Abstract:
Objective To investigate the expression and significance of monoacylglycerol O-acyltransferase 2 (MOGAT2) in the tissues of pterygium.Methods Immunohistochemistry staining methods were adopted to detect the expression of MOGAT2 in 54 patients of pterygia (primary in 50 patients and recurrence in 4 patients)and 18 patients of normal conjunctival tissues.The semi-quantitative integration method was used to analyze the strength of immunohistochemical expression,and the results were compared and statistically analyzed,and the relationship between the expression of MOGAT2 in the pterygium group and the factors such as age,sex,and clinical pathological stage was analyzed.Results Immunohistochemical staining showed that,in 54 patients of pterygium,MOGAT2 was strongly expressed in 8 patients,positive expression in 29,weakly positive expression in 8 and negative expression in 9,while in 18 normal conjunctival tissues,strongly positive expression of MOGAT2 was found 1 patient,positive expression in 6,weakly positive expression in 3,negative expression in 8,respectively.Rank-sum test showed that the difference in MOGAT2 expression in the pterygium and normal conjunctiva tissues was statistically significant(Z =-2.403,P =0.016).There was no significant difference in the expression of MOGAT2 between the different age and the sex patients with pterygium (all P ＞ 0.05),and there was no significant correlation of MOGAT2 expression with education,occupation,income,protection in outdoor work,smoking,drinking,blood sugar,blood pressure,primary and recurrence pterygium,but significant correlation with the clinical stage of pterygium,that is,MOGAT2 expression in advanced pterygium was overexpressed when compared with tumor tissues in quiescent stage (P ＜ 0.05).Conclusion MOGAT2 is highly expressed in pterygium tissues,and the expression in advanced pterygium was significantly upregulated,of which is related to the formation and development of pterygium.
