text: Here are some GeneRIFs taken from Entrez Gene for GeneID 7157, the human gene TP53.
  The PubMed document identifiers have been omitted from the examples.  Note the wide variability with respect to the presence or absence of punctuation and of sentence-initial capital letters.
  * p53 and c-erbB-2 may have independent role in carcinogenesis of gall bladder cancer
  * Degradation of endogenous HIPK2 depends on the presence of a functional p53 protein.
  * p53 codon 72 alleles influence the response to anticancer drugs in cells from aged people by regulating the cell cycle inhibitor p21WAF1
  * Logistic regression analysis showed p53 and COX-2 as dependent predictors in pancreatic carcinogenesis, and a reciprocal relationship to neoplastic progression between p53 and COX-2.
  GeneRIFs are an unusual type of textual genre, and they have recently been the subject of a number of articles from the natural language processing community.
