Abstract
Background: Glioblastoma multiforme (GBM) continues to devastate patients and outfox investigators and clinicians despite the preponderance of research directed at its biology, pathogenesis and therapeutic advances. GBM routinely outlasts multidisciplinary treatment protocols, almost inevitably recurring in a yet more aggressive and resistant form with distinct genetic differences from the original tumor. Attempts to glean further insight into GBM point increasingly toward a subpopulation of cells with a stem-like phenotype. These cancer stem cells, similar to those now described in a variety of malignancies, are capable of tumorigenesis from a population of susceptible cells.
Conclusions: Glioma stem cells have thus become a prevalent focus in GBM research for their presumed role in development, maintenance and recurrence of tumors. Glioma stem cells infiltrate the white matter surrounding tumors and often evade resection. They are uniquely suited both biochemically and environmentally to resist the best therapy currently available, intrinsically and efficiently resistant to standard chemo- and radiotherapy. These stem cells create an extremely heterogenous tumor that to date has had an answer for every therapeutic question, with continued dismal patient survival. Targeting this population of glioma stem cells may hold the long-awaited key to durable therapeutic efficacy in GBM.Keywords: Chemotherapy, drug targets, glioblastoma multiforme, glioma stem cells, niches, resistance, recurrence.

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
