Huang P, Wan Z, Qu S. Targeting the RUNX3-miR-186-3p-DAT-IGF1R axis as a therapeutic strategy in a Parkinson's disease model. J Transl Med 2024; 22:719. [PMID: 39103832 DOI: 10.1186/s12967-024-05535-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Accepted: 07/22/2024] [Indexed: 08/07/2024] Open
Abstract
With the increasing age of the population worldwide, the incidence rate of Parkinson's disease (PD) is increasing annually. Currently, the treatment strategy for PD only improves clinical symptoms. No effective treatment strategy can slow down the progression of the disease. In the present study, whole transcriptome sequencing was used to obtain the mRNA and miRNA expression profiles in a PD mouse model, which revealed the pathogenesis of PD. The transcription factor RUNX3 upregulated the miR-186-3p expression in the PD model. Furthermore, the high miR-186-3p expression in PD can be targeted to inhibit the DAT expression, resulting in a decrease in the dopamine content of dopaminergic neurons. Moreover, miR-186-3p can be targeted to inhibit the IGF1R expression and prevent the activation of the IGF1R-P-PI3K-P-AKT pathway, thus increasing the apoptosis of dopaminergic neurons by regulating the cytochrome c-Bax-cleaved caspase-3 pathway. Our research showed that the RUNX3-miR-186-3p-DAT-IGF1R axis plays a key role in the pathogenesis of PD, and miR-186-3p is a potential target for the treatment of PD.

Abstract
The etiology of hearing impairment is multifactorial, with contributions from both genetic and environmental factors. Although genetic studies have yielded valuable insights into the development and function of the auditory system, the contribution of gene products and their interaction with alternate environmental factors for the maintenance and development of auditory function requires further elaboration. In this review, we provide an overview of the current knowledge on the role of redox dysregulation as the converging factor between genetic and environmental factor-dependent development of hearing loss, with a focus on understanding the interaction of oxidative stress with the physical components of the peripheral auditory system in auditory disfunction. The potential involvement of molecular factors linked to auditory function in driving redox imbalance is an important promoter of the development of hearing loss over time.

Enzyme Microb Technol 2024; 172:110310. [PMID: 37925770 DOI: 10.1016/j.enzmictec.2023.110310] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 08/01/2023] [Accepted: 08/27/2023] [Indexed: 11/07/2023]
Abstract
Bacillus licheniformis 2709 is the main industrial producer of alkaline protease (AprE), but its biosynthesis is strictly controlled by a highly sophisticated transcriptional network. In this study, the UP elements of aprE located 74-98, 98-119 and 140-340 bp upstream of the transcriptional start site (TSS) were identified, which presented obvious effects on the transcription of aprE. To further analyze the transcriptional mechanism, the specific proteins binding to the approximately 500-bp DNA sequences were subsequently captured by reverse-chromatin immunoprecipitation (reverse-ChIP) and DNA pull-down (DPD) assays, which captured the transcriptional factors CggR, FruR, and YhcZ. The study demonstrated that CggR, FruR and YhcZ had no significant effect on cell growth and aprE expression. Then, aprE expression was significantly enhanced by deleting a potential negative regulatory factor binding site in the genome. The AprE enzyme activity in shake flasks of the genomic mutant BL ∆1 was 47% higher than in the original strain, while the aprE transcription level increased 3.16 times. The protocol established in this study provides a valuable reference for the high-level production of proteins in other Bacillus species. At the same time, it will help reveal the molecular mechanism of the transcriptional regulatory network of aprE and provide important theoretical guidance for further enhancing the yield of AprE.

Front Neural Circuits 2021; 15:756184. [PMID: 34744640 PMCID: PMC8568317 DOI: 10.3389/fncir.2021.756184] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Accepted: 10/04/2021] [Indexed: 11/13/2022] Open
Abstract
AP-2 is a family of transcription factors involved in many aspects of development, cell differentiation, and regulation of cell growth and death. AP-2δ is a member of this group and specific gene expression patterns are required in the adult mouse brain for the development of parts of the inferior colliculus (IC), as well as the cortex, dorsal thalamus, and superior colliculus. The midbrain is one of the central areas in the brain where multimodal integration, i.e., integration of information from different senses, occurs. Previous data showed that AP-2δ-deficient mice are viable but due to increased apoptosis at the end of embryogenesis, lack part of the posterior midbrain. Despite the absence of the IC in AP-2δ-deficient mice, these animals retain at least some higher auditory functions. Neuronal responses to tones in the neocortex suggest an alternative auditory pathway that bypasses the IC. While sufficient data are available in mammals, little is known about AP-2δ in chickens, an avian model for the localization of sounds and the development of auditory circuits in the brain. Here, we identified and localized AP-2δ expression in the chicken midbrain during embryogenesis. Our data confirmed the presence of AP-2δ in the inferior colliculus and optic tectum (TeO), specifically in shepherd's crook neurons, which are an essential component of the midbrain isthmic network and involved in multimodal integration. AP-2δ expression in the chicken midbrain may be related to the integration of both auditory and visual afferents in these neurons. In the future, these insights may allow for a more detailed study of circuitry and computational rules of auditory and multimodal networks.
