Prevalence, Faunal Composition, And Vertical Distribution Of Bioluminescence In The Pelagic Gulf Of Mexico: Fishes, Crustaceans, Cephalopods And Gelatinous Megaplankton, Devynne M. Brown Dec 2023

Prevalence, Faunal Composition, And Vertical Distribution Of Bioluminescence In The Pelagic Gulf Of Mexico: Fishes, Crustaceans, Cephalopods And Gelatinous Megaplankton, Devynne M. Brown

All HCAS Student Capstones, Theses, and Dissertations

Bioluminescence is the phenomenon of light emission by living organisms. It occurs through a chemical reaction within an organism and serves various purposes. The diversity of bioluminescent capabilities and occurrence in unrelated taxa suggest that bioluminescence has evolved independently numerous times amongst taxa thriving in certain environments. One such environment is the deep ocean, where little to no sunlight penetrates the water column, specifically in the mesopelagic (200-1000 m depth) and bathypelagic (> 1000 m) zones. The mesopelagic and bathypelagic zones have been extensively sampled and well documented in the Gulf of Mexico (GoM), one of the few places globally …

Whole Genome Sequence Data Implicate Rbfox1 In Epilepsy Risk In Baboons, Mark Z. Kos, Melanie A. Carless, Lucy Blondell, Mary M. Leland, Koyle D. Knape, Harald H. H. Goring, Charles A. Szabo

Research Symposium

Background: Baboons exhibit a genetic generalized epilepsy (GGE) that resembles juvenile myoclonic epilepsy and may represent a suitable genetic model for human epilepsy. The genetic underpinnings of epilepsy were investigated in a baboon colony at the Southwest National Primate Research Center (San Antonio, TX) through the analysis of whole-genome sequence (WGS) data.

Methods: Baboon WGS data were obtained for 38 cases and 19 healthy controls from the NCBI Sequence Read Archive and, after standard QC filtering, two subsets of variants were examined: (1) 20,881 SNPs from baboon homologs of 19 candidate GGE genes; and (2) 36,169 protein-altering SNPs. Association tests …


Characterization Of Epithelial Growth Factor Transcripts Identified In Crotalus Atrox Venom, Ivan Lopez, Ying Jia Sep 2023

Characterization Of Epithelial Growth Factor Transcripts Identified In Crotalus Atrox Venom, Ivan Lopez, Ying Jia

Research Symposium

Epithelial Growth Factor (EGF) is the primary source in regeneration and stimulation of essential fibroblasts cells commonly found in epithelium. Studies have shown that snake venom components are becoming a growing factor in treating illnesses such as cancer, muscular dystrophy, chronic pain, blood pressure, blood clotting, etc. EGF in human cells contains a promising quaternary structure that can bind to snake venom metalloproteinases, proposing a means of activating biochemical responses through protein-protein interactions to regulate unwanted cellular functions. This supports promising research in achieving a greater understanding of regulation along cellular pathways through ligands, increasing the likelihood of targeting unwanted …


Influences Of Post-Fledging Protein Supplementation On Growth And Reactive Stress Response In Zebra Finches (Taeniopygia Castanotis), Gabrielle Morris, Mary Lindley Tharp May 2023

Influences Of Post-Fledging Protein Supplementation On Growth And Reactive Stress Response In Zebra Finches (Taeniopygia Castanotis), Gabrielle Morris, Mary Lindley Tharp

Honors Theses

Protein needs of non-poultry birds, like Zebra Finches (ZF) are understudied. ZFs consume proteinaceous half-ripe seeds during breeding and chicken eggs are recommended supplements for captive ZFs; but developmental needs are unclear. Eggs contain essential amino acids that impact the “stress” hormone, corticosterone (CORT). Diet and corticosterone influence avian growth and stress management. Juvenile egg-fed ZFs outgrow seed-fed birds. Juvenile egg-supplementation boosts adult male attractiveness due to cheek patch augmentation compared to seed-only birds. Across studies, timing of diet (nestling Vs. fledgling) varies, both sexes have not been included, and simultaneous measures of growth and corticosterone are lacking. We are …


Sexual Dimorphism Of Glomerular Capillary Morphology In Rats, Zackarias Coker May 2023

Sexual Dimorphism Of Glomerular Capillary Morphology In Rats, Zackarias Coker

Undergraduate Honors Theses

Chronic kidney disease (CKD) progresses faster in males than females; however, the underlying mechanisms remain poorly understood. Sex differences in glomerular capillary morphology has been hypothesized to contribute, in part, to the increased susceptibility to hypertension-induced renal injury and CKD progression in males, but this has not been investigated. The goal of the present study was to assess glomerular capillary morphology in male vs. female rats with intact kidneys and after uninephrectomy (UNX). We hypothesized that glomerular capillary radii (RCAP) and length (LCAP) would be greater in male rats.

