Drug discovery is a long process in which only a few successful new therapeutic discoveries are made and identification of drug target candidate proteins requires considerable time and efforts. However, the accumulation of information on drugs has made it possible to devise new computational methods for classifying drug target candidates. In this paper, we devise a Drug Target Protein (DT-P) classification method by the summation of weighted features which is extracted from known DT-P. The method is validated using Bayesian decision theory and SVM, and it was revealed to achieve high specificity of 89.5% with 88% accuracy.

The global surge in the population of people 60 years and older, including that in China, challenges healthcare systems with rising age-related diseases. To address this demographic change, the Aging Biomarker Consortium (ABC) has launched the X-Age Project to develop a comprehensive aging evaluation system tailored to the Chinese population. Our goal is to identify robust biomarkers and construct composite aging clocks that capture biological age, defined as an individual's physiological and molecular state, across diverse Chinese cohorts.

Dysfunction of parvalbumin-expressing interneurons (PV-INs) in the cerebral cortex has been implicated in major depressive disorder. Perineuronal nets (PNNs), which encapsulate PV-INs, are considered to influence the structural and functional properties of PV-INs. Semaphorin 3A (Sema3A) is a secreted protein constituent of PNNs, but the specific roles of Sema3A in modulating PV-INs during stress remain unknown.

Spinal muscular atrophy (SMA) is a neurodegenerative disease caused by ubiquitous deficiency in the SMN protein. The identification of disease modifiers is key to understanding pathogenic mechanisms and broadening the range of targets for developing SMA therapies that complement SMN upregulation. Here, we report a cell-based screen that identified inhibitors of p38 mitogen-activated protein kinase (p38 MAPK) as suppressors of proliferation defects induced by SMN deficiency in mouse fibroblasts.

Antibody-drug conjugates (ADCs) are effective targeted therapeutics but are limited in their ability to incorporate less-potent payloads, varied drug mechanisms of action, different drug release mechanisms and tunable drug-to-antibody ratios. Here we introduce a technology to overcome these limitations called 'antibody-bottlebrush prodrug conjugates' (ABCs). An ABC consists of an IgG1 monoclonal antibody covalently conjugated to the terminus of a compact bivalent bottlebrush prodrug that has payloads bound through cleavable linkers and polyethylene glycol branches.

Many pharmaceutical targets partition into biomolecular condensates, whose microenvironments can significantly influence drug distribution. Nevertheless, it is unclear how drug design principles should adjust for these targets to optimize target engagement. To address this question, we systematically investigated how condensate microenvironments influence drug-targeting efficiency.
