Expansion of Human NK Cells Using K562 Cells Expressing OX40 Ligand and Short Exposure to IL-21

Frontiers in Immunology, 2019
Background: Natural Killer (NK) cell-based immunotherapy used to treat cancer requires the adoptive transfer of a large number of activated NK cells. Here, we report a new effective method to expand human NK cells ex vivo using K562 cells genetically ...

Mitigation of off-target toxicity in CRISPR-Cas9 screens for essential non-coding elements. [PDF]

, 2019
Pooled CRISPR-Cas9 screens are a powerful method for functionally characterizing regulatory elements in the non-coding genome, but off-target effects in these experiments have not been systematically evaluated.

METTL3 regulates WTAP protein homeostasis [PDF]

, 2018
The Wilms tumor 1 (WT1)-associated protein (WTAP) is upregulated in many tumors, including, acute myeloid leukemia (AML), where it plays an oncogenic role by interacting with different proteins involved in RNA processing and cell proliferation.

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 ...

TAM family kinases are potential candidate targets for therapeutic intervention in chronic myeloid leukemia

Discover Oncology
Background Chronic Myeloid Leukemia (CML) is a hematologic disorder depicted by BCR::ABL1 translocation; a constitutively active tyrosine kinase (TK) and a hallmark of CML. Kinase domain mutations and the activation of alternative signaling pathways lead

Changes in the expression of miR-381 and miR-495 are inversely associated with the expression of the MDR1 gene and development of multi-drug resistance.

PLoS ONE, 2013
Multidrug resistance (MDR) frequently develops in cancer patients exposed to chemotherapeutic agents and is usually brought about by over-expression of P-glycoprotein (P-gp) which acts as a drug efflux pump to reduce the intracellular concentration of ...

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 ...

PYRROLO[1,2-b][1,2,5]BENZOTHIADIAZEPINES (PBTDs) induce apoptosis in K562 cells

BMC Cancer, 2007
Background The objective of this study was to gain insight into the molecular mechanism of induced cell death (apoptosis) by PYRROLO [1,2-b][1,2,5]BENZOTHIADIAZEPINES (PBTDs) series compounds, using human (K562) cells as a model.
