miRNA expression during early, mid and late breast cancer disease progression in mammary glands from MMTV-PyMT transgenic mice

Project description:MicroRNAs (miRNAs) are small noncoding RNAs that typically inhibit the translation and stability of messenger RNAs (mRNAs), controlling genes involved in a variety of cellular processes. miRNA dysregulation is recognized to play an essential role in the development and progression of cancer. MMTV-PyMT mice (Jax Strain: FVB/N-Tg(MMTV-PyVT)634Mul/J) are a well-characterized transgenic mouse model of breast cancer. Upon activation of the MMTV-PyVT transgene (mouse mammary tumor virus (MMTV) long terminal repeat upstream of a cDNA sequence encoding the Polyoma Virus middle T antigen (PyVT)) female carriers develop palpable mammary tumors as early as 5 weeks of age. We performed miRNA microarrays on samples from the MMTV-PyMT transgenic mouse model to investigate the differential expression of miRNAs during development of malignant disease in this model.

PyMT 4 stages tumor progression microRNA sequencing

Project description:We sequenced mammary gland samples of MMTV-PyMT mouse from 4 stages (hyperplasia at week 6, adenoma/MIN at week 8, early carcinoma at week 10, and late carcinoma with lung metastasis at week 12) during tumor progression. We sacrificed 3 PyMT (FVB background) mice and 3 FVB control mice at each of the 4 stages, extracted small RNA and performed sequencing.

Transcriptome changes of endothelial cells in mouse breast tumors by STING activation II

Project description:In order to identify transciptomic changes of endothelial cells (Ecs) in response to STING activation, endothelial cells were soted using FACS and RNA-seq was performed. We compared ECs from 3 models; normal mammary fat pad, MMTV-PyMT spontaneous breast tumor, implanted breast tumor. Tumor cells derived from MMTV-PyMT spontaneous breast tumor were expanded on culture and implanted in mammary fat pad of female FVB mice to establish implanted breast tumor model.
