Article Synopsis
  • 8-oxoguanine (8-oxoG) is a DNA lesion caused by reactive oxygen species that leads to genetic instability, and it's recognized by the repair protein OGG1.
  • OGG1 plays a dual role in base excision repair and regulates gene expression, particularly during the activation of fibroblasts in lung fibrosis.
  • Increasing OGG1 levels during fibroblast activation enhances pro-fibrotic gene expression in response to bleomycin, suggesting that targeting OGG1 could be a viable therapeutic strategy for treating Idiopathic Pulmonary Fibrosis (IPF).

Department of Orthodontics, School and Hospital of Stomatology, China Medical University, Liaoning Provincial Key Laboratory of Oral Diseases, Shenyang, 110002, China. Electronic address:

Mitochondrial dysfunction is implied as a crucial factor in age-related chronic kidney disease. It is confirmed that Gli-like transcription factor 1 (GLIS1) is involved in age-related renal fibrosis, however, the correlation between mitochondrial disturbances and GLIS1-driven kidney aging are not clearly clarified. Thus, we investigated the regulatory mechanism of GLIS1 in the homeostasis of mitochondrial quality control both in vivo and in vitro.

Circular RNA (circRNA) molecules are noncoding RNAs with ring-like structures formed by covalent bonds and are characterized by no 5caps or polyadenylated tails. Increasing evidence shows that circRNAs may play an important role in tumorigenesis and cancer metastasis. Circ-SHPRH originates from exons 26-29 of the gene, and it is closely associated with human cancers.

Article Synopsis
  • The study evaluated the effectiveness and safety of laparoscopic radiofrequency ablation (LRFA) versus percutaneous radiofrequency ablation (PRFA) for treating hepatitis B virus-related liver cancer (HCC).
  • It involved 109 patients and found no significant difference in overall survival rates between the two methods, but LRFA demonstrated a higher disease-free survival rate than PRFA.
  • Both methods had similar complication rates, with common issues including ascites, pleural effusion, and fever, suggesting that LRFA may be preferable for certain liver cancer treatments.
