Research

My research focuses on investigating the function of CST6, a lysosomal protease inhibitor, in the multiple myeloma microenvironment. I focus on CST6’s immunosuppressive function in the microenvironment, as it has been shown to induce anti-inflammatory responses in macrophages. I used mainly mouse bone marrow primary cells and the KaLwRij mouse model to analyze the immunosuppressive effect of CST6. Using the co-culture assay, flow cytometry, and ELISA, I demonstrated that CST6 can further inhibit T-cell activity and induce T-cell exhaustion. Via mutagenesis, I found that a CST6 mutant, CST6^N137D, does not have an immunosuppressive effect while retaining its ability to inhibit myeloma-induced bone lesion formation. Further mouse study also showed a better therapeutic outcome of CST6^N137D on our KaLwRij model.

Notable about his time as a Graduate

I became surprisingly good at mouse tail vein injections, yet it was the task I dreaded the most during my PhD. It taught me an important lesson: “You can be excellent at something and be applauded for it, but that doesn’t necessarily mean you have to enjoy it.”

Career Goals

I am planning to transition into the industry and get a job at a biotech or pharmaceutical company. Currently, I am actively sending applications to these companies located in Boston, San Francisco, Seattle and San Diego.

Experiment or Technique you would most like to do

If there’s any chance – a systematic training on bioinformatics analysis will be nice!

Fun Facts

I like to write fantasy adventure stories. And I get cursed by my friends (also my audience), not just once, for how sad those stories end.

Research

My research centers on the apolipoprotein B mRNA editing catalytic polypeptide (APOBEC) family of nucleic acid deaminating enzymes, whose activity is the second leading known cause of mutagenesis in cancer. I study the processes by which the APOBEC family member AID (activation induced cytidine deaminase) diverges from its normal role of mutating immunoglobulin DNA to generate oncogenic mutations in lymphoma-associated genes such as BCL2 and MYC. Through this work, we now understand that G-quadruplexes (noncanonical DNA secondary structures formed by stacked guanine tetrads) in both of these genes can stimulate AID activity by a subset of APOBECs including AID. This research, along with the broader goals of the Kendrick lab, helps us understand the mechanisms by which certain lymphomas emerge and recur.

Notable about his time as a Graduate

Grad school has certainly taught me how to “fail forward,” get creative, and work with the cards that I’m dealt. I have, along with every grad student, troubleshooted countless experiments into oblivion: a practice which has really blurred the line between persistence and insanity. But this has taught me (and maybe forced me) to come at questions from new angles, and many of the discoveries I’ve made probably would not have come along if this were a smooth ride.

Career Goals

I’m not sure where yet, but I will begin a postdoctoral fellowship upon completion of my degree. I’m broadly interested in mutagenesis, repair, and genome integrity, so I’m excited to see what comes next!

Experiment or Technique you would most like to do

I have very limited experience with in vivo models. I’d really like to work with murine models, or maybe even Drosophila or C. elegans to see how these things I’m studying impact a whole organism.

Fun Facts

I play a lot of volleyball any chance I get! I played most of my life and through college and still enjoy it every chance I get, though I’ve made the transition to sand volleyball to save my knees. I also dabble in tennis and any racket sport – any excuse to get outside.

Research

My research focuses on deriving mechanisms of a relatively understudied human helicase known as DNA Helicase B, or HELB for short. HELB is a first responder to many types of DNA damage, and our lab has found that it also responds to events at replication forks during DNA replication. My project aims to define molecular mechanisms of HELB action at stalled and reversed replication forks to better understand where HELB fits into various DNA replication stress response and DNA repair pathways. Notably, loss of HELB leads to resistance to PARP inhibitor (olaparib) chemotherapy in BRCA1^-/- mouse xenograft models, and loss of HELB causes cells to become sensitive to ATR inhibitor chemotherapeutics (ceralasertib, etc.). We have found that HELB is recruited to ssDNA to aid loading and unloading of various ssDNA binding proteins to aid downstream replication stress and DNA repair processes. Hopefully my research (and the broader research within the Byrd lab) to define the role(s) and mechanism(s) of HELB can be used in the future to better predict and understand chemotherapeutic efficacy.

