Targeting nerve growth factor may cure liver cancer

September 19, 2007

Nerve growth factor (NGF), as the name says, is an essential peptide factor for the growth and differentiation of neuronal cells. Therefore we can imagine that this growth factor is important for the nervous system including brain. But a recent scientific report published in the October 7 issue of the World Journal of Gastroenterology tells us another surprising and exciting discovery about this growth factor: NGF is positively related with liver cancer, the No.2 killer among all kinds of cancers in the world.

This research was collaboration among scientists from National Research Council of Italy, Marino Hospital in Rome, Regina Elena Cancer Institute in Rome, and University of Rome. This fruitful collaboration was under the leadership of Dr Annalucia Serafino, a talented biologist who has made her well-recognized reputation in cancer research and hepatitis C virus research. She is holding a senior researcher position in the national research council in Rome, which plays a similar role as the National Institutes of Health in the United States.




With many beautiful pictures of immunohistology, these scientists showed that NGF and its receptor trkANGF were expressed in the liver of the patients troubled with liver cirrhosis and/or hepatocellular carcinoma (HCC) while these two molecules are not detected in the liver of healthy people. For a growth factor to affect a cell, there should be its specific receptor expressed on the surface of the target cell. Since both NGF and its specific receptor are abnormally expressed in the liver of patients, NGF seems to be expressed by liver cells to affect themselves (so called autocrine) or to affect adjacent cells (so called paracrine) in patients with liver cirrhosis and/or HCC.

These important discoveries indicate that NGF is playing a critical role in the development of liver cirrhosis and its progression towards HCC. Based on this discovery, targeting the NGF or its specific receptor trkANGF in diseased liver may suppress or prevent the development of liver cirrhosis and HCC. In the near future, bioengineers may be able to design a medicine directed to liver to inactivating NGF or its receptor.

The discovery reported in this article also opens up the possibility to use NGF in the early diagnosis of liver cirrhosis and HCC because of the high and specific expression of this growth factor in the liver progressing into liver cirrhosis and/or HCC.

Mayo Clinic's new imaging technology accurately identifies a broad spectrum of liver disease
A new study shows that an imaging technology developed by Mayo Clinic researchers can identify liver fibrosis with high accuracy and help eliminate the need for liver biopsies. Liver fibrosis is a common condition that can lead to incurable cirrhosis if not treated in time.

If the diabetes has a direct carcinogenetic effect?
The association of DM2 with solid tumors, and particularly with HCC, has been long suspected and several studies have reported increased mortality rates for neoplastic diseases in patients with DM2.

Toxic Bile Damages the Liver
Researchers at the Heidelberg University Hospital have discovered a new genetic disease that can lead to severe liver damage. Because a protective component of the bile is missing, the liver cells are exposed to the toxic components of the bile, resulting in cirrhosis of liver, a transformation of liver cells into connective tissue with a gradual loss of liver function.

The risk factors of idiopathic pulmonary fibrosis in HCV patients
Hepatitis C virus (HCV) is one of the more common causes of chronic liver disease in world with a variety of extrahepatic complications such as essential mixed cryoglobulinemia, membranoproliferative glomerulonep hritis, autoimmune thyroiditis, sialadenitis, and cardiomyopathy.

How to differentiate macro-regenerative nodules from hepato-carcinoma?
BA, the congenital absence or destruction of intra- or extra-hepatic biliary system, affects about 5 - 10/100 000 live births. End stage liver cirrhosis developed in some BA patients later in life.

An effective strategy for inhibition of cirrhosis
In China, the incidence of liver cirrhosis is still high, although new therapeutic approaches have recently been proposed, there is no established therapy for liver fibrosis, and Authors investigated the prevention effects of Chinese Medicine Qianggan-Rongxian Soup on liver fibrosis induced by DMN in rat.

How to select anti-hepatitis B virus agents for drug-resistance patients?
HBV infection may lead to acute liver disease, chronic active hepatitis, liver cirrhosis, and hepatocellular carcinoma. Over 350 million people worldwide are estimated to be infected chronically by HBV and are therefore at risk of liver failure, cirrhosis, or hepatocellular carcinoma.

New lights on the pathogenic mechanisms of liver cirrhosis with ascites
The pathogenic mechanisms implicated in the failure of intestinal barrier in cirrhosis have not been fully elucidated as yet and remains to be investigated.

Noninvasive test accurately identifies advanced liver disease without biopsy
Non-invasively measuring liver stiffness with transient elastography accurately diagnoses patients with late-stage liver disease, reports a new study in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association (AGA) Institute.

To protect against liver disease, body puts cells 'under arrest'
A stable form of cell-cycle arrest known to offer potent protection against cancer also limits liver fibrosis, a condition characterized by an excess of fibrous tissue, according to a new report in the August 22nd Cell, a Cell Press publication.

Liver Cirrhosis

The rise in hepatocellular carcinoma (HCC) mortality rates has caused researchers to focus increased attention on liver cirrhosis, a pathological condition known to lead to HCC. If hepatic fibrosis can be controlled, it follows that the risk of HCC among patients with chronic hepatitis can be reduced. In the quest for greater understanding of liver cirrhosis, the 1999 Yamaguchi Symposium on Liver...

Liver cirrhosis is a leading cause of morbidity and mortality worldwide. It is the fifth most common cause of death between the ages of 25 and 45. To date it is not possible to inhibit or reverse progression of cirrhosis in most patients. Accordingly, clinicians have to deal primarily with the various complications of cirrhosis, while liver transplantation is only available for selected patients....
