Animation exposes tricks of crucial tumour protein

The most recent animation innovation has actually exposed the molecular information of how our bodies are secured from cancer by a crucial ‘tumour suppressor’ protein called p53.

The brand-new WEHI-TV animation visualises discoveries from more than 40 years of research study to describe how the tumour suppressor protein p53 usually avoids cancer-causing modifications in cells. Over half of human cancer cases include defective p53.

The animation was produced by WEHI.TV biomedical animator Ms Etsuko Uno, who worked carefully with WEHI cancer scientists Teacher Andreas Strasser and Dr Gemma Kelly to make sure the animation’s clinical precision.

  • Controlling cell life and death
  • In our bodies, p53 is an important controller of cellular division, cell death and DNA repair work, guaranteeing that healthy cells can divide as required, however requiring cells with broken DNA to stop dividing and go through repair work – or pass away, if the damage is too extreme. These procedures are crucial for preserving health; cancer is brought on by harmed cells being permitted to continue and grow frantically.

Cancer scientist Dr Gemma Kelly, who likewise told the animation, stated majority of human cancers bring problems in p53.

” The most regularly altered gene in human cancer is p53 – and it is, I believe, the most essential ‘tumour suppressor’ protein. Anomalies of the p53 gene are especially typical in numerous common cancer types with bad diagnosis, consisting of lung cancer, ovarian cancer and pancreatic cancer,” she stated.

” In spite of 40 years of extreme research study into p53, there is still a lot to discover how this tumour suppressor works, in order to establish much better treatments for cancers that have faulty p53.”

Utilizing animation to comprehend science

The brand-new WEHI.TV animation was produced to plainly describe the current understanding about p53, stated its developer Ms Etsuko Uno.

” Working carefully with our scientists, I had the ability to produce really intricate images of p53 operating within cells, which show the most current information about this tumour suppressor,” she stated.

” This has actually been among the most difficult proteins I have actually highlighted, due to the fact that – unlike a lot of other proteins I have actually dealt with – this protein is mostly disorganized. WEHI’s structural biology scientists supplied important assistance on how to properly illustrate it.”

” To develop the in-depth molecular shapes and motions, we relied on innovations utilized to make video game, utilizing a production software application called Unity,” Ms Uno stated.

Describing p53’s function

The brand-new animation shows how p53 reacts to DNA damage in cells, ‘switching on’ the production of proteins that can fix the damage. It likewise stops the cells dividing, to enable time for this repair work and avoid mistakes in genes being transferred to brand-new cells. Nevertheless, if the damage is too extreme, p53 provides its last blow, directing the production of ‘cell death’ proteins that activate the cell’s death, by a configured cell death procedure called apoptosis.

The animation likewise describes how breakdowns in p53 can cause cancer advancement, by not properly fixing DNA damage within cells.

Cancer scientist Teacher Andreas Strasser stated the animation supplied a vibrant and available description of how tumour suppressors within our cells work to avoid cancer establishing. “It’s a fantastic academic resource, which plainly describes how p53 safeguards us from cancer,” he stated.

” I am enjoyed see how it integrates the current discoveries about how p53 functions – consisting of discoveries made by my own research study group – included in a vibrant and clinically precise method.”


Teacher Strasser and Dr Kelly’s research study into p53 has actually gotten significant assistance from the Dyson Bequest, The Craig Perkins Cancer Research Study Structure, the National Health and Medical Research Study Council, the Victorian Cancer Company, Cancer Council Victoria, the Leukemia Structure of Australia, the Redstone Structure Bequest and the Victorian Federal government. .
