l-Asparaginase (E.C. 3.5.1.1) is used as a therapeutic agent in the treatment of acute childhood lymphoblastic leukemia. It is found in a variety of organisms such as microbes, plants and mammals. In plants, l-asparaginase enzymes are required to catalyze the release of ammonia from asparagine, which is the main nitrogen-relocation molecule in these organisms. An Indian medicinal plant, Withani...
BACKGROUND Extranodal natural killer (NK)/T-cell lymphoma, nasal type, and aggressive NK-cell leukemia are highly aggressive diseases with a poor outcome. PATIENTS AND METHODS We report a multicentric French retrospective study of 15 patients with relapsed, refractory, or disseminated disease, treated with L-asparaginase-containing regimens in seven French centers. Thirteen patients were in r...
Abstract Introduction L-asparaginase is considered to be the most important component in treatment of acute lymphoblastic leukemia (ALL). Intensifying use during for ALL has resulted a significant rise percentage children and adolescents who are cured disease. Asparaginase trough activity more than or equal 100 IU/L on day 7 been found desired level all childhood patients. Objectives Due paucit...
Genome mining revealed a 1011 nucleotide-long fragment encoding a type I L-asparaginase (J15 asparaginase) from the halo-tolerant Photobacterium sp. strain J15. The gene was overexpressed in pET-32b (+) vector in E. coli strain Rosetta-gami B (DE3) pLysS and purified using two-step chromatographic methods: Ni(2+)-Sepharose affinity chromatography and Q-Sepharose anion exchange chromatography. T...
Introduction L-asparaginase is an essential chemotherapeutic agent in the therapy of acute lymphoblastic leukemia (ALL), which has led to improvement survival. In low- and middle-income countries like India, outcomes ALL are inferior compared with published literature, one causes believed be due quality bioequivalent asparaginase. Objective The following survey attempts understand practice usin...
Background and purpose: L-asparaginase is a well-known enzyme that is used as one of the most effective anti-leukemic drugs. Considering that the asparaginases used as antitumor are bacterial-based enzymes, the aim of this study was to find indigenous potential bacteria producing asparaginase. Materials and methods: The enzyme producing bacteria was isolated from the agricultural soils aroun...
Introduction: The bacterial Asparaginase is used in the treatment of asparagine-dependent tumors, particularly lymphatic sarcoma and acute lymphoblastic leukemia. However, the instability of the enzyme increases the number of injections that are accompanied by high immune responses. The aim of this study was to investigate the conjugation of L-asparaginase with nanochitosan glutaraldehyde (NCG)...
Asparaginase is an enzyme used in the treatment of acute lymphoblastic leukemia and lymphoblastic lymphoma in children. It has minimal bone marrow toxicity. Its major side effects are anaphylaxis, pancreatitis, diabetes, coagulation abnormalities, and thrombosis, especially intracranial. It is derived from 2 different sources: Escherichia coli and Erwinia chrysanthemi. Nonrandomized clinical st...
Background: Asparaginase is an important component of pediatric acute lymphoblastic leukemia therapy. Unfortunately, this treatment is hampered by hypersensitivity reactions. In general, allergies cause complete inactivation of the drug, regardless of the severity. However, we report atypical allergic reactions without inactivation of asparaginase, here called allergic-like reactions. Procedure...
Abstract Tumor cells have different metabolism from normal cell, which is called as cancer metabolism. In cells, asparagine provided by synthetase (ASNS) aspartate. On the other hand, in tumor needed to be taken outside addition synthesized ASNS within because of rapid growth cells. Glioblastoma one aggressive brain tumors, and temozolomide frequently used. After glioblastoma acquire resistance...
