Two studies on gastrointestinal stroma tumors describe advances that may lead to new treatments

Gastrointestinal stroma tumors (GIST) are cancers that start in specialized nerve cells found in the digestive system, from the esophagus and stomach to the intestines and rectum.

Study pinpoints an enzyme with a significant impact on SARS-CoV-2 replication

By applying a systems biology approach, a recent bioRxiv* preprint research paper by scientists from the Icahn School of Medicine at Mount Sinai in New York unveils interactions between the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) and p38 mitogen-activated protein kinase (MAPK) pathway responsible for regulating the expression of crucial inflammatory mediators in human lung epithelial cells.

Study identifies the cause and treatment for rare rheumatoid-like autoinflammatory condition

The absence of a protein that activates the body's antiviral defenses can cause a rare rheumatoid-like autoinflammatory condition that is treatable with an FDA-approved class of drugs known as TNF (tumor necrosis factor) inhibitors, a global research team led by Mount Sinai has found.

Arteriolar niche used by breast cancer cells to prepare for metastasis

More than 43,000 American women will die from breast cancer this year. Most of those deaths will occur after the cancer has spread to other organs, a process called metastasis. This involves at least five major steps.

Using self-assembled drugs to achieve a breakthrough in cancer therapy

One of the most challenging aspects of cancer treatment is the huge variety of different tumors that can occur with each one potentially requiring a different solution because unfortunately, one drug does not fit all.

SARS-CoV-2 Spike may trigger production of antibodies that cross-react with human thrombopoietin to induce thrombocytopenia

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infected individuals often suffer from thrombocytopenia, a condition associated with low platelet counts. The cytokine thrombopoietin regulates platelet count. Previous studies have reported that thrombocytopenia can increase the coronavirus disease 2019 (COVID-19) mortality rate by about five times.
