Thermoregulation via sweating

Childbirth contractions via oxytocin release

Blood clotting via fibrin action

Ovulation via the luteinizing hormone (LH) surge

Lactation via prolactin production

A cell senses that the concentration of a protein is too high and represses transcription of the gene encoding the protein

A cell senses too much sugar in the blood and turns on transcription of the insulin gene

A cells senses too little sugar in the blood and turns on transcription of the glucagon gene

A cell senses that there is too little of a protein within a cell and activates transcription of the gene encoding the protein
