Biography

Dr. Dash received his Ph.D from the All India Institute of Sciences, New Delhi, India in 1991. His graduate work involved characterizing a putative receptor of Hepatitis B virus envelope protein on human liver cells. Dr. Dash moved to Tulane as a post-doctoral fellow under Professor Michael A. Gerber. There he finished six years of post-doctoral training, working on Hepatitis C in the Department of Pathology and Laboratory Medicine. In 1995 Dr. Dash was promoted to Research Assistant Professor in the Department of Pathology.

Research

The liver is the largest solid organ of the human body. It is located on the right side of the abdomen behind the ribs. The liver is responsible for protein, carbohydrate, lipid metabolism, secretes bile, detoxifies harmful substances, purifies our blood, manufactures vital nutrients, and helps with blood clotting. The liver is often affected by primary malignant tumors such as hepatocellular carcinoma (derived from hepatocytes) and cholangiocarcinoma (derived from bile ducts). According to the National Cancer Institute, hepatocellular carcinoma (HCC) is the 4th common cancer in the world. It is also called primary liver cancer because it arises from hepatocyte, which is the major cell type of the liver. The cause of hepatocellular carcinoma is unknown but contributing factors include viral hepatitis (hepatitis B and hepatitis C), cirrhosis, hemochromatosis, and toxins (especially aflatoxins) found in foods in parts of Africa and Asia. This organ is also more frequently affected by secondary malignant diseases derived from a variety of cancers such as colorectal carcinoma, carcinomas of the stomach, pancreas, lungs, breast and malignant melanomas.

Hepatitis C virus is a blood borne infectious disease that affects the liver. The majority of people infected with this virus end up with a chronic infection.  Since the infection does not have any symptoms, many individuals do not know that they carry the virus until it has already done significant liver damage 10 to 20 years later. Chronic HCV infection damages the liver and causes liver cirrhosis and cancer.  There is no treatment for liver cirrhosis and cancer. Most of these patients seek liver transplantation. There are no vaccines available currently for the prevention of HCV infection. The FDA approved treatment for chronic HCV infection is alpha interferon, ribavirin along with one of the protease inhibitors. Many patients develop resistance to this interferon -based therapy. There are approximately 170 million people infected with HCV worldwide, including 1.7 million in the United States. The social, medical and economic burden of HCV infection is enormous. The molecular details of why some patients do not respond to standard interferon therapy are currently unknown. This could be partly related either to specific hepatitis C viral strains that show persistent infection in the liver by inhibiting interferon response, or defects in the host cell response to interferon. The patients who do not respond to interferon treatment, experience long-term inflammation of liver and are at increased risk of developing liver cirrhosis and liver cancer. Pathology hepatitis research lab along with Dr. Balart and Dr. Schores investigate the cause of HCV resistance to current treatment. Research program focused on two major aspects of the disease namely: (i) To understand the mechanism of interferon resistance and virus persistence and to find out why some patients respond to treatment and why some do not. Understand how the IL-28B genotype contributes to the treatment clearance. (ii) We have developd alternative intracellular treatment approach using combinatorial siRNAs to treat chronic HCV infection that do not responds to interferon.

The mechanism(s) by which HCV cause liver cancer is complex. During the last few years our focus has been to prevent HCV-related hepatocellular carcinomas by developing an effective strategy to inhibit virus replication and production. We have been able to successfully grow hepatitis C virus outside the liver in a cell culture. We demonstrated that this culture is infectious since viral particles derived from HCV-cell culture cause persistent infection in a chimpanzee model. To visualize the replication of hepatitis C virus in living cells, scientists in our hepatitis research laboratory has fused it to green fluorescence protein in frame using one of the non-structural proteins of HCV (NS5A).   Liver cells replicating this virus emit a green fluorescent signal when exposed to a specific wavelength of light. This allows direct visualization of the tiny microscopic viral factories inside the cells (see the picture on the left). HCV-cell culture models are currently being utilized in our laboratory to understand the antiviral action of interferon alpha and mechanisms of interferon and ribavirin resistance. We have developed an intracellular treatment approach to eliminate chronic infections using genetically engineered recombinant human antibodies targeted to the viral NS3 helicase enzyme and small hairpin RNAs targeted to the highly conserved 5'UTR region. In the future, our research will lead to an effective intracellular treatment approach for chronic hepatitis C patients who are not responding to interferon therapy. This will reduce the incidence of hepatocellular carcinomas due to hepatitis C. The hepatitis research laboratory is also conduct basic research to understand the mechanism of cancer metastasis to the liver (secondary liver cancer) in order to develop effective therapeutic strategy that will prevent secondary liver cancer. The significance of these accomplishments has been recognized by my peers through the publication records and continuous support from the National Cancer Institute for the laboratory.
