Proton FLASH Exposure Preserves Gut Commensal Microbiomes and Spares Intestinal Stem Cells

Advanced Science, Volume 13, Issue 31, 4 June 2026.
This study highlights the role of Proton FLASH abdominal irradiation in sparing of intestinal stem cells and preservation of key gut microbial population resulting minimization of radiation toxicity in intestinal epithelium in mice. Our findings support the potential of Proton FLASH to improve the therapeutic ratio for abdominal radiation exposure ...

Pitfalls and missing links in current understanding of 4D genomes

Quantitative Biology, Volume 14, Issue 2, June 2026.
Abstract The spatial and temporal organization of the genome—collectively termed the 4D genome—is pivotal for regulating gene expression, maintaining genome stability, and guiding development. The convergence of chromosome conformation capture technologies, super‐resolution microscopy, and single‐cell epigenomics has transformed our understanding of ...

Overview of molecular signatures of senescence and associated resources: pros and cons

FEBS Open Bio, Volume 16, Issue 5, Page 821-836, May 2026.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Characterization of the Cdc6 Homologues from the Euryarchaeon Thermoplasma acidophilum [PDF]

The Open Biochemistry Journal, 2008
Archaeal cell division cycle protein 6 (Cdc6) homologues are thought to be involved in the initiation process of DNA replication. In the present study, a biochemical characterization of the two Cdc6 proteins from the archaeon Thermoplasma acidophilum has been performed.

Phosphorylation of mammalian CDC6 by cyclin A/CDK2 regulates its subcellular localization [PDF]

, 1999
Cyclin-dependent kinases (CDKs) are essential for regulating key transitions in the cell cycle, including initiation of DNA replication, mitosis and prevention of re-replication.

A Combination of Xanthohumol and Ursolic Acid in the Diet Leads to Synergistic Inhibition of Prostate Cancer Progression

Molecular Carcinogenesis, Volume 65, Issue 4, Page 508-522, April 2026.
ABSTRACT Prostate cancer (PCa) is the second most common cancer and second leading cause of cancer death for American men. Chemoprevention by using phytochemicals offers a promising approach to improve outcomes due to their ability to act on cancer cell metabolism and growth while maintaining low toxicity profiles.

Co‐Treatment With rhBMP‐2 and Rapamycin Modulates Osteogenesis–Adipogenesis Balance to Enhance Aged Bone Regeneration

Advanced Science, Volume 13, Issue 13, 3 March 2026.
This study demonstrates that the imbalance between osteogenic and adipogenic differentiation in senescent BMSCs, leading to excessive adipocyte accumulation, which subsequently impairs bone regeneration in aged mice. To address this pathological dysregulation, a novel energy‐supplying hydrogel system (PBR) has been developed to restore balanced ...

Cdc6 ATPase activity regulates ORC center dot Cdc6 stability and the selection of specific DNA sequences as origins of DNA replication

, 2007
DNA replication, as with all macromolecular synthesis steps, is controlled in part at the level of initiation. Although the origin recognition complex ( ORC) binds to origins of DNA replication, it does not solely determine their location.

Cdc6 contributes to abrogating the G1 checkpoint under hypoxic conditions in HPV E7 expressing cells

Scientific Reports, 2017
The human papillomavirus (HPV) plays a central role in cervical carcinogenesis and its oncogene E7 is essential in this process. We showed here that E7 abrogated the G1 cell cycle checkpoint under hypoxia and analyzed key cell cycle related proteins for ...

Apolipoprotein E Deficiency Impairs Human Microglial Proliferation Accompanied by Elevated Cellular Oxidative Stress

Journal of Cellular and Molecular Medicine, Volume 30, Issue 6, March 2026.
ABSTRACT The APOE gene, which encodes Apolipoprotein E (ApoE), is the strongest genetic risk locus for Alzheimer's disease (AD). A substantial fraction of AD risk genes converges on pathways controlling lipid metabolism and immune regulation, in which microglia serve as a central integrative hub in the brain.
