Summary: CRISPR-Cas9-based genome editing technologies have the potential for clinical translation, but delivering nucleic acids into target cells in vivo is challenging. This study presents a new method using focused ultrasound targeted microbubble destruction to deliver CRISPR-Cas9 base editing vectors to the mouse liver. The results demonstrate successful base editing in mouse liver cells, but with lower specificity and more off-target base exchange in vivo.

Summary: Glaucoma is a progressive disease caused by the death of retinal ganglion cells and axonal loss in the optic nerve. Elevated intraocular pressure is a major risk factor contributing to this condition. Current management mainly focuses on lowering intraocular pressure, but it does not address optic nerve degeneration. Gene therapy, especially non-viral delivery systems, shows promise in controlling genes involved in glaucoma pathophysiology and providing neuroprotection.

Summary: Osteosarcoma is a highly invasive and deadly cancer that often occurs in children and adolescents. The overexpression of PLK1 gene in tumors promotes cancer cell proliferation and transformation, making it a therapeutic target for osteosarcoma. However, current RNA interference-based therapies lack a safe and efficient nonviral gene vector. In this study, biodegradable and CO2-derivative cationic poly(vinylcyclohexene carbonates) (CPCHCs) were used as gene vectors for siPLK1 therapeutic strategy in osteosarcoma treatment. Among them, CPCHC60 showed excellent performance in gene transfection efficiency, endo-lysosome escaping, biodegradability, and biosafety. The treatment with CPCHCs/siRNA nanoparticles significantly down-regulated the expression level of PLK1 gene in osteosarcoma cells, leading to cell arrest and apoptosis, resulting in significant tumor regression both in vitro and in vivo. This study provides new insights into the development of superior nonviral gene vectors for cancer treatment and holds high potential for translational nanomedicine applications.

Summary: In this study, a multifunctional non-viral vector was constructed for efficient delivery of CRISPR/Cas9 plasmid. The vector actively targeted tumor cells and delivered the cargo into cell nuclei, resulting in genome editing effects. By disrupting the MTH1 gene, the growth of non-small cell lung cancer was inhibited, promoting cell apoptosis in tumor tissue and reducing liver metastasis.

Summary: The use of nanomaterials in cancer therapy can address the limitations of conventional therapies by utilizing nanotechnology to overcome chemoresistance, radio-resistance, and lack of specific tumor targeting. Cyclodextrins (CDs) are amphiphilic cyclic oligosaccharides that can be synthesized from natural sources and have shown increasing potential in improving solubility and bioavailability of bioactive compounds and therapeutics for cancer treatment. CDs are widely used in drug and gene delivery for cancer therapy, improving anti-proliferative and anticancer effects through targeted delivery and enhanced accumulation at the tumor site.

Summary: The overall success in launching discovered drugs is restricted by the high rate of late-stage failures. Reliable methods are needed to predict the effectiveness and toxicity of medicines early in the drug development process. Modern in vitro disease models and advanced technology, such as 3D bioprinting, can be used to expedite drug discovery. 3D bioprinting has the potential to revolutionize pharmaceutical studies and improve gene delivery and tissue engineering.

Summary: Gene therapy using siRNA has gained much attention for its unique mechanism of action, non-toxicity, and good tolerance, allowing for targeted killing of cancer cells without harming healthy tissues. Compared to traditional treatments, siRNA therapy has fewer side effects and can provide long-term and even curative effects. It has also shown promise in the treatment of cardiovascular diseases, gastrointestinal diseases, and hepatitis B.

Summary: Idiopathic pulmonary fibrosis (IPF) is a chronic and progressive lung disease with a high mortality rate. The commercially available pharmaceuticals show some effects but more effective therapeutics are urgently needed. Gene therapy, using non-viral vectors, is a promising strategy for the treatment of IPF. The non-viral vectors, such as liposomes, polymers, and proteins/peptides, are highlighted for their low immunogenicity and good biocompatibility.

Summary: The study evaluated drug absorption to the PDMS device and investigated the drug responsiveness of human hepatocytes cultured in the PDMS device. The absorption rates of different compounds to the PDMS device were measured and found to be correlated with their octanol/water distribution coefficient values. Furthermore, the hepatocyte-chips were used to examine the response to drugs typically used to evaluate hepatic functions.

Summary: Regardless of the PLGA type with different lactic/glycolic acid ratios, microspheres prepared via the solid-in-oil-in-water (S/O/W) method showed a much higher encapsulation efficiency (EE) and faster drug release compared to microspheres prepared via the co-solvent method. Preparation methods, pH of the aqueous phase, and volume of the aqueous phase were the most influencing parameters on the EE. Confirmation experiment results indicated a 5.76 db increase in signal-to-noise ratio from the initial condition. Minocycline release was fastest with PLGA (50:50) microspheres, followed by PLGA (75:25) and PLGA (85:15).

Summary: Type 2 ryanodine receptor (RYR2) is a cardiac Ca2+ release channel that is associated with catecholaminergic polymorphic ventricular tachycardia (CPVT). This study demonstrates that CPVT mutations lower the threshold [Ca-2(+)](ER) for spontaneous Ca-2(+) release by enhancing the [Ca-2(+)](cyt)-dependent activity of RYR2, without modulating the [Ca-2(+)](ER) sensitivity of RYR2.

Summary: Recently, liver-on-a-chip models have gained increasing attention for pharmacokinetics and toxicity screenings. Researchers have found that perfluoropolyether (PFPE) elastomer, a chemically repellent material, could be an alternative to the commonly used polydimethylsiloxane (PDMS) material in microfluidic devices. The PFPE devices showed improved cell performance with increased production of albumin and urea, as well as enhanced metabolic activity of hepatocytes under dynamic flow conditions compared to static conditions. Although PFPE devices still exhibited some sorption, they demonstrated better chemical repellency and may provide better performance in ADMET evaluation than PDMS devices.

Summary: We demonstrate the potential use of Blautia coccoides JCM1395(T) as a tumor-targeted live bacterial therapeutic. We developed a reliable quantitative analysis method for bacterial detection in biological tissues, overcoming the hindrance caused by the thick outer layer of peptidoglycans in Gram-positive bacteria. Using this method, we individually detected Blautia coccoides JCM1395(T) and Bacteroides vulgatus JCM5826(T) in tumors of mice receiving intravenous mixture injection. This simple and reproducible method, without genetic modification, can be applied to explore a wide range of bacterial species.

Summary: This review discusses the current status and challenges of applying machine-learning techniques to the analysis and prediction of pharmacokinetic data. While traditional mathematical models have limitations in explaining ADME processes and predicting pharmacokinetic time profiles, machine learning offers a data-driven approach for handling complex phenomena. Machine-learning models generally outperform linear models and new structures, such as transfer learning and generative adversarial networks, are continuously being proposed. The key issue now is how to apply these emerging machine-learning technologies to the field of pharmacokinetics/pharmacodynamics.
