Summary
Prolonged exposure to high blood sugar can epigenetically alter cells, creating a "memory" that hinders cell therapy for chronic heart disease. Epigenetic drugs show promise in treating metabolic disorders and related complications.
Area of Science:
- Cellular biology
- Epigenetics
- Metabolic disorders
Background:
- Prolonged exposure to hyperglycemia can epigenetically imprint human cells.
- This epigenetic memory poses a significant challenge for cell therapy in chronic heart disease due to required ex vivo expansion.
- The phenomenon involves stable epigenetic information leading to a diseased phenotype.
Purpose of the Study:
- To review mechanisms of epigenetic memory in hyperglycemia.
- To explore the implications of hyperglycemic memory for cell therapy.
- To summarize the use of epigenetic drugs in treating metabolic diseases.
Main Methods:
- Literature review of epigenetic mechanisms.
- Analysis of studies on cell therapy limitations.
- Survey of experimental, preclinical, and clinical applications of epigenetic drugs.
Main Results:
- Hyperglycemic memory involves stable epigenetic alterations.
- This memory can be transferred to descendant cells.
- Epigenetic drugs are being investigated for therapeutic potential.
Conclusions:
- Epigenetic memory of hyperglycemia is a critical factor in metabolic diseases and cell therapy.
- Understanding these mechanisms is key to developing effective treatments.
- Epigenetic therapies offer a promising avenue for managing diabetes and its complications.

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose...

28
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.

01:15Hypoglycemia and Glucagon
1.3K
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

01:27Glucose Homeostasis: Pancreatic Islets and Insulin Secretion
2.8K
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.

01:58Cell Specific Gene Expression
13.3K
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

01:26Type I Diabetes II: Pathophysiology
75
Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular...
