Analysis of the effect of trichloroacetic acid and epidermal growth factor release on cytoskeleton gene expression using the nano-controlled releasing system / 대한치과보철학회지

ABSTRACT

Purpose@#Here, we verified that the actin cytoskeletal gene expression of human gingival fibroblasts was altered by the administration of trichloroacetic acid (TCA) and epidermal growth factor (EGF) using the nano-controlled releasing system. @*Materials and methods@#The control and experimental groups were divided into 3 groups the group with the TCA-only nano-controlled releasing system (EXP1), the group with the TCA- and EGF nano-controlled releasing system (EXP2), and the control group (CON) with 48-h incubation. Expression of 26 genes involved in the regulation of actin cytoskeleton were analyzed by real-time PCR followed by the determination of correlations and influential factors using the Pearson correlation analysis and multiple regression analysis. @*Results@#Among 23 genes upregulated in EXP1 and EXP2, expression of 14 genes were significantly increased in EXP2 compared to EXP1. On the other hand, LPAR1 was downregulated only in EXP1, GNA13 was upregulated only in EXP2, and F2R was downregulated only in EXP2. Three Rac1-related genes and CDC42 were identified as the influential factors of the actin gene upregulation. @*Conclusion@#The actin cytoskeleton genes in human gingival fibroblast were upregulated by the administration of TCA and EGF using HGC-based nano-controlled releasing system.
