AI Article Synopsis
- The study demonstrates that conjunctival impression cytology (CIC) is a practical, noninvasive alternative to biopsy for analyzing mRNA levels of mucin genes in ocular research.
- Using semiquantitative reverse-transcriptase polymerase chain reaction, researchers confirmed the expression of several mucin genes, including MUC7, in samples from healthy donors.
- The findings support the use of CIC to investigate gene expression in eye diseases, highlighting its effectiveness and convenience for patients.
Article Abstract
Purpose: To prove that noninvasive methods of obtaining conjunctival tissue, such as conjunctival impression cytology (CIC), could be valid alternatives that are simpler, faster, and more convenient for patients than biopsy to analyze mRNA levels of mucin genes.
Methods: Using the semiquantitative reverse-transcriptase polymerase chain reaction, we studied the presence of the mucin genes described on the ocular surface thus far and attempted to detect the presence of MUC7 in CIC samples from 10 healthy donors.
Results: Conjunctival cells recovered by CIC expressed all the genes studied. There were no statistically significant differences between male and female subjects, and there was a significant correlation between the two eyes of the same donor only in the expression of MUC7.
Conclusion: CIC is a valid, noninvasive technique to detect the mRNAs of ocular genes in healthy individuals. MUC1, MUC2, MUC4, MUC5AC, and MUC7 mucin genes could be all detected in each CIC sample. This technique may be a useful tool to study the expression of some genes in ocular diseases.
