ULTRASOUND IN MEDICINE & BIOLOGY 2024; 50:680-689. [PMID: 38311538 DOI: 10.1016/j.ultrasmedbio.2024.01.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 01/03/2024] [Accepted: 01/05/2024] [Indexed: 02/06/2024]
Abstract
OBJECTIVE To explore the effect of ultrasound-stimulated microbubble cavitation (USMC) on enhancing antiangiogenic therapy in clear cell renal cell carcinoma. MATERIALS AND METHODS We explored the effects of USMC with different mechanical indices (MIs) on tumor perfusion, 36 786-O tumor-bearing nude mice were randomly assigned into four groups: (i) control group, (ii) USMC0.25 group (MI = 0.25), (iii) USMC1.4 group (MI = 1.4) (iv) US1.4 group (MI = 1.4). Tumor perfusion was assessed by contrast-enhanced ultrasound (CEUS) before the USMC treatment and 30 min, 4h and 6h after the USMC treatment, respectively. Then we evaluated vascular normalization(VN) induced by low-MI (0.25) USMC treatment, 12 tumor-bearing nude mice were randomly divided into two groups: (i) control group (ii) USMC0.25 group. USMC treatment was performed, and tumor microvascular imaging and blood perfusion were analyzed by MicroFlow imaging (MFI) and CEUS 30 min after each treatment. In combination therapy, a total of 144 tumor-bearing nude mice were randomly assigned to six groups (n = 24): (i) control group, (ii) USMC1.4 group, (iii) USMC0.25 group, (iv) bevacizumab(BEV) group, (v) USMC1.4 +BEV group, (vi) USMC0.25 +BEV group. BEV was injected on the 6th, 10th, 14th, and 18th d after the tumors were inoculated, while USMC treatment was performed 24 h before and after every BEV administration. We examined the effects of the combination therapy through a series of experiments. RESULTS Tumor blood perfusion enhanced by USMC with low MI (0.25)could last for more than 6h, inducing tumor VN and promoting drug delivery. Compared with other groups, USMC0.25+BEV combination therapy had the strongest inhibition on tumor growth, led to the longest survival time of the mice. CONCLUSION The optimized USMC is a promising therapeutic approach that can be combined with antiangiogenic therapy to combat tumor progression.

Abstract
A major limitation of tumor antiangiogenic therapy is the pronounced off-target effect, which can lead to unavoidable injury in multiple organs. Ensuring sufficient delivery and controlled release of these antiangiogenic agents at tumor sites is crucial for realizing their clinical application. Here, we develop a smart DNA-based nanodrug, termed Endo-rDFN, by precisely assembling the antiangiogenic agent, endostar (Endo), into a reconfigurable DNA framework nanotube (rDFN) that could recognize tumor-overexpressed nucleolin to achieve the targeted delivery and controllable release of Endo. Endo-rDFN can not only effectively enhance the tumor-targeting capability of Endo and maintain its efficient accumulation in tumor tissues but also achieve on-demand release of Endo at tumor sites via the specific DNA aptamer for tumor-overexpressed nucleolin, named AS1411. We also found that Endo-rDFN exhibited significant inhibition of angiogenesis and tumor growth, while also providing effective protection against multiorgan injury (heart, liver, spleen, kidney, lung, etc.) to some extent, without compromising the function of these organs. Our study demonstrates that rDFN represents a promising vector for reducing antiangiogenic therapy-induced multiorgan injury, highlighting its potential for promoting the clinical application of antiangiogenic agents.

Abstract
Mechanosensitive ion channels sense mechanical stimuli applied directly to the cellular membranes or indirectly through their tethered components, provoking cellular mechanoresponses. Among others, Piezo1 mechanosensitive ion channel is a relatively novel Ca2+-permeable channel that is primarily present in non-sensory tissues. Recent studies have demonstrated that Piezo1 plays an important role in Ca2+-dependent cell death, including apoptosis and ferroptosis, in the presence of mechanical stimuli. It has also been proven that cancer cells are sensitive to mechanical stresses due to higher expression levels of Piezo1 compared to normal cells. In this review, we discuss Piezo1-mediated cell death mechanisms and therapeutic strategies to inhibit or induce cell death by modulating the activity of Piezo1 with pharmacological drugs or mechanical perturbations induced by stretch and ultrasound.

Abstract
This study aimed to evaluate the effect of dual-frequency sonication in the presence of thalidomide angiogenesis inhibitor and nanomicelles containing doxorubicin on inhibiting the growth and angiogenesis of breast adenocarcinoma in BALB/c female mice. Sixty mice carrying the tumor were divided into 12 groups: (A) control, (B) 28 kHz and 3 MHz sonication, (C) thalidomide, (D) thalidomide and 28 kHz, (E) thalidomide and 3 MHz, (F) thalidomide and dual-frequency sonication, (G) doxorubicin, (H) nanomicelles containing doxorubicin, (I) nanomicelles containing doxorubicin and dual-frequency sonication, (J) thalidomide and doxorubicin, (K) thalidomide and nanomicelles containing doxorubicin, and (L) thalidomide and nanomicelles containing doxorubicin and dual-frequency sonication. The delay in the tumor growth and angiogenesis percent were extracted. Pathological and immunohistochemical studies were performed to confirm the treatment. The findings of tumor growth retardation parameters and animal survival were significantly different in group L from all groups (P < 0.05). The highest rate of inhibition was in group L with a 46% inhibition. In group L, 100% of the animals survived until day 49. In groups F, C, G, B, and A, all the animals survived 45, 42, 39, 32, and 30 days, respectively. Pathological results showed a decrease in tumor grade in groups K and L. Histopathological results demonstrate a decrease in group L angiogenesis compared to group C. These findings were consistent with the results of color Doppler ultrasound imaging. Dual-frequency sonication in the presence of thalidomide and doxorubicin-containing nanomicelles inhibits tumor growth and angiogenesis.

