Decades of research has stunned us with the very distinctive anatomy and physiology of our brain, and on the other hand, its complexity has always posed great difficulty in treating its dysfunction or damage. Understanding the brain under normal and, particularly in the diseased state, has always been very challenging and would have been impossible without proteomics. Neuroproteomic techniques have been extensiv Read More

Alzheimer’s disease (AD) is a progressive brain disorder and one of the most common causes of dementia and death. AD can be of two types; early-onset and late-onset, where late-onset AD occurs sporadically while early-onset AD results from a mutation in any of the three genes that include amyloid precursor protein (APP), presenilin 1 (PSEN 1) and presenilin 2 (PSEN 2). Biologically, AD is defined by the presence of th Read More

Changes in protein structure and function, alteration in protein-protein interaction, and significant difference in protein concentration inside the body could play an important role in indicating the pathological evidence of abnormalities before the development of clinical symptoms and act as a critical detection and diagnostic tool commonly known as biomarkers. Biomarkers play important roles in the diagnosis of various chro Read More

Alzheimer’s disease (AD) is characterized by deposition of amyloid-β protein aggregates and an appropriate treatment strategy is urgently needed, as the number of diagnosed cases continues to increase. The management of AD and other brain-associated diseases is limited by the blood brain barrier and its selective control of drug passage. In fact, most of the promising drugs have restricted curative effects on AD owing to the Read More

The ubiquitin (Ub)-proteasome system (UPS) targets various cellular proteins for degradation. It has been found that defects in the UPS play a crucial role in the pathogenesis of Alzheimer's disease (AD), as the existence of Ub immunoreactivity in AD-linked neuronal inclusions, including neurofibrillary tangles, is observed in all types of AD cases. Current investigations have shown that components of the UPS can be conne Read More

Neurodegenerative diseases are caused by progressive lesions or loss of specific nerve cells, which endanger human health. However, the mechanism by which neurodegeneration manifests remains unclear. Proteomics can shed light on this question as well as help establish diagnostic standards and discover new drug targets. The power of proteomics for understanding neurodegenerative diseases has increased substa Read More

Huntington’s disease (HD) is a neurodegenerative disease that is genetically inherited through an autosomal dominant gene located on chromosome 4. HD is caused by DNA mutation (generally 37 or more repetition of CAG nucleotides) that leads to an excessive stretch of glutamine residues. However, the main pathogenesis pathway resulted by polyglutamine expansion in mutant HD is unknown. The characteristics o Read More

Background: Parkinson´s disease (PD) and depression have an interplay at multiple cellular levels, a phenomenon which is translated into clinical data showing that depressive patients presented an enhanced risk for developing PD. The pathogenesis of both diseases is under intensive debate as correlated to dysregulations related to Ca2+ signaling. Objective: Then, revealing this interplay between these diseases may provide Read More

The chloroplast is a type of subcellular organelle of green plants and eukaryotic algae, which plays an important role in the photosynthesis process. Since the function of a protein correlates with its location, knowing its subchloroplast localization is helpful for elucidating its functions. However, due to a large number of chloroplast proteins, it is costly and time-consuming to design biological experiments to recognize subchloropl Read More

Peptides act as promising anticancer agents due to their ease of synthesis and modifications, enhanced tumor penetration, and less systemic toxicity. However, only limited success has been achieved so far, as experimental design and synthesis of anticancer peptides (ACPs) are prohibitively costly and time-consuming. Furthermore, the sequential increase in the protein sequence data via highthroughput sequenci Read More
