Dynamic partitioning of a critical elongation factor between LEC and SEC regulates cellular snRNA and proliferation-related mRNA transcription

Nature Communications
Human RNA polymerase II (Pol II) regulates transcription of significant number of snRNA and proliferation-related mRNA genes by involving Little Elongation Complex (LEC) and Super Elongation Complex (SEC) respectively.

Fetal Muse-based therapy prevents lethal radio-induced gastrointestinal syndrome by intestinal regeneration

Stem Cell Research & Therapy, 2023
Background Human multilineage-differentiating stress enduring (Muse) cells are nontumorigenic endogenous pluripotent-like stem cells that can be easily obtained from various adult or fetal tissues.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Structure of the Nipah virus polymerase phosphoprotein complex

Nature Communications
The Nipah virus (NiV), a member of the Paramyxoviridae family, is notorious for its high fatality rate in humans. The RNA polymerase machinery of NiV, comprising the large protein L and the phosphoprotein P, is essential for viral replication. This study

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 ...

Mutant and Wild-Type Tumor Suppressor p53 Induces p300 Autoacetylation

iScience, 2018
Summary: The transcriptional co-activator p300 is essential for p53 transactivation, although its precise role remains unclear. We report that p53 activates the acetyltransferase activity of p300 through the enhancement of p300 autoacetylation ...

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 ...

ARTD10/PARP10 Induces ADP-Ribosylation of GAPDH and Recruits GAPDH into Cytosolic Membrane-Free Cell Bodies When Overexpressed in Mammalian Cells

Challenges, 2018
Protein ADP-ribosylation is a reversible post-translational modification of cellular proteins that is catalysed by enzymes that transfer one (mono) or several (poly) units of ADP-ribose from β-NAD+ to a specific amino acid of the target protein. The

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
