Experimental Treatment Directly Kills Prostate Tumor Cells While Reawakening Antitumor Immunity

Prostate-targeted, engineered nanoparticles made of amorphous silica are effective in killing prostate tumors directly while enhancing anti-tumor immunity, according to a preclinical study led by investigators at Weill Cornell Medicine and the Cornell Duffield College of Engineering. The particles, derived from silicon dioxide, a common component of healthy foods or fossilized sedimentary structures from single-celled organisms, induced several complete remissions of aggressive tumors in mouse models, supporting the further investigation of their use in clinical trials.

Weill Cornell Medicine Scientist Receives Award for Research on New Ovarian Cancer Targets

Dr. Dan Landau, the Bibliowicz Family Professor of Medicine, and a member of the Sandra and Edward Meyer Cancer Center and the Englander Institute for Precision Medicine at Weill Cornell Medicine, has received a Lotus Award from the Pershing Square Foundation for research aimed at uncovering new immunotherapy targets in ovarian cancer.

The Pershing Square Foundation supports ambitious cancer research projects, and since 2025 has been funding ovarian cancer research with three-year grants of $750,000, now called Lotus Awards. Awardees were selected for their scientific rigor, originality and potential to drive meaningful advances in a disease where progress is urgently needed. Dr. Landau is one of eight recipients this year.

“We’re grateful for this opportunity to develop new therapeutic perspectives to benefit patients with this deadly but relatively under-studied form of cancer,” said Dr. Landau, who is also a core faculty member of the New York Genome Center.

Metal-Free Carbon Monoxide Prodrugs May Help Prevent Cancer’s Deadly Spread

A carefully designed metal-free carbon monoxide prodrug—an inactive compound that is converted into its active form in the body—may help prevent some of the deadliest forms of cancer from spreading, according to researchers at Weill Cornell Medicine. The recent preclinical study, published in Advanced Science, offers a new strategy to potentially reduce the recurrence of pancreatic and triple-negative breast cancer in patients who initially respond to treatment.

Even after surgery and chemotherapy, microscopic cancer cells may survive and later establish new tumors in distant organs. Researchers have long pursued treatments that can safely block this process.
