Introduction The development of nanodrug carriers utilizing tumor microenvironment has become a hotspot in reversing multidrug resistance (MDR). Materials and methods This study synthesized a redox-sensitive copolymer, Pluronic F127-disulfide bond-d-α-tocopheryl polyethylene glycol 1000 succinate (FSST), through the connection of the reduction-sensitive disulfide bond between F127 and d-α-toc...

Multidrug resistance (MDR) remains a major challenge for providing effective chemotherapy for many cancer patients. To address this issue, we report an intelligent polymer-based drug co-delivery system which could enhance and accelerate cellular uptake and reverse MDR. The nanodrug delivery systems were constructed by encapsulating disulfiram (DSF), a P-glyco-protein (P-gp) inhibitor, into the ...

Cerebral malaria (CM) is a severe complication of and a leading cause of death due to Plasmodium falciparum infection. CM is likely the result of interrelated events, including mechanical obstruction due to parasite sequestration in the microvasculature, and upregulation of Th1 immune responses. In parallel, blood-brain-barrier (BBB) breakdown and damage or death of microglia, astrocytes, and n...

Recently, specific attention has been paid to aptamers, short DNA or RNA, as a tool for cancer diagnosis and therapy. In the present study MCS nanogels were prepared by Myristate: Chitosan at 1:9 ratio and were characterized by several techniques. A selected ssDNA aptamer (Apt) capable of detecting LNCaP cells was linked to Myristilated Chitosan nanogels (Apt-MCS) by glutaraldehyde and loaded w...

Abstract Gestational trophoblastic tumors seriously endanger child productive needs and the health of women in childbearing age. Nanodrug-based therapy mediated by transporters provides a novel strategy for treatment tumors. Focusing on overexpression human equilibrative nucleoside transporter 1 (ENT1) membrane choriocarcinoma cells (JEG-3), cytarabine (Cy, substrate ENT1)-grafted liposomes (Cy...
