To support exciting, perhaps risky, innovative ideas in all areas of basic cancer research. The expectation is that this early-phase grant will enable the researcher to obtain enough preliminary results to apply for competitive external funding.
The tumor microenvironment affects the survival, development, and progression of cancer. Particularly, it is thought that the transfer of full length mRNA molecules between cancer and normal cells might profoundly affect the local microenvironment. We recently discovered a phenomenon by which full-length mRNAs can be transferred between cells.
Cancer cells tend to acidify their immediate microenvironment due to increased consumption of glucose at limiting oxygen conditions. These unique biophysical properties could be utilized to achieve differential recognition of antigens using the same therapeutic mAbs. Thus, incorporating pH-switchable recognition elements into therapeutic antibodies could result with the desired differential recognition. This would allow increasing the dose of the mAbs to maximize the therapeutic effect while reducing the severity of, or completely eliminate the off-target side effects.
