Shared dysregulation of complement and phosphorylation pathways in the cerebrospinal fluid of encephalitis, Aicardi–Goutières syndrome, and autism

Developmental Medicine &Child Neurology, EarlyView.
Abstract Aim To identify shared and disorder‐specific molecular alterations across encephalitis, Aicardi–Goutières syndrome (AGS), and autism spectrum disorder (ASD) using cerebrospinal fluid (CSF) proteomics. Method In this cross‐sectional case–control study, mass‐spectrometry‐based proteomics was performed on archived CSF samples collected between ...

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

The FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

TOP1MT rs2293925 is an enhancer‐active regulatory SNP that shapes mitochondrial R‐loop dynamics

The FEBS Journal, EarlyView.
This study shows how a common genetic variant of mitochondrial topoisomerase 1 (TOP1MT rs2293925) can influence mitochondrial gene regulation, DNA topology, and formation of noncanonical nucleic acid structures such as R‐loops. By linking this enhancer‐active variant to mitochondrial nucleic acid stress in cellular contexts relevant to amyotrophic ...

Ploidy‐dependent modulation of DNA replication kinetics in Xenopus

The FEBS Journal, EarlyView.
Using an interspecies replication system with Xenopus frog species of different ploidy levels, we investigated how DNA replication adapts to polyploidization. While replication was slower in tetraploid than in diploid nuclei, dodecaploid nuclei unexpectedly replicated faster than tetraploid nuclei. Our findings show that increasing genome size does not

A guide to transcriptional cyclin‐dependent kinases in cancer

The FEBS Journal, EarlyView.
Transcriptional cyclin‐dependent‐kinases (tCDKs) facilitate gene expression by promoting RNA polymerase II (RNAPII) progression through discrete phases of the transcription cycle. Aberrant tCDK activity is detectable in different human cancers, thereby contributing to de‐regulated gene expression programs that drive oncogenic phenotypes.
