Antibiotic resistance gene mRNA (MRGN-associated mRNA)

MRGN-associated target mRNA refers to the messenger RNA transcripts of antibiotic resistance genes found in Multi-Resistant Gram-Negative (MRGN) bacteria, such as Klebsiella pneumoniae and Pseudomonas aeruginosa. These mRNAs encode enzymes like carbapenemases (e.g., NDM-1, KPC) and extended-spectrum beta-lactamases (ESBLs) that neutralize last-resort antibiotics, posing a severe threat in clinical settings. Modern therapeutic strategies, including mobilizable RNA-guided nucleases (mRGNs) and antisense oligonucleotides, are designed to specifically target and degrade these mRNA sequences to restore antibiotic susceptibility or directly kill the pathogen. By leveraging sequence-specific recognition, these technologies aim to provide a precision medicine approach to treating multidrug-resistant infections while minimizing damage to the host's beneficial microbiome. The development of these 'mRNA-based antibacterials' represents a significant frontier in combating the global rise of antimicrobial resistance.
