What this research studies

This project uses laboratory experiments to observe how Mycobacterium tuberculosis turns genes on and off and repairs DNA damage. Scientists focus on bacterial transcription factors called CarD and RbpA and use purified proteins, ensemble and single-molecule biophysics, and kinetic modeling to watch key steps in transcription initiation. The team will also compare findings to related processes in yeast and human systems to clarify shared mechanisms. By revealing core bacterial dependencies, the work aims to point to new antibiotic targets to combat drug-resistant TB.

Who could benefit from this research

Good fit: People with active or drug-resistant tuberculosis would be the likely eventual candidates for therapies that arise from this research.

Not a fit: People without tuberculosis or with non-bacterial lung conditions are unlikely to benefit directly from this laboratory-focused work.

Why it matters

Potential benefit: If successful, the work could reveal new targets for antibiotics that better treat drug-resistant tuberculosis.

How similar studies have performed: Related molecular and biophysical studies have led to useful drug targets in other bacteria, though applying single-molecule and kinetic approaches to Mtb transcription factors is relatively novel.