Abstract
Ultrasound (US), as a safe and non-invasive tool, has drawn researchers' attention to treat pancreatic ductal adenocarcinoma (PDAC). Piezo1, a mechanosensitive channel, can be activated by various mechanical stimuli. In this study, we tested the expression of Piezo1 in PDAC cell lines and tissues, and cell apoptosis in vitro and in vivo with siRNA, a lentivirus system, and a subcutaneous xenograft tumor-bearing model under the condition of US with microbubbles (MBs). We found that Piezo1 was highly expressed in PDAC cells; it was activated by US with MBs and was closely related to the apoptosis of PDAC cell lines and tumors. This study highlighted the idea of utilizing the high expression of Piezo1 in PDAC and US with MBs to provide a non-invasive strategy for the treatment of PDAC from the aspect of mechanotransduction. Mechanosensitive channel Piezo1 is highly expressed in pancreatic cancer cells Ultrasound with microbubbles induces apoptosis of pancreatic cancer cells Piezo1 is activated by ultrasound with microbubbles and mediates calcium influx

Abstract
Colon cancer (CC) kills countless people every year throughout the globe. It persists as one of the highly lethal diseases to be treated because the overall survival rate for CC is meagre. Early diagnosis and efficient treatments are two of the biggest hurdles in the fight against cancer. In the present work, we will review thriving strategies for CC targeted drug delivery and critically explain the most recent progressions on emerging novel nanotechnology-based drug delivery systems. Nanotechnology-based animal and human clinical trial studies targeting CC are discussed. Advancements in nanotechnology-based drug delivery systems intended to enhance cellular uptake, improved pharmacokinetics and effectiveness of anticancer drugs have facilitated the powerful targeting of specific agents for CC therapy. This review provides insight into current progress and future opportunities for nanomedicines as potential curative targets for CC treatment. This information could be used as a platform for the future expansion of multi-functional nano constructs for CC's advanced detection and functional drug delivery.

Abstract
UNLABELLED Endostatin, a protein derived from the cleavage of collagen XVIII by the action of proteases, is an endogenous inhibitor known for its ability to inhibit proliferation and migration of endothelial cells, angiogenesis, and tumor growth. Angiogenesis is defined as the formation of new blood vessels from pre-existing vasculature, which is crucial in many physiological processes, such as embryogenesis, tissue regeneration, and neoplasia. SUMMARY Increasing evidence shows that dysregulation of angiogenesis is crucial for the pathogenesis of renal and cardiovascular diseases. Endostatin plays a pivotal role in the regulation of angiogenesis. Recent studies have provided evidence that circulating endostatin increases significantly in patients with kidney and heart failure and may also contribute to disease progression. KEY MESSAGE In the current review, we summarize the latest findings on preclinical and clinical studies analyzing the impact of endostatin on renal and cardiovascular diseases.

Abstract
The aim of the study was to explore the optimal mechanical indexes (MIs) for low-intensity ultrasound (LIUS) combined with microbubbles to enhance tumor blood perfusion and improve drug concentration in pancreatic cancer-bearing nude mice. Fifty-four nude mice bearing bilateral pancreatic tumors on the hind legs were randomly divided into three groups (the MI was set at 0.3, 0.7 and 1.1 in groups A, B and C, respectively). Five nude mice in each group were intravenously injected with the fluorescent dye DiR iodide (DiIC18(7),1,1'-dioctadecyl-3,3,3',3'-tetramethylindotricarbocyanine iodide); for each mouse, one tumor was treated with LIUS combined with microbubbles, and the contralateral tumor was exposed to sham ultrasound. In vivo fluorescence imaging was performed to detect the enrichment of intratumoral DiR iodide. Twelve mice in each group were intravenously injected with doxorubicin (DOX) and underwent ultrasound therapy as described above. Tumor blood perfusion changes were quantitatively evaluated with pre- and post-treatment contrast-enhanced ultrasound (CEUS, MI = 0.08). One hour after the post-treatment CEUS, nude mice were sacrificed to determine the DOX concentration in tumor tissue; one mouse in each group was sacrificed after ultrasound treatment for tumor hematoxylin-eosin staining examination. CEUS quantitative analysis and in vivo fluorescence images confirmed that LIUS at MI = 0.3 combined with microbubbles was able to enhance tumor blood flow and increase regional fluorescence dye DiR iodide concentration. The DOX concentration on the therapeutic side was significantly higher than that on the control side after ultrasound-stimulated (MI = 0.3) microbubble cavitation (USMC) treatment (1.45 ± 0.53 μg/g vs. 1.07 ± 0.46 μg/g, t = -5.163, p = 0.001). However, in groups B and C, there were no significant differences in DOX concentration between the therapeutic and control sides (Z = -0.297, -0.357, p = 0.766, 0.721). No hemorrhage or other tissue damage was observed in hematoxylin-eosin-stained tumor specimens of both sides in all groups. LIUS at MI = 0.3 combined with microbubbles was able to enhance tumor blood perfusion and improve local drug concentration in nude mice bearing pancreatic cancer.

