Oncogene Proteins

The promoter-associated noncoding RNA PNCCCND1_B assembles a protein–RNA complex to regulate cyclin D1 transcription in Ewing sarcoma

Most Ewing sarcomas are characterized by the in-frame chromosomal translocation t(11;22) generating the EWS–FLI1 oncogene. EWS–FLI1 protein interacts with the RNA helicase DHX9 and affects transcription and processing of genes involved in neoplastic transformation, including CCND1 (the cyclin D1 gene), which contributes to cell-cycle dysregulation in cancer.

Minimal residual disease (MRD) in non-Hodgkin lymphomas: Interlaboratory reproducibility on marrow samples with very low levels of disease within the FIL (Fondazione Italiana Linfomi) MRD Network

In 2009, the four laboratories of the Fondazione Italiana Linfomi (FIL) minimal residual disease (MRD) Network started a collaborative effort to harmonize and standardize their methodologies at the national level, performing quality control (QC) rounds for follicular lymphoma (FL) and mantle cell lymphoma (MCL) MRD assessment.
