In contrast, LAL treatment mediated no detectable changes of p16,Cyclin D1 and E2F1 expression level. In line with this,SAL treatment led to inhibition of down-stream targets of pRB, Cyclin D1 as well as E2F1 at mRNA level, whereas the p16 mRNA is upregulated by SAL doses. Accordingly, the mRNA level of ID1, an inhibitor of p16 expression, is reduced upon SAL administration . Thus, these data indicate that the p16-pRb-E2F1 pathway is associated with the androgen-mediated cellular senescence.Src-Akt-mTOR  :Notably, treatment of LNCaP cells with the Src inhibitor PP2 under SAL conditions reduces the androgen-mediated cellular senescence. In contrast, inhibition of Src without androgens or with LAL has no detectable influence on the SA -Gal activity in LNCaP cells compared to control. Akt phosphorylation is a well-known pathway of the Src tyrosine kinase and involves signaling molecules such as the PI3K as well as the mammalian target of rapamycin (mTOR). Using inhibitors the role of these factors in androgen-mediated cellular senescence was analyzed. Inhibition of PI3K, an Akt-activating kinase,by the 3-MA inhibitor, reduced the level of androgen-induced cellular senescent cells, which confirms that the Src-Akt signaling pathway is involved in androgen-induced cellular senescence at supraphysiological levels. Similarly, using a specific Akt-kinase inhibitor(Akti) reveals a strong reduction of the SAL-mediated SA-Gal activity. A further downstream target of the Src- and the Akt-kinase is mTOR, which is involved in proliferation and cell cycle regulation processes [35]. Rapamycin alone mediates no detectable change in the level of cellular senescence. In contrast, rapamycin co-treated with SAL resulted in reduction of SA -Gal positive stained cells.The data show that rapamycin reduces the androgen-mediated SA -Gal activity and suggest that mTOR is partially involved in androgen-mediated cellular senescence. This supports the notion that the Src-Akt-mTOR signaling mediates the androgen-mediated induction of cellular senescence."	L	cellular senescence	25216853

In comparison with ethanol-treated cells, SB203580-treated cells had significantly decreased ethanol-stimulated expression of p16 (decreased by 25%, P < 0.05) but recovered Bmi1 and cyclin D2 levels (increased by 40%, P < 0.05; 125%, P < 0.05, respectively), which indicated that activation of p38MAPK/p16 pathway largely contributed to the ethanol-induced -cell senescence."

Sen_E_802	Sargahydroquinoic acid	Chemical compounds	HUVEC	--	Aging	Prevent	Western blot//SA--gal activity assay//Cell viability assay	"Short-term exposure to low doseH2O2 elevated protein expression of three senescence biomarkers, p53, p21, and p16, whose levels were suppressed by SHQA in a dose-dependentmanner.Whereas,SHQA suppressed the SA--Gal positive cell abundance at all three tested concentrations. The SA--Gal positive cell percentages were around 24%, 18% and 12% when pretreated with 0.5, 1.0, or 2.0 M SHQA, respectively. Culturing and passaging HUVECs in growth medium supplemented with 2.0 M SHQA remarkably delayed the cellular growth arrest. When cultured in normal medium supplemented with DMSO, the growth of HUVECs was arrested at 23.9 PDL (population doubling), whereas the supplementation of SHQA extended the cell growth to 26.3 PDL.The SA--Gal positive cells were significantly lower in cells supplemented with SHQA at PDL24 (24%), compared to cells cultured with DMSO at PDL23 (51%). SHQA treatment also reduced the protein expression levels of p53, p21, and p16 in senescent cells.

Meanwhile, the decreases in ac-p53, p21Cip1/WAF1, and p16Ink4a and the increases in p-Rb and cyclin D1 were observed."	SIRT1//CD38	Upregulation//Downregulation	RT-qPCR//Western blot	"Apigenin induced expression of the SIRT1 protein and mRNA in a concentration- and time-dependent manner. Subsequently, SIRT1 activity was examined and were found to increase with apigenin concentration and time. Apigenin increased NAD+ and NAD+/NADH activity in a concentrationdependent manner, while it attenuated CD38 activity. Next, we examined whether the apigenin-induced reduction in CD38 activation altered levels of SIRT1. As shown in Figs. 5D and 5E, apigenin and CD38 siRNA inhibited CD38 expression and modulated SIRT1 levels."	p53-p21Cip1/WAF1//p16Ink4a-Rb	Downregulation	Western blot	"Apigenin pre-treatment downregulated protein levels of ac-p53, p21Waf1/Cip1, and p16Ink4a and upregulated protein levels of p-Rb and cyclin D1.SIRT1 siRNA treatment decreased SIRT1 levels and the modulatory role of apigenin on ac-p53, p21Waf1/Cip1, p16Ink4a, p-Rb, and cyclin D1 was abolished."
