High-dose chemotherapy (HDC) is a regimen of chemotherapy medicines given at larger dosages. This therapeutic strategy is used to treat some cancers, especially those that are aggressive or have a high chance of coming back. With increased doses of chemotherapy chemicals administered to the body, HDC seeks to optimize the death of cancer cells.
The disease was first clinically linked to the glycine cleavage system in 1969. [10] Early studies showed high levels of glycine in blood, urine and cerebrospinal fluid. Initial research using carbon labeling showed decreased levels of CO 2 and serine production in the liver, pointing directly to deficiencies glycine cleavage reaction. [ 11 ]
While the high-dose chemotherapy and bone marrow transplant treatment is known for its impact on breast cancer, the treatment is presently used to treat other types of cancer, including testicular cancer, neuroblastoma, multiple myeloma, and various types of leukemias and lymphomas, like Hodgkin and non-Hodgkin Lymphoma.
Sequential high-dose chemotherapy is a chemotherapy regimen consisting of several (2 to 4) sequential monochemotherapies with only one chemotherapeutic agent per course. The idea behind this approach is that when using single-agent chemotherapy, the doctor can easily escalate the dose of the drug to the maximum tolerable dose by the patient, avoiding additive hematological toxicity from ...
Glycine (symbol Gly or G; [6] / ˈ ɡ l aɪ s iː n / ⓘ) [7] is an amino acid that has a single hydrogen atom as its side chain. It is the simplest stable amino acid ( carbamic acid is unstable). Glycine is one of the proteinogenic amino acids .
Downregulation of glycine-N-methyltransferase has been linked to hepatocellular carcinoma and pancreatic cancer. Serving this as a reliable marker for oncogenesis. [ 22 ] When compared to patients with deletions in GNMT, patients with no deletions early-stage pancreatic cancer had twice the median months overall survival.
As a result, the concentration of bile acids/salts in the small intestine is high enough to form micelles and solubilize lipids. "Critical micellar concentration" refers to both an intrinsic property of the bile acid itself and amount of bile acid necessary to function in the spontaneous and dynamic formation of micelles. [ 9 ]
Glycine encephalopathy is a rare autosomal recessive disorder of glycine metabolism. After phenylketonuria, glycine encephalopathy is the second most common disorder of amino acid metabolism. The disease is caused by defects in the glycine cleavage system, an enzyme responsible for glycine catabolism. There are several forms of the disease ...
