Odors epigenetically effect differences in genetic predispositions

Physics

No two people smell the same Excerpt: “A difference at the smallest level of DNA—one amino acid on one gene—can determine whether you find a given smell pleasant. A different amino acid on the same gene in your friend’s body could…

Nutrient-dependent pheromone-controlled stickleback evolution

translocated chromosome

Sexual imprinting on ecologically divergent traits leads to sexual isolation in sticklebacks Excerpt: “Odour differences may be owing to pleiotropic effects of adaptive differences in diet [18], habitat [12] and major histocompatibility complex (MHC) alleles selected by parasite differences [19,20].”…

Pheromones and cancer

diseases-disorders

Transcription Factor-MicroRNA-Target Gene Networks Associated with Ovarian Cancer Survival and Recurrence Excerpt: “MicroRNAs (miRNAs) are small, non-coding RNA molecules that bind to complementary sequences on target mRNA transcripts, and thus, regulate gene expression at the post-transcription stage. Transcription factors (TFs)…
