Nanoneedle Bio-patch Provides Minimally Invasive Drug Delivery

A flexible bio-patch made from silicon nanoneedles embedded in a thin layer of elastomer was shown to deliver exact doses of biomolecules to cells and tissues while minimizing discomfort to the wearer. More...

Mutation in p53 Suppressor Gene Drives Tumor Development

Cancer researchers have outlined a molecular mechanism that promotes tumor development and growth by interfering with the normal expression of the p53 suppressor gene. More...

Biodegradable Nanoscaffolds Improve Chances for Stem Cell Therapies

The therapeutic potential of biodegradable nanoscaffolds made from manganese dioxide (MnO2) for advanced stem cell transplantation and neural tissue engineering was discussed favorably in a recent paper. More...

In vivo CRISPR/Cas9 Therapy Prevents Arrhythmias in Model

Delivery of the CRISPR/Cas9 gene-editing tool via an adeno-associated viral vector (AAV) directly to heart cells in a mouse model of catecholaminergic polymorphic ventricular tachycardia was found to efficiently and specifically prevent development of arrhythmias. More...

Mechanism Explains Why Damaged DNA Accumulates in ALS Neurons

A team of neurodegenerative disease researchers identified a mechanism that leads to the accumulation of damaged DNA in neurons that characterizes amyotrophic lateral sclerosis (ALS). More...

Immune Sensitivity Hampers Clinical Applications of CRISPR/Cas9

Findings presented in a recent paper suggest that use of the CRISPR/Cas9 gene-editing tool in clinical settings may be more complicated than previously thought, since most people have a pre-existing immune sensitivity to proteins from the bacterial source of Cas9. More...

Image: Pancreatic cancer cells deficient in the expression of the human gene known as Schlafen 11 and resistant to chemotherapy (left panels) were re-sensitized to chemotherapeutic treatment (middle and right panels) by inhibiting the expression of the transfer RNA known as tRNA-Leu-TAA through specially designed antisense oligonucleotides (Photo courtesy of Manqing Li, Michael David Laboratory, University of California, San Diego).

Proposed Treatment Aims to Re-Sensitize Cancer Cells

Cancer cells that lack the Schlafen 11 gene frequently develop resistance to commonly used DNA-damaging (DDA) chemotherapeutic drugs, but recent research suggests that this resistance may be reversible. More...
