We evaluated the ability of the canine in situ left lower lobe (LLL) vasculature to sieve endogenous plasma proteins of various molecular radii (34-124 A) after LLL arterial pressure had been transiently elevated to 23.8 +/- 0.9 (control group, n =…
Cholesterol 7 alpha-hydroxylase catalyzes the first and rate-limiting step in the conversion of cholesterol to bile acids in the liver. Previously, we have identified two bile acid response elements located in nt -74 to -54 (BARE-I) and -148 to -118…
We have recently cloned a full-length cDNA encoding the rat hepatic cholesterol 7 alpha-hydroxylase cytochrome P450 (P450c7) (Li, Y. C., Wang, D. P., and Chiang, J. Y. L. (1990) J. Biol. Chem. 265, 12012-12019), which catalyzes the rate-limiting…
Penetration of the KOS strain of herpes simplex virus type 1 (HSV-1) and the MS and 333 strains of herpes simplex virus type 2 (HSV-2) into HEp-2 cells at pH 6.3 was at least 100-fold less efficient than at pH 7.4. Penetration of two low passage…
The cholesterol 7alpha-hydroxylase gene (CYP7A) is transcriptionally regulated by a number of factors, including hormones, bile acids, and diurnal rhythm. Previous studies have identified a region from nucleotides (nt) -74 to -55 of the rat CYP7A…
