Figure 2. GPX4 expression in thyroid cancer tissues and paracancerous tissues. High expression of GPX4 in thyroid cancer tissues (A) and low expression of GPX4 in paracancerous tissues (B) based on immunohistochemistry (Original magnification×40); scale bars: 50 μm. Expression of GPX4 at the mRNA level (C) and protein level (D) in different tissues (T, thyroid cancer tissues; P, paracancerous tissues, N=16). ****p<0.0001.
