Fei Yang – Bordenstein Lab
This art piece was created by an Artlab Artist-in-Residence, Fei Yang, who worked in the lab of Seth Bordenstein in 2019. The image is meant to represent the work done in the Bordenstein lab, which focuses on animal-microbe associations. The teal portion represents Wolbachia-infected fruit fly testes, and the viral particles represent viral infections of the Wolbachia themselves. Wolbachia is a bacterial genus that infects many arthropod species and is perhaps the most common parasitic microbe on the planet. The nested symbiosis is represented by multiple layers of the cell separated by semi-circular membranes.

Amy Stark – Penn Lab
Graduate student Amy Stark (Pharmacology) has been working on optimizing the growth conditions of retinal pigment epithelial cells. Although she expected to find an even monolayer of cells when she looked under the microscope, she instead found isolated cells in the shape of—of all things—Gonzo the Muppet! Although the immunocytochemistry she ran to validate the RPE cells’ identity did not show the expected tight junctions that would have indicated a monolayer, she got a kick out of seeing her cells. And just like Stark, we think it’s important to find the joy in the day-to-day of science, even when things don’t go right. View larger image.

The cover of Vestigo and the banner for this month’s newsletter was drawn by Kendra Oliver, an assistant professor of pharmacology. She depicted an AMPA receptor, a glutamine receptor in the brain and the focus of study of Teru Nakagawa. A faculty member in Molecular Physiology and Biophysics, Nakagawa’s work is highlighted in Vestigo’s first issue. Oliver’s science background and artistic talent allows her to represent scientific concepts in a visually stunning manner. View larger image.

Greg Salimando – Winder Lab
The image shown here was taken by Greg Salimando, a recent graduate from the lab of Danny Winder. It shows how mRNA transcripts for the N-methyl-d-aspartate receptor (NMDAR) subunit GluN2D prominently co-localize with transcripts for the neuropeptide corticotropin releasing factor (CRF) in the bed nucleus of the stria terminalis (BNST). This 20X image of the mouse BNST shows individual neural cells counterstained with the DAPI nuclei stain, in blue, and labeled for transcripts of both GluN2D (red) and CRF (green). Greg’s research during his time in Dr. Winder’s lab concerned whether GluN2D-NMDA receptor activity in the BNST could regulate emotional behavior. See his recent paper (NMDA receptors are an appealing therapeutic target, above) for more information. View larger image.

Kit-Yi Yam & Jose Maldonado – Simerly Lab
The image shown here is a forebrain cross section derived from a 3D reconstruction of light-sheet fluorescence images of an optically cleared mouse brain. Using a technique called iDISCO+, postdoc Kit-Yi Yam and Research Instructor Jose Maldonado (Richard Simerly lab, MPB) optically cleared a mouse brain and immunohistochemically labeled it for an axonal marker (green) and a neuronal marker (red). They then imaged the entire brain to reveal the distribution of axonal projections from a subpopulation of hypothalamic neurons involved in feeding. View larger image.

Noel Maxwell – Chazin Lab
2D NMR plot of wild-type calmodulin (black) and a mutant (E104K, red). Calmodulin is a calcium-binding messenger protein that is critical for Ca2+ signaling, and the E104K mutation causes a dysfunction in calcium binding. Although most mutations are embryonic lethal, this particular mutant was identified in a little girl who had recurrent cardiac arrests caused by arrhythmia. This NMR plot was generated by Noel Maxwell, a former research assistant in the lab of Walter Chazin (Biochemistry). View larger image.

Eric Figueroa – Denton Lab
Eric Figueroa, from the lab of Jerod Denton, studies VRAC, an ion channel that conducts Cl– and organic osmolytes out of cells to draw water out. In the lab, he exposes cells to a hypotonic solution to cause swelling, using a pipet to create a gradient. When swelling, the cell membrane detaches from the cytoskeleton, creating blebs (black arrow). View larger image.

