Folate-conjugated Dol-poly(D,L-lactic acid)-b-poly (ethylene glycol)-folate (Dol-PLA-PEG-FA), was synthesized from dodecanol-poly(D,L-lactic acid), amino-terminated poly(ethylene glycol) and folate. (1)H NMR proved the successful synthesis of Dol-PLA-PEG-FA. Nanoparticles (NPs) were further
Cancer stem cells are speculated to have the capability of self-renewal and re-establishment of tumor heterogeneity, possibly involved in the potential relapse of cancer. CD44+CD24-/lowESA+ cells have been reported to possess tumorigenic properties, and these biomarkers are thought to be highly
BACKGROUND
Drug-induced myopathy is a serious side effect that often requires removal of a medication from a drug regimen. For most drugs, the underlying mechanism of drug-induced myopathy remains unclear. Monocarboxylate transporters (MCTs) mediate L-lactic acid transport, and inhibition of MCTs
Cancer chemotherapy can benefit from the combination of different anticancer drugs. Here, we prepared doxorubicin (Dox)- and thioridazine (Thio)-coloaded methoxy poly(ethylene glycol)-poly(l-lactic acid) (MPEG-PLA) nanoparticles (NPs) for breast cancer therapy. These NPs have an average particle
Anti-oestrogens (AEs) are currently used for treating hormone-dependent breast cancers. They specifically bind to oestrogen receptors (ERs) and inhibit their transactivation capacity. However, ERs are present in various other tissues in which AEs may have either a beneficial or detrimental action.
Despite advances in polymeric nanoparticles (NPs) as effective delivery systems for anticancer drugs, rapid clearance from blood and poor penetration capacity in heterogeneous tumors still remain to be addressed. Here, a dual coating of poly (ethylene glycol)-poly (d,l-lactic acid) (PEG-PDLLA) and
The interpretation of the local microenvironment of the extracellular matrix for malignant tumor cells is in intimate relation with metastatic spread of cancer cells involving the associated issues of cellular proliferation and drug responsiveness. This study was aimed to assess the combination of
PURPOSE
Bortezomib (BTZ) is a proteasome inhibitor used for multiple myeloma and mantle cell lymphoma treatment. BTZ's aqueous in solubility is the main hindrance in its successful development as a commercial formulation. The main objective of the present study is to develop and
Combination chemotherapy with time-programmed administration of multiple drugs is a promising method for cancer treatment. However, realizing time-programmed release of combined drugs from a single carrier is still a great challenge in enhanced cancer therapy. Here, an implantable trilayer
Poly(ethylene glycol)-block-poly(d,l-lactic acid) (PEG-b-PLA) micelles affect drug solubilization, and a paclitaxel (PTX) loaded-PEG-b-PLA micelle (PTX-PM) is approved for cancer treatment due to injection safety and dose escalation (Genexol-PM®) compared to Taxol®. However, PTX-PM is unstable in
This study was carried out to assess the therapeutic efficacy and toxicity of tamoxifen (Tmx) loaded poly(d,l-lactic acid) (PLA) nanoparticles (Tmx-NPs) for breast cancer. An in vivo study was conducted to determine the effect of Tmx-NPs on DMBA induced mammary tumor in female Wistar rat. The
In this work, docetaxel (DTX) was encapsulated in monomethoxy poly(ethylene glycol)-poly(ε-caprolactone) (mPEG-PCL) micelles and monomethoxy poly(ethylene glycol)-poly(D, L-lactic acid) (mPEG-PLA) micelles, respectively. For the further application, the acute/genetic toxicity evaluation and
β-Lapachone (LPC) is a novel cytotoxic agent that is bioactivated by NADP(H): quinone oxidoreductase 1 (NQO1), an enzyme elevated in a variety of tumors, such as non-small cell lung cancer (NSCLC), pancreatic cancer, liver cancer, and breast cancer. Despite its unique mechanism of action, its
We have developed a parenteral delivery system for the administration of the highly promising pure antiestrogen RU 58668 (RU). Two types of nanoparticles (NP) made of biodegradable copolymers and coated with polyethylene-glycol (PEG) chains were prepared: nanospheres (NS) (diameter, approximately
The stromal tissue surrounding most carcinomas is comprised of an extracellular matrix densely packed with collagen-I fibers, which are often highly aligned in metastatic disease. Here we developed an in vitro model to test the effect of an aligned fibrous environment on cancer cell morphology and
