Figure Lengend Snippet: Validation of novel TDMD triggers. ( A ) Schematic of trigger site deletion (Δts) strategy to validate putative TDMD triggers. ( B , D ) Genomic organization of TDMD trigger transcripts with conservation and predicted miRNA base-pairing architecture of the trigger sites. Nucleotides predicted to base-pair with the miRNA are shown in bold. ( C , E ) qRT-PCR analysis of indicated miRNAs, relative to miR-16-5p, in WT and Δts MEFs. Parental MEFs or two independent Δts clones for each trigger site were infected with lentivirus expressing Cas9 and a nontargeting CRISPR guide (sgNT) or Zswim8- targeting guide (sg Zswim8 ). Values were normalized to expression level in sg Zswim8 for each condition. n = 3 technical replicates per clone, with individual data points plotted (mean ± SD shown). P -values were calculated by one-tailed Student's t -test. (*) P < 0.05, (**) P < 0.01, (***) P < 0.001, (****) P < 0.0001. ( F ) qRT-PCR analysis of the indicated miRNAs, relative to U6, in NIH3T3 cells at time points after serum starvation and restimulation. NIH3T3 cells expressing dCas9-KRAB were infected with lentivirus encoding a nontargeting guide (sgNT) or guides targeting Plagl1 or Lrrc58 . Parental NIH3T3 cells were infected with lentivirus expressing Cas9 and a nontargeting guide (sgNT) or Zswim8- targeting guide (sg Zswim8 ). Values were normalized to expression at the 0 h time point for each condition. n = 3 technical replicates per condition, with mean ± SD shown. P -values were calculated by one-tailed Student's t -test comparing sg Plagl1 (dCas9-KRAB) or sg Lrrc58 (dCas9-KRAB) with sgNT (dCas9-KRAB) or comparing sg Zswim8 (Cas9) with sgNT (Cas9). (*) P < 0.05.

Article Snippet: HEK293T and NIH3T3 cells were obtained from ATCC, and immortalized MEFs were generated previously by transfecting primary MEFs with a plasmid expressing SV40 large T antigen ( ).

Article Title: Structure Elucidation, Biosynthesis and Biological Evaluation of Neosorangicin A, a Member of the Sorangicin Family

doi: 10.64898/2026.01.26.701680

Figure Lengend Snippet: Intracellular activity of sorangicins against S. aureus Newman in A549 ( A ) and NIH 3T3 ( B ) cells. At 1.75 hours post infection, cells were washed once and treated with different concentrations of rifampicin (RIF), sorangicin A (SorA), neosorangicin A (NeoSorA), or with 0.1% ( v/v ) methanol (control) in the presence of 10 µg mL −1 gentamicin. Reduction of bacterial burden was evaluated 24 hours post infection by CFU (colony-forming unit) counting. Limit of detection (LoD) is 10 1 CFU. Horizontal lines represent mean values of at least three independent biological experiments. Statistical analysis was performed by one-way ANOVA with Dunnett’s multiple comparison test. p < 0.05: *, p < 0.0001: ****.
