Sorafenib (SRF) presents undesirable effects in clinical treatment, due to the lack of targeting, poor water solubility, and obvious side effects. In this study, we constructed a novel nanodrug carrier system for accurate and efficient delivery of SRF, improving its therapeutic effects and achieving tumor-specific imaging. The hollow mesoporous MnO
2
(H-MnO
2
) nanoparticles equipped with target substance aptamers (APT) on the surface were used to load SRF for the first time. The resulting H-MnO
2
-SRF-APT could specifically bound to glypican-3 (GPC3) receptors on the surface of hepatocellular carcinoma (HCC), rapidly undergoing subsequent degradation under decreased pH conditions in the tumor microenvironment (TME) and releasing the loaded SRF. In this process, Mn
2+
ions were used for T
1
-weighted magnetic resonance imaging simultaneously. The
in vitro
cell experiments indicated that H-MnO
2
-SRF-APT showed much more effects on the inhibition in the proliferation of Huh7 and HepG2 HCC cells than that of the non-targeted H-MnO
2
-SRF and free SRF. Besides, the
in vivo
results further confirmed that H-MnO
2
-SRF-APT could effectively inhibit the growth of xenograft tumors Huh7 in the naked mouse with good biosafety. In conclusion, H-MnO
2
-SRF-APT could significantly enhance the therapeutic effect of SRF and is expected to be a new way of diagnosis and treatment of HCC.
Spinal cord injury (SCI) often leads to permanent paraplegia; therefore, it represents a major global health priority. 1,2 Immediately following a spinal trauma, the breakdown of the blood-spinal cord barrier causes an influx of immune cells and proinflammatory cytokines, such as TNFα and IL-1β, into the spinal cord, which triggers an inflammatory cascade. 3 This inflammation eventually unbalances
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.
