Timeline
Welcoming Krishnan to the lab!
New preprint available at Research Square
Our last preprint is available on Research Square. We have used luminescent reporter strains to show robust leaderless translation in M. tuberculosis during optimal growth and conditions of stress.

Farewell to Beth
We wish Beth all the best in her new position. Thanks for your hard work and commitment over the years, we will miss you!

Postdoc position available!
We are looking for a postdoctoral research fellow to join the lab and work on the selective capture of mycobacterial ribosomes.
Closing date is 7th February 2021
Beth talks about using technology for effective teaching
Here is a link to the blog Beth wrote for the Biochemical Society reviewing their e-course on using technology for effective teaching. Enjoy!
Our last preprint on ribosome profiling is now available at bioRxiv
We have further addressed translational regulatory mechanisms that may ensure the adaptation and survival of M. tuberculosis in the host by performing the first ribosome profiling experiment in the virulent strain H37Rv.

Farewell to Anna
We wish Anna the best of luck in her new position.
Thanks for your hard work and commitment, we will miss you!
Great collaborative work on antibiotic resistance evasion in M. tuberculosis just published in Nature Communications
Very happy to see this great work led by Luiz Pedro Carvalho from the Francis Crick Institute finally out.
Getting to the bottom as to why there are almost no recorded cases of tuberculosis becoming resistant to the antibiotic D-Cycloserine.
New collaborative paper on transcriptomic profiling of MTB lineages just published in Nature Communications
So happy to see this work co-led with Iñaki Comas from the IBV-CSIC in Spain finally out in Nature Communications.
Integration of transcriptomes and methylomes from MTB lineages reveals that creation of new transcriptional start sites due to single points mutations is shaping the transcriptional landscape within the MTB complex.
Anna and Beth attend the European Society of Mycobacteriology Congress
From 30th June to 3rd July 2019, Anna and Beth attended the European Society of Mycobacteriology in Valencia, Spain.
Anna described her work, Adaptation through diversity, in an oral presentation, whilst Beth presented a poster entitled, Exploring mechanisms of translation in the human pathogen, Mycobacterium tuberculosis
Beth attends Ribosome 2019
In January 2019, Beth travelled to Mexico to attend the Ribosome Structure and Function 2019, where she presented a poster
Our review about translational regulation in mycobacteria is out in Nucleic Acids Research
In this Review, we highlight important differences in the translational machinery of M. tuberculosis compared with E. coli, and also consider the role of leaderless translation in the ability of M. tuberculosis to establish latent infection and look at the experimental evidence that translational regulatory mechanisms operate in mycobacteria during stress adaptation.

Invited speaker at the Changing views of translation, Royal Society meeting
I have been invited to speak at the Royal Society Meeting: Changing views of translation. I will be talking about Translational control of adaptive responses in Mycobacteria. I can’t wait!
Beth Sawyer brings science to the #BriSciFest2018
Beth and a team of volunteers from UCL, Reading and LSHTM took science to the streets of Brighton this weekend with a hands-on activity about the role of scientists in sport at #BriSciFest2018.
“To coincide with the Winter Olympics, we ran a stall about the science behind performance-enhancing drugs: what they are, their effects, side-effects and how they are detected. Over 200 people visited the stall and worked through the activities to catch the #dirtydopers. Thanks to the @BiochemSoc and @RoyalSocBio for funding and the opportunity to get involved in promoting molecular bioscience in this way.”
PhD studentship available
PhD studentship available within the MRC London Intercollegiate Doctoral Training Partnership (MRC LID) between The London School of Hygiene and Tropical Medicine (LSHTM) and St. George’s University of London (SGUL)
The PhD Project title is “Using functional genomics to understand the manipulation of host cell responses during Mycobacterium tuberculosis infection” and will be supervised by Dr. Axel Nohturfft (primary supervisor – SGUL), Prof. Steve Goodbourn (SGUL) and Dr. Teresa Cortes (LSHTM). Deadline for applications is on Sunday 14th January.
More information about the project and application process can be found here
Beth Sawyer gets the LSHTM small grant scheme in public engagement
Congratulations to Beth for securing funding for her public engagement project ” Secret Agents 005“!
In collaboration with scientists from UCL, she will take science to the streets to inspire primary school children that careers in science are fun and within their reach.
New paper out in Scientific Reports
Our work ” Delayed effects of transcriptional responses in Mycobacterium tuberculosis exposed to nitric oxide suggest other mechanisms involved in survival” has been published in Scientific Reports.
We have challenged M. tuberculosis with nitric oxide and interrogated the dynamic transcriptome and proteome response through time resolved analysis. Our findings suggest that whilst the early transcriptome changes might contribute to late-stage recovery, the initial resistance and survival of M. tuberculosis to nitric oxide is contingent on mechanisms other than transcriptional regulation.
