IL6 Derived from Macrophages under Intermittent Hypoxia Exacerbates NAFLD by Promoting Ferroptosis via MARCH3-Led Ubiquitylation of GPX4.

Obstructive sleep apnea (OSA) is a common sleep disorder characterized by intermittent hypoxia (IH) and is associated with the occurrence and development of nonalcoholic fatty liver disease (NAFLD). However, the specific mechanism by which OSA induces NAFLD remains unclear. Therefore, effective interventions are lacking.

Tailoring linear and nonlinear plasmons of metal/MoS/metal nanostructures.

We investigated the linear and nonlinear response of the localized surface plasmons (LSPs) and surface plasmon polaritons (SPPs) in metal and MoS nanostructures. The results show that the response of LSPs and SPPs has an important influence on the energy exchange. SPPs with unique non-radiative characteristics can be used as energy recovery tanks to reuse the radiated energy of LSPs and promote the production of hot carriers.

Peroxisomal ERK mediates Akh/glucagon action and glycemic control.

The enhanced response of glucagon and its Drosophila homolog, adipokinetic hormone (Akh), leads to high-caloric-diet-induced hyperglycemia across species. While previous studies have characterized regulatory components transducing linear Akh signaling promoting carbohydrate production, the spatial elucidation of Akh action at the organelle level still remains largely unclear. In this study, we find that Akh phosphorylates extracellular signal-regulated kinase (ERK) and translocates it to peroxisome via calcium/calmodulin-dependent protein kinase II (CaMKII) cascade to increase carbohydrate production in the fat body, leading to hyperglycemia.

and were correlated with adipose tissue macrophage infiltration and involved in obstructive sleep apnea related metabolic dysregulation: Evidence from bioinformatics analysis.

Both obesity and obstructive sleep apnea (OSA) can lead to metabolic dysregulation and systemic inflammation. Similar to obesity, increasing evidence has revealed that immune infiltration in the visceral adipose tissue (VAT) is associated with obstructive sleep apnea-related morbidity. However, the pathological changes and potential molecular mechanisms in visceral adipose tissue of obstructive sleep apnea patients need to be further studied.

Serum Transferrin Level Is Associated with the Severity of Obstructive Sleep Apnea Independently of Obesity: A Propensity Score-Match Observational Study.

Introduction: Dysregulation of iron metabolism is closely associated with the development of obesity and obstructive sleep apnea (OSA), but little is known about the relationship between serum transferrin (TF) level and OSA severity. We aimed to verify this relationship and fit into account for obesity-related confounders among bariatric candidates.

Methods: We compared data retrospectively collected in 270 bariatric candidates.

Acetylation of lactate dehydrogenase B drives NAFLD progression by impairing lactate clearance.

Background & Aims: Lactate has recently been reported to accumulate in the livers of patients progressing from simple steatosis to non-alcoholic steatohepatitis (NASH). However, the underlying mechanism(s) of lactate accumulation and the role of lactate in the progression of non-alcoholic fatty liver disease (NAFLD) are essentially unknown.

Methods: We compared the acetylome in liver samples taken from healthy individuals, patients with simple steatosis and patients with NASH to identify potential targets of acetylation with a role in lactate metabolism.

Casein kinase 2 inhibitor CX-4945 elicits an anti-Warburg effects through the downregulation of TAp73 and inhibits gastric tumorigenesis.

Casein kinase 2 (CK2) has become a potential therapeutic target in gastric cancer; however, the underlying mechanism remains incompletely understood. TAp73, a structural homolog of the tumor suppressor p53, acts as a critical regulator of the Warburg effect. Recent study reveals that aberrant CK2 signaling is able to inhibit TAp73 function.

Tumoricidal activities of pterostilbene depend upon destabilizing the MTA1-NuRD complex and enhancing P53 acetylation in hepatocellular carcinoma.

