| Project Title: | Untargeted Metabolomics Reveals Unique Biomolecular Signatures in Overweight and Obesity Using UHPLC-ESI-QTOF-MS Analysis |
| Project Type: | LC-MS/MS |
| Project Summary: | Obesity poses a multifaceted challenge to global public health, impacting individuals and society in various ways. Apart from the heightened susceptibility to chronic conditions such as diabetes, cardiovascular diseases, obesity significantly escalates healthcare costs. Effective public health strategies are essential for addressing issues related to early detection, diagnosis, and personalized treatment plans. This emphasizes the crucial need for a deep understanding of biochemical pathways, patient monitoring, and prognosis. In this context, metabolomics has become a valuable approach, focusing on the identification of metabolites in biofluids and tissues.In this study, an untargeted metabolomics-based method was employed to investigate metabolomic changes and their relationship to pathways in overweight and obese individuals. Plasma samples were collected from 29 healthy individuals with normal weight, 17 overweight individuals, and 28 obese individuals who met the inclusion criteria for the study. The plasma samples were analyzed using highly sensitive ultra-high-performance liquid chromatography electrospray ionization quadrupole time-of-flight mass spectrometry. Pantothenic acid and L-proline showed increased levels in the overweight group, whereas phenylacetaldehyde and glycerophosphocholine were notably decreased compared to the normal weight group. Conversely, the obese group exhibited elevated levels of specific metabolites, including L-leucine, L-tryptophan, phenylalanine, and tyrosine. On the contrary, the obese group demonstrated decreased levels of other metabolites such as 2,3-Diaminopropionic acid, and phenylacetaldehyde. Additionally, significant changes in metabolic pathways, such as pantothenate and CoA biosynthesis, and beta-alanine metabolism, were observed in the overweight group. In contrast, the obese group displayed significant alterations in phenylalanine and tyrosine metabolism, tryptophan metabolism, and beta oxidation of very long-chain fatty acids. The present investigation sheds light on the potential diagnostic significance of certain metabolites in obesity and the impact of their level changes on specific metabolic pathways. Additional studies are necessary to confirm the association of these metabolites in obesity and to confirm their diagnostic value. |