Abstract
The aim of this study was to identify the potential and mechanisms of microbubble-mediated cavitation in promoting apoptosis and suppressing invasion in cancer cells. AsPC-1 cells were used and divided into four groups: control group, microbubble-only (MB) group, ultrasound-only (US) group and ultrasound plus microbubble (US + MB) group. Pulse ultrasound was used at a frequency of 360 kHz and a SPPA (spatial peak, pulse average) intensity of 1.4 W/cm2 for 1 min (duty rate = 50%). Then cells in the four groups were cultured for 24 h. Cell Counting Kit‑8 (Biosharp, Hefei, Anhui, China) revealed decreased cell viability in the US + MB group. Western blot confirmed that there were increased cleaved caspase‑3 and Bcl-2-associated X protein levels and decreased B‑cell lymphoma‑2 (Bcl-2) levels, as well as increased intracellular calcium ions and downregulated cleaved caspase-8, in the US + MB group. With respect to proliferation, cells in the US + MB group had lower expression of Ki67 and the weakened colony formation ability. The transwell invasion assay revealed that invasion ability could be decreased in AsPC-1 cells in the US + MB group. Further, it was found that cells in the US + MB group had lower levels of hypoxia-inducible factor-1α (HIF-1α) and vimentin and higher levels of E-cadherin compared with the other three groups. Finally, the US + MB cells had less invadopodium formation. In conclusion, these results suggest that microbubble-mediated cavitation promotes apoptosis and suppresses invasion in AsPC-1 cells.

Tumor perfusion enhancement by ultrasound stimulated microbubbles potentiates PD-L1 blockade of MC38 colon cancer in mice. Cancer Lett 2020; 498:121-129.

Abstract
Cancer immunotherapy holds tremendous promise as a strategy for eradicating solid tumors, and its therapeutic effect highly relies on sufficient CD8+ T cells infiltration. Here, we demonstrate that ultrasound stimulated microbubble cavitation (USMC) promotes tumor perfusion, thereby increasing CD8+ T cells infiltration and anti-PD-L1 antibody delivery, then further enhancing the PD-L1 blockade of MC38 colon cancer in mice. Firstly, we optimized the mechanic index (MI) of ultrasound, and found that USMC with MI of 0.4 (equal to peak negative pressure of 0.8 MPa) significantly improved the peak intensity and area under curve of tumor contrast-enhanced ultrasound. Also, flow cytometry exhibited higher percentage of infiltrating CD8+ T cells in the USMC (MI = 0.4)-treated tumors than that of the control. We further explored the combination therapy of optimized USMC with anti-PD-L1 antibody. The combination therapy enhanced tumor perfusion and even led to the tumor vascular normalization. More importantly, flow cytometry showed that the combination not only increased the percentage and absolute number of tumor infiltrating CD8+ T cells, but also promoted the expression of Ki67 as well as the secretions of IFN γ and granzyme B, therefore, the combination therapy achieved greater tumor growth inhibition and longer survival than that of the monotherapies. These suggest that USMC is a promising therapeutic modality for combining immune checkpoint blockade against solid tumors.

Abstract
Ultrasound combined with microbubbles (USMB) is a promising antitumor therapy because of its capability to selectively disrupt tumor perfusion. However, the antitumor effects of repeated USMB treatments have yet to be clarified. In this study, we established a VX2 muscular tumor xenograft model in rabbits, and performed USMB treatments at five different peak negative acoustic pressure levels (1.0, 2.0, 3.0, 4.0, or 5.0 MPa) to determine the appropriate acoustic pressure. To investigate whether repeated USMB treatments could improve the antitumor effects, a group of tumor-bearing rabbits was subjected to one USMB treatment per day for three consecutive days for comparison with the single-treatment group. Contrast-enhanced ultrasonic imaging and histological analyses showed that at an acoustic pressure of 4.0 MPa, USMB treatment contributed to substantial cessation of tumor perfusion, resulting in severe damage to the tumor cells and microvessels without causing significant effects on the normal tissue. Further, the percentages of damaged area and apoptotic cells in the tumor were significantly higher, and the tumor growth inhibition effect was more obvious in the multiple-treatment group than in the single USMB treatment group. These findings indicate that with an appropriate acoustic pressure, the USMB treatment can selectively destroy tumor vessels in muscular tumor xenograft models. Moreover, the repeated treatments strategy can significantly improve the antitumor effect. Therefore, our results provide a foundation for the clinical application of USMB to treat solid tumors using a novel therapeutic strategy.

