Abstract

Precision medicine might be the response to the recent questioning of the use of metformin as an anticancer drug in colorectal cancer (CRC). Thus, in order to establish properly its benefits, its application need to be assayed on the different progression stages of CRC. In this way, organoids imply a more physiological tool, representing a new therapeutic opportunity for CRC personalized treatment to assay tumor stage-dependent drugs effects. Since the lipid metabolism-related axis, ACSL/SCD, stimulates colon cancer progression and Metformin is able to rescuing the invasive and migratory phenotype conferred to cancer cells upon this axis overexpression; we checked ACSL/SCD status, its regulatory miRNAs and the effect of Metformin treatment in organoids as a model for specific and personalized treatment. Despite ACSL4 expression is upregulated in CRC-like organoids, Metformin is able to downregulate it, especially in the first stages. Besides, organoids are clearly more sensitive in this first stage (Apc mutated) to Metformin than current chemotherapeutic drugs such as fluorouracil (5-FU). Metformin performs an independent “Warburg effect” blockade to cancer progression and is able to reduce crypt stem cell markers expression su...Continue Reading

Cancer Metabolism

In order for cancer cells to maintain rapid, uncontrolled cell proliferation, they must acquire a source of energy. Cancer cells acquire metabolic energy from their surrounding environment and utilize the host cell nutrients to do so. Here is the latest research on cancer metabolism.

Cancer Metabolic Reprogramming

Cancer metabolic reprogramming is important for the rapid growth and proliferation of cancer cells. Cancer cells have the ability to change their metabolic demands depending on their environment, regulated by the activation of oncogenes or loss of tumor suppressor genes. Here is the latest research on cancer metabolic reprogramming.
