Abstract
Parkinson's disease (PD) is a debilitating neurodegenerative disease affecting millions of individuals worldwide. Hallmark features of PD pathology are the formation of Lewy bodies in neuromelanin-containing dopaminergic (DAergic) neurons of the substantia nigra pars compacta (SNpc), and the subsequent irreversible death of these neurons. Although genetic risk factors have been identified, around 90 % of PD cases are sporadic and likely caused by environmental exposures and gene-environment interaction. Mechanistic studies have identified a variety of chemical PD risk factors. PD neuropathology occurs throughout the brain and peripheral nervous system, but it is the loss of DAergic neurons in the SNpc that produce many of the cardinal motor symptoms. Toxicology studies have found specifically the DAergic neuron population of the SNpc exhibit heightened sensitivity to highly variable chemical insults (both in terms of chemical structure and mechanism of neurotoxic action). Thus, it has become clear that the inherent neurobiology of nigral DAergic neurons likely underlies much of this neurotoxic response to broad insults. This review focuses on inherent neurobiology of nigral DAergic neurons and how such neurobiology impacts the primary mechanism of neurotoxicity. While interactions with a variety of other cell types are important in disease pathogenesis, understanding how inherent DAergic biology contributes to selective sensitivity and primary mechanisms of neurotoxicity is critical to advancing the field. Specifically, key biological features of DAergic neurons that increase neurotoxicant susceptibility.

Abstract
Monoamine oxidase (MAO) is rapidly gaining appreciation for its pathophysiologic role in cardiac injury and failure. Oxidative deamination of norepinephrine by MAO generates H2O2 and the catecholaldehyde 3,4-dihydroxyphenylglycolaldehyde (DOPEGAL), the latter of which is a highly potent and reactive electrophile that has been linked to cardiotoxicity. However, many questions remain as to whether catecholaldehydes regulate basic physiological processes in the myocardium and the pathways involved. Here, we examined the role of MAO-derived oxidative metabolites in mediating the activation of cardiac fibroblasts in response to norepinephrine. In neonatal murine cardiac fibroblasts, norepinephrine increased reactive oxygen species (ROS), accumulation of catechol-modified protein adducts, expression and secretion of collagens I/III, and other markers of profibrotic activation including STAT3 phosphorylation. These effects were attenuated with MAO inhibitors, the aldehyde-scavenging dipeptide l-carnosine, and FPS-ZM1, an antagonist for the receptor for advanced glycation endproducts (RAGE). Interestingly, treatment of cardiac fibroblasts with a low dose (1 μM) of DOPEGAL-modified albumin phenocopied many of the effects of norepinephrine and also induced an increase in RAGE expression. Higher doses (>10 μM) of DOPEGAL-modified albumin were determined to be toxic to cardiac fibroblasts in a RAGE-dependent manner, which was mitigated by l-carnosine. Collectively, these findings suggest that norepinephrine may influence extracellular matrix remodeling via an adrenergic-independent redox pathway in cardiac fibroblasts involving the MAO-mediated generation of ROS, catecholaldehydes, and RAGE. Furthermore, since elevations in the catecholaminergic tone and oxidative stress in heart disease are linked with cardiac fibrosis, this study illustrates novel drug targets that could potentially mitigate this serious disorder.

Abstract
![]()
Monoamine oxidase
(MAO) catalyzes the oxidative deamination of
dopamine and norepinephrine to produce 3,4-dihydroxyphenylacetaldehyde
(DOPAL) and 3,4-dihydroxyphenylglycolaldehyde (DOPEGAL), respectively.
Both of these aldehydes are potently cytotoxic and have been implicated
in pathogenesis of neurodegenerative and cardiometabolic disorders.
Previous work has demonstrated that both the catechol and aldehyde
moieties of DOPAL are reactive and cytotoxic via their propensity
to cause macromolecular cross-linking. With certain amines, DOPAL
likely reacts via a Schiff base before oxidative activation of the
catechol and rearrangement to a stable indole product. Our current
work expands on this reactivity and includes the less-studied DOPEGAL.
Although we confirmed that antioxidants mediated DOPAL’s reactivity
with carnosine and N-acetyl-l-lysine, antioxidants
had no effect on reactivity with l-cysteine. Therefore, we
propose a non-oxidative mechanism where, following Schiff base formation,
the thiol of l-cysteine reacts to form a thiazolidine. Similarly,
we demonstrate that DOPEGAL forms a putative thiazolidine conjugate
with l-cysteine. We identified and characterized both l-cysteine conjugates via HPLC-MS and additionally identified
a DOPEGAL adduct with carnosine, which is likely an Amadori product.
Furthermore, we were able to demonstrate that these conjugates are
produced in biological systems via MAO after treatment of the cell
lysate with norepinephrine or dopamine along with the corresponding
nucleophiles (i.e., l-cysteine and carnosine). As it has
been established that metabolic and oxidative stress leads to increased
MAO activity and accumulation of DOPAL and DOPEGAL, it is conceivable
that conjugation of these aldehydes to carnosine or l-cysteine
is a newly identified detoxification pathway. Furthermore, the ability
to characterize these adducts via analytical techniques reveals their
potential for use as biomarkers of dopamine or norepinephrine metabolic
disruption.

Abstract
Parkinson's disease is characterized by dopamine dyshomeostasis and oxidative stress. The aldehyde metabolite of dopamine, 3,4-dihydroxyphenylacetaldehyde (DOPAL), has been reported to be cytotoxic and capable of protein modification. Protein modification by DOPAL has been implicated in the pathogenesis of Parkinson's disease, but the complete pathology is unknown. Our findings show that DOPAL modifies glutathione S-transferase (GST), an important enzyme in the antioxidant defense system. DOPAL, dopamine, and the metabolite 3,4-dihydroxyphenylacetic acid (DOPAC), inhibited the activity of GST isolated from N27 dopaminergic cells at an IC50 of 31.46 μM, 82.32 μM, and 260.0 μM, respectively. DOPAL, dopamine, and DOPAC inhibited commercially available equine liver GST at an IC50 of 23.72 μM, 32.17 μM, and 73.70 μM, respectively. This inhibition was time dependent and irreversible. 1 mM ʟ-cysteine or glutathione fully protected GST activity from DOPAL, DA, and DOPAC inhibition. 1 mM carnosine partially protected GST activity from DA inhibition. Furthermore, ʟ-cysteine was found to protect GST by forming a putative thiazolidine conjugate with DOPAL. We conclude that GST inactivation may be a part of the broader etiopathology of Parkinson's disease.

Abstract
Epigenetic modifications, including those on DNA and histones, have been shown to regulate cellular metabolism by controlling expression of enzymes involved in the corresponding metabolic pathways. In turn, metabolic flux influences epigenetic regulation by affecting the biosynthetic balance of enzyme cofactors or donors for certain chromatin modifications. Recently, non-enzymatic covalent modifications (NECMs) by chemically reactive metabolites have been reported to manipulate chromatin architecture and gene transcription through multiple mechanisms. Here, we summarize these recent advances in the identification and characterization of NECMs on nucleic acids, histones, and transcription factors, providing an additional mechanistic link between metabolism and epigenetics.
