Advanced Science, EarlyView.This work establishes a novel method for generating multicellular liver organoids from control and MASH donor iPSCs. The model recapitulates several disease‐specific characteristics, with MASH donor‐derived organoids showing higher susceptibility. Lipidomic profiling of MASH organoids closely resembles MASH liver biopsies.

Advanced Science, EarlyView.Phylogenetic and biochemical analyses of the heme transporter CydDC reveal its functional conservation throughout bacterial evolution and demonstrate its unique asymmetric allosteric mechanism. Furthermore, impairment of CydDC function directly affects bacterial antibiotic resistance and likely compromises antibiotic efficacy through drug efflux.

Frontiers in Chemistry, 2019 Tuberculosis is still one of the top 10 causes of deaths worldwide, especially with the emergence of multidrug-resistant tuberculosis. Rifampicin, as the most effective first-line antituberculosis drug, also develops resistance due to the mutation on ...

Molecular basis of rifampicin resistance in Haemophilus influenzae [PDF]
Journal of Antimicrobial Chemotherapy, 2003 To determine the molecular basis of rifampicin resistance in Haemophilus influenzae.Mutations in the rifampicin-resistance determining region of the rpoB gene of H. influenzae were analysed by gene amplification and sequencing in 12 rifampicin resistant, one intermediate and four susceptible isolates.All clinical resistant isolates except one had at ...

Advanced Science, EarlyView.Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

Inhibition of rifampicin‐resistant RNA synthesis by rifampicin—RNA polymerase complexes
FEBS Letters, 1974 Biochemical and electron microscopic evidence has shown that Escherichia coli RNA polymerase holoenzyme forms in vitro, in the absence of nucleoside triphosphates, a stable and specific complex with bacteriophage T7 DNA in the early promoter region of the chromosome [ 1,2].

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Animal Research and One Health, EarlyView.vvrr1, a small RNA, post‐transcriptionally represses the transcriptional regulator LeuO, which directly inhibits the VarS/VarA two‐component system. This triggers a Csr cascade that relieves LuxO repression, ultimately modulating exopolysaccharide production to control biofilm formation and virulence in Vibrio alginolyticus.

British Journal of Clinical Pharmacology, EarlyView.Levofloxacin is a widely used antibiotic included in rifampicin‐resistant tuberculosis (RR‐TB) treatment. Data describing levofloxacin concentrations in breastmilk and infant exposure are limited. We analysed data from two South African studies of breastfeeding women receiving levofloxacin (750–1000 mg daily) for RR‐TB.
