| Title |
HMGA1 and FOXM1 synergistically regulate a common gene network modulating angiogenesis in breast cancer |
| Organism |
Homo sapiens |
| Experiment type |
Expression profiling by high throughput sequencing
|
| Summary |
One of the factors involved in TNBC aggressiveness is HMGA1, a member of non-histone chromatin proteins. The High mobility group A1 is an architectural transcription factor which, by altering chromatin structure and interacting with transcription factors, can regulate the transcription of several genes. HMGA1 protein is defined as an oncofetal protein as it is highly expressed during the embryogenesis while its expression decreases or is absent in adults, and it is re-expressed in a variety of tumors, including breast cancer. Several works established that, in breast cancer, HMGA1 expression is correlated with high tumor grade and tumor metastasis, resistance to therapies and poor prognosis. The goal of this project is to find out in details, which are the genes that are modulated by HMGA1 in MDA-MB-231 triple negative breast cancer cell line model.

| Overall design |
In order to identify the HMGA1-molecular partners involved in developing TNBC aggressiveness, we performed RNA sequencing analysis (RNA-Seq), on the MDA-MB-231 triple-negative cell line at 24 and 72 hours after HMGA1 silencing, looking for transcription factors as putative upstream regulators of HMGA1-gene networks.
