Identifying a role for Ciz1 in the DNA damage response [PDF]

, 2011
In proliferating cells, cell cycle arrest and DNA repair are induced upon detection of DNA damage. The DNA damage response (DDR) to double strand DNA breaks is mediated by phosphatidylinositol 3-kinase-like protein kinases (PIKKs), which propagate DDR ...

alpha 2-chimaerin, a Cdc42/Rac1 regulator, is selectively expressed in the rat embryonic nervous system and is involved in neuritogenesis in N1E-115 neuroblastoma cells

, 2001
Neuronal differentiation involves Rac and Cdc42 GTPases. alpha -Chimaerin, a Rac/Cdc42 regulator, occurs as alpha 1- and alternatively spliced Src homology 2 (SH2) domain-containing alpha 2-isoforms. alpha 2-chimaerin mRNA was highly expressed in the rat

Self‐Assembling Hybrid Hydrogel Reprograms the Stromal Vascular Fraction to Treat Osteoarthritis

Advanced Science, EarlyView.
This study presents a bioinspired injectable hydrogel that enhances the therapeutic potential of stem cell‐rich stromal vascular fraction for treating osteoarthritis. By reprogramming cell behavior through epigenetic modulation, the hydrogel promotes cartilage regeneration and reduces joint damage in a rat model, offering a promising new approach for ...

PRC2.1 Coordinates Peri‐Nucleolar H3K27me3‐Enriched Heterochromatin Organization and NPM1 Pentamerization to Maintain Nucleolar Integrity

Advanced Science, EarlyView.
PRC2.1(PCL2)‐coordinated H3K27me3‐enriched PNH establishes a spatial scaffold crucial for nucleolar integrity. As a crucial coordinator, PCL2 links PRC2.1 to chromatin organization and NPM1 assembly. This network‐based model reveals how chromatin modifications and nucleolar components cooperatively maintain nucleolar architecture, revealing novel ...

CDK5: Key Regulator of Apoptosis and Cell Survival

Biomedicines, 2019
The atypical cyclin-dependent kinase 5 (CDK5) is considered as a neuron-specific kinase that plays important roles in many cellular functions including cell motility and survival. The activation of CDK5 is dependent on interaction with its activator p35,

Asynchronous nuclear division cycles in multinucleated cells [PDF]

, 2006
Synchronous mitosis is common in multinucleated cells. We analyzed a unique asynchronous nuclear division cycle in a multinucleated filamentous fungus, Ashbya gossypii.

Functional Mapping of Neurodevelopmental Disease Pathways to Key Neurodevelopmental Processes Represented in the Developmental Neurotoxicity In Vitro Testing Battery

Advanced Science, EarlyView.
Human‐relevant methods are essential for modern chemical safety assessment. This study helps define the capabilities and boundaries of an in vitro testing battery for developmental neurotoxicity by exploring its biological applicability domain. By linking neurodevelopmental disease‐related pathways to key neurodevelopmental processes, the work enhances

Brachyury regulates proliferation of cancer cells via a p27Kip1-dependent pathway [PDF]

, 2014
The T-box transcription factor Brachyury is expressed in a number of tumour types and has been demonstrated to have cancer inducing properties. To date, it has been linked to cancer associated induction of epithelial to mesenchymal transition, tumour ...

Senolytic Therapy as a Preventive Strategy for Spine Degeneration and Pain

Advanced Science, EarlyView.
Cellular senescence promotes inflammation, tissue degeneration, and chronic back pain. In sparc‐null mice, early oral administration of the senolytic agents o‐vanillin and RG‐7112 reduced senescent cell burden and pro‐inflammatory SASP signaling across intervertebral discs, endplates, vertebral bone, and spinal cord.

The role of anchorage in cell cycle control

, 2009
Mammalian cells generally require both mitogens and anchorage signals in order to proliferate. Failure to receive these signals results in either cell-cycle arrest or cell death, known as anoikis, due to activation of anchorage-dependent checkpoint ...
