatty liver disease (NAFLD). The aim of the study was to determine the association of NAFLD fibrosis score (NFS)-determined liver fibrosis with clinical outcomes of COVID-19 patients with NAFLD.

Methods: The NAFLD was diagnosed by the Hepatic Steatosis Index (HSI) in the absence of other causes of chronic liver diseases.

Upregulation of PD-1 expression on circulating CD8+ but not CD4+ T cells is associated with tuberculosis infection in health care workers.

Background: Health care workers (HCWs) are at risk for occupationally acquired Mycobacterium tuberculosis infection and tuberculosis (TB) disease due to repeated exposure to workplace tubercle bacilli. To determine whether continual mycobacterial stimulation correlates with increased expression of inhibitory T cell receptors, here we compared PD-1 receptor expression on surfaces of circulating T cells between naïve (uninfected) HCWs and HCWs with latent TB infection (LTBI).

Result: Data collected from 133 medical workers who met study selection criteria were included in the final analysis.

Nutritional status is closely related to the severity of COVID-19: a multi-center retrospective study.

We analyzed the clinical characteristics of 342 coronavirus disease 2019 (COVID-19) patients, and analyzed the relationship between the progression of COVID-19 and Nutritional status.

HSV-1-encoded ICP0 degrades the host deubiquitinase BRCC36 to antagonize interferon antiviral response.

Type I interferon (IFN-I) plays pivotal roles in defense against viral infection. HSV-1 has evolved multiple strategies to evade IFN-I antiviral response. In this study, we revealed a new mechanism that HSV-1-encoded ICP0 regulates the host deubiquitinase BRCC36 to inhibit IFN-I antiviral response.

Ubiquitin E3 ligase MID1 inhibits the innate immune response by ubiquitinating IRF3.

Interferon regulatory factor 3 (IRF3) is a critical transcription factor for inducing production of type I interferons (IFN-I) and regulating host antiviral response. Although IRF3 activation during viral infection has been extensively studied, the inhibitory regulation of IRF3 remains largely unexplored. Here, we revealed that Midline-1 (MID1) is a ubiquitin E3 ligase of IRF3 that plays essential roles in regulating the production of IFN-I.

A Transcriptional Regulatory Loop of Master Regulator Transcription Factors, PPARG, and Fatty Acid Synthesis Promotes Esophageal Adenocarcinoma.

Although obesity is one of the strongest risk factors for esophageal adenocarcinoma, the molecular mechanisms underlying this association remain unclear. We recently identified four esophageal adenocarcinoma-specific master regulator transcription factors (MRTF) ELF3, KLF5, GATA6, and EHF. In this study, gene-set enrichment analysis of both esophageal adenocarcinoma patient samples and cell line models unbiasedly underscores fatty acid synthesis as the central pathway downstream of three MRTFs (ELF3, KLF5, GATA6).

Ubiquitin E3 Ligase c-Cbl Is a Host Negative Regulator of Nef Protein of HIV-1.

Nef is an accessory protein encoded by human immunodeficiency virus type-1 (HIV-1) and plays important roles in regulating HIV-1 infection and viral replication. Interestingly, HIV-1 Nef can promote degradation of numerous host proteins to disrupt cellular antiviral immune response. However, how HIV-1 Nef is degraded by host factors remains largely unexplored.

Marein ameliorates Ang II/hypoxia-induced abnormal glucolipid metabolism by modulating the HIF-1α/PPARα/γ pathway in H9c2 cells.

The objectives of this study were to investigate the effects of marein, a major bioactive compound in functional food Coreopsis tinctoria, in hypertrophic H9c2 cells. Treating angiotensin II/hypoxia-stimulated H9c2 cells with marein led to decreasing cell surface area, intracellular total protein, atrial natriuretic peptide, and free fatty acids levels, but increasing glucose level. Marein treatment decreased hypoxia inducible factor-1α (HIF-1α), peroxisome proliferator activated receptor γ (PPARγ), medium chain acyl-coenzyme A dehydrogenase, glucose transporter-4, and glycerol-3-phosphate acyltransferase protein expressions, and increased PPARα, fatty acid transport protein-1, carnitine palmitoyltransferase-1, and pyruvate dehydrogenase kinase-4 protein expressions.

Lipid peroxidation aggravates anti-tuberculosis drug-induced liver injury: Evidence of ferroptosis induction.

Anti-tuberculosis drug-induced liver injury (ATB-DILI) is a common adverse reaction of anti-tuberculosis drug treatment. Studies have shown that isoniazid (INH) and rifampicin (RFP) are mainly metabolized in the liver and a large amount of intracellular glutathione is used up during the metabolism of these drugs, resulting in lipid peroxidation and hepatocyte death. Ferroptosis is a novel form of programmed cell death caused by iron-ion-dependent lipid peroxidation.

Previous studies reported that coronavirus disease 2019 (COVID-19) was likely to result in liver injury. However, few studies reported the impacts of COVID-19 on liver function in patients with chronic liver diseases. We aimed to describe a case series of COVID-19 patients with chronic hepatitis B virus (HBV) infection.

A novel regulatory loop miR-101/ANXA2/EGR1 mediates malignant characteristics of liver cancer stem cells.

Increasing evidence suggests that liver cancer stem cells (LCSCs) are the cellular determinants that promote tumor recurrence and metastases. Aberrantly expressed miRNAs were identified in LCSCs and found to play a significant role in modulating biological characteristics of LCSCs. In this study, we implemented miRNA microarrays in CD133+ LCSCs and found miR-101 expression was downregulated.

Bile acids, lipid and purine metabolism involved in hepatotoxicity of first-line anti-tuberculosis drugs.

Objectives: Rifampin (RIF), isoniazid (INH) and pyrazinamide (PZA) are essential components of the short-term first-line anti-tuberculosis (anti-TB) chemotherapy regimen and can cause hepatotoxicity. However, the mechanism of anti-TB drug-induced hepatotoxicity (ATDH) is currently unclear. We investigate the relevant contributions to liver injury and the pathway of the above-mentioned drugs administered alone or in combination.
