| Popis | Cancer cells are known to reprogram their metabolism to adapt to adverse conditions dictated by tumor growth and microenvironment. A subtype of cancer cells with stem-like properties, known as cancer stem cells (CSC), is thought to be responsible for tumor recurrence. In this study, we demonstrated that CSC and chemoresistant cells derived from triple negative breast cancer cells display an enrichment of up-and downregulated proteins from metabolic pathways that suggests their dependence on mitochondria for survival. Here, we selected antibiotics, in particular - linezolid, inhibiting translation of mitoribosomes and inducing mitochondrial dysfunction. We provided the first in vivo evidence demonstrating that linezolid suppressed tumor growth rate, accompanied by increased autophagy. In addition, our results revealed that bactericidal antibiotics used in combination with autophagy blocker decrease tumor growth. This study puts mitochondria in a spotlight for cancer therapy and places antibiotics as effective agents for eliminating CSC and resistant cells. |
