Abstract

Esophageal cancer is one of the most common cancer types in humans worldwide. Photodynamic therapy (PDT) is a promising therapeutic strategy for the treatment of cancer. However, its underlying mechanism needs to be studied thoroughly. The present study focused on the antitumor effect and underlying mechanism of the use of hematoporphyrin derivative (HpD)‑PDT against human esophageal squamous cell carcinoma cells via regulation of the PI3K/AKT/mTOR signaling pathway. A Cell Counting Kit‑8 assay was used to measure cell viability. Migration was evaluated using a wound healing assay. An annexin V‑FITC/PI kit was used to determine cell apoptosis rates. Protein expression levels were analyzed via western blotting. Reverse transcription‑quantitative PCR was used to detect gene expression levels. A 2',7'‑dichlorodihydrofluorescein diacetate kit was chosen to evaluate intracellular reactive oxygen species levels via flow cytometry. Cell viability and migration were decreased in KYSE‑150 cells after HpD‑PDT treatment. Cellular apoptosis was induced after HpD‑PDT treatment, and the same trend was observed for autophagy. Furthermore, the PI3K/AKT/mTOR signaling pathway was inhibited. The viability and migration of KYSE‑150 cells were significantly inhibited, and apoptosis was induced more effectively following treatment with a combination of HpD‑PDT and the PI3K inhibitor, a final concentration of 20 µM LY294002. In conclusion, HpD‑PDT could suppress esophageal cancer cell viability, induce apoptosis and inhibit migration by downregulating the PI3K/AKT/mTOR signaling pathway. Combination of HpD‑PDT with PI3K inhibitor (LY294002) could enhance the therapeutic efficacy compared with that demonstrated by HpD‑PDT alone. Further studies on combination therapy are required to achieve improved clinical outcomes.
