Metabolism Antibodies

Metabolism is the chemical process catalyzed by certain enzymes which enables organisms to convert various substances to energy in order to sustain life. Metabolism antibodies are crucial for studying glucose, lipid, protein, and nucleotide metabolism.

It can be broken into two categories: catabolism and anabolism. Cellular respiration, for example, is a catabolic process as it breaks down substances. Building up nucleic acids and proteins, on the other hand, is anabolic. The citric acid cycle (pictured), also known as the Krebs cycle, is a crucial metabolic pathway that links fat, carbohydrate, and protein metabolism. Investigating metabolic pathways is important in epigenetic research to help understand diseases such as cancer and cardiovascular disorders, as well as metabolic disorders including diabetes, phenylketonuria, and hyperthyroidism.

Glucose metabolism antibodies are useful for investigating enzymes involved in metabolic pathways including glycolysis and gluconeogenesis, as well as proteins involved in the synthesis of glycosylated proteins and glycolipids. For example, unregulated glucose levels may lead to diabetes, therefore antibodies related to glucose metabolism can be useful for investigating this prolific disease. Various targets and proteins related to glycolysis include Glyceraldehyde 3-phosphate dehydrogenase (GAPDH), hexokinases such as Hexokinase 1 (HK1) and Hexokinase Domain Containing 1 (HKDC1), as well as pyruvate kinases such as PKM1 and PKM2, among many others.

Lipid metabolism antibodies may be used by epigenetic researchers investigating the synthesis of lipids from acetyl-CoA, known as lipogenesis, and the breakdown of lipids to produce energy, called lipolysis. For instance, research has connected lipid metabolism and histone methylation with changes in lifespan. Lipid metabolism has also been linked to developmental epigenetic programming, potentially impacting long-term health and disease risk. Popular targets connected to lipid metabolism include Apolipoprotein E (ApoE) and Scavenger Receptor Class B Member 1 (SCARB1).

Protein metabolism antibodies can help researchers study the synthesis of amino acids and proteins as well as the breakdown of proteins. For example, the maternal diet during pregnancy and nutritional epigenetics are topics of interest to epigenetic researchers, especially since amino acids are known to play key roles in providing methyl donors for DNA and protein methylation. Additionally, research suggests that maternal dietary protein restriction may affect covalent modifications of the fetal genome. Amino acids and related metabolic pathways are particularly involved in conditions such as metabolic syndrome and, combined with epigenetic insights, may offer new avenues for treatment such as dietary intervention.
