Modulatory effects of CNNM4 on protein- l -isoaspartyl- O -methyltransferase repair function during alcohol-induced hepatic damage.

Background And Aims: Alcohol-associated liver disease (ALD) is a leading cause of liver-related mortality worldwide, with limited treatment options beyond abstinence and liver transplantation. Chronic alcohol consumption has been linked to magnesium (Mg 2+ ) deficiency, which can influence liver disease progression. The mechanisms underlying Mg 2+ homeostasis dysregulation in ALD remain elusive.

Nicotinamide Riboside and CD38: Covalent Inhibition and Live-Cell Labeling.

Nicotinamide adenine dinucleotide (NAD) is required for a myriad of metabolic, signaling, and post-translational events in cells. Its levels in tissues and organs are closely associated with health conditions. The homeostasis of NAD is regulated by biosynthetic pathways and consuming enzymes.

Discovery of PARP1-Sparing Inhibitors for Protein ADP-Ribosylation.

Poly-ADP-ribose polymerases (PARPs) that catalyze cellular ADP-ribosylation play important roles in human health. PARP inhibitors have found success in the clinic for cancer treatment. However, isoform-specific inhibitors are needed for improved safety.

The value of serum Mac-2 binding protein glycosylation isomer in the diagnosis of liver fibrosis: a systematic review and meta-analysis.

Background: The early detection and intervention of liver fibrosis (LF) in patients with chronic liver disease is critical to their management. The accuracy of serum Mac-2 binding protein glycosylation isomer (M2BPGi) in the diagnosis of LF remains controversial. This study aimed to comprehensively assess the value of serum M2BPGi in diagnosing LF.

The long-term impact of post-cholecystectomy major bile duct injury on liver stiffness.

Introduction: Iatrogenic bile duct injuries (BDI) are a devastating complication. Long-term impact of corrective hepaticojejunostomy (HJ) for such injuries on post -surgery liver stiffness is lacking. Hence the aim of this study was to explore the extent of hepatic fibrosis in a cohort of patients with Strasberg E bile duct injuries who underwent HJ after a minimum follow-up of six months.

An NAD with Dually Modified Adenine for Labeling ADP-Ribosylation-Specific Proteins.

Protein adenosine diphosphate (ADP)-ribosylation participates in various pivotal cellular events. Its readers and erasers play key roles in modulating ADP-ribosylation-based signaling pathways. Unambiguous assignments of readers and erasers to individual ADP-ribosylated proteins provide insightful knowledge on ADP-ribosylation biology and require the development of tools and technologies for this goal.

Tenofovir and Hepatitis B Virus Transmission During Pregnancy: A Randomized Clinical Trial.

Importance: Standard care for preventing mother-to-child transmission (MTCT) of hepatitis B virus (HBV) in highly viremic mothers consists of maternal antiviral prophylaxis beginning at gestational week 28 combined with an HBV vaccine series and HBV immune globulin (HBIG) at birth. However, HBIG is unavailable in some resource-limited areas.

Objective: To determine whether initiating tenofovir disoproxil fumarate (TDF) at gestational week 16 combined with HBV vaccinations for infants is noninferior to the standard care of TDF at gestational week 28 combined with HBV vaccinations and HBIG for infants in preventing MTCT in mothers with HBV and high levels of viremia.

NAFLD No More: A Review of Current Guidelines in the Diagnosis and Evaluation of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD).

Purpose Of Review: Provide a concise update on metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD), as well as a practical approach to screening and initial evaluation.

Recent Findings: Nomenclature changes have placed a greater focus on cardiometabolic risk factors in the definition of MASLD. Screening for MASLD is by stepwise noninvasive serum and imaging tests which can identify patients at risk for advanced fibrosis and liver-related complications.

Anti-integrin αvβ6 Autoantibodies are Increased in Primary Sclerosing Cholangitis Patients With Concomitant Inflammatory Bowel Disease and Correlate With Liver Disease Severity.

Senescence-related genes are associated with the immunopathology signature of American Tegumentary Leishmaniasis lesions and may predict progression to mucosal leishmaniasis.

The American Tegumentary Leishmaniasis (ATL) is caused by protozoans of the genus Leishmania and varies from mild localized cutaneous leishmaniasis (LCL) form to more severe manifestations such as the diffuse cutaneous leishmaniasis (DCL) form and the mucosal leishmaniasis (ML) form. Previously, we demonstrated the accumulation of senescent cells in skin lesions of patients with LCL. Moreover, lesional transcriptomic analyses revealed a robust co-induction of senescence and pro-inflammatory gene signatures, highlighting the critical role of senescent T cells in orchestrating pathology.
