TranscriptomicsDissecting the signalling pathways underlying cellular senescence
Cellular senescence is a program of irreversible cell cycle arrest that normal cells undergo in response to progressive shortening of telomeres, changes in telomeric structure, oncogene activation or oxidative stress. The underlying signalling pathways, potentially of major clinicopathological rele...

TranscriptomicsPrim_Fibs
To determine changes in gene expression in primary fibroblasts undergoing replicative senescence, a direct comparison between early passage proliferating cells and senescent cells was performed. Frozen stocks of the primary fibroblasts (HMF3) from which the lines HMF3A and HMF3Dwt were derived (O'Ha...

TranscriptomicsHMF3A_with_3Dwt
HMF3A cells, created from adult human mammary fibroblasts by immortalisation with a thermolabile SV40 large T antigen and the catalytic sub-unit of human telomerase, undergo co-ordinated induction of cellular senescence upon inactivation of T antigen. HMF3A cells cease proliferating by 4 days at 39Â...

HMF3A cells, created from adult human mammary fibroblasts by immortalisation with a thermolabile SV40 large T antigen and the catalytic sub-unit of human telomerase, undergo co-ordinated induction of cellular senescence upon inactivation of T antigen.

TranscriptomicsA novel unusual chromosome 11 abnormality: a homozygous somatic deletion of the entire WT1 gene within a heterozygous 11p13 deletion and UPD limited to 11p15 in a Wilms tumor and establishment of an immortalized cell line
We describe a stromal predominant Wilms tumor with a complex, tumor specific chromosome 11 aberration: a homozygous deletion of the entire WT1 gene within a heterozygous 11p13 deletion and an additional region of uniparental disomy (UPD) limited to 11p15.5-p15.2 including the IGF2 gene. The tumor ca...

TranscriptomicsThe effect of Ras on the signalling networks in senescence
Activated Ha-ras was introduced to HMF3A cells. HMF3A cells are conditionally immortalised human mammary fibroblasts. They undergo co-ordinated senescence upon inactivation of LT antigen, when cultured at 39C. The introduction of Ras did not prevent this but affected the molecular profile. Keywords ...

TranscriptomicsDiff_cell_shift
Immortalised lines created from different cell types from the human breast were induced to undergo senesecence by inactivation of the immortalising LT antigen.

HMF3A cells, created from adult human mammary fibroblasts by immortalisation with a thermolabile SV40 large T antigen and the catalytic sub-unit of human telomerase, undergo co-ordinated induction of cellular senescence upon inactivation of T antigen. Given the importance of p53, we sought to determ...

TranscriptomicsTranscription profiling of immortalised human mammary luminal epithelial cells and variants expressing a moderate and high level of ERBB2
To investigate changes in gene expression associated with ERBB2, expression profiling of immortalised human mammary luminal epithelial cells and variants expressing a moderate and high level of ERBB2 has been carried out using cDNA microarrays corresponding to approximately 6,000 unique genes/ESTs. ...