Male (n=4) and female (n=4) with intact …


Effect Of Temperature On The Microbiome Of A Laboratory-Reared Colony Of Haemaphysalis Longicornis Ticks, Brianna L. Mitchell May 2023

Effect Of Temperature On The Microbiome Of A Laboratory-Reared Colony Of Haemaphysalis Longicornis Ticks, Brianna L. Mitchell

Undergraduate Honors Theses

Haemaphysalis longicornis ticks are invasive to the United States with potential to transmit several tick-borne pathogens that are native to the United States. Based on existing locations of H. longicornis in its native regions in Asia, as well as its invasive populations that are established in the United States, several geographic range prediction models have been produced to help understand future range expansion and distribution of this invasive tick in North America. Unfortunately, these models do not all agree and there is uncertainty associated with the potential geographic range expansion of H. longicornis ticks in North America. Climate can affect …


Effects Of Sow Vocalization And Scent On Complete Blood Cell Count During Early Weaning Period, Mason Paladino May 2023

Effects Of Sow Vocalization And Scent On Complete Blood Cell Count During Early Weaning Period, Mason Paladino

Biological Sciences Undergraduate Honors Theses

Piglets are deprived of their sows’ touch, sound, and smell after weaning which results in biological stress. The present study investigated continuing exposure of sow vocalization and scent during the early weaning period on complete blood cell count. A total of 12 litters, 8 piglets (4 male and 4 female) per litter were selected at weaning and assigned to 1 of 4 experimental treatments: control, O (olfactory group with scent and no vocal stimulation), V (non-olfactory with vocal stimulation), VO (vocal stimulation and olfactory stimulation) as a 2x2 factorial arrangement. Vocal stimulation was emulated by an audio recording of the …


Leptospira Seroprevalence In Companion Animals In Tennessee, Kellie Anne Mccreight May 2023

Leptospira Seroprevalence In Companion Animals In Tennessee, Kellie Anne Mccreight

Masters Theses

Leptospirosis is a re-emerging zoonotic disease in humans and animals. The bacteria Leptospira spp. causing this disease is maintained in the kidneys of animals such as rodents and cattle as well as in the environment. Animals harboring Leptospira spp. in the kidneys frequently shed the bacteria in their urine, contaminating the environment. Contact with contaminated soil and water may result in infection. Animals and humans may develop serious life threatening disease from Leptospira infection. Approximately 1 million new human cases and over 50,000 deaths are reported worldwide. Numerous animal species including rodents, cattle, and dogs may serve as reservoir …


Investigating Differences In Iga Antibody Response Against Aspergillus Fumigatus In Wild Type And Tlr7 Protein Deficient Mice, Courtney Folk Apr 2023

Investigating Differences In Iga Antibody Response Against Aspergillus Fumigatus In Wild Type And Tlr7 Protein Deficient Mice, Courtney Folk

Student Academic Conference

Aspergillus fumigatus is a commonly inhaled, respiratory fungal pathogen and an allergen found in flooded indoor environments, household dust, soil, and plant matter. While a competent immune system effectively clears the inhaled fungus, this same fungus poses a significant threat to weakened immune systems due to its potential to invade the lungs, bloodstream and brain tissue. The mouse genome is 99% similar to the human genome and can serve effectively model the effects of inhaled A. fumigatus (Guénet, 2005). Antibodies play a crucial role in neutralizing pathogens and in mediating an allergic response. In this study, we will investigate the …


Benthic Beasts: The Ecological Significance Of Lake Sturgeon And Blue Catfish In Eastern Appalachian Waterways, Stewart Thacker Apr 2023

Benthic Beasts: The Ecological Significance Of Lake Sturgeon And Blue Catfish In Eastern Appalachian Waterways, Stewart Thacker

