Understanding factors influencing cancer development is crucial. Modern molecular approaches and transgenic animals improve the accuracy and reliability of carcinogenicity bioassays for identifying carcinogens.

Area of Science:

  • Oncology
  • Molecular Biology
  • Toxicology

Background:

  • Carcinogenesis is influenced by various factors like species, metabolism, age, and diet.
  • Uncontrolled modulators have historically introduced uncertainty into carcinogenicity bioassays.
  • Molecular carcinogenesis research aims to elucidate these modulatory effects.

Purpose of the Study:

  • To understand the molecular basis of known carcinogenesis modulators.
  • To enable genetic modulation of carcinogenesis in experimental models.
  • To improve the sensitivity and specificity of carcinogenicity bioassays.

Main Methods:

  • Investigating the role of oncogenes and tumor suppressor genes.
  • Utilizing transgenic animal models in carcinogenicity bioassays.
