70704 - Genetics and Mitochondrial Metabolism of the Neoplastic Process

Academic Year 2018/2019

  • Teaching Mode: Traditional lectures
  • Campus: Bologna
  • Corso: Single cycle degree programme (LMCU) in Medicine and Surgery (cod. 8415)

Learning outcomes

Students will become familiar with the biochemical and mitochondrial pathways that become modified during neoplastic transformation and cancer progression, including the metabolic reprogramming at the level of the metastatic niche.

Course contents

Generalities of cancer metabolism.

Definition of neoplasia, basic concepts of cell transformation. Cancer as a genetic disease. Branched Darwinian evolution of cancer. Gene classes involved in cancerogenesis. Hallmarks of cancer and relevance of metabolic reprogramming. Warburg's observations, aerobic glycolysis and seminal hypotheses. Key metabolites in cancer cells. Physiological vs. interrupted Krebs cycle and anaplerosis. Carbon fluxes: pyruvate; citrate and its destiny; glutamine and glutaminolysis in both the aerobic and the anoxic mode. Waves of metabolic reprogramming. The central role of mitochondrial biogenesis, its stimuli and coactivators (PGC). Retrograde signaling between mitochondria and nucleus.

Oncogenes, tumor suppressors and their metabolic role.

Mitochondrial enzymes as tumor suppressor genes: paragangliomas and SDH mutations; leyomiomas and FH mutations; gliomas and IDH mutations. Metabolic consequences: role of HIF1 and pseudohypoxia. Epigenetics and oncometabolites: regulation of ketoglutarate-dependent dioxygenases.

Metabolism in the metastatic niche.

Epithelial-mesenchymal transition and links with cell metabolism. Brain, lung, liver, bone and omentum metastases and their metabolic features, including organ mimicry to evade the immune system.

Teaching methods

Up-front lectures with power point slides presentations. The class will be invited to talke active part in the discussion of issues raised during the lectures.

Assessment methods

Multiple choice test. The test poses 6 different questions with three possible answers one of which only is correct. The test is passed by answering correctly to three of the six questions.

No mark is foreseen for this optional course. Pass or not pass will be awarded according to the result of the final examination.

Teaching tools

Powerpoint slides
Scientific papers

Teaching material will be provided at the end of each class on the on line platform. Textbooks and papers are not considered compulsory readings.
