Abstract: Provided herein are methods for determining the chance of a tumor not responding to an anti-cancer therapy (e.g., a T cell-based immunotherapy) based on the presence, density, number, and/or location of certain three-cell structures as described herein. The three-cell structures may comprise a T cell, an immunosuppressive tumor-associated macrophage, and an immunosuppressive regulatory T cell. Such methods may be useful for identifying patients not likely to respond to T cell-based immunotherapy. Also provided herein are methods for determining the prognosis and/or invasiveness of a tumor. The present disclosure also encompasses methods for treating a tumor, as well as kits for performing the methods disclosed herein.

Abstract: Compounds and compositions are presented that inhibit K-ras, and especially mutant K-ras. Certain compounds preferentially or even selectively inhibit specific forms of mutant K-Ras, and particularly the G12D mutant form.
