Towards precise classification of cancers based on robust gene functional expression profiles

...t year at an ACS national meeting, the researchers reported they were able to prevent diabetes in a group of mice by using a synthetic compound called ISO-1 to block the MIF protein. If human studies prove the effectiveness of ISO-1, the compound or its derivatives could ultimately save lives, reduce health c...
