Targeting Cystine Metabolism in the Lung Cancer Environment Enhances the Efficacy of Immune Checkpoint Inhibition

Advanced Science, EarlyView.
The tumor‐associated macrophages (TAMs) in lung cancer tissues exhibit active cystine metabolism. Restricting cystine concentration in macrophages induces M1 phenotypic polarization and upregulation of PD‐L1 expression through the GSH‐NF‐κB signaling pathway.

Dual‐Crosslinked Betaine‐Based Amphiphilic Hydrogel as a Promising Vitreous Substitute: Anti‐Adhesion, Anti‐Fouling, and Anti‐Cell Proliferation

Advanced Science, EarlyView.
A novel multiple cross‐linked betaine‐type amphiphilic polymer hydrogels are developed via in situ free radical copolymerization. The resultant formation, named P(SBMA‐co‐AANa) hydrogel, functions as a vitreous substitute and demonstrates superior performance in optical properties, support capacity, and biocompatibility on a vitrectomized rabbit model.

Polyacrylamide Gel Electrophoresis

Cold Spring Harbor Protocols, 2020
Cross-linked chains of polyacrylamide can be used as electrically neutral gels to separate double-stranded DNA fragments according to size and single-stranded DNAs according to size and conformation. Polyacrylamide gels have the following three major advantages over agarose gels: (1) Their resolving power is so great that they can separate molecules of

Polyacrylamide Gel Electrophoresis

Science, 1971
Polyacrylamide gel electrophoresis (PAGE) provides a versatile, gentle, high resolution method for fractionation and physical-chemical characterization of molecules on the basis of size, conformation, and net charge. The polymerization reaction can be rigorously controlled to provide uniform gels of reproducible, measurable pore size over ...

ELECTROPHORESIS OF HISTONES ON POLYACRYLAMIDE GELS

Canadian Journal of Biochemistry and Physiology, 1963
Histories extracted from various organs of the rat have been fractionated by electrophoresis on Polyacrylamide gels. The most convenient reagents to form the gel were selected and the effects of varying concentrations of these reagents on the resolution of histones were investigated.

Native Polyacrylamide Gels

2012
Usually proteins are separated by polyacrylamide gel electrophoresis (PAGE) in the presence of a detergent and under (heat-) denaturing and (non- or) reducing conditions. The most commonly used detergent is sodium dodecyl sulfate (SDS). The major function of SDS is to shield the respective charge of the proteins present in the mixture to be analyzed ...

Diffusion in polyacrylamide gels

Polymer, 1981
Abstract Using a novel sorption technique, the diffusion of some series of solutes in polyacrylamide gels has been investigated with regard to: (a) molecular size of solute; (b) concentration of solute and gel polymer; and (c) temperature. The approach used also yields the partition coefficient pertaining to sorption equilibrium. The ratio, D D

Visualization of proelastase in polyacrylamide gels

Analytical Biochemistry, 1977
Abstract Our attempt to identify as many pancreatic enzymes as possible after their electrophoretic separation on polyacrylamide gels led us to search for a specific and simple method to localize proelastase. Esterolytic activity of elastase or elastase-like enzymes has been visualized in polyacrylamide gels (1,2) and cellulose acetate plates (3) by

Oriented macroporous polyacrylamide gels

ELECTROPHORESIS, 1997
AbstractMacroporous gels with huge cavities and partition walls result from controlled microsyneresis during gelation. In this report we show that the microsyneresis process can be further controlled: it is possible to orient the partition walls of macropores by the use of an electric field throughout polymerization.
