Hyperglycemic memory in metabolism and cancer
Hormone Molecular Biology and Clinical Investigation
|May 27, 2016
Summary
Hyperglycemic memory, where high blood sugar epigenetically alters genes, drives diabetic complications and cancer risk even after glucose control. This review explores its molecular basis in metabolism and cancer.
Area of Science:
- Endocrinology
- Molecular Biology
- Oncology
Background:
- Hyperglycemia is a key feature of type 1 and type 2 diabetes mellitus.
- Prolonged hyperglycemia can cause lasting epigenetic changes in gene expression, known as hyperglycemic memory.
- This metabolic memory contributes to diabetic complications like retinopathy, hypertension, and nephropathy.
Purpose of the Study:
- To review current understanding of hyperglycemic memory.
- To explore the molecular mechanisms of hyperglycemic memory in metabolism and cancer.
Main Methods:
- Literature review of recent evidence on hyperglycemic memory.
- Analysis of molecular mechanisms linking hyperglycemia, epigenetics, and cellular changes.
Main Results:
- Hyperglycemic memory persists after glucose control, driving diabetic complications.
- Cancer cells are significantly affected by hyperglycemic memory in diabetic patients.
- Epigenetic modifications are central to the sustained effects of hyperglycemia.
Conclusions:
- Hyperglycemic memory plays a crucial role in the pathophysiology of diabetic complications.
- Understanding these mechanisms is vital for developing targeted therapies for diabetic cancer patients.
- Further research into the molecular underpinnings of metabolic memory is warranted.

01:19Overview of Carbohydrate Metabolism
4.2K
Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

1.2K
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...

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

8.2K
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...
