[Objective] To investigate the renal histological parameters in SD rats and beagles and to supply evidence for renal toxicological and pathological diagnosis. [Methods] Forty SD adult rats and 20 adult beagles (half males and half females) , were respectively executed at 12 weeks and 12 months old. Then, kidney tissue was fixed in 10% neutral formalin, embedded in paraffin, made into slices at 5?m and stained by HE. The larger diameter and shorter diameter of glomerulus in the renal cortex and outer stripe of rats and beagles were determined by Spot Advanced image analysis software. The differences of the above parameters appearing in different species and genders were compared. [Results] The larger diameter was about 96 ?m, and the shorter diameter 76 ?m in the renal cortex of the beagles, and the larger was about 120?m and the shorter 94 ?m in the outer stripe of the beagles. The differences of the larger and shorter diameters were insignificant between the male and female beagles, but the larger and shorter diameters in the outer stripe were longer than those in the cortex. The larger diameter and shorter diameter were about 87 ?m and 64 ?m respectively in the renal cortex of SD rats, and the larger was about 88 ?m and the shorter 64 ?m in the outer stripe of SD rats. The differences of the larger and shorter diameters were insignificant between the male and female beagles, as well as in the outer stripe and the cortex. [Conclusion] The nephron in the outer stripe is larger than that in the cortex of beagles but no difference of the nephron exists in SD rats. The nephron in beagles is larger than that in SD rats, and there is no difference in the nephron between male and female beagles and SD rats.

Purpose:
Chronic stress and related hormones are key in cancer progression. Peroxisome proliferator-activated receptor γ (PPARγ) and its agonists was reported that inducing anti-tumor effect. However, the function of PPARγ in pro-tumorigenic effects induced by chronic stress in breast cancer remains unknown. Herein, we have characterized a novel role of PPARγ and vascular endothelial growth factor (VEGF)/fibroblast growth factor 2 (FGF2) signals in breast cancer promoted by chronic stress.
Materials and Methods:
We performed experiments in vivo and in vitro and used bioinformatics data to evaluate the therapeutic potential of PPARγ in breast cancer promoted by stress.
Results:
Chronic stress significantly inhibited the PPARγ expression and promoted breast cancer in vivo. VEGF/FGF2-mediated angiogenesis increased in the chronic stress group compared to the control group. PPARγ agonist pioglitazone (PioG) injection offset the pro-tumorigenic effect of chronic stress. Moreover, specific β2-adrenergic receptor (β2R) antagonist ICI11-8551 inhibited the effect of chronic stress. In vitro, norepinephrine (NE) treatment had a similar tendency to chronic stress. The effect of NE was mediated by the β2R/adenylate cyclase signaling pathway and suppressed by PioG. PPARγ suppressed VEGF/FGF2 through reactive oxygen species inhibition. Bioinformatics data confirmed that therewas a lowPPARγ expression in breast invasive carcinoma. Lower PPARγ was associated with a significantly worse survival.
Conclusion
β2R activation induced by chronic stress and related hormones promotes growth and VEGF/FGF2-mediated angiogenesis of breast cancer by down-regulating PPARγ. Our findings hint that β receptor and PPARγ as two target molecules and the novel role for their agonists or antagonists as clinical medicine in breast cancer therapy
