Tetraether archaeal lipids promote long-term survival in extreme conditions. [PDF]
Mol MicrobiolAbstractThe sole unifying feature of the incredibly diverse Archaea is their isoprenoid‐based ether‐linked lipid membranes. Unique lipid membrane composition, including an abundance of membrane‐spanning tetraether lipids, impart resistance to extreme conditions.

Functionalized Membrane Domains: An Ancestral Feature of Archaea?
Frontiers in Microbiology, 2020 Bacteria and Eukarya organize their plasma membrane spatially into domains of distinct functions. Due to the uniqueness of their lipids, membrane functionalization in Archaea remains a debated area. A novel membrane ultrastructure predicts that monolayer

Stabilized tetraether lipids based particles guided prophyrins photodynamic therapy [PDF]
Drug Delivery, 2018 Photodynamic therapy (PDT) that involves ergonomically delivered light in the presence of archetypical photosensitizer such as Protoporphyrin IX (PpIX) is a time-honored missile strategy in cancer therapeutics. Yet, the premature release of PpIX is one of the most abundant dilemma encounters the therapeutic outcomes of PDT due to associated toxicity ...

Energy flux controls tetraether lipid cyclization in Sulfolobus acidocaldarius [PDF]
Environmental Microbiology, 2019 Summary Microorganisms regulate the composition of their membranes in response to environmental cues. Many Archaea maintain the fluidity and permeability of their membranes by adjusting the number of cyclic moieties within the cores of their glycerol dibiphytanyl glycerol tetraether (GDGT) lipids.

Transport of branched tetraether lipids from the Tagus River basin to the coastal ocean of the Portuguese margin: consequences for the interpretation of the MBT’/CBT paleothermometer [PDF]
, 2014 Branched glycerol dialkyl glycerol tetraethers (brGDGTs), which are transported from soil to marine sediment by rivers, have been used to reconstruct the mean annual air temperature (MAAT) and soil pH of the drainage basin using the methylation index of ...

Short-term variability in the sedimentary BIT index of Lake Challa, East Africa over the past 2200 years : validating the precipitation proxy [PDF]
, 2015 . The branched vs. isoprenoid index of tetraethers (BIT index) in Lake Challa sediments has been applied as a monsoon precipitation proxy on the assumption that the primary source of branched tetraether lipids (brGDGTs) was soil washed in from the lake's

Temperate Oligocene surface ocean conditions offshore of Cape Adare, Ross Sea, Antarctica [PDF]
Climate of the Past, 2021 Antarctic continental ice masses fluctuated considerably during the Oligocene “coolhouse”, at elevated atmospheric CO2 concentrations of ∼600–800 ppm. To assess the role of the ocean in the Oligocene ice sheet variability, reconstruction of past ocean ...
