Elevated tissue expression of hyaluronic acid and hyaluronidase validates the hyaluronic acid-hyaluronidases urine test for bladder cancer. [48] Limited data support a role of lysosomal hyaluronidases in metastasis, while other data support a role in tumor suppression. Other studies suggest no contribution or effects independent of enzyme activity.
The fixed-dose combination of pertuzumab, trastuzumab, and hyaluronidase was approved for medical use in the United States in June 2020. [5] [10]The FDA's approval was based on the results of a non-inferiority study in participants with HER2-positive early breast cancer, which demonstrated the fixed-dose combination of pertuzumab, trastuzumab, and hyaluronidase had comparable efficacy and ...
The enzyme hyaluronate lyase (EC 4.2.2.1) catalyzes the chemical reaction. Cleaves hyaluronate chains at a β-D-GalNAc-(1→4)-β-D-GlcA bond, ultimately breaking the polysaccharide down to 3-(4-deoxy-β-D-gluc-4-enuronosyl)-N-acetyl-D-glucosamine
This gene encodes a lysosomal hyaluronidase. Hyaluronidases intracellularly degrade hyaluronan, one of the major glycosaminoglycans of the extracellular matrix. Hyaluronan is thought to be involved in cell proliferation, migration and differentiation. This enzyme is active at an acidic pH and is the major hyaluronidase in plasma.
NCI Drug Dictionary. National Cancer Institute. National Cancer Institute. Clinical trial number NCT00950300 for "A Study to Compare Subcutaneous (SC) Versus Intravenous (IV) Administration of Herceptin (Trastuzumab) in Women With Human Epidermal Growth Factor Receptor (HER) 2-Positive Early Breast Cancer" at ClinicalTrials.gov
As hyaluronidase deficiency is an extremely rare disorder, a clear clinical picture of the disease has not been formed. However, the following symptoms may occur: [2] Multiple soft tissue masses which may experience temporary episodes of painful swelling. Temporary episodes of generalized cutaneous swelling. Frequent episodes of otitis media.
In cell biology, a biomarker is a molecule that allows the detection and isolation of a particular cell type (for example, the protein Oct-4 is used as a biomarker to identify embryonic stem cells). [33] In genetics, a biomarker (identified as genetic marker) is a DNA sequence that causes disease or is associated with susceptibility to disease ...
Clinical trial number NCT05232825 for "A Phase III, Non-Inferiority, Randomized, Open-Label, Parallel Group, Multicenter Study To Investigate The Pharmacokinetics, Pharmacodynamics, Safety And Radiological And Clinical Effects Of Subcutaneous Ocrelizumab Versus Intravenous Ocrelizumab In Patients With Multiple Sclerosis (Ocarina II)" at ClinicalTrials.gov
