Answer:
During exercise, your heart typically beats faster so that more blood gets out to your body. Your heart can also increase its stroke volume by pumping more forcefully or increasing the amount of blood that fills the left ventricle before it pumps.
Explanation:
An adrenal gland can develop an uncommon, often benign (noncancerous) tumor called a pheochromocytoma.
- A (pseudo)hypoxic signature is seen in many solid tumors, such as paraganglioma (PGL) and pheochromocytoma (PHEO). It has been demonstrated that (pseudo)hypoxia encourages the development of tumors and therapeutic resistance.
- Hypoxia-inducible factors (HIFs) are the main mediators of the transcriptional hypoxic response.
- The transcription of hypoxia-responsive genes, which are involved in cancer, is induced by high levels of HIFs. Catecholamine-producing tumors called PHEOs and PGLs develop from sympathetically or parasympathetically generated chromaffin tissue.
- HIF signaling appears to be crucial for the growth and development of PHEOs and PGLs, which may point to novel therapeutic strategies for the management of these malignancies.
