Glucocorticoids (GCs) cause cell cycle arrest and apoptosis in lymphoid cells which is exploited to treat lymphoid malignancies. The mechanisms of these anti-leukemic GC effects are, however, poorly understood. We previously defined a list of GC-regulated genes by expression profiling in children with acute lymphoblastic leukemia (ALL) during systemic GC monotherapy and in experimental systems ...
Adult T-cell acute lymphoblastic leukemia (T-ALL) has a poor prognosis. Although it has been found that activation of Notch1 signaling occurs in >50% T-ALL patients, γ-secretase inhibitors that target Notch1 signaling are of limited efficacy. However, c-Myc is an important direct target of Notch1 and, thus, c-Myc is another potential therapeutic target for T-ALL. Valproic acid (VPA), a histone ...
Neocarzinostatin (NCS) is an acidic protein (molecular weight, 10,700) isolated from Streptomyces carzinostaticus that has antitumor activity both in model rodent systems and in humans. In vitro it inhibits the growth of a human lymphoblastic leukemic cell line (CCRF-CEM) at a very low concentration (the amount of drug that causes a 50% inhibition of growth compared to control cultures as extra...
Perairan Teluk Kupang memiliki potensi ikan yang cukup melimpah. Beberapa alat tangkap beroperasi di tergolong kurang ramah lingkungan yakni bagan. Untuk menyikapi permasalahan tersebut dalam upaya untuk menjaga kelestarian sumberdaya ikan, maka,perlu memperhatikan aspek teknologi penangkapan digunakan sesuai dengan tata laksana perikanan bertanggung jawab (Code of Conduct for Responsible Fishe...
interpret and analyze the resulting model. Autoregressive integrated moving average (ARIMA) models, which encompass RW, random-trend models; auto-regressive models; and exponential weighted moving averages are linear time series models that have been quite popular thanks to their ability to exploit temporal dependence in prediction errors (4, 5). Linear models that exploit both spatial and temp...
In many acute leukemias, normal differentiation does not occur. However, in many cell lines derived from hematologic malignancies, differentiation or apoptosis can be induced by variety of agents. Despite advances in the treatment of Acute Lymphoblastic Leukemia (ALL), in most patients long-term survival rates remain unsatisfactory, especially in T-cell derived ALL. Thus we studied the anti-can...
Cytotoxicity, mode of action and antibacterial activities of selected Saudi Arabian medicinal plants
BACKGROUND The flora of Saudi Arabia is one of the richest biodiversity areas in the Arabian Peninsula and comprises very important genetic resources of crop and medicinal plants. The present study was designed to investigate the cytotoxicity and the antibacterial activities of the organic extracts from twenty six Saudi Arabian medicinal plants. The study was also extended to the investigation ...
BACKGROUND Relapsed T-lineage acute lymphoblastic leukemia (T-ALL) has been an incurable disease. Recent reports showed that an L-arginine depleting enzyme, pegylated arginase (BCT-100) may be effective against T-ALL cells. On the other hand, studies including ours had shown the symbiosis of ALL blasts and human mesenchymal stromal cells (hMSCs) in bone marrow microenvironment during L-asparagi...
