PURPOSE: To determine the expression profiles of the transcription factor specificity protein 1 and collagen I in primary pterygial and normal conjunctival tissues, and to explore the role of specificity protein 1 and collagen I in pterygial development.
METHODS: The pterygial tissues of 20 patients who underwent resection of primary pterygial tissue in our hospital from June 2016 to December 2017 and the conjunctival tissues of 10 patients with enucleation due to trauma were collected. Reverse transcription quantitative-po lymerase chain reaction and western blot analyses were used to detect the relative expression levels of specificity protein 1 and type I collagen at the mRNA and protein levels.
RESULTS: The content of specificity protein 1 and collagen I mRNA and protein was significantly greater in primary pterygial tissue than it was in conjunctival tissue (p<0.05). There was a positive correlation between the mRNA and protein levels of specificity protein 1 and collagen I in primary pterygial tissues (protein: r=1, p<0.05; mRNA: r=1, p<0.05).
CONCLUSION: Specificity protein 1 and collagen I are expressed in normal conjunctival and pterygial tissues, but expression is significantly greater in the latter. Specificity protein 1 and collagen I may be involved in the regulation of the development of primary pterygium.
