Project description:M6 cells expression a similar genetic signature as the parent tumor, C3(1)Tag tumor. The mammary tumors, and tumor cell line, are distinct from normal mammary epithelial tissue (FVB) BRCA/p53, cmyc, h2n, p53ERneg, p53ERpos, pymt and ras samples were not reported in this paper. We used microarrays to determine whether the M6 cell line retains the SV40Tag signature (91 gene signature) that is expressed in C3(1)Tag tumors but not FVB normal mammary tissue.

Project description:Silencing HoxA1 in vivo by intraductal delivery of nanoparticle-formulated siRNA reduced mammary tumor incidence by 75% , reduced cell proliferation, and prevented loss of ER and PR expression. 8 week wild type FVB mouse whole mammary gland and 8week to 20 week transgenic FVB C3(1)-SV40Tag mouse whole mammary gland
Project description:We report the role of EMT in promtoing a trailblazer state in C3-TAg tumors. We extracted whole RNA for sequencing from C3-TAg tumors (invasive) and tumor derived noninvasive clonal cell lines. Data was aligned to GRCm38.
Project description:We report the role of TGFi1 in promoting EMT in C3-TAg tumor derived organoid line. We extracted whole RNA for sequencing from C3-TAg derived org-line organoids treated with TGFi1 for different time points. Data was aligned to GRCm38.
Project description:We performed CITE-seq (10x Genomics-based) to profile and compare the transcriptomes and cell surface expression of immune epitopes in the primary breast tumors of transgenic mice (C3-1-TAg) with or without MCT chemotherapy. We sequenced a total of six different tumor samples. We created an antibody pool consisting of 35 different antibodies and stained each sample individually with this antibody pool. Then, we stained each sample with it's own unique hashing antibody so that we could subsequently pool the samples for loading onto the 10x Chromium and later prepare one library consisting of all sight samples and finally separate each sample in silico by it's unique hashing antibody. The samples are as follows: (1) HTO1: tumor of PBS treated C3-1-TAg mouse; (2) HTO2: tumor of PBS treated C3-1-TAg mouse; (3) HTO3: tumor of PBS treated C3-1-TAg mouse; (4) HTO4: tumor of MCT treated C3-1-TAg mouse; (5) HTO5: tumor of MCT treated C3-1-TAg mouse; (6) HTO6: tumor of MCT treated C3-1-TAg mouse. The following sample comparisons were made: HTO1, HTO2, and HTO3 versus HTO4, HTO5, and HTO6.
Project description:We report the role of TGFI and EGFR signaling in inducing a trailblazer state in C3-TAg tumor derived organoid line. We extracted whole RNA for sequencing from C3-TAg organoids treated with a combination of growth factors and receptor inhibitor. Data was aligned to GRCm38.