Notable about his time as a Graduate

During my time as a graduate student, I have enjoyed getting to do a wide variety of different techniques and day-to-day tasks. On any given day, I could be:

• growing human cell lines (my millions of “children”)
• growing bacteria (my other “children”)
• accidentally growing bacteria with my human cell lines (oops)
• writing something (and pretending to be a fiction author)
• making a poster (and pretending to be a graphic designer)
• coding something (and pretending to be a programmer)
• analyzing sequencing data (and pretending like I understand anything at all about Bayesian statistics)
• doing a western blot (for the tenth time)
• silanizing my own coverslips for DNA combing (and then never actually using them)

I have learned that, if you are indecisive about your career path, graduate school lets you do it all at once (for better or for worse)!

Career Goals

My career goal is to be a science educator and/or communicator in some capacity. I have recently accepted a job offer from Lyon College in Batesville, AR to become an Assistant Professor within their Chemistry Department! I will be teaching biochemistry, general chemistry, and starting my own independent research with students in the Fall 2025 semester. I am excited to hone my communication and teaching skills, and I am excited to help students reach their career goals by engaging with chemistry in the world around them.

Experiment or technique you would most like to do

I think it would be super fun to do two-dimensional gel electrophoresis to visualize replication fork stalling at a specific site in the genome. This relatively obscure technique produces wild looking smears and arcs of DNA that can (somehow) be interpreted to learn about DNA replication at specific genomic loci. When I first came across these kinds of gels, I always joked that the images required magic to interpret.

Fun Facts

I participate in a lot of local musical ensembles. I play clarinet/contra alto clarinet in the North Little Rock Community Band, until recently played cornet in the Natural State Brass Band, and sing in my church choir. I can also play bassoon, but I’ll have to save more money to be able to purchase one!

Research

My research focuses on the melanocortin pathway in the brain which controls appetite, energy homeostasis, and glucose homeostasis. In this pathway, I am particularly interested in the function of the melanocortin 4 receptor (MC4R), a G protein-coupled receptor, and the effects of cholesterol loss on MC4R function. Brain cholesterol is mostly synthesized from within the brain as cholesterol in the periphery cannot cross the blood-brain barrier. Studies have found that cholesterol biosynthesis is decreased in the brain of Huntington’s Disease patients and in mouse models of Type 1 and Type 2 Diabetes. Using a drug called methyl-β-cyclodextrin (MβCD) to deplete cholesterol in a neuroblastoma cell line, I have found that cholesterol depletion impairs colocalization of MC4R with a vesicle-coating protein called clathrin and induces rapid desensitization of the receptor. Our lab is working to determine the mechanism of this desensitization and possible ways to restore MC4R function in a model of deficient brain cholesterol. In addition, to define the sub-cellular location of MC4R in a more physiological model, our lab expressed exogenous hemagglutinin-tagged MC4R (HA-MC4R) in primary neurons using Adeno-associated adenovirus type 2 (AAV2). We found that HA-MC4R was located both at the center and adjacent to post-synaptic sites containing ionotropic glutamate receptors, indicating that MC4R may be positioned to control glutamatergic signaling. My future research will determine how cholesterol depletion affects MC4R traffic and signaling at these sites.

Notable about her time as a Graduate

One of the first mini-projects that I had when starting graduate school was to subclone a plasmid encoding for a fluorescently-tagged G protein, Gs, which activates adenylyl cyclase. After several failed attempts and at least three months of work, I finally subcloned a plasmid that worked. Because of those failed attempts (and good record-keeping of what worked and what didn’t), I became better at subcloning and teaching others what I had learned.

Career Goals

In whatever research capacity I am involved in after the PhD, I want to continue studying neurobiology of the brain and pathology of neurodegenerative diseases and ageing and to identify possible therapeutics for improving brain function.

