The change in transfection efficiency of electroporation by the combined treatment with mild preheating (40 degrees C for 30 min) was investigated. HCT 116, HeLa S3 and SGC 7901 cells were treated with electroporation in medium containing pBKCMV-Luc plasmid with or without preheating. After 24 h, luciferase activity was increased by 36, 28 and 77%; luciferase mRNA transcription was increased by 45, 50 and 68%; and fluorescein isothiocyanate-dextran accumulation was increased by 9, 35 and 15% in preheated groups, respectively. These results demonstrate that the transfection efficiency was enhanced by mild preheating. The mechanism partially involves increased macromolecular particle accumulation.

Biochips are widely applied to manipulate the geometrical morphology of stem cells in recent years. Patterned antenna-like pseudopodia are also probed to explore the influence of pseudopodia formation on gene delivery and expression on biochips. However, how the antenna-like pseudopodia affect gene transfection is unsettled and the underlying trafficking mechanism of exogenous genes in engineered single cells is not announced.

Treatment with autologous chimeric antigen receptor (CAR)-modified T cells can achieve outstanding clinical response rates in heavily pretreated patients with B and plasma cell malignancies. However, relapses occur, and they limit the efficacy of this promising treatment approach. The complex GMP-compliant production and high treatment costs cause that CAR T cells cannot yet be used in a broad population.

Lipid nanoparticle (LNP)-mediated RNA delivery holds significant potential for the treatment of various liver diseases. Ionizable lipids play a crucial role in the formulation of LNPs and directly influence their delivery efficiency. In this study, we introduced an innovative concept by incorporating an ether bond into the hydrophobic tail of ionizable lipids for the first time.

Exogenous genes are inserted into target cells during gene therapy in order to compensate or rectify disorders brought on by faulty or aberrant genes. However, gene therapy is still in its early stages because of its unsatisfactory therapeutic effects which are mainly due to low transfection efficiency of vectors, high toxicity, and poor target specificity. A natural polymer with numerous bioactive sites, good mechanical qualities, biodegradability, biocompatibility, and processability called silk fibroin has gained attention as a possible gene therapy vector.

The bolaform C12(DDUPAC)2 has hydroxyl (OH) functionality at both the cationic head groups. The impact of head group structure on the self-assembly and effectiveness of gene transfection and antimicrobial activity was investigated and compared with that of the hydrochloride salt C12-(N, N-dimethyl-N-(2-ureidoethan-1-aminium chloride)2 (C12(DUAC)2) of its precursor molecule.