Research Day

East Tennessee freshwater ecosystems comprise an abundance of an extremely diverse selection of species. This presentation examines Acipenser fulvescens and Ictalurus furcatus, two of the largest freshwater fish in the Appalachian area, which play significant ecological roles within the benthic dimension of our freshwater environments. Commonly known as “bottom-feeders,” Benthivorous species enjoy a broad range of food sources including other fish, detritus, crustaceans, and more. The extensive variety of food consumed by A. fulvescens and I. furcatus permits population control of other, denser, aquatic populations inhabiting other regions of the water column, as well as other organisms included …


Decoupling Body Shape And Mass Distribution In Birds And Their Dinosaurian Ancestors, Sophie Macaulay, Tatjana Hoehfurtner, Samuel R.R. Cross, Ryan D. Marek, John R. Hutchinson, Emma R. Schachner, Alice E. Maher, Karl T. Bates Mar 2023

School of Medicine Faculty Publications

It is accepted that non-avian theropod dinosaurs, with their long muscular tails and small forelimbs, had a centre-of-mass close to the hip, while extant birds, with their reduced tails and enlarged wings have their mass centred more cranially. Transition between these states is considered crucial to two key innovations in the avian locomotor system: crouched bipedalism and powered flight. Here we use image-based models to challenge this dichotomy. Rather than a phylogenetic distinction between ‘dinosaurian’ and ‘avian’ conditions, we find terrestrial versus volant taxa occupy distinct regions of centre-of-mass morphospace consistent with the disparate demands of terrestrial bipedalism and flight. …


Longitudinal Ultrasound Imaging And Network Modeling In Rats Reveal Sex-Dependent Suppression Of Liver Regeneration After Resection In Alcoholic Liver Disease, Benjamin K. Barnhart, Toshiki Kan, Ankita Srivastava, Corinne E. Wessner, John Waters, Manju Ambelil, John R. Eisenbrey, Jan B. Hoek, Rajanikanth Vadigepalli Mar 2023

Longitudinal Ultrasound Imaging And Network Modeling In Rats Reveal Sex-Dependent Suppression Of Liver Regeneration After Resection In Alcoholic Liver Disease, Benjamin K. Barnhart, Toshiki Kan, Ankita Srivastava, Corinne E. Wessner, John Waters, Manju Ambelil, John R. Eisenbrey, Jan B. Hoek, Rajanikanth Vadigepalli

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Liver resection is an important surgical technique in the treatment of cancers and transplantation. We used ultrasound imaging to study the dynamics of liver regeneration following two-thirds partial hepatectomy (PHx) in male and female rats fed via Lieber-deCarli liquid diet protocol of ethanol or isocaloric control or chow for 5–7 weeks. Ethanol-fed male rats did not recover liver volume to the pre-surgery levels over the course of 2 weeks after surgery. By contrast, ethanol-fed female rats as well as controls of both sexes showed normal volume recovery. Contrary to expectations, transient increases in both portal and hepatic artery blood flow …


Dpc29 Promotes Post-Initiation Mitochondrial Translation In Saccharomyces Cerevisiae, Kyle A. Hubble, Michael F. Henry Feb 2023

Dpc29 Promotes Post-Initiation Mitochondrial Translation In Saccharomyces Cerevisiae, Kyle A. Hubble, Michael F. Henry

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

Mitochondrial ribosomes synthesize essential components of the oxidative phosphorylation (OXPHOS) system in a tightly regulated process. In the yeast Saccharomyces cerevisiae, mitochondrial mRNAs require specific translational activators, which orchestrate protein synthesis by recognition of their target gene's 5'-untranslated region (UTR). Most of these yeast genes lack orthologues in mammals, and only one such gene-specific translational activator has been proposed in humans-TACO1. The mechanism by which TACO1 acts is unclear because mammalian mitochondrial mRNAs do not have significant 5'-UTRs, and therefore must promote translation by alternative mechanisms. In this study, we examined the role of the TACO1 orthologue in yeast. We …


Examining The Effect Of Varying Dilutions Of Octopamine On The Gut Microbiome Of Lab-Raised And Wild Acheta Domesticus By Brandon Nelson University Of Puget Sound Biology, Brandon Nelson Jan 2023

