Researchers identify mechanism of immune suppression in ovarian cancer

Weill Cornell Medicine researchers have discovered a mechanism that ovarian tumors use to cripple immune cells and impede their attack—blocking the energy supply T cells depend on. The study, published Oct. 23 in Nature, points toward a promising new immunotherapy approach for ovarian cancer, which is notoriously aggressive and hard to treat.

Harnessing the power of miRNA for cancer diagnosis and treatment

This study is led by Dr. Shiwei Duan (Department of Clinical Medicine, School of Medicine, Hangzhou City University, Hangzhou, Zhejiang, China). His team analyzed literature on miRNA, summarizing the close relationship between these small molecules and cancer. miRNA is a type of non-coding RNA that does not encode proteins, but can target more than 60% of human protein-coding genes.

Scientists overcome major challenge in gene therapy and drug delivery

Imagine trying to poke a hole in the yolk of a raw egg without breaking the egg white. It sounds impossible, but researchers at the University of California San Diego have developed a technology that performs a similarly delicate task in living cells. They created an array of nanopillars that can breach the nucleus of a cell - the compartment that houses our DNA - without damaging the cell's outer membrane.