Abstract
Ultrasound cavitation therapy has attracted much attention in recent years because the cavitation of microbubbles can be leveraged to boost the infiltration of chemotherapeutic drugs into cancer tissues. For breast cancer therapy, most of the previously reported microbubbles lack specific targeting capacity and permeability. In this study, we have successfully fabricated Y1 receptor ligand (NPY)-modified bubbles, and examined their therapeutic efficacies as size-dependent functions with or without NPY targeting. To achieve this, four types of micro-scale bubbles (MBs or MBs-NPY) and nano-scale bubbles (NBs or NBs-NPY) were comprehensively evaluated. In vivo results indicated that the NBs-NPY group with doxorubicin (DOX) under ultrasound irradiation showed a high tumor suppression effect and a prolonged survival time. Furthermore, the NBs-NPY with DOX group exhibited minimal damage to mouse vital organs, which points to the considerable tolerance of the proposed nanosystem for efficacious breast cancer therapy. In summary, these findings suggest that the developed NPY-targeted NBs could have a broad application prospect in ultrasound cavitation chemotherapy of Y1 receptor-overexpressed breast cancer.

ULTRASOUND IN MEDICINE & BIOLOGY 2020; 46:679-689.

Abstract
The aim of the study described here was to investigate whether ultrasound-mediated microbubble destruction (UTMD) of targeted microbubbles conjugated with an anti-vascular endothelial growth factor receptor 2 (anti-VEGFR2) antibody can enhance the therapeutic effect of doxorubicin (DOX) on a mouse hepatocellular carcinoma (HCC) model bearing HEP-G2-RFP tumors. The growth of liver tumors in mice was inhibited by using Visistar VEGFR2 plus ultrasound irradiation and by DOX alone. DOX plus UTMD had an inhibitory effect on tumor growth beginning on the seventh day of treatment, while Visistar VEGFR2 alone and DOX alone had inhibitory effects beginning on the 11th day. DOX + UTMD significantly decreased tumor volume and tumor weight compared with DOX alone (p < 0.05) and Visistar VEGFR2 alone (p < 0.05). Compared with DOX alone and Visistar VEGFR2 alone, DOX + UTMD had the highest inhibitory effect on tumor angiogenesis and the highest apoptosis index. UTMD-targeted microbubbles can significantly enhance the antitumor effect of DOX on a mouse HCC model, inhibit angiogenesis and induce apoptosis in tumor cells.

Abstract
Ultrasound-mediated targeted delivery (UMTD), a novel delivery modality of therapeutic materials based on ultrasound, shows great potential in biomedical applications. By coupling ultrasound contrast agents with therapeutic materials, UMTD combines the advantages of ultrasound imaging and carrier, which benefit deep tissue penetration and high concentration aggregation. In this paper we introduced recent advances in ultrasound contrast agents and applications in tumor therapy. Ultrasound contrast agents were categorized by their functions, mainly including thermosensitive, pH-sensitive and photosensitive ultrasound contrast agents. The various applications of UMTD in tumor treatment were summarized as follows: drug therapy, transfection of anti-oncogene, RNA interference, vaccine immunotherapy, monoclonal antibody immunotherapy, adoptive cellular immunotherapy, cytokine immunotherapy, and so on. In the end, we elaborated on the current challenges and provided perspectives of UMTD for clinical applications.

Abstract
Drug delivery for tumor theranostics involves the extensive use of the enhanced permeability and retention (EPR) effect. Previously, various types of nanomedicines have been demonstrated to accumulate in solid tumors via the EPR effect. However, EPR is a highly variable phenomenon because of tumor heterogeneity, resulting in low drug delivery efficacy in clinical trials. Because ultrasonication using micro/nanobubbles as contrast agents can disrupt blood vessels and enhance the specific delivery of drugs, it is an effective approach to improve the EPR effect for the passive targeting of tumors. In this review, the basic thermal effect, acoustic streaming, and cavitation mechanisms of ultrasound, which are characteristics that can be utilized to enhance the EPR effect, are briefly introduced. Second, micro/nanobubble-enhanced ultrasound imaging is discussed to understand the validity and variability of the EPR effect. Third, because the tumor microenvironment is complicated owing to elevated interstitial fluid pressure and the deregulated extracellular matrix components, which may be unfavorable for the EPR effect, few new trends in smart bubble drug delivery systems, which may improve the accuracy of EPR-mediated passive drug targeting, are summarized. Finally, the challenging and major concerns that should be considered in the next generation of micro/nanobubble-contrast-enhanced ultrasound theranostics for EPR-mediated passive drug targeting are also discussed.