Examining The Effect Of Varying Dilutions Of Octopamine On The Gut Microbiome Of Lab-Raised And Wild Acheta Domesticus By Brandon Nelson University Of Puget Sound Biology, Brandon Nelson

Summer Research

For my research I am comparing the gut microbiome of lab raised A. Domesticus that are given various levels of Octopamine, a stress hormone, and comparing that to the gut microbiome of wild cricket types. Crickets are a widely used organism across the world for various experiments as both subject and feed. Knowing how the gut microbiome of these crickets is affected by various levels of stress will allow us to better take care of these crickets. This could also help us determine if there are any diseases that lab raised crickets may be susceptible to. A large part of …


Amphisbaenian Head Movement And Burrowing Forces In Damp Granular Media, Jacob Newell Jan 2023

Amphisbaenian Head Movement And Burrowing Forces In Damp Granular Media, Jacob Newell

Williams Honors College, Honors Research Projects

Damp granular media is a difficult environment to study because it is both practically complex and it lacks equations which fully describe its behavior. In this study, an oscillatory lateral head movement and its effects while penetrating damp granular media were tested using a robophysical model. This experimental research was inspired by the burrowing behavior of the clade Amphisbaenia, a group of usually limbless squamates that employ a variety of different burrowing behaviors, but it can apply to a wide range of burrowers. This research could help with both human burrowing technologies and the further investigation of animal behaviors.


Knockout Of Endospanin 1 Via Crispr In Zebrafish, Danio Rerio, Jared Kittinger Jan 2023

Knockout Of Endospanin 1 Via Crispr In Zebrafish, Danio Rerio, Jared Kittinger

Williams Honors College, Honors Research Projects

I made endospanin 1 knockout (KO) zebrafish to examine its effects on lipid and bone metabolism. Endospanin 1, or leptin receptor overlapping transcript (leprot), is a cytosolic protein linked to the protein hormone leptin that influences the trafficking of leptin receptors to the plasma membrane of cells. Genes for endospanin and tyrosinase (a pigmentation enzyme) were targeted via a microinjection of guide RNAs and CRISPR Cas9 into zebrafish embryos at 2-4 cell stages. I was able to disrupt the endospanin 1 gene (based upon the disruption of tyrosinase), but very few mutant zebrafish fully developed into adults. Only low KO …


Characterizing The Cutaneous Microbiome Of Eurycea Lucifuga As A Potential Defense Against Chytridiomycosis, Madeline Key Dec 2022

Characterizing The Cutaneous Microbiome Of Eurycea Lucifuga As A Potential Defense Against Chytridiomycosis, Madeline Key

Senior Honors Theses

Chytridiomycosis is an emerging infectious disease that is significantly reducing global amphibian populations. The disease is caused by Batrachochytrium dendrobatidis (Bd), a fungus that lethally modifies amphibian skin. Recent research has suggested that the cutaneous microbiome of individual amphibians may play a role in susceptibility to the pathogen. In this study, twelve cave salamanders (Eurycea lucifuga) were collected. Cutaneous bacteria from each salamander were isolated and identified using Sanger Sequencing. Additionally, a Bd-challenge assay was performed to determine each isolate’s antifungal activity. Results indicated many microbial isolates possessed inhibitory capabilities against Bd, which may …


A Paraventricular Thalamo-Accumbal Circuit Necessary For Behavioral Inhibition Is Dysfunctional During Opioid Use And Dependence, Kelsey M. Vollmer Sep 2022

A Paraventricular Thalamo-Accumbal Circuit Necessary For Behavioral Inhibition Is Dysfunctional During Opioid Use And Dependence, Kelsey M. Vollmer

MUSC Theses and Dissertations

Suppression of dangerous or inappropriate reward-motivated behaviors is critical for survival, whereas therapeutic or recreational opioid use can unleash detrimental behaviors and opioid use disorder (OUD). Nevertheless, the neuronal systems that suppress maladaptive motivated behaviors remain unclear, and whether opioids disengage those systems is unknown. Here, we investigate the posterior paraventricular thalamus (pPVT) as a behavioral mediator due to its strong connectivity with brain structures important for reward processing, such as the nucleus accumbens (NAc). We and others have found pPVT-NAc neuronal activity is inhibited during reward seeking, but activated when such behaviors would be inappropriate, such as during stress …


