TGF-beta was a potent inhibitor of fetal hepatocyte proliferation in culture, whereas insulin potentiated fetal hepatocyte growth above "mitogen-independent" levels.

One hundred pM TGF-beta stimulated insulin release during 0.5-24 h of incubation in the presence of 5.5 mM glucose, but not after 48 h; 1 nM TGF-beta also stimulated insulin release up to 2 h of exposure, but the effect was not seen after 6 h of exposure.

When cells were incubated with 25 mM glucose for 24 h, 100 pM TGF-beta significantly inhibited glucose-stimulated insulin release, whereas insulin release was not altered at 0 or 2.8 mM glucose.

On the contrary, forskolin- (10 microM) and tolbutamide- (40 microM) induced insulin release were not affected by TGF-beta.

TGF-beta affected neither the cell growth nor the cellular insulin content.

We have also observed that the development of renal hypertrophy in the insulin-dependent diabetic BB rat and NOD mouse is associated with increased expression of TGF-beta 1 in the kidney and that short-term administration of antibodies capable of neutralizing the activity of TGF-beta in the streptozotocin mouse model of diabetes results in attenuation of whole kidney and glomerular hypertrophy and overexpression of mRNAs encoding matrix components.

TGF-beta (500 pM) stimulated insulin secretion but did not influence islet insulin content or beta-cell mitogenesis either alone or in combination with TGF-alpha (200 pM or 20 nM).

The inflammatory response to hyperglycemia and insulin resistance could be the major factors for the increased expression of TGF-beta1.

Correction of the metabolic derangement with insulin decreased excretion of albumin and TGF-beta(1), but had no effect on kidney size and urine NC1 excretion, presumably because the observation period was too short.

Here, we define an important role of the TGF-beta pathway in regulation of insulin gene transcription and beta-cell function.

The urinary TGF-beta1 level increased by 56% followed by a 23% decrease in the normal glucose tolerance group, changes that were significant and corresponded to the changes in the plasma glucose and insulin concentrations.

Thus our results suggest that insulin contributes to increased TGF-beta1 production and possible early renal injury in prediabetic young African Americans.

Eight weeks after the induction of diabetes, renal mRNA levels of B2KR, CTGF, and TGF-beta as well as protein levels of CTGF and TGF-betaRII were measured in control (C), diabetic (D), and insulin-treated diabetic (D+I) rats.
