Homozygous loss of the cyclin-dependent kinase 4-inhibitor (p16) gene in human leukemias [PDF]
Abstract Recently, it has been shown that the homozygous deletion of the cyclin- dependent kinase-4 inhibitor (CDK4I;p16) gene, which is mapped to chromosome 9p21, is frequently observed in a wide spectrum of human cancers, including leukemias. Therefore, the CDK4I gene is thought to be a putative tumor-suppressor gene.

Mechanisms of MEOX1 and MEOX2 regulation of the cyclin dependent kinase inhibitors p21 and p16 in vascular endothelial cells. [PDF]
Senescence, the state of permanent cell cycle arrest, has been associated with endothelial cell dysfunction and atherosclerosis. The cyclin dependent kinase inhibitors p21(CIP1/WAF1) and p16(INK4a) govern the G(1)/S cell cycle checkpoint and are ...

Protective Effect of Multifloral Honey on Stem Cell Aging in a Dynamic Cell Culture Model [PDF]
Natural compounds, as honey-derived flavonoids and phenolic compounds, are increasingly investigated for their potential to mitigate skin aging and prevent oxidative stress-induced cellular damages.

Fermented Porcine Placenta and Its Dipeptides Modulate Cellular Senescence in Human Keratinocytes [PDF]
Skin aging is primarily driven by oxidative stress, mitochondrial dysfunction, and cell cycle dysregulation. This study investigated the anti-senescence effects of fermented porcine placenta (FPP) and its dipeptides, leucine–glycine (LG) and proline ...

P16 expression in human breast carcinoma and its relationship to clinicopathological parameters
Background: p16 is a cyclin-dependent kinase inhibitor and a cardinal regulator of the cell cycle. The relationship between p16 overexpression and poor prognosis of breast cancer has been reported in some studies.

Expression of the cyclin‐dependent kinase inhibitor p16 during the ongoing cell cycle [PDF]
It has been demonstrated that protein expression of p16, the inhibitor of cyclin‐dependent kinase 4 and 6, increases 4 fold at the G1/S transition when serum‐arrested cells are restimulated to logarithmic growth. We examined the cell cycle regulation of this cyclin‐dependent kinase inhibitor in cells separated according to their cell cycle phases by ...

Antagonistic interplay between necdin and Bmi1 controls proliferation of neural precursor cells in the embryonic mouse neocortex. [PDF]
Neural precursor cells (NPCs) in the neocortex exhibit a high proliferation capacity during early embryonic development and give rise to cortical projection neurons after maturation.

Both p16 and p21 Families of Cyclin-dependent Kinase (CDK) Inhibitors Block the Phosphorylation of Cyclin-dependent Kinases by the CDK-activating Kinase [PDF]
Phosphorylation of cyclin-dependent kinases (CDKs) by the CDK-activating kinase is required for the activation of CDK enzymes. Members of two families of CDK inhibitors, p16/p18 and p21/p27, become physically associated with and inhibit the activity of CDKs in response to a variety of growth-modulating signals.
