The Rep proteins of adeno-associated virus type 2 (AAV) are known to bind to Rep recognition sequences (RRSs) in the AAV inverted terminal repeats (ITRs), the AAV p5 promoter, and the preferred AAV integration site in human chromosome 19, called AAVS1.

We used the 16-mer core sequences of the RRSs in the AAV ITRs and AAVS1 separately as query sequences and identified 18 new RRSs in or flanking the genes coding for the following: tyrosine kinase activator protein 1 (TKA-1); colony stimulating factor-1; insulin-like growth factor binding protein 2 (IGFBP-2); histone H2B.1; basement membrane heparan sulfate proteoglycan, also known as perlecan; the AF-9 gene product, which is involved in the chromosomal translocation t (9:11)(p22:q23); the betaB subunit of the hormone known as inhibin; interleukin-2 enhancer binding factor; an endoplasmic reticulum-Golgi intermediate compartment resident protein called p63; a global transcription activator (hSNF2L); the beta-actin repair domain; a retinoic acid-inducible factor, also known as midkine; a breast tumor autoantigen; a growth-arrest- and DNA-damage-inducible protein called gadd45; the cyclin-dependent kinase inhibitor called KIP2, which inhibits several G1 cyclin-cyclin-dependent kinase complexes; and the hereditary breast and ovarian cancer gene (BRCA1).

|
The lysosomal enzyme iduronate-2-sulfatase (IDS) is expressed in pancreatic islets and is responsible for degradation of proteoglycans, such as perlecan and dermatan sulfate.
|
73 |
15149955
|
Neither insulin content nor secretory response to glucose (16.7 mM) was altered in mouse islets infected with lentiviral constructs carrying the IDS gene in sense orientation.
|
74 |
15149955
|
However, insulin content was reduced (35% vs. controls, P < 0.001) in islets infected with IDS antisense construct, while the secretory response of those islets to glucose was maintained.
|
75 |
15149955
|
Inhibition of IDS by antisense infection led to an increase in lysosomal size and a high rate of insulin granule degradation via the crinophagic route in pancreatic beta-cells.

|
We then asked whether transforming growth factor-beta1 (TGF-beta1) and/or vascular endothelial growth factor (VEGF) is implicated in the PKC-alpha-mediated changes in the basement membrane.
|
78 |
15277392
|
The hyperglycemia-induced expression of VEGF165 and its receptor VEGF receptor II (flk-1) was ameliorated in PKC-alpha(-/-) mice, whereas expression of TGF-beta1 was not affected by the lack of PKC-alpha.
|
79 |
15277392
|
The glucose-induced albuminuria seems to be mediated by PKC-alpha via downregulation of proteoglycans in the basement membrane and regulation of VEGF expression.

|
89 |
16866369
|
Islet amyloid polypeptide (IAPP), also referred to as amylin, aggregates in the islet extracellular space to form amyloid deposits in up to 95% of patients with the disease.
|
90 |
16866369
|
IAPP is stored with insulin in beta-islet cells and is processed in parallel by subtilisin-like prohormone convertases prior to secretion.
|
91 |
16866369
|
Immunohistochemical studies implicate the presence of the heparan sulfate proteoglycan (HSPG) perlecan in islet amyloid deposits, suggesting a role for HSPGs in mediating amyloid deposition in type 2 diabetes and implicating a binding domain in the N-terminus of proIAPP.

The protein kinase C (PKC)-beta isoform has been implicated to play a pivotal role in the development of diabetic kidney disease.
|
93 |
17259378
|
After 8 weeks of diabetes, the high-glucose-induced renal and glomerular hypertrophy, as well as the increased expression of extracellular matrix proteins such as collagen and fibronectin, was reduced in PKC-beta(-/-) mice.
|
94 |
17259378
|
Furthermore, the high-glucose-induced expression of the profibrotic cytokine transforming growth factor (TGF)-beta1 and connective tissue growth factor were significantly diminished in the diabetic PKC-beta(-/-) mice compared with diabetic wild-type mice, suggesting a role of the PKC-beta isoform in the regulation of renal hypertrophy.
|
95 |
17259378
|
Notably, increased urinary albumin-to-creatinine ratio persisted in the diabetic PKC-beta(-/-) mice.
|
96 |
17259378
|
The loss of the basement membrane proteoglycan perlecan and the podocyte protein nephrin in the diabetic state was not prevented in the PKC-beta(-/-) mice as previously demonstrated in the nonalbuminuric diabetic PKC-alpha(-/-) mice.
|
97 |
17259378
|
In summary, the differential effects of PKC-beta deficiency on diabetes-induced renal hypertrophy and albuminuria suggest that PKC-beta contributes to high-glucose-induced TGF-beta1 expression and renal fibrosis, whereas perlecan, as well as nephrin, expression and albuminuria is regulated by other signaling pathways.

Similarly, CERA treatment caused a dosage-dependent increase in p-Akt, nephrin, and perlecan tissue expression (all P < 0.05 versus placebo).
