During clinical trials, a number of fully characterized molecules are dropped along the way because they do not provide enough benefit for the patient. Some of them show limited side effects and might be of great use for other applications. AS1411 is a nucleolin-targeting aptamer that underwent phase II clinical trials as anticancer agent. Here, we show that AS1411 exhibits extremely potent antiviral activity and is therefore an attractive new lead as anti-HIV agent.

Glutathione (GSH) is a key biomarker closely associated with cancer, and its content varies greatly between normal cells and cancer cells. However, intracellular detection of GSH was challenging because existing probes not only have a long detection time but also have fluorescence in the blue-green region that overlaps with the biological matrix's spontaneous fluorescence, thus affecting the detection accuracy. Therefore, a new red fluorescent nano-probe was needed to rapidly and accurately detected GSH within the biological matrix.

Ovarian cancer (OC) is the most fatal of all gynecological malignancies, presenting a significant threat to women's health. Its treatment is complicated by severe dose-dependent chemotherapy toxicity, drug resistance, and tumor migration. Herein, an intelligent combination strategy of chemotherapy and nucleic acid therapy, named ApMEmiR&D is developed.

Mitochondria-targeted photodynamic therapy (PDT) has emerged as one of the most promising antitumor therapies, as it significantly enhances the efficacy of photosensitizers. An efficient and biocompatible nanocarrier to deliver cationic photosensitizers (PSs) is vital for mitochondria-targeted PDT but still challenging. Herein, a poly-AS1411 aptamer DNA nanoclew (AS-AMD) synthesized via rolling circle amplification (RCA) is developed, incorporating mitochondria-targeted PSs (APNO) and paramagnetic Mn for mitochondria-targeted PDT and magnetic resonance imaging (MRI).

Choroidal neovascularization (CNV) is a leading cause of visual impairment in wet age-related macular degeneration (wAMD). Recent investigations have validated the potential of reducing glutamine synthetase (GS) to inhibit neovascularization formation, offering prospects for treating various neovascularization-related diseases. In this study, we devised a CRISPR/Cas9 delivery system employing the nucleic acid aptamer AS1411 as a targeting moiety and exosome-liposome hybrid nanoparticles as carriers (CAELN).
