Bioinformatics and expression analysis of the Xeroderma Pigmentosum complementation group C (XPC) of Trypanosoma evansi in Trypanosoma cruzi cells. BRAZ J BIOL 2021; 83:e243910. [PMID: 34190757 DOI: 10.1590/1519-6984.243910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2020] [Accepted: 03/23/2021] [Indexed: 11/22/2022] Open
Abstract
Nucleotide excision repair (NER) acts repairing damages in DNA, such as lesions caused by cisplatin. Xeroderma Pigmentosum complementation group C (XPC) protein is involved in recognition of global genome DNA damages during NER (GG-NER) and it has been studied in different organisms due to its importance in other cellular processes. In this work, we studied NER proteins in Trypanosoma cruzi and Trypanosoma evansi, parasites of humans and animals respectively. We performed three-dimensional models of XPC proteins from T. cruzi and T. evansi and observed few structural differences between these proteins. In our tests, insertion of XPC gene from T. evansi (TevXPC) in T. cruzi resulted in slower cell growth under normal conditions. After cisplatin treatment, T. cruzi overexpressing its own XPC gene (TcXPC) was able to recover cell division rates faster than T. cruzi expressing TevXPC gene. Based on these tests, it is suggested that TevXPC (being an exogenous protein in T. cruzi) interferes negatively in cellular processes where TcXPC (the endogenous protein) is involved. This probably occurred due interaction of TevXPC with some endogenous molecules or proteins from T.cruzi but incapacity of interaction with others. This reinforces the importance of correctly XPC functioning within the cell.

Bianchi TF, Jeske S, Grala APDP, Leon IFD, Bedin C, Mello FD, Silva GCCD, Villela MM. Current situation of Chagas disease vectors (Hemiptera, Reduviidae) in Southern Rio Grande do Sul State, Brazil. Rev Inst Med Trop Sao Paulo 2021; 63:e47. [PMID: 34161553 PMCID: PMC8216688 DOI: 10.1590/s1678-9946202163047] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Accepted: 05/11/2021] [Indexed: 11/22/2022] Open
Abstract
Chagas disease (CD) has been considered endemic in the South of Rio Grande do Sul
(RS) State, Brazil. This study aimed at evaluating the occurrence of
Trypanosoma cruzi vectors based on the main species
captured in Southern Rio Grande do Sul State from 2008 to 2019. The study area
comprised counties that belong to the 3rd Regional Health
Coordination (RHC) and to the 7th RHC, whose headquarters are in
Pelotas and Bage, respectively. The study was based on secondary data provided
by the partnership between the Federal University of Pelotas, Rio Grande do Sul
State (UFPel-RS) and the State Health Surveillance Center in RS (SCHS-RS). One
thousand and four hundred triatomines were captured in the area supervised by
the 3rd RHC, mainly in Cangucu (37.7%), Piratini (22.4%) and Pinheiro
Machado (15.1%), while, in the area supervised by the 7th RHC, the
largest number of triatomines was captured in Lavras do Sul (64.15%). In both
areas, Triatoma rubrovaria (90.6%) and Panstrongylus
tupynambai (7.4%) were the most common species. Most were captured
inside households but T. cruzi-positive insects were not found
in the period under study. The results of this study show that, in Southern Rio
Grande do Sul State, there is still a high rate of triatomine household invasion
and dispersal, mainly by T. rubrovaria. Thus, the entomological
surveillance should be maintained with the participation of the population and
further studies should be deepened in the area.
