Houstonia (plant) Houstonia (plant) Houstonia (bluet) is a genus of plants in the family Rubiaceae. Many species were formerly classified, along with other genera since segregated elsewhere, in a more inclusive genus "Hedyotis". Bluets are often small and delicate. For example, "H. rosea" may grow only one inch tall. Some species are single stemmed and others have multiple stems in bunches. Flowers are blue, purple, lavender, white, or rose, often with shades of one color present in an individual population. Flowers have 4 sepals, colloquially denominated "petals", a salverform corolla with 4 lobes, and an inferior ovary. Some species exhibit heterostyly. The
Cruciferous vegetables to isothiocyanates (ITCs) by the action of myrosinase. ITCs, possibly a bioactive component in cruciferous vegetables, are being investigated for their chemopreventive and chemotherapeutic effects. As one example in laboratory research, ITCs such as phenethyl isothiocyanate reduced levels of the oncoprotein MCL1. Other in vitro research indicates ITCs may affect levels of the BCR-ABL fusion protein, the oncoprotein affecting mechanisms of leukemia. Chemicals contained in cruciferous vegetables induce the expression of the liver enzyme CYP1A2. Furthermore, some drugs such as haloperidol and theophylline are metabolized by CYP1A2. Consequently, consumption of cruciferous vegetables may decrease bioavailability and half-life of these drugs.
