RETRACTED: DNA damage, homology-directed repair, and DNA methylation.
To explore the link between DNA damage and gene silencing, we induced a DNA double-strand break in the genome of Hela or mouse embryonic stem (ES) cells using I-SceI restriction endonuclease. The I-SceI site lies within one copy of two inactivated tandem

DNA Damage Repair and DNA Methylation in the Kidney [PDF]
The DNA repair system is essential for the maintenance of genome integrity and is mainly investigated in the areas of aging and cancer. The DNA repair system is strikingly cell-type specific, depending on the expression of DNA repair factors; therefore, different DNA repair systems may exist in each type of kidney cell.

Repurposing the Damage Repair Protein Methyl Guanine Methyl Transferase as a Ligand Inducible Fusion Degron [PDF]
We successfully repurpose the DNA repair protein methylguanine methyltransferase (MGMT) as an inducible degron for protein fusions. MGMT is a suicide protein that removes alkyl groups from the O6 position of guanine (O6G) and is thereafter quickly degraded by the ubiquitin proteasome pathway (UPP). Starting with MGMT pseudosubstrates (benzylguanine and

Repair of Methylation Damage in DNA and RNA by Mammalian AlkB Homologues [PDF]
Human and Escherichia coli derivatives of AlkB enzymes remove methyl groups from 1-methyladenine and 3-methylcytosine in nucleic acids via an oxidative mechanism that releases the methyl group as formaldehyde. In this report, we demonstrate that the mouse homologues of the alpha-ketoglutarate Fe(II) oxygen-dependent enzymes mAbh2 and Abh3 have ...

Decreased KAT5 Expression Impairs DNA Repair and Induces Altered DNA Methylation in Kidney Podocytes
Summary: Altered DNA methylation plays an important role in the onset and progression of kidney disease. However, little is known about how the changes arise in disease states.

Update on DNA methylation in UV radiation-related skin diseases
DNA methylation is a common epigenetic phenomenon that changes genetic expression without altering the DNA sequence. With deepening research on DNA methylation, more and more variable positions of methylation have been identified in a variety of diseases(

DNA Repair: Bioinformatics Helps Reverse Methylation Damage [PDF]
Recent work has uncovered a novel DNA repair enzyme: the AlkB protein of Escherichia coli, which oxidises the methyl groups of 1-methyladenine and 3-methylcytosine to hydroxymethyl moieties; the oxidised groups are subsequently released as formaldehyde, regenerating the unmodified bases.

PTEN Methylation by NSD2 Controls Cellular Sensitivity to DNA Damage [PDF]
Abstract The function of PTEN in the cytoplasm largely depends on its lipid-phosphatase activity, though which it antagonizes the PI3K–AKT oncogenic pathway. However, molecular mechanisms underlying the role of PTEN in the nucleus remain largely elusive.
