Background: Factors influencing health-related quality of life (HRQoL) and financial toxicity (FT) have been found to overlap, and the robust correlation between HRQoL and FT raises the possibility that FT mediates the relationships between the shared risk factors and HRQoL. However, empirical evidence supporting this hypothesis is limited.

Objective: This study aimed to explore whether FT mediates the relationships between HRQoL and its risk factors.

PRMT1-mediated methylation of ME2 promotes hepatocellular carcinoma growth by inhibiting ubiquitination.

Cell Death Dis

November 2024

Department of Nutrition and Food Hygiene, School of Public Health, Guizhou Medical University, 561113, Guiyang, Guizhou, P.R. China.

The mitochondrial malic enzyme 2 (ME2), which is frequently elevated during carcinogenesis and may be a target for cancer therapy, catalyzes the conversion of malate to pyruvate. The processes controlling ME2 activity, however, remain largely unclear. In this work, we show that human hepatocellular carcinoma (HCC) tissues contain high levels of ME2 and that the methylation of ME2 stimulates the growth and migration of HCC cells.

Dysregulation of R-loop homeostasis shapes the immunosuppressive microenvironment and induces malignant progression in melanoma.

Apoptosis

November 2024

Key Laboratory of Infectious Immune and Antibody Engineering of Guizhou Province, Engineering Research Center of Cellular Immunotherapy of Guizhou Province, Guizhou Medical University, Guiyang, China.

Dysregulated R-loop homeostasis leads to DNA replication stress and genomic instability, a major driver of cancer. However, the role of R-loops in melanoma development remains unclear. We established an R-loop scoring model based on a single-cell RNA sequencing dataset and evaluated the association between the R-loop score with the melanoma immune microenvironment and treatment response.

Article Synopsis
  • A phase 3 trial compared the effectiveness and safety of zuberitamab combined with CHOP chemotherapy (Hi-CHOP) against rituximab combined with CHOP (R-CHOP) in patients with untreated CD20-positive diffuse large B-cell lymphoma (DLBCL).
  • The trial involved 487 patients, with a primary focus on the objective response rate (ORR) after six treatment cycles, finding that Hi-CHOP achieved a similar ORR to R-CHOP while demonstrating a significantly higher complete response (CR) rate in some analyses.
  • Long-term follow-up indicated that Hi-CHOP patients experienced improved duration of response (DOR), progression-free survival (PFS), and overall survival

Article Synopsis
  • * It identifies a specific population of Ki67 proliferating regulatory T cells that express immunosuppressive markers, which correlates with treatment outcomes; higher levels were seen in patients who relapsed.
  • * The findings indicate that low baseline levels of these Ki67 Tregs can predict the effectiveness of immunotherapy, and similar results were confirmed in two other trials, suggesting a potential for personalized treatment strategies.

Introduction: Breast cancer (BC) is a prevailing malignancy among women, and its inconspicuous development contributes significantly to mortality. The RNA N6-methyladenosine (mA) modification represents an emerging mechanism for gene expression regulation, with the active involvement of the YTH N6-methyladenosine RNA binding protein 3 (YTHDF3) in tumor progression across multiple cancer types. Nonetheless, its precise function in breast cancer necessitates further investigation.

Department of Biology, College of Basic Medical Sciences, Guizhou Medical University, Guiyang, Guizhou, China. Electronic address:

Reovirus (Reo) has shown promising potential in specifically killing tumor cells, and offering new possibilities for ovarian cancer (OC) treatment. However, neutralizing antibodies in the ascites from OC patients greatly limit the further application of Reo. In this study, we employed cationic liposomes (Lipo) to deliver Reo, significantly enhancing its ability to enter OC cells and its effectiveness in killing these cells under ascitic conditions.

Article Synopsis
  • Pancreatic cancer is a serious disease that doesn’t show symptoms until it's very advanced, making it tough to treat, and surgery is currently the best method we have.
  • Researchers studied a protein called TAGLN2 to see if it could control other proteins that help pancreatic cancer cells grow and spread.
  • The study found that high levels of TAGLN2 in pancreatic cancer are linked to worse outcomes, and when they silenced another protein, ARPC5, it stopped TAGLN2 from making the cancer cells grow and spread.

Glycyrrhizic acid (GA) has effects on anti-hepatic fibrosis, anti-tumor and prevention from hepatocellular carcinoma (HCC) progression. Yet, the capacity of GA to ameliorate the advance of HCC pertinent to nonalcoholic fatty liver disease (NAFLD) remains to be clarified. We used the CCK-8 method to detect the optimal treatment concentration and time for L-02 cells, palmitic acid (PA)-induced L-02 cells and HepG2 cells, and selected 40 μM and 48 h to treat PA-induced L-02 cells and 60 μM for 24 h to treat HepG2 cells.
