Abstract
MicroRNAs (miRNAs) control the expression of approximately 60% of protein-coding genes and regulate cell metabolism, proliferation, differentiation, and apoptosis. Notably, aberrant expression of miRNAs contributes to several diseases including cancer. Accumulating evidence indicates that miRNAs play important roles in EMT, genesis of cancer stem cells, cancer metabolism and carcinogenesis. Aberrant expression of miRNAs triggers tumor initiation, progression and poor prognosis of cancer patients. Accordingly, oncogenic miRNAs have emerged as diagnostic biomarkers and targets for novel anti-cancer drug discovery. However, the mechanisms of miRNAs contriving tumorigenesis are not completely understood. This review aims to clarify the identification of tumorspecific miRNAs, verification of oncogenic miRNA signatures, and dynamic study of oncogenic miRNAs in cancer initiation and development. Despite sound progress in miRNA-mediated anticancer therapy, several barriers like drug stability, immunogenicity, off-target effects and toxicities still remain. We hope our review could stimulate the further study of miRNAs in cancer research field, which may lead to new insights into the mechanisms of carcinogenesis and create new avenues for targeted cancer therapy.

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
