Henry M. Lemon Short Course in Cancer Biology

The 2026 course is scheduled for June 29-30 and will focus on Structural Molecular Biology in Cancer Research.

This annual course brings together leading scientists to address important topics in cancer research. The course will be held at the Fred & Pamela Buffett Cancer Center in the Gail and Mike Yanney Conference Center, BCC 0.12.101. 

Course Overview 

The short course will cover the full spectrum of DNA biology, from how cells survive and grow, to aging, advanced experimental methods, and new insights into correcting replication errors—the main source of cancer-causing mutations—and will conclude with lessons on the repair of DNA base damage and its role in cancer.

The graphical abstract shows three key ideas. The top row illustrates healthy cells dividing over a long lifespan. The middle row shows different types of DNA damage that can lead to cancer cell proliferation. The bottom row shows how bubble models can be replaced with detailed molecular models, which enables the development of targeted therapies.

Day 1: DNA Damage Response and Cellular Lifespan 

Learning objectives: 

  1. Explore the DNA damage response (DDR) in the context of fundamental biology for replication and transcription, processes required for cell survival and proliferation. 
  2. Describe how DDR repairs different types of DNA damage, from bulky damage to DNA breaks, to allow cells to survive while limiting genome instability. 
  3. Connect double-strand DNA break repair to mitotic lifespan, with insights into aging and cellular lifespan. 

Day 2: DNA Repair Assays and Cancer-Relevant Insights 

Learning objectives: 

  1. Examine specific assays to find new roles for mismatch repair (a DNA replication-associated repair) and nucleotide excision repair (repair of bulky lesions, a transcription-associated repair) and connect these findings back to Day One concept. 
  2. Discuss nucleobase damage, the most common form of DNA damage, and understand the structural and mechanistic insights that link fundamental DNA biology and repair to cancer risk.
