Abstract Chemotherapeutic efficacy plays a significant role in the development of nanotheranostic systems for drug delivery in tumor cells. In this study, we demonstrate the self-assembly of C225 conjugate, Perfluorohexane/Gold Nanoparticles (Au-PFH-NPs), which results in low-intensity focused ultrasound diagnosis ablation of thyroid cancer treatment. Cetuximab-Conjugated Perfluorohexane/Gold Nanoparticles (C-Au-PFH-NPs) showed excellent stability in water, PBS, and 20% rat serum. Transmission electron microscopy images revealed the effective construction of C-Au-PFH-NPs with commonly spherical assemblies. The incubation of C625 thyroid carcinoma with C-Au-PFH-NPs triggered apoptosis, which was confirmed by flow cytometry analysis. The C-Au-PFH-NPs showed remarkable antitumor efficacy in human thyroid carcinoma xenografts. The histopathological results additionally confirm the achieved outcomes. Furthermore, we successfully examined the efficiency of C-Au-PFH-NPs when using the thyroid carcinoma low-intensity focused ultrasound (LIFUS) diagnostic imaging in vivo. These findings are clear for LIFUS agents with high performing images. It is also identified that different therapeutic purposes will have extensive potential for future biomedical purposes.

Abstract Background Despite the use of aggressive multimodality treatment, most anaplastic thyroid carcinoma (ATC) patients die within a year of diagnosis. Although the combination of BRAF and MEK inhibitors has recently been approved for use in BRAF-mutated ATC, they remain effective in a minority of patients who are likely to develop drug resistance. There remains a critical clinical need for effective systemic agents for ATC with a reasonable toxicity profile to allow for rapid translational development. Methods & Methods Twelve human thyroid cancer cell lines with comprehensive genomic characterization were used in a high-throughput screening (HTS) of 257 compounds to select agents with maximal growth inhibition. Cell proliferation, colony formation, orthotopic thyroid models, and patient-derived xenograft models (PDX) were used to validate the selected agents. Results Seventeen compounds were effective and docetaxel, LBH-589, and pralatrexate were selected for additional in vitro and in vivo analysis as they have been previously approved by the FDA for other cancers. Significant tumor growth inhibition (TGI) was detected in all tested models treated with LBH-589; pralatrexate demonstrated significant TGI in the orthotopic papillary thyroid carcinoma model and two PDX models; docetaxel demonstrated significant TGI only in the context of mutant TP53. Conclusions HTS identified classes of systemic agents which demonstrate preferential effectiveness against aggressive thyroid cancers, particularly those with mutant TP53. Preclinical validation in both orthotopic and PDX models, which are accurate in vivo models mimicking tumor microenvironment, may support initiation of early phase clinical trials in non-BRAF mutated or refractory to BRAF/MEK inhibition ATC.

Abstract Chemotherapeutic efficacy can be significantly developed nanotheranostics systems of drug delivery in tumor cells. In this work, we have demonstrated that the self-assembled by C225 conjugates Au-PFH-NPs (C-Au-PFH-NPs) for low intensity focused ultrasound diagnosis ablation of thyroid cancer treatment. C-Au-PFH-NPs have shown excellent stability in water, PBS and 20% rat serum. Transmission electron microscopy (TEM) images also exposed the effective construction of C-Au-PFH-NPs with commonly spherical sized assemblies. The incubation of the C625 thyroid carcinoma with C-Au-PFH-NPs triggers apoptosis, which was confirmed by the flowcytometry analysis. The C-Au-PFH-NPs, with remarkably displays the potent antitumor efficacy in a human thyroid carcinoma xenografts. A histopathological result reveals that precisely achieved to additional confirm these outcomes. Further, we successfully examined the efficiency of C-Au-PFH-NPs when used the thyroid carcinoma low intensity focused ultrasound diagnosis imaging (LIFUS) in vivo. These findings clearable for LIFUS agents with high performing image and different therapeutic purpose will have extensive possible for the future biomedical purposes.

Characteristic Features

One of the most characteristic features of cancer cells is their ability to metastasia. It is suggested that the modifications of the structure and properties of cancer cells surfaces play the main role in this process. The present work was aimed at finding out what ultrastructural features apear in tumor in vivo which removal of individual cancer cells from the cell population can provide. For this purpose the cellular interactions in the normal human thyroid and cancer tumor of this gland electron microscopic were studied. The tissues were fixed in osmium tetroxide and were embedded in Araldite-Epon.In normal human thyroid the most common type of intercellular contacts was represented by simple junction formed by the parallelalignment of adjacent cell membranees leaving in between an intermembranes space 15-20 nm filled with electronlucid material (Fig. 1a). Sometimes in the basal part of cells dilatations of the intercellular space 40-50 nm wide were found (Fig. 1a). Here the cell surfaces may form single short microvilli.
