Trpv4-mediated apoptosis of Leydig cells induced by high temperature regulates sperm development and motility in zebrafish.

Exposure of testes to high-temperature environment results in defective spermatogenesis. Zebrafish exposed to high temperature exhibited apoptosis not only in germ cells but also in Leydig cells, as expected from studies using mice or salmon. However, the role of testicular somatic cells in spermatogenesis defects remains unclear.

Efficient visible/NIR light-driven uncaging of hydroxylated thiazole orange-based caged compounds in aqueous media.

In photoactivation strategies with bioactive molecules, one-photon visible or two-photon near-infrared light-sensitive caged compounds are desirable tools for biological applications because they offer reduced phototoxicity and deep tissue penetration. However, visible-light-sensitive photoremovable protecting groups (PPGs) reported so far have displayed high hydrophobicity and low uncaging cross sections ( < 50) in aqueous media, which can obstruct the control of bioactivity with high spatial and temporal precision. In this study, we developed hydroxylated thiazole orange (HTO) derivatives as visible-light-sensitive PPGs with high uncaging cross sections ( ≈ 370) in aqueous solution.

Type 1 diabetes related to immune checkpoint inhibitors.

Type 1 diabetes, in part, has been recently reported as a side effect of immune checkpoint inhibitors (ICIs). The frequency of type 1 diabetes related to ICIs is estimated to be ∼3.5%.
