They engaged the MCF-7, Rapa (rapid adenovirus production and amplification), siRNA (double stranded RNA) cell lines and LC3-autophagy marker for the ATG4B detection as depicted in Figure 7B. Based on the AIE-based turn-on in vivo/in vitro autophagy detection and cancer cell tracking ability, the DPBP can be attested as a potential candidate for cancer diagnostics. Here, ATG4B is linked to cancer.
