Mn-Zn ferrite nanoparticles inducing ferroptosis to reverse the resistance in CML cells

Journal of Translational Medicine
Background Chronic myeloid leukemia (CML) is a malignant clonal disease of hematopoietic stem cells driven by the BCR-ABL fusion gene. Although tyrosine kinase inhibitors (TKIs) serve as targeted therapies, drug resistance remains one of the key ...

Tetrandrine overcomes drug resistance mediated by bone marrow microenvironment by regulating the expression of P-glycoprotein in acute leukemia

Hematology, 2022
Objectives: To study the effect of TET on the reversal of drug resistance in the bone marrow microenvironment, and to further promote the research on drug reversal.Methods: We established a co-culture system of bone marrow mesenchymal stem cells (BM-MSC)

Naturally Occurring Bicoumarin Compound Daphnoretin Inhibits Growth and Induces Megakaryocytic Differentiation in Human Chronic Myeloid Leukemia Cells

Cells, 2022
Daphnoretin extracted from the stem and roots of Wikstroemia indica (L.) C.A. Mey has been shown to possess antiviral and antitumor activities. Herein, we hypothesized that daphnoretin might induce megakaryocytic differentiation, thereby inhibiting the ...

Iron metabolism in K562 erythroleukemic cells.

Journal of Biological Chemistry, 1985
Iron delivery to K562 cells is enhanced by desferrioxamine through induction of transferrin receptors. Experiments were performed to further characterize this event with respect to iron metabolism and heme synthesis. In control cells, up to 85% of the iron taken up from iron-transferrin was incorporated into ferritin, 7% into heme, and the remainder ...

An Artificial Antibody‐Based Toolbox Accelerates Validation of Hidden Microproteins Encoded by the Dark Genome

Advanced Science, EarlyView.
Microproteins are hidden treasures encoded by the “dark proteome” but remain largely underexplored due to the lack of highly efficient tools. We developed a molecularly imprinted polymers (MIPs)‐based toolbox (CLAIMID) to achieve accelerated and ultrasensitive microproteins validation at multiple biological scales (single living cells, cell populations,

Trifolium Repens Blocks Proliferation in Chronic Myelogenous Leukemia via the BCR-ABL/STAT5 Pathway

Cells, 2020
Some species of clover are reported to have beneficial effects in human diseases. However, little is known about the activity of the forage plant Trifolium repens, or white clover, which has been recently found to exert a hepatoprotective action ...

Knocking-down cyclin A(2) by siRNA suppresses apoptosis and switches differentiation pathways in K562 cells upon administration with doxorubicin. [PDF]

PLoS ONE, 2009
Cyclin A(2) is critical for the initiation of DNA replication, transcription and cell cycle regulation. Cumulative evidences indicate that the deregulation of cyclin A(2) is tightly linked to the chromosomal instability, neoplastic transformation and ...

Hemoglobin Expression in Clones of K562 Cell Line [PDF]

European Journal of Biochemistry, 1982
The K562 cell line was cloned by dilution and the pattern of hemoglobin (Hb) production was analyzed in the clones thus obtained. The pattern of hemoglobin synthesis was different from one clone to another. According to the Hb phenotype the clones were classified in three main groups; group I no detectable Hb; group II Hb Portland; group III Hb ...

Different responses of normal cells (red blood cells) and cancer cells (K562 and K562/Dox cells) to low-dose ¹³⁷Cs gamma‑rays

Molecular and Clinical Oncology, 2021
High-dose radiation is deleterious to cells or tissues. However, the health risks of exposure to low-dose radiation remain unclear. The present study aimed to investigate the biological responses of low-dose gamma-ray in vitro exposure to normal red blood cells (RBCs) and erythroleukemia (K562 and K562/Dox) cancer cells.

Mapping Genetic Regulation of Transcription to Identify Functional Variants and Genes Associated with Pancreatic Cancer Risk

Advanced Science, EarlyView.
Integration of a pancreatic eQTL map with a GWAS meta‐analysis identifies 82 putative functional variants and 15 genes. The association between rs11102484 and pancreatic cancer risk is observed in a total of 5699 cases and 8467 controls. The G allele of rs11102484 weakens ZNF263 binding and the silencer‐promoter interaction, thereby increasing ST7L ...
