Cancer Biology: Oncogenes, Tumour Suppressors, and Multistep Carcinogenesis

Students will investigate the causes of climate change, focusing on the greenhouse effect and human activities, and its biological impacts.

Key Questions

  1. Explain how gain-of-function mutations in proto-oncogenes and loss-of-function mutations in tumour suppressor genes disrupt normal cell cycle control, applying the two-hit hypothesis to explain the recessive nature of tumour suppressor loss at the cellular level.
  2. Analyse the hallmarks of cancer — sustained proliferative signalling, evasion of apoptosis, induction of angiogenesis, and activation of invasion and metastasis — as consequences of cumulative somatic mutations, evaluating how each hallmark represents a targetable vulnerability.
  3. Evaluate the clonal selection model of tumour progression, explaining how successive rounds of mutation and natural selection within a growing tumour drive the stepwise acquisition of increasingly malignant phenotypes.
