What is the machaism of steroid hormone cascade pathway?

Answer 1

The steroid hormone cascade pathway begins when a steroid hormone, such as cortisol or estrogen, diffuses through the cell membrane and binds to its specific intracellular receptor. This hormone-receptor complex then translocates to the nucleus, where it binds to specific DNA sequences, regulating the transcription of target genes. This process ultimately leads to the synthesis of proteins that mediate various physiological responses. The pathway is characterized by its relatively slow onset of action, as it involves changes in gene expression and protein synthesis.
