Does l-arginine reverse the antinatriuretic effect of cyclosporin in renal transplant patients?
These results indicate that L-arginine facilitates renal vasodilatation and natriuresis in renal transplant patients. Furthermore, the observed increase in sodium excretion could indicate that L-arginine counteracts the antinatriuretic effect of cyclosporin.
The TPA-induced PKC-α phosphorylation is suppressed and then the MMP-1 and MMP-9 expressions are also inhibited by berberine. Therefore, we suggest that berberine may be used as a candidate drug for the inhibition of metastasis of human breast cancer.
