Background: High-risk human papilloma virus (HR HPV) infection is a major factor leading to the development of uterine cervical cancer. Data suggest that alterations in lipid metabolism are related to the pathogenesis of cervical cancer. Specifically, the uptake of exogenous fatty acids and their intracellular storage in lipid droplets enables cancer cells to survive and adapt to the changing tumor environment. Materials and Methods: We compared the immunohistochemical expression of fatty acid transport protein 4 (FATP4), and cluster of differentiation 36/fatty acid translocase (CD36/FAT) in normal cervical epithelium, low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), and squamous cell carcinoma (SCC) tissues of the uterine cervix. We also investigated the clinicopathological implications of these fatty acid transporters in SCC. Results: Compared with that in normal cervical tissues, the expression of FATP4 was lower in LSIL (p=0.002), HSIL (p=0.006), and SCC (p=0.001). In contrast, CD36 expression was higher in SCC tissues than in normal cervical tissues (p<0.001). In normal cervical tissues, HR HPV-infected lesions exhibited a decrease in FATP4 (p<0.001) and an increase of CD36 (p=0.134), compared to those that were not infected with HR HPV. High CD36 expression was associated with a shorter recurrence-free survival (p<0.001). However, high FATP4 levels showed no significant correlation with the clinicopathological parameters of SCC. Conclusion: Altered expression levels of FATP4 and CD36 are unique features that might be related to HR HPV infection and promote tumorigenesis and progression of cervical cancer.
