Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Ciz1 cooperates with cyclin-A-CDK2 to activate mammalian DNA replication in vitro [PDF]

, 2010
Initiation of mammalian DNA replication can be reconstituted from isolated G1-phase nuclei and cell extracts, supplemented with cyclin-dependent protein kinases (CDKs).

Both Chromosome Decondensation and Condensation Are Dependent on DNA Replication in C.elegans Embryos [PDF]

, 2015
During cell division, chromatin alternates between a condensed state to facilitate chromosome segregation and a decondensed form when DNA replicates.

Priming agents transiently reduce the clearance of cell-free DNA to improve liquid biopsies

Science
Liquid biopsies enable early detection and monitoring of diseases such as cancer, but their sensitivity remains limited by the scarcity of analytes such as cell-free DNA (cfDNA) in blood.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

DNA damage responses in the context of the cell division cycle [PDF]

, 2010
During my PhD, I have investigated aspects of the DNA damage response (DDR) in the context of three different cellular scenarios: DNA damage signalling in response to double-strand breaks during mitosis, coordination of DNA replication with DNA damage ...

Utility of plasma cell‐free DNA in metastatic castration‐resistant prostate cancer

IJU Case Reports, 2020
Introduction Cell‐free DNA is suggested as a prognostic biomarker in metastatic castration‐resistant prostate cancer. However, it remains unknown which parameter of cell‐free DNA is correlated with the progression and prognosis of metastatic castration ...

Liquid Biopsy Based on Cell-Free DNA and RNA.

Annual Review of Biomedical Engineering
This review delves into the rapidly evolving landscape of liquid biopsy technologies based on cell-free DNA (cfDNA) and cell-free RNA (cfRNA) and their increasingly prominent role in precision medicine.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Direct Involvement of Retinoblastoma Family Proteins in DNA Repair by Non-homologous End-Joining. [PDF]

, 2015
Deficiencies in DNA double-strand break (DSB) repair lead to genetic instability, a recognized cause of cancer initiation and evolution. We report that the retinoblastoma tumor suppressor protein (RB1) is required for DNA DSB repair by canonical non ...
