MITF maintains genome stability in nonmelanocyte lineages

open access: yesMolecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

open access: yesMolecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

PANoptosis in the pathogenesis of myelodysplastic syndromes

open access: yesMolecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Closing the gap on DNA ligase [PDF]

open access: yesStructure, 1996
The crystal structure of T7 DNA ligase complexed with ATP illuminates the mechanism of covalent catalysis by a superfamily of nucleotidyl transferases that includes the ATP-dependent polynucleotide ligases and the GTP-dependent mRNA capping enzymes.

Castration‐resistant prostate cancer cells are addicted to the high activity of cyclin‐dependent kinase 2

open access: yesMolecular Oncology, EarlyView.
We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

T4 DNA ligase synthesizes dinucleoside polyphosphates [PDF]

open access: yes, 1998
T4 DNA ligase (EC 6.5.1.1), one of the most widely used enzymes in genetic engineering, transfers AMP from the E-AMP complex to tripolyphosphate, ADP, ATP, GTP or dATP producing p4A, Ap3A, Ap4A, Ap4G and Ap4dA, respectively.

DNA ligase I from Xenopus laevis eggs.

open access: yes, 1991
International audienceWe have purified the major DNA ligase from Xenopus laevis eggs and raised antibodies against it. Estimates from SDS PAGE indicate that this DNA ligase is a 180 kDa protein.

"Cullin 4 makes its mark on chromatin"

open access: yesCell Division, 2006
Cullin 4 (Cul4), a member of the evolutionally conserved cullin protein family, serves as a scaffold to assemble multisubunit ubiquitin E3 ligase complexes.

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer

open access: yesMolecular Oncology, EarlyView.
Cancer cells' high translational demand creates opportunities to therapeutically target ribosome function. Ribosome stalling and collisions activate ZAKα and the ribotoxic stress response (RSR), which can trigger rapid, p53‐independent apoptosis in cancer.
