Significance of Cortactin Expression in Colorectal Adenocarcinomas

Status Completed

Clinical Trial Summary

Colorectal carcinoma is one of the most aggressive malignant epithelial neoplasms affecting the gastrointestinal tract. The incidence of colorectal carcinoma is obviously increasing in developing countries, where the physical inactivity and the consumption of animal fat-rich food became more evident. Colorectal tumorigenesis is a multistep process which is initiated by adenoma and is terminated by carcinoma, the latter shows variable degrees of tumor differentiation and invasiveness. During the adenoma-carcinoma process; a series of genetic mutations occur. Detection of these genetic mutations will help in the development of novel therapeutic agents, which in turn will improve patients' outcomes. Cortactin (CTTN) is a Src kinase substrate, encoded by a gene located on chromosome 11. CTTN binds to and activates Arp 2/3 and stabilizes the dynamic actin assembly after its formation. So, it become clear that CTTN is involved in the formation of the leading-edges cellular protrusions.

Clinical Trial Description

Colorectal carcinoma is a highly lethal malignant epithelial tumor involving humans. The incidence of colorectal carcinoma is steadily increasing in developing countries, this could be assigned to low physical activity together with high consumption of animal fat-rich food. malignancy of the colon is a multistep process which is initiated by adenoma that proceeds to carcinoma, the latter includes a wide variety of tumor phenotypes. During the adenoma-carcinoma process; a series of genetic and epigenetic alterations occur. Detection of these genetic alterations is of great benefit in the future management of colorectal carcinomas. Cortactin (CTTN) is a Src kinase substrate, encoded by a gene located on chromosome 11. CTTN anchors the dynamic actin assembly . CTTN is implicated in the formation of the leading-edges cellular protrusions.the aim of this study is to evaluate expression of CTTN in 50 cases of colorectal adenocarcinomas and their adjacent normal colonic mucosae. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
