| 2 | miR-21 promotes the differentiation of hair folliclederived neural crest stem cells into Schwann cells显示文摘Hair follicle-derived neural crest stem cells can be induced to differentiate into Schwann cells in vivo and in vitro. However, the underlying regulatory mechanism during cell differentiation remains poorly understood. This study isolated neural crest stem cells from human hair follicles and induced them to differentiate into Schwann cells. Quantitative RT-PCR showed that microRNA(miR)-21 expression was gradually increased during the differentiation of neural crest stem cells into Schwann cells. After transfection with the miR-21 agonist(agomir-21), the differentiation capacity of neural crest stem cells was enhanced. By contrast, after transfection with the miR-21 antagonist(antagomir-21), the differentiation capacity was attenuated. Further study results showed that SOX-2 was an effective target of miR-21. Without compromising SOX2 mRNA expression, miR-21 can down-regulate SOX protein expression by binding to the 3′-UTR of miR-21 mRNA. Knocking out the SOX2 gene from the neural crest stem cells significantly reversed the antagomir-21 inhibition of neural crest stem cells differentiating into Schwann cells. The results suggest that miR-21 expression was increased during the differentiation of neural crest stem cells into Schwann cells and miR-21 promoted the differentiation through down-regulating SOX protein expression by binding to the 3′-UTR of SOX2 mRNA. | Yuxin Ni Kaizhi Zhang Xuejuan Liu Tingting Yang Baixiang Wang Li Fu Lan A Yanmin Zhou | 2014 | Neural Regeneration Research2014，9，8： | 9 |
| 3 | Serum outperforms plasma in small extracellular vesicle microRNA biomarker studies of adenocarcinoma of the esophagus显示文摘BACKGROUND Circulating microRNAs(miRNAs)are potential biomarkers for many diseases.However,they can originate from non-disease specific sources,such as blood cells,and compromise the investigations for miRNA biomarkers.While small extracellular vesicles(sEVs)have been suggested to provide a purer source of circulating miRNAs for biomarkers discovery,the most suitable blood sample for sEV miRNA biomarker studies has not been defined.AIM To compare the mi RNA profiles between matched serum and plasma s EV preparations to determine their suitability for biomarker studies.METHODS Matched serum and plasma samples were obtained from 10 healthy controls and10 patients with esophageal adenocarcinoma.s EV isolates were prepared from serum and plasma using Exo Quick TM and quantified using Nano Sight.RNA was extracted from s EV preparations with the mi RNeasy Serum/Plasma kit and profiled using the Taqman Openarray q PCR.The overall mi RNA content and theexpression of specific mi RNAs of reported vesicular and non-vesicular origins were compared between serum and plasma s EV preparations.The diagnostic performance of a previously identified multi-mi RNA biomarker panel for esophageal adenocarcinoma was also compared.RESULTS The overall mi RNA content was higher in plasma s EV preparations(480 mi RNAs)and contained 97.5%of the mi RNAs found in the serum s EV preparations(412 mi RNAs).The expression of commonly expressed mi RNAs was highly correlated(Spearman’s R=0.87,P<0.0001)between the plasma and serum s EV preparations,but was consistently higher in the plasma s EV preparations.Specific blood-cell mi RNAs(hsa-mi R-223-3 p,hsa-mi R-451 a,mi R-19 b-3 p,hsa-mi R-17-5 p,hsa-mi R-30 b-5 p,hsa-mi R-106 a-5 p,hsa-mi R-150-5 p and hsa-mi R-92 a-3 p)were expressed at 2.7 to 9.6 fold higher levels in the plasma s EV preparations compared to serum s EV preparations(P<0.05).In plasma s EV preparations,the percentage of protein-associated mi RNAs expressed at relatively higher levels(Ct 20-25)was greater than serum s EV preparations(50%vs 31%).While the percentage of vesicle-associated mi RNAs expressed at relatively higher levels was greater in the serum s EV preparations than plasma s EV preparations(70%vs 44%).A 5-mi RNA biomarker panel produced a higher cross validated accuracy for discriminating patients with esophageal adenocarcinoma from healthy controls using serum s EV preparations compared with plasma s EV preparations(AUROC 0.80 vs 0.54,P<0.05).CONCLUSION Although plasma s EV preparations contained more mi RNAs than serum s EV preparations,they also contained more mi RNAs from non-vesicle origins.Serum appears to be more suitable than plasma for s EV mi RNAs biomarkers studies. | Karen Chiam George C Mayne Tingting Wang David I Watson Tanya S Irvine Tim Bright Lorelle T Smith Imogen A Ball Joanne M Bowen Dorothy M Keefe Sarah K Thompson Damian J Hussey | 2020 | World Journal of Gastroenterology2020，26，20： | 1 |

| 6 | Hydroxyapatite reinforced inorganic-organic hybrid nanocomposite as high-performance adsorbents for bilirubin removal in vitro and in pig models显示文摘Highly efficient removal of bilirubin from whole blood directly by hemoperfusion for liver failure therapy remains a challenge in the clinical field due to the low adsorption capacity,poor mechanical strength and low biocompatibility of adsorbents.In this work,a new class of nanocomposite adsorbents was constructed through an inorganic-organic co-crosslinked nanocomposite network between vinyltriethoxysilane(VTES)-functionalized hydroxyapatite nanoparticles(V-Hap)and non-ionic styrene-divinylbenzene(PS-DVB)resins(PS-DVB/V-Hap)using suspension polymerization.Notably,our adsorbent demonstrated substantially improved mechanical performance compared to the pure polymer,with the hardness and modulus increasing by nearly 3 and 2.5 times,respectively.Moreover,due to the development of a mesoporous structure,the prepared PS-DVB/V-Hap3 exhibited an ideal adsorption capacity of 40.27 mg·g^(-1).More importantly,the obtained adsorbent beads showed outstanding blood compatibility and biocompatibility.Furthermore,in vivo extracorporeal hemoperfusion verified the efficacy and biosafety of the adsorbent for directly removing bilirubin from whole blood in pig models,and this material could potentially prevent liver damage and improve clinical outcomes.Taken together,the results suggest that PS-DVB/V-Hap3 beads can be used in commercial adsorption columns to threat hyperbilirubinemia patients through hemoperfusion,thus replacing the existing techniques where plasma separation is initially required. | Yamin Chai Zhuang Liu Yunzheng Du Lichun Wang Jinyan Lu Qian Zhang a Wenyan Han Tingting Wang Yameng Yu Lisha Sun Lailiang Ou | 2021 | Bioactive Materials2021，6，12： | 0 |
