Un medicament împotriva diabetului reconfigurează celulele tumorale.

Recent research led by scientists at Umeå University in Sweden suggests that pioglitazone, a common diabetes medication, may offer unexpected benefits in the fight against prostate cancer. This revelation stems from observations made during the monitoring of patients with both prostate cancer and diabetes, who were treated with medications targeting the PPARγ protein. Notably, these patients did not experience recurrences of cancer during follow-up, according to findings reported by ScitechDaily.

The study conducted was retrospective, encompassing 69 patients diagnosed with prostate cancer and type 2 diabetes, who were followed between 2014 and 2023 at the Medical University of Innsbruck. Complementary to the patient data, the researchers conducted laboratory tests on cellular cultures and experiments with mice to further investigate the impact of pioglitazone.

Key findings from the research indicate that pioglitazone not only slowed the growth of prostate cancer cells but also altered their metabolism in a way that hindered their survival and spread. The medication appears to reprogram cancer cells by activating the PPARγ receptor, which is recognized for its role in regulating metabolism and insulin sensitivity.

Professor Lukas Kenner, one of the primary authors of the study, highlighted this breakthrough, stating, “For the first time, we have clinical observations showing that patients with prostate cancer and diabetes who were treated with medications targeting this protein did not experience recurrences.”

However, the researchers caution that further clinical studies are necessary to determine the potential effectiveness of pioglitazone in patients with prostate cancer who do not have diabetes. This calls for a broader inquiry into its therapeutic applications beyond the current patient population, to understand whether it could benefit a wider array of patients affected by prostate cancer.

The implications of these findings could reshape treatment strategies for prostate cancer, especially among those also battling diabetes. However, until more comprehensive studies are carried out, pioglitazone should not be regarded as a standard treatment for prostate cancer. The ongoing research will be crucial in establishing clearer guidelines and understanding the full extent of pioglitazone’s potential role in oncology.
