In this study, Kaiso was discovered to be a unique member of the POZ-zinc fingers family of transcription factors, which has been implicated in the genesis and progression of cancer. Although there is still some debate, Kaiso is believed to be implicated in the development of human cancer. It should be noted that there is minimal evidence available on the therapeutic relevance of nuclear Kaiso in lung cancer in humans. Histone or DNA modifications that control gene activity outside of the underlying sequence are examples of epigenetic alternations. Epigenetic alterations are heritable but reversible. Human illness, such as lung cancer, is often related to epigenetic dysregulation. In preclinical and clinical studies, epigenetic-targeted therapy has shown significant therapeutic promise for solid tumours and has been used in the treatment of haematological malignancies using different medicines targeting epigenetic regulators. It is important to note that the abnormal activities of Kaiso enzymes in tumour growth are summarised below and the development of inhibitors or medicines targeting epigenetic enzyme regulation is highlighted.