The Effects Of Prenatal Cannabis Exposure On The Basolateral Amygdala, Karen Kw Wong Aug 2022

The Effects Of Prenatal Cannabis Exposure On The Basolateral Amygdala, Karen Kw Wong

Undergraduate Student Research Internships Conference

Clinical and preclinical studies indicate prenatal cannabis exposure (PCE) pathologically affects fetal brain development and may increase vulnerability to neuropsychiatric disorders, including schizophrenia and mood/anxiety disorders. In review research from our lab suggests that fetal exposure to Δ9-THC sex-selectively impairs mesocorticolimbic (MCL) circuit function. However, there is a distinct lack of focus on PCE models on the BLA. The BLA plays a central role within the MCL where it directly interacts with the VTA, PFC and HIPP. Importantly, our model exhibits significant VTA hyperdopaminergic activity, and sex-specific alterations to PFC/HIPP glutamate firing, alongside region- and sex-specific changes in dopamine (DA), …


Rna Isolation In Duchenne Muscular Dystrophy (Dmd) Mice Models, Salem Abu Al-Burak Aug 2022

Rna Isolation In Duchenne Muscular Dystrophy (Dmd) Mice Models, Salem Abu Al-Burak

Undergraduate Student Research Internships Conference

Fibrosis is a progressive and typically irreversible disease process characterized by the excessive deposition of collagen in organs and in tissues of the musculoskeletal (MSK) system1,2. This process, which causes loss of organ and tissue function, can be initiated by micro-traumas3, an excessive and/or prolonged immune response1, the activation and proliferation of fibrosis-inducing progenitor cells4, and a pro-fibrotic extra-cellular microenvironment5. In parallel with the events that initiate fibrosis, genetic or environmental influences may cause cells and tissues to become predisposed to fibrosis development prior to initiation. This suggests that these …


How Environmental Change Will Impact Mosquito-Borne Diseases, Arsal Khan May 2022

How Environmental Change Will Impact Mosquito-Borne Diseases, Arsal Khan

Master's Projects and Capstones

Mosquitos, the most lethal species throughout human history, are the most prevalent source of vector-borne diseases and therefore a major global health burden. Mosquito-borne disease incidence is expected to shift with environmental change. These changes can be predicted using species distribution models. With the wide variety of methods used for models, consensus for improving accuracy and comparability is needed. A comparative analysis of three recent modeling approaches revealed that integrating modeling techniques compensates for trade-offs associated with a singular approach. An area that represents a critical gap in our ability to predict mosquito behavior in response to changing climate factors, …


Full- Versus Sub-Regional Quantification Of Amyloid-Beta Load On Mouse Brain Sections, Yuu Ohno, Riley Murphy, Matthew Choi, Weijun Ou, Rachita K. Sumbria May 2022

Full- Versus Sub-Regional Quantification Of Amyloid-Beta Load On Mouse Brain Sections, Yuu Ohno, Riley Murphy, Matthew Choi, Weijun Ou, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Extracellular accumulation of amyloid-beta (Aβ) plaques is one of the major pathological hallmarks of Alzheimer's disease (AD), and is the target of the only FDA-approved disease-modifying treatment for AD. Accordingly, the use of transgenic mouse models that overexpress the amyloid precursor protein and thereby accumulate cerebral Aβ plaques are widely used to model human AD in mice. Therefore, immunoassays, including enzyme-linked immunosorbent assay (ELISA) and immunostaining, commonly measure the Aβ load in brain tissues derived from AD transgenic mice. Though the methods for Aβ detection and quantification have been well established and documented, the impact of the size of the …


Cannabinoids And Retinal Fibrotic Disorders., Lucy June Sloan May 2022

Cannabinoids And Retinal Fibrotic Disorders., Lucy June Sloan

Electronic Theses and Dissertations

Retinal fibrosis is detrimental to vision. Retinal pigment epithelial (RPE) cells contribute to several retinal fibrotic diseases. Upon exposure to TGF-β, a key fibrotic cytokine, RPE cells trans-differentiate to myofibroblasts marked by the integration of α-SMA fibers into F-actin stress fibers, which confer strong contractility. Myofibroblasts produce and contract the collagen-rich fibrotic scar and disrupt retinal architecture. In this study, we investigated the in vitro effects of the putative endocannabinoid compound N-oleoyl dopamine (OLDA) on TGF-β2 induced porcine RPE cell contraction and α-SMA expression. Using an in vitro collagen matrix contraction assay, we found that OLDA inhibited TGF-β2 induced contraction …

