This invention is directed to prostaglandin E2 receptor 4 (EP4) antagonists useful in the treatment of nonalcoholic steatohepatitis (NASH)-associated liver cancer in a human or animal. The method comprises administering one or more of Compound A, Compound B or Compound C, or pharmaceutically acceptable salts thereof, as the EP4 antagonist(s). The method may include a pharmaceutical composition comprising the EP4 antagonist, and may include one or more other active agents and/or therapies.

Use of EP4 receptor antagonists for the treatment of NASH-associated liver cancer

The present invention provides a method for screening for a food ingredient or a food composition that reduces a cancer risk and inhibits cancer development. A substance that reduces a cancer risk is screened by administering a candidate substance and analyzing alteration in gut microbiota or a metabolite produced by an intestinal bacterium. Also, candidate substances are screened by adding each candidate substance to a bacterial culture system and analyzing its effect on a bacterium involved in cancer development.

Method for screening food ingredients and food compositions

The present invention provides a method capable of detecting a cancer and/or a carcinogenic risk, and a reagent for the detection thereof. The present invention also provides a method for screening for a pharmaceutical drug for reducing a carcinogenic risk and a pharmaceutical composition. Since cancer development closely correlates with alteration in gut microbiota, cancer development and/or a risk of cancer development are detected by detecting alteration in gut microbiota and a secondary bile acid produced by an intestinal bacterium. The present invention further provides a method for screening for a pharmaceutical drug with a gut microbiota as an index, and a pharmaceutical composition.
