Abstract:
[Abstract] Objective: To investigate the expression of lysosome-associated membrane protein 3 (LAMP3) and activating transcription factor 4 (ATF4) in cervical cancer and their correlation with clinicopathological parameters. Methods: The expression of LAMP3 and ATF4 in normal cervical tissues, cervical intraepithelial lesions, and cervical cancer tissues was detected by SP immunohistochemistry. The relationships between the expression of these two proteins and patient clinicopathological parameters were analyzed, as well as the correlation between LAMP3 and ATF4 expression. Results: LAMP3 was negative or lowly expressed in both normal cervix tissues and high-grade squamous intraepithelial lesions, but highly expressed in cervical cancer tissues (38.3%), showing a statistically significant difference (χ2 = 14.113, P = 0.001). ATF4 was highly expressed in 26.7% of the normal cervix tissues, 10.0% of the high-grade squamous intraepithelial lesions, and 58.3% in the cervical cancer tissues, also showing a significant difference (χ2 = 11.078, P = 0.004). In cervical cancer, LAMP3 expression was significantly associated with FIGO stage (χ2 = 10.139, P = 0.006) and lymph node metastasis (χ2 = 8.475, P = 0.004); ATF4 expression was significantly associated with tumor size (χ2 = 4.578, P = 0.032), FIGO stage (χ2 = 8.971, P = 0.009), and lymph node metastasis (χ2 = 7.881, P = 0.005). There was a positive correlation between the expression of LAMP3 and ATF4 in cervical cancer tissues (r = 0.388, P = 0.002). Conclusion: LAMP3 and ATF4 are highly expressed in cervical cancer tissues and are positively correlated. Both of them play important roles in the development and progression of cervical cancer and could serve as potential therapeutic targets for cervical cancer treatment.
