The expression of lnc-CCDC170-4:1, ESR1, lncRNA SRA, and CYP19A1 in cervical squamous cell carcinoma and their relationship with the clinical characteristics.

Abstract

The occurrence of cervical cancer may be related to estrogen and estrogen receptors. This study investigated the expression of lnc-CCDC170-4:1, ESR1 (estrogen receptor 1), lncRNA SRA, and CYP19A1 (aromatase) in cervical squamous cell carcinoma tissues, as well as their relationship with the clinical characteristics of patients. Whole transcriptome sequencing analysis was performed on cervical squamous cell carcinoma tissues (n=4) and normal tissues (n=4). The expressions of lnc-CCDC170-4:1, ESR1, lncRNA SRA, and CYP19A1 were validated in 26 cases of cervical cancer tissue and 30 cases of normal cervical tissue using qRT-PCR. The relationship of gene expression with the clinical characteristics and 5-year overall survival rates of cervical cancer patients was analyzed. The expression levels of CYP19A1 and lncRNA SRA were upregulated, while those of ESR1 and lnc-CCDC170-4:1 were downregulated in cervical squamous cell carcinoma tissue. However, their expression was not related to 5-year overall survival rates (p>0.05). Low expression of lnc-CCDC170-4:1 was associated with lymph node metastasis (p=0.030) and Tumor size (p=0.047), Low expression of ESR was associated with FIGO Staging (p=0.041)and Tumor size(p=0.002),High expression of LncSRA was associated with FIGO Staging(p=0.004). Estrogen and estrogen receptors may play a role in the occurrence and development of cervical squamous cell carcinoma. Low expression of lnc-CCDC170-4:1 and ESR1 are associated with lymph node metastasis and FIGO stage, so it may be a potential biomarker to evaluate the prognosis of cervical cancer.
