ROLE OF CIRCULATING MIR-21 EXPRESSION PROFILES AND THEIR EMERGENCE AS POTENTIAL BIOMARKERS IN ORAL SQUAMOUS CELL CARCINOMA

Among the widest range of prevalent forms of cancer is oral carcinoma, which can develop anywhere in the mouth or even on the lips. Although there have been many advances in cancer treatment, the expected lifespan for OSCCs have indeed increased marginally. The load of OSCC is anticipated to increase in the near future, yet there is no sign of relief in view. Tumorigenesis is just one of the many physiological processes that can be controlled by microRNAs, a class noncoding endogenous RNAs. Several fibrosis disorders have been linked to miR- 21, and it has been utilised to distinguish oral and tongue cancer from healthy individuals. Studies empirically highlighted the significance of these transcripts as a predictor for prediction and diagnosis in OSCCs. Therefore, the present review summarizes the expression levels of miRNAs in OSCCs and evaluates their functioning in the progression or suppression of cancer. miR-21 can be considered as a prospective candidate for their translational use in OSCCs for early diagnosis prognosis surveillance and tailored treatment which should undergo further validation.
