In this study, we investigated several molecules involved in the control of normal cell growth and development to determine whether they could help distinguish cancer tissue from healthy tissue and potentially help in determining prognosis of patients. We analyzed their expression in oral cancer cells grown in the laboratory and in tissue samples obtained from patients with oral cancer. We found that the levels of these molecules were significantly different between noncancerous and cancer tissues. When all three molecules were analyzed together, they showed improved ability to identify oral cancer. However, these molecules were not associated with predicting disease outcome. Our findings suggest that these biological markers may be useful for improving the detection of oral cancer and could contribute to the development of more accurate diagnostic tools in the future. Further studies involving larger numbers of patients are needed to confirm these results.  \nAbstract  \nIGF2-H19 locus is important for normal development and growth, and its deregulation has been implicated in various cancers, with conflicting data in oral cancer. IGF2 and H19 expression was analyzed in oral cancer (SCC-25, SCC-15) and normal keratinocytes (HaCaT) cell lines, as well as in cancer tissue and adjacent non-cancerous tissues from 55 patients with oral cancer. The expression of IGF2 and H19 was increased in oral cancer cell lines compared with control cell line. In clinical samples, expression of the IGF2-H19 locus and its associated hsa-miR-675-5p was significantly lower in cancer tissue compared with adjacent non-cancerous tissue. IGF2, H19, and hsa-miR-675-5p demonstrated moderate ability to discriminate between oral cancer and non-cancerous tissues, while the combined analysis of all three molecules improved diagnostic performance. Our results suggest that IGF2-H19 and hsa-miR-675-5p may have potential as molecular biomarkers for discriminating between oral cancer and non-cancerous tissue, but do not appear to have prognostic value.  \nKeywords: IGF2; H19; hsa-miR-483; hsa-miR-675; oral cancer  \n1. Introduction  \nHead and neck squamous cell carcinoma (HNSC) is a heterogenous group of cancers arising in the head and neck region, including oral cavity cancer [1] . Oral cancer (oralsquamous cell carcinoma, OSCC) is the most common subtype within this group, accounting for approximately 90% of all HNSC cases [2] .
