Study on relationship between expression of PKCα in glomeruli and development of nephropathy in diabetic rats     

JIA Zhong-hui  ZHANG Guo-zhong  GUO Bing  GUI Hua-zhen  WAN Chang-wu 《园艺学报》2003,19(9):1238-1241

AIM:To observe the dynamic changes of expression of PKCα, TGF-β₁ and α-SMA in glomeruli of diabetic rats induced by the alloxon and to invesitigate their roles in the diabetic nephropathy(DN).METHODS:Rats were randomly divided into four groups: normal control group (group A), diabetic group of one week (group B), diabetic group of one month (group C), diabetic group of two months (group D). Immunohistochemistry and Western blotting were used to detect the expression of PKCα, TGF-β₁ and α-SMA in renal tissue of all groups. Blood glucose, triglycerides, cholesterol, creatinine and urine protein were analysed by chemical methods. The morphological changes of renal tissue were checked through microscopy.RESULTS:The expression of PKCα and TGF-β₁ in renal tissue of diabetic groups were increased comparing with those of nomal control group(P<0.05). The mesangial cells expressed α-SMA in two months group. Chronologically the expression of PKCα, TGF-β₁ and α-SMA were positively correlative with each other and the impairment of kidney was also observed.CONCLUSIONS: During the DN process the expression of PKCα increased. PKCα raised GFR and the permeability of glomerular filtration membrane which enhanced urinary albumin excretion. PKCα also increased expression of TGF-β and therefore to induce the expression of α-SMA. The appearance of α-SMA was a marker of the phenotypic transform of renal cells.  相似文献   

Gene expression of 5α-reductase (type 2) in reproductive gland of pubertal diabetic rats     

LIU Su-huan  WANG Zhong-shan  XU Zong-ge  XIN Ji-li  ZUO Wen-jing 《园艺学报》2004,20(9):1580-1582

AIM: To study the molecular mechanism of reproduction dysfunction in pubertal diabetic rat, the level of 5α-reductase (type 2) mRNA in testis, epididymis and prostate in diabetic rat was detected. METHODS: The gene expression of 5α-reductase (type 2) was detected by Northern blot. RESULTS: In the caput of the epididymis, the expression of 5α-reductase (type 2) mRNA of D and ID groups was less than that of C group. CONCLUSION: The decreased expression of 5α-reductase (type 2) results in the decreased production of dihydrotestosterone, which influences the development and function of reproduction system in pubertal rats.  相似文献

The role of resistin in obesity and diabetes     

WANG Cheng  LI Li  WU Li-ling 《园艺学报》2004,20(10):1925-1928

Increased evidences indicate that resistin is a new hormone secreted from adipose tissue, it is reported to be an important signal molecule linking between obesity, insulin resistance and type 2 diabetes. Many factors can affect the gene expression of resistin. However, the detailed function of resistin still remains mysterious and much work needs to be undertaken.  相似文献   

Cell direct reprogramming：a new technique for treating diabetes     

REN Li-wei  YANG Xiao-fei  LI Fu-Rong 《园艺学报》2014,30(12):2284-2288

Diabetes is characterized by an absolute or relative deficiency in β-cell mass, which cannot be reversed with existing therapeutic strategies. The restoration of the endogenous islet β-cells can stabilize the level of blood glucose. The islet β-cells can be obtained from the directional differentiation of stem cells, but the process is complex and has the risk of teratomas generation. Cell direct reprogramming, one terminal differentiated cell can transdifferentiate into another kind of terminal differentiated cell, which is other than directional differentiation from stem cells. Direct reprogramming gives rise to the generation of islet β-cells from one terminal differentiated cell, may be preferable for diabetes therapy because of its unique advantage.  相似文献

Plasma leptin concentration in dogs: effects of body condition score, age, gender and breeds     

Ishioka K  Hosoya K  Kitagawa H  Shibata H  Honjoh T  Kimura K  Saito M 《Research in veterinary science》2007,82(1):11-15

Leptin is a cytokine produced by adipocytes, and plays a key role in the regulation of energy balance. In the present study, we measured plasma leptin concentrations of 166 normal and obese dogs visiting veterinary practices, and clarified the influence of age, gender and breed on plasma leptin levels in dogs. Leptin levels were higher in the dogs with higher body condition scores. There was no noticeable influence of age, gender and breed, but those in optimal puppies and obese Miniature Dachshund tended to be lower than those in corresponding groups. We conclude that plasma leptin is a reliable marker of adiposity in dogs regardless of age, gender and breed variations, and thereby useful as a blood biochemistry test for health examinations and treatment of obesity.  相似文献