The present study aimed to assess the tumoricidal effect of metastasis-associated protein 1 (MTA1) induced by pterostilbene (PTER) in hepatocellular carcinoma (HCC). The SMMC-7721 hepatoma cell line was treated with PTER. Following treatment, the mRNA transcript abundance of MTA1 was measured using quantitative polymerase chain reaction.

Genetic polymorphism of interleukin-6 influences susceptibility to HBV-related hepatocellular carcinoma in a male Chinese Han population.

As a multifunctional cytokine, interleukin-6 (IL-6) plays a key role in chronic inflammation as well as tumor growth and progression of hepatitis B virus (HBV) infection. Recent studies have implicated that single nucleotide polymorphism (SNP) -572C>G (rs1800796) located within the promoter region of IL-6 gene was associated with susceptibility to several diseases. Here, a case-control study was undertaken to investigate the association between this polymorphism and HBV-related hepatocellular carcinoma (HCC) susceptibility in a Chinese Han population.

Rather than Rs1800796 polymorphism, expression of interleukin-6 is associated with disease progression of chronic HBV infection in a Chinese Han population.

Interleukin-6 plays an important role in chronic inflammation as well as tumor growth and progression. Here, a case-control study was undertaken to investigate the association of rs1800796 polymorphism of IL-6 gene and serum levels with disease progression of chronic HBV infection. Rs1800796 polymorphism was genotyped in 641 Chinese Han patients with chronic HBV infection, including 23 IT, 25 IC, 292 CHB, 153 LC, and 148 HCC patients and 265 healthy controls.

Inhibition of hepatocelluar carcinoma MAT2A and MAT2beta gene expressions by single and dual small interfering RNA.

RNA interference (RNAi) has been successfully applied in suppression of hepatic cancer genes. In hepatocelluar carcinoma cell, one methionine adenosyltransferase (MAT) isozyme, MATII was found to have two catalytic subunits which were encoded by MAT2A and MAT2beta respectively. During tumorigeness of hepatocelluar carcinoma, expressions of the two genes were discovered to be increased combining with a switch of MAT (form MATI to MATII), To figure out the role played by MATII in hepatic cancer, In this study, for the first time we established a dual small interfering RNA (siRNA) expression system, which could simultaneously express two different siRNA molecules specifically targeting two genes.

Treatment of upper gastrointestinal fistula and leakage with personal stage nutrition support.

Aim: To investigate the feasibility of treatment for upper gastrointestinal fistula and leakage with personal stage nutrition support.

Methods: Forty-three patients with upper gastrointestinal fistula and leakage were randomly divided into two groups. Patients in group A were treated with personal stage nutrition support and patients in group B were treated with total parental nutrition (TPN) in combination with operation.

Lentivirus mediated shRNA interference targeting MAT2B induces growth-inhibition and apoptosis in hepatocelluar carcinoma.

Aim: To investigate the effects of lentivirus vector mediated short hairpin RNA interference targeting methionine adenosyltransferase 2beta gene (LV-shMAT2B) on hepatocelluar carcinoma (HCC) cells.

Methods: We constructed four plasmids of RNA interference targeting the MAT2B gene. After LV-shMAT2B was transfected with L-02 cells and two kinds of HCC cells, cell viability and proliferation were measured with MTT and [3H]thymidine assays respectively.

Expression of angiopoietin-2 is correlated with vascularization and tumor size in human colorectal adenocarcinoma.

Angiopoietins are endothelial growth factors, which play crucial roles in normal vascular development and tumor angiogenesis. We examined the expression profiles of angiopoietin-1 (Ang-1), angiopoietin-2 (Ang-2), vascular endothelial growth factor (VEGF), and Tie-2, a receptor for Ang-1 and Ang-2, in both colorectal adenocarcinoma and adjacent normal tissues, as judged by histology, in order to elucidate their relationships with microvascular density (MVD) and clinicopathologic properties. Higher MVD was associated with a lower degree of differentiation of colorectal adenocarcinoma.
