Every gene's message, the mRNA, carries a short leading stretch called the 5′ untranslated region (5′-UTR). This stretch does not code for protein but helps decide how much protein gets made.

What they work on

  1. Directly measure ribosome recruitment on thousands of 5′-UTR sequences, the leader regions of mRNAs, that are used differently in cancer cells, to identify functional RNA elements.
  2. Use computational methods to separate how individual 5′-UTR elements each contribute to ribosome recruitment and protein output.
  3. Identify the readers, factors that bind functional 5′-UTR elements, through combined biochemical and genetic studies.
  4. Characterize candidate readers in human cells and determine their role in the translational reprogramming seen in cancer.

More about the research

It does this by controlling how readily ribosomes, the cell's protein-making machines, land on the mRNA. Different 5′-UTRs can change protein output by about a thousand-fold, yet in most cases how they do so is unknown. Faulty protein production is linked to diseases such as cancer and neurodegeneration, so learning this 'regulatory code' matters for both basic biology and medicine.

Why it matters

Protein production goes wrong in cancer and neurodegenerative disease. Identifying the mRNA features and reader factors that set protein output could explain how cancer cells reprogram protein production. It could eventually point to new targets for treating diseases driven by faulty translation.

Known grants

From NIH and NSF research grants. Labs often have other funding we can't see.
