General description
Induction of differentiation is a therapeutic approach for cancer. Treatment of leukemias with differentiation-inducing factors in combination with pro-apoptotic compounds has been shown to be highly effective . Ectopic expression of the transcription factor C/EBPa causes reprogramming of leukemia cells, resulting in expression of a normal cell phenotype.
The BLaER1 cell line is a tamoxifen-inducible derivative of the RCH-ACV B-cell leukemia cell line genetically modified using a retrovirus vector to express C/EBPa fused with the estrogen receptor hormone binding domain (ER) and GFP . A study demonstrated that BLaER1 cells could efficiently convert into cells exhibiting increased adherent, phagocytic and quiescent properties with a transcriptome resembling normal macrophages . Cells retained their phenotype even when C/EBPa was inactivated, a characteristic of genuine cell reprogramming. C/EBPa induction also impaired cell tumorigenicity after transplantation into immunodeficient mice. BLaER1 is thus a model for highly efficient transdifferentiation of B-cell-derived human cancer cells.
Source:
BLaER1 cells are a single subclone isolated from C/EBPaER-GFP-transfected RCH-ACV acute lymphoblastic leukemia (ALL) cells sorted for GFP expression. The parental cell line was obtained from the bone marrow of a female with chromosome translocation 1;19 and trisomy 8 .
Biosafety Level 2:
BLaER1 cells contain squirrel monkey retrovirus (SMRV) and should be handled under biosafety level 2.

Successful treatment of acute promyelocytic leukemia (APL) has identified several novel approaches to induce leukemic cell differentiation and selective apoptosis by overcoming the site-specific transcriptional repression by dominant fusion leukemogenic proteins characteristic of APL and other forms of acute myelogenous

Pyroptosis is a mechanism of programmed, necrotic cell death mediated by gasdermins, a family of pore-forming proteins. Caspase-1 activates gasdermin D (GSDMD) under inflammatory conditions, whereas caspase-3 activates GSDME under apoptotic conditions, such as those induced by chemotherapy. These pathways

A cell line (RCH-ACV) was established from a bone marrow sample of a child with acute lymphoblastic leukemia (ALL). The cell line lacked Epstein-Barr virus nuclear antigen and exhibited a recently described nonrandom chromosome translocation, 1;19, thought to be associated

Earlier work demonstrated that the transcription factor C/EBPα can convert immature and mature murine B lineage cells into functional macrophages. Testing >20 human lymphoma and leukemia B cell lines, we found that most can be transdifferentiated at least partially into
