Ultrasound-responsive theranostic platform for real-time monitoring and efficient thrombolysis in tPA-resistant thrombi

Project description:There is no noninvasive solution for tPA-resistant thrombi while endovascular thrombectomy is the last option. Here, we proposed neutrophil extracellular traps (NETs), ε-(γ-glutamyl)lysine isopeptide bonds and fibrin scaffold as keychain in tPA-resistant thrombus, which was confirmed in the thrombi retrieved from stroke patients. A theranostic platform was designed for the combination of sonodynamic and mechanical thrombolysis under the guidance of ultrasonic imaging. Three rounds of 10 min noninvasive treatment led to the breakdown of the keychain, achieving great recanalization rate of 90% in rat occlusion model while tPA only made 10% improvement. RNA sequencing results and endothelium functional tests jointly indicated that the vascular homeostasis can be effectively reconstructed. The noninvasive theranostic capability presented in pig’s lengthy thrombi (>8mm) and thrombosis-susceptible tissue engineered vascular grafts (TEVGs) indicated its clinical transformation prospects. Taken together, this non-invasive theranostic platform provides a new strategy for tPA-resistant thrombi.

Identification of genes responsive to ultrasound in human leukemia U937 cells

Project description:Here, the effects of non-thermal low intensity pulsed ultrasound (LIPUS) on the gene expression in human lymphoma U937 cells were investigated using by an Affymetrix GeneChip system. Six hours after LIPUS treatment (0.3 W/cm2 for 1 min), apoptosis (14±3.8%, mean±SD) with minimal cell lysis was observed. At 3 h post-treatment, LIPUS down-regulated 193 genes and up-regulated 201 genes by >1.5-fold. Keywords: ultrasound, gene expression, Human lymphoma U937 cell

Genetic analysis, ultrasound phenotype, and pregnancy outcome of fetuses with Xp22.33 or Yp11.32 microdeletion

Project description:The phenotypes of Xp22.33 or Yp11.32 microdeletions containing short-stature homeobox (SHOX) gene have been extensively described in adults and children, however, few have been reported in prenatal fetuses. We analyzed the prenatal ultrasound phenotype and pregnancy outcomes of fetuses with Xp22.33 or Yp11.32 microdeletion containing SHOX gene to improve the understanding, diagnosis, and monitoring of the disease in the fetal period.

Transcription profiling of human leukemia U937 cells treated with the combination of Sonazoid and ultrasound

Project description:Echo-contrast agents enhance the echogenicity of ultrasound and have been clinically used for diagonosis in current medical fields. Here, the combined effects of Sonazoid, an echo-contrast agent, and ultrasound on the gene expression in human lymphoma U937 cells were investigated using an Affymetrix GeneChip system. The cells were treated with Sonazoid (0.05%; Sonazoid only), ultrasound (0.3 W/cm2 for 1 min; ultrasound only) and the combination of Sonazoid and ultrasound (0.05% Sonazoid plus ultrasound 0.3 W/cm2 for 1 min; Sonazoid + Ultrasound) and followed by incubation for 3 h at 37Â°C. The percentage of DNA fragmentation 6 h after treatment was 5.8 Â± 1.0 (mean Â± SD, n = 3), 6.0 Â± 0.4, 13.5 Â± 1.0, and 18.3 Â± 2.3 in cells treated with control, Sonazoid only, ultrasound only and Sonazoid + Ultrasound, respectively. Of approximately 47,000 probe sets analyzed, probe sets that were differentially expressed by a factor 2.0 or greater were 40, 184 and 144 in cells treated with Sonazoid only, ultrasound only and Sonazoid + Ultrasound, respectively. Experiment Overall Design: U937 cells, a human lymphoma cell line, were treated with Sonazoid (0.05%), ultrasound (0.3 W/cm2 for 1 min) and the combination of Sonazoid and ultrasound (0.05% Sonazoid plus ultrasound 0.3 W/cm2 for 1 min) and followed by incubation for 3 h at 37Â°C. Non-treated cells were served as control. Total RNA samples were prepared from the cells. Gene expression was analyzed by an Affymetrix GeneChipÂ® system with a Human Genome U133-plus 2.0 array for analysis of over 47,000 transcripts. Sample preparation for array hybridization was carried out as described in the manufacturerâ??s instructions.

Induction of a torpor-like hypothermic and hypometabolic state in rodents by ultrasound

Project description:Torpor is an energy-conserving state in which animals dramatically decrease their metabolic rate and body temperature to survive harsh environmental conditions. Here, we report the noninvasive, precise, and safe induction of a torpor-like hypothermic and hypometabolic state in rodents by remote transcranial ultrasound stimulation at the hypothalamus preoptic area (POA). We achieve a long-lasting (> 24 hours) torpor-like state in mice via closed-loop feedback control of ultrasound stimulation with automated detection of body temperature. Ultrasound-induced hypothermia and hypometabolism (UIH) is triggered by activation of POA neurons, involves the dorsomedial hypothalamus as a downstream brain region and subsequent inhibition of thermogenic brown adipose tissue. Single-nucleus RNA-sequencing of POA neurons reveals TRPM2 as an ultrasound-sensitive ion channel, the knockdown of which suppresses UIH. We also demonstrate that UIH is feasible in a non-torpid animal, the rat. Our findings establish UIH as a promising technology for the noninvasive and safe induction of a torpor-like state. To investigate the mechanism of ultrasound-induced neuronal activation, we applied ultrasound stimulation in hypothalamic preoptic area region and performed single-nuclei RNA sequencing in the ultrasound stimulated neurons (US+) and neurons without ultrasound stimulation (US-). In our sn-RNAseq analysis, we examined the association between the expression of neuronal activation markers (or IEGs) and ion channels, as well as neuron types.
