Abstract
Study of the process of cancer initiation, growth and progression in altered gravity is of utmost importance considering the health status of researchers visiting in space and future scope of space tourism. Microgravity affects various cells in the body differently; however, the mechanisms of such effects are not understood completely. Therefore, it is imperative to explore various physiological and biochemical processes, particularly those which can influence the process of carcinogenesis. If the changes in physiological or biochemical processes do not revert back to normalcy even after returning from the space to earth, it may lead to various aberrations and morphological changes during the life span. Such changes could lead to pathological conditions including cancer. For example, microgravity is observed to suppress the activity of immune cells, which itself increases the risk of cancer development. It is little known how the microgravity affects cellular and molecular events that determine physiological and biological responses. There is also a possibility of changes in epigenetic signatures during microgravity exposure which remains unexplored. Herein, we have reviewed the effect of microgravity on relevant molecular and biological processes, and how it could influence the course of cancer development. In this regard, we have also highlighted the areas of research that require more attention to bridge the gap of understanding for such biological processes.

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
