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 ...

Function of the upstream activating factor in chromatin structure organization and transcriptional regulation at the yeast ribosomal DNA

, 2010
Chromatin is the template of all processes involved in DNA metabolism in the eukaryotic cell. Accordingly, chromatin is a dynamic structure which changes in its composition and posttranslational modification correlating with the functional state of a ...

Chromatin remodeling enzyme Brg1 is required for mouse lens fiber cell terminal differentiation and its denucleation [PDF]

, 2010
Background: Brahma-related gene 1 (Brg1, also known as Smarca4 and Snf2 beta) encodes an adenosine-5'-triphosphate (ATP)-dependent catalytical subunit of the (switch/sucrose nonfermentable) (SWI/SNF) chromatin remodeling complexes.

Chromatin in 3D distinguishes dMes-4/NSD and Hypb/dSet2 in protecting genes from H3K27me3 silencing

Life Science Alliance, 2023
Histone KMTs of H3K36me maintains euchromatin by antagonizing H3K27me3 spreading and influencing 3D genome organization at TADs boundaries, thus participating in transcriptional program maintenance.

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.

NoRC, a novel chromatin remodeling complex involved in ribosomal RNA gene silencing [PDF]

, 2004
Regulation of gene expression takes place in the nucleus in a highly structured and condensed nucleoprotein environment, called chromatin (Felsenfeld and Groudine, 2003; Khorasanizadeh, 2004; Vaquero et al., 2003).

SUV family histone methyltransferases correlate with nuclear lamina remodeling and clinical outcome in cancer: integrative pan-cancer TCGA analysis and experimental evidence

Scientific Reports
Epigenetic regulation of chromatin structure is a key determinant of transcriptional control and nuclear organization in cancer. Among histone lysine methyltransferases, SUV39H1 and SUV39H2 catalyze the trimethylation of histone H3 lysine 9 (H3K9me3 ...

The Structure of Chromatin [PDF]

Proceedings of the National Academy of Sciences, 1971
The DNA in chromatin of isolated thymus nuclei, and in two different preparations of deoxyribonucleoprotein extracted from chromatin, has been digested with DNase. By variation of the time of reaction and the concentration of enzyme, and by comparison of the action of the enzyme on (protein-free) DNA with its action on DNA complexed with protein in ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