Experiment or technique you would most like to do

Electrophysiology—I have never done it but would like to some day!

Research

My graduate work aims to expand current knowledge on the regulation of the double stranded break response. Specifically, I study the histone H2AX and how it interacts with downstream components of the DNA damage response. Recently, I have been working to characterize a non-canonical mechanism of 53BP1 recruitment to sites of DNA damage which we found is mediated by the H2AX C-terminal linker region.

Notable about her time as a Graduate

I have been fortunate to attend multiple scientific conferences during my graduate studies. Before the conferences, I was so nervous about presenting at the poster sessions. However, once I got started, I realized that poster sessions are a lot of fun. It’s a great way to meet other scientists that are interested in your work, get input and new ideas, and geek out. So now, I look forward to presenting at poster sessions and getting to discuss my research with new people in a relaxed setting.

Career Goals

Once I obtain my PhD I will continue to pursue a career in cancer research.

Experiment or Technique most like to do

One of my favorite techniques in the lab is cloning. Prior to and during my graduate studies, I did a lot of synthetic biology to develop plasmids for my projects. I really enjoy piecing things together or changing sequences to make something entirely new.

Education

China Pharmaceutical University, B.S. in Pharmacy (Basic Pharmacy).

Research

I have two research interests: 1) Discovery and optimization of novel inhibitors of clinically relevant targets 2) PROTAC and its applications. I have been working on multiple research projects within these research scopes.

I’m currently working on my dissertation thesis based on one of the projects, titled: Identification of Imidazo[1,2 a]pyridine pyridine derivatives as FLT3 kinase inhibitors for potential treatments of acute myeloid leukemia.

Acute myeloid leukemia (AML) is a hematologic cancer characterized by proliferative, clonal, abnormally differentiated, and occasionally poorly differentiated cells. Activating mutations in FMS-like tyrosine kinase 3 (FLT3) are the most frequent genetic alteration in AML, found in approximately 30% of newly diagnosed cases, most commonly consisting of internal tandem duplication (ITD) mutations in the juxtamembrane region. Recently, several FLT3 inhibitors have demonstrated clinical activity and three are currently approved – midostaurin, quizartinib, and gilteritinib. However, their clinical efficacies are limited in part due to the emergence of secondary clinical resistance, caused by multiple mechanism including on-target FLT3 secondary mutations – FLT3-ITD/D835Y and FLT3-ITD/F691L being the most common, as well as the off-target activation of alternative pathways including the BCR-ABL pathway. Therefore, in order to overcome drug resistance and further improve outcomes, new compounds targeting FLT3-ITD with secondary mutants are urgently needed. In my works, three compounds were identified with potent anti-leukemic effects, and may be further developed for treatment of AML.

Notable about his time as a Graduate

Throughout my Ph.D. periods, I got to know that research is never a solitary work. It requires frequent communication and close collaboration to get the work done.

Career Goals

I will seek postdoc training after my Ph.D. I have already accepted the postdoc offer at Dana-Farber Cancer Institute, Harvard Medical School, working with Dr. Jun Qi. My vision for my future career is to take on the academic path and be an independent principal investigator after the postdoc training.  

Experiment or technique you would most like to do (could be something you enjoy doing or something you have never done but would like to get the opportunity to do)

I like the design and synthesis of new compounds because there is a sense of satisfaction in creating something new.

Fun Fact about Xiuqi

I like hiking and exploring nature.

Katie is a fifth year student in the Biochemistry and Molecular Biology Ph.D program.

