Researchers representing the Wellcome Sanger Institute (The University of Cambridge) and MRC Cancer Unit demonstrated the role of steroidogenesis and T-Cells using transgenic steroidogenesis-reporter mouse line while fighting a tumor. Tumour signals T-Cells to produce steroids resulting in declined antitumor immunity.

When gene responsible for immunosuppressive steroids biosynthesis i.e., cyp11a1  were removed or switched off using a drug aminoglutethimide, there was a gradual slow down in tumor growth.

Researchers said that some preliminary data shows a similar response of human tissue against tumor formation and further research is needed to confirm it. And if it gets confirmed, it would pave a way towards the treatment of cancer by targeting the steroidogenesis pathway to prevent antitumor immunosuppression and will save human lives.
