C323 of SR-BI is required for SR-BI-mediated HDL binding and cholesteryl ester uptake[S]

open access: yesJournal of Lipid Research, 2011
Scavenger receptor BI (SR-BI) is an HDL receptor. It binds HDL and mediates the uptake of cholesteryl ester from HDL. Early studies have pointed out that the extracellular domain of SR-BI is critical for SR-BI-mediated cholesteryl ester uptake.

Glutathione Metabolism in Renal Cell Carcinoma Progression and Implications for Therapies [PDF]

open access: yes, 2019
A significantly increased level of the reactive oxygen species (ROS) scavenger glutathione (GSH) has been identified as a hallmark of renal cell carcinoma (RCC). The proposed mechanism for increased GSH levels is to counteract damaging ROS to sustain the

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

open access: yesAging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

LDLs stimulate p38 MAPKs and wound healing through SR-BI independently of Ras and PI3 kinases⃞

open access: yesJournal of Lipid Research, 2009
Intracellular signals elicited by LDLs are likely to play a role in the pathogenesis associated with increased LDL blood levels. We have previously determined that LDL stimulation of human skin fibroblasts, used as a model system for adventitial ...

Identification of a Candidate CD5 Homologue in the Amphibian Xenopus laevis [PDF]

open access: yes, 1995
We identified a novel T cell Ag in the South African clawed toad (Xenopus laevis) by a mAb designated 2B1. This Ag is present in relatively high levels on most thymocytes, approximately 65% of splenocytes, 55% of PBL, and 65% of intestinal lymphocytes ...

Hepatitis C virus relies on lipoproteins for its life cycle [PDF]

open access: yes, 2016
Hepatitis C virus (HCV) infects over 150 million people worldwide. In most cases, HCV infection becomes chronic causing liver disease ranging from fibrosis to cirrhosis and hepatocellular carcinoma.

Aging Is a Key Driver for Adult Acute Myeloid Leukemia

open access: yesAging and Cancer, EarlyView.
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

Scavenger receptor class B type I affects cholesterol homeostasis by magnifying cholesterol flux between cells and HDL

open access: yesJournal of Lipid Research, 2001
Results from several laboratories clearly indicate that expression of scavenger receptor class B type I (SR-BI) enhances the bidirectional flux of cholesterol between cells and lipoproteins.

Scavenger Receptor Class B Type I Mediates Cell Entry of Hepatitis C Virus

open access: yesJournal of International Medical Research, 2008
This study assessed the functional role of human scavenger receptor class B type I (SR-BI) as a putative hepatitis C virus (HCV) receptor using Chinese hamster ovary (CHO) cells transfected with human SR-BI (CHO–huSR-BI). The expression of SR-BI by primary Tupaia hepatocytes (PTHs), human hepatocarcinoma cell line (HepG2) cells, untransfected CHO ...

The Scavenger Receptor Class B Type I Adaptor Protein PDZK1 Maintains Endothelial Monolayer Integrity [PDF]

open access: yesCirculation Research, 2008
Circulating levels of high-density lipoprotein (HDL) cholesterol are inversely related to the risk of cardiovascular disease, and HDL and the HDL receptor scavenger receptor class B type I (SR-BI) initiate signaling in endothelium through src that promotes endothelial NO synthase activity and cell migration.
