Profound Re-Organization of Cell Surface Proteome in Equine Retinal Pigment Epithelial Cells in Response to In Vitro Culturing [PDF]

open access: yes, 2012
The purpose of this study was to characterize the cell surface proteome of native compared to cultured equine retinal pigment epithelium (RPE) cells. The RPE plays an essential role in visual function and represents the outer blood-retinal barrier.

Restriction of Individual Branched‐Chain Amino Acids has Distinct Effects on the Development and Progression of Alzheimer's Disease in 3xTg Mice

open access: yesAdvanced Science, EarlyView.
Protein restriction (PR) slows Alzheimer's disease (AD) in mice, and other benefits of PR are due to decreased branched‐chain amino acids (BCAAs). We show that restricting any BCAA has benefits, with sex‐ and BCAA‐specific impacts on pathology, molecular signaling, and cognition.

A Testis‐Specific Aralkylamine N‐Acetyltransferase Regulates Dimorphic Sperm Function and Male Fertility in Moths

open access: yesAdvanced Science, EarlyView.
We identify a Lepidoptera‐conserved testis‐specific arylalkylamine N‐acetyltransferase (LTNAT) that governs male moth fertility via a novel mechanism. LTNAT loss disrupts eupyrene sperm mitochondrial derivatives and impairs apyrene sperm motility, offering a safe molecular target for innovative pesticides and genetic pest control.

Nelumbo nucifera leaf extracts inhibit the formation of advanced glycation end-products and mechanism revealed by Nano LC-Orbitrap-MS/MS

open access: yesJournal of Functional Foods, 2018
The inhibition of Nelumbo nucifera leaf (NNL) extract and its fractions on the formation of advanced glycation end-products (AGEs) was evaluated with different models. Changes in the conformational structure of bovine serum albumin (BSA) were analyzed by fluorescence spectrometry.

Occurrence of pharmaceutical and personal care products (PPCPs) in wastewater and receiving waters in South Africa using LC-Orbitrap™ MS

open access: yesEmerging Contaminants, 2020
There is continued interest in the occurrence and monitoring of emerging contaminants (ECs) in wastewater treatment plants (WWTPs) to assess their potential impact when released into the environment. The objective of this study was to determine the occurrence of pharmaceutical and personal care products (PPCPs) in WWTP influents and effluents and ...
