Roles of oolong tea extracts in the protection against Staphylococcus aureus infection in Caenorhabditis elegans.

Oolong tea, a popular traditional Chinese tea, possesses various bioactivities, but little is known about its roles in the protection against pathogens, such as Staphylococcus aureus, in vivo. This study investigated the roles of the water-soluble oolong tea extracts (OTE) on S. aureus infection in Caenorhabditis elegans, a promising model to study the host-microbe interactions in vivo.

The maintenance of skeletal muscle quality involves various signal pathways that interact with each other. Under normal physiological conditions, these intersecting signal pathways regulate and coordinate the hypertrophy and atrophy of skeletal muscles, balancing the protein synthesis and degradation of muscle. When the total rate of protein synthesis exceeds that of protein degradation, the muscle gradually becomes enlarged, while when the total rate of protein synthesis is lower than that of protein degradation, the muscle shrinks.

Insulin-like growth factor 2 (IGF2) is a mitogenic peptide hormone expressed by various tissues. Although it is three times more abundant in serum than IGF1, its physiological and pathological roles are yet to be fully understood. Previous transcriptome sequencing studies have shown that IGF2 expression is increased in hypertrophic scar (HS); however, its role in HS formation and the underlying mechanism remains elusive.

Human pluripotent stem cell-derived β-cells (SC-β-cells) represent an alternative cell source for transplantation in diabetic patients. Although mitogens could in theory be used to expand β-cells, adult β-cells very rarely replicate. In contrast, newly formed β-cells, including SC-β-cells, display higher proliferative capacity and distinct transcriptional and functional profiles.

Among women, breast cancer is one of the most prevalent cancers. The disease has a complex etiology, with multiple biological pathways contributing to its development. As insulin signaling has mitogenic effects, glucose is a necessary cellular metabolic substrate, and the growth and metastasis of breast cancer are closely related to cellular glucose metabolism.
