The spelling of the word "TGFRI" can be a bit confusing at first glance. However, if we break it down using IPA phonetic transcription, we can see that it represents the initials of a gene, rather than a word. "TGFRI" is pronounced as "ti-dʒi-ɛf-ɑr-ai" and stands for the Transforming Growth Factor Beta Receptor I gene. This gene plays a crucial role in regulating cellular growth and differentiation, making it an important target for cancer research and drug development.
