Calreticulin mutations help diagnose occult myeloproliferative neoplasms in patients with splanchnic vein thrombosis

Myeloproliferative neoplasms (Fildadelfia chromosome-negative) are the most common cause of splanchnic vein thrombosis, but they are often masked. A study led by IDIBAPS has found that screening for mutations in the gene encoding calreticulin (CALR) increases the number of diagnoses of this type of cancer and may reduce the need for additional studies, such as bone marrow biopsy, in some patients. This is the first study to evaluate the frequency of these mutations in a large number of patients.

A mutation in progenitor cells identified as origin and therapeutic target for cholangiocarcinoma

In recent years, cancer research has been focused on the identification of mutations in genes involved in tumor development. Nevertheless, the molecular pathways that contribute to the progression of the disease remain quite unknown. The journal Nature publishes a paper in which an international team of scientists, led by Nabeel Bardesy, PhD, from the Harvard Medical School, suggests that a mutation in the IDH enzyme (isocitrate dehydrogenase), that occurs in liver progenitor cells, promotes the progression of cholangiocarcinoma, a type of liver cancer. Josep M. Llovet, MD, PhD, ICREA Research Professor at the HCC Translational Research Lab of the Liver Unit at IDIBAPS and Director of Mount Sinai Liver Cancer Program at the Icahn School of Medicine at Mount Sinai (New York) has collaborated in the study together with Daniela Sia, PhD, and Helena Cornellà, members of the same research group.
