Aging Overview

Aging gene

Gene name: ERBB2
Aging type: Prevent
Aging characteristic:
Tissue type: Prostate
Cell name: --
Gene ID: 2064
Category: protein coding
Phenotype: Prostate cancer
Experimental category: HL
PMID: 21930937
Experiment: Ki67 staining//BrdU assay//SA-β-gal activity assay
Description: The PB-Cre4: Ptenfl/fl Her2KI tumors had significantly higher levels of proliferation than the PBCre4: Ptenfl/fl tumors, as assessed by Ki67 and BrdU . Furthermore, there was a marked down-regulation of the growth arrest and senescence markers p16 and p21 in the PB-Cre4: Ptenfl/fl Her2KI compared with the PB-Cre4: Ptenfl/fl mice. Moreover, there was a robust down-regulation of senescence-associated β-galactosidase signals in the PBCre4: Ptenfl/fl Her2KI prostates compared with PB-Cre4: Ptenfl/fl mice .


Regulatory relationship

Regulatory pathway: MEK-ERK//PI3K-AKT
R-AG-Pathway: Activation//--
Official symbol(s): MAP2K7-MAPK1//
Pathway experiment: Western blot
Pathway description: Tumors from PB-Cre4: Ptenfl/fl Her2KI mice showed elevated pERK1/2 activation (with total ERK1/2 levels unchanged), whereas PB-Cre4: Ptenfl/fl tumors had very low levels of pERK1/2. Heregulin treatment also increased PTEN phosphorylation, which can in turn decrease the ability of PTEN to inhibit PI3K-mediated AKT activation .
