Introduction: Akt, also known as protein kinase B, is a serine/threonine-specific protein-kinase which plays a key role in multiple cellular processes such as glucose metabolism, apoptosis, transcription and cell migration. The activation of Akt is one of the most frequent alterations observed in human cancer and tumour cells. Akt regulates cellular survival and metabolism by binding and regulating many downstream effectors, e.g., Nuclear Factor-kB, murine double minute 2(MDM2). Aims: To evaluate and compare immunohistochemical expression of Akt in normal epithelium and different histological grades of epithelial dysplasias. Materials and Methodology: Forty paraffin-embedded tissue sections were used for the immunohistochemical study of which 10 cases of normal epithelium, 10 cases of each mild, moderate and severe epithelial dysplasia which were diagnosed by haematoxylin and eosin procedures. The tissue sections were immunohistochemically analysed for expression of Akt in different grades of epithelial dysplasia by using anti-Akt-1 monoclonal antibody. Statistical analysis was carried out using statistical package for social science (SPSS, V 10.5). The data were analysed using Chi-square test and P < 0.05 was considered statistically significant. Results and Conclusion: An overall significant difference was observed when normal tissues were compared with epithelial dysplasia with a Chi-square value of 21.04, but there was no statistical significance between the three grades of epithelial dysplasias. In conclusion, this study suggests that Akt-1 overexpression can be one of the useful diagnostic markers for predicting the potential behaviour of oral dysplasias transforming into oral squamous cell carcinoma (OSCC).
