Prohibitins in cancer: Multifaceted regulators of mitochondrial homeostasis, oncogenic signaling, tumor microenvironment, and therapeutic resistance. (PubMed, Cancer Genet)
We summarize the cancer-type-specific expression patterns of PHB1/2 and their prognostic value, and provide an in-depth analysis of the mechanisms by which PHBs confer resistance to platinum drugs, paclitaxel, PARP inhibitors, and radiotherapy through stabilization of anti-apoptotic proteins, mitochondrial protection, and maintenance of cancer stem cell properties. Finally, we catalogue the expanding armamentarium of PHB-targeted interventions, including small-molecule ligands, stapled peptides, DNA aptamers, and siRNA delivery platforms, and discuss the challenges and opportunities for clinical translation. By integrating molecular mechanisms with translational perspectives, this review highlights PHBs as unique regulatory nodes at the intersection of metabolism, signaling, and immunity, and advocates for precision strategies that exploit context-specific PHB functions to overcome therapy resistance and improve cancer treatment.
