	Tissue-specific and developmental regulation of camptothecin and 10-hydroxycamptothecin levels in Camptotheca acuminata
		Camptotheca acuminata seeds were obtained from Jintang (30.72° N, 104.61° E), Sichuan Province, China in January 2002.
		Camptotheca acuminata has CPT in all organs throughout its life cycle (Lin et al., 1977; Liu and Adams, 1996) but produces little HCPT except in cotyledon and embryonal axis of 9-15 day old seedlings (Lopez-Meyer et al., 1994).

		Camptothecin - a monoterpenoid indole alkaloid derived from the Chinese tree Camptotheca acuminata Decne - and its derivatives are unique in their ability to inhibit DNA topoisomerase.
		This is achieved by stabilizing a covalent reaction intermediate, termed as the “cleavable complex” which ultimately causes tumor cell death.

		The Lab of MDidea Group is currently one of the international leaders in the development and clinical (human) studies of a new family of anticancer drugs, the camptothecins, which have been in clinical trials since 1997.
		More than 30 years ago it was found that extracts from a Chinese tree, Camptotheca Acuminata, had potent anticancer activity against a mouse leukemia.
		The active substance, designated Camptothecin, was tried clinically on incurable patients in the early 1970's by physicians at the National Cancer Institute in Washington D.C. It was found to have some anticancer activity, but was too toxic as administered in those days to be of practical use.

		Previously, the only species known was Camptotheca acuminata which is a tree native to China.
		Prior to the research conducted at SFA, the extraction of CPT’s from the Camptotheca tree was a very long and arduous process.
		Making CPT production even more difficult, C. acuminata has been listed as a national endangered species in China, and the fruits, as well as the export of related products, are under regulation by the Chinese government.

		The Camptotheca genome, however, contained a single TSB gene, which must respond to demands from both primary and secondary metabolism.
		In Arabidopsis, TSB and all other enzymes of the tryptophan biosynthetic pathway have been localized to chloroplasts, but in Camptotheca, there appeared to be little expression in tissues where the predominant plastids are photosynthetically competent chloroplasts.
		Despite the fact that all metabolically active cells require tryptophan, the single gene encoding TSB in Camptotheca is not a uniformly expressed housekeeping gene.

	Camptotheca acuminata
		Camptotheca acuminata is a member of the family Nyssaceae (tupelo family) and is native only to China and Tibet, where it is known as xi shu ("happy tree").
		Its primary anti-cancer ingredient is a quinoline alkaloid called camptothecin, which in turn has been modified to create a host of other anti-cancer drugs, including irinotecan, topotecan, 9-aminocamptothecin, and CPT-11.
		In 1966, after Wall joined the Research Triangle Institute, he and other researchers isolated camptothecin.

		Sustained Harvest of Camptothecin from the Leaves of Camptotheca acuminata
		Over a 12-week period, new growth was collected at different intervals from Camptotheca acuminata trees to determine whether a leaf harvest strategy would be an efficient means for the production of the alkaloid camptothecin.
		Because camptothecin accumulates in young leaves and because the harvesting of young tissue stimulates axillary bud outgrowth, this strategy increased the harvestable amount of camptothecin from trees in a nondestructive manner.
