New potential diagnostic markers for verrucous hyperplasia and verrucous carcinoma based on RNA-sequencing data.

Verrucous carcinoma (VC) is a rare subtype of squamous cell carcinoma (SCC) characterized by its histological presentation as a low-grade tumor with no potential for metastasis, setting it apart from invasive SCC. However, distinguishing VC from its benign counterpart, verrucous hyperplasia (VH), is challenging due to their clinical and morphological similarities. Despite the importance of accurate diagnosis for determining treatment strategies, diagnosis of VH and VC relied only on lesion recurrence after resection. To address this challenge, we generated RNA profiling data from tissue samples of VH and VC patients to identify novel diagnostic markers. We analyzed differentially expressed (DE) mRNA and long non-coding RNA (lncRNA) in tissue samples from VH and VC patients. Additionally, ChIP-X Enrichment Analysis 3 (ChEA3) was conducted to identify the top five transcription factors potentially regulating the expression of DE mRNAs in VH and VC. Our analysis of mRNA and lncRNA expression profiles in VH and VC provides insights into the underlying molecular characteristics of these diseases and offers potential new diagnostic markers. The identification of specific DE genes and lncRNAs may enable clinicians to more accurately differentiate between VH and VC, leading to better treatment choices. • Commonly upregulated mRNA in both VH and VC was enriched in keratinocyte differentiation and keratinization related processes • Upregulated mRNAs in VH were enriched in skin development and keratinocyte differentiation • Upregulated mRNAs in VC were enriched in response to stress and connective tissue development • Identified lncRNAs potentially influence the noninvasive phenotype in VH and less malignant behavior in VC • Our study provides new insights into the molecular mechanisms underlying VH and VC [ABSTRACT FROM AUTHOR]
