Abstract:
Objective:To investigate the expression of F-spondin (SPON1) in cervical cancer tissues and its effects on the biological behavior of Hela cell line, including proliferation, apoptosis, invasion, and migration.Method:Select 80 samples of cervical cancer tissue and 80 samples of cervical inflammation tissue stored in the Pathology Department of Xuzhou Medical University from January 2022 to May 2023. Immunohistochemistry was used to detect the expression of SPON1 in cervical cancer and chronic cervicitis tissues, and the corresponding clinicopathological data were collected for analysis. Small disturbance RNA(siRNA) was used to interfere with the expression of SPON1 in Hela cell lines. Untransfected cells were set as normal control group (Ctrl group), negative control group (NC siRNA group), and siRNA knockout group (SPON1 siRNA group). The interference effect was detected by qPCR and Western blot. Cell proliferation assay (CCK-8), flow cytometry, Transwell, and scratch assay were used to detect the proliferation, apoptosis, invasion, and migration of each group of cells. Each experiment was repeated three times. Quantitative data that conforms to a normal distribution are represented by xˉ± s. The comparison of means among the three groups was conducted using one-way analysis of variance; Compare pairwise using LSD- t test. Calculate the percentage based on qualitative data, and compare the rates between groups using the chi square test. P<0.05 indicates a statistically significant difference. Results:Compared with the chronic cervicitis group, the positive expression rate of SPON1 in cervical cancer tissues (72.5% (58/80)) was higher than that in chronic cervicitis tissues (20.0% (16/80)), and the difference was statistically significant ( χ2=44.35, P<0.001). The positive expression rate of SPON1 was positively correlated with the clinical stage, pathological differentiation and tumor diameter of cervical cancer ( χ2 values were 4.10, 4.98, and 4.40, respectively; P values were 0.043, 0.026, and 0.036, respectively), and were not related to the age and tissue type of patients ( χ2 values were 0.72 and 0.14, P values were 0.386 and 0.713, respectively). The relative expressions of SPON1 mRNA were 1.000±0.014, 0.966±0.082, and 0.365±0.036, respectively. The expression levels of SPON1 protein were 1.000±0.013, 1.022±0.031, and 0.655±0.026, respectively. The number of cells that penetrated the model in the three groups was (113.3±4.1), (107.0±3.1), and (80.3±3.2), respectively. The wound healing rates of the three groups were (56.00±3.45)%, (55.00±5.03)%, and (35.33±3.76)%, respectively, and the apoptosis rates of the three groups were (5.88±0.44)%, (6.27±0.38)%, and (10.50±0.39)%, respectively. Compared with the Ctrl group and the NC-siRNA group, the proliferation ability of cells in the siRNA interference group decreased (all P<0.001), invasion ( P values were 0.001 and 0.004) and migration ( P values were 0.029 and 0.035), and the apoptosis rate was increased ( P=0.001). Conclusion:SPON1 is highly expressed in cervical cancer tissue and is associated with the occurrence and development of cervical cancer. Inhibiting SPON1 expression significantly reduces the proliferation, invasion, and migration ability of Hela cells, and promotes their apoptosis.
