Abstract
Modulating role of circRNAs and microRNAs in neurobiological changes induced by drug exposure remains unclear. We examined alterations in some circRNAs and microRNAs in the striatum after morphine dependence and withdrawal and their associations with the changes in spatial working memory performance. Male Wistar rats were used in which 10 days morphine exposure induced dependence. Withdrawal effects were assessed 30 days after stopping morphine exposure. Spatial working memory was assessed using a Y maze test on days 1 and 10 of the drug exposure and 30 days after withdrawal. The gene and protein expression were assessed after dependence and withdrawal. The results revealed that 10 days morphine exposure impaired working memory, which partially reinstated after withdrawal. After 10 days morphine exposure, significant increases in Oprm1 gene and OPRM1 protein levels were detected, which persisted even after withdrawal. The expression of circOprm1 and miR-339-3p decreased in the morphine-dependent group, but they returned to normal levels after withdrawal. The expression of Tlr4 gene and TLR4 protein levels decreased after dependence. While Tlr4 mRNA levels returned to normal after withdrawal, TLR4 protein levels remained lower than the control group. In the morphine-dependent group, both Serpini1 and circSerpini expression significantly increased, but they restored after withdrawal. Expression of miR-181b-3p, miR-181b-5p, miR-181c-3p, and miR-181c-5p decreased after dependence, but they reinstated after withdrawal. It can be concluded that circOprm1 and circSerpini via regulating the OPRM1 and TLR4 expression in the striatum are associated with the neuroadaptation underlying spatial working memory after both morphine dependence and withdrawal.

A Review of the CACNA Gene Family: Its Role in Neurological Disorders. Diseases 2024; 12:90. [PMID: 38785745 PMCID: PMC11119137 DOI: 10.3390/diseases12050090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2024] [Revised: 04/25/2024] [Accepted: 04/28/2024] [Indexed: 05/25/2024] Open
Abstract
Calcium channels are specialized ion channels exhibiting selective permeability to calcium ions. Calcium channels, comprising voltage-dependent and ligand-gated types, are pivotal in neuronal function, with their dysregulation is implicated in various neurological disorders. This review delves into the significance of the CACNA genes, including CACNA1A, CACNA1B, CACNA1C, CACNA1D, CACNA1E, CACNA1G, and CACNA1H, in the pathogenesis of conditions such as migraine, epilepsy, cerebellar ataxia, dystonia, and cerebellar atrophy. Specifically, variants in CACNA1A have been linked to familial hemiplegic migraine and epileptic seizures, underscoring its importance in neurological disease etiology. Furthermore, different genetic variants of CACNA1B have been associated with migraine susceptibility, further highlighting the role of CACNA genes in migraine pathology. The complex relationship between CACNA gene variants and neurological phenotypes, including focal seizures and ataxia, presents a variety of clinical manifestations of impaired calcium channel function. The aim of this article was to explore the role of CACNA genes in various neurological disorders, elucidating their significance in conditions such as migraine, epilepsy, and cerebellar ataxias. Further exploration of CACNA gene variants and their interactions with molecular factors, such as microRNAs, holds promise for advancing our understanding of genetic neurological disorders.
