Chinese cabbage Chinese cabbage Chinese cabbage ("Brassica rapa", subspecies "pekinensis" and "chinensis") can refer to two groups of Chinese leaf vegetables often used in Chinese cuisine: the Pekinensis Group (napa cabbage) and the Chinensis Group (bok choy). These vegetables are both variant cultivars or subspecies of the turnip and belong to the same genus as such Western staples as cabbage, broccoli, and cauliflower. Both have many variations in name, spelling, and scientific classification, especially bok choy cultivars. The Chinese cabbage was principally grown in the Yangtze River Delta region, but the Ming Dynasty naturalist Li Shizhen popularized it by bringing attention to
BOK (gene) Bcl-2 protein family. The mouse homologue of Bok is called Matador (Mtd). This name is derived from the Latin term mactator which means butcher or killer. Additionally, homologous proteins were found in "Drosophila melanogaster" (fruit fly) and "Gallus gallus" (chicken). The human BOK promoter is activated by the overexpression of members of the E2F hand transcription factor family. Typically, these transcription factors are involved in the promotion of S-phase, so there might be a connection between Bok expression and cell cycle progression. Due to this regulation of Bok expression by the cell cycle, it was proposed that Bok sensitizes growing
