犬小孢子菌SSH文庫中差異基因的研究
[Abstract]:Objective: Microsporum canis is a fungus that invades human and animal skin, hair, and armour. Its prominent biological characteristics are the horniness and the superficial infection of the skin. It is not an opportunistic pathogen, but a pathogenic bacteria that really infects the healthy body. With the improvement of people's living water, the pet and dog and other pets are in contact with humans. Microsporosis in dogs has increased year by year, especially the number of cases of psoriasis caused by Microsporum canis, and there is evidence that secretory protease plays an important role in their invasiveness. However, there is no report on the correlation between the protease except for the tinea capitis and the pathogenesis in the tinea capitis. The culture medium of canine microspore was cultured in the same inducible medium, that is, the culture medium strain (tester) of the children's scalp tissue, the culture medium strain (Driver1) of the smooth skin tissue of children, the culture medium strain (Driver2) of the adult scalp tissue, and the construction of tester with the suppression subtractive hybridization technique (suppression subtractive hybridization, SSH). Two positive differential gene libraries of Driver1 (SSH1 Library) and tester and Driver2 (SSH2 Library) were cloned. The further screening of the differential library and the functional and quantitative analysis of the differential genes were carried out in this experiment to explore the role of the differential gene in the pathogenesis of tinea pedis and the infection model of guinea pig in the next step. Research makes some explorations.
Method:
1. dot blot was used to screen positive clones of SSH1 and SSH2 libraries (all 250 clones).
2. the screened positive clones were sequenced and BLAST was used to analyze the homologous sequences on the GenBank and protein direct homologous cluster database (Clusters of Orthologous Groups of proteins, COG).
3. quantitative detection of differentially expressed genes by real-time PCR.
Result:
110 positive clones were obtained after 1. dot blot hybridization.
2. positive clones were sequenced: the SSH1 library obtained 62 effective sequences, and the SSH2 library obtained 44 effective sequences. The analysis of the database: removing the confounding gene (the homology 98%, linear fraction =200, and the linear fraction 40 of the fungal gene), 13 EST were obtained, 5 of which were unknown new sequences, which may represent a new tester specific expression. 8 of the genes found homologous genes, 6 of which have functional taxonomy.
3. the results of real-time PCR detection: the expression of FSH1 and PQ-LRP genes in the tester RNA pool is 44.6 times and 117 times in the Driver1 RNA pool, respectively. The expression of P-GAL4 and NADH1 genes in the SSH2 library is 78.2 times and 9.8 times that of the Driver1 RNA pool.
Conclusion:
1. the 5 homologous genes were screened in the SSH1 Library: FSH1, PQ-LRP, multidrug resistance protein MDR, RING zinc finger protein and RING, and 3 homologous genes were screened in the library.
The up-regulated expression of 2. FSH1 and PQ-LRP genes in the culture medium strain of children's scalp tissue induced culture medium showed that these 2 genes play an important role in the infection of the scalp tissue of Microsporum canis, which can be used as the molecular mechanism of tinea capitis caused by Microsporum canis.
The up-regulated expression of 3. P-GAL4 and NADH1 genes in the strains of adult scalp induced culture medium strains in children's scalp induced medium showed that these 2 genes may be more likely to be associated with the infection of children with Microspora canis, and can be used as a candidate gene for the study of the pathogenicity of microspore microspore.
