The mechanisms of long-term survival of occult breast cancer cells in the bone marrow microenvironment are not known. Using selected bone marrow stromal components with demonstrated roles in promoting growth arrest and survival of breast cancer cells, we reconstituted an in vitro model for dormancy of breast cancer cells in bone marrow.

Auxiliary factors likely play an important role in determining the polyadenylation efficiency of mammalian pre-mRNAs. We previously identified an auxiliary factor, hnRNP H/H', which stimulates 3'-end processing through an interaction with sequences downstream of the core elements of the SV40 late polyadenylation signal.

The nucleotide sequence of the region located transcriptionally upstream of the K99 fimbrial subunit gene (fanC) was determined. Several putative transcription signals and two open reading frames, designated fanA and fanB, became apparent. Frameshift mutations in fanA and fanB reduced K99 fimbriae expression 8-fold and 16-fold, respectively. Complementation(More)
A patient with crhonic lymphatic leukaemia (CLL) is presented who was first seen with a basal cell carcinoma and subsequently developed two further malignant conditions within a year, without receiving any treatment for his leukaemia. It is suggested that this leukaemia was a predisposing factor in the development of his carcinomas.
