An ultra effective method of generating extra multipotent cells from human fibroblasts via ultrasound-directed instant chromatin remodeling [MBD-seq]

ABSTRACT: We have developed an ultra effective method of generating extra multipotent (xpotent) cells which have differentiation potential more than limited cell types, by the mechanism of ultrasound-directed permeation of environmental transition-guided cellular reprogramming (Entr).

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.
