It does so by deglycosylating the vitamin D3-binding protein (Gc-protein), which is the precursor to macrophage-activating factor (MAF). Normally, Gc-protein undergoes a process where specific sugar residues are removed, leading to the production of MAF. However, when nagalase removes the entire trisaccharide from Gc-protein, the conversion to MAF is blocked, resulting in immunosuppression.<\/p>\n    <\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-a45acbd e-flex e-con-boxed e-con e-parent\" data-id=\"a45acbd\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-b628bf4 elementor-widget elementor-widget-text-editor\" data-id=\"b628bf4\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3 data-pm-slice=\"1 1 []\">Nagalase as a Tumor Marker<\/h3><p>Elevated nagalase activity has been observed in patients with a wide range of cancers, including:<\/p><ul data-spread=\"false\" data-pm-slice=\"3 1 []\"><li>Prostate, breast, colon, lung, esophagus, stomach, liver, pancreas, kidney, and bladder cancers<\/li><li>Testicular, uterine, and ovarian cancers<\/li><li>Mesothelioma, melanoma, fibrosarcoma, glioblastoma, neuroblastoma, and various leukemias<\/li><\/ul><p>The secretion of nagalase varies depending on tumor type, size, stage, malignancy, and invasiveness.

Studies indicate that nagalase measurements can detect cancerous lesions at levels below those detectable by other diagnostic methods. Notably, nagalase activity decreases significantly\u2014often to near-normal levels\u2014within 24 hours of surgical tumor removal, indicating its short half-life. This characteristic makes nagalase a valuable marker for assessing treatment efficacy.<\/p><h3>Nagalase in Viral Infections and Autoimmune Diseases<\/h3><p>In addition to its association with cancer, nagalase is also linked to viral infections and immune disorders. It is an intrinsic component of the envelope protein gp160 in HIV and the hemagglutinin (HA) protein in influenza virus. Additionally, increased nagalase activity has been detected in patients with systemic lupus erythematosus (SLE), an autoimmune disease.<\/p><h3 data-pm-slice=\"1 3 []\">Gc-MAF and Nagalase in Cancer Treatment<\/h3><p>Research has demonstrated that administering Gc-MAF (100 ng\/week) in cancer patients leads to a significant reduction in nagalase levels.
