Abnormal synaptic changes contribute to the majority of neurological diseases.

Focusing on the auditory system, Dr. Bao’s research group has been studying whether two ‘opposite disorders’, hearing loss and tinnitus, are both the result of abnormal synaptic changes that occur due to aging or early noise exposure. This group has been working to understand basic cellular and molecular mechanisms underlying these abnormal changes, employing a variety of molecular, behavioral, electrophysiological, and imaging methods. At the same time, the group has also explored translational opportunities to treat these disorders with pharmacogenomic approaches and stem cell therapies. Recently, the group discovered an effective means for eliminating or delaying hearing loss with drugs that are already approved by the U.S. Food and Drug Administration (FDA) for other indications. With funding from both the National Institutes of Health (NIH) and other sources, the group continues to explore basic mechanisms underlying these age-related disorders and other sources, the group continues to explore basic mechanisms underlying these age-related disorders and simultaneously develop both drug and stem cell therapies to treat these common diseases.

Based on recent seminal preclinical studies from Dr. Bao’s research group showing that antiepileptic drugs that block calcium channels effectively diminish presbycusis, a collaborative research project has been established to test whether the severity of age-related hearing loss is correlated with specific genetic variants in genes encoded for calcium signaling as well as whether causal genetic variants in the same genes associated with better hearing can be determined in elderly persons taking calcium channel blockers.  The long-term goal of this project is to develop a personalized medical intervention for presbycusis. The innovative aspect of this study is to apply pharmacogenetic approaches to discover personalized medications to prevent presbycusis.

In addition to Dr. Bao’s research group, a multidisciplinary team has been assembled that includes: Dr. Zhenyu Jia and Mike Hewit of NEOMED; Drs. Cliff Megerian, Gail Murray, and Qing Yin Zheng from Case Western Reserve University School of Medicine; and Drs. Nancy Tye-Murray and Jay F. Piccirillo from Washington University School of Medicine.  This project represents a unique opportunity that brings together a diverse team for the purpose of conducting translation research to improve health outcomes of patients at risk for presbycusis.

Regulation of Bone Mass in Alzheimer’s disease

  • Research in the C. Crish Lab centers on neurodegenerative mechanisms of osteoporosis in Alzheimer’s disease (AD). We are focused on identifying how central mechanisms that regulate bone growth may be affected by AD pathology, and how estrogen is synthesized in the brain may provide protective effects against both osteoporosis and AD.
  • Osteoporosis occurs in patients with AD at higher rates than in age and mobility-matched counterpart – amplifying health care complexities, disability and mortality.The relationship between these disorders may relate to a common mechanism where decreased bone mass is an early symptom of a neurodegenerative process.
  • Our lab is interested in determining how bone mineral density changes over time in a variety of Alzheimer’s mouse models that represent different pathological mechanisms of the disease.Our goal is to determine the temporal relationship between AD pathology and skeletal phenotype and if brain areas that regulate bone in these mice are damaged early in the progression of the disease. Additionally, we are interested in investigating the mechanisms by which AD disrupts central signaling that regulates bone mass.


Shared Neurodegenerative Mechanisms in Glaucoma and AD

  • Glaucoma is the leading cause of irreversible blindness worldwide, and over the past decade, our perspective on glaucoma has shifted from considering it solely an eye disease to identifying it as an age-related degenerative disorder of the central nervous system.
  • Mounting evidence suggests that glaucoma shares a number of epidemiological and mechanistic similarities with other age related neurodegenerations such as Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis (ALS), and Huntington’s disease. Therefore, mechanisms that play a role in the onset or progression of pathology in those diseases may also be relevant in glaucoma.

Research in the Crish Lab is concerned with pre-apoptotic changes occurring in glaucoma. Recently, as in other age-related neurodegenerative disorders, there have been a number of studies suggesting that functional deficits and compartmentalized degeneration occur well before cell death in glaucoma. It is unclear how much these pathologies produce the clinical symptoms characteristic to this disease or how they relate to eventual cell body loss.

We are most interested in exploring how defects in axonal transport, metabolism, and physiology:

  1. drive axonal and somatic degeneration;
  2. correlate to loss of function; and
  3. represent targets for interventions to improve outcome.

This research will serve to better define glaucoma’s progression and allow the development of more effective treatments.

Additionally, the Crish Lab studies naked mole-rats which are naturally blind fossorial rodents endemic to eastern Africa. We’re interested in evolutionary and developmentally degenerated visual systems and naked mole-rats are excellent for this research pursuit. And naked mole-rats are just plain interesting—we are also pursuing studies on their somatosensory system, social organization, reproduction and skeletal growth!

