Anaplastic thyroid cancer (ATC) lacks iodide uptake ability due to MAPK activation increasing the expression of the histone methyltransferase EZH2, which represses thyroid differentiation genes (TDGs) such as the sodium iodide symporter (NIS). Dual inhibition of MAPK (U0126) and EZH2 (EPZ6438/Tazemetostat) reverses this mechanism, thus restoring TDG ...

Specialized interfaces of Smc5/6 control hinge stability and DNA association
Structural Maintenance of Chromosomes (SMC) complexes maintain genome integrity by regulating the segregation of chromosomes. Here, Altet al. describe the structure of the heterodimeric Smc5/6-hinge from fission yeast and define functional features ...

Isolation of human and murine hematopoietic stem cells for DNA damage and DNA repair assays
Summary: Hematopoietic stem and progenitor cells (HSPCs) reside in the bone marrow and supply blood cells. Efficient methods for isolation of HSPCs are required. Here, we present protocols for the isolation of human and murine HSPCs using manual and FACS-

Common Mitochondrial DNA Mutations Generated through DNA-Mediated Charge Transport [PDF]
Mutation sites that arise in human mitochondrial DNA as a result of oxidation by a rhodium photooxidant have been identified. HeLa cells were incubated with [Rh(phi)2bpy]Cl3 (phi is 9,10-phenanthrenequinone diimine), an intercalating photooxidant, to ...

Hematopoietic (stem) cells—The elixir of life?
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Bioinformatic approaches to the investigation of the atavistic genes implicated in cancer
Introduction: Cancer is a widespread phenomenon occurring across multicellular organisms and represents a condition of atavism, wherein cells follow a path of reverse evolution that unlocks a toolkit of ancient pre-existing adaptations by disturbing hub ...

CAS9 is a genome mutator by directly disrupting DNA-PK dependent DNA repair pathway. [PDF]
With its high efficiency for site-specific genome editing and easy manipulation, the clustered regularly interspaced short palindromic repeats (CRISPR)/ CRISPR associated protein 9 (CAS9) system has become the most widely used gene editing technology in ...

TGF-β signaling links E-cadherin loss to suppression of nucleotide excision repair. [PDF]
E-cadherin is a cell adhesion molecule best known for its function in suppressing tumor progression and metastasis. Here we show that E-cadherin promotes nucleotide excision repair through positively regulating the expression of xeroderma pigmentosum ...
