Project description:Breast and ovarian cancer susceptibility genes, BRCA1 and PALB2 have enigmatic roles in cellular growth and mammalian development. While these genes are essential for growth during early developmental programs, inactivation later in adulthood leads to increased growth and formation of tumors, leading to their designation as tumor suppressors. We performed genome-wide analysis assessing their chromatin residence and gene expression responsiveness using high throughput sequencing in breast epithelial cells. These experiments revealed a critical role for BRCA1 and PALB2 in transcriptional responsiveness to NF-kB, a crucial mediator of growth and inflammatory response during development and cancer. Importantly, we also uncovered a vital role for these proteins in response to retinoic acid (RA), a growth inhibitory signal in breast cancer cells, which may constitute the basis for their tumor suppressor activity. MCF-7 cells were infected with PALB2, BRCA1, p65/RelA and non targeting (SCR) shRNAs. After puromycin selection, cells were stimulated with 10ng/ml TNF-alpha 1 hour

Comparison of the genome wide profiles of the BRCA protein complex (BRCA1 and PALB2) and phosphorylated RNAPII (P-Ser2) in MCF10A cells by ChIP-seq. Effect of BRCA1 and PALB2 knockdown (shRNAs) on transcription was assessed by RNA-seq.

Project description:The BRCA1 tumor suppressor gene encodes a multi-domain protein for which several functions have been described. These include a key role in homologous recombination repair (HRR) of DNA double-strand breaks (DSBs), which is shared with two other high-risk hereditary breast cancer suppressors, BRCA2 and PALB2. Although both BRCA1 and BRCA2 interact with PALB2, BRCA1 missense variants affecting its PALB2-interacting coiled-coil domain are considered sequence variants of uncertain clinical significance (VUS). Using genetically engineered mice, we now show that a BRCA1 coiled-coil domain VUS, Brca1 p.L1363P, disrupting the interaction with PALB2 leads to embryonic lethality and loss of breast cancer suppression. Brca1 p.L1363P mammary tumors develop with a similar latency as Brca1-null tumors, but show different histopathological features and more stable DNA copy number profiles. Nevertheless, Brca1 p.L1363P mammary tumors are HRR-incompetent and responsive to cisplatin and PARP inhibition.
