Liver-expressed antimicrobial peptide 2 elevation contributes to age-associated cognitive decline
(American Society for Clinical Investigation, 2023-05-22)Elderly individuals frequently report cognitive decline, while various studies indicate hippocampal functional declines with advancing age. Hippocampal function is influenced by ghrelin through hippocampus-expressed growth ... -
Novel 3D Force Sensors for a Cost-Effective 3D Force Plate for Biomechanical Analysis
(MDPI, 2023-03-02)Three-dimensional force plates are important tools for biomechanics discovery and sports performance practice. However, currently, available 3D force plates lack portability and are often cost-prohibitive. To address this, ... -
Novel compound C150 inhibits pancreatic cancer through induction of ER stress and proteosome assembly
(Frontiers Media, 2022-10-05)Pancreatic cancer is a devastating disease with a dismal prognosis and poor treatment outcomes. Searching for new agents for pancreatic cancer treatment is of great significance. We previously identified a novel activity ... -
DNAJA1- and conformational mutant p53-dependent inhibition of cancer cell migration by a novel compound identified through a virtual screen
(Springer Nature, 2022-10-31)Cancers are frequently addicted to oncogenic missense mutant p53 (mutp53). DNAJA1, a member of heat shock protein 40 (HSP40), also known as J-domain proteins (JDPs), plays a crucial role in the stabilization and oncogenic ... -
Dissecting the Genetic Basis of Variation in Drosophila Sleep Using a Multiparental QTL Mapping Resource
(MDPI, 2020-03-11)There is considerable variation in sleep duration, timing and quality in human populations, and sleep dysregulation has been implicated as a risk factor for a range of health problems. Human sleep traits are known to be ... -
Repurposing Avasimibe to Inhibit Bacterial Glycosyltransferases
(MDPI, 2022-03-17)We are interested in identifying and characterizing small molecule inhibitors of bacterial virulence factors for their potential use as anti-virulence inhibitors. We identified from high-throughput screening assays a ... -
Novel Compound C150 Inhibits Pancreatic Cancer Cell Epithelial-to-Mesenchymal Transition and Tumor Growth in Mice
(Frontiers Media, 2021-12-15)Pancreatic cancer cell epithelial-to-mesenchymal transition (EMT) is an important contributor to cell invasion and tumor progression. Therefore, targeting EMT may be beneficial for pancreatic cancer treatment. The aim of ... -
Structure–activity relationship of ipglycermide binding to phosphoglycerate mutases
(Elsevier, 2021-04-01)Catalysis of human phosphoglycerate mutase is dependent on a 2,3-bisphosphoglycerate cofactor (dPGM), whereas the nonhomologous isozyme in many parasitic species is cofactor independent (iPGM). This mechanistic and ... -
Triheptanoin Mitigates Brain ATP Depletion and Mitochondrial Dysfunction in a Mouse Model of Alzheimer’s Disease
(IOS Press, 2020-10-27)Background: Brain energy failure is an early pathological event associated with synaptic dysfunction in Alzheimer’s disease (AD). Thus, mitigation or enhancement of brain energy metabolism may offer a therapeutic avenue. ... -
Potent modulation of the CepR quorum sensing receptor and virulence in a Burkholderia cepacia complex member using non-native lactone ligands
(Nature Research, 2019-09-17)The Burkholderia cepacia complex (Bcc) is a family of closely related bacterial pathogens that are the causative agent of deadly human infections. Virulence in Bcc species has been shown to be controlled by the CepI/CepR ... -
Vaccination With Mouse Dendritic Cells Loaded With an IpaD-IpaB Fusion Provides Protection Against Shigellosis
(Frontiers Media, 2019-02-08)Diarrheal diseases are a major cause of morbidity and mortality worldwide. They are most prevalent in settings with inadequate sanitation, poor hygiene and contaminated water. An important diarrheal pathogen in such settings ... -
Activity-Based Protein Profiling Reveals That Cephalosporins Selectively Active on Non-replicating Mycobacterium tuberculosis Bind Multiple Protein Families and Spare Peptidoglycan Transpeptidases
(Frontiers Media, 2020-06-23)As β-lactams are reconsidered for the treatment of tuberculosis (TB), their targets are assumed to be peptidoglycan transpeptidases, as verified by adduct formation and kinetic inhibition of Mycobacterium tuberculosis (Mtb) ... -
Astrocytes Attenuate Mitochondrial Dysfunctions in Human Dopaminergic Neurons Derived from iPSC
(Elsevier, 2018-01-27)Astrocytes, the most populous glial cell type in the brain, are critical for regulating the brain microenvironment. In various neurodegenerative diseases, astrocytes determine the progression and outcome of the neuropathological ... -
Mitochondrial Dysfunction Triggers Synaptic Deficits via Activation of p38 MAP Kinase Signaling in Differentiated Alzheimer’s Disease Trans-Mitochondrial Cybrid Cells
(IOS Press, 2017-07-03)Loss of synapse and synaptic dysfunction contribute importantly to cognitive impairment in Alzheimer’s disease (AD). Mitochondrial dysfunction and oxidative stress are early pathological features in AD-affected brain. ... -
Mitochondrial Perturbation in Alzheimer’s Disease and Diabetes
(Elsevier, 2017-02-04)Mitochondria are well-known cellular organelles that play a vital role in cellular bioenergetics, heme biosynthesis, thermogenesis, calcium homeostasis, lipid catabolism, and other metabolic activities. Given the extensive ... -
Insulin Attenuates Beta-Amyloid-Associated Insulin/Akt/EAAT Signaling Perturbations in Human Astrocytes
(Springer Verlag, 2016-08)The excitatory amino acid transporters 1 and 2 (EAAT1 and EAAT2), mostly located on astrocytes, are the main mediators for glutamate clearance in humans. Malfunctions of these transporters may lead to excessive glutamate ... -
Oxaloacetate Enhances Neuronal Cell Bioenergetic Fluxes and Infrastructure
(Wiley, 2016-03-11)We tested how the addition of oxaloacetate (OAA) to SH-SY5Y cells affected bioenergetic fluxes and infrastructure, and compared the effects of OAA to malate, pyruvate, and glucose deprivation. OAA displayed pro-glycolysis ... -
Impaired hypothalamic-pituitary-adrenal axis and its feedback regulation in serotonin transporter knockout mice
(Elsevier, 2009-04)Our previous studies have demonstrated that mice with reduced or absent serotonin transporter (SERT+/− and SERT−/− mice, respectively) are more sensitive to stress relative to their SERT normal littermates (SERT+/+ mice). ... -
Metabolism Changes During Aging in the Hippocampus and Striatum of Glud1 (Glutamate Dehydrogenase 1) Transgenic Mice
(Springer Verlag, 2014)The decline in neuronal function during aging may result from increases in extracellular glutamate (Glu), Glu-induced neurotoxicity, and altered mitochondrial metabolism. To study metabolic responses to persistently high ... -
