Drug Discovery News The great escape: tumour cell plasticity in resistance to targeted therapy Review Article | 10 October 2019 The success of targeted therapies in cancer treatment has been impeded by various mechanisms of resistance. Besides the acquisition of resistance-conferring genetic mutations… Read More Targeting mRNA processing as an anticancer strategy Review Article | […]

Nature Communications: Retinitis pigmentosa (RP) patients may benefit from AAV mediated gene therapy

Detail Introduction: Retinitis pigmentosa (RP) characterized as retina degeneration is one of the major causes for inherited blindness, which can occur in one of four thousand babies. Most of RP show rod photoreceptor dysfunctions induced by gene mutations, which can further trigger loss of cone photoreceptors and then result in blindness. To date, there is […]

Nature Communication: No immunogenicity! Can the spring of AAV mediated gene therapy be far behind?

Detail Introduction: Recombinant adeno-associated virus (AAV) vectors exhibit promising outcomes on gene therapy with its durable expression in the targeting tissues. Even so, in most cases, AAV immunogenicity still represents a major limitation for its clinical trials. Recently, a research team from Sorbonne Université and INSERM U974 (France) has employed an effective means to avoid […]

Cancer gene therapy: Dual-vector prodrug activator gene therapy displays synergistic cytocidal effects on cancer

Detail Introduction:Retroviral replicating vectors (RRVs) has been proved as an excellent gene therapy vector to achieve efficient gene transduction. To date, more than 499 clinical trials have been carried out using lentivirus vectors for gene delivery and promising gene therapy outcomes have been achieved in a variety of diseases, mostly in cancer. Today, a dual-vector […]

Nature Communications: AAV mediated gene targeting in vivo through CRISPR-Cas9 repressors

Detail Introduction: CRISPR-Cas9 system is a widely used tool to perform genetic editing. In recent years, this technology has been well developed. Specifically, deactivated nuclease-null Cas9 (dCas9) together with guide RNA (gRNA) can be utilized to convey various transcriptional or epigenetic modulators to the target site to regulate gene expression. One of these modulators is […]

Atrial-Specific Gene Delivery Using an AAV Vector

Detail Introduction: Atrial diseases pose a major threaten to human health. Recently Ni L et al established an atrial-specific genetic manipulation system based on AAV (adeno-associated virus) vectors, which facilitates the pathogenesis study of atrial diseases and provides a powerful genetic tool for gene therapy study. The correlated findings were published in the journal of […]

Deamidation of Amino Acids on the Surface of AAV Capsids Leads to Charge Heterogeneity and Altered Vector Function

Detail Introduction: As an excellent gene therapy vector, AAV has been widely used for the treatment of many diseases, such as retinal dystrophy, cystic fibrosis, Duchenne Muscular Dystrophy, Hemophilia. However, post-translational modification of the AAV capsids and how they affect vector activity is poorly understood during the development of AAV vectors into pharmaceutical products. Recently, […]

Correction of half the cardiomyocytes fully rescue Friedreich Ataxia mitochondrial cardiomyopathy

Detail Introduction: Friedreich ataxia (FA) is a rare, neurodegenerative, autosomal recessive disease, characterized by spinocerebellar and sensory ataxia, including diabetes and cardiac hypertrophy, which is a major medical concern in FA, responsible for 59% of premature death of patients. FA is mainly caused by a (GAA)n expansion within the 1st intron of the frataxin gene […]

AAV CRISPR editing rescues cardiac and muscle function for 18 months in dystrophic mice

Detail Introduction: Duchenne muscular dystrophy (DMD), caused by out-of-frame mutations of dystrophin gene, is a progressive degenerative disease resulting in cardiac and smooth muscle dysfunction in approximately 250–300,000 boys and young men worldwide. Previous studies showed that AAV-delivered CRISPR gene editing tools can reframe the mutated dystrophin gene and restore dystrophin expression in vitro and […]

A dual-AAV approach rescues auditory function in deaf otoferlin knock-out mice

Detail Introduction: Around one in 1000 newborns are suffered from congenital disabling hearing loss, among which, mutations in OTOF gene (encoding otoferlin protein) accounting for 2.3–10% of patients, and over one thousand pathogenic mutations have been identified within this gene. Therefore, a postnatal supplement of otoferlin cDNA into the inner ear might be a promising […]
