Ultrasonically controlled albumin-conjugated liposomes for breast cancer therapy.

In this study, pegylated (stealth) liposomes conjugated to human serum albumin (HSA) were investigated for the delivery of a model drug (calcein) to breast cancer cells. The fluorescent results showed that calcein uptake by the two breast cancer cell lines (MDA-MB-231 and MCF-7) was significantly higher with the HSA-PEG liposomes compared to the non-targeted control liposomes. Furthermore, the exposure to low-frequency ultrasound (LFUS) resulted in a statistically significant uptake of calcein compared to the uptake without ultrasound. The described drug delivery (DD) system, which involves combining the targeted liposomal formulation with ultrasonic triggering techniques, promises a safe, effective and site-specific breast cancer therapy.

ConclusionSolely regarding sensitivity of AUS, our study could show significant differences between biological subtypes of breast cancer with lower sensitivity in Luminal patients. While PPV was excellent, standing for a low overtreatment rate using AUS for clinical decision making, sensitivity was poor overall, comparable to the results of other studies.

Abstract Stimuli-responsive drug-delivery nanocarriers (DDNs) have been increasingly reported in the literature as an alternative for breast cancer therapy. Stimuli-responsive DDNs are developed with materials that present a drastic change in response to intrinsic/chemical stimuli (pH, redox and enzyme) and extrinsic/physical stimuli (ultrasound, light, magnetic field and electric current). In addition, they can be developed using different strategies, such as functionalization with signaling molecules, leading to several advantages, such as (a) improved pharmaceutical properties of liposoluble drugs, (b) selectiv...

Authors: Salkho NM, Paul V, Kawak P, Vitor RF, Martins AM, Al Sayah M, Husseini GA Abstract A new modality of drug targeting to tumors has been proposed. The ligand-mediated approach, that already increases the therapeutic index of the drug, can still be optimized by the encapsulation of the drug into sonosensitive nanoparticles. In this work, an endogenous ligand, estrone, was used to synthesize doxorubicin-encapsulating liposomes for estrogen receptor (ER)-positive breast cancer therapy with cyanuric chloride (2,4,6 trichloro-1,3,5 triazine) being used as a linking molecule to attach 3-OH group of estrone to the ...

In this study, we firstly proposed an accessible top-down approach using ultrasound method to prepare nanoMIL-100 and secondly, evaluated its potentials as an anticancer nanocarrier. This is the first report that docetaxel (DTX) as a highly hydrophobic anticancer drug was encapsulated in nanoMIL-100 with the drug payload of 57.2 wt%. Characterizations of the prepared nanoMIL-100 and DTX-loaded nanoMIL-100 were performed by PXRD, FT-IR, N2 adsorption, DLS and FE-SEM. Moreover, the drug loading and release processes were quantified by HPLC. The in vitro release of DTX from the prepared nanocarrier was investigated in ...

Abstract Ultrasound-responsive nanodroplets are a class of new emerging smart drug delivery systems which provide image-guided nano-therapy of various diseases, especially cancers. Here, we developed multifunctional smart curcumin-loaded chitosan/perfluorohexane nanodroplets for contrast-ultrasound imaging and on-demand drug delivery. The nanodroplets were synthesized via nanoemulsion process. The optimal formulation with the size of 101.2nm and 77.8% curcumin entrapment was chosen for release study and cytotoxicity evaluation. Sonication at the frequency of 1MHz, 2W/cm(2) for 4min triggered the release of 63.5% o...

Abstract MicroRNAs (miRNAs), as a novel class of small noncoding RNAs, have been identified as important transcriptional and posttranscriptional inhibitors of gene expression. Ultrasound‐targeted microbubble destruction (UTMD) is a noninvasive method for microRNA delivery. We aimed to investigate the effect of UTMD of miR‐133a on breast cancer treatment. It has been reported that miRNA‐133a is involved in various cancers. miR‐133a was lowly expressed in breast cancer tissues and breast cancer cell lines MCF‐7 and MDA‐MB‐231. The miR‐133a expression was significantly upregulated under exogenous miRNA‐133a ...