Abstract
Studies investigating mild Traumatic Brain Injury (mTBI) in the military population using experimental head surrogates and Finite Element (FE) head models have demonstrated the existence of transient negative pressures occurring within the head at the contrecoup location to the blast wave impingement. It has been hypothesized that this negative pressure may cause cavitation of cerebrospinal fluid (CSF) and possibly lead to brain tissue damage from cavitation bubble collapse. The cavitation pressure threshold of human CSF is presently unknown, although existing FE studies in the literature have assumed a value of -100 kPa. In the present study, the cavitation threshold of degassed porcine CSF at body temperature (37 °C) was measured using a unique modified Polymeric Split Hopkinson Pressure Bar apparatus, and compared to thresholds of distilled water at various conditions. The loading pulse generated in the apparatus was comparable to experimentally measured pressures resulting from blast exposure, and those predicted by an FE model. The occurrence of cavitation was identified using high-speed imaging and the corresponding pressures were determined using a computational model of the apparatus that was previously developed and validated. The probability of cavitation was calculated (ISO/TS, 18506) from forty-one experimental tests on porcine CSF, representing an upper bound for in vivo CSF. The 50% probability of cavitation for CSF (-0.467 MPa ± 7%) was lower than that of distilled water (-1.37 MPa ± 16%) under the same conditions. The lesser threshold of CSF could be related to the constituents such as blood cells and proteins. The results of this study can be used to inform FE head models subjected to blast exposure and improve prediction of the potential for CSF cavitation and response of brain tissue.

Abstract
Residual cancer after incomplete ablation remains a major problem for radiofrequency ablation (RFA). We aimed to investigate the synergetic treatment efficacy of RFA combined with ultrasonic cavitation for liver tumor. Sixty rabbits with VX2 liver tumor were randomly divided into three groups. Group A was control group without any treatment. Combined ultrasonic cavitation with RFA was performed for group B1. Group B2 underwent RFA alone. The histopathological results were compared at the 5th, 11th, and 18th day of experiment, and the survival time and metastasis were assessed. The tumor volume growth rate, percentage of necrosis area, microvessel density, and apoptosis index showed significant differences among these groups at the 5th day, 11th day, and 18th day of experiment (P < .05). In contrast, the difference of metastatic score was not significant at the 5th and 11th day (P > .05). At the 18th day, the metastatic score of group A was significant higher than that of group B1 (P < .05), whereas the differences between group A and group B2, or group B1 and group B2 were not significant (P > .05). The median/range interquartile of survival time in groups A, B1, and B2 were 25/8 days, 50/19 days, and 48/20 days, respectively, and there was significant difference between groups A and B1 or B2 (P < .05). The difference between groups B1 and B2 was not significant (P > .05). Ultrasonic cavitation after incomplete RFA for liver tumor improved the antitumor effect, which could be considered as a potentially useful combined therapeutic strategy for liver malignancy.

Abstract
AIM Though Endostar (ES) could inhibit tumor growth by inhibiting tumor angiogenesis, other possible mechanisms have been less reported. This study aims to investigate the role of ES in the treatment of lung cancer from the perspective of macrophage-mediated epithelial mesenchymal transformation (EMT). METHODS THP1 cells were induced to polarized macrophages (MΦ). A549 and H1795 cells were separately treated with MΦ conditioned medium, ES (12.5 μg/ml) and HGF (5 ng/ml) for 24 h at 37 °C. Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to detect the expression levels of CCL17, CD163, hepatocyte growth factor (HGF), Epidermal Growth Factor (EGF), transforming growth factor (TGF)-β1 and interleukin (IL)-6. Western blot was carried out to detect the p-MET, MET and EMT-related proteins (E-cadherin, N-cadherin, Snail and vimentin). Fibroblast-like A549 and H1975 cells were observed by a microscope. Cell invasion and migration were observed and analyzed by transwell and scratch assays. RESULTS The expression levels of CCL17 and CD163 were significant higher in MΦ. ES significantly inhibited the expression of HGF in MΦ. Moreover, ES could restore the abnormal expressions of EMT-related proteins and inhibit MΦ-induced and HGF-induced fibroblast-like lung cancer cells. Furthermore, ES suppressed the MΦ-induced and HGF-induced migration and invasion of lung cancer cells. ES was also found to down-regulate HGF-Met signaling in HGF-treated lung cancer cells. CONCLUSION ES suppresses lung cancer progression by down-regulating HGF-Met signaling, revealing the possible mechanism of ES in the process of treating lung cancer patients.

Abstract
Background:
Ultrasound has been widely used in clinical diagnosis because it is noninvasive,
inexpensive, simple, and reproducible. With the development of molecular imaging, material
science, and ultrasound contrast agents, ultrasound-targeted delivery technology has emerged. The interaction
of ultrasound and molecular probes can be exploited to change the structures of cells and tissues
in order to promote the targeted release of therapeutic substances to local tumors. The targeted
delivery of drugs, genes, and gases would not only improve the efficacy of tumor treatment but also
avoid the systemic toxicity and side effects caused by antitumor treatments. This technology was recently
applied in clinical trials and showed enormous potential for clinical application.
Objective:
This article briefly introduces the characteristics of the tumor microenvironment and the
principle of ultrasound-targeted delivery technology. To present recent progress in this field, this review
focuses on the application of ultrasound-targeted delivery technology in tumor-targeted therapy,
including drug delivery, gene transfection, and gas treatment.
Results:
The results of this study show that ultrasound-targeted delivery technology is a promising
therapeutic strategy for tumor treatment.
Conclusion:
Ultrasound-targeted delivery technology shows promise with regard to cancer treatment.

Ultrasound Microbubble Delivery Targeting Intraplaque Neovascularization Inhibits Atherosclerotic Plaque in an APOE-deficient Mouse Model. In Vivo 2018; 32:1025-1032.

