Abstract
Epithelial-mesenchymal transition (EMT) is a vital process implemented in embryo development, organ fibrosis, and cancer metastasis. Several transcription factors and signaling pathways impinge on the transcriptional program of the cell, leading to the change of cell phenotype without alteration of genotype. Accumulating evidence suggests that epigenetic mechanisms play important roles in inducing EMT and orchestrating the heredity and reversibility of EMT. In this review, we discuss how DNA methylation, histone modifications, and microRNAs (miRNAs) act in a concerted manner to regulate EMT. ‘Epigenetic therapies’—inhibitors of DNA methyltransferases and histone deacetylases as well as microRNAs are emerging as promising agents for cancer intervention.
Keywords: DNMT inhibitors, EMT, epigenetic regulation, epigenetic therapy, HDAC inhibitors, metastasis, miRNAs.

Advances in Cancer Biomarkers and Potential Drug Targets: From Diagnosis to Therapy
Cancer biomarkers play a crucial role in the diagnosis, prognosis, and treatment of cancer. They provide valuable information for cancer detection, risk assessment, treatment selection, and monitoring response to therapy. With advancements in molecular biology and high-throughput technologies, there has been an increasing interest in identifying and characterizing cancer biomarkers ...read more
Novel Therapeutic Approaches to Target Drug Resistant Tumors
With the development of disciplines such as chemical biology and molecular biology, the genes or proteins closely related to tumor occurrence and development have gradually become clear. Targeted therapies targeting these genes or proteins provide more effective methods for tumor treatment. Tumor targeted drugs generally only act on specific targets ...read more
ROLE OF IMMUNE AND GENOTOXIC RESPONSE BIOMARKERS IN TUMOR MICROENVIRONMENT IN CANCER DIAGNOSIS AND TREATMENT
Biological biomarkers have been used in medical research as an indicator of a normal or abnormal process inside the body, or of a disease. Nowadays, various researchers are in process to explore and investigate the biological markers for the early assessment of cancer. DNA Damage response (DDR) pathways and immune ...read more
Targeting the battlefield between host and tumor: basic research and clinical practice on reshaping tumor immune microenvironment
Immune system protects host against malignant tumors through effector cells and molecules. Cancer development and its response to therapy are regulated by inflammation, which either promotes or suppresses cancer progression. Chronic inflammation facilitates cancer progression and treatment resistance, whereas induction of acute inflammatory reactions often lead to anti-cancer immune responses. ...read more
