Houstonia (plant) fruit is an often roughly cordate capsule enclosing many seeds and which usually dehisces via a suture across its apex. "Houstonia" consists of 20 species native to North America. Another 5 species are classified in the genus "Stenaria"; "Houstonia" without "Stenaria" is paraphyletic. Close relatives of the genus are "Oldenlandia microtheca" and, more distantly, "Arcytophyllum". Its members superficially resembles species of the genus "Myosotis" (Forget-me-nots), but are distinguished from the latter by having only 4 sepals (petals) instead of 5. Species accepted as of May 2014 are: Houstonia (plant) Houstonia (bluet) is a genus of plants in the family Rubiaceae.
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.
