The cellular and molecular mechanisms responsible for lipoprotein [a] (Lp[a]) catabolism are unknown. We examined the plasma clearance of Lp[a] and LDL in mice using lipoproteins isolated from human plasma coupled to radiolabeled tyramine cellobiose. Lipoproteins were injected into wild-type, LDL receptor-deficient (Ldlr-/-), and apolipoprotein E-deficient (Apoe-/-) mice. The fractional catabol...

I N T R O D U C T I O N Chloride channels are present in the plasma membranes o f epithelia (Frizzell et al., 1981), nerve (Hamill et al., 1983), and muscle (Blatz and Magleby, 1985), as well as in intraceilular membranes such as Golgi apparatus (Glickman et al., Address reprint requests to Dr. Qais AI-Awqati, Depts. of Medicine and Physiology, College of Physicians and Surgeons, Columbia Unive...

Lipoprotein glomerulopathy is a rare kidney disease in which lipoprotein thrombi are seen in the glomerular capillaries. Most of these patients are found in Japan and East Asian countries. The presenting symptoms include proteinuria, an abnormal plasma lipoprotein profile that resembles type III hyperlipoproteinaemia, and a marked increase in serum apolipoprotein E concentration. Previous studi...

Probucol was given to rats made diabetic by streptozotocin. Compared with diabetic rats not receiving probucol or with nondiabetic rats, probucol lowered the plasma concentrations of triglycerides, phospholipids, cholesterol, and apolipoprotein B. The concentrations of serum chylomicrons and very low density lipoprotein (VLDL) were also reduced. In control and diabetic rats, probucol enhanced t...

Fresh plasma from control (C) and hyperchotesterolemlc (HC) cynomolgus monkeys was analyzed by agarose electrophoresls-lmmunoblotting with antibody to cynomolgus monkey apolipoprotein (apo) A-l. Two bands were evident on the autoradiogram: an a-migrating band (high density llpoproteln) and a /3-mlgrating band that comlgrated exactly with cynomolgus monkey low density llpoproteln (LDL). The pres...

Background & aim:  This study aimed to determine the relationship between lipid and apolipoprotein B-100 (apo B-100) levels in maternal and umbilical cord sera as well as the effects of these components on anthropometric measurements of newborn infants. Methods:This correlational study was performed on 85 appropriate for gestational age (AGA) newborns and their mothers. For analysis, 5 ml of m...
