- Hepatitis B virus (HBV) is a major global health concern linked to liver disease and cancer, with research focusing on genetic factors that affect its evolution.
- Recent studies highlighted the ECM1 gene, specifically two polymorphisms (rs3834087 and rs3754217), which may influence HBV pathogenesis, particularly in an African cohort analyzed in this research.
- The study found that the heterozygous genotype of rs3754217 appears to protect against chronic hepatitis, suggesting that certain genetic variations may impact the severity of the disease in infected individuals.
Article Abstract
Hepatitis B virus (HBV) is a significant cause of liver disease and cancer worldwide. Understanding the genetic factors influencing HBV evolution is crucial for developing effective prevention and treatment strategies. Host genetic and environmental factors particularly influence the evolution of this infection. Recent studies have implicated the ECM1 gene in HBV pathogenesis, mainly two specific polymorphisms (rs3834087 and rs3754217). In an African cohort, we comprehensively analyzed these ECM1 gene polymorphisms and their association with HBV evolution.In this case-control analysis, 167 samples, consisting of 59 controls and 108 cases, were examined. The cases included 50 patients with Chronic Hepatitis B(CHB), 16 with cirrhosis, and 42 with hepatocellular carcinoma (HCC). Genomic DNA extraction was executed using INVITROGEN and FAVORGEN kits. Genotyping of rs3834087 and rs3754217 polymorphisms in the ECM1 gene was accomplished via real-time PCR on the QuantStudioTM 5 Real-Time instrument, followed by allelic discrimination using TaqMan Genotyper Software. Data was interpreted using SPSS version 20 and Epi info version 7.5.2.0. Odds ratios (OR), confidence intervals (CI), and p-values were derived for risk and significance evaluation.In our study, the heterozygous genotype (GT) of rs3754217 could confer protection to controls against the onset of chronic hepatitis in the event of infection (OR=0.05; CI=0.006-0.46; p=0.002). In addition, carriage of mutated alleles of the two (2) polymorphisms was associated with the course of infection and may influence the appearance of severe forms at certain stages of the disease.Our study is the first to assess the association between polymorphisms (rs3834087 and rs3754217) in the ECM1 gene and the course of HBV infection in Burkina Faso. It showed that combining specific genotypes of the two (2) polymorphisms would be associated with protection against chronic hepatitis.

Background: Retroperitoneal liposarcoma (RLPS) is a mesenchymal malignant tumor characterized by different degrees of adipocytic differentiation. Well-differentiated liposarcoma (WDLPS) and dedifferentiated liposarcoma (DDLPS) are two of the most common subtypes of RLPS, exhibiting clear differences in biological behaviors and clinical prognosis. The metabolic features and genomic characteristics remain unclear.

Article Synopsis
- The study investigates how T follicular helper cells and the cytokine IL-21 contribute to hypoxia-induced pulmonary hypertension (HPH), a condition that can lead to serious heart problems.
- Using mouse models, the research found that mice lacking IL-21 or with reduced T cells showed less severe pulmonary hypertension, suggesting that IL-21 plays a crucial role in the disease's progression.
- The findings revealed that chronic exposure to hypoxia increases germinal center B cell activity and promotes a shift in macrophages towards a phenotype that exacerbates vascular remodeling, showcasing potential targets for future therapies.

Purpose: Leiomyosarcoma (LMS) is an aggressive mesenchymal malignant tumor with poor therapeutic options, but the molecular mechanisms underlying LMS remain largely unknown. Increasing evidence indicates that transient receptor potential vanilloid 4 (TRPV4) levels are closely related to the advancement of various malignant tumors through diverse molecular mechanisms. However, the roles and regulatory mechanisms of TRPV4 in LMS progression remain unclear.
