RPL26P13: A Potential Drug Target and Biomarker for ALS-related Neuronal Loss

Introduction

Amyloidosis, a neurodegenerative disease characterized by the accumulation of amyloidogenic protein beta (A尾), is a leading cause of dementia and other neurological disorders. The hallmark of amyloidosis is the progressive loss of neurons, which is a result of the neurotoxicity of A尾. Ribosomal protein L26 (RPL26) is a key protein involved in the generation of amyloid in neurofibrillary tangles, the hallmark of Alzheimer's disease (AD). Here, we discuss RPL26P13, a pseudogene encoding the RPL26 protein, as a potential drug target and biomarker for ALS -related neuronal loss.

The RPL26P13 Pseudogene

The RPL26 gene, located on chromosome 13, encodes a protein that plays a critical role in the generation of amyloid in neurofibrillary tangles. The protein is composed of 1,947 amino acids and contains several distinct domains, including a N-terminal transmembrane domain, a coiled -coil domain, and a C-terminal T-loop region. The RPL26 protein has been shown to interact with several protein partners, including the microtubule protein T-tubin and the protein kinase B-36.

The RPL26P13 Pseudogene is one of the pseudogenes associated with the RPL26 gene. It is a non-coding RNA molecule that has been shown to encode a protein with similar sequence to RPL26. The RPL26P13 pseudogene has been identified by bioinformatic analysis and is located in the 5'-end of the RPL26 gene.

The Potential Role of RPL26P13 as a Drug Target

The accumulation of A尾 in neurofibrillary tangles is a hallmark of Alzheimer's disease, and the neurotoxicity of A尾 has been linked to the progressive loss of neurons. RPL26 is a key protein involved in the generation of A尾 in neurofibrillary tangles, and its levels have been shown to be affected by various neurological disorders, including Alzheimer's disease. Therefore, targeting RPL26P13 may be a promising strategy for the development of therapeutic interventions for Alzheimer's disease.

Several studies have suggested that RPL26P13 can be targeted by small molecules. For example, a study by Srivastava et al. (2017) investigated the potential anti-A尾 neurotoxicity of a drug called 1,2-dimethoxybenzepril (1,2-DMB), a small molecule that inhibits the activity of A尾42, a highly aggregating form of A尾. The results of the study suggested that 1,2-DMB may have neuroprotective properties against A尾42-induced neurotoxicity.

Another study by Zhang et al. (2018) investigated the effects of a small molecule called 尾-amyloid on the expression of RPL26P13 and its associated proteins in primary human neuroepithelial cells. The results of the study demonstrated that the expression of RPL26P13 and its associated proteins was increased in 尾-amyloid-treated cells, and this increase was associated with the neurotoxicity of 尾-amyloid.

The Potential Role of RPL26P13 as a Biomarker

The RPL26P13 pseudogene has also been suggested as a potential biomarker for ALS-related neuronal loss. ALS is a progressive neurodegenerative disease that is characterized by the progressive loss of motor neurons. The hallmark of ALS is the progressive loss of neurons, which is a result of the neurotoxicity of A尾. Therefore, measuring the expression of RPL26P13 in brain tissue may be a promising strategy for the diagnosis and monitoring of ALS.

A study by Zhao et al. (2018) investigated the expression of RPL26P13 in ALS brain tissue and found that the expression levels were significantly decreased compared to control brain tissue. The results of the study suggested that RPL26P13 may be a potential biomarker for ALS- related neuronal loss.

Another study by Wang et al. (2020) investigated the expression of RPL26P13 in the CNS of individuals with ALS and found that the expression levels were decreased compared to healthy individuals. The results of the study suggested that RPL26P13 may be a potential biomarker for ALS -related neuronal loss.

Conclusion

RPL26P13 is a pseudogene associated with the RPL26 gene that encodes a protein involved in the generation of amyloid in neurofibrillary tangles. The accumulation of A尾 in neurofibrillary tangles is a hallmark of Alzheimer's disease, and the neurotoxicity of A尾 has been linked to the progressive loss of neurons. Therefore, targeting RPL26P13 may be a promising strategy for the development of therapeutic interventions for Alzheimer's disease. The potential of RPL26P13 as a drug target and biomarker for ALS-related neuronal loss makes it an attractive target for future research.
