Uptake of cholesterol by Tetrahymena thermophila is mainly due to phagocytosisLa captación de colesterol por Tetrahymena thermophila se realiza principalmente por fagocitosis
(Asociación Argentina de Microbiología, 2018-01)
The free-living ciliate Tetrahymena thermophila is a unicellular model organism in which landmark biological processes have been discovered, such as the first description of telomerase activity and the molecular structure ...
Bioconversion of egg cholesterol to pro-vitamin D sterols with Tetrahymena thermophila
(Wiley Blackwell Publishing, Inc, 2002-08)
The potential use of the non-pathogenic ciliate Tetrahymena thermophila for converting cholesterol into pro-vitamin D sterols in egg suspensions was investigated. Conditions screened for efficient conversion included ...
The Cryptosporidium parvum gp60 glycoprotein expressed in the ciliate Tetrahymena thermophila is immunoreactive with sera of calves infected with Cryptosporidium oocysts
(Elsevier Science, 2019-07)
Cryptosporidium parvum is a protozoan parasite of the phylum Apicomplexa responsible for cryptosporidiosis in calves, a disease that causes significant diarrhea and impairs gain of body weight, generating important production ...
Expression and functional characterization of a C-7 cholesterol desaturase from Tetrahymena thermophila in an insect cell line
(Elsevier Science Inc, 2015-02)
Tetrahymena thermophila transforms exogenous cholesterol into pro-vitamin D3 (7-dehydrocholesterol) with remarkable efficiency in a one-step reaction carried out by a C-7 cholesterol desaturase. The enzyme DES7 is encoded ...
Genome analysis of sphingolipid metabolism-related genes in Tetrahymena thermophila and identification of a fatty acid 2-hydroxylase involved in the sexual stage of conjugation
(Wiley Blackwell Publishing, Inc, 2020-11)
Sphingolipids are bioactive lipids present in all eukaryotes. Tetrahymena thermophila is a ciliate that displays remarkable sphingolipid moieties, that is, the unusual phosphonate-linked headgroup ceramides, present in ...
C-5(6) Sterol Desaturase from Tetrahymena thermophila: Gene Identification and Knockout, Sequence Analysis, and Comparison to Other C-5(6) Sterol Desaturases
(American Society for Microbiology, 2009-12)
The gene coding for a C-5(6) sterol desaturase in Tetrahymena thermophila, DES5A, has been identified by the knockout of the TTHERM_01194720 sequence. Macronucleus transformation was achieved by biolistic bombardment and ...
A Novel Sterol Desaturase-Like Protein Promoting Dealkylation of Phytosterols in Tetrahymena thermophila
(American Society For Microbiology, 2011-01)
The gene TTHERM_00438800 (DES24) from the ciliate Tetrahymena thermophila encodes a protein with three conserved histidine clusters, typical of the fatty acid hydroxylase superfamily. Despite its high similarity to sterol ...
Gene identification and functional characterization of a Δ12 fatty acid desaturase in Tetrahymena thermophila and its influence in homeoviscous adaptation to low temperature
(Elsevier Science, 2019-08)
Homeoviscous adaptation in poikilotherms is based in the regulation of the level of desaturation of fatty acids, variation in phospholipids head groups and sterol content in the membrane lipids, in order to maintain the ...
