Project description:Human Promyelocytic Leukemia Cell Line HL60 has been used extensively as a model for myeloid differentiation and leukemia. HL60-RG cell is its sub-line and shows a higher growth rate. In this study, we carried out a genome scan using SNP 10k mapping array on both cells. Comparative study on chromosomal changes of these cells will give us information on mechanism of tumor progression. Keywords: cell type comparison
Project description:The Fanconi anemia (FA) pathway is a network of proteins critical to the preservation of genomic integrity and the prevention of cancer. FA proteins safeguard the genome by regulating the cell cycle and facilitating error-free repair of DNA damage. Bi-allelic mutation of genes encoding FA pathway proteins causes the cancer predisposition syndrome Fanconi anemia (FA), which is associated with a high incidence of acute myeloid leukemia (AML). Individuals with mono-allelic mutation of a subset FA genes do not develop FA but suffer increased lifetime risk of solid and hematological malignancies. Within the general population, approximately 14% of sporadic AMLs harbor damaging mutations within the FA pathway. Our previous work demonstrated that inhibition of the mitotic kinase PLK1 induced synthetic lethality in cells deficient for FANCA, the gene most frequently lost in FA. This finding corroborates work from others that have identified synthetic lethal interactions between PLK1 and additional FA genes (FANCG, BRCA1, and BRCA2). Together, these findings suggest that FA pathway mutations may serve as biomarkers for sensitivity to PLK1 inhibitors, which have demonstrated therapeutic efficacy in an undefined subset of AML patients. Here, HL60 AML cells were generated with shControl or shFANCA and treated with 10nM volasertib for 24 h prior to kinome profiling.

Experiment Overall Design: Two samples HL60-NG cell and HL60-RG cel were analyzed by SNP 10k mapping array.
Project description:Expression data from untreated or Dll4-Fc treated THP1 cell line. We used Dll4-Fc stimulation of AML cells to study whether Notch activation has an impact on AML. We analyzed THP1 cell line in vitro treated with Dll4-Fc or vehicle control to determine genes affected by Notch activation.
Project description:We performed quantitative metabolomics and 13C-glucose isotopic profiling experiments on AML MOLM14 cell line following 24h of treatment with venetoclax (50 nM) and aracytine (25 uM) or combination compared to untreated samples. In addition, we also performed quantitative metabolomic experiments on MOLM14 silenced for BCL2 (shRNA).
Project description:Expression data from untreated or Dll4-Fc treated THP1 cell line. We used Dll4-Fc stimulation of AML cells to study whether Notch activation has an impact on AML. We analyzed THP1 cell line in vitro treated with Dll4-Fc or vehicle control to determine genes affected by Notch activation. THP1 cell line was cultured on plate coated with 30 nM Dll4-Fc or vehicle for 48 hours prior to RNA extraction and hybridization to Human Genome U133 Plus 2.0 Affymetrix arrays.
