Protective Effect of Adrenomedullin on Rat Leydig Cells from Lipopolysaccharide-Induced Inflammation and Apoptosis via the PI3K/Akt Signaling Pathway ADM on Rat Leydig Cells from Inflammation and Apoptosis

Figure 4

Antiapoptotic effect of ADM on LPS-induced apoptosis in Leydig cells. Leydig cells were treated with ADM (100 nM) with or without LY294002 for 2 h prior to a 12-hour treatment with LPS (1 μg/mL). Cell apoptosis was assessed using TUNEL labeling and DAPI staining; DNA fragmentation was analyzed using ELISA detection (OD, optical density). Data were obtained from five independent experiments performed in triplicate and expressed as mean ± SEM.
