background: prostate cancer after lung cancer is the second cause of cancer-associated death in men. in recent years, targeted therapy of cancer has attracted researchers attention. the targeted therapy lead to decrease in side effects of drugs. studies have indicated that targeting peptides for cancer cells represent valuable tools for diagnostic and therapeutic. recently, phage display peptid...

Systemic 1,25(OH)2D3 treatment ameliorating murine inflammatory bowel diseases (IBD) could not be applied to patients because of hypercalcemia. We tested the hypothesis that increasing 1,25(OH)2D3 synthesis locally by targeting delivery of the 1α-hydroxylase gene (CYP27B1) to the inflamed bowel would ameliorate IBD without causing hypercalcemia. Our targeting strategy is the use of CD11b(+)/Gr1...

In addition to their role in absorption and secretion, epithelial cells play an important role in the protection of the colon mucosa from the resident microbiota and are important for the maintenance of homeostasis. Microarray analysis of intact colon samples is widely used to gain an overview of the cellular pathways and processes that are active in the colon during inflammation. Laser microdi...

Although there is evidence that galectin-9 is a critical factor in health and disease, the upstream regulatory microRNA (miRNA or miR) of the protein remains poorly defined. miR-455-5p is characterized as a tumor-associated miRNA in cancer research. However, the actual role of miR-455-5p with respect to inhibiting or promoting tumorigenesis in colon cancer is unclear. The present study aimed to...

A cancer phenotype is driven by several proteins and targeting a cluster of functionally interdependent molecules should be more effective for therapeutic intervention. This is specifically important for Ras-dependent cancer, as mutated (MT) Ras is non-druggable and targeting its interaction with effectors may be essential for therapeutic intervention. Here, we report that a protein-complex act...

Background: Colon cancer begins in the large intestine (colon) and is aggressive due to late diagnosis, so there a poor prognosis higher mortality rates, as reported. has become vital research area requiring more investigation of cellular signaling its initiation development. Aim: The study aimed investigate biological effects Glycerol cell proliferation possible regulation by exogenous treatme...

objective: recently, phage display libraries have received enormous attention for identification and isolation of pharmaceutical molecules with diagnostic and therapeutic properties. peptide libraries are known as one of the most important and widely used types of phage display libraries. in the current study, we aimed to screen the ph.d.tm-7 phage display peptide library through biopanning for...

conclusions it was shown that combination of pectin and eudragits can relatively control drug release in the upper gi. on the other hand, pectin degraded in the presence of pectinase and formulations were susceptible to the colonic media. results it was shown that in the presence of pectin, formulations without erl had a relative resistance to drug release in sgf. pellets containing pectin and ...

Colon cancer is still a burden mainly due to metastasis formation. The latter is often associated with a constitutive activation of the Wnt/beta-catenin signaling pathway and high expression of the metastasis-inducing gene S100A4. We previously identified S100A4 as a transcriptional target of beta-catenin. Intervention strategies targeting Wnt/beta-catenin signaling might therefore represent pr...

Members of the Ras protooncogene family are mutated in approximately 75% of colon cancers. The Raf kinases (Raf-1, b-Raf and a-Raf) directly interact with Ras and serve as mediators of mitogenic signals. Expression of the constitutively active alleles of Raf or Ras gene families results in oncogenesis in a number of model systems. Previous studies...
