Background

Pro-Gastrin-Releasing-Peptide, also known as Pro-GRP, is a Gastrin-Releasing-Peptide (GRP) precursor, a neurotransmitter that belongs to the bombesine/neuromedin B family. GRP stimulates the secretion of gastrin in order to increase the acidity of the gastric acid. Pro-GRP is a peptide composed of 125 amino acids, expressed in the nervous system and digestive tract. In pathological situations, GRP has mitogenic activity in vitro in many tumors such as pancreatic, small cell lung (SCLC), prostate, kidney, breast and colorectal cancers. GRP could operate as an autocrine growth factor. In cancers, GRP induces cell growth and inhibits apoptosis by shutting down the endoplasmic reticulum stress pathway. As early as 1994, research on Pro-GRP as a biomarker for small cell lung cancer began. Because of the very short half-life of GRP (2 minutes), the Pro-GRP is used for measurements and analysis. Since then, Pro-GRP has been used as a tumor marker for patients with small cell lung cancer (SCLC) in limited and extended stages.

Just okay
Color: Grey Striped, Size: 72"W x 84"L (Pack of 1)
Okay curtain, not great, but not bad. Looks like it has kind of a faint background design. Has a plastic type feel. Looks okay.

Pleasantly Surprised!
Color: Grey Striped, Size: 72"W x 72"L (Pack of 1)
I was looking for this exact product but didn’t know it! We recently moved into a new home and had zero window treatments so needless to say I wanted something quick, affordable and not vinyl WalMart blinds. We are happy with our purchase and would highly recommend to others. Some complain of the adhesive not sticking- make sure to clean the window wells/walls etc prior to installing these. If the surface is free of dirt/grease there will be no issues with them staying put.
