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.

Sensing and Reprogramming Surface Receptor Activation With Synthetic Transcriptional Circuits

Advanced Science, EarlyView.
A synthetic receptor‐signalling induced transcription (RESIT) circuit is designed based on receptor activation mediated split protease complementation and release of membrane‐tethered synthetic transcriptional modules. The RESIT system enables probing Ca2+ entry, receptor tyrosine kinase (RTK) activities and Ras activation, and reprogramming RTK ...

Effects of P-Glycoprotein and Its Inhibitors on Apoptosis in K562 Cells

Molecules, 2014
P-glycoprotein (P-gp) is a major factor in multidrug resistance (MDR) which is a serious obstacle in chemotherapy. P-gp has also been implicated in causing apoptosis of tumor cells, which was shown to be another important mechanism of MDR recently.

Systematic comparison of monoclonal versus polyclonal antibodies for mapping histone modifications by ChIP-seq. [PDF]

, 2016
BackgroundThe robustness of ChIP-seq datasets is highly dependent upon the antibodies used. Currently, polyclonal antibodies are the standard despite several limitations: They are non-renewable, vary in performance between lots and need to be validated ...

Autophagy enhanced antitumor effect in K562 and K562/ADM cells using realgar transforming solution

Biomedicine & Pharmacotherapy, 2018
Realgar transforming solution (RTS) can be produced from a biotransformation process by using microorganisms cultured with realgar in our lab. RTS has been demonstrated as a novel arsenic anti-leukemia agent in K562 and K562/ADM. However, its underlying mechanism is unclear.

Reprogramming Antitumor Immunity: NK Cell Strategies to Navigate the Immunosuppressive Tumor Microenvironment

Advanced Science, EarlyView.
ABSTRACT Tumor immune escape is a major barrier to durable cancer immunotherapy, as advanced malignancies create a tumor microenvironment (TME) that preferentially exhausts and disables T cell responses. While most approved cell therapies are T cell‐based, this limitation motivates the exploration of an alternative effector cell platform.

Discovery of a Potent Fluorescence Polarization Probe for Identifying USP1 Allosteric Inhibitors

Advanced Science, EarlyView.
This study presents the first ubiquitin‐specific protease 1 (USP1) allosteric fluoroprobe and fluorescence polarization assay, enabling the differentiation of allosteric and catalytic site inhibitors. Further, a novel class of tetrahydroisoquinoline‐based USP1 inhibitors is designed, with compound 14a (USP1 IC50 = 29.9 nM) showing strong selectivity ...

CRISPR-Cas9 screens in human cells and primary neurons identify modifiers of C9ORF72 dipeptide-repeat-protein toxicity. [PDF]

, 2018
Hexanucleotide-repeat expansions in the C9ORF72 gene are the most common cause of amyotrophic lateral sclerosis and frontotemporal dementia (c9ALS/FTD).

A Robust Deep Temporal Causal Discovery Platform for Single‐Cell Gene Regulatory Network Reconstruction

Advanced Intelligent Discovery, EarlyView.
scTIGER2.0 is a deep‐learning framework that infers gene regulatory networks from single‐cell RNA sequencing data. By integrating correlation, pseudotime ordering, deep learning and bootstrap‐based significance testing, it reduces false positives and reveals directional gene interactions.
