Similar analyses were repeated, but this time using the ratio of ADAMTS2 on COL1A1 expression to take into account potential biases due to the involvement of ADAMTS2 in collagen fibril formation. Remarkably, these data indicate that patients with a high ADAMTS2/COL1A1 ratio exhibit an improved overall survival rate, suggesting that ADAMTS2 may inhibit cancer progression by a mechanism independent of collagen accumulation. This hypothesis was evaluated in vivo using ADAMTS2-KO mice and different tumor models characterized by the absence or presence of tumor collagen accumulation, as in MMTV-PyMT mice which develop spontaneous desmoplastic mammary tumors. In all the models, the growth of primary tumors was strongly increased in ADAMTS2-KO mice versus their wild type counterparts, confirming that ADAMTS2 displays anti-tumor properties. In stark contrast, the spread of lung metastases from mammary tumors was virtually prevented in ADAMTS2-KO mice, showing a dual role of ADAMTS2, either beneficial or detrimental, at different stages of cancer progression.

This persistent cccDNA, often referred to as an \"invisible bullet\", plays a pivotal role not only in the horizontal transmission of HBV but also within the context of hepatocellular carcinoma (HCC). Growing evidence reveals that noncoding RNAs (ncRNAs) are deeply involved in cancer progression, as well as the HBV life cycle and related pathogenesis, including liver inflammation, fibrosis, and HCC. This involvement occurs through various mechanisms, as ncRNAs regulate gene transcription, act as miRNA sponges, modulate signaling pathways, and influence downstream effects. These functions depend on the proper formation of RNA structures, which are critical for maintaining the biological activity of ncRNAs. The structure of RNAs appears to play a pivotal role in their functional capacity. Moreover, both ncRNAs and viral nucleotides contribute to G-quadruplex structure formation, which is essential for the HBV life cycle and cancer progression.

Hepatitis B virus X (HBx) gene was sequenced from entecavir-treated patients who developed hepatocellular carcinoma (HCC). Functional assays were conducted using Transwell assays, MTT assays, and xenograft model.</p><p><strong>Results: </strong>Suboptimal response was found to be a significant independent predictor of HCC development. Five of the six patients who developed HCC in the suboptimal response period were found to have HBx mutations (HBx-L100 insertion, HBx-G32R/K130M, HBx-Q87G/k130M/C143R, HBx-L123S, and HBx-H94Y/K130M). Overexpression of the HBx-H94Y/K130M mutation in HepG2.2.15 cells showed significantly increased cccDNA accumulation and enhanced cell migration compared to controls and other HBx mutants. RNA-seq analysis identified RPL13AP25 as a direct target of HBx-H94Y/K130M. RPL13AP25 was highly expressed in HCC tissues, and its elevated expression was associated with poor overall survival and enhanced cell motility and cccDNA accumulation both in vitro and in vivo. Mechanistically, both HBx-H94Y/K130M and RPL13AP25 enhanced the hyperphosphorylation of eIF4EBP1, leading to its dissociation from eIF4E, which subsequently enhances protein synthesis and ultimately contributes to HCC.</p><p><strong>Conclusions: </strong>The HBx-H94Y/K130M mutant, selected during the period of suboptimal virological response, appears to promote cccDNA accumulation, likely through the upregulation of RPL13AP25, which contributed to HCC progression.</p>","PeriodicalId":9385,"journal":{"name":"Cancer Cell International","volume":"25 1","pages":"223"},"PeriodicalIF":5.3,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12182696/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
