Overview

Itzhak Ofek is affiliated with Tel Aviv University in Israel and has contributed to the fields of Biochemistry, Genetics and Molecular Biology, as well as Agricultural and Biological Sciences. Their work spans multiple subfields including Genetics, Animal Science and Zoology, Nutrition and Dietetics, and Physiology.

The main topics addressed by their research include:

  • Genetic Mapping and Diversity in Plants and Animals
  • Biochemical Analysis and Sensing Techniques
  • Adipose Tissue and Metabolism
  • Pharmacological Effects and Assays
  • Meat and Animal Product Quality

Ofek's recent publications reflect an interest in the pharmacogenomic effects of natural extracts on physiological traits. Their papers include:

  • Lowering fasting blood glucose with non-dialyzable material of cranberry extract is dependent on host genetic background, sex and diet (2022), published in Animal Models and Experimental Medicine
  • Studying the pharmacogenomic effect of cranberry extract on reducing body weight using collaborative cross mice (2021), published in Food & Function

Frequently collaborating with other researchers, Ofek has coauthored papers with:

  • Fatima Amer-Sarsour
  • Fuad A. Iraqi
  • Rana Tarabeih
  • Rawan Abu Saleh

Their work has appeared in journals such as Animal Models and Experimental Medicine and Food & Function, each venue hosting at least one of their studies. The research mainly explores genetic diversity, metabolic processes, and the biochemical mechanisms underlying dietary interventions in animal models. This combination of genetics and animal nutrition situates their contributions at the intersection of molecular biology and applied agricultural sciences.
