Protocol To Detect M22g Modification On Single Trna Iso-Decoders By Immuno-Northern Blotting, Sseu-Pei Hwang, Katherine Barondeau, Catherine Denicourt

Faculty, Staff and Student Publications

tRNA modifications are highly dynamic and play crucial roles in regulating gene expression. Here, we present an assay for analyzing N2, N2-dimethylguanosine (m22G) modifications on tRNAs using an antibody-based detection approach. We describe steps for isolating tRNAs from human cells via ion-exchange chromatography, capturing specific tRNA iso-decoders on streptavidin magnetic beads, and detecting modifications through immuno-northern blotting. This approach enables researchers to investigate other tRNA modifications using specific antibodies or downstream approaches such as mass spectrometry.

Memantine Inhibits Calcium-Permeable Ampa Receptors, Elisa Carrillo, Alejandra Montaño Romero, Cuauhtemoc U Gonzalez, Andreea L Turcu, Santiago Vázquez, Edward C Twomey, Vasanthi Jayaraman

Faculty, Staff and Student Publications

Memantine is an US Food and Drug Administration (FDA) approved drug that is thought to selectively inhibit NMDA-subtype of ionotropic glutamate receptors (NMDARs). NMDARs enable calcium influx into neurons and are critical for normal brain function. However, increasing evidence shows that calcium influx in neurological diseases is augmented by calcium-permeable AMPA-subtype ionotropic glutamate receptors (AMPARs). Here, we demonstrate that these calcium-permeable AMPARs (CP-AMPARs) are inhibited by memantine. Electrophysiology unveils that memantine inhibition of CP-AMPARs is dependent on their calcium permeability and the presence of their neuronal auxiliary subunit transmembrane AMPAR regulatory proteins (TARPs). Through cryo-electron microscopy we elucidate that memantine …

Enzyme-Independent Functions Of Hdac3 In The Adult Hear, Sichong Qian, Chen Zhang, Wenbo Li, Shiyang Song, Guanqiao Lin, Zixiu Cheng, Wenjun Zhou, Huiqi Yin, Yueli Wang, Haiyang Li, Ying H Shen, Zheng Sun

Center on Aging Staff Publications

The cardioprotective effects of histone deacetylase (HDAC) inhibitors (HDIs) are at odds with the deleterious effects of HDAC depletion. Here, we use HDAC3 as a prototype HDAC to address this contradiction. We show that adult-onset cardiac-specific depletion of HDAC3 in mice causes cardiac hypertrophy and contractile dysfunction on a high-fat diet (HFD), excluding developmental disruption as a major reason for the contradiction. Genetically abolishing HDAC3 enzymatic activity without affecting its protein level does not cause cardiac dysfunction on HFD. HDAC3 depletion causes robust downregulation of lipid oxidation/bioenergetic genes and upregulation of antioxidant/anti-apoptotic genes. In contrast, HDAC3 enzyme activity abolishment causes …

Faculty, Staff and Students Publications

Synthetic biology has enabled the development of biosensors to detect intestinal inflammation, yet few target the clinically validated biomarker of intestinal inflammation calprotectin with both diagnostic and therapeutic capabilities. Here, an optimized calprotectin biosensor is presented that leverages a zinc uptake regulator (Zur) controlled promoter coupled with a memory circuit to detect and record intestinal inflammation in vivo. The level of biosensor activation strongly correlates with calprotectin levels in the colon of two independent mouse models of colitis. Coupling of the biosensor with the production of the anti-inflammatory cytokine IL10 allowed for the resolution of chemically induced colitis, demonstrating the …

Effects Of Stressor Exposure And Locus Coeruleus Opioid Signaling On Coping And Anxiety-Like Behavior In Rats, John Arthur Tkaczynski

Theses and Dissertations

Stress is a physiological state of altered neuroendocrine signaling and heightened indices of behavioral vigilance and arousal in response to threatening stimuli. This project aimed to investigate the adaptations to stress that occur in the noradrenergic locus coeruleus (LC) and how these changes affect stress coping behavior. We began by investigating how adolescent restraint and predator odor stress affects coping when presented with a secondary noxious stimulus in the defensive shock probe burying task one week following stressor exposure, finding that stressed male rats demonstrate a more active coping response and stressed female rats demonstrate a more passive coping response, …

