Dissecting the Kaiso binding profile in clear renal cancer cells.

Background: There has been a notable increase in interest in the transcriptional regulator Kaiso, which has been linked to the regulation of clonal hematopoiesis, myelodysplastic syndrome, and tumorigenesis. Nevertheless, there are no consistent data on the binding sites of Kaiso in vivo in the genome. Previous ChIP-seq analyses for Kaiso contradicted the accumulated data of Kaiso binding sites obtained in vitro.

Comparative Analysis of Genome Editors Efficiency on a Model of Mice Zygotes Microinjection.

Genome editing is an indispensable tool for functional genomics. The caveat of the genome-editing pipeline is a prevalence of error-prone non-homologous end joining over homologous recombination, while only the latter is suitable to introduce particularly desired genetic variants. To overcome this problem, a toolbox of genome engineering was appended by a variety of improved instruments.

An IDH-independent mechanism of DNA hypermethylation upon VHL inactivation in cancer.

Hypermethylation of tumour suppressors and other aberrations of DNA methylation in tumours play a significant role in cancer progression. DNA methylation can be affected by various environmental conditions, including hypoxia. The response to hypoxia is mainly achieved through activation of the transcriptional program associated with HIF1A transcription factor.

Kaiso Regulates DNA Methylation Homeostasis.

Gain and loss of DNA methylation in cells is a dynamic process that tends to achieve an equilibrium. Many factors are involved in maintaining the balance between DNA methylation and demethylation. Previously, it was shown that methyl-DNA protein Kaiso may attract NCoR, SMRT repressive complexes affecting histone modifications.
