Angiotensin II (Ang II) Description



Angiotensin II (Ang II) is an octapeptide hormone that plays a axial role in cardiovascular homeostasis. Typical of abounding proteins, Ang II was called on the base of its first-demonstrated biological function—the adeptness to act as a vasoactive agonist and abet abbreviating of claret vessels. Over the years, Ang II has been apparent to play important roles in mediating hypertension, affection failure, cardiac remodeling, diabetes, and the proliferative and anarchic responses to arterial abrasion (see review1). These allegation accept spawned the development of several classes of pharmacological agents advised at inhibiting the amalgam of Ang II (eg, angiotensin II-converting agitator inhibitors) or blocking its activity (eg, angiotensin II receptor antagonists). These agents are now broadly acclimated in the analysis of hypertension and congestive affection failure.

CEA Description


CEA is a actuality commonly begin in a fetus which, if begin at animated levels in the claret of adults, may announce the attendance of colorectal blight or added types of cancer. CEA is accordingly alleged a bump marker.
It has been acclimated to adviser patients for the ceremony of a amount of altered cancers, including breast, thyroid, lung, ovarian, pancreatic, stomach, and colon/rectal. It is aswell referred to as an "oncofetal antigen" because of its affinity to fetal tissue.

CEA levels can aswell be an adumbration of the capability of treatment.

IGFBP-3 Clinical significance


IGFBP-3 protein levels abatement during the progression of prostate blight from amiable to metastatic disease. Although, assembly of the protein does not cease completely. IGFBP3 is still fabricated (at a lower level) by prostate blight beef and buried into the surrounding environment. However, instead of the abounding length, anatomic protein, IGFBP3 is begin to be cleaved. This prevents IGFBP3 from bounden and sequestering IGFs and the advance factors are chargeless to bind the IGF-1R and advance corpuscle survival.
