Abstract
We have analyzed the response of primary cultures derived from tumor specimens of non small cell lung cancer (NSCLC) patients to choline kinase α (ChoKα) inhibitors. ChoKα inhibitors have been demonstrated to increase ceramides levels specifically in tumor cells, and this increase has been suggested as the mechanism that explain its proapoptotic effect in cancer cells. Here, we have investigated the molecular mechanism associated to the intrinsic resistance, and found that other enzyme involved in lipid metabolism, acid ceramidase (ASAH1), is specifically upregulated in resistant tumors. NSCLC cells with acquired resistance to ChoKα inhibitors also display increased levels of ASAH1. Accordingly, ASAH1 inhibition synergistically sensitizes lung cancer cells to the antiproliferative effect of ChoKα inhibitors. Thus, the determination of the levels of ASAH1 predicts sensitivity to targeted therapy based on ChoKα specific inhibition and represents a model for combinatorial treatments of ChoKα inhibitors and ASAH1 inhibitors. Considering that ChoKα inhibitors have been recently approved to enter Phase I clinical trials by the Food and Drug Administration (FDA), these findings are anticipating critical information to improve the clinical outcome of this family of novel anticancer drugs under 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
