Acute tissue injury activates satellite cells and promotes sarcoma formation via the HGF/c-MET signaling pathway

Some patients with soft tissue sarcoma (STS) report a history of injury at the site of their tumor. While this phenomenon is widely reported, there are relatively few experimental systems that have directly assessed the role of injury in sarcoma format...

Injury Promotes Sarcoma Formation

Some patients with soft-tissue sarcoma (STS) report a history of injury at the site of their tumor. Although this phenomenon is widely reported, there are relatively few experimental systems that have directly assessed the role of injury in sarcoma fo...

PD-1/SHP-2 inhibit Tc1/Th1 phenotypic responses and the activation of T cells in the tumor microenvironment

Immune rejection of tumors is mediated by IFN-γ production and T cell cytolytic activity. These processes are impeded by PD-1, a co-inhibitory molecule expressed on T cells that is elevated in tumor-infiltrating lymphocytes (TIL). PD-1 elevation may r...

Host miR155 Promotes Tumor Growth

miR155 is a regulator of immune cell development and function that is generally thought to be immunostimulatory. However, we report here that genetic ablation of miR155 renders mice resistant to chemical carcinogenesis and the growth of several transp...

Host miR-155 promotes tumor growth through a myeloid-derived suppressor cell-dependent mechanism

miR-155 is a regulator of immune cell development and function that is generally thought to be immunostimulatory. However, we report here that genetic ablation of miR-155 renders mice resistant to chemical carcinogenesis and the growth of several trans...
