The Double Nickase Plasmid features a U6 promoter for sgRNA expression, a 20 nt targeting sequence, and a gRNA scaffold to guide Cas9n. It includes a CBh promoter for Cas9n (D10A) and puromycin resistance, GFP for transfection verification, and nuclear localization signals (NLS). The 2A peptide allows co-expression of Cas9n and Puro from a single promoter, enabling precise genome editing with reduced off-target effects.

Cas9n Nickase gRNA Plasmid Targeting: Dual gRNA plasmids create single-strand nicks at precise DNA sequences for efficient genome editing using Cas9n Nickase.
This image illustrates the Cas9n Nickase mechanism used for precise genome editing. Two plasmids (Plasmid 1 and Plasmid 2) are shown, each containing a targeted DNA sequence. The system utilizes single-guide RNAs (sgRNA) to direct Cas9n Nickase to specific genomic locations, represented by the blue and pink DNA strands. The sgRNA scaffold aids in guiding Cas9n to the 20 nucleotide (nt) target sequence on the DNA. Cas9n makes single-strand cuts at NCC and NGG sites, enabling precise gene modifications without creating double-strand breaks.

Lasp1 编码 LIM and SH3 protein 1(LASP-1),这是一种与肌动蛋白结合的适配蛋白,富集于黏着斑、片状伪足和膜褶皱等结构,在这些部位帮助协调细胞骨架重塑与细胞运动。通过与肌动蛋白相关蛋白及信号复合体的相互作用,LASP-1 参与黏附动态调控、迁移以及与细胞外基质结合相关的力学信号转导通路。在小鼠体系中,Lasp1 的功能常在上皮–间质样行为、创伤修复和组织重塑等情境下研究,因为这些过程中黏附与侵袭程序的变化尤为显著。LASP-1 的表达与定位改变已在多种与疾病相关的模型中与迁移失调及增殖信号异常相关联,因此它可作为研究细胞骨架调控与类转移表型的重要节点。
