Interspecies signaling between Veillonella atypica and Streptococcus gordonii requires the transcription factor CcpA.

Streptococcus gordonii and Veillonella atypica, two early-colonizing members of the dental plaque biofilm, participate in a relationship that results in increased transcription of the S. gordonii gene amyB, encoding an alpha-amylase. We show that the transcription factor CcpA is required for this interspecies interaction.

Expression and functions of transmembrane mucin MUC13 in ovarian cancer.

MUC13, a transmembrane mucin, is normally expressed in gastrointestinal and airway epithelium. Its aberrant expression has been correlated with gastric colon and cancer. However, the expression and functions of MUC13 in ovarian cancer are unknown.
