Abstract
Transposons, as non-viral integration vectors, provide a secure and efficient method for stable gene delivery. In this study, we have discovered Mage (MG), a novel member of the piggyBac(PB) family, which exhibits strong transposability in a variety of mammalian cells and primary T cells. The wild-type MG showed a weaker insertion preference for near genes, transcription start sites (TSS), CpG islands, and DNaseI hypersensitive sites in comparison to PB, approaching the random insertion pattern. Utilizing in silico virtual screening and feasible combinatorial mutagenesis in vitro, we effectively produced the hyperactive MG transposase (hyMagease). This variant boasts a transposition rate 60% greater than its native counterpart without significantly altering its insertion pattern. Furthermore, we applied the hyMagease to efficiently deliver chimeric antigen receptor (CAR) into T cells, leading to stable high-level expression and inducing significant anti-tumor effects both in vitro and in xenograft mice models. These findings provide a compelling tool for gene transfer research, emphasizing its potential and prospects in the domains of genetic engineering and gene therapy.

Abstract
Transposons are mobile genetic elements that can move to a different position within a genome or between genomes. They have long been used as a tool for genetic engineering, including transgenesis, insertional mutagenesis, and marker excision, in a variety of organisms. The piggyBac transposon derived from the cabbage looper moth is one of the most promising transposon tools ever identified because piggyBac has the advantage that it can transpose without leaving a footprint at the excised site. Applying the piggyBac transposon to precise genome editing in plants, we have demonstrated efficient and precise piggyBac transposon excision from a transgene locus integrated into the rice genome. Furthermore, introduction of only desired point mutations into the target gene can be achieved by a combination of precise gene modification via homologous recombination-mediated gene targeting with subsequent marker excision from target loci using piggyBac transposition in rice. In addition, we have designed a piggyBac-mediated transgenesis system for the temporary expression of sequence-specific nucleases to eliminate the transgene from the host genome without leaving unnecessary sequences after the successful induction of targeted mutagenesis via sequence-specific nucleases for use in vegetatively propagated plants. In this review, we summarize our previous works and the future prospects of genetic engineering with piggyBac transposon.

Evaluation of Nonviral piggyBac and lentiviral Vector in Functions of CD19chimeric Antigen Receptor T Cells and Their Antitumor Activity for CD19 + Tumor Cells. Front Immunol 2022; 12:802705.

Abstract
Nonviral transposon piggyBac (PB) and lentiviral (LV) vectors have been used to deliver chimeric antigen receptor (CAR) to T cells. To understand the differences in the effects of PB and LV on CAR T-cell functions, a CAR targeting CD19 was cloned into PB and LV vectors, and the resulting pbCAR and lvCAR were delivered to T cells to generate CD19pbCAR and CD19lvCAR T cells. Both CD19CAR T-cell types were strongly cytotoxic and secreted high IFN-γ levels when incubated with Raji cells. TNF-α increased in CD19pbCAR T cells, whereas IL-10 increased in CD19lvCAR T cells. CD19pbCAR and CD19lvCAR T cells showed similar strong anti-tumor activity in Raji cell-induced mouse models, slightly reducing mouse weight while enhancing mouse survival. High, but not low or moderate, concentrations of CD19pbCAR T cells significantly inhibited Raji cell-induced tumor growth in vivo. These CD19pbCAR T cells were distributed mostly in mesenteric lymph nodes, bone marrow of the femur, spleen, kidneys, and lungs, specifically accumulating at CD19-rich sites and CD19-positive tumors, with CAR copy number being increased on day 7. These results indicate that pbCAR has its specific activities and functions in pbCAR T cells, making it a valuable tool for CAR T-cell immunotherapy.

Nishizawa‐Yokoi A, Toki S. A piggyBac-mediated transgenesis system for the temporary expression of CRISPR/Cas9 in rice. PLANT BIOTECHNOLOGY JOURNAL 2021; 19:1386-1395. [PMID: 33529430 PMCID: PMC8313132 DOI: 10.1111/pbi.13559] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Accepted: 01/27/2021] [Indexed: 05/03/2023]
Abstract
Targeted mutagenesis via CRISPR/Cas9 is now widely used, not only in model plants but also in agriculturally important crops. However, in vegetative crop propagation, CRISPR/Cas9 expression cassettes cannot be segregated out in the resulting progenies, but must nevertheless be eliminated without leaving unnecessary sequences in the genome. To this end, we designed a piggyBac-mediated transgenesis system for the temporary expression of CRISPR/Cas9 in plants. This system allows integration into the host genome of piggyBac carrying both CRISPR/Cas9 and positive selection marker expression cassettes from an extrachromosomal double-stranded transfer DNA (dsT-DNA), with subsequent excision of the transgenes by the re-transposition of piggyBac from the host genome after successful induction of targeted mutagenesis via CRISPR/Cas9. Here, we demonstrate that the transgenesis system via piggyBac transposition from T-DNA works to deliver transgenes in rice. Following positive-negative selection to exclude transgenic cells randomly transformed with T-DNA, piggyBac-mediated transgenesis from the extrachromosomal dsT-DNA was successful in ca. 1% of transgenic callus lines. After temporary expression of CRISPR/Cas9 within piggyBac, we confirmed, in a proof-of-concept experiment, that piggyBac could be excised precisely from the genome via the stably transformed transposase PBase. Even after excision of piggyBac, CRISPR/Cas9-induced targeted mutations could be detected in the endogenous gene in regenerated rice plants. These results suggest that our piggyBac-mediated transgenesis system will be a valuable tool in establishing efficient CRISPR/Cas9-mediated targeted mutagenesis in vegetatively propagated crops.

Abstract
Transposons are mobile genetic elements evolved to execute highly efficient integration of their genes into the genomes of their host cells. These natural DNA transfer vehicles have been harnessed as experimental tools for stably introducing a wide variety of foreign DNA sequences, including selectable marker genes, reporters, shRNA expression cassettes, mutagenic gene trap cassettes, and therapeutic gene constructs into the genomes of target cells in a regulated and highly efficient manner. Given that transposon components are typically supplied as naked nucleic acids (DNA and RNA) or recombinant protein, their use is simple, safe, and economically competitive. Thus, transposons enable several avenues for genome manipulations in vertebrates, including transgenesis for the generation of transgenic cells in tissue culture comprising the generation of pluripotent stem cells, the production of germline-transgenic animals for basic and applied research, forward genetic screens for functional gene annotation in model species and therapy of genetic disorders in humans. This review describes the molecular mechanisms involved in transposition reactions of the three most widely used transposon systems currently available (Sleeping Beauty, piggyBac, and Tol2), and discusses the various parameters and considerations pertinent to their experimental use, highlighting the state-of-the-art in transposon technology in diverse genetic applications.
