Odontogenic keratocysts (OKC) are locally aggressive jaw lesions characterized by a high recurrence rate. Vimentin 3 (VIM3), a truncated splice variant of full-length vimentin (VIMFL), has recently emerged as a potential biomarker in odontogenic tumors.
However, its role in OKC and association with recurrence remain unexplored. Formalin-fixed paraffin-embedded samples from OKC (n = 25) and dentigerous cysts (DC) (n = 25) were analyzed. Immunohistochemical staining for VIM3, VIMFL, p53, and Ki-67 was performed. In parallel, reverse transcription-quantitative polymerase chain reaction was used to assess mRNA expression levels of VIM3, VIMFL, and p53.
While VIM3 expression did not significantly differ between OKC and DC, recurrent OKC exhibited significantly higher VIM3 labeling indices compared to non-recurrent cases (p = 0.040).
This study demonstrates, for the first time, the expression of VIM3 in OKC. Although the findings are promising, further research with larger cohorts and functional validation is required to clarify the mechanistic role of VIM3 in odontogenic cyst biology.
