Cryptochrome 2 is involved in betacyanin decomposition induced by blue light in Suaeda salsa

Functional Plant Biology (2006)

Changquan Wang Tao Liu

Seeds of the halophyte Suaeda salsa (L.) Pall. were cultured in 24 h dark and 14 h blue light / 10 h dark to examine the role of blue light and the blue-light-absorbing photoreceptor cryptochrome 2 (CRY2) in betacyanin accumulation, hypocotyl elongation and cotyledon opening in S. salsa seedlings. Darkness significantly promoted betacyanin accumulation and hypocotyl elongation but inhibited cotyledon opening. Blue light suppressed betacyanin accumulation and hypocotyl elongation but stimulated cotyledon opening. Betacyanin in S. salsa seedlings decomposed with time in blue light. Western blot analysis showed that CRY2 protein accumulated both in hypocotyls and cotyledons of S. salsa seedlings grown in dark, but degraded with time in blue light, which was paralleled by a decrease of tyrosine hydroxylation activity of tyrosinase, a key enzyme involved in the betalain biosynthesis pathway. These results suggest that CRY2 protein mediates betacyanin decomposition via inactivation of tyrosinase in S. salsa seedlings, and the blue-light-dependent degradation of CRY2 protein is crucial to its function.

Evaluation of the Hair Cell Regeneration in Zebrafish Larvae by Measuring and Quantifying the Startle Responses

Neural Plasticity (2017)

Changquan Wang Zhenmin Zhong Peng Sun Hanbing Zhong Hongzhe Li

The zebrafish has become an established model organism for the study of hearing and balance systems in the past two decades. The classical approach to examine hair cells is to use dye to conduct selective staining, which shows the number and morphology of hair cells but does not reveal their function. Startle response is a behavior closely related to the auditory function of hair cells; therefore it can be used to measure the function of hair cells. In this study, we developed a device to measure the startle response of zebrafish larvae. By applying various levels of stimulus, it showed that the system can discern a 10 dB difference. The hair cell in zebrafish can regenerate after damage due to noise exposure or drug treatment. With this device, we measured the startle response of zebrafish larvae during and after drug treatment. The results show a similar trend to the classical hair cell staining method. The startle response was reduced with drug treatment and recovered after removal of the drug. Together it demonstrated the capability of this behavioral assay in evaluating the hair cell functions of fish larvae and its potential as a high-throughput screening tool for auditory-related gene and drug discovery.

Soft-switching analysis of a resonant capacitor current feedback self-oscillating inverter

Mingsong Shao Songling Huang Wei Zhao Changquan Wang

In this paper, we examine a resonant capacitor current feedback (RCCF) self-oscillating resonant inverter from nonlinear point of view. By adopting a four-stage equivalent model, we derive the soft-switching dead time from time-domain for the series resonant capacitor linked parallel load circuit. Importantly, we propose a nonlinear model for the current feedback and gate-drive circuit. Based on analyzing the switching transition interval of this model, the determination of feedback parameters is inferred with given input power and resonant elements. Experimental results have been obtained for a RCCF self-oscillating inverter operating at 3 MHz and 300 V bus voltage.

Adipose tissue-derived stem cells embedded with eNOS restore cardiac function in acute myocardial infarction model

Heart (2011)

Shichunzhi Z. H. Li Xujianzhong Zhaofang Yin Y. Yuqin

Objective

This study assessed the potential therapeutic efficacy of endothelial NO syntheses (eNOS)-expressing adipose tissue-derived stem cells (ADSCs) on infarcted hearts.

Methods

We isolated CD29+, CD44+, CD45 cells from adipose tissue. We hypothesised that combination of eNOS over-expression and transplantation of ADSCs could restore NO bioavailability and improve cardiac function in infarcted hearts.

Results

Here with several lines of experimental evidences, we demonstrated that ADSCs with eNOS-overexpression induced eNOS expression in host endothelial cells and vascular smooth muscle cells, both in vitro and in vivo. This effect was possibly mediated by calcium signal. Transplantation of ADSCs with eNOS embedded showed great therapeutic efficacy in reduction of infarcted size, compared with normal ADSC.

Conclusions

Results of this study suggest that ADSCs could be an attractive vehicle for the exogenous eNOS expression into heart after infarction, which is beneficial to restoration of cardiac function. Paracrine effect by mobilising the host endothelial cells and smooth muscle cells may be the mechanism underlying the therapeutic effect.
