In eukaryotic cells, cytoplasmic mRNA is characterised by a 3′ poly(A) tail. The shortening and removal of poly(A) tails (deadenylation) by the Ccr4‐Not nuclease complex leads to reduced translational efficiency and RNA degradation.

Effect of Larval Nutrition on Maternal mRNA Contribution to the Drosophila Egg. [PDF]
Embryonic development begins under the control of maternal gene products, mRNAs and proteins that the mother deposits into the egg; the zygotic genome is activated some time later. Maternal control of early development is conserved across metazoans. Gene

Mapping malignant T‐cell states and immune circuits in Sézary syndrome by single‐cell analysis
Peripheral blood single‐cell RNA‐seq from leukaemic CTCL defined three malignant T‐cell programmes: MTC CM, MTC Reg and MTC E/EM, each with distinct features and candidate vulnerabilities. For example, inferred immune circuits highlighted actionable IL‐10/JAK–TYK2–STAT3 signalling, KIR–MHC I inhibitory interactions and myeloid/B‐cell inflammatory and ...

Interaction of antiproliferative protein Tob with the CCR4‐NOT deadenylase complex
Tob protein, when overexpressed, suppresses growth of NIH3T3 cells, presumably by regulating expression of various growth‐related genes. However, the molecular mechanisms underlying Tob‐mediated regulation of gene expression have been obscure. To address this issue we established stable Tob‐expressing cell lines and used a proteomics approach to ...

Systematic analysis of the role of RNA-binding proteins in the regulation of RNA stability. [PDF]
mRNA half-lives are transcript-specific and vary over a range of more than 100-fold in eukaryotic cells. mRNA stabilities can be regulated by sequence-specific RNA-binding proteins (RBPs), which bind to regulatory sequence elements and modulate the ...

The rice protein OsFKBP20‐1b protects key RNA‐surveillance factors from breakdown, so they can better eliminate defective messages. This RNA quality‐control boost reduces errors and helps plants survive drought, revealing a link between RNA control and drought tolerance.

Structural and biochemical characterization of eukaryotic mRNA decapping activators [PDF]
In eukaryotes, mRNA turnover starts with the truncation of 3′ poly(A) tail and proceeds with either 3′-to-5′ degradation by the exosome complex or with decapping followed by 5′-to-3′ degradation by Xrn1.

The 3' to 5' exoribonuclease DIS3: from structure and mechanisms to biological functions and role in human disease [PDF]
DIS3 is a conserved exoribonuclease and catalytic subunit of the exosome, a protein complex involved in the 3’ to 5’ degradation and processing of both nuclear and cytoplasmic RNA species.

ABSTRACT Plant viruses drive widespread crop epidemics, yet the host plant responses across different cell types, particularly how these responses are influenced by cultivars with varying genetic backgrounds, including the presence of resistance (R) genes, remain poorly understood. Using tomato brown rugose fruit virus (ToBRFV) and two tomato cultivars,
