It has previously demonstrated that cholesterol efflux from the cell plasma membrane is increased in a mouse model of cystic fibrosis (CF) compared to a wild-type control. A noninvasive means of characterizing plasma membrane cholesterol efflux at the surface of airway tissue of CF patients is needed to extend the trends found in animal models of CF to the human disease state. Microelectrode-induced cholesterol efflux from the plasma membrane of cells at the surface of tissue is proposed as a strategy to demonstrate increased cholesterol efflux for CF in human subjects. Data demonstrating detection of cholesterol efflux from the human buccal mucosa is reported as proof-of-concept for an diagnostic assay.

C1orf115 has been identified in high-throughput screens as a regulator of multidrug resistance possibly mediated through an interaction with ATP-dependent membrane transporter ABCB1. Here we show that C1orf115 not only shares structural similarities with FACI/C11orf86 to interact with clathrin adaptors to undergo endocytosis, but also induces ABCA1 transcription to promote cholesterol efflux. C1orf115 consists of an N-terminal intrinsically disordered region and a C-terminal α-helix.

Background: Pine (Pinus koraiensis) nut oil (PNO) has been reported to have various beneficial effects on hepatic triglyceride accumulation and atherosclerosis in animal models. MicroRNAs (miRs) are involved in various diseases by modulating physiological processes. However, the mechanism underlying PNO's effects on the regulation of miRs involved in hepatic cholesterol homeostasis and inflammation remains unclear.

The breast cancer resistance protein (BCRP/ABCG2) plays a major role in the multidrug resistance of cancers toward chemotherapeutic treatments. It was demonstrated that cholesterol regulates the ABCG2 activity, suggesting that lower levels of membrane cholesterol decrease the ABCG2 activity in mammalian cells. However, the precise mechanism remains unclear.

Patellar dysplasia (PD) can cause patellar dislocation and subsequent osteoarthritis (OA) development. Herein, a novel ABCA6 mutation contributing to a four-generation family with familiar patellar dysplasia (FPD) is identified. In this study, whole exome sequencing (WES) and genetic linkage analysis across a four-generation lineage presenting with six cases of FPD are conducted.
