Ancient and novel small RNA pathways compensate for the loss of piRNAs in multiple independent nematode lineages [PDF]

, 2015
Date of Acceptance: 02/01/2015Small RNA pathways act at the front line of defence against transposable elements across the Eukaryota. In animals, Piwi interacting small RNAs (piRNAs) are a crucial arm of this defence.

Cytoplasmic RNA-dependent RNA-synthesis in maturing chicken erythrocytes. [PDF]

, 1976
Includes bibliographical references.An RNA-dependent RNA polymerase from ribosomes of maturing chicken erythrocytes was investigated. Concurrent with an increase in globin and RNA synthesis during phenylhydrazine induced anaemia, the total and specific ...

On the Origin of Information Dynamics in Early Life

Life
We hypothesize that predictable variations in environmental conditions caused by night/day cycles created opportunities and hazards that initiated information dynamics central to life’s origin.

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Identification of novel components of Trypanosoma brucei editosomes [PDF]

, 2003
The editosome is a multiprotein complex that catalyzes the insertion and deletion of uridylates that occurs during RNA editing in trypanosomatids. We report the identification of nine novel editosome proteins in Trypanosoma brucei.

Citrus psorosis virus 24K protein inhibits the processing of miRNA precursors by interacting with components of the biogenesis machinery

Microbiology Spectrum
Sweet orange (Citrus sinensis) is one of the most important fruit crops worldwide. Virus infections in this crop can interfere with cellular processes, causing dramatic economic losses. By performing RT-qPCR analyses, we demonstrated that citrus psorosis

Precursors to small molecular weight RNA components [PDF]

FEBS Letters, 1975
Metabolically long-lived RNA components such as tRNA and rRNA are formed from unstable larger precursors [ 1,2] . Baby Hamster Kidney cells (BHK-2 1 cells) contain four small mol. wt RNA components (sm RNA) with a metabolic half-life of 5-7 days [3] . The size of these components (D, C, A, and L) was determined to be from 145 to 235 nucleotides based ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?
