Thyroid hormone receptor interactor 13 (TRIP13) is a crucial regulator of the spindle apparatus checkpoint and double-stranded break repair. The abnormal expression of TRIP13 was recently found in several human cancers, whereas the role of TRIP13 in the development of bladder cancer (BCa) has not been fully elucidated. Here, we reported that TRIP13 expression was elevated in BCa tissues compared with normal bladder tissues. Notably, the increased expression of TRIP13 was correlated with advanced tumor stage, lymph node metastasis, distant metastasis and reduced survival in BCa patients. Knockdown of TRIP13 in bladder cancer cells suppressed proliferation, induced cell cycle arrest, promoted apoptosis, and impaired cell motility, ultimately inhibiting tumor xenograft growth. Mechanistic investigations revealed that TRIP13 directly bound to epidermal growth factor receptor (EGFR), modulating the EGFR signaling pathway. Furthermore, TRIP13 expression was positively correlated with EGFR expression in BCa specimens, and the high expression of both TRIP13 and EGFR predicted poor survival. Overall, our results underscore the crucial role of TRIP13 in the tumorigenesis of BCa and provide a novel biomarker and therapeutic target for BCa treatment.
This paper presents a new control methodology based on active disturbance rejection control (ADRC) for designing the tension decoupling controller of the unwinding system in a gravure printing machine. The dynamic coupling can be actively estimated and compensated in real time, which makes feedback control an ideal approach to designing the decoupling controller of the unwinding system. This feature is unique to ADRC. In this study, a nonlinear mathematical model is established according to the working principle of the unwinding system. A decoupling model is also constructed to determine the order and decoupling plant of the unwinding system. Based on the order and decoupling plant, an ADRC decoupling control methodology is designed to enhance the tension stability in the unwinding system. The effectiveness and capability of the proposed methodology are verified through simulation and experiments. The results show that the proposed strategy not only realises a decoupling control for the unwinding system but also has an effective antidisturbance capability and is robust.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
