Rules, for what can be a good drug, are extremely valuable in #DrugDiscovery. Nevertheless, it seems like once in a while all of these rules need to be thrown out of the window as exemplified by Nibrozetone that is investigated in Phase III for cancer treatment. drughunter.com/molecule/rrx...

nibrozetone

Nibrozetone (RRx-001), identified via a phenotypic screen of compounds from the rocket fuel industry, has been advanced by EpicentRx into multiple clinical trials. The molecule additionally received a...

Function of a protein: something the protein does. Function in maths: a mapping from X to Y. Function in code: re-use code to do a task. Function at a conference: have a drink and look at posters.

1/11 New preprint from the Sternberg lab in collaboration with the Fernández lab! We are excited to share our structure-function study of DRT10, a bacterial defense-associated reverse transcriptase that synthesizes long tandem-repeat DNA.🧵 Read the full story here: www.biorxiv.org/content/10.6...

Mechanism of tandem-repeat DNA synthesis by an antiviral reverse transcriptase

Defense-associated reverse transcriptases (DRTs) employ DNA synthesis to protect bacteria against phage infection[1][1],[2][2]. We previously showed that DRT10, a tripartite system comprising an RT, a...

Who benefits from Fast & Fair peer review? It benefits everybody. It benefits authors because they get a fast and high-quality review. It benefits editors because the editors handling the manuscripts don’t have to spend a lot of time finding reviewers.

Two weeks ago, our FlashPPI paper was published in @pnas.org. Today, we introduce our updated model, FlashPPI2. Fine-tuned on new AlphaFold structures, this new model achieves a 17% improvement over FlashPPI on the E. coli protein interaction benchmark. seqhub.org/blog/flashppi2

FlashPPI2: Enhanced Model, Scaled Across 130,000+ Genomes - SeqHub

FlashPPI2 drives up PPI prediction performance (AUPRC) by 17% while maintaining inference speed at minutes per genome — now deployed across SeqHub's database of over 130,000 microbial genomes.

Lol, a paper that describes my life. My natural reaction to feeling like I'm finally getting the hang of something has always been to drop it and try something else. And somehow I still often feel like I'm not getting out fast enough.

How do we close the diagnostic gap for #Chagas disease? With only about 10% of people diagnosed and 1% receiving care, experts have defined priorities for better rapid & molecular diagnostics and improved access to care. doi.org/10.1186/s128... @bmc.springernature.com

Advancing diagnostics for Chagas disease: key product characteristics and harmonized evaluation strategies - an expert meeting report - BMC Infectious Diseases

Chagas disease is a global public health issue, life-threatening parasitic disease, affecting mostly underserved communities in Latin America. Yet, 10% of infected individuals are diagnosed, and 1% receive etiological treatment. Priority actions for disease elimination by 2030 are streamlining diagnostic methods and evaluating and developing point-of-care diagnostics. We convened 44 researchers, test developers, and health authorities, to provide scientific advice and reach consensus on (i) a harmonized protocol for evaluation of rapid diagnostic tests; (ii) preferred molecular diagnostics characteristics (scope, performance, operational features, pricing, and evaluation standards); and (iii) economic impact evidence needed to have a transformational impact in primary healthcare. We considered global and national perspectives with discordant evidence from multiple disciplines. Our outcomes provide a reference on practical applications and recommendations to promote test development and evaluation. Finally, we debate about the appropriate approach moving forward to meet the diagnostic gap, and propose how investments could be stimulated.

Unreliable and underperforming antibodies are a longstanding problem, so while the reveal of apparently manipulated antibody data in Thermo Fisher's catalog was a shock, the frustration it sparked among many researchers is perhaps no surprise. My reporting:

Science sleuths uncover more than 100 suspicious images in Thermo Fisher antibody catalogue

Scientists have long worried about the reliability of commercial antibodies, and the latest findings have sparked fresh concerns.

Proteins are the machinery of life. Billions of their sequences have been cataloged—but the biology behind most is still unknown. Today we're releasing ESMFold2, ESMC and ESM Atlas to help change that. Open source, open to every scientist. biohub.ai/esm/protein
