Deep Eutectic Systems as Novel Vehicles for Assisting Drug Transdermal Delivery.

In recent years, deep eutectic systems (DES) emerged as novel vehicles for facilitating the transdermal delivery of various drugs, including polysaccharides, proteins, insulin, vaccine, nanoparticles, and herb extracts. The objective of this study is to conduct a comprehensive review of the application of DES to transdermal drug delivery, based on previous work and the reported references. Following a brief overview, the roles of DES in TDDS, the modes of action, as well as the structure-activity relationship of DES are discussed.

FBXO6-Mediated Ubiquitination and Degradation of Ero1L Inhibits Endoplasmic Reticulum Stress-Induced Apoptosis.

Background/aims: FBXO6 is the substrate recognition component of a Skp1-Cullin1-F-box protein (SCF) ubiquitin E3 ligase complex, recognizing the chitobiose in unfolded N-glycoprotein to target glycoproteins for polyubiquitination and degradation. Although how FBXO6 recognizes glycoprotein has been fully investigated, the ubiquitination substrates of FBXO6 remain largely unknown. Previously, we have systematically identified the glycoproteins that interact with FBXO6 in an N-glycan dependent manner by LC/MS spectrum and confirmed the interaction between FBXO6 and glycosylated Ero1L, a protein disulfide oxidase in endoplasmic reticulum (ER).
