G6PD deficiency triggers dopamine loss and the initiation of Parkinson's disease pathogenesis.

Loss of dopaminergic neurons in Parkinson's disease (PD) is preceded by loss of synaptic dopamine (DA) and accumulation of proteinaceous aggregates. Linking these deficits is critical to restoring DA signaling in PD. Using murine and human pluripotent stem cell (hPSC) models of PD coupled with human postmortem tissue, we show that accumulation of α-syn micro-aggregates impairs metabolic flux through the pentose phosphate pathway (PPP).

Impact of racial, ethnic, and socioeconomic disparities on presentation and survival of HCC: A multicenter study.

Background: Racial and ethnic disparities have been reported for HCC prognosis, although few studies fully account for clinically important factors and social determinants of health, including neighborhood socioeconomic status.

Methods: We conducted a retrospective multicenter cohort study of patients newly diagnosed with HCC from January 2010 through August 2018 at 4 large health systems in the United States. We used multivariable logistic regression and cause-specific Cox proportional hazard models to identify factors associated with early-stage HCC presentation and overall survival.

Unveiling Disparities: Analyzing Hispanic Inclusion in Liver Cancer Research Databases in the United States.

Primary liver cancer, including hepatocellular carcinoma and intrahepatic cholangiocarcinoma was the sixth leading cause of cancer death in the United States in 2023. Hispanic people constitute approximately 19% of the nation's total population according to the US Census. Hispanic patients have the highest relative incidence rates of liver cancer compared to non-Hispanic Whites and non-Hispanic Blacks, a disparity frequently overlooked in cancer research.

Development of a single-domain antibody to target a G-quadruplex located on the hepatitis B virus covalently closed circular DNA genome.

To achieve a virological cure for hepatitis B virus (HBV), innovative strategies are required to target the covalently closed circular DNA (cccDNA) genome. Guanine-quadruplexes (G4s) are a secondary structure that can be adopted by DNA and play a significant role in regulating viral replication, transcription, and translation. Antibody-based probes and small molecules have been developed to study the role of G4s in the context of the human genome, but none have been specifically made to target G4s in viral infection.

Low Health Literacy, Lack of Knowledge, and Self-Control Hinder Healthy Lifestyles in Diverse Patients with Steatotic Liver Disease.

Introduction: In parallel with the obesity and diabetes epidemics, steatotic liver disease (SLD) has emerged as a major global public health concern. The mainstay of therapy is counseling on weight loss and increased exercise. However, such lifestyle modifications infrequently lead to success.
