As a result, cells expressing different forms of BCR/ABL were recruited for the present study, including K562 (human wild‑type) or TCCY‑T315I (human imatinib‑resistant) and the Ba/F3‑(T315I/E279K/Y253H) (mouse BCR/ABL point mutation‑transfected cells). (spandidos-publications.com)
Thus, cells expressing different forms of BCR/ABL were recruited for the present study, including K562 [human wild-type (WT)] or TCCY-T315I [human imatinib-resistant (IR)] and the Ba/F3-(T315I/E279K/Y253H) (mouse BCR/ABL point mutation-tranfected cells). (spandidos-publications.com)

We generated a triple transgenic mouse model, in which tamoxifen-inducible Cre-recombinase targets expression of a constitutively nuclear transcription factor NFATC1 to FLT3 ITD positive HSC. (biomedcentral.com)

Because the BCR-Abl tyrosine kinase enzyme exists only in cancer cells and not in healthy cells, imatinib works as a form of targeted therapy-only cancer cells are killed through the drug's action. (keralapharmacist.com)

2020), Chronic Myeloid Leukemia is a myeloproliferative blood cancer, with an annual incidence in Japan of 0.5 cases per 100,000 population. (delveinsight.com)

Interestingly, AVM appeared to be more sensitive to imatinib‑resistant (T315I, Y253H, and E279K) than wild‑type BCR/ABL cells, indicating its potential to overcome imatinib‑resistant severe issues in CML. (spandidos-publications.com)

Some tumor cells, however, have a dependence on bcr-abl. (keralapharmacist.com)

According to http://en.wikipedia.org/wiki/Imatinib, Imatinib was developed in the late 1990s by biochemist Nicholas Lydon, a former researcher for Novartis, oncologist Brian Druker of Oregon Health and Science University (OHSU), and Charles Sawyers of Memorial Sloan-Kettering Cancer Center, who led the clinical trials confirming its efficacy in CML.

STI571 could inhibit c-Jun expression in K562 cells, but not in c-Jun-overexpression cells. (tmu.edu.tw)
Around the same time, and building on the observation that the vitamin folic acid could stimulate acute lymphoblastic leukemia (ALL) cells, Farber used folate analogs such as aminopterin and then amethopterin (methotrexate) to treat ALL, in what is often heralded as the first 'rational' drug development approach [ 4 ]. (biomedcentral.com)
The phases of Chronic Myeloid Leukemia are based on the number of immature white blood cells that are seen in the blood or bone marrow. (delveinsight.com)
Moreover, a shortage of normal white blood cells can increase a Chronic Myeloid Leukemia patient's risk of infection, and a shortage of platelets can lead to excessive bruising or bleeding. (delveinsight.com)
Symptoms may also occur because Chronic Myeloid Leukemia cells collect in organs such as the spleen. (delveinsight.com)
Polymerase chain reaction -based qualitative and quantitative tests detect and measure the BCR-ABL1RNA transcripts in leukemia cells taken from blood or bone marrow samples. (717698.com)
In laboratory experiments at Pennsylvania State University, researchers found that a component of Omega 3 known as Delta-12-J3 Prostaglandin or D12PGJ3 can selectively target the stem cells of chronic myelogenous leukemia or CML. (717698.com)
More types of chemotherapeutics are required to kill all cancerous cells as Leukemia is known to spread very rapidly throughout the whole body. (717698.com)
To identify regulators of primitive chronic myeloid leukemia (CML) cells, we performed a high-content cytokine screen using primary CD34 + CD38 low chronic phase CML cells. (haematologica.org)
Focusing on novel positive regulators of primitive CML cells, the myostatin antagonist myostatin propeptide gave the largest increase in cell expansion and was chosen for further studies. (haematologica.org)
In summary, we identify myostatin propeptide as a novel positive regulator of primitive CML cells and corresponding normal hematopoietic cells. (haematologica.org)
The major goals of my research are to identify how acute myeloid leukemia (AML) cells suppress the innate immune system and use this knowledge to develop new immunotherapies. (lu.se)
