title: Amino acid requirements for the growth of Aedes albopictus clone C6/36 cells and for the production of dengue and Chikungunya viruses in the infected cells.
abstract: Amino acid requirements for the growth of Aedes albopictus, clone C6/36, cells and for the production of dengue (DEN) and Chikungunya (CHIK) viruses were examined by growing the cells or the viruses in media which were deprived of one of the 20 amino acids. Cell growth was markedly inhibited when cystine was omitted from the medium, and to a lesser extent by arginine deprivation. On the other hand, omission of alanine, asparagine, aspartic acid, and glutamic acid at the same time did not affect cell growth. Marked accumulation of alanine was observed in the medium when the cells were grown for 8 days in complete medium, with concomitant depletion of aspartic acid and glutamic acid. The production of CHIK virus was inhibited markedly by omission of cystine from the medium after virus infection, while the production of DEN viruses was more affected by glycine deprivation, although cystine deprivation also inhibited virus production to a lesser extent. On the other hand, production of CHIK and DEN viruses was not affected when alanine, asparagine, aspartic acid, and glutamic acid were omitted from the medium at the same time.
