Supervisor:Dr Susanne Bornelöv
Deadline for application:31st October 2024
Course start date:1st October 2025
Overview
Dr Susanne Bornelöv wishes to recruit a student to work on the project entitled: "Unlocking the code within the code: Using AI to decipher the role of codon usage in protein synthesis and gene regulation".
This is a unique opportunity for PhD study in the world-leading Cancer Research UK Cambridge Institute (CRUK CI), to start a research career in an environment committed to training outstanding cancer research scientists of the future.
The Institute's particular strengths are in genomics, computational biology and imaging; and significant research effort is currently devoted to cancers arising in the breast, pancreas, brain, and colon. Our Core Facilities provide researchers with access to state-of-the-art equipment, in-house expertise and training. Scientists at CRUK CI aim to understand the fundamental biology of cancer and translate these findings into the clinic to benefit patients.
There are around 100 postgraduate students at the Cambridge Institute, who play a vital and pivotal role in its continuing success. We are committed to providing an inclusive and supportive working environment that fosters intellectual curiosity and scientific excellence.
Project details
The genetic code contains 61 codons encoding 20 amino acids and most amino acids are therefore encoded by two or more 'synonymous' codons. Despite producing the same protein, the choice of one synonymous codon over another plays an important role in gene regulation [1,2]. Some codons slow down translation, which in turn triggers mRNA degradation and halt protein synthesis. Protein synthesis is often dysregulated in cancer, making mRNA translation an attractive therapeutic target.
This project uses artificial intelligence (AI) to unravel the underlying mechanism by which codon-level information regulates translation.
Our group uses computational methods to study the inner workings and control of biological systems. For instance, by systematically changing the input mRNA sequence to a model capable of predicting mRNA stability or localisation, and analysing resultant patterns, we can gain understanding of what sequence elements regulate these processes. Additionally, we can use disease-associated alterations as inputs to unravel the underlying mechanism.
These models enable us to conduct experiments on a scale far surpassing what is achievable through traditional methods. The primary challenge lies in making models that accurately capture the complexities of biological systems [3]. In this project, you will use cutting-edge deep learning techniques, such as foundation models, to address this challenge. Foundation models, such as those underlying ChatGPT, are trained on a vast array of data and are capable of generalising across a multitude of problems. Your work will use similar models, but trained on 'omics' data, to study the regulation of translation.
