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 ...

DNA replication licensing factor Cdc6 and Plk4 kinase antagonistically regulate centrosome duplication via Sas-6

Nature Communications, 2017
Centrosome duplication is synchronized with cell cycle events but how this is regulated at a molecular level is unclear. Here, the authors show that the DNA replication licensing factor Cdc6 restrains centrosome duplication via binding and inhibiting Sas-

A yeast GSK-3 kinase Mck1 promotes Cdc6 degradation to inhibit DNA re-replication.

PLoS Genetics, 2012
Cdc6p is an essential component of the pre-replicative complex (pre-RC), which binds to DNA replication origins to promote initiation of DNA replication. Only once per cell cycle does DNA replication take place.

Sparstolonin B inhibits pro-angiogenic functions and blocks cell cycle progression in endothelial cells. [PDF]

PLoS ONE, 2013
Sparstolonin B (SsnB) is a novel bioactive compound isolated from Sparganium stoloniferum, an herb historically used in Traditional Chinese Medicine as an anti-tumor agent. Angiogenesis, the process of new capillary formation from existing blood vessels,

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.

Two subunits of human ORC are dispensable for DNA replication and proliferation

eLife, 2016
The six-subunit Origin Recognition Complex (ORC) is believed to be an essential eukaryotic ATPase that binds to origins of replication as a ring-shaped heterohexamer to load MCM2-7 and initiate DNA replication. We have discovered that human cell lines in

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 ...

Yeast heterochromatin regulators Sir2 and Sir3 act directly at euchromatic DNA replication origins.

PLoS Genetics, 2018
Most active DNA replication origins are found within euchromatin, while origins within heterochromatin are often inactive or inhibited. In yeast, origin activity within heterochromatin is negatively controlled by the histone H4K16 deacetylase, Sir2, and ...

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.

Cdc6 and Cyclin E2 Are PTEN-Regulated Genes Associated with Human Prostate Cancer Metastasis

Neoplasia: An International Journal for Oncology Research, 2009
Phosphatase and tensin homolog deleted on chromosome 10 (PTEN) is frequently inactivated in metastatic prostate cancer, yet the molecular consequences of this and their association with the metastatic phenotype are incompletely understood.
