Exposing bacteria to antibiotics can accelerate the emergence of AMR and spread of antibiotic-resistant bacteria . Under the antibiotic stimulus, bacterial SOS responses can be activated for self-saving .
抗菌素诱导的细菌中ARG基因的水平转移:Mini Review - 知乎
Beaber等人61发现,SOS反应介导了抗生素诱导的HGT。SOS反应由LexA(SOS阻遏物)和RecA(SOS诱导物)蛋白质控制。RecA的辅蛋白酶活性促进LexA蛋白的自切割,导致SOS反应的诱导(图4)。

2024年5月16日 · Furthermore, we demonstrate that as a potent inhibitor of the mutagenic SOS response, OXF-077 suppresses the rate of ciprofloxacin resistance emergence in S. aureus. This work supports SOS-response inhibitors as a novel means to combat AMR, and delivers OXF-077 as a tool molecule for future development.
Molecular Mechanisms of Antimicrobial Resistance
Understanding the underlying molecular basis of antimicrobial resistance (AMR) is pertinent to develop new drugs or design appropriate strategies to prevent the emergence of resistance. The present chapter is a ready reckoner for the mode of action of antibiotics, mechanism of AMR, and transfer of its resistance.

A tale of two plasmids: contributions of plasmid associated …
2022年8月3日 · Dissemination of antimicrobial resistance (AMR) genes by horizontal gene transfer (HGT) mediated through plasmids is a major global concern. Genomic epidemiology studies have shown varying success of different AMR plasmids during outbreaks, but the underlying reasons for these differences are unclear.
硼酸衍生物抑制分枝杆菌中 LexA 介导的 SOS 反应,bioRxiv
几种病原体的抗菌素耐药性(amr)特性是全球关注的主要问题之一,需要不断创新才能得到控制。 由 LexA 和 RecA 调节的细菌 SOS 反应通过有利的突变促进 AMR。
