Abstract
For many years, the vitamin A metabolite retinoic acid (RA) has been known to have profound effects on development, cellular proliferation and differentiation, and tumor growth and invasion. The wide-ranging effects of RA on cellular proliferation and migration have made it a useful chemotherapeutic agent in the treatment of many types of cancer. In the last fifteen years, with the discovery of nuclear receptors for RA, the molecular basis for the effects of this molecule has become apparent. Retinoic acid receptors (RAR) are members of a superfamily of ligand dependent transcription factors that interact with an increasingly large array of coactivators and repressors to regulate target gene expression through binding to cognate recognition sequences in the promoters of these genes. Alterations in RAR expression and function have been demonstrated in many types of cancer. The translocation of RARα with PML or PLZF genes in acute promyelocytic leukemia is a paradigm of the role of RARs in cancer biology. In addition, the development of receptor selective synthetic retinoids has greatly expanded our knowledge of RAR function in tumor cells and provided additional treatment options for cancer patients. This review will examine the development of receptor selective retinoids, their uses to date, and future potential.

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