Our research primarily focuses on the development of neuroprotective and therapeutic strategies for the treatment of neurodegenerative diseases and psychiatric disorders. The research program is involved in elucidation of the oxidative stress, inflammation and energy dysregulation in the pathogenesis of neurological illnesses and investigating the therapeutic potential of antioxidants and anti-inflammatory as well as bioenergy substrates in neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease as well as psychiatric illnesses such as schizophrenia and post traumatic disorder. Of particular interest is the investigation of the pharmacological properties of natural products such as dietary polyphenols (resveratrol, curcumin and tea catechins and theaflavins). Additionally, we are interested in the elucidation of the neurochemical mechanisms involved in the neurotoxicity of amphetamines.

We also investigate the mechanism of action and receptor pharmacology of both typical, atypical and novel antipsychotic drugs. Of particular interest is the contribution of both dopaminergic and serotonergic receptors to the neurochemical effects and therapeutic potential of antipsychotic agents.

Preclinical studies utilize techniques such as in vivo microdialysis, HPLC, biochemical assays of neuronal metabolites and biomarkers as well as western blotting and northern blotting techniques.

Our research is focused on the translational aspects of the intermediary metabolism. In particular, we are interested in the pathophysiology of nonalcoholic fatty liver diseases (NAFLD), type 2 diabetes mellitus (T2DM) and their cardiovascular disease (CVD) related complications. We investigate insulin resistance, inflammation and oxidative stress-induced hepatic and cardiac mitochondrial dysfunctions, and abnormalities in the intermediary metabolism. We also study the role of metabolic syndrome in impaired lipoprotein biogenesis, remodeling and lipid transport implicated in atherosclerosis. We employ wide-range in vitro (isolated and reconstituted lipoproteins, cells and mitochondria) and in vivo (animal and human studies) models to explore these questions. Our projects heavily rely on the utilization of high resolution mass spectrometry-assisted metabolomics, and proteomics techniques coupled with the stable isotope-based flux studies.

Our current research projects include:

  • Regulation of the high density lipoprotein (HDL) metabolism in T2DM.
  • Investigation of the link between hepatic inflammation and atherosclerosis in NAFLD.
  • Exploration of the role of oxidative stress in hepatic mitochondrial dysfunction in NAFLD.
  • The effect of aging on cardiac mitochondrial dysfunction.

Metabolomics and Proteomics

We use targeted metabolomics to study alterations in the citric acid cycle, anaplerosis/cataplerosis, amino acid, fatty acid and sphingolipid metabolism. Our stable isotope-based flux studies investigate the temporal changes in metabolites and provide information on the activities of metabolic pathways.

We also apply static and dynamic proteomics approaches to investigate stability and turnover rates of proteins, and protein-protein interactions in health and diseases.

Our clinical studies are conducted in collaboration with Drs. McCullough, Dasarathy and Kashyap from CCF. We are also collaborating with Dr. Hoppel from CWRU to study cardiac mitochondrial dysfunction in aging heart and Dr. Sadygov from UTMB to develop bioinformatics tools to facilitate these studies.

Metabolic dysregulation in particular that of lipid metabolism is the primary focus of research in the Sadana laboratory. Reduced HDL-Cholesterol and elevated triglycerides are center piece of metabolic syndrome. Our laboratory is studying the role of angiopoietin-like 4 (ANGPTL4) in the regulation of lipid metabolism. ANGPTL4 has been shown to be a physiological inhibitor of lipoprotein lipase (LPL), the enzyme catalyzing the clearance of triglyceride rich lipoproteins in the blood stream. In particular, we are interested in hormonal and nutritional regulation of ANGPTL4 at the transcriptional and post-transcriptional levels. Our research will help elucidate the downstream effects of such signaling on lipid profile in humans. Further, we are also interested in developing small molecule therapeutics against drug targets in dysregulated lipid metabolism. We utilize a combination of molecular and cellular biology, pharmacology, chemical biology, assay development and drug screening approaches in our research.

Additionally, in collaborative research we are also pursuing the neuroprotective role of thyroid hormone in ischemic brain stroke. In particular, we are studying the mechanistic pathways of anti-edema action of thyroid hormone in ischemic stroke.

Our laboratory focuses on the molecular mechanisms underlying the development of alcoholic fatty liver, especially in two areas: the effects of ethanol on the signaling pathways of lipid metabolism regulations in the liver, and ethanol regulation of adiponectin, a hormone derived from adipocytes, and its hepatic signaling. Since the effects of ethanol, either directly on signaling molecules in liver or indirectly on adiponectin synthesis in adipose, can be manipulated by dietary fatty acids or pharmacological agents. Our studies may lead to novel therapeutic strategies for the treatment of alcoholic fatty liver diseases and possibly a cure for steatohepatitis.