Abstract
BACKGROUND/AIM Intraplaque neovascularization is often associated with plaque formation, development and instability, and clinical symptoms in atherosclerosis. The aim of the present study was to investigate a new strategy for treating athrosclerosis by ultrasound-targeted microbubble delivery (UTMD) targeting intraplaque neovascularization in an APOE-deficient mouse model of atherosclerosis. MATERIALS AND METHODS A mouse model of atherosclerosis was induced by feeding Apoe-/- mice a hypercholesterolemic diet and was verified with hematoxylin and eosin staining and intercellular adhesion molecule 1 (ICAM-1) expression. Targeted microbubbles (MB) were prepared by conjugating microbubbles with biotinylated antibody to ICAM1 (MBi) or with both biotinylated anti-ICAM1 and the angiogenesis inhibitor Endostar (MBie). The targeted microbubbles were analyzed with epifluorescence microscopy and flow cytometry. The animals with induced atherosclerotic plaques received MBi or MBie followed by UTMD treatment. Endostar treatment alone was given to other animals for comparison. Morphological assessment of atherosclerotic plaques was performed after treatment. The expression of angiogenesis marker CD31 was detected by immunohistochemical analysis. RESULTS Atherosclerotic plaques developed in the entire aorta with significant intraplaque ICAM-1 expression in the APOE-deficient mice following a 30-week hypercholesterolemic diet. Microbubbles were successfully conjugated with anti-ICAM-1 and Endostar, with a conjugation rate of 98.3% and 63.5%, respectively. UTMD with MBie significantly reduced the area of atherosclerotic plaque as compared to the model control (p<0.05). Treatment with Endostar and UTMD with MBie significantly reduced CD31 expression compared with the model control group (p<0.01). Greater significant inhibitory effect on CD31 expression was found in the group treated with UTMD and MBie compared to the Endostar- and UTMD with MBi groups (p<0.01). CONCLUSION UTMD targeting intraplaque neovascularization was found to inhibit atherosclerotic plaque in a mouse model of atherosclerosis, suggesting the potential of microbubble-mediated ultrasound technology in aiding drug delivery for atherosclerosis treatment.

Abstract
The Notch signaling pathway has been identified as a therapeutic target for cancers. γ-Secretase inhibitors (GSIs) have been progressively recognized as potential anticancer drugs. The present study aimed to investigate the effects of anti-delta like legend 4 (anti-DLL4) treatment on the anticancer efficacy of GSIs in gastric cancer. SGC-7901-GFP human gastric cancer cells were tested for DLL4 expression by rosette formation test and immunofluorescence, and then were treated with anti-DLL4 antibody N-[N-(3,5-difluorophenacetyl)-L-ananyl]-S-phenylglycine t-butyl ester (DAPT, a type of GSI), or a combination of anti-DLL4 antibody and DAPT. The effects of in vitro treatments on cell apoptosis, cell cycle, and cell invasion were analyzed. For in vivo study, an orthotopic mouse model of gastric cancer was established with green fluorescence expressing SGC-7901. Ultrasound targeted microbubble destruction was used to treat tumor-bearing mice with anti-DLL4 antibody conjugated microbubbles, DAPT, and a combination of the two. Real-time fluorescence imaging was performed to assess tumor cell inhibition in each group. Following in vivo treatments, apoptosis of tumor cells and the expression of apoptosis-related genes BAX, Bcl-2, and P53 were detected by TUNEL and immunohistochemical staining. In vivo combined treatment of anti-DLL4 and DAPT led to a higher rate of cell apoptosis and greater inhibition of cell invasion than that observed with DAPT treatment alone. DAPT and anti-DLL4 combination therapy resulted in decreased cell distribution at G1 phase and increased cell distribution at S phase, compared to the untreated control group (P < .01). In vivo combined therapy with anti-DLL4 and DAPT significantly increased tumor growth inhibition and tumor cell apoptosis when compared to DAPT therapy alone (P < .05). In addition, combined treatment significantly increased expression of BAX and P53 and reduced Bcl-2 expression (P < .05). Conversely, treatment with DAPT alone only increased expression of BAX and P53 (P < .05), suggesting that the reduction of Bcl-2 expression may play an important role in the synergetic antitumor and proapoptosis effects of the combined treatment. Concurrent treatment with anti-DLL4 enhances the antitumor and proapoptotic efficacy of the γ-secretase inhibitor in gastric cancer both in vitro and in vivo.

Insufficient radiofrequency ablation promotes proliferation of residual hepatocellular carcinoma via autophagy. Cancer Lett 2018; 421:73-81. [PMID: 29458142 DOI: 10.1016/j.canlet.2018.02.024] [Citation(s) in RCA: 44] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2017] [Revised: 02/11/2018] [Accepted: 02/12/2018] [Indexed: 01/07/2023]
Abstract
Radiofrequency ablation (RFA) is considered to be a potentially curative therapy for hepatocellular carcinoma (HCC). However, insufficient RFA (IRFA) can promote rapid progression of the residual tumor. The mechanisms underlying IRFA-induced tumor promotion remain poorly understood. In the present study, we have established a subcutaneous xenograft mouse model and monitored the location and extent of IRFA by dual monitoring with ultrasonography and a thermal imager. For the first time, we provide evidence of the activation of autophagic pathways in mice exposed to IRFA. We show that autophagy plays an important role in relapse and proliferation after IRFA and that hydroxychloroquine (HCQ) can suppress these effects. Our findings indicate that autophagy is involved in experimental IRFA and that inhibition of autophagy may be a novel approach in the treatment of local recurrences of HCC after IRFA in the clinic.

