A helium burst biolistic device adapted to penetrate fragile insect tissues

Journal of Insect Science, 2001
To compensate for the extremely low penetration efficiency of the original PDS/1000-He Bio Rad biolisticreg; device and the deleterious blast effect, design modifications have been made to the launching module.

Efficient Transfection of Large Plasmids Encoding HIV-1 into Human Cells—A High Potential Transfection System Based on a Peptide Mimicking Cationic Lipid

Pharmaceutics, 2020
One major disadvantage of nucleic acid delivery systems is the low transfection or transduction efficiency of large-sized plasmids into cells. In this communication, we demonstrate the efficient transfection of a 15.5 kb green fluorescent protein (GFP ...

Activation of interferon regulatory factor-3 via toll-like receptor 3 and immunomodulatory functions detected in A549 lung epithelial cells exposed to misplaced U1-snRNA [PDF]

, 2009
U1-snRNA is an integral part of the U1 ribonucleoprotein pivotal for pre-mRNA splicing. Toll-like receptor (TLR) signaling has recently been associated with immunoregulatory capacities of U1-snRNA.

RIPK4 function interferes with melanoma cell adhesion and metastasis

Molecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Associação entre proteínas do plasma seminal, motilidade e viabilidade espermática em coelhos submetidos a doping genético Association among seminal plasma proteins, sperm motility and sperm viability in rabbits submitted to gene doping

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2013
Neste trabalho foi estudada a correlação entre o perfil proteico do plasma seminal e a motilidade e viabilidade espermática em coelhos submetidos ao tratamento com vetores de expressão contendo o gene da eritropoetina (EPO) e com EPO recombinante humana.

Transfection by Electroporation [PDF]

Current Protocols in Cell Biology, 1992
AbstractElectroporation–the use of high‐voltage electric shocks to introduce DNA into cells–can be used with most cell types, yields a high frequency of both stable transformation and transient gene expression, and, because it requires fewer steps, can be easier than alternate techniques.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

Molecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Effect of Recombinant Plasmid pEGFP-AFP-hTNF on Liver Cancer Cells (HepG2 Cells) in vitro when Delivered by PEG-PEI/Fe3O4 Nanomagnetic Fluid

Journal of the Formosan Medical Association, 2011
Gene delivery into liver cancer cells has been a problem. This study aimed to understand the effect of using PEGI/Fe3O4 nanomagnetic fluid as a gene vector for liver cancer gene therapy.

Magnetofection potentiates gene delivery to cultured endothelial cells [PDF]

, 2003
Modification of cellular functions by overexpression of genes is increasingly practised for research of signalling pathways, but restricted by limitations of low efficiency. We investigated whether the novel technique of magnetofection (MF) could enhance

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.
