Tonic signaling of the B‐cell antigen‐specific receptor is a common functional hallmark in chronic lymphocytic leukemia cell phosphoproteomes at early disease stages

open access: yesMolecular Oncology, EarlyView.
B‐cell chronic lymphocytic leukemia (B‐CLL) and monoclonal B‐cell lymphocytosis (MBL) show altered proteomes and phosphoproteomes, analyzed using mass spectrometry, protein microarrays, and western blotting. Identifying 2970 proteins and 316 phosphoproteins, including 55 novel phosphopeptides, we reveal BCR and NF‐kβ/STAT3 signaling in disease ...

Determination of ADP/ATP translocase isoform ratios in malignancy and cellular senescence

open access: yesMolecular Oncology, EarlyView.
The individual functions of three isoforms exchanging ADP and ATP (ADP/ATP translocases; ANTs) on the mitochondrial membrane remain unclear. We developed a method for quantitatively differentiating highly similar human ANT1, ANT2, and ANT3 using parallel reaction monitoring. This method allowed us to assess changes in translocase levels during cellular

Supercoiled circular DNA-protein complex in Escherichia coli: purification and induced conversion to an opern circular DNA form.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1969
The 23S twisted circular form of ColE(1) DNA has been isolated from Escherichia coli as a tightly associated DNA-protein complex with a sedimentation coefficient of approximately 24S.

Evaluation of KRAS and NRAS mutations in metastatic colorectal cancer: an 8‐year study of 10 754 patients in Turkey

open access: yesMolecular Oncology, EarlyView.
This nationwide study evaluated KRAS and NRAS mutations in 10 754 Turkish patients with metastatic colorectal cancer. The results revealed a mutation frequency of 51.1%, with 46.6% having KRAS mutations, 4.5% having NRAS mutations, and 48.5% being wild‐type for both.

Vegetative λ DNA: III. Pulse-labeled Components [PDF]

open access: yes, 1968
The structures of λ DNA labeled during short pulses of [^3H]thymine at various times after infection have been studied by ultracentrifugal analysis. Circular DNA's, both the supercoiled form and an open form, are the main DNA components synthesized in ...

Optical Identification of a DNA-Wrapped Carbon Nanotube: Signs of Helically Broken Symmetry

open access: yes, 2008
High intrinsic mobility and small, biologically-compatible size make single-walled carbon nanotubes (SWNTs) in demand for the next generation of electronic devices.

Programmed pH-Driven Reversible Association and Dissociation of Interconnected Circular DNA Dimer Nanostructures.

open access: yesNano letters (Print), 2016
The switchable pH-driven reversible assembly and dissociation of interlocked circular DNA dimers is presented. The circular DNA dimers are interconnected by pH-responsive nucleic acid bridges. In one configuration, the two-ring nanostructure is separated

Systematic profiling of cancer‐fibroblast interactions reveals drug combinations in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Fibroblasts, cells in the tumor environment, support ovarian cancer cell growth and alter morphology and drug response. We used fibroblast and cancer cell co‐culture models to test 528 drugs and discovered new drugs for combination treatment. We showed that adding Vorinostat or Birinapant to standard chemotherapy may improve drug response, suggesting ...

Effects of Circular DNA Length on Transfection Efficiency by Electroporation into HeLa Cells

open access: yesPLoS ONE, 2016
The ability to produce extremely small and circular supercoiled vectors has opened new territory for improving non-viral gene therapy vectors. In this work, we compared transfection of supercoiled DNA vectors ranging from 383 to 4,548 bp, each encoding ...
