Hepatocyte-Specific HuR Protects Against Acetaminophen-Induced Liver Injury in Mice.

Acetaminophen (APAP) overdose is a major cause of drug-induced liver injury (DILI) in many countries. Hepatocyte proliferation, autophagy and antioxidant capacity are crucial to the prognosis of APAP-induced liver injury, but the underlying mechanisms are not fully understood. Here, we found that human antigen R (HuR) protein expression was markedly increased in the model of APAP-induced liver injury, and conditional hepatocyte-specific HuR knockout aggravated APAP-induced liver injury in mice.

The Effectiveness of Cardiac Rehabilitation Programs in Improving Cardiovascular Outcomes: Systematic Review and Meta-Analysis.

Cardiovascular diseases (CVDs) are some of the most common conditions and the major contributors to death and disability globally, hence the need for proper secondary prevention interventions. Cardiac rehabilitation (CR) programs have been recognized as an essential component in the treatment of CVDs with the goal of decreasing the risk of new cardiovascular events and improving the quality of life. This systematic review and meta-analysis sought to determine the impact of CR as a form of CVD treatment on mortality, morbidity, functional capacity, and quality of life amongst the patient population.

This study aimed to assess the effectiveness of various forms of physical activity in reducing CVD risk factors among adults.

TNF compromises intestinal bile-acid tolerance dictating colitis progression and limited infliximab response.

The intestine constantly encounters and adapts to the external environment shaped by diverse dietary nutrients. However, whether and how gut adaptability to dietary challenges is compromised in ulcerative colitis is incompletely understood. Here, we show that a transient high-fat diet exacerbates colitis owing to inflammation-compromised bile acid tolerance.

Efficacy of Combination Therapies for Autoimmune Hepatitis: A Systematic Review and Meta-Analysis.

Autoimmune hepatitis (AIH) is a hepatocellular disorder thought to be caused by an immune system that cannot tolerate autoantigens specific to hepatocytes. This study aims to evaluate the efficacy of using corticosteroids (prednisolone and azathioprine) as a combination therapy in treating AIH. This study aims to synthesize and analyze existing evidence to inform clinical practices concerning the overall clinical efficacy of this treatment approach in managing AIH.

Enhanced Apc adenoma formation after epithelial CUL4B deletion by recruitment of myeloid-derived suppressor cells.

Colorectal cancer (CRC) stands as a prevalent malignancy globally. A pivotal event in CRC pathogenesis involves the loss-of-function mutation in the APC gene, leading to the formation of benign polyps. Despite the well-established role of APC, the contribution of CUL4B to CRC initiation in the pre-tumorous stage remains poorly understood.

Diffusion-tensor-imaging 1-year-old and 2-year-old infant brain atlases with comprehensive gray and white matter labels.

Molecular Determinant Underlying Selective Coupling of Primary G-Protein by Class A GPCRs.

G-protein-coupled receptors (GPCRs) transmit downstream signals predominantly via G-protein pathways. However, the conformational basis of selective coupling of primary G-protein remains elusive. Histamine receptors HR and HR couple with G- or G-proteins respectively.

GPR97 deficiency suppresses Wnt/β-catenin signaling in hypertensive nephropathy.

Accumulating evidence shows that renal fibrosis plays a key role in the development of hypertensive nephropathy (HTN). Therefore, a better understanding of the underlying mechanism of renal fibrosis regulation in HTN would be critical for designing rational strategies for therapeutic interventions. In this study, we revealed that GPR97, a novel identified adhesion G coupled receptor, plays an important role in the regulation of Wnt/β-catenin signaling, which is the crucial driver of renal fibrosis in HTN.

The role of vitamin D through SphK1/S1P in the regulation of MS progression.

Sphingosine-1-phosphate (S1P) is biologically active lipid, leading to neuroinflammation and macrophage invasion in central nervous system, plays an important role in the development of multiple sclerosis (MS) model in experimental allergic encephalomyelitis (EAE) rats. Vitamin D is observed to be a key factor in regulating cell S1P levels. We detected vitamin D can alleviate the symptoms of EAE rats, but the exact mechanism is unclear.

Structural basis of amine odorant perception by a mammal olfactory receptor.

Odorants are detected as smell in the nasal epithelium of mammals by two G-protein-coupled receptor families, the odorant receptors and the trace amine-associated receptors (TAARs). TAARs emerged following the divergence of jawed and jawless fish, and comprise a large monophyletic family of receptors that recognize volatile amine odorants to elicit both intraspecific and interspecific innate behaviours such as attraction and aversion. Here we report cryo-electron microscopy structures of mouse TAAR9 (mTAAR9) and mTAAR9-G or mTAAR9-G trimers in complex with β-phenylethylamine, N,N-dimethylcyclohexylamine or spermidine.
