Fecha de publicación: | 4-jul-2022 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | Pathogens 11 (7) 761 (2022) | Resumen: | The compartmentalization of untranslated mRNA molecules in granules occurring in many eukaryotic organisms including trypanosomatids involves the formation of complexes between mRNA molecules and RNA-binding proteins (RBPs). The putative ATP-dependent DEAD/H RNA helicase (DEVH1) from Leishmania infantum (Kinetoplastida: Trypanosomatidae) is one such proteins. The objective of this research is finding differentially expressed genes in a stable episomal transfectant L. infantum promastigote line over-expressing DEVH1 in the stationary phase of growth in axenic culture to get insight into the biological roles of this RNA helicase in the parasite. Interestingly, genes related to parasite survival and virulence factors, such as the hydrophilic surface protein/small hydrophilic endoplasmic reticulum protein (HASP/SHERP) gene cluster, an amastin, and genes related to reactive oxygen species detoxification are down-regulated in DEVH1 transfectant promastigotes. | Descripción: | 15 p.-4 fig.-1 tab. | Versión del editor: | https://doi.org/10.3390/pathogens11070761 | URI: | http://hdl.handle.net/10261/297192 | DOI: | 10.3390/pathogens11070761 | E-ISSN: | 2076-0817 |
