Aging Overview

Aging gene

Gene name: CDK4
Aging type: Prevent
Aging characteristic:
Tissue type: Mammary Gland
Cell name: HMEC,keratinocyte
Gene ID: 1019
Category: protein coding
Phenotype: Aging
Experimental category: L
PMID: 12545164
Experiment: Growth curve assay
Description: Overexpression of Cdk4mock infection in epidermal keratinocytes and HMECs extended their lifespan to 82 and 70 PD, respectively,compared to controls (in the absence of feeder layers 13 and 16 PD.


Regulatory relationship

Target gene: P16//P53//P21
Official symbol(s): P16//P53//P21
R-AG-Target gene: Upregulation//Upregulation//Upregulation
Subcategory: Unclear
Target gene experiment: Western blot
Target gene description: The expression of p16INK4a was greatly elevated in Cdk4-overexpressing cells cultured in the absence of feeder layers.However, higher levels of p53 and upregulation of p21WAF1 was seen in cells overexpressing Cdk4 compared to uninfected controls.
