Butterfly‐Shaped Guest Molecules Enable Tunable Room‐Temperature Phosphorescence in Host‐Guest Doped Systems

open access: yesAdvanced Science, EarlyView.
Butterfly‐shaped triphenylamine‐based guest molecules (DBDBD) doped into rigid host matrices (TPP, CA) achieve efficient, multicolor‐tunable room‐temperature phosphorescence (RTP). The host‐guest synergy enables ultralong afterglow (up to 4 s) and quantum yields (Φp = 3.42%), with applications in dynamic anti‐counterfeiting and information encryption ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

open access: yesHepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...
