Mechanism of KIT gene regulation by GATA1 lacking the N-terminal domain in Down syndrome–related myeloid disorders

Scientific Reports, 2022
Children with Down syndrome (DS) are at high risk of transient abnormal myelopoiesis (TAM) and myeloid leukemia of DS (ML-DS). GATA1 mutations are detected in almost all TAM and ML-DS samples, with exclusive expression of short GATA1 protein (GATA1s ...

Occurrence and a possible mechanism of penetration of natural killer cells into k562 target cells during the cytotoxic interaction [PDF]

, 1995
The cytotoxic interaction between cloned human Natural Killer (NK) cells and K562 target cells was studied using confocal laser scanning microscopy (CLSM) and conventional fluorescence microscopy.

Differences of basic and induced autophagic activity between K562 and K562/ADM cells

Intractable & Rare Diseases Research, 2017
Patients with acute myeloid leukemia (AML) often have a poor prognosis due to drug resistance, which is regarded as a tough problem during the period of clinical therapeutics. It has been reported that autophagy, an important event in various cellular processes, plays a crucial role in mediating drug-resistance to cancer cells.

Comparative analyses of CTCF and BORIS occupancies uncover two distinct classes of CTCF binding genomic regions. [PDF]

, 2015
BackgroundCTCF and BORIS (CTCFL), two paralogous mammalian proteins sharing nearly identical DNA binding domains, are thought to function in a mutually exclusive manner in DNA binding and transcriptional regulation.ResultsHere we show that these two ...

Comparative proteomic analysis of differentially expressed proteins between K562 and K562/ADM cells

Chinese Medical Journal, 2008
Multidrug resistance to chemotherapeutic agents is an important clinical problem during the treatment of leukemia. The resistance process is multifactorial. To realize the total factors involved in multidrug resistance, we analyzed the differentially expressed proteins of K562 and K562/ADM cells and we investigated one of the up-regulated proteins ...

MRE11 facilitates the removal of human topoisomerase II complexes from genomic DNA [PDF]

, 2012
Topoisomerase II creates a double-strand break intermediate with topoisomerase covalently coupled to the DNA via a 5'-phosphotyrosyl bond. These intermediate complexes can become cytotoxic protein-DNA adducts and DSB repair at these lesions requires ...
