Here we demonstrate for the first time evidence of lineage switch from B-1 B lymphocyte to a macrophage , or so-called transdifferentiation, occurring in mature cells in vivo. Specifically, using transgenic B6.Mb1-iCre/Rosa26-YFP mice, in which YFP expression is restricted exclusively to B cell line...

The canine transmissible veneral tumour (CTVT) is one of the few known clonally transmissible cancers in nature. CTVT regresses spontaneously or after a single treatment with vincristine, however we know little of the mechanisms. To understand CTVT regression, we performed methylome analyses on seri...

To identify differentially expressed human and viral miRNAs across a panel of B-cell lines, including several primary effusion lymphomas (PEL). Gammaherpesvirus and host cell microRNAs (miRNAs) together modulate gene expression in normal and malignant cells. Using microRNA microarrays, we determined...

1) To identify changes in gene expression upon over-expression of hsa-miR-221 in JSC1 cells. 2) To identify human miRNA targets expressed in a panel of B-cell lines. Gammaherpesvirus and host cell microRNAs (miRNAs) together modulate gene expression in normal and malignant cells. Using microRNA micr...

Cyclin D1 belongs to the core cell cycle machinery1, and it is frequently overexpressed in human cancers2. The full repertoire of cyclin D1 functions in normal development and in cancer cells is currently unknown. To address this question, here we introduce a novel approach that allows one to deter...

We examined the transcriptional function of cyclin D1 in mouse development using two approaches. First, we queried association of cyclin D1 with the genome of E14.5 mouse embryos using ChIP-on-chip approach. We observed binding of cyclin D1 to several promoter regions. Second, we compared gene exp...
