Prefrontal cortex miR-29b-3p plays a key role in the antidepressant-like effect of ketamine in rats
Yun-Qiang Wan,Jian-Guo Feng,Mao Li,Mao-Zhou Wang,Li Liu,Xueru Liu,Xiao-Xia Duan,Chun-Xiang Zhang,Xiao-Bin Wang 생화학분자생물학회 2018 Experimental and molecular medicine Vol.50 No.-
Ketamine has a rapid, obvious, and persistent antidepressant effect, but its underlying molecular mechanisms remain unknown. Recently, microRNAs (miRNAs) have emerged as important modulators of ketamine’s antidepressant effect. We investigated the alteration in miR-29b-3p in the brain of rats subjected to ketamine administration and chronic unpredictable mild stress (CUMS), and a sucrose preference test and forced swimming test were used to evaluate the rats’ depressive-like state. We used recombination adeno-associated virus (rAAV) or lentivirus-expressing miR-29b-3p to observe the change in metabotropic glutamate receptor 4 (GRM4). Cell culture and electrophysiological recordings were used to evaluate the function of miR-29b-3p. Ketamine dramatically increased miR-29b-3p expression in the prefrontal cortex of the normal rats. The dual luciferase reporter test confirmed that GRM4 was the target of miR-29b- 3p. The miR-29b-3p levels were downregulated, while the GRM4 levels were upregulated in the prefrontal cortex of the depressive-like rats. The ketamine treatment increased miR-29b-3p expression and decreased GRM4 expression in the prefrontal cortex of the depressive-like rats and primary neurons. By overexpressing and silencing miR-29b-3p, we further validated that miR-29b-3p could negatively regulate GRM4. The silencing of miR-29b-3p suppressed the Ca2+ influx in the prefrontal cortex neurons. The miR-29b-3p overexpression contributed to cell survival, cytodendrite growth, increases in extracellular glutamate concentration, and cell apoptosis inhibition. The overexpression of miR- 29b-3p by rAAV resulted in a noticeable relief of the depressive behaviors of the CUMS rats and a lower expression of GRM4. The miR-29b-3p/GRM4 pathway acts as a critical mediator of ketamine’s antidepressant effect in depressive-like rats and could be considered a potential therapeutic target for treating major depression disorder.

Genome-wide association studies approach and post-GWAS study in rice
Gang Li,Min-Young Yoon,Won-Hee Ra,Jae-Wan Park,Qiang He,Aye Aye Khaing,Xiao-Qiang Wang,Win Htet Oo,Feng-Peng Li,Byoung Kook Yun,Chang-Yong Lee,Yong-Jin Park 한국육종학회 2013 한국육종학회 심포지엄 Vol.2013 No.07
AGenome-wide association studies (GWAS) have proven a useful technique for identifying genetic loci responsible for natural variation in rice. With the fast developed next-generation sequencing technology, it is possible for people to carry out GWAS by phenotyping different traits. However, how to make full use of huge data, abandon unnecessary data, and solve the problem of data application effectively seems still an obstacle for many researchers. Taking the case of whole-genome resequencing of Korean authentic rice core set, here we present a general technological path of GWAS including: 1) a schematic view of sequencing-based GWAS in rice; 2) a user-friendly and interactive web application for GWAS in rice by the aid of experience from Arabidopsis; 3) Haplotype and association analysis of candidate genes in a certain mechanism pathway, giving 10 starch synthesis genes as example; and 4) functional validation by Trans- and Mata-Omics analysis.