Journal of King Abdulaziz University: Medical Sciences

Background: Anemia can adversely affect cognitive development in infants and children, potentially leading to challenges in cognition, motor control, social interaction, and neurophysiological functioning. Full-term infants do not develop iron deficiency anemia within the first four months of life, as they are born with sufficient iron stores accumulated during their intrauterine life. These stores are usually adequate for four to six months of postnatal life. However, exclusive breastfeeding beyond six months without iron supplementation can increase the risk of iron deficiency anemia, as breast milk does not provide enough iron to meet the growing infant’s demand. The American Academy of …

Ifi16 Mediates Deacetylation Of Kshv Chromatin Via Interaction With Nurd And Sin3a Co-Repressor Complexes, Anandita Ghosh, Bala Chandran, Arunava Roy

School of Medicine Faculty Publications

IFI16 is a well-characterized nuclear innate immune DNA sensor that detects foreign dsDNA, including herpesviral genomes, to activate the inflammasome and interferon pathways. Beyond immune signaling, IFI16 also functions as an antiviral restriction factor, promoting the silencing of invading viral genes through transcriptional and epigenetic mechanisms. We recently demonstrated another role of IFI16, in which it interacts with and recruits the class I histone deacetylases, HDAC1 and 2, to the KSHV latency protein LANA, modulating its acetylation and function. In this study, we asked whether these IFI16-HDAC1/2 interactions contribute to broader epigenetic regulation of the KSHV chromatin. Our findings reveal …

Interferon-gamma release assays (IGRAs) that evaluate an individual’s T-cell activation response to Mycobacterium tuberculosis (M.tb)-specific peptides serve an important role in diagnosing tuberculosis (TB). However, there are substantial challenges to the use of IGRAs in resource-limited settings. Further, IGRA diagnostic performance can also be compromised in anergic individuals. Here we describe a microfluidic chip-based antigen-specific T-cell response assay (ASTRA) that automates the detection of M.tb-specific T-cell activation responses to facilitate screening for latent M.tb infection and TB. We observe that ASTRA demonstrates high specificity for M.tb infection in independent patient cohorts. Compared with IGRA, ASTRA shows greater …

Mutations in RNA splicing factors are prevalent across cancers and generate recurrently mis-spliced mRNA isoforms. Here we identified a series of bona fide neoantigens translated from highly stereotyped splicing alterations promoted by neomorphic, leukemia-associated somatic splicing machinery mutations. We utilized feature-barcoded peptide-MHC dextramers to isolate neoantigen-reactive T cell receptors (TCRs) from healthy donors, patients with active myeloid malignancy, and following curative allogeneic stem cell transplant. Neoantigen-reactive CD8+ T cells were present in the blood of patients with active cancer and had a distinct phenotype from virus-reactive T cells with evidence of impaired cytotoxic function. T cells engineered with TCRs recognizing …

Chemotype- And Target-Driven Genome Mining For A New Natural Product Inhibitor Of Bacterial Peptide Deformylase, Jonas H Costa-Martini, Eva E Adams, Chad W Johnston

Faculty, Staff and Students Publications

Antibiotics are essential for modern medicine, but their use drives the evolution of antimicrobial resistance (AMR) that limits the long-term efficacy of any one drug. To keep pace with AMR and preserve our ability to treat bacterial infections, it is essential that we identify antibiotics with new structures and targets that are not affected by clinical resistance. Historically, most developmental candidates for antibiotics have come from microbial natural products, as they feature chemical structures and biological activities that have been honed over millions of years of evolution. Unfortunately, as classical bioactivity screens for natural product discovery are blind to the …

The Carsr Two-Component System Directly Controls Radd Expression As A Global Regulator That Senses Bacterial Coaggregation In Fusobacterium Nucleatum, Bibek G C, Chenggang Wu

Faculty, Staff and Student Publications

Two-component systems (TCS) enable bacteria to sense and respond to environmental signals, facilitating rapid adaptation. Fusobacterium nucleatum, a key oral pathobiont, employs the CarSR TCS to modulate coaggregation with various gram-positive partners by regulating the expression of radD, encoding a surface adhesion protein, as revealed by RNA-Seq analysis. However, the direct regulation of the radD-containing operon (radABCD) by the response regulator CarR, the broader CarR regulon, and the signals sensed by this system remain unclear. In this study, chromatin immunoprecipitation followed by high-throughput DNA sequencing (ChIP-seq) identified approximately 161 CarR-enriched loci across the genome and …
