In the past decades, a number of genomic changes were found in colorectal adenoma and carcinoma, but the target genes are limited and molecular mechanism of adenoma to carcinoma progression is still unknown.
Such genomic changes are not found in MMTV-ErbB2 mice, suggesting that the ErbB2 model, developed using the endogenous ErbB2 promoter, is more representative of human ErbB2-amplified breast tumors in this regard [ 30, 35].
Indeed, the modest number of changes to polyploid gene expression corresponded to the limited number of genomic changes that were previously found to accompany polyploidization in cotton [ 56].
When CGH results were analyzed for each MIN-O line, we found recurring genomic changes that were specific to certain lines.
High-throughput methods were also used to investigate the genomic mutation of cultured ADMSCs and BMMSCs, whereas, these studies failed to find significant genomic changes and stated that MSCs expanded in vitro confirmed an overall stability of genomic profile.
We did not find significant genomic changes associated with ROS (e.g., changes in the expression of sod, gst) with MeHg exposure (these genes were on the macroarray) at these levels of MeHg.
These genomic changes are cryptic, but are always found within the Enterobacteriaceae flexible genome.
In spite of the long transmission time and many carriers of the cluster SMI-049 strain in the community, the IS6110 RFLP pattern has stayed virtually unchanged and we found extremely few genomic changes (4 SNPs and one small deletion) between the three sequenced isolates that were isolated 9 years apart.
In breast carcinoma, the total number of genomic changes, as determined by cytogenetics, was found to be almost two times higher in tumors with BRCA1 mutation than in control group [ 24].
Also the karyotypically (based on G-banding) normal hESC lines were also found to have several genomic changes that involved genes with known roles in cancer.
