The presence of a brain tumor can be determined by identifying a crucial membrane protein in the urine, according to research from Nagoya University in Japan. By eliminating the need for intrusive tests and raising the possibility that tumors are found early enough for surgery, their protein may be used to identify brain cancer. The results of this study may also have implications for the early detection of other cancers.The findings of the research were published in ACS Nano.Although early detection of many types of cancer has contributed to the recent increases in cancer survival rates, the survival rate for brain tumors has remained almost unchanged for over 20 years. Partly this is due to their late detection. Physicians often discover brain tumors only after the onset of neurological symptoms, such as loss of movement or speech, by which time the tumor has reached a considerable size. Detecting the tumor when it is still small, and starting treatment as soon as possible, should help to save lives.One possible sign that a person has a brain tumor is the presence of tumor-related extracellular vesicles (EVs) in their urine. EVs are nano-sized vesicles involved in a variety of functions, including cell-to-cell communication. Because those found in brain cancer patients have specific types of RNA and membrane proteins, they could be used to detect the presence of cancer and its progression.Although they are excreted far from the brain, many EVs from cancer cells exist stably and are excreted in the urine without breaking down. Urine testing has many advantages, explains Associate Professor Takao Yasui of Nagoya University Graduate School of Engineering. "Liquid biopsy can be performed using many body fluids, but blood tests are invasive," he said. "Urine tests are an effective, simple, and non-invasive method because the urine contains many informative biomolecules that can be traced back to identify the disease."A research group led by Yasui and Professor Yoshinobu Baba of Nagoya University's Graduate School of Engineering, in collaboration with Nagoya University's Institute of Innovation for Future Society and the University of Tokyo, has developed a new analysis platform for brain tumor EVs using nanowires at the bottom of a well plate. Using this device, they identified two specific types of EV membrane proteins, known as CD31/CD63, from urine samples of brain tumor patients. Looking for these tell-tale proteins could enable doctors to identify tumor patients before they develop symptoms."Currently, EV isolation and detection methods require more than two instruments and an assay to isolate and then detect EVs," said Yasui. "The all-in-one nanowire assay can isolate and detect EVs using one simple procedure. In the future, users can run samples through our assay and change the detection part, by selectively modifying it to detect specific membrane proteins or miRNAs inside EVs to detect other types of cancer. Using this platform, we expect to advance the analysis of the expression levels of specific membrane proteins in patients' urinary EVs, which will enable the early detection of different types of cancer."( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
