It is currently challenging to eradicate cancer. In the case of solid tumors, the dense and aberrant extracellular matrix (ECM) is a major contributor to the heterogeneous distribution of small molecule drugs and nano-formulations, which makes certain areas of the tumor difficult to treat. As such, much research is devoted to characterizing this ma...

Viruses have recently emerged as promising nanomaterials for biotechnological applications. One of the most important applications of viruses is phage display, which has already been employed to identify a broad range of potential therapeutic peptides and antibodies, as well as other biotechnologically relevant polypeptides (including protease inhi...

Hypoxia can induce chemoresistance, which is a significant clinical obstacle in cancer therapy. Here, we assessed development of hypoxia-induced chemoresistance (HICR) against free versus polymeric cisplatin micelles in a triple negative breast cancer cell line, MDA-MB-231. We then explored two strategies for the modulation of HICR against cisplati...

The finding that hypoxia can induce cancer stemness in various experimental models is in agreement with the conceptual basis of cancer cell plasticity. Here, we aimed to gain insights into the molecular basis of hypoxia-induced cancer cell plasticity in triple negative breast cancer (TNBC). To achieve this goal, we employed our previously published...

Purpose: Silibinin, is a natural compound, which has shown anticancer activity in various malignancies. In this study, we evaluated the anticancer effects of silibinin in B16-F10 melanoma cells and developed a novel thermoresponsive hydrogel for local delivery of this compound. Method: A thermoresponsive hydrogel loaded with silibinin was prepar...

Hypoxia-induced chemoresistance (HICR) is a well-recognized phenomenon, and in many experimental models, hypoxia inducible factor-1α (HIF-1α) is believed to be a key player. We aimed to better understand the mechanism underlying HICR in a triple negative breast cancer cell line, MDA-MB-231, with a focus on the role of HIF-1α. In this context, the e...

Stereoregularity of polymers is known to influence their physicochemical and functional properties in the bulk form. Recent studies have also provided evidence for the effect of polymer stereoregularity on the physicochemical and functional properties of their self-assembled nanostructures. Research in this area has witnessed a relatively rapid pac...

To circumvent the problem of burst drug release from polymeric micelles, we designed three layered ABC micelles consisting of methoxy poly(ethylene oxide) (PEO) as the shell layer (A block); poly(lactic acid) (PLA) of different stereo-chemistries as the outer core (B block) and poly(α-benzylcarboxylate-ε-caprolactone) (PBCL) or poly(ε-caprolactone)...

In this study, doxorubicin (DOX) was conjugated to a lipophilic triphenylphosphonium (TPP) that is selectively taken up by mitochondria membrane of cells. This new derivative of DOX, i.e., TPP-DOX, was characterized by Infrared Spectroscopy (IR), Nuclear Magnetic Resonance (1H-NMR, 13C-NMR) and Mass Spectrometry. The effect of TPP modification on D...

To investigate the effect of polymerization method on the stability and drug release properties of polymeric micelles formed using stereo-active block copolymers. Diblock copolymers consisting of methoxy poly ethylene oxide (MePEO) and poly(lactide)s (PLA)s of different stereochemistry were synthesized by bulk or solution polymerization. Polymers a...
