Figure Lengend Snippet: Proposed model of PRDX4-mediated suppression of ferroptosis through regulation of the PI3K/AKT pathway in ESCC. PRDX4 is highly expressed in ESCC samples and cells. High PRDX4 expression is strongly associated with TNM staging and lymph node metastasis in patients with ESCC and may serve as an indicator of prognosis for patients with ESCA. PRDX4 knockdown suppresses cell proliferation and invasion of ESCC cells by inactivating the PI3K/AKT signaling pathway, thereby triggering ferroptosis in these cells.
