Aging Overview

Aging gene

Gene name: SEMA4C
Aging type: Prevent
Aging characteristic:
Tissue type: --
Cell name: MDA-MB-231
Gene ID: 54910
Category: protein coding
Phenotype: Breast cancer
Experimental category: HL
PMID: 31308149
Experiment: Cell morphological analysis//SA-β-gal activity assay//Knockdown//Cell counting//Immunostaining
Description: Cell counting assays demonstrated that knockdown of SEMA4C significantly inhibited 24 MDA-MB-231 cellular growth ability. Cell immunohistochemistry also indicated that MDA-MB-231 cells expressing shSEMA4C showed a >50% reduction in proliferation rate as assessed by anti-human PCNA staining.However, in the following days, some gradually acquired a flattened and enlarged cell shape, thus implying a pro-senescent non-apoptotic state.The senescent marker of SA-β-gal increased significantly in MDA-MB-231cells transfected with either siSEMA4C or siPLEXINB2 compared with control cells.


Regulatory relationship

Regulatory pathway: P53-P21
R-AG-Pathway: --
Official symbol(s): TP53-CDKN1A
Pathway experiment: Western blot//Knockdown
Pathway description: The ratio of phospho-p21Cip1–Thr145 to total p21Cip1 increased in the MDA-MB-231 cells transfected with either siSEMA4C or siPLEXINB2,suggesting that knockdown of SEMA4C or PLEXINB2 induced activation of p53, followed by activation of p21Cip1.
