Cover Story: Illustrated is the concept of aptamer siRNA chimeras – AsiCs, therapeutic RNAs that specifically knock down disease-associated genes in malignant cells. AsiCs bind through their aptamer part (red) to a specific target molecule on a malignant cell, and enter the cell cytosol by endocytosis where they are recognized by the RNAi machinery. As a result, messenger-RNA molecules matching the siRNA of the AsiC will be cleaved, leading to a reduced expression of the related gene (e.g. an oncogene). View this paper

Aptamer Cell-Based Selection: Overview and Advances

  • Silvia Catuogno and
  • Carla Lucia Esposito

Aptamers are high affinity single-stranded DNA/RNA molecules, produced by a combinatorial procedure named SELEX (Systematic Evolution of Ligands by Exponential enrichment), that are emerging as promising diagnostic and therapeutic tools. Among select...

Comparison of Liver Detargeting Strategies for Systemic Therapy with Oncolytic Adenovirus Serotype 5

  • Tien V. Nguyen,
  • Mary E. Barry,
  • Mallory A. Turner,
  • Catherine M. Crosby,
  • Miguel A. Trujillo,
  • John C. Morris and
  • Michael A. Barry

Oncolytic viruses would ideally be of use for systemic therapy to treat disseminated cancer. To do this safely, this may require multiple layers of cancer specificity. The pharmacology and specificity of oncolytic adenoviruses can be modified by (1)...
