doi: 10.1038/s42003-025-07893-4

Figure Lengend Snippet: Comparison of SunTag-ePE3 with canonical fused ePE3, Split-ePE3, and MS2-ePE3 at four endogenous loci, including HEK3 locus ( a ), EMX1 locus ( b ), FANCF locus ( c ), and RNF2 locus ( d ) in HEK293T cells. Each locus contains three types of prime editing: nucleotide transversion, insertion, and deletion. Data and error bars indicate the mean and s.d. of three independent biological replicates. Negative controls represent four kinds of PE3 components without pegRNAs. The numbers above the bars represent fold change between different treatment groups.

Article Title: Zipper-interacting protein kinase mediates neuronal cell death and cognitive dysfunction in traumatic brain injury via regulating DEDD

doi: 10.1038/s41419-025-07474-7

Figure Lengend Snippet: A – C Immunoblot analysis of DEDD expression in primary neurons from WT and Zipk +/− mice ( A ), SH-SY5Y cells with ZIPK knockdown ( B ) or overexpression ( C ). D – F DEDD mRNA levels were analyzed by qRT-PCR in WT and Zipk +/− primary neurons ( D ) and SH-SY5Y cells with ZIPK knockdown ( E ) or overexpression ( F ). G HEK293T cells were transiently transfected with HA-vector or HA-ZIPK and Flag-DEDD constructs and subjected to a CHX assay. Representative immunoblot showing DEDD levels at different time points after CHX addition was shown. H SH-SY5Y cells were transiently transfected with HA-vector or HA-ZIPK constructs and then treated with CHX for the indicated duration, followed by immunoblot quantification of DEDD protein levels. NC, negative control. * P < 0.05, ** P < 0.01, *** P < 0.001, ns, not significant. Unpaired two-tailed Student’s t test was used for analysis.

Article Title: A functional SNP of the core promoter region within goat C DC25A gene affects litter size

doi: 10.3389/fvets.2024.1471123

Figure Lengend Snippet: Mechanism diagram. (A) The structure patterns of goat CDC25A gene. (B) The core promoter of goat CDC25A gene was located at position-663 to-237. The electrophoregram on the left displayed that the five fragments were amplified successfully. The bar plots in the middle and on the right displayed the relative luciferase activity of different fragments within CDC25A gene promoter detected in HEK293T and CHO-K1 cells, respectively. (C) One novel SNP (NC_030829.1:g.51731829A > C) within the core promoter of goat CDC25A gene was found, which might change the binding of transcription factors. (D) The novel SNP significantly affected the transcriptional activity of CDC25A gene. (E) Left: associations between the novel SNP and litter size in goat CDC25A gene and the proportion of different types of litter size in individuals with AA, AC and CC genotypes. Right: the proportion of AA, AC and CC genotypes in single-lamb and multi-lamb groups. SBWC goat, Shaanbei white cashmere goat; UTR, untranslated region; CDS, coding sequence; ** p < 0.01. Bars with different letters (a, b, c, d) means p < 0.05.
