Integrated Proteomics and Lipidomics Analysis

Service Details
Case Study

Lipidomics，as an critical branch of metabolomics can effective reveal the relationship between lipid metabolism and life activities. Proteomes are all the proteins expressed by a organism. Proteomics is the science that analyzes the composition of proteins and their activity patterns in an organism, tissue or cell at the overall level. Changes in protein content play an important role in the growth of an organism, environmental stress, disease development and other processes.

The integrated analysis of proteomics and lipidomics can establishes the relationship between data at different levels of molecules. At the same time, combined with functional analysis, metabolic pathway enrichment, molecular interactions and other biofunctional analyses, it will offer researchers more systematically and comprehensively analyze the functions and regulatory mechanisms of biomolecules, and screen the key biological pathways or genes, lipid metabolites and proteases, etc., so as to ultimately achieve a comprehensive understanding of the general trend and direction of biological changes, and then put forward the model of the mechanism of change in molecular biology, which will promote the in-depth analysis and application of the subsequent research and application.

Advantages of integrated proteomics and lipidomics analysis

Integrates different levels of biological information. Proteomics focuses on protein expression, modification and interactions, while lipidomics focuses on lipid molecules composition and metabolism. Combined analysis can provide information at both protein and lipid levels, leading to a more comprehensive understanding of biological systems' functions and regulatory mechanisms.
Provide complementary information. Through integrated analysis, the interrelationships between proteins and lipids, such as protein-lipid interactions and lipid-protein modifications, can be revealed, leading to a better understanding of their functions in biological processes.
Improve biomarker discovery. Integrative analysis can provide more information and identify key markers missed by individual histological approaches. This can improve biomarker discovery rates and accuracy.
Enhanced understanding of disease mechanisms. Integrated analysis can reveal the interactions and regulatory mechanisms of proteins and lipids during disease development, and provide deeper insights into disease diagnosis and treatment.
Supporting individualized medicine. The combined analysis of proteins and lipids in individual samples can provide insights into differences between individuals. This can establish the basis for personalized diagnosis and treatment.

Integrated Lipidomics and Proteomics Point to Early Blood-Based Changes in Childhood Preceding Later Development of Psychotic Experiences: Evidence From the Avon Longitudinal Study of Parents and Children

Journal: Biol Psychiatry

Published: 2019

Abstract

Identifying early biomarkers of psychotic experiences (PE) is of interest because early diagnosis and treatment of individuals at risk for future illness is associated with improved outcomes. In this study, the authors investigated early lipidomic and coagulation pathway protein profiles of late-stage PE in subjects from the Avon Longitudinal Study of Parents and Children cohort through an integrated and targeted lipidomic and semi-targeted proteomic approach. Used to help investigators identify and treat subjects with psychiatric disorders (both psychotic and affective) early and significantly improve their clinical outcomes.

Results

Integrated lipidomic and proteomic analyses revealed that coagulation and complement pathway proteins are closely related functionally. The authors included complement protein levels from the total dataset with available data in the integrated lipid and protein analysis. The regularized canonical correlation analysis revealed that 17 lipids have a positive correlation with six proteins (PLG, heparin cofactor 2, complement C2, complement factor H, clusterin, and vitronectin), which exceeded a similarity score higher than 0.3. The coagulation protein PLG, the heparin cofactor 2, and the complement pathway protein blebbins were strongly and positively correlated with 16 lipids (Figure 1).

Figure 1

The KODAMA algorithm was applied to all individuals with available clinical data ( n = 90) in order for the authors to detect potential metabolic phenotypes present in the study population. Thereafter, the KODAMA scores were partitioned around centroid clustering to identify potentially similar phenotypes in this study population. Four distinct clusters were identified based on the highest profile median, named A, B, C, and D. The incidence of PE was significantly different between clusters ( p = .007) (Figure 2).

Figure 2

Conclusion

The findings that the lipidome and proteome of subjects reporting PE at 18 years of age were altered by 12 years of age suggest that metabolic dysregulation may contribute to early susceptibility to PE and suggest crosstalk between these lysophosphatidylcholine, phosphatidylcholine, and coagulation and complement proteins.

From Our Clients

"I recently used their proteomics service for a project analyzing protein interactions in yeast models. The team was very responsive and helped clarify the methodology they employed, which made me feel confident in the results. The data quality was solid, with clear identification of several key proteins involved in our study. Their thorough analysis enabled me to pinpoint specific interactions that I hadn't considered before, which significantly improved the direction of my research. I appreciate their professionalism and support throughout the process."

Sarah Thompson, University of California, Berkeley

"Our lab collaborated with them on a project studying cancer biomarkers. The proteomics analysis provided was detailed and focused, specifically highlighting the differential expression of proteins between healthy and tumor samples. Their clear explanations of the data helped my team understand the biological implications. I also appreciated their willingness to revise the reports based on our feedback, ensuring that we had everything we needed for our publication. This collaborative spirit was invaluable."

Emily Rodriguez, Stanford University

"Our lab worked with them on a project studying the effects of diet on gut microbiota using proteomics. They used a label-free quantification method to analyze proteins in fecal samples before and after dietary intervention. The results showed significant changes in protein expression linked to microbial activity. This was pivotal for our hypothesis about diet-microbiota interactions. The clarity of their data presentation made it easy for our team to integrate these findings into our ongoing research."

Dr. Lisa Wong, University of Toronto

"My experience with Creative Proteomics during the mass spectrometry analysis was excellent. We sent in human saliva and mouse brain tissue samples, which they expertly analyzed using both LC-MS and GC-MS techniques. The results were invaluable, revealing key metabolites in the saliva and identifying biomarkers linked to brain function in the brain tissue."
