Autophagy plays a complex role in cancer progression, serving as both a tumor suppressor and a promoter, depending on the context. In triple-negative breast cancer (TNBC), a particularly aggressive subtype with limited therapeutic options, autophagy inhibition has emerged as a promising strategy to enhance the efficacy of chemotherapy. This study investigates the synergistic effects of autophagy suppression using LC3 siRNA-loaded "smart" nanoparticles (LC3siRNA-NPs) in combination with doxorubicin (DOX) to overcome chemoresistance in TNBC.

Istanbul Medipol University, School of Pharmacy, Department of Pharmaceutical Toxicology, 34815, Istanbul, Turkey.

The comet assay is a rapid, simple and sensitive method for the detection of DNA damage and repair at the level of individual cells, with a wide range of applications in human biomonitoring and molecular epidemiology. It is common practice to perform the comet assay on fresh samples to preserve the integrity of the DNA and to obtain reliable results, which is why most published studies have been designed using fresh blood samples. There are limitations associated with the use of fresh samples for this assay and the need for appropriate storage for some studies.