She attended Liberty University where she completed a Bachelor of Science degree in biology with a minor in chemistry

Research Interest

My research focus is on the conserved RNA-binding protein Musashi, the proteins it associates with, and the effect those associations have on regulating translation. Musashi is a biomarker for stem cells, regulating asymmetrical differentiation and maintaining a stem cell population. Originally studied as a translational repressor, the MacNicol lab has found that Musashi is required for the translational activation of specific transcripts. However, while Musashi uses its two N-terminal RNA-recognition motifs to bind to RNA, its C-terminus is disordered and contains no enzymatic or catalytic domains. Therefore, Musashi must require protein interactions in complexes to regulate translation, the composition of which could regulate Musashi-dependent translational effects. One of those proteins is Lsm14B. We are one of the first labs to identify Lsm14B as a translational activator, and the first group to identify the Musashi:Lsm14B interaction to be necessary to translate Mos and Cyclin B5 proteins in Xenopus oocytes to re-initiation of the cell cycle as well as translating the pituitary development-specific transcription factor Prop1. I have also discovered over 200 proteins that likely associate with Musashi independent of RNA in the mouse anterior pituitary through immunoprecipitations and mass spectrometry. My research will lay the groundwork for future investigations into the regulation of Musashi-bound RNA transcripts due to Musashi-protein interactions.

Notable about her time as a graduate student

Being a Ph.D. student is already a unique experience – a global pandemic in the middle of your Ph.D. truly makes it even more unique. The amount of personal growth I have experienced not only through the usual Ph.D. experience but also through these universally trying times has affected my approach to science and my research goals, highlighting the need for good science and excellent communication.

Her career goals

I will be expanding my research training and experience through a post-doctoral research position here at UAMS.

Experiment or technique she would most like to do

I would love to learn how to conduct bioinformatics analyses.

Fun fact about Katie

I joke that I’m preparing my retirement hobbies – I love gardening, crochet, reading, and tennis. A goal of mine is to have a library of books I’ve already read.

She has a BS in Chemistry from Southern Arkansas University

Research Interest Statement

Immune checkpoint inhibitor therapy has drastically improved outcomes in treating cancer, particularly in melanoma. However, half of melanoma patients are resistant to treatment. One mechanism used by tumor cells to evade immune attack is to down-regulate major histocompatibility complex (MHC) class I molecules, which are required for cytotoxic CD8⁺ T-cells to eliminate cancer cells. To increase immunotherapeutic efficacy, it is critical to identify how to restore MHC-I expression on cancer cells so that tumor antigens are presented. We found that resveratrol elevated MHC-I expression, thereby improving CD8⁺ T-cell killing. Through proteomic interrogation, we identified the STING pathway as a potential mechanism of action. Further studies indicated that resveratrol-mediated STING signaling induced MHC-I expression through both interferon-independent and dependent pathways. Our results have uncovered the ability of STING to induce MHC-I expression independent of interferon signaling, broadening the potential of STING activation as a tool to improve immune checkpoint blockade.

Something Notable about Time as a Graduate Student

On my desk I have two quotes, one is from Joan Didion from The Year of Magical Thinking (“Read, learn, work it up, go to the literature. Information is control) and the other is from Merlin Sheldrake from Entangled Life (“What’s astonishing is the gulf between what we expect to find and what we find when we actually look”). Over the course of my studies, I’ve learned that being a scientist is an interplay between empowering yourself to ask good questions through information and expecting that the answers could be far away from what you imagined. I’m taking Didion’s quote a bit out of context for my purposes, but I relate to it in context as well.

Career Goals

As an MD/PhD student, my immediate tasks proceeding my PhD are returning to medical school to finish my medical education and then moving on to medical residency. My goal is to match into a dermatology residency program. I would like to continue contributing to research throughout the rest of my medical training. Post-residency, I plan on seeking an academic position and splitting my time between clinic and research. I would like to focus on inflammatory skin diseases and clarify targetable pathways for treatment. Health equity is also important to me. Currently I’m reading Health Communism by Artie Vierkant and Beatrice Adler-Bolton, and it really forces me to reconcile to the negative social processes that my fields help enable. When I become a physician-scientist, using my insight on both fields and how they serve as a source of knowledge and beneficence but also of capital, I plan on being involved in work progressing social justice initiatives to reach better health for all.

Experiment or Technique You would Most Like to Do

Honestly, I’m less interested in the performance of the experiments themselves, I’m more so into developing questions and plans to answer them. So, I’d like to do whatever answers the question.
