过氧化物酶家族在维持细胞内活性氧平衡中起着至关重要的作用。然而,其在头颈部鳞状细胞癌(HNSCC)中的功能尚未研究。因此,我们探讨了PRDX在HNSCC中的价值。我们发现PRDX1、PRDX4和PRDX5在HNSCC中的表达增加,而PRDX2的表达减少。PRDX4/5/6的高表达提示预后不良。PRDX1/5的较低表达与更多的免疫细胞浸润、更高的免疫相关分子表达以及对抗PD-1治疗的更可能反应有关。此外,PRDX5基因敲低可抑制HNSCC细胞增殖、侵袭和转移,并可能通过其抗氧化特性促进细胞凋亡。总之,我们的研究强调了PRDXs在HNSCC中的潜在作用。PRDX5在HNSCC的发展和免疫微环境的形成中的功能使其成为有希望的潜在治疗靶点。
The peroxidase family of peroxiredoxins (PRDXs) plays a vital role in maintaining the intracellular balance of ROS. However, their function in head and neck squamous cell carcinoma (HNSCC) has not been investigated. We therefore explored the value of PRDXs in HNSCC. We found that the expression of PRDX1, PRDX4, and PRDX5 in HNSCC increased while the expression of PRDX2 decreased. Moreover, the high expression of PRDX4/5/6 indicated a poor prognosis. Lower expression of PRDX1/5 was linked to more immune cell infiltration, higher expression of immune-related molecules and a more likely response to anti-PD-1 treatment. Moreover, PRDX5 knockdown inhibited HNSCC cell proliferation, invasion and metastasis and it might promote apoptosis through its antioxidant property. Taken together, our study highlights the potential role of PRDXs in HNSCC. The function of PRDX5 in the development of HNSCC and the formation of the immune microenvironment makes it a promising potential therapeutic target.
