This work utilizes single cell RNA sequencing to identify transcriptional populations and gene changes for the purpose of immune-related cancer therapies. First we have characterized the T cell populations of the normal and malignant human pancreas. Furthermore, we utilized single cell TCR sequencing to track transcriptional states of T cell clones from human PDACs into a T cell culture product for adoptive cell therapy. Second, we examined the potential role of radiotherapy in inducing an immune response in hormone receptor positive breast tumors.

Integrin-Mediated Mechanotransduction Controls Activation Of Yap And Invasive Growth Of Breast Cancer, Xiaobo Wang

Tumor extracellular matrix (ECM) stiffness is correlated with the aggressiveness of breast cancer. Integrin-mediated adhesion and signaling are crucial for mammary tumorigenesis and tumor progression, in which focal adhesion kinase (FAK) - Src family kinases (SFKs) serves as a hub to relay the mechanical cues from the ECM. We have investigated the mechanisms through which integrin signaling controls mammary tumorigenesis and found that integrin-mediated mechanotransduction controls invasive growth of breast cancer cells in stiff matrices through activation of FAK and YAP. Mechanistic studies revealed that integrin signaling induces - via activation SFKs - tyrosine phosphorylation and inactivation of LATS1 and …
