The study was conducted to explore the potential different characters between Blue-shelled chicken and White leghorn.Global genome microRNA was combined the identified microRNA with complementary lab-predicted microRNA.Then the two breed chicken's SNP data got by GGRS were mapped to the microRNA and focused on SNP that deliberately located in mature-microRNA.Bioinformatics method was adopted for target prediction on microRNA which had SNPs.By further gene enrichment analysis,the study found these genes enriched in 22 GO terms,10 KEGG pathways,and 3 IPA important networks.And they enriched in traits which associated with growth,such as mTOR signaling pathways,Wnt signaling pathways,growth hormone receptor networks and insulin-like growth factor Ⅰ receptor networks.And they also enriched in some laying traits,such as oocyte meiotic signaling pathways and progesterone mature oocytes signaling pathways.The methods and the results might provide references for further studies. 相似文献
In order to investigate the effect of AIR on inflammatory reaction infected by Brucellamelitensis (16M), the AIR domain of Tecpr1 gene of murine macrophages RAW264.7 were knocked down (I-A), overexpressed (O-A) and reversed (OA-IA). Using the chlorine fluorescein (DCFH-DA) as a probe, we detected the variation of ROS production and mitochondria distribution by confocal laser scanning microscopy. We observed the expression changes of NLRP3, ASC and Caspase-1 by qRT-PCR and the expression changes of IL-18,IL-1β and Caspase-1 in host cells by ELISA. The results showed that 16M could stimulate RAW264.7 cells to produce ROS by time-dependent pathway, and I-A group and O-A group showed more abnormal accumulation of mitochondrial. The results of qRT-PCR and ELISA suggested that it had effect on the expression levels of NLRP3, ASC,Caspase-1 and IL-18, IL-1β and Caspase-1 in cells of different groups. Those results indicated that with AIR gene deletion, the release amount of ROS changed, mitochondrial clustered abnormally, and AIR was closely related to the activation of inflammasomes and induction of inflammatory reactions. 相似文献
To study the effect of luteolin on blood indexes,liver and kidney in mice with acute mercury poisoning,28 mice were randomly divided into four groups:Control group (intraperitoneal injection 0.9% saline),luteolin group (lavage 100 mg/kg luteolin),mercuric chloride group (intraperitoneal injection 4 mg/kg mercury chloride) and mercury chloride+luteolin group (intraperitoneal injection 4 mg/kg mercuric chloride,lavage 100 mg/kg luteolin).The activities of ALT in serum,AST,CREA and BUN contents,blood WBC,RBC,HGB content and GSH and MDA contents of liver tissue were detected.Morphological changes of liver and kidney tissues were observed.The results showed that compared with the control group,the activities of ALT and AST of mercuric chloride group were extremely significantly increased (P < 0.01),serum CREA,BUN,blood WBC and liver tissue MDA contents were significantly increased (P < 0.05) while blood RBC,HGB and liver tissue GSH contents were significantly decreased (P < 0.05).Liver,kidney pathological changes were obviously.Compared with mercuric chloride group,the activities of ALT,AST in serum,CREA,BUN,blood WBC and liver tissue MDA contents of mercuric chloride+luteolin group were significantly decreased (P < 0.05),while blood RBC,HGB and liver tissue GSH contents were significantly elevated (P < 0.05).Liver,kidney pathological changes were attenuated obviously.The poisoning were characterized by inflammation and the occurrence of anemia when acute mercury poisoning occurred,liver and kidney showed different degrees of injury in mice.Luteolin could reduce the toxic effects of acute mercury poisoning on blood,liver and kidney. 相似文献
