    Timed release of turmeric stops cancer cell growth in osteosarcoma

    Written by Hina Zahid Published On 2019-06-21T19:28:39+05:30  |  Updated On 19 Aug 2021 5:20 PM IST

    The researchers at the School of Mechanical and Materials Engineering, Washington State University have developed a drug delivery system using curcumin, the main ingredient in the spice turmeric, that successfully inhibits bone cancer cells while promoting the growth of healthy bone cells. The research could come handy for better post-operative treatments for people with osteosarcoma, the second most prevalent cause of cancer death in children.


    The research has been published in the journal, ACS Applied Materials and Interfaces.

    Turmeric has been used in cooking and as medicine for centuries in Asian countries, and its active ingredient, curcumin has been shown to have anti-oxidant, anti-inflammatory and bone-building capabilities. It has also been shown to prevent various forms of cancers.

    Young patients with bone cancer are often treated with high doses of chemotherapy before and after surgery, many of which have harmful side effects. Researchers would like to develop gentler treatment options, especially after surgery when patients are trying to recover from bone damage at the same time that they are taking harsh drugs to suppress tumour growth.

    "I want people to know the beneficial effects of these natural compounds," said Bose. "Natural biomolecules derived from these plant-based products are inexpensive and a safer alternative to synthetic drugs."


    However, when taken orally as medicine, the compound can't be absorbed well in the body. It is metabolized and eliminated too quickly.


    In their study, the researchers used 3D printing to build support scaffolds out of calcium phosphate. While most implants are currently made of metal, such as ceramic scaffolds, which are more like real bone, could someday be used as a graft material after bone cancer surgery. The researchers incorporated curcumin, encapsulated in a vesicle of fat molecules into the scaffolds, allowing for the gradual release of the chemical.


    The researchers found that their system inhibited the growth of osteosarcoma cells by 96 per cent after 11 days as compared to untreated samples. The system also promoted healthy bone cell growth.


    "This study introduces a new era of integration - where modern 3d printing technology is coupled with the safe and effective use of alternative medicine, which may provide a better tool for bone tissue engineering," said Bose.
