Autophagy is a critical cellular process involved in the degradation and recycling of cytoplasmic components, playing a dual role in cancer by either promoting cell survival or facilitating cell death. In glioblastoma (GB), autophagy has been implicated in resistance to the chemotherapeutic agent Temozolomide (TMZ). This study presents a novel method to accurately measure autophagy flux in TMZ-resistant glioblastoma cells, combining advanced imaging techniques with biochemical assays. By quantifying key autophagy markers such as LC3-II and SQSTM1, our approach provides detailed insights into the dynamic processes of autophagosome formation and clearance under therapeutic stress. This method not only advances our understanding of autophagy in GB chemoresistance but also has significant implications for the development of autophagy-targeted therapies. The ability to monitor and manipulate autophagy flux in real-time offers a promising avenue for monitoring and understnading TMZ resistance and improving patient outcomes in glioblastoma treatment.
