Napa cabbage choy (from the Cantonese name, ), and celery cabbage. In the United Kingdom this vegetable is known as Chinese leaf, in New Zealand as wong bok or won bok, and in the Philippines as wombok or pechay baguio. The name wombok is also used in Australia. Another name used in English is petsai or pe-tsai. In Russia it's called pekinskaya kapusta (), literally "Peking cabbage". The first notation of Napa cabbage cultivation date from the 15th Century in the Yangtze River region in China. Then it spread to Korea and Japan. Beginning in the 19th Century with the Chinese diaspora,
BOK (gene) of Bok to its interacting partners seems to be mediated by its BH3 domain. The splice variant Bok-S lacks this domain and is unable to form heterodimers with other proteins of the Bcl-2 family. In yeast two-hybrid experiments, Bok was found to interact with the anti-apoptotic proteins Mcl-1, BHRF-1, and Bfl-1. However, interactions with other anti-apoptotic proteins such as Bcl-2, Bcl-xL, and Bcl-w were not detectable (1). Later studies aimed at confirming an interaction between Bok and pro-apoptotic Bak or Bax but were not successful. Accordingly, coexpression of anti-apoptotic proteins such as Mcl-1 suppresses apoptosis induced by Bok overexpression. Consistent
