Glucose Metabolism and the Warburg Effect
Why do cancer cells produce lactic acid?
Lactic acid, commonly generated by cancers via reprogrammed energy metabolism (ie aerobic glycolysis, increased glutaminolysis), has a critical role in their growth as an immunosuppressive metabolite as well as a promoter of angiogenesis.
Why do cancer cells take up more glucose?
First, tumor cells trick fat cells into over-producing a protein called IGFBP1. This protein makes healthy cells less sensitive to insulin, meaning that when IGFBP1 is high, it takes more insulin to use glucose than it does when IGFBP1 is low.
What cancers cause high lactic acid?
Most reported cases of type B lactic acidosis are associated with hematological malignancies. Multiple case reports have been reported with patients of multiple myeloma,21 lymphoma, and leukemia22 complicated by type B lactic acidosis.
Is lactic acid good for cancer?
Summary: A team of researchers has found that lactic acid is an important energy source for tumor cells. In further experiments, they discovered a new way to destroy the most hard-to-kill, dangerous tumor cells by preventing them from delivering lactic acid.
What foods starve cancer cells?

What level of lactic acid indicates sepsis?
Since the serum lactate level was decreased to 2 mmol/L, serum lactate level is a more sensitive marker for septic shock. Notably, serum lactate level >2 mmol/L indicates a condition that is similar to sepsis with low BP in this issue of Journal of the American Medical Association (JAMA) (3).
What are the symptoms of lactic acidosis?
The symptoms of lactic acidosis include abdominal or stomach discomfort, decreased appetite, diarrhea, fast, shallow breathing, a general feeling of discomfort, muscle pain or cramping, and unusual sleepiness, tiredness, or weakness. If you have any symptoms of lactic acidosis, get emergency medical help right away.
What does high lactic acid levels mean?
A high lactic acid value means lactic acidosis, which can be caused by: Severe loss of water from the blood (dehydration). Blood problems, such as severe anemia or leukemia. Liver disease or liver damage that prevents the liver from breaking down lactic acid in the blood.
Can cancer cause elevated lactate?
Lactate Production Increases in Cancer
A common feature of primary and metastatic cancers is increase in glycolysis rate, leading to augmented glucose uptake and lactate formation, even under normal oxygen conditions. This is also known as aerobic glycolysis or the “Warburg effect” , a metabolic hallmark of cancer.
Does lactic acid damage cells?
While lactic acid is capable of scavenging some damaging free radicals, the extent of scavenging may not be sufficient to protect cells. Instead enough reactive radicals may remain in the culture system to damage, and ultimately kill cells.
Can cancer cause lactic acidosis?
Patients with cancer have many risk factors for developing lactic acidosis, including the diagnosis of cancer itself. The higher rate of glycolysis, the meta- bolic pathway that converts glucose to pyruvate, is characteristic of cancer.
