Abstract

The expression of nitric oxide synthase 1 (NOS1) and adenosine triphosphate-binding cassette sub-family G member 2 (ABCG2) in cervical cancer tissues was investigated. The messenger ribonucleic acid (mRNA) levels of NOS1 and ABCG2 in 40 cervical cancer specimens and 20 normal cervical specimens were detected via reverse transcription-polymerase chain reaction, and the correlation between them was analyzed via Pearson's correlation analysis. The protein expression levels were detected via western blotting. Moreover, the regulatory mode between NOS1 and ABCG2 and the effects on proliferation and apoptosis of cervical cancer cells were analyzed using the lentiviral transfection technique. The mRNA levels of NOS1 and ABCG2 in the cervical cancer group were significantly increased compared with those in the normal cervical control group (P<0.05). There was a positive correlation between NOS1 and ABCG2 mRNA expression levels in cervical cancer tissues (r=1.246, P=0.014). HeLa and C-33A cell lines with relatively high expression levels of NOS1 and ABCG2 were selected for the in vitro study. After interference in the NOS1 expression in HeLa and C-33A cells with sh-NOS1, the protein expression of ABCG2 was also decreased. However, the protein expression level of NOS1 remained unchanged after interference in the ABCG2 expression (P<0.05). After interference in the NOS1 expression, the proliferation capacities of HeLa and C-33A cells were significantly decreased, but the apoptosis levels were obviously increased (P<0.05). The mRNA expression of NOS1 and ABCG2 in cervical cancer tissues is significantly increased. NOS1, as an upstream signal regulator of ABCG2, regulates the growth and apoptosis of tumor cells. Both NOS1 and ABCG2 are important proliferation-promoting oncogenes in cervical cancer, which are expected to provide a certain theoretical basis for the treatment of cervical cancer.