Abstract
BACKGROUND The purpose of the study was to investigate the ability of microbubbles (MBs) targeting interleukin-18 (IL-18) to detect plaques in a rabbit atherosclerotic plaque model. MATERIAL AND METHODS A rabbit atherosclerotic plaque model was established. The locations of the atherosclerotic plaques were verified by two-dimensional scanning and color Doppler flow imaging. An IL-18 antibody was conjugated to naked MBs (MBc) using the biotin-streptavidin conjugation method, resulting in the formation of MBIL-18. MBc and MBIL-18 were then used for contrast-enhanced ultrasound (CEUS) studies. The locations of CD34 and IL-18 within the plaques were determined by immunohistochemistry, and IL-18 expression levels in the plaques were determined by Western blot analysis. The relationships between IL-18 expression and the contrast intensity of the 2 MBs were analyzed. RESULTS MBc and MBIL-18 were both uniformly dispersed. Fluorescence microscopy and flow cytometry revealed that IL-18 was successfully conjugated to MBs. CEUS images showed that the intensity of the MBIL-18 signal was substantially enhanced and prolonged compared with that of the MBc signal. Immunohistochemistry showed that CD34 expression was significantly increased in the plaques and that IL-18 was mainly located in the inner parts and base of the atherosclerotic plaques. Western blot analysis revealed that IL-18 expression was higher in the plaque regions. Correlation analysis showed that IL-18 expression was correlated with the contrast intensity of MBIL-18 (r=0.903, P<0.05) but not with MBc (r=0.540, P>0.05). CONCLUSIONS MBs targeting IL-18 may be a novel, noninvasive method of diagnosing atherosclerotic plaques.

Abstract
BACKGROUND Due to different physical and biological mechanisms behind ultrasound hyperthermia and phonophoresis, the requirement for ultrasound power, frequency and control modes varies. OBJECTIVE This paper introduces an adaptive ultrasonic physiotherapy system based on real-time surveillance over physiological characteristics of the patients, which in turn assists the individual treatment and dose limitation in auxiliary rehabilitation. METHODS The method essentially takes advantage of distinctive characteristics of two different phases (systole and diastole) of the human cardiac cycle as a medium for modulation. The abundance of blood flow during systole enables energy exchange for hyperthermia while blood flow insufficiency caused by diastole assists in drug penetration. Said method could improve the adjuvant therapy as it provides partial drug penetration and therapeutic dosage control. RESULTS By adjusting time window and intensity of multi-frequency ultrasound, it is possible to reduce the irradiation dosage to around 22% of that during continuous irradiation at 1 MHz. The method shows high potential in clinical practice. CONCLUSION Frequency-tuning ultrasound therapy would be more efficient regarding drug penetration and improve the therapeutic efficacy of hyperthermia.

Short Hairpin RNA Knockdown of Connective Tissue Growth Factor by Ultrasound-Targeted Microbubble Destruction Improves Renal Fibrosis. ULTRASOUND IN MEDICINE & BIOLOGY 2016; 42:2926-2937.

Abstract
The purpose of this study was to evaluate whether ultrasound-targeted microbubble destruction transfer of interfering RNA against connective tissue growth factor (CTGF) in the kidney would ameliorate renal fibrosis in vivo. A short hairpin RNA (shRNA) targeting CTGF was cloned into a tool plasmid and loaded onto the surface of a cationic microbubble product. A unilateral ureteral obstruction (UUO) model in mice was used to evaluate the effect of CTGF knockdown. Mice were administered the plasmid-carrying microbubble intravenously, and ultrasound was applied locally to the obstructed kidney. Mice undergoing a sham UUO surgery and untreated UUO mice were used as disease controls, and mice administered plasmid alone, plasmid with ultrasound treatment and microbubbles and plasmid without ultrasound were used as treatment controls. Mice were treated once and then evaluated at day 14. CTGF in the kidney was measured by quantitative reverse transcription polymerase chain reaction and Western blot. Expression of CTGF, transforming growth factor β1, α smooth muscle actin and type I collagen in the obstructed kidney was evaluated by immunohistochemistry. The cohort treated with plasmid-carrying microbubbles and ultrasound exhibited reduced mRNA and protein expression of CTGF (p < 0.01). Furthermore, CTGF gene silencing decreased the interstitial deposition of transforming growth factor β1, α smooth muscle actin and type I collagen as assessed in immunohistochemistry, as well as reduced renal fibrosis in pathologic alterations (p < 0.01). No significant changes in target mRNA, protein expression or disease pathology were observed in the control cohorts. A single treatment of ultrasound-targeted microbubble destruction is able to deliver sufficient shRNA to inhibit the expression of CTGF and provide a meaningful reduction in disease severity. This technique may be a potential therapy for treatment of renal fibrosis.

