Podocyte cell-cell contact
Following 7.5% SDS/PAGE, podocyte protein (20 μg) was analyzed by western blot for cyclin D 1 (ECL detection of a 1:1000 dilution of rabbit anti-cyclin D 1 antibody, Santa Cruz BioTechnology).
Cyclin D 1 is characterized as the major D-type cyclin controlling G 1 -phase progression in kidney cells, both during normal and abnormal proliferation [ 22 23 ] . To determine whether cyclin D 1 may be active in promoting G 1 → S progression in kidneys expressing HIV-1 genes, we utilized a well-characterized HIV-1 transgenic mouse model (Tg26) of HIVAN [ 11 12 13 ] . Secondary to renal expression of the HIV-1 NL4-3 Δ gag-pol proviral transgene, adolescent Tg26 transgenics develop a progressive, proliferative renal disease marked by podocyte and tubular epithelial hyperplasia that is indistinguishable both clinically and histopathologically from human HIVAN.
In contrast, cell-cell contact in wild-type and control-infected, but not HIV-1-infected podocytes, caused a severe down-regulation of cyclin D 1 transcript and protein concomitant with the up-regulation of synaptopodin, a podocyte differentiation marker [ 7 28 ] , by the end of the 14-day differentiation period.
The following results of this study suggest that HIV-1 expression leads to cyclin D 1 -mediated G 1 → S progression in infected podocytes: cyclin D 1 transcript and protein levels are markedly up-regulated, phospho-Rb (Ser780) levels are increased, cyclin D 1 protein and phospho-Rb (Ser780) levels do not decrease with podocyte cell-cell contact and differentiation, and the up-regulation of cyclin D 1 requires the expression of HIV-1 genes, particularly HIV-1 nef.
