Item Calcium channelopathies in neurodegenerative disorder: an untold story of RyR and SERCA(Taylor and Francis Ltd., 2023-11-16T00:00:00) Dhureja, Maanvi; Arthur, Richmond; Soni, Divya; Upadhayay, Shubham; Temgire, Pooja; Kumar, PuneetIntroduction: Recent neuroscience breakthroughs have shed light on the sophisticated relationship between calcium channelopathies and movement disorders, exposing a previously undiscovered tale focusing on the Ryanodine Receptor (RyR) and the Sarco/Endoplasmic Reticulum Calcium ATPase (SERCA). Calcium signaling mainly orchestrates neural communication, which regulates synaptic transmission and total network activity. It has been determined that RyR play a significant role in managing neuronal functions, most notably in releasing intracellular calcium from the endoplasmic reticulum. Areas covered: It highlights the involvement of calcium channels such as RyR and SERCA in physiological and pathophysiological conditions. Expert opinion: Links between RyR and SERCA activity dysregulation, aberrant calcium levels, motor and cognitive dysfunction have brought attention to the importance of RyR and SERCA modulation in neurodegenerative disorders. Understanding the obscure function of these proteins will open up new therapeutic possibilities to address the underlying causes of neurodegenerative diseases. The unreported RyR and SERCA narrative broadens the understanding of calcium channelopathies in movement disorders and calls for more research into cutting-edge therapeutic approaches. � 2023 Informa UK Limited, trading as Taylor & Francis Group.Item Repurposing artemisinins as neuroprotective agents: a focus on the PI3k/Akt signalling pathway(Springer Science and Business Media Deutschland GmbH, 2022-12-05T00:00:00) Arthur, Richmond; Navik, Umashanker; Kumar, PuneetArtemisinin and its derivatives, since their discovery by professor Tu Youyou in the early 1970s, have been the bedrock for the management of malaria globally. Recent works have implied that they could be used to manage other diseases including neurodegenerative disorders. Neurodegenerative disorders mainly occur in the adult population resulting from a progressive deterioration of neuronal structures. These include Parkinson�s disease (PD), Alzheimer�s disease (AD), Huntington�s disease (HD), and Multiple sclerosis (MS), among others. The PI3K/Akt signaling pathway plays a significant role in the central nervous system. It has been investigated extensively for its role in central nervous system physiological processes such as cell survival, autophagy, neuronal proliferation, and synaptic plasticity. Therefore, the modulation of this pathway will be crucial in the management of neurodegenerative disorders. This review seeks to compile most of the research findings on the possible neuroprotective role of artemisinins with special emphasis on their modulatory role on the PI3k/Akt pathway. A literature survey was conducted on PubMed, EBSCO, Web of Science, and EMBASE using the keyword artemisinins, and a total of 10,281 articles were retrieved from 1956 to 2022. Among these, 120 articles were examined using Mesh words like PI3k/Akt, neurodegeneration, and neuroinflammation coupled with boolean operators. Most research revealed that artemisinins could help neurodegenerative disorders by modulating the PI3k/Akt with subsequent inhibition of oxidative stress, neuroinflammation, and apoptosis. This paper illustrates that artemisinins could be repurposed as a neuroprotective agent. � 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.Item Ferulic acid ameliorates neurodegeneration via the Nrf2/ARE signalling pathway: A Review(Elsevier B.V., 2022-10-30T00:00:00) Singh, Surbhi; Arthur, Richmond; Upadhayay, Shubham; Kumar, PuneetBackground: Ferulic acid is a polyphenolic phytoconstituent synthesized from the metabolism of amino acids phenylalanine and tyrosine found in fruits and vegetables. Neurodegenerative disorders have been a thorn in the flesh of neuroscientists owing in part to the increase in the aged population. Several drugs used in the management of these disorders are either ineffective or come with unbearable side effects. We present a review of ferulic acid focusing on leveraging its antioxidant property in an attempt to explain its role in neurodegenerative disorders. Basic procedure: data were obtained by perusing scientific databases including Web of Science and PubMed. It was realised that 18,000 articles were associated with ferulic acid from 1960-to 2022. We narrowed it down using the keywords neuroprotection, and antioxidant of which we had 239 articles. Main findings: results indicated that ferulic acid has wide neuropharmacological applications due to its antioxidant, anti-inflammatory, neuroprotective and antiapoptotic effects among others. The neuroprotective effect of ferulic acid has been studied in many diseases like Alzheimer's, Epilepsy, and Parkinson's disease. Principal conclusion: the neuroprotective potential of FA may be due to its ability to absorb active forms of oxygen and nitrogen and use redox-bearing compounds to regulate genetic expression including, encoding for antioxidant enzymes, the anti-apoptotic protein family Bcl-2, and pro-survival neurotrophic factors like BDNF. Its higher bioavailability and lipophilic nature make it a better drug candidate than other polyphenols for neurological disorders. � 2022 The Author(s)
