Nucleolytic Cleavage of the Mixed Lineage Leukemia Breakpoint Cluster Region during Apoptosis [PDF]

open access: yesJournal of Biological Chemistry, 2001
VP-16 (etoposide) has recently been shown to induce topoisomerase II (TOP2)-mediated DNA cleavage within the mixed lineage leukemia (MLL) breakpoint cluster region (bcr), suggesting a role of TOP2 in MLL gene rearrangement. In our current studies, we have compared the induction of DNA cleavage within the MLL bcr in different cell lines after treatment ...

Extinctions of aculeate pollinators in Britain and the role of large-scale agricultural changes [PDF]

open access: yes, 2014
Pollinators are fundamental to maintaining both biodiversity and agricultural productivity, but habitat destruction, loss of flower resources, and increased use of pesticides are causing declines in their abundance and diversity. Using historical records

The clathrin-binding domain of CALM-AF10 alters the phenotype of myeloid neoplasms in mice. [PDF]

open access: yes, 2012
The PICALM (CALM) gene, whose product is involved in clathrin-mediated endocytosis, has been identified in two recurring chromosomal translocations, involving either MLL or MLLT10 (AF10). We developed a mouse model of CALM-AF10(+) leukemia to examine the

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

p185(BCR/ABL) has a lower sensitivity than p210(BCR/ABL) to the allosteric inhibitor GNF-2 in Philadelphia chromosome-positive acute lymphatic leukemia [PDF]

open access: yes, 2011
Background: The t(9;22) translocation leads to the formation of the chimeric breakpoint cluster region/c-abl oncogene 1 (BCR/ABL) fusion gene on der22, the Philadelphia chromosome.

Unraveling LINE‐1 retrotransposition in head and neck squamous cell carcinoma

open access: yesMolecular Oncology, EarlyView.
The novel RetroTest method allows the detection of L1 activation in clinical samples with low DNA input, providing global L1 activity and the identification of the L1 source element. We applied RetroTest to a real‐world cohort of HNSCC patients where we reported an early L1 activation, with more than 60% of T1 patients showing L1 activity.

Duplication of small segments within the major breakpoint cluster region in chronic myelogenous leukemia [PDF]

open access: yesBlood, 1993
Abstract The t(9;22) in chronic myelogenous leukemia (CML) may be reciprocal or, in a minority of cases, may result in an extensive deletion of a portion of the major breakpoint cluster region (M-bcr) of the BCR. This report provides evidence of the duplication of small segments within the M-bcr in a small group of patients with CML ...

High-Mass Proto-Stellar Candidates - II : Density structure from dust continuum and CS emission [PDF]

open access: yes, 2001
We present a detailed 1.2 mm continuum and CS spectral line study of a large sample of 69 massive star forming regions in very early stages of evolution, most of them prior to building up an ultracompact HII region.

Electric Pulse Regulated MXene Based Nanozymes for Integrative Bioelectricity Immuno‐Cancer Therapy

open access: yesAdvanced Functional Materials, EarlyView.
MXenzyme‐mediated bioelectricity cancer therapy (MXenzyme‐BECT) enhances cancer cell death through irreversible depolarization, ion channel disruption, ROS generation, and immunogenic cell death. Computational simulations reveal the electrical mechanisms by which MXenzyme acts on single cells and support to predict treatment parameters. Next‐generation

Rearrangement of the breakpoint cluster region in Philadelphia chromosome positive acute leukemia.

open access: yesActa medica Okayama, 1988
The rearrangement of breakpoint cluster region (ber) was examined in leukemic cells obtained from 3 patients initially diagnosed as having Ph+ acute leukemia, 2 with acute lymphocytic leukemia (ALL) and one with acute mixed leukemia. DNA was digested with Bgl II and BamH I. The ber rearrangement was present in the case of acute mixed leukemia (Case 1),
