Abstract:
The main aim of this study was to evaluate the effect of space-like environment on the chemopreventive activity of Brassica sprouts against thyroid cancer cells in vitro. For this purpose the sprouts of broccoli, kale, kohlrabi, and Brussels sprouts were cultivated in darkness and in microgravity for 5-7 days. Then, the sprouts' extracts were examined for cytotoxic and antiproliferative activity against thyroid cancer and normal cells. The tested microgravity environment stimulated the cytotoxic activity of kohlrabi sprouts, causing approximately 50% reduction in thyroid cancer cells' viability, while at the same time increasing the viability of normal thyroid cells. Broccoli sprouts showed the strongest antiproliferative activity against normal thyroid cells, with the best effect visible for darkness conditions, which may contribute to the reduction of thyroid hyperplasia. Microgravity and darkness significantly enhanced the antiproliferative activity of kale, especially in 7-day-old sprouts (inhibition approximately 90%). The tested conditions also increased the antiproliferative activity of kohlrabi sprouts, but in the case of Brussels sprouts the effect was unfavorable. The study showed that microgravity and darkness conditions may have significant influence on the chemopreventive role of Brassica sprouts against thyroid cancer cells in vitro, especially in the case of broccoli and kohlrabi sprouts.
Insights
Space-like conditions enhance the cancer-fighting properties of Brassica sprouts. Kohlrabi sprouts showed significant cytotoxic effects on thyroid cancer cells, while broccoli sprouts protected normal thyroid cells.
Area of Science:
- Oncology
- Plant Science
- Space Biology
Background:
- Brassica sprouts possess known chemopreventive properties.
- Investigating the impact of extreme environments on bioactive compounds is crucial for novel therapeutic development.
Purpose of the Study:
- To assess the influence of a space-like environment (microgravity and darkness) on the chemopreventive potential of Brassica sprouts against thyroid cancer cells.
- To evaluate the cytotoxic and antiproliferative effects of Brassica sprout extracts on both cancerous and normal thyroid cells in vitro.
Main Methods:
- Cultivation of broccoli, kale, kohlrabi, and Brussels sprouts under simulated microgravity and darkness for 5-7 days.
- Preparation of sprout extracts and assessment of their cytotoxic and antiproliferative activities using in vitro assays against thyroid cancer and normal thyroid cell lines.
Main Results:
- Microgravity stimulated kohlrabi sprout extract to reduce thyroid cancer cell viability by ~50% while sparing normal cells.
- Broccoli sprout extracts exhibited potent antiproliferative effects on normal thyroid cells, particularly under darkness, suggesting a role in preventing thyroid hyperplasia.
- Kale sprout extracts showed significantly enhanced antiproliferative activity under microgravity and darkness, with 7-day-old sprouts achieving ~90% inhibition.
- Kohlrabi sprout extracts also demonstrated increased antiproliferative activity, whereas Brussels sprout extracts showed unfavorable effects.
Conclusions:
- Microgravity and darkness conditions can significantly modulate the chemopreventive efficacy of Brassica sprouts against thyroid cancer cells in vitro.
- Broccoli and kohlrabi sprouts show particular promise for developing space-derived cancer chemoprevention strategies.
- Further research into optimizing cultivation conditions in space could unlock new avenues for cancer therapeutics.
