Mitochondriopathy inspired adenosine triphosphate(ATP) depletions have been recognized as a powerful way for controlling tumor growth. Nevertheless, selective sequestration or exhaustion of ATP under complex biological environments remains a prodigious challenge. Harnessing the advantages of in vivo self-assembled nanomaterials, we designed an Intracellular ATP Sequestration(IAS) system to specifically construct nanofibrous nanostructures on the surface of tumor nuclei with exposed ATP binding sites,leading to highly efficient suppression of bladder cancer by induction of mitochondriopathy-like ***, the reported transformable nucleopeptide(NLS-FF-T) self-assembled into nuclear-targeted nanoparticles with ATP binding sites encapsulated inside under aqueous conditions. By interaction with KPNA2. the NLS-FF-T transformed into a nanofibrous-based ATP trapper on the surface of tumor nuclei,which prevented the production of intracellular energy. As a result, multiple bladder tumor cell lines(T2.,EJ and RT-112. revealed that the half-maximal inhibitory concentration(IC50) of NLS-FF-T was reduced by approximately 4-fold when compared to NLS-T. Following intravenous administration, NLS-FF-T was found to be dose-dependently accumulated at the tumor site of T2. xenograft mice. More significantly, this IAS system exhibited an extremely antitumor efficacy according to the deterioration of T2. tumors and simultaneously prolonged the overall survival of T2. orthotopic xenograft mice. Together, our findings clearly demonstrated the therapeutic advantages of intracellular ATP sequestration-induced mitochondriopathy-like damages, which provides a potential treatment strategy for malignancies.

On equivalence of state-based potential games

science China(Information sciences) 2024年第6期67卷 313-327页

作者： Han wu Jinhuan wang institute of mathematics School of ScienceHebei University of Technology

In this paper, we explore state-based potential games using the semi-tensor product of ***, applying the potential equation, we derive both a necessary and sufficient condition as well as a sufficient condition to verify whether a state-based game qualifies as a potential game. Next, we present two static equivalence conditions of state-based potential games. We then delve into dynamic equivalence. We propose a criterion that allows us to identify state-based games that are dynamically equivalent to state-based potential games and share similar dynamic properties. Ultimately, we introduce the concept of state-based networked evolutionary games. We provide a necessary and sufficient condition to ensure that a state-based networked evolutionary game can be classified as a state-based potential game.
