    Thanks jwkrahn for the reply. However, it is not producing the desired output. The output I am getting is:

    A and B %regulate% each other in cells

      By using "x", he changed the meaning of the spaces in your pattern. Fixed: 
      $sentence =~ s{($phrases)}{
    ( my $string = $1 ) =~ tr/ /_/;
    "%$string%"
}ieg;
