ABSTRACT

Abstract We aimed to analyze the expression profile of ACE2 and similar genes with ACE2, predict the number of variations in ACE2, detect the suspected SNPs on ACE2 gene, and perform the pathway analysis of renin-angiotensin system (RAS) and protein absorption-digestion. Moreover, we have predicted the gene-related diseases with ACE2. STRING was used to analyze functionally similar genes with ACE2. Exome Variant Server, SIFT, Polyphen2 were used to predict the number of variations in ACE2 and detect the suspected SNPs on ACE2. KEGG database and STRING were used to draw pathway of ACE2. Then, DISEASES resource, FitSNPs, UniProt, BioXpress, IGV Browser, Ensembl Genome Browser, and UCSC Genome Browser were used to predict the ACE2 gene-related diseases and expression profile in human normal and cancer tissues. We have shown that expression of ACE2 was correlated with AGT, REN, AGTR1, AGRT2, MME2, DPP4, PRCP, MEP1A, XPNPEP2, MEP1BandACE2 is expressed in testis, kidney, heart, thyroid, colon, esophagus, breast, minor salivary gland, pancreas, lung, liver, bladder, cervix, and muscle tissues. We found 99 variations in ACE2 gene, in which no previous study has been performed. In the future, this in silico analysis should be combined with other pieces of evidence including experimental data to assign function.

ABSTRACT

The Wistar rats ( 9 weeks old, 180­200 g body weight) used in these trials were divided into two groups of 16 animals each (Control group and Experimental group). 100x65x100 in the sizes of the experimental group were taken into a glass vase. During the time period of 8 weeks, 5 days a week with 8 hours the inhalation of 10 ppm formaldehyde was made. Skin was removed and placed in 10% formaline. Sections were stained with Hematoxylene-Eosine, Trichrome-Masson and observed under light microscope. In this study, histopathological and immunohistochemical techniques due to the impact of the changes in formaldehyde and examined the distribution of vimentin.


En este ensayo se utilizaron ratas Wistar (9 semanas de edad, 180-200 g de peso corporal) que se dividieron en dos grupos de 16 animales cada uno (grupos control y experimental). Los animales del grupo experimental fueron colocados en un vaso de vidrio de tamaño 100x65x100. Durante un período de tiempo de 8 semanas, 5 días a la semana con 8 horas se expuso a la inhalación de 10 ppm de formaldehído. Se retiró la piel y se colocó en formalina al 10%. Las secciones fueron teñidas con Hematoxilina-Eosina y Tricrómico de Masson, y fueron observadas al microscopio óptico. Las técnicas histopatológicas e inmunohistoquímicas y el impacto en la piel provocado por el formaldehído permitieron examinar la expresión de vimentina.
