Abstract

Because of its poor prognosis, new modalities to treat pancreatic cancer are highly welcome. Gammalinolenate (GLA) has been shown to possess antitumor activity on various human cancer cell lines in vitro and some evidence has been found of its modulative activity on tubulin active agents, such as vinca alkaloids. GLA treatment is thought to change the penetration and distribution of chemotherapeutic agents in pancreatic tumor tissue. The in vivo effects of GLA are widely unknown. This is the first study on the modulation effects of both oral or intravenous GLA on blood perfusion in vivo. We analysed tissue perfusion prior to treatment and on the 10th day of GLA treatment in patients with pancreatic cancer. Dynamic gamma imaging was performed for 20 minutes after Tc-99m-MIBI injection, and the whole body was scanned after the dynamic study and at 4 hours. Half-lives in liver, left kidney, spleen, pancreas and tumor were recorded using a developed macro program for background corrected geometric mean data from irregular region of interests. Half-lives in the liver did not change due to oral GLA treatment, but they decreased dramatically in two of three patients after i.v. GLA treatment. Additionally, individual changes were obser...Continue Reading

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.
