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.

BCR::ABL1‐Induced Enhancer Reprogramming Uncovers Hypersensitivity of Ph+B‐ALL Cells to Enhancer‐Targeting Drugs

Advanced Science, EarlyView.
Ng et al. show that the BCR::ABL1 kinase that drives the lymphoid leukemia Ph+B‐ALL modulates enhancer function by coopting signaling‐inducible transcription factors such as MYC, STAT5, and ETV5. BCR::ABL1 thereby promotes the transcriptional program driving and defining this leukemia and renders Ph+B‐ALL cells hypersensitive to enhancer‐inhibiting ...

NanoLoop: A Deep Learning Framework Leveraging Nanopore Sequencing for Chromatin Loop Prediction

Advanced Science, EarlyView.
Chromatin loops are central to gene regulation and 3D genome organization. Leveraging Nanopore sequencing's ability to jointly capture DNA sequence and methylation, we present NanoLoop, the first framework for genome‐wide chromatin loop prediction using Nanopore data.

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.

Dynamic Decoration of DNA Scaffolds for High‐Resolution Cancer Cell Subtyping

Advanced Science, EarlyView.
This study presents a dual‐mode imaging platform that utilizes self‐assembly and disassembly of DNA scaffolds for high‐resolution cancer cell detection. The structural rigidity of DNA scaffolds effectively prevents cellular internalization for over 300 min.

Effects of annexin A1 on apoptosis and cell cycle arrest in human leukemic cell lines

Acta Pharmaceutica, 2019
Recent studies suggest that annexin A1 (ANXA1) promotes apoptosis in cancerous cells. This study aims to investigate the effects of ANXA1 on apoptosis and cell cycle arrest in K562, Jurkat and U937 cells and peripheral blood mononu-clear cells (PBMC ...

Genome-Wide CRISPR Screen Reveals Cancer Cell Resistance to NK Cells Induced by NK-Derived IFN-γ

Frontiers in Immunology, 2019
The anti-leukemia activity of NK cells helps prevent relapse during hematopoietic stem cell transplantation (HSCT) in leukemia patients. However, the factors that determine the sensitivity or resistance of leukemia cells in the context of NK-mediated ...

Humanized and Charge‐Optimized CSPG4‐Specific CAR‐T Cells show Enhanced Efficacy against Head and Neck Squamous Cell Carcinoma

Advanced Science, EarlyView.
CSPG4 is identified as a high‐value, stemness‐associated target in HPV‐negative HNSCC. By implementing rational biophysical engineering, a humanized and charge‐optimized CAR is developed to overcome tonic signaling‐induced exhaustion. This strategy induces a profound transcriptomic shift toward a rejuvenated, stem‐like memory state, significantly ...

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 ...

Affinity Peptides With pH Sensitivity for the Enrichment of CD38+ Cells

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The selective enrichment of cell populations based on surface markers is critical for the advancement of gene and cell therapies. Current antibody‐based cell isolation methods, such as fluorescence‐ and magnetic‐activated cell sorting (FACS and MACS), offer high specificity but are limited by scalability, cost, and potential adverse effects on
