Abstract
In the recent years, significant development of molecular genetics has contributed to the better understanding of leukemogenesis and classification of the different leukemia subtypes. Patients diagnosed with acute leukemia usually undergo chemotherapy, which involves the induction of remission, consolidation of remission and maintenance therapy. Patients are still vulnerable to relapse due to differences in the sensitivity of leukemia cells to the chemotherapeutic agent, because of the active drugs removal from the cells, improving the repair of DNA damage or abnormalities in the apoptotic pathway. Cell adhesion and miRNA expression level also affect the drug resistance. New candidate genes and genes correlated with the disease have been sought to increase the survival of patients with leukemia. Candidate gene is usually a loci located in a certain chromosomal region suspected of involvement to the disease course or its expression product regulates disease progression. There are classic and digital methods of finding candidate genes. These techniques are inexpensive, quick and easy to carry out. Unfortunately, due to insufficient knowledge of the disease etiology and low accuracy, researchers cannot detect all genes, involved in leukemogenesis and cell resistance. Currently, scientists have many tools used for selecting genes, such as expression microarrays, comparative genomic hybridization and next generation sequencing. Among the validation techniques for candidate genes, the mostly used ones are fluorescent in situ hybridization and real-time PCR. In our review we present 18 candidate genes of resistance to therapy in childhood leukemia.

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