Strong Inferences About Pain In Invertebrates Require Stronger Evidence, Edgar T. Walters Jan 2022

Strong Inferences About Pain In Invertebrates Require Stronger Evidence, Edgar T. Walters

Animal Sentience

Evidence for sentience in animals distantly related to humans is often sought in observations of behavioral and neural responses to noxious stimuli that would be painful in humans. Most proposed criteria for painful sentience in “lower” animals such as decapod crustaceans have no necessary links to the affective (“suffering”) component of pain. The best evidence for painful affect in animals is learned aversion to stimuli associated with noxious experience, and conditioned preference for contexts associated with relief from aversive consequences of noxious experience, as expressed in voluntary behavior. Such evidence is currently lacking for any invertebrate except octopus.


No Difference In Corticosterone Concentrations Between Missouri Three-Toed Box Turtles Living In An Urban And A Rural Site, Bennett A. Lamczyk, Jamie L. Palmer, Corinne P. Kozlowski, Stephen Blake, Sharon L. Deem Jan 2022

No Difference In Corticosterone Concentrations Between Missouri Three-Toed Box Turtles Living In An Urban And A Rural Site, Bennett A. Lamczyk, Jamie L. Palmer, Corinne P. Kozlowski, Stephen Blake, Sharon L. Deem

Human–Wildlife Interactions

Baseline health data for species of conservation concern are important for understanding threats to the long-term viability of populations. One indication of health is physiological stress among individuals. Corticosterone (CORT) is frequently used to quantify stress in free-living reptile populations, as high values may be associated with reduced fitness. Herein, we describe and validate methods for quantifying blood CORT levels in three-toed box turtles (Terrapene mexicana triunguis). We subsequently use this information to evaluate stress levels in 2 populations of free-living three-toed box turtles in Missouri, USA. To our knowledge, this is the first quantification of CORT levels …


Deoxyribose Phosphate Aldolase Is Required For Development Of Hematopoietic Stem Cells In The Zebrafish Embryo, Anubhav Thapaliya, Sanyam Patel, Teerth Y. Patel, Sivam J. Bhatt, Erich W. Damm Jan 2022

Deoxyribose Phosphate Aldolase Is Required For Development Of Hematopoietic Stem Cells In The Zebrafish Embryo, Anubhav Thapaliya, Sanyam Patel, Teerth Y. Patel, Sivam J. Bhatt, Erich W. Damm

Undergraduate Research Posters

Hematopoietic stem cells (HSCs) are an integral part of modern biomedical research because they are precursors to all blood cell lineages in vertebrates. Further understanding of hematopoietic development will allow for improvements in the success of therapeutic bone marrow transplantation; which is a crucial treatment in management of both malignant and non-malignant blood disorders. Although HSC transplantation is curative for many blood disorders, finding compatible donors is difficult due to a need for immunologic compatibility. Consequently, recent research efforts have been directed towards generating HSCs for the patient, from the patient themselves through the directed differentiation of induced pluripotent stem …

Arrhythmogenic Hearts In Pkd2 Mutant Mice Are Characterized By Cardiac Fibrosis, Systolic, And Diastolic Dysfunctions, Farideh Amirrad, Rajasekharreddy Pala, Kiumars Shamloo, Brian S. Muntean, Surya M. Nauli

Pharmacy Faculty Articles and Research

Autosomal dominant polycystic kidney disease (PKD) is a hereditary disorder affecting multiple organs, including the heart. PKD has been associated with many cardiac abnormalities including the arrhythmogenic remodeling in clinical evaluations. In our current study, we hypothesized that Pkd2 gene mutation results in structural and functional defects in the myocardium. The structural and functional changes of Pkd2 mutant hearts were analyzed in the myocardial-specific Pkd2 knockout (KO) mouse. We further assessed a potential role of TGF-b1 signaling in the pathology of Pkd2-KO hearts. Hearts from age-matched 6-month-old MyH6Pkd2wt/wt (control or wild-type) and MyH6 …
