Liver cancer is the third leading cause of cancer‑related mortality globally, with increasing morbidity and mortality rates. Sorafenib, a multi‑kinase inhibitor, is an effective first‑line therapy for late‑stage liver cancer. However, its effectiveness is hindered by low responsiveness, high drug resistance and significant side effects. The progression and metastasis of liver cancer are associated with alterations in mitochondrial metabolism, including mitochondrial stress responses and defects in oxidative phosphorylation, which are involved in the increased production of reactive oxygen species. Targeting mitochondrial biogenesis and bioenergetics presentsa promising therapeutic strategy. Bioinformatics analysis (inte‑ grated analysis of The Cancer Genome Atlas, mitochondrial genomes, liver cancer mouse models, and bioinformatics tools) revealed that the expression of single‑stranded DNA‑binding protein 1 (SSBP1) was significantly elevated in liver cancer. In addition, MTT and colony formation assays showed that increased SSBP1 expression notably enhanced cell prolifera‑ tion, while wound healing and Transwell assays demonstrated enhanced metastasis. Furthermore, flow cytometry, qPCR,  \nCorrespondence to: Dr Zihan Wang or Professor Lu Zhu, Department of Pharmacology, State Key Laboratory of Experimental Hematology, Tianjin Key Laboratory of Inflammatory Biology, The Province and Ministry Co‑Sponsored Collaborative Innovation Center for Medical Epigenetics, National Health Commission Key Laboratory of Hormones and Development, Chu Hsien‑I Memorial Hospital and Tianjin Institute of Endocrinology, School of Basic Medical Sciences, Tianjin Medical University, 22 Qixiangtai Road, Heping, Tianjin 300070, P.R.

Clinical correla‑ tion analysis demonstrated that higher SSBP1 expression was associated with poorer prognosis in patients with liver cancer. In summary, the present study identified SSBP1 as a potential driver of tumor growth and a promising prognostic biomarker and therapeutic target in liver cancer, thus providing novel insight for improving patient outcomes.  \nIntroduction  \nLiver cancer, the third leading cause of cancer‑associated death worldwide (1), with an estimated 865,269 new liver cancer cases and 757,948 related deaths occurring worldwide in 2022, poses a significant public health challenge, especially in China, where the 5‑year survival rate was 12.1% from 1990 to 2021 (2) .
