6-thioguanine inhibits EV71 replication by reducing BIRC3-mediated autophagy.

Background: Enterovirus 71 (EV71) is one of the major causative agents of hand, foot, and mouth disease (HFMD), and can cause severe cerebral complications and even fatality in children younger than 5 years old. However, there is no specific medication for EV71 infection in clinical practice. Our previous studies had identified the 6-thioguanine (6-TG), an FDA-approved anticancer drug, as a potential antiviral agent, but its anti-EV71 activity is largely unknown, therefore, we aim to explore the antiviral effect of 6-TG on EV71.

Serum starvation induces cytosolic DNA trafficking via exosome and autophagy-lysosome pathway in microglia.

The imbalance of microglial homeostasis is highly associated with age-related neurological diseases, where cytosolic endogenous DNA is also likely to be found. As the main medium for storing biological information, endogenous DNA could be localized to cellular compartments normally free of DNA when cells are stimulated. However, the intracellular trafficking of endogenous DNA remains unidentified.

Enhancing immunotherapy efficacy in oral cancer through AKB-9778-mediated vascular normalization.

Tumor vasculature exhibit numerous abnormal features distinct from those of healthy vessels, potentially advancing tumor development by establishing an aberrant microenvironment. Therefore, vascular normalization has proven to be an effective tactic for substantially enhancing treatment efficacy across multiple tumors. However, the methods to attain vascular normalization may vary among tumor types.

Baicalein-loaded porous silk fibroin microspheres modulate the senescence of nucleus pulposus cells through the NF-κB signaling pathway.

Intervertebral disc degeneration (IVDD), an age-associated degenerative condition, significantly contributes to low back pain, thereby adversely affecting individual health and quality of life, while also imposing a substantial societal burden. Baicalein, a natural flavonoid derived from Scutellaria baicalensis Georgi, demonstrates a range of pharmacological activities, including antioxidant, anti-inflammatory, anti-tumor, and antibacterial properties. This positions it as a promising candidate for the treatment of IVDD through intradiscal drug delivery.
