Nrf2 Drives Epigenetic Reprogramming and Acts as the Master Regulator of KLF4 Expression and Activity in Arsenic‐Induced Transformation

Advanced Science, EarlyView.
Nrf2 isn't just a protector—it's a driver of cancer stemness. The study uncovers how arsenic‐activated Nrf2 directly upregulates KLF4, a key pluripotency factor, fueling oncogenic reprogramming. Through enhancer activation and self‐reinforcing loop, Nrf2 and KLF4 co‐opt gene networks linked to epithelial‐to‐mesenchymal transition and tumor growth ...

An Interstitial 4q Deletion with a Mosaic Complementary Ring Chromosome in a Child with Dysmorphism, Linear Skin Pigmentation, and Hepatomegaly

Case Reports in Genetics, 2017
Interstitial deletions of 4q are rarely reported, vary in size, and have limited genotype-phenotype correlations. Here, genome-wide array CGH analysis identified a 21.6 Mb region of copy number loss at 4q12-q21.1 in a patient diagnosed with dysmorphism ...

A Prion‐Like Domain in EBV EBNA1 Promotes Phase Separation and Enables SRRM1 Splicing

Advanced Science, EarlyView.
This study discoveries that EBV EBNA1 behaves as a prion‐like protein, verified using cell‐based assays and the Saccharomyces cerevisiae Sup35p prion identification system. The prion‐like domain of EBNA1 drives liquid–liquid phase separation. EBNA1 interacts with the splicing factor SRSF1 to regulate the expression of the SRRM1 splicing isoforms ...

Single‐Cell Transcriptome Analysis Reveals That Hmga2 Regulates Neuroinflammation and Retinal Function by Modulating Müller Cell Autophagy Through PI3K/AKT Signaling Following MCAO‐Induced Retinal Ischemia

Advanced Science, EarlyView.
Employing snRNA‐seq post‐MCAO‐induced retinal ischemia (RI), this study revealed a novel Hmga2‐high Müller cell subpopulation. Hmga2 knockout alleviated neuroinflammation and RI symptoms, potentially by binding PI3K and regulating Müller cell autophagy.

Further delineation of complex chromosomal rearrangements in fertile male using multicolor banding

Molecular Cytogenetics, 2008
Background Complex chromosomal rearrangements (CCRs) are defined as structural chromosomal rearrangements with at least three breakpoints and exchange of genetic material between two or more chromosomes. Complex chromosomal translocations are rarely seen

FOXQ1 Regulates Brain Endothelial Mitochondrial Function by Orchestrating Calcium Signaling and Cristae Morphology

Advanced Science, EarlyView.
FOXQ1 emerges as a master transcriptional regulator of brain endothelial metabolism, orchestrating mitochondrial function through dual control of calcium signaling and cristae organization. This study reveals that brain endothelial cells rely on oxidative phosphorylation rather than glycolysis alone, challenging the current metabolic paradigm and ...

SENP6 Maintains Mitochondrial Homeostasis by Regulating Mitochondrial Protein Import Through deSUMOylation of TOM40

Advanced Science, EarlyView.
SUMOylation regulates mitochondrial processes, but its impact on protein import remains unclear. TOM40 is identified, a mitochondrial outer membrane channel protein, as a substrate of deSUMOylase SENP6. TOM40 SUMOylation disrupts outer membrane complex assembly, inhibits protein import, and compromises mitochondrial homeostasis.

Histone Lactylation‐Driven Upregulation of VRK1 Expression Promotes Stemness and Proliferation of Glioma Stem Cells

Advanced Science, EarlyView.
Glioblastoma (GBM) is the most aggressive primary brain tumor, with glioma stem cells (GSCs) driving treatment resistance. This study reveals that lactate promotes histone lactylation (H3K18la) at the VRK1 promoter, regulating GSC stemness and proliferation via the H3K18la/VRK1/YBX1/SOX2 pathway. The VRK1‐targeted nanoliposome A/TMZ‐siVRK1 demonstrates
