I. Kovalszky et al., SYNDECAN-1 GENE-EXPRESSION IN ISOLATED RAT-LIVER CELLS - (HEPATOCYTES, KUPFFER CELLS, ENDOTHELIAL AND ITO CELLS), Biochemical and biophysical research communications, 204(2), 1994, pp. 944-949
Normal liver contains mainly heparan sulfate proteoglycans. To determi
ne which liver cells are able to express syndecan-1 RNA, hepatocytes,
endothelial, Kupffer and Ito cells were isolated from normal rat liver
and kept in culture. Rat fibroblasts, monocytes and peritoneal macrop
hages were also studied. Immediately after isolation the steady state
level of syndecan messages in hepatocytes was comparable to that of th
e normal liver. The expression increased at day one and then remained
constant until day five. Ito and endothelial cells contained a low amo
unt of syndecan message. Freshly isolated Kupffer cells failed to expr
ess syndecan, but strong upregulation was found on the first day in cu
lture which gradually decreased by day 5. Syndecan transcripts were do
se and time dependently upregulated by endotoxin and gamma interferon
in Kupffer cells. Endotoxin had no effect on fibroblasts. (C) 1994 Aca
