Let-7 and miR-143 miRNA? - (Oct/01/2011 )

Dear All
Since I am new to miRNA research area, I have been searching the Pubmed to know whether Let-7 and miR-143 miRNA are physiologically related, but could not find an answer. Is there a database that can illucidate whether miR-143 belongs to Let-7 family?
thanks
