multifunctional nanomaterials showed graet advantages in drug delivery. folic acid (fa) binding protein, a glycosyl phosphatidyl inositol anchored cell surface receptor for folate, is overexpressed in several human tumors, whereas it is highly restricted in normal tissues. therefore, in this study, fa, polyethylene glycol (peg), and fe3o4 nanoparticles multifunctionalized short multiwall carbon...
Efflux transporters such as P-glycoprotein and multidrug resistance-associated proteins (MRPs) in the intestinal wall restrict intestinal drug transport. To overcome this limitation for enteral drug absorption, galenical targeting approaches have been proposed for site-specific luminal drug release in segments of the gut, where expression of the respective absorption-limiting transporter is min...
Several studies have reported that activated receptor tyrosine kinases (RTKs) are highly expressed in colon cancer and may promote tumor growth and survival. However, there is little information available as to the function and signaling of RTKs in colon cancers. In the present study, we performed protein array technology to determine the expression status of various RTKs that are activated in ...
The aim of the present study was to identify the differentially expressed microRNAs (miRNAs or miRs) in patients with colon cancer and examine their roles in the pathogenesis of the disease. The expression profiles of miRNAs were examined in tumor tissue samples collected from 20 patients with histologically confirmed colon cancer and in the adjacent non-cancerous control tissues using microarr...
