Objective:
The current study was designed to examine the expression of Skp2 gene in laryngeal squamous cell carcinoma (LSCC) and to investigate the role of Skp2 gene in tumorigenesis and progression of LSCC.
Method:
FQ-PCR method was used to examined the expression of Skp2 gene in 40 LSCC and 10 normal laryngeal mucosa tissues, and relationship between its expression and clinical biological factors of patients with LSCC was analyzed.
Result:
The median copy number of Skp2 mRNA expression in LSCC was 6622.54 copy/microg RNA, the median copy number of Skp2 mRNA expression in normal laryngeal mucosa tissues was 0 copy/microg RNA, there was a very significant difference between them (P < 0.01); The positive rate of Skp2 mRNA expression in LSCC and adjacent normal laryngeal tissue were 50%, 0, respectively (P < 0.01). The median copy number of Skp2 RNA expression in LSCC with cervical lymph node metastasis was 617138.4 copy/microg RNA, the median copy number of Skp2 mRNA expression in LSCC without cervical lymph node metastasis was 0 copy/microg RNA, there was a very significant difference between them (P < 0.05); The positive rate of Skp2 mRNA expression in LSCC with and without cervical lymph node metastasis were 100.00%, 35.48%, respectively (P < 0.01).
Conclusion:
Skp2 gene might have relation with the cervical lymph node metastasis of LSCC. FQ-PCR is an accurate assay to detecting expression of Skp2 mRNA in patient with LSCC. The level of Skp2 mRNA expression might be a new and more accurate marker, and it can be used to predict cervical lymph node metastasis of LSCC.