Abstract
Ultrasonic cavitation is a novel potential approach for cancer treatment. We optimized the techniques of ultrasonic cavitation to enhance antitumor efficacy in a mouse model with human pancreatic cancer. A polydisperse MB contrast agent formulation (TS-P) with a mean number diameter of 1.9 μm was depleted in small diameter particles by differential centrifugation, producing an “up-sized” size distribution (TS-PL) possessing a mean diameter of 2.9 μm. Mice bearing the XPA-1-RFP pancreatic tumor were treated daily for 3 consecutive days with either up-sized or standard MB. Both treatment cohorts exhibited a significant reduction in tumor volume relative to the untreated control cohort (P < 0.05), and TS-PL group has significantly reduction in tumor volume (1215.1± 324.7 mm3) compared with standard TS-P group (2131.2±753.4 mm3) (P < 0.05). The treatment with TS-PL resulted in more tumor cell necrosis and apoptosis than with TS-P. Decreased expression of CD31 and MVD was observed histologically in tumors treated with TS-PL relative to TS-P. This study demonstrates that tuning the size distribution of existing contrast agent products, specifically to reduce the concentration of small MB, is required for enhanced anti-tumor cavitation activity.

Abstract
INTRODUCTION Drug delivery pertaining to acoustic cavitation generated from ultrasonic (US) irradiation is advantageous for devising smarter and more advanced therapeutics. The aim is to showcase microbubbles as drug carriers and robust theranostic for non-invasive therapies across diverse biomedical disciplines, highlighting recent technologies in this field for overcoming the blood-brain barrier (BBB) to treat cancers and neurological disorders. AREAS COVERED This article reviews work on the optimized tuning of ultrasonic parameters, sonoporation, transdermal and responsive drug delivery, acoustic cavitation in vasculature and oncology, contrast imaging for real-time magnification of cell-microbubble dynamics and biomolecular targeting. Scholarly literature was sought through database search on key terminology, latest topics, reputable experts and established journals over the last five years. EXPERT OPINION Cavitation offers immense promise in overcoming current diffusion and convection limitations for treating skull/brain/vascular/tissue injuries and ablating tumors to minimize chronic/acute effects. Since stable cavitation facilitates the restoration of US-opened BBB and the modulation of drug concentration, US equipment with programmable imaging modality and sensitivity are envisaged to create safer miniaturized devices for personalized care. Due to differing biomedical protocols with regard to specific medical conditions, quantitative and qualitative controls are mandatory before translation to real-life clinical applications can be accomplished.

Abstract
OBJECTIVES The poor safety profile of sunitinib capsules has encouraged the identification of targeted drug delivery systems against renal cell carcinoma. This study aimed to explore the effect of sunitinib-loaded microbubbles along with ultrasound (US) treatment on proliferation and apoptosis of human GRC-1 granulocyte renal carcinoma cells in vitro and in vivo (xenograft tumor growth in nude mice). METHODS Liposomes containing sunitinib were prepared by using the transmembrane ammonium sulfate gradient method and then absorbed into polymer microbubbles to generate sunitinib-loaded microbubbles. Entrapment of sunitinib was verified by 25-25-[N-[(7-nitro-2-1,3-benzoxadiazol-4-yl)methyl]amino]-27-norcholesterol staining. GRC-1 cells were treated with microbubbles alone, liposomes alone, sunitinib alone, sunitinib-loaded microbubbles without and with US, and no treatment (control). Cell survival and apoptosis were assessed at 12, 24, and 48 hours after treatment. Xenograft tumors were induced by implantation of GRC-1 cells in nude mice. The animals with tumors were then randomly assigned to sunitinib alone, sunitinib-loaded microbubbles - US, sunitinib-loaded microbubbles + US, and no treatment (control; n = 10 per group). The tumor volumes were analyzed on the 7th, 15th, and 21st days. RESULTS The sunitinib entrapment efficiency in the liposomes was approximately 78%. The effective sunitinib concentration in each group was 0.1 μg/mL. The sunitinib-loaded microbubble + US group showed a lower in vitro cell survival rate (P < .001) compared with the other groups. Greater in vivo inhibition of xenograft tumor growth was also observed in the sunitinib-loaded microbubble + US group compared with the other groups. CONCLUSIONS Combined sunitinib-loaded microbubbles and US treatment significantly inhibits growth of renal carcinoma cells both in vitro and in vivo.

Abstract
The literature describing the use of low-intensity ultrasound in four major areas of cancer therapy-sonodynamic therapy, ultrasound-mediated chemotherapy, ultrasound-mediated gene delivery and anti-vascular ultrasound therapy-was reviewed. Each technique consistently resulted in the death of cancer cells, and the bio-effects of ultrasound were attributed primarily to thermal actions and inertial cavitation. In each therapeutic modality, theranostic contrast agents composed of microbubbles played a role in both therapy and vascular imaging. The development of these agents is important as it establishes a therapeutic-diagnostic platform that can monitor the success of anti-cancer therapy. Little attention, however, has been given either to the direct assessment of the mechanisms underlying the observed bio-effects or to the viability of these therapies in naturally occurring cancers in larger mammals; if such investigations provided encouraging data, there could be prompt application of a therapy technique in the treatment of cancer patients.
