Their unique properties, including drug resistance and metastatic potential, pose challenges for effective targeting. These cells exploit certain metabolic processes for their maintenance and survival. One of these processes is autophagy, which generally helps in energy homeostasis but when hijacked by CSCs can help maintain their stemness. Thus, it is often referred as an Achilles heel in CSCs, as certain cancers tend to depend on autophagy for survival. Autophagy, while crucial for maintaining stemness in cancer stem cells (CSCs), can also serve as a vulnerability in certain contexts, making it a complex target for therapy. Regulators of autophagy like AMPK (5′ adenosine monophosphate-activated protein kinase) also play a crucial role in maintaining CSCs stemness by helping CSCs in metabolic reprogramming in harsh environments. The purpose of this review is to elucidate the interplay between autophagy and AMPK in CSCs, highlighting the challenges in targeting autophagy and discussing therapeutic strategies to overcome these limitations. This review focuses on previous research on autophagy and its regulators in cancer biology, particularly in CSCs, addresses the remaining unanswered questions, and potential targets for therapy are also brought to attention.  \nKeywords: cancer stem cells; autophagy; AMPK  \n1. Introduction  \nCancer presently stands as the primary cause of premature death and a significant obstacle to global life expectancy, with projections indicating a further increase in its prevalence over the next five decades [1] . In late-stage malignancies, the chance of complete recovery decreases, resulting in reduced survival rates. Thus, quick discovery, diagnosis, and successful treatment are critical for patients’ full recovery and improved quality of life. Patients who have undergone chemotherapy or radiotherapy frequently encounter relapses, with CSCs being identified as one of the contributing factors. CSCs were initially characterized as a subset of cancer cells capable of self-renewal and differentiation into progenitor cancer cells. These cells typically remain dormant and can re-emerge under favorable conditions, contributing to disease recurrence.
