Article Abstract
The apolipoprotein B mRNA editing enzyme catalytic subunit 3G (APOBEC3G) converts cytosine to uracil in DNA/RNA. Its role in resisting viral invasion has been well documented. However, its expression pattern and potential function in AML remain unclear. In this study, we carried out a bioinformatics analysis and revealed that the expression of APOBEC3G was significantly upregulated in AML, and high expression of APOBEC3G was significantly associated with short overall survival (OS). APOBEC3G expression was especially increased in non-M3AML, and correlated with the unfavorable cytogenetic risks. Additionally, Cox regression analyses indicated APOBEC3G is a hazard factor that cannot be ignored for OS of AML patients. In molecular docking simulations, the natural product crotonoside was found to interact well with APOBEC3G. The expression of APOBEC3G is the highest in KG-1 cells, and the treatment with crotonoside can reduce the expression of APOBEC3G. Crotonoside can inhibit the viability of different AML cells in vitro, arrest KG-1 and MV-4-11 cells in the S phase of the cell cycle and affect the expression of cycle-related proteins, and induce cell apoptosis. Therefore, APOBEC3G could be a potential drug target of crotonoside, and crotonoside can be considered as a lead compound for APOBEC3G inhibition in non-M3 AML.

The APOBEC cytidine/deoxycytidine deaminase family of enzymes has 11 members in humans. These enzymes carry out essential developmental, metabolic, and immunological functions through the deamination of cytosine to form uracil in RNA or single-stranded DNA. The known physiological functions relate to lipid absorption (APOBEC1), immunoglobulin gene diversification (AID), virus restriction (APOBEC3A-H, excluding E), and muscle differentiation (APOBEC2).

Objectives: The current research focuses on a systematic analysis of the expression patterns of the apolipoprotein B editing complex 3 () gene family in clear cell renal cell carcinoma (ccRCC) and their impact on disease progression, prognosis, and somatic gene mutations associated with ccRCC.
Methods: A differential expression analysis was performed using the R "limma" package, while a survival analysis was performed using Kaplan-Meier and log-rank tests. A Gene Set Enrichment Analysis performed by the R "clusterProfiler" package compared the high- and low-expression groups.

Objective: This study investigated the key genes shared between Psoriatic arthritis (PSA) and aging.
Methods: By integrating and analyzing single-cell RNA sequencing data from the synovial fluid of PsA patients, peripheral blood of senescent patients, and the normal population, the subpopulation of cells that were jointly upregulated in both was obtained as the core cellular subpopulation. We analyzed the proposed chronology of this core cellular subpopulations and the function of cellular communication, screened the differentially expressed genes in the core cellular subpopulations compared with other categories, analyzed the causal relationship between the differentially expressed genes and PsA by Mendelian randomization and analyzed the enriched pathways of key genes.

About 296 million people worldwide are living with chronic hepatitis B viral (HBV) infection, and outcomes to end-stage liver diseases are potentiated by alcohol. HBV replicates in hepatocytes, but other liver non-parenchymal cells can sense the virus. In this study, we aimed to investigate the regulatory effects of macrophages on HBV marker and interferon-stimulated genes (ISGs) expressions in hepatocytes.
