The GGH/HuR Complex Binds and Stabilizes mRNAs to Maintain Tumor Cell Cycle and DNA Replication
Despite its canonical role in inhibiting DNA synthesis, GGH promotes tumor growth as a novel RNA‐binding protein. GGH binds GC‐rich 5′UTRs (e.g., CDC6/CCND1), recruits HuR to form a ternary complex that stabilizes mRNA via circular conformation, fueling DNA replication and the cell cycle. Targeting this axis suppresses NSCLC progression.

Aurora‐A Promotes Cell‐Cycle Progression From Quiescence Through Primary Cilia Disassembly
Our findings demonstrate that AurA facilitates cell cycle reentry by promoting primary cilia disassembly. Utilizing an inducible degron system, we showed that AurA depletion delays the G0/G1 transition, a defect rescued by forced deciliation. These results underscore AurA's role beyond mitosis and reinforce its potential as a therapeutic target in ...

Characterization of conserved arginine residues on Cdt1 that affect licensing activity and interaction with Geminin or Mcm complex [PDF]
All organisms ensure once and only once replication during S phase through a process called replication licensing. Cdt1 is a key component and crucial loading factor of Mcm complex, which is a central component for the eukaryotic replicative helicase. In

The oncogenic ETS factor ETV4 exerts a pleiotropic control over DNA replication both in a transcription‐dependent and ‐independent fashion in NSCLC cells. High‐ETV4 expression leads to R‐loop formation and DNA damage in response to TOP1 inhibition.

Ubiquitination of transcription factors in cancer: unveiling therapeutic potential
In cancer, dysregulated ubiquitination of transcription factors contributes to the uncontrolled growth and survival characteristics of tumors. Tumor suppressors are degraded by aberrant ubiquitination, or oncogenic transcription factors gain stability through ubiquitination, thereby promoting tumorigenesis.

Diverged composition and regulation of the Trypanosoma brucei origin recognition complex that mediates DNA replication initiation [PDF]
Initiation of DNA replication depends upon recognition of genomic sites, termed origins, by AAA+ ATPases. In prokaryotes a single factor binds each origin, whereas in eukaryotes this role is played by a six-protein origin recognition complex (ORC).

Significance Statement Plants regulate cell division to adapt growth to environmental changes. In Arabidopsis thaliana, AIP10 acts as a hub linking the cell cycle to primary metabolism. Its silencing increases cell division rates, enhances carbon fixation, and boosts metabolite accumulation, driving improved development and productivity. SUMMARY Plants

In eukaryotes, DNA replication is fired once in a single cell cycle before cell division starts to maintain stability of the genome. This event is tightly controlled by a series of proteins.

Role of WDHD1 in Human Papillomavirus-Mediated Oncogenesis Identified by Transcriptional profiling of E7-expressing cells [PDF]
The E7 oncoprotein of the high-risk human papillomavirus (HPV) plays a major role in HPV-induced carcinogenesis. E7 abrogates the G(1) cell cycle checkpoint and induces genomic instability, but the mechanism is not fully understood.

The epigenetic control of E-box and Myc-dependent chromatin modifications regulate the licensing of lamin B2 origin during cell cycle [PDF]
Recent genome-wide mapping of the mammalian replication origins has suggested the role of transcriptional regulatory elements in origin activation. However, the nature of chromatin modifications associated with such trans-factors or epigenetic marks ...
