GENTLY mix by flicking the bottom of the tube with your finger a few times. SMARCB1 re-expression also modified BRG1 genomic occupancy with a loss mainly at the TSS (H4, Fig. This was further supported by separation of RMC cells into a stressed epithelial-like phenotype with higher levels of cytokines (IL8, LCN2), keratins and epithelial markers such as CDH1, CLDN1 and into RMC2 cells with higher expression of mesenchymal markers such as SFRP2, CDH2 and FN1. Overall, these results showed that SMARCB1 re-expression did not repress MYC genomic occupancy, but rather remodelled its binding profile in a manner suggesting that altered enhancer-promoter communications and loss of promoter-proximal BRG1 binding underlie reduced expression of the proliferation/oncogenic program. Pipette 950 l of room temperature SOC into the mixture. S9c), whereas only a minor change was seen at the TSS. Warm LB plates containing 100 g/ml ampicillin to 37C.
