A first principles study of wurtzite-structure MnO [PDF]

open access: yes, 2003
We present results of a density functional theory study of MnO in the wurtzite structure. Our motivation is provided by recent experiments reporting ferromagnetism in Mn-doped wurtzite structure ZnO.

Expression of MLL-AF4 or AF4-MLL fusions does not impact the efficiency of DNA damage repair

open access: yesOncotarget, 2016
The most frequent rearrangement of the human MLL gene fuses MLL to AF4 resulting in high-risk infant B-cell acute lymphoblastic leukemia (B-ALL). MLL fusions are also hallmark oncogenic events in secondary acute myeloid leukemia. They are a direct consequence of mis-repaired DNA double strand breaks (DNA-DSBs) due to defects in the DNA damage response ...

One-Loop Amplitudes in Supersymmetric QCD from MHV Vertices [PDF]

open access: yes, 2006
The Cachazo-Svrcek-Witten (CSW) rule for efficiently calculating gauge theory amplitudes is extended to N=1 supersymmetric QCD (SQCD), incorporating massless quarks, in a way preserving the manifest supersymmetry.

MLL-AF4 cooperates with PAF1 and FACT to drive high-density enhancer interactions in leukemia

open access: yesNature Communications, 2023
Aberrant enhancer activation is a key mechanism driving oncogene expression in many cancers. While much is known about the regulation of larger chromosome domains in eukaryotes, the details of enhancer-promoter interactions remain poorly understood ...

Comparative analysis of the biological characteristics and mechanisms of azole resistance of clinical Aspergillus fumigatus strains

open access: yesFrontiers in Microbiology, 2023
Aspergillus fumigatus is a common causative pathogen of aspergillosis. At present, triazole resistance of A. fumigatus poses an important challenge to human health globally. In this study, the biological characteristics and mechanisms of azole resistance

Functional Studies of MLL-AF4 and a Murinized pSer-variant thereof: MLL-AF4 Impairs the Ribosome Biosynthesis Pathway [PDF]

open access: yes, 2021
Abstract Background: Recent pathomolecular studies on the MLL-AF4 fusion protein revealed that the murinized version of MLL-AF4, the MLL-Af4 fusion protein, was able to induce leukemia when expressed in murine or human hematopoietic stem/progenitor cells (1).