Kristin Peterson – Rhoades Lab
Some cancers metastasize specifically to the bone, and Kristin Petersen, a graduate student in the lab of Julie Rhoades, part of Vanderbilt’s Center for Bone Biology, studies one such cancer: oral squamous cell carcinoma (OSCC). OSCC affects the cells that line the lips and the inside of the mouth and can invade the bones of the mandible. The image shows some cetuximab-resistant OSCC cells, which are more elongated and are more prone to migrating than non-cancer cells. The cells are stained in red (lipophilic dye), and their nuclei in blue (DAPI). View larger image.

Chris Hofmann – Emeson Lab
Chris Hofmann, a grad student in the lab of Ron Emeson, studies a G protein-coupled receptor (GPCR) called mGlu4. This image shows a calcium-sensing assay that’s used to indirectly measure the activity of mGlu4. Each spot on this assay turns darker or lighter depending on the level of activity of the GPCR in each spot. When measured over time, Hofmann can see the intensity of the light increase and decrease. He is currently exploring how point mutations affect mGlu4’s function. View larger image.

Romell Gletten – Schey Lab
Romell Gletten is a graduate student in the Kevin Schey lab. He studies the mechanisms that mediate the cellular trafficking of critical proteins such as the aquaporins in lens fiber cells. This includes the investigation of these mechanisms under both normal physiology and cataractogenesis, in addition to relevant modulatory post-translational modifications. Romell primarily employs biochemical techniques, including mass spectrometry-based proteomics, and molecular biological methods to address this research focus in both humans and animal models.

Alexandria Oviatt – Osheroff Lab
Alexandria Oviatt, a graduate student in the lab of Neil Osheroff, works with bacterial topoisomerases, enzymes that regulate supercoiling and that can remove knots and tangles from DNA. This image is a 2D gel that she generated after testing the ability of a Staphylococcus aureusgyrase (a type II topoisomerase that can introduce negative supercoils) to relax DNA. DNA can be electrophoresed on agarose gels to discern its supercoiling state, but positively and negatively supercoiled DNA run at similar speeds. To get around this problem, Oviatt runs her gels in two directions, which helps separate the different DNA species. This 2D gel shows a time course in which the gyrase relaxed positively supercoiled DNA (top left) before introducing negative supercoils (bottom right).

Caroline Cencer – Tyska Lab
There is more to this artwork than meets the eye: this kaleidoscopic image is actually a single immunofluorescence slide that has been rotated three times about a corner. The artist and researcher, graduate student Caroline Cencer (lab of Matt Tyska), uses enterocytes to study the maturation of the intestinal brush border. In this image, the microvilli (magenta) are coming out of the screen toward the viewer. View larger image.

Caroline Roe and Justine Sinnaeve – Ihrie and Irish Labs
This image shows a glioblastoma tumor that was frozen, sectioned, and stained with metal-tagged antibodies; 7 (out of more than 30) markers are shown in this particular visualization. This image is exemplary of a pilot project between the labs of Rebecca Ihrie and Jonathan Irish to bring imaging mass cytometry (IMC) to Vanderbilt. IMC allows researchers to identify 30-35 different markers to get a nuanced understanding of the types of cells that are present in a single sample, like with mass cytometry, except that IMC allows them to discern structural and spatial relationships between cell subsets. Caroline Roe is a program manager in the Irish lab and Justine Sinnaeve is a graduate student in the Ihrie lab. View larger image.

Nilay Taneja – Burnette Lab
Embryonic Stem Cell Colony
Shown is a colony of human embryonic stem cells showing the actin cytoskeleton (magenta), myosin motors (cyan) and DNA (yellow). Embryonic stem cells, that give rise to all tissues in the body, hold great potential in designing cell-based therapies for multiple diseases. Studying the cytoskeleton of these cells helps us understand how they respond to their mechanical environment and how that affects their ability to both retain their identity or differentiate into specific cell types. Technique used- Confocal microscopy, large image stitching.
