State‐of‐the‐Art Strategies for Circular RNA in Cancers: Opportunity and Challenge

MedComm, Volume 7, Issue 2, February 2026.
Overview of circular RNA in tumors. ABSTRACT Circular RNAs (circRNAs) are characterized by their covalently closed structure, remarkable stability, and precise spatiotemporal regulation, evolving from once‐overlooked transcriptional byproducts to pivotal molecular regulators.

Estrogen receptor alpha (ERα) regulates PARN-mediated nuclear deadenylation and gene expression in breast cancer cells

RNA Biology
The estrogen signalling pathway is highly dynamic and primarily mediated by estrogen receptors (ERs) that transcriptionally regulate the expression of target genes.

Deciphering mRNA Translation During Sperm Capacitation: A New Frontier in Fertility Research

Molecular Reproduction and Development, Volume 93, Issue 2, February 2026.
ABSTRACT Male infertility accounts for approximately 50% of infertility cases, with nearly 30% remaining unexplained after standard evaluations. This highlights the need for a better understanding of sperm function to advance diagnostic and therapeutic strategies. Sperm were long considered translationally quiescent; however, emerging evidence suggests

The CCR4–NOT deadenylase complex safeguards thymic positive selection by down-regulating aberrant pro-apoptotic gene expression

Nature Communications, 2020
The CCR4-NOT complex catalyzes mRNA deadenylation and hence regulates protein translation. Here the authors show that CNOT3 regulation of this complex is needed for positive selection of thymocytes via a mechanism involving inhibition of pro-apoptotic ...

The role of the E3 ligase Not4 in cotranslational quality control

Frontiers in Genetics, 2014
Cotranslational quality control (QC) is the mechanism by which the cell checks the integrity of newly synthesized proteins and mRNAs. In the event of mistakes these molecules are degraded.

The E3 ubiquitin ligase, RNF219, suppresses CNOT6L expression to exhibit antiproliferative activity

FEBS Open Bio
Despite the increasing evidence of the role of CCR4‐NOT complex in posttranscriptional gene regulation, relatively little is known about its mode of action. In a search for novel CCR4‐NOT interacting partners, we carried out mass spectrometry analysis of

Reconstitution of recombinant human CCR4-NOT reveals molecular insights into regulated deadenylation

Nature Communications, 2019
The CCR4-NOT complex shortens poly(A) tails of messenger RNAs. By biochemical reconstitution of the entire human CCR4-NOT complex, the authors show the stimulatory roles of non-enzymatic subunits and the importance of the interaction between CAF40 and ...
