False positive glycopeptide identification via in-FAIMS fragmentation

V. Rangel-Angarita, K. E. Mahoney, C. Kwon, R. Sarker, T. M. Lucas, S. A. Malaker

This study identifies a phenomenon called 'in FAIMS fragmentation' that increases spectral matches in glycopeptide analysis, highlighting potential benefits and limitations of FAIMS for O-glycoproteomics.

Air-Liquid-Interface Reorganizes Membrane Lipid and Enhance Recruitment of Slc26a3 to Lipid-Rich Domains in Human Colon

C. M. Tse, Y. Rong, Z. Zhang, R. Lin, R. Sarker, M. Donowitz, V. Singh

The paper shows that air-liquid interface culture increases DRA expression and activity in Caco-2/BBe cells and colonoids by enhancing ceramide-rich platform formation and differentiation.

SLC26A3 (DRA) is stimulated in a synergistic, intracellular Ca2+ dependent manner by cAMP AND ATP in intestinal epithelial cells

R. Sarker, R.-X. Lin, V. Singh, M. Donowitz, C. M. Tse

The paper shows that forskolin and ATP synergistically increase DRA activity in intestinal epithelial cells through intracellular Ca2+ elevation, which is blocked by BAPTA-AM.
