Researchers at Thomas Jefferson University developed an animal model of chronic lymphocytic leukemia (CLL), a disease characterized by uncontrolled proliferation of white blood cells. The model enables scientists to investigate biochemical and molecular mechanisms underlying the disease and test potential new drugs.
Researchers found that mitoxantrone induction therapy significantly reduced disease activity in MS patients, with a 76% relapse-free rate at one year and 64% at four years. The annual relapse rate decreased by nearly 90% following treatment.
Researchers identified a genetic anomaly in mice resistant to the ecotropic murine leukemia virus, a major cancer-causing virus. By analyzing proteins, they found a defective protein that blocks viral entry, potentially leading to new gene therapies for humans.
Researchers are using spatial statistics to analyze cases of renal failure and leukemia in Texas. They found that the distribution of renal failure cases is consistent with random phenomena, but may have underlying hotspots for cancer cases.
Researchers developed a Herceptin-DM1 conjugate that targets HER2-positive breast cancer and shows complete regression in mice. Additionally, a new Bcr-Abl inhibitor called PD173955 demonstrates greater potency than Gleevec against leukemia cells, providing new hope for treatment-resistant cancers.
Researchers found that brief cycles of high-dose chemotherapy produced long-term disease-free survival in more than half of adults treated for Burkitt's small non-cleaved lymphoma and leukemia. The regimen achieved an 80% complete response rate, with 52% of patients remaining in continuous remission after five years.
A study published in JCI Journals reveals that an excess of healthy cells may hold leukemia in check. The researchers found that these healthy cells could be used as a therapeutic target to develop new treatments for the disease.
Researchers have found that leukemia cells resist apoptosis due to constitutive activation of STAT3 and/or STAT1. AG-490, a JAK inhibitor, promotes apoptosis in these cells by blocking STAT3 function.
Researchers at UCSD Cancer Center develop a two-drug combination that tricks leukemia-causing gene Bcr-Abl into committing suicide, achieving complete eradication of CML cells. The treatment uses STI571 and Leptomycin B to mobilize and trap the oncogene in the nucleus.
Researchers found that 10 out of 20 bioflavonoids tested caused breaks in the MLL gene, which is a key player in about 80% of infant leukemias. The study suggests that high dietary intake of bioflavonoids could cause DNA damage and potentially trigger leukemia.
A study using polymerase chain reaction detects MRD in long-term CML survivors, finding that approximately 25% of patients had evidence of disease at some time after transplant. The team aims to identify patients who appear cured but may still harbor disease and benefit from early therapeutic intervention.
Researchers at the University of Toronto found a strong association between magnetic field exposures in residences and the risk of developing childhood leukemia. Children exposed to higher levels of magnetic fields were two to four times more likely to develop leukemia, with risks highest for those diagnosed before age six.

Researchers at St. Jude Children's Research Hospital have discovered a novel leukemia-producing transcription factor called E2A-HLF, which transforms immature lymphocytes by preventing normal destruction programs. This finding provides a potential window into understanding leukemias that result from altered survival signals.
Researchers identify a molecular 'safety key' that normally regulates cell growth, and discovering how it can be disrupted to trigger cancer. The team found a protein called Abi-2 that fits into the normal enzyme cABL, keeping it turned off, and proposes a new way to treat cancers by targeting this molecular pathway.
