ACLY-β-catenin axis modulates hepatoblastoma cell proliferation

Nur77 inhibition of β-catenin expression mediates Hepatoblastoma progression and enhances cisplatin's therapeutic effect

Hepatoblastoma (HB) is the most common malignant tumor in children under 5 years old, but its pathogenesis remains unclear. Nur77 has been reported to be an important regulator for cancer progression in various cancer types. This study found that Nur77 was downregulated in HB tumors, compared with paracancer tissue. Knockout or overexpression of Nur77 in HB tumor cell line HepG2 and HuH6 could significantly enhance or inhibit the proliferation, migration and invasion of tumor cells both in vitro and in vivo. Further studies illustrated that Nur77 regulated the proliferation of tumor cells by affecting the expression of β-catenin. Nur77 agonist Csn-B effectively enhanced the therapeutic effect of cisplatin on HB tumors both in vitro and in vivo. This study confirms that Nur77 may act as an oncogene in HB tumors and mediate the progression of HB by inhibiting the expression of β-catenin, which provides a new targeted therapy for the clinical treatment of HB patients; meanwhile, the combination of Nur77 agonist and cisplatin treatment may improve the chemotherapeutic efficacy of HB patients, which provides a new idea for the improvement of the clinical prognosis of HB patients.

Digital medicine and minimally invasive surgery in pediatric hepatoblastoma: An update

Hepatoblastoma (HB) is the most common liver malignancy in children, accounting for approximately 60 % of liver tumors in this population. However, the exact cause of HB remains unclear. The combination of surgery and neoadjuvant chemotherapy has significantly improved the overall survival rate of children with HB, increasing it from 40 % in the past to over 70 %. The concept of precise hepatectomy, which aims to achieve the best rehabilitation outcomes with minimal trauma and maximum liver protection, has been widely accepted by hepatobiliary surgeons. This article provides a comprehensive review of the recent advancements in surgical treatment of HB, focusing on digital surgery and minimally invasive techniques.
