Activators and Inhibitors of NRF2: A Review of Their Potential for Clinical Development

Oxidative Medicine and Cellular Longevity, Journal Year: 2019, Volume and Issue: 2019, P. 1 - 20

Published: July 14, 2019

The transcription factor NRF2 (nuclear erythroid 2-related 2) triggers the first line of homeostatic responses against a plethora environmental or endogenous deviations in redox metabolism, proteostasis, inflammation, etc. Therefore, pharmacological activation is promising therapeutic approach for several chronic diseases that are underlined by oxidative stress and such as neurodegenerative, cardiovascular, metabolic diseases. A particular case cancer, where confers survival advantage to constituted tumors, therefore, inhibition desired. This review describes electrophilic nonelectrophilic activators with clinical projection various We also analyze status inhibitors, which at this time provide proof concept blocking activity cancer therapy.

Rapid induction and long-term self-renewal of primitive neural precursors from human embryonic stem cells by small molecule inhibitors

Proceedings of the National Academy of Sciences, Journal Year: 2011, Volume and Issue: 108(20), P. 8299 - 8304

Published: April 27, 2011

Human embryonic stem cells (hESCs) hold enormous promise for regenerative medicine. Typically, hESC-based applications would require their in vitro differentiation into a desirable homogenous cell population. A major challenge of the current hESC paradigm is inability to effectively capture and, long-term, stably expand primitive lineage-specific stem/precursor that retain broad potential more importantly, developmental stage-specific propensity. Here, we report synergistic inhibition glycogen synthase kinase 3 (GSK3), transforming growth factor β (TGF-β), and Notch signaling pathways by small molecules can efficiently convert monolayer cultured hESCs neuroepithelium within 1 wk under chemically defined condition. These neuroepithelia self-renew presence leukemia inhibitory factor, GSK3 inhibitor (CHIR99021), TGF-β receptor (SB431542); high neurogenic responsiveness instructive neural patterning cues toward midbrain hindbrain neuronal subtypes; exhibit vivo integration. Our work uniformly captures maintains from hESCs.

GSK-3 Inhibitors: Preclinical and Clinical Focus on CNS

Frontiers in Molecular Neuroscience, Journal Year: 2011, Volume and Issue: 4

Published: Jan. 1, 2011

Inhibiting glycogen synthase kinase-3 (GSK-3) activity via pharmacological intervention has become an important strategy for treating neurodegenerative and psychiatric disorders. The known GSK-3 inhibitors are of diverse chemotypes mechanisms action include compounds isolated from natural sources, cations, synthetic small-molecule ATP-competitive inhibitors, non-ATP-competitive substrate-competitive inhibitors. Here we describe the variety with a specific emphasis on their biological activities in neurons neurological We further highlight our current progress development GSK-3. available data raise hope that one or more these drug design approaches will prove successful at stabilizing even reversing aberrant neuropathology cognitive deficits certain central nervous system

Sculpting Neural Circuits by Axon and Dendrite Pruning

Annual Review of Cell and Developmental Biology, Journal Year: 2015, Volume and Issue: 31(1), P. 779 - 805

Published: Oct. 5, 2015

The assembly of functional neural circuits requires the combined action progressive and regressive events. Regressive events encompass a variety inhibitory developmental processes, including axon dendrite pruning, which facilitate removal exuberant neuronal connections. Most pruning involves axons that had already made synaptic connections; thus, is tightly associated with synapse elimination. In many instances, these processes are regulated by interplay between neurons glial cells act instructively during remodeling. Owing to importance dendritic remodeling require precise spatial temporal control, this achieved range distinct molecular mechanisms. Disruption mechanisms results in abnormal has been linked brain dysfunction. Therefore, understanding will be instrumental advancing our knowledge disease mental disorders.

ABSTRACT Midbrain dopaminergic (mDA) neuron development has been an intense area of research during recent years. This is due in part to a growing interest regenerative medicine and the hope that treatment for diseases affecting mDA neurons, such as Parkinson's disease (PD), might be facilitated by better understanding how these neurons are specified, differentiated maintained vivo. knowledge help instruct efforts generate vitro, which holds promise not only cell replacement therapy, but also modeling drug discovery. In this Primer, we will focus on developments molecular mechanisms regulate vivo, they have used human vitro from pluripotent stem cells or somatic via direct reprogramming.
