Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] The application of Matriptase, the Matriptase is applied in the diagnosis and treatment of chronic lymphocytic leukemia. see figure 1 As shown, the Matriptase includes a short intracellular segment, a transmembrane region, a SEA region (sea urchin sperm protein, enteropeptidase, agrin domain), two CUB regions (Cls / Clr, urchin embryonic growth factor and bone morphogenetic protein-1), four low-density lipoprotein receptor (LDLRA) domains, and a C-terminal trypsin-like protease region, the Matriptase is used in the diagnosis and treatment of chronic lymphocytic leukemia.

[0023] Further, the Matriptase is used as a diagnostic index for chronic lymphocytic leukemia.

[0024] Further, the Matriptase serves as a new target for the treatment of chronic lymphocytic leukemia.

[0025] The specific implementation process:

Abstract

The invention discloses an application of Matriptase. The Matriptase comprises a short intracellular segment, a transmembrane region, an SEA (sea urchin sperm protein, enteropeptidase, agrin domain) region, two CUB (Cls / Clr, urchin embryonic growth factor and bone morphogenetic protein-1) regions, four low density lipoprotein acceptor domains and a C-terminal trypsin-like protease region. The Matriptase is applied to diagnosis and treatment of chronic lymphocyte leukemia. By an experiment, bone marrows and peripheral blood specimens of normal people and leukemia sufferers are collected, and the detection result shows as follows: Matriptase mRNA and protein are highly expressed in the chronic lymphocyte leukemia sufferers, the expression level of Matriptase of the surface of lymphocyte can serve as a molecular marker for diagnosis of chronic lymphocyte leukemia, and the Matriptase can serve as a novel target for diagnosis and treatment of chronic lymphocyte leukemia.

Description

[0001] technical field [0002] The invention relates to the field of biotechnology, specifically, the role of Matriptase in the diagnosis, treatment, curative effect evaluation and prognosis of chronic lymphocytic leukemia. Background technique [0003] Leukemia is a malignant blood tumor, and its incidence rate is increasing year by year. Among them, chronic lymphocytic leukemia is a blood tumor in which B-lineage lymphocytes resist apoptosis and clonally accumulate in lymphoid tissue, bone marrow and peripheral blood, eventually leading to normal hematopoietic failure. . The incidence of chronic lymphocytic leukemia in Western countries is about 30% of all leukemias, and the incidence in China and Asian countries is less than 10%, and it has been increasing in recent years. Chronic lymphocytic leukemia cells are characterized by strong viability and inhibited apoptosis, and its pathogenesis is still unclear. Therefore, it is of great significance and clinical value to ...
