Traceless Regulation of Genetic Circuitry

Advanced Science, EarlyView.
Energy‐based, as opposed to molecular, control offers unprecedented improvements in key circuit parameters. This review summarizes the fundamentals of such traceless switches, categorizes them by trigger modalities, and compares and contrasts distinct advantages as well as shortcomings of each kind.

Efflux of lipid from fibroblasts to apolipoproteins: dependence on elevated levels of cellular unesterified cholesterol.

Journal of Lipid Research, 1992
Earlier work from this laboratory showed that enrichment of cells with free cholesterol enhanced the efflux of phospholipid to lipoprotein acceptors, suggesting that cellular phospholipid may contribute to high density lipoprotein (HDL) structure and the

Release of cholesterol-rich particles from the macrophage plasma membrane during movement of filopodia and lamellipodia. [PDF]

, 2019
Cultured mouse peritoneal macrophages release large numbers of ~30-nm cholesterol-rich particles. Here, we show that those particles represent fragments of the plasma membrane that are pulled away and left behind during the projection and retraction of ...

Schwann Cell Synthesized Cholesterol Orchestrates Peripheral Nerve Regeneration via Structural and IGF1‐Dependent Signaling Mechanisms

Advanced Science, EarlyView.
This study reveals that Schwann cell FDFT1‐mediated cholesterol synthesis is essential for peripheral nerve regeneration via dual roles: as a structural component for myelin and as a metabolic signal that upregulates IGF1. IGF1 promotes axonal growth through paracrine action and enhances Schwann cell differentiation/ myelination via an intrinsic IGF1R ...

Dual Functions of Dietary Rubber Seed Oil Supplementation: Enriching N‐3 Polyunsaturated Fatty Acids and Enhancing Antioxidant Capacity in Pekin Ducks

Animal Research and One Health, EarlyView.
Dietary RSO supplementation improved growth performance, simultaneously enriched n‐3 polyunsaturated fatty acids (n‐3 PUFA), and enhanced antioxidant capacity in Pekin ducks, which suggested that RSO has the potential to be a novel n‐3 PUFA source and an antioxidant for Pekin ducks to generate animal functional foods.

Apolipoprotein-mediated cellular cholesterol and phospholipid efflux depend on a functional Golgi apparatus

Journal of Lipid Research, 1996
Several studies have demonstrated that lipid-free apolipoproteins can promote cholesterol and phospholipid efflux from cells; however, the mechanisms and the role of cell-mediated pathways involved remain incompletely elucidated.

Nanostructured drug delivery systems for posterior segment eye diseases: Strategies to defy ocular barriers

BMEMat, EarlyView.
Efficient drug delivery to the posterior segment of the eye has long been a challenging issue due to the complex ocular barriers. The review focuses on the promise held by nanoplatforms for barrier penetration and the key mechanisms involved, also highlighting their advantages in achieving efficient drug delivery and superior treatment of PSEDs ...

Serum albumin acts as a shuttle to enhance cholesterol efflux from cells[S]

Journal of Lipid Research, 2013
An important mechanism contributing to cell cholesterol efflux is aqueous transfer in which cholesterol diffuses from cells into the aqueous phase and becomes incorporated into an acceptor particle.

Harnessing nanomaterials to precisely regulate the immunosuppressive tumor microenvironment for enhanced immunotherapy

BMEMat, EarlyView.
The immunosuppressive tumor microenvironment, characterized by hypoxia, redox imbalance, elevated interstitial fluid pressure, and acidity, was comprehensively elucidated. This review discussed the etiology and consequences of the characteristics of the immunosuppressive tumor microenvironment, and analyzed the recent advancements in nanomaterials for ...
