Colorectal cancer tumors both helped and hindered by T cells

Diabetes: Experimental drug may help restore insulin-producing cells
Researchers investigated whether they can reprogram pancreatic stem cell-like cells into insulin-producing beta-cells for potential diabetes treatment. They found that the genes that regulate insulin expression could be reactivated by using a drug previously investigated for treating patients with lymphomas and multiple myeloma. The research findings suggest a possible new treatment option for diabetes patients who rely on daily insulin injections.
