Tokyo: Scientists have used a new tool to identify a key membrane protein in urine that can tell if a patient has a brain tumour. Membrane proteins are proteins that either constitute biomembranes or are capable of associating with or crossing these biomembranes. A protein used to detect brain cancer could reduce the need for invasive tests to find tumors and increase the chances of detecting tumors at an early stage so that they can be removed surgically, according to a study.

The study, from Japan’s Nagoya University, could have potential implications for the detection of other types of cancer, the study said. This study has been published in the journal ‘ACS Nano’. In recent times, due to the early detection of many types of cancer, the chances of survival of cancer patients have increased. However, there has been no change in the survival rate of people with brain tumors over the past 20 years.
This could potentially be due to late detection. According to the study, a possible indication of a person suffering from brain tumor is the presence of tumor-related extracellular vesicles (EV) in their urine. It states that EVs are micro-sized cells that are involved in a number of functions, including cell-to-cell communication. Since these EVs, found in patients with brain cancer, contain specific types of RNA and membrane proteins, they can be used for cancer detection. (agency)
