BACKGROUND
The development of effective treatments against metastatic cancers, including breast cancer, is among the most important challenges in current experimental and clinical cancer research. We recently demonstrated that Walterinnesia aegyptia venom (WEV), either alone or in combination with
Untargeted delivery as well as low efficacy are two main obstacles for effective breast cancer therapy. Here in this study, we surface modified silica nanoparticles (SLN) with Trastuzumab (Tra) to construct a tumor-targeting carrier (Tra-SLN) for specific drug delivery to human epidermal growth
Tamoxifen administration enhanced overall disease-free survival and diminished mortality rates in cancer patients. However, patients with breast cancer often fail to respond for tamoxifen therapy due to the development of a drug-resistant phenotype. Functional analysis and molecular studies suggest
Multimodal contrast agents with low toxicity and targeted modification have opened up new possibilities for specific imaging of breast cancer and shown broad application prospects in biomedicine and great potential for clinical transformation. In this work, a potential multifunctional Triple negative breast cancer (TNBC) is the most aggressive and lethal subtype of breast cancer. It is associated with a very poor prognosis and intrinsically resistant to several conventional and targeted chemotherapy agents and has a 5-year survival rate of less than 25%. Because the treatment
Silica nanowires have great potential for usage in the development of highly sensitive in vivo biosensors used for biomarker monitoring. However, careful analysis of nanowire toxicity is required prior to placing these sensors within the human body. This paper describes a real-time and quantitative
A novel dual-target recognition sandwich strategy for selective capture and detection of MCF-7 breast cancer cells based on core-shell magnetic mesoporous silica (Fe3O4@nSiO2@mSiO2@apt) nanoparticles was developed. Fe3O4@nSiO2@mSiO2@apt nanoparticles, which were prepared by a layer-by-layer method
Breast cancer accounted for 15 per cent of total cancer deaths in female patients in 2010. Although significant progress has been made in treating early-stage breast cancer patients, there is still no effective therapy targeting late-stage metastatic breast cancers except for the conventional
OBJECTIVE
In this article, we use an alternative cancer model for the evaluation of nanotherapy, and assess the impact of surface functionalization and active targeting of mesoporous silica nanoparticles (MSNPs) on therapeutic efficacy in vivo.
METHODS
We used the chorioallantoic membrane xenograft
OBJECTIVE
Mutations in the p53 tumor suppressor gene are one among the most common genetic abnormalities to be described in breast cancer. However, there are a few recant reports on non-viral vector-mediated p53 gene delivery in breast cancer.
METHODS
A new formulation of luminescent silica
Spherical silica nanoparticles (SNP) have been synthesized and functionalized with anti-HER-2 scFv800E6 antibody by both localized histidine-tag recognition, leading to an oriented protein ligation, and glutaraldehyde cross-linking, exploiting a statistical reactivity of lysine amine groups in the
Mucin-1 (MUC1), a transmembrane glycoprotein is aberrantly expressed on ~90% of breast cancer and is an excellent target for nanoparticulate targeted imaging. In this study, the development of a dye-doped NIR emitting mesoporous silica nanoparticles platform conjugated to tumor-specific MUC1
Triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype. In the last years, navitoclax has emerged as a possible treatment for TNBC. Nevertheless, rapid navitoclax resistance onset has been observed thorough Mcl-1 overexpression. As a strategy to overcome Mcl-1-mediated
A novel folic acid functionalized terbium-doped dendritic fibrous nanoparticle (Tb@KCC-1-NH2 -FA) with high surface area was synthesized using a novel hydrothermal protocol. In the present work, we report the fluorescent Tb-doted nanomaterial with emission wavelength at 497 nm which
Normal micelle microemulsion method was utilized for fabrication of organically modified silica (ORMOSIL) nanoparticles. The void and dye-doped nanoparticles were synthesized in nonpolar core of two different surfactants including Aerosol OT and Tween 80. The nanoparticles were characterized using
