    Bio-Rad electroporation instrument
    Overview of the pKD46-Red-mediated scarless deletion of the target gene in S. sonnei ① The pKD46 plasmid (encoding Red recombinase) is pre-transformed into S. sonnei and cells are grown at 30 °C to competence. ② A PCR product containing antibiotic-resistance marker flanked by two FRT sites is amplified from pKD3/pKD4. ③ The targeting fragment is introduced by <t>electroporation;</t> Red-driven homologous recombination and antibiotic selection yield primary recombinants. ④ Cultivation at 42 °C cures the temperature-sensitive pKD46. ⑤ Introduction of the CP20 plasmid (encoding FLP recombinase) excises the resistance cassette between the FRT sites; a second 42 °C heat step eliminates CP20, leaving a clean, marker-free deletion mutant. H1/H2, homology extensions; P1/P2, primer sites; FRT, FLP recognition target. The figure is reprinted with permission from Wang et al., 2025. Created with BioRender.

    Identification of the interaction between CRP and YdeH using the BACTH system Both crp and ydeH were cloned and inserted into the pUT18C and pKNT25 vectors, respectively, and co-transformed into the BTH101 strain by electroporation. The positive clones were spotted together with the negative control and positive control on the colour plate. Finally, the colour development of the plate was checked.

    Article Snippet: Currently, glioma treatment is limited by two main factors: timely detection at onset or relapse and restriction of drugs by the blood–brain barrier (BBB) from entering the brain and influencing tumor growth.. However, a safe BBB-traversing drug delivery system has brought new hope to glioma treatment.. Exosomes have strong cargo-loading capacity and have the ability to cross the BBB.

    Article Snippet: Background The combined restoration of tumor-suppressive microRNAs (miRs) has been identified as a promising approach for inhibiting breast cancer development.. This study investigated the effect of the combined restoration of miR-424-5p and miR-142-3p on MCF-7 cells and compared the efficacy of the combined therapy with the monotherapies with miR-424-5p and miR-142-3p.. Methods After transfection of miR-424-5p and miR-142-3p mimics into MCF-7 cells in the combined and separated manner, the proliferation of tumoral cells was assessed by the MTT assay.
