Evidence for regulated expression of Telomeric Repeat-containing RNAs (TERRA) in parasitic trypanosomatids [PDF]

, 2017
The Telomeric Repeat-containing RNAs (TERRA) participate in the homeostasis of telomeres in higher eukaryotes. Here, we investigated the expression of TERRA in Leishmania spp.

Phytochemical and Biological Evaluation of Leaves, Stems, and Roots of Schinus weinmanniifolia Mart. Ex Engl.

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
Ethanolic extracts from leaves, stems, and roots of Schinus weinmanniifolia Mart. ex Engl. were evaluated for phytochemical composition and biological activities. The extracts exhibited antioxidant, photoprotective, and antimicrobial activity, without hemolytic effects or cytotoxicity at active concentrations. Syringic acid, epicatechin, and rutin were

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

The FEBS Journal, Volume 293, Issue 6, Page 1681-1707, March 2026.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Developing giant plasma membrane vesicles from Leishmania cells to investigate the role of membrane proteins in photodynamic inactivation

Photochemistry and Photobiology, Volume 102, Issue 2, Page 480-488, March/April 2026.
In this study, we developed giant plasma membrane vesicles (GPMVs) from Leishmania amazonensis promastigote membranes to investigate the role of protein‐embedded membranes in methylene blue (MB) photooxidation. Upon MB photoactivation in model lipid membranes (giant unilamellar vesicles, GUVs), a distinct photooxidation effect was observed, marked by ...
