Mitochondrial Dysfunction in Hepatocellular Carcinoma: Insights into the Diagnostic and Therapeutic Implications

Hepatocellular carcinoma (HCC) presents a significant problem that necessitates a greater understanding of its underlying molecular complexity in order to improve diagnostics and therapies. Recent studies have shed light on the critical role that mitochondrial dysfunction plays in the development and course of HCC. Once thought to be primarily involved in the synthesis of cellular energy, mitochondria are now known to be key participants in the regulation of a variety of cellular functions that go beyond bioenergetics. The purpose of this review is to elucidate the diagnostic and therapeutic implications of mitochondrial dysfunction in HCC by synthesising ideas from conventional and contemporary scientific literature. Within diagnostics, the discovery of mitochondrial biomarkers such as mutations in mitochondrial DNA and abnormalities in respiratory chain complex activities provides a state-of-the-art viewpoint for the timely identification and accurate description of HCC. In addition, non-invasive imaging methods that focus on mitochondrial function offer prospective means of improving clinical diagnostic accuracy. Moving on to treatment, a growing area of study investigates how mitochondria-targeted therapies might be used to treat HCC. Novel substances and repurposed medications with the potential to induce selective apoptosis in cancer cells, reduce oxidative stress, and restore mitochondrial homeostasis are highly promising. In the fight against hepatocellular carcinoma, an understanding of the complex interactions between mitochondrial dysfunction and HCC opens new diagnostic opportunities and paves the way for individualised treatment plans.
