In his most recent research, the most cited papers focused on:

  • Gene
  • Enzyme
  • Internal medicine

Hamid M. Said focuses on Biochemistry, Molecular biology, Intestinal absorption, Transporter and Cell biology. The various areas that Hamid M. Said examines in his Molecular biology study include Intestinal mucosa, Downregulation and upregulation, Promoter, Messenger RNA and Regulation of gene expression. His work carried out in the field of Intestinal absorption brings together such families of science as Endogeny, Homeostasis, In vivo and Large intestine.

The concepts of his Transporter study are interwoven with issues in Apical membrane and Brown–Vialetto–Van Laere syndrome. His research integrates issues of Chromatin immunoprecipitation, Caco-2 and Intestinal permeability in his study of Cell biology. His Biotin study integrates concerns from other disciplines, such as Proinflammatory cytokine, Internal medicine, Pantothenic acid and Endocrinology.
