Zachary Sanchez – Dylan Burnette lab
This month’s banner image was taken by Zachary Sanchez, a Ph.D. student in the lab of Dylan Burnette (Cell and Developmental Biology. The image shows a human induced pluripotent stem cell-derived cardiomyocyte that is stained for alpha-actinin 2, a sarcomeric protein that localizes to z-lines and z-bodies. It is color coded to indicate depth (changes in the height of the cell). Sanchez took this proof-of-concept image while exploring the use of a new technique for his lab called expansion microscopy, which involves taking fixed cells or tissues and expanding their size to about four times their normal size. It is a method designed to get around the need for less accessible super-resolution techniques such as STORM.

Skylar Cuevas – undergraduate
Happy birthday, Oswald Avery! Avery, born on October 21, 1877, was the scientist who discovered that genes and chromosomes are made out of DNA. Avery died in 1955 and was buried in the Mount Olivet Cemetery in Nashville, where Dean Larry Marnett often takes his lab to commemorate him. This medallion was created by undergraduate Skylar Cuevas to distinguish Avery’s otherwise innocuous-looking gravestone. The medallion was placed during a Basic Sciences-hosted celebration of Avery’s 144th birthday in 2021.

Jessica Biddinger – Richard Simerly lab
This image is a still from a video of the “cleared” small intestine of a mouse with certain receptors marked with fluorescent proteins as observed through a light-sheet microscope (clearing makes tissue more transparent to visible light). The video was produced by Jessica Biddinger of the Richard Simerly lab as part of a project that’s looking at how the early postnatal environment can influence the development of neural circuits that are important for controlling metabolism. The Simerly lab is interested in how viscerosensory information from the gastrointestinal tract is conveyed to the brain.

In celebration of Larry Marnett’s tenure as dean, this cover is dedicated to his work with COX-2, a human enzyme that is targeted by non-steroidal anti-inflammatory drugs. This image is based on the structure of the NSAID isoxicam when bound to COX-2, a structure that Marnett’s lab determined nearly eight years ago (2014). Water molecules mediate a crucial aspect of this interaction at amino acid residues R120 and Y385. Oxicams (including isoxicam) are the only class of NSAIDs for which water-mediated binding to COX-2 is observed. The structure, including the water molecules, is essential for explaining the structure-activity of this series of drugs. The illustration was made by Kendra Oliver (Pharmacology) and is the cover art for Issue 4 of Vestigo.

Colleen Niswender – Warren Center for Neuroscience Drug Discovery
The artwork for this banner was created by Associate Professor of Pharmacology Colleen Niswender. This is what Niswender had to say about her painting titled “Neurons I Have Known and Loved”: “I enjoy creating abstract paintings that incorporate the feeling of movement. When this painting was complete, I realized it seemed to be a subconscious coupling of my scientific life as a neuropharmacologist with the artwork I’m currently exploring using the application of acrylic paint with palette knives. I hope you enjoy it!”

Göker Arpağ – Marija Žanić lab
This image, generated by postdoc Goker Arpag of Marija Žanić’s lab, is a temporally color-coded representation of the movement of microtubule polymers on a surface coated with kinesin-1 motors. For this “gliding assay,” the kinesins — motor proteins that walk along microtubules — are attached to the surface of a coverslip via their cargo-binding domain, and microtubules are added to the flow-cell on top of the kinesins. As the immobilized kinesins bind and walk along microtubules, microtubules ‘glide’ over the coverslip. Addition of proteins that serve as barriers to kinesin-based transport disrupts microtubule gliding, resulting in the microtubules circling around a pivot point. In vitro reconstitution assays like this one allow researchers to dissect the molecular mechanisms underlying kinesin-based transport in cells.

Laura Geben – Rebecca Ihrie lab, and Serena Sweet – Richard Simerly lab
Immunolabeling-enabled three-dimensional imaging of solvent-cleared organs (iDISCO+) is a technique used to clear and immunostain organs, tissues, and even whole embryos. To obtain this image, Laura Geben (Pharmacology, Rebecca Ihrie lab) and Serena Sweet (MPB, Richard Simerly lab) used iDISCO+ to clear an embryonic mouse on day 13.5. The embryo was stained with an antibody against tropomyosin receptor kinase A (TrkA), a marker of the developing nervous system. After clearing, the embryo was then imaged on a light sheet microscope at the newly established Neurovisualization Lab.

Robert Lavieri – VICTR
To cap the year, we’re featuring art by VICTR Senior Project Manager Robert Lavieri. He uses a program called UCSF Chimera to render images from coordinates in the Protein Data Bank. He then takes that “raw” image and modifies it in Photoshop to create art like this piece. Here, Lavieri worked with 5DE5, the complex between the RGG motif of the human Fragile X mental retardation protein and G-quadruplex RNA. FMRP is a regulatory RNA binding protein that plays a central role in the development of several human disorders including Fragile X Syndrome and autism. In this image, you can see both the protein — a yellow ribbon — and a stretch of bound RNA — in rainbow colors. The red spheres are potassium cations.

Fei Yang – Seth 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 – John 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.

Greg Salimando – Danny 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.

Alexandria Oviatt – Neil 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).
