The Project Symphony team publishes another research paper of 2022 in peer-reviewed Membrane Biology journal

Sunghee Lee • September 2, 2022

The Project Symphony is very proud to publish another peer-reviewed research article! It is the joyful product of our hard work and time spent in the laboratory over Summer 2021. The journal article is titled "Resveratrol decreases membrane water permeability: a study of cholesterol-dependent interactions", in The Journal of Membrane Biology, a Springer Publication.


This paper is coauthored by seven undergraduates, Jasmin Ceja-Vega ('23 Biochemistry), Escarlin Perez ('22 Biochemistry), Patrick Scollan (’21 Chemistry), Juan Rosario (’21 Chemistry), Alondra Gamez Hernandez ('23 Biochemistry), Katherine Ivanchenko (’23 Chemistry), Jamie Gudyka ('24 Biochemistry), under the mentorship of Dr. Sunghee Lee.


Resveratrol (RSV) is a biologically active plant phenol and is found in many foods, including grapes and red wine. It has been suggested that RSV has a broad range of beneficial pharmacological activities for potential therapeutic applications, as an antioxidant and anticarcinogenic agent. This study examines interactions of RSV with model membranes having varying concentrations of cholesterol (Chol), mimicking normal and cancerous cells. The perturbation of the model membrane by RSV is sensed by changes in water permeability parameters, using Droplet Interface Bilayer (DIB) models, thermotropic properties from Differential Scanning Calorimetry, and structural properties from confocal Raman spectroscopy. The nature and extent of interactions greatly depend on the presence and absence of Chol as well as the concentration of RSV. Combined results from these investigations highlight a differential effect of RSV on Chol-free and Chol-enriched membranes. These results provide increased understanding and effective use of resveratrol in disease therapy including cancer. 


Congratulations to the project team!

We’re pleased to announce our new collaborative publication, “Study of the Interaction Between Graphene Oxide and Cholesterol Using Different Artificial Membrane Models,” conducted in partnership with colleagues in Italy. This work investigates how graphene oxide—an emerging nanomaterial with biomedical promise—interacts with cholesterol within lipid membranes. By employing various artificial membrane systems, we examined how membrane composition and organization influence these interactions, revealing key insights into the physicochemical mechanisms at play. Our results contribute to a deeper understanding of how nanomaterials engage with biological membranes, providing valuable guidance for the safe and effective design of graphene-based biomedical applications. Congratulations to all team members and our Italian collaborators on this exciting achievement!

In this study, we explored how the membrane environment shapes the behavior of serotonin, a key neurotransmitter involved in mood regulation and neural signaling. By systematically varying lipid composition in model membranes, we uncovered how differences in lipid charge, fluidity, and packing influence serotonin’s nonspecific interactions with bilayers. Our findings shed new light on the physical chemistry of neurotransmitter–membrane interactions, with potential implications for understanding serotonin’s diverse physiological functions and its role in receptor signaling.

Our research team has uncovered new details about how small oil-like molecules influence the thickness and flexibility of cell membranes. These membranes, built from layers of lipids, contain tiny pockets of free space that help control how soft, dense, or permeable the membrane is. Our research team found that some smaller molecules can fit into these layers, making the membrane thicker, while larger or crystallizing ones get pushed out, leading to thinning. These changes help explain how different molecules inside a membrane affect its overall structure and function. This study not only expands our understanding of how biological membranes work but also points to new possibilities for creating custom-designed synthetic membranes for research and technology.
