Project description:Metastatic lesions are typically not found until patients self-report symptoms or they become radiologically evident. We have developed an engineered metastatic niche (scaffold) that recruits aggressive tumor cells prior to their colonization in other organs. The engineered niche can be monitored for dynamic gene expression, and changes at this site are analogous to those in a native metastatic site (lung) for triple negative breast cancer (4T1 cells). We were able to develop a 10-gene signature from the scaffold that accurately monitors disease progression and recurrence or resistance to resection therapy. This data set acts to dissect the heterogeneity of the cell populations in the engineered and native metastatic niche and identify the cell types that contribute to the success of the signature.

RNA-seq of murine macrophages (J774A.1 and Raw264.7) grown for 48 hours in conditioned media collected from primary murine Triple Negative Breast Cancer cells

Project description:The goal of the experiment was to demonstrate if the overexpression of human-Prune-1 in Triple Negative breast cancer cells induces M2-polarization of macrophages in vitro. For this purpose, murine primary cells from breast tumor developed by Genetically Engineered Mouse Models (GEMMs) of TNBC (i.e., MMTV-Wnt1) and metastatic TNBC overexpressing both human Prune-1 and Wnt1 in mammary gland (i.e., MMTV-Prune-1/Wnt1) were obtained. Conditioned media were collected from these primary cells (1x106 cells) after 24 hours. Murine macrophages (J774A.1 and Raw264.7; 1x106) were starved for six hours and then grown for 48 hours in those conditioned media collected from MMTV-Wnt1 and MMTV-Prune-1/Wnt1 cells. Untreated macrophages were used as negative control for the experiment.
