HDAC6 and USP9X Control Glutamine Metabolism by Stabilizing GS to Promote Glioblastoma Tumorigenesis

Advanced Science, EarlyView.
Glioblastoma (GBM) growth relies on glutamine synthetase (GS), which is stabilized by histone deacetylase 6 (HDAC6) and deubiquitinated by ubiquitin‐specific peptidase 9, X‐linked (USP9X). HDAC6 promotes GS deacetylation, while USP9X removes its K48‐linked polyubiquitination, enhancing GS stability.

Chromosomal mapping reveals a dynamic organization of the histone genes in aphids (Hemiptera: Aphididae) [PDF]

, 2013
Despite their involvement in different processes, histone genes have been analysed in few insects. In order to improve the knowledge about this important gene family, genes coding for histones have been analysed in the aphid Acyrthosiphon pisum showing ...

Attenuated Nuclear Tension Regulates Progerin‐Induced Mechanosensitive Nuclear Wrinkling and Chromatin Remodeling

Advanced Science, EarlyView.
The premature aging‐related progerin leads to defective nuclear morphology and is associated with disrupted molecular coupling between the extranuclear cytoskeleton and lamin‐associated nuclear envelope. It is discovered that progerin expression reduces nuclear tension, forms nuclear wrinkling, and enhances chromatin dynamics, thereby regulating ...

Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa

Advanced Science, EarlyView.
Sesbania, a leguminous halophyte, thrives in saline soils. Comparative genomics reveals key genomic variations—particularly chromosomal inversions—are identified as contributors to population differentiation and salt resilience. These findings advance the understanding of genomic variation driving evolution and phenotypic differentiation and offer ...

Loss of STARD7 Triggers Metabolic Reprogramming and Cell Cycle Arrest in Breast Cancer

Advanced Science, EarlyView.
Breast cancer cells undergo metabolic and transcriptomic reprogramming to support aberrant cell proliferation. Their mitochondria rely on the transfer of phosphatidylcholine from the endoplasmic reticulum to their membranes by STARD7, a candidate upregulated in breast cancer, to be functional.

Neuronal FGF13 Inhibits Mitochondria‐Derived Damage Signals to Prevent Neuroinflammation and Neurodegeneration in a Mouse Model of Parkinson's Disease

Advanced Science, EarlyView.
This study elucidates a novel role of FGF13 in manipulating neuronal fate via mitochondrial transfer. FGF13 is identified as a mitochondria‐stabilizing protein by interacting with mitochondrial proteins. Under stress, the decrease of neuronal FGF13 fails to retain mitochondria within the cytoplasm, leading to the release of damaged mitochondria to ...

SNORA74A Drives Self‐Renewal of Liver Cancer Stem Cells and Hepatocarcinogenesis Through Activation of Notch3 Signaling

Advanced Science, EarlyView.
Abstract Liver cancer stem cells (CSCs) account for tumor initiation, heterogeneity and therapy resistance. However, the role of small nucleolar RNAs (snoRNAs) in the regulation of liver CSCs remains largely unclear. Here, this work identifies a conserved H/ACA box snoRNA SNORA74A which is highly expressed in liver CSCs.

Dynamic methylation of alfalfa histone H3.

Journal of Biological Chemistry, 1993
Dynamic lysine methylation of histone H3 in alfalfa tissue culture cells was studied by labeling with tritiated methionine, purification of variants H3.1 and H3.2 by reversed-phase high pressure liquid chromatography and amino acid analysis. Mono- and dimethyl-L-lysine were the major labeled amino acids. Within 100 h of continued growth conversion from

Nickel binding sites in histone proteins [PDF]

, 2012
Nickel compounds are well known as human carcinogens, though the molecular events that are responsible for this are not well understood. It has been proposed that a crucial element in the mechanism of carcinogenesis is the binding of Ni(II) ions within

Akkermansia Muciniphila Alleviates Severe Acute Pancreatitis via Amuc1409‐Ube2k‐Foxp3 Axis in Regulatory T Cells

Advanced Science, EarlyView.
Akkermansia depletion correlates with acute pancreatitis (AP) severity. A. muciniphila and its protein Amuc_1409 mitigate pancreatic/systemic inflammation by expanding Tregs and IL‐10. Mechanistically, Amuc_1409 binds Ube2k, inhibiting Foxp3 ubiquitination to stabilize Treg differentiation and IL‐10 production, countering SAP‐induced SIRS/CARS ...
