Abstract
Membrane transporters govern the movement of drugs and their metabolites across biological membranes, thereby determining their pharmacokinetics, efficacy and adverse drug reactions. Platinum-based anticancer drugs are a mainstay of chemotherapy for many human malignancies. However, their clinical utility is limited by tumor resistance and normal tissue toxicities, which are determined at least in part by the level of tissue accumulation of platinum. Recently, several members of the ATP-binding cassette (ABC), solute carrier (SLC) and ATPase membrane protein superfamilies have been found to contribute to the net accumulation of platinum drugs in malignant and normal tissues. Herein, a review has been carried out to critically evaluate current preclinical and clinical evidence implicating membrane transporters as determinants of the pharmacology of cisplatin, oxaliplatin, carboplatin and related investigational compounds. The evidence includes studies of recombinant cell systems with genetically modified expression of individual membrane transporters, platinum-resistant or -sensitive human cancer cells and in vivo xenografted tumors, animal models of platinum-induced nephro-, oto- or neurotoxicity, and clinical studies of associations between the membrane transporter tumor expression and patient outcomes from platinum-based chemotherapy. Understanding the role of membrane transporters as determinants of the pharmacology of platinum drugs will be a basis for targeting these drug transporters in individualized and optimized platinum-based cancer therapy, and new drug development.

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
