Understanding GH and JAK-STAT Pathway

What is the primary function of the JAK enzyme in the JAK-STAT pathway?

• It acts as a hormone receptor.

• It phosphorylates the receptor and STAT.

• It translocates to the nucleus.

• It regulates gene expression.

Which hormone, besides growth hormone (GH), utilizes the JAK-STAT pathway?

• Insulin

• Cortisol

• Prolactin

• Thyroxine

What structural resemblance does growth hormone (GH) have with another hormone?

• Insulin

• Prolactin

• Cortisol

• Estrogen

What is the role of STAT in the JAK-STAT pathway?

• It binds to the hormone receptor.

• It phosphorylates JAK.

• It dimerizes and regulates gene expression.

• It increases blood glucose levels.

What is the full form of JAK in the JAK-STAT pathway?

• Janus kinase

• Joint kinase

• Junction kinase

• Juvenile kinase

What is the full form of STAT in the JAK-STAT pathway?

• Signal transducer and activator of transcription

• Signal transmitter and activator of transcription

• Signal transducer and activator of translation

• Signal transmitter and activator of translation

What is the primary role of IGF-1 in the body?

• Decreasing bone mineral density

• Enhancing muscle mass

• Reducing blood glucose levels

• Inhibiting bone growth

How does growth hormone (GH) affect insulin sensitivity?

• It increases insulin sensitivity.

• It decreases insulin sensitivity by lowering blood glucose levels.

• It decreases insulin sensitivity by raising blood glucose levels.

• It has no effect on insulin sensitivity.

Which of the following is an adverse effect of recombinant growth hormone?

• Hyperglycemia

• Peripheral edema

• Hypotension

• Bradycardia

What is myalgia, an adverse effect of recombinant growth hormone?

• Joint pain

• Muscle pain

• Bone pain

• Nerve pain
