The secret life of RNA and lipids

RNA Biology
There is no life without RNA or lipids. But could there be life with only RNA and lipids? The discovery that RNA can catalyse reactions in addition to encoding information opened new directions for engineering life and the possibility of life emerging ...

Melting transitions in biomembranes

, 2019
We investigated melting transitions in biological membranes in their native state that include their membrane proteins. These membranes originated from \textit{E. coli}, \textit{B.

Nanoporous silica-based protocells at multiple scales for designs of life and nanomedicine. [PDF]

, 2015
Various protocell models have been constructed de novo with the bottom-up approach. Here we describe a silica-based protocell composed of a nanoporous amorphous silica core encapsulated within a lipid bilayer built by self-assembly that provides for ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Identification of phosphatidylserylglutamate: a novel minor lipid in Escherichia coli

Journal of Lipid Research, 2009
Advances in mass spectrometry have facilitated the identification of novel lipid structures. In this work, we fractionated the lipids of Escherichia coli B and analyzed the fractions using negative-ion electrospray ionization mass spectrometry to reveal ...

Lipid bilayer properties potentially contributed to the evolutionary disappearance of betaine lipids in seed plants

BMC Biology, 2023
Background Many organisms rely on mineral nutrients taken directly from the soil or aquatic environment, and therefore, developed mechanisms to cope with the limitation of a given essential nutrient.

Influence of consumption of high oleic sunflower oil on the biosynthesis of fatty acids in the liver of rats

Journal of Education, Health and Sport, 2022
Background. To determine the effect of consumption of high-oleic sunflower oil on the content and biosynthesis of energy and polyunsaturated (PUFA) fatty acids in rat liver lipids. Methods. Rats received a semi-synthetic fat-free diet in which 5 % or

Synthetic functional π-stack architecture in lipid bilayers

Org. Biomol. Chem., 2006
Neglected until recently, pi-stack architecture is rapidly emerging as a powerful strategy to create function in lipid bilayer membranes. Recent reports describe supramolecular rosettes acting as hosts of intercalating guests, to assemble in bilayer membranes and, in the case of stacked guanosine and folate quartets, to form ion channels.

Effects of organic plant oils and role of oxidation on nutrient utilization in juvenile rainbow trout (Oncorhynchus mykiss) [PDF]

, 2012
The study compared the effect of four either fresh or force oxidized organic plant oils in diets for juvenile rainbow trout (Oncorhynchus mykiss) in which 47% of conventional LT fish meal protein was substituted by a mixture of 3 organic plant protein ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
