Do RET and APC Crosstalk in Hirschsprungs Disease Pathogenesis?

Hirschsprungs disease with congenital hypothyroidism.

We report a female newborn baby who presented with vomiting and abdominal distension on day 21 of life. Examination revealed facial puffiness, open posterior fontanelles, dry skin, cold peripheries and prominent abdominal veins with visible peristalsis. Barium enema revealed dilated proximal colon, empty rectum, funnel like transition zone between proximal dilated and distal constricted bowel. ...

Antagonistic crosstalk between APC and HIF-1α.

Most colorectal cancers have mutations in the tumor suppressor APC. The best-understood function of APC is its participation in a protein complex that regulates the availability of β-catenin. Solid tumors are characterized by the presence of hypoxia as well as inflammation, which leads to the upregulation of Hypoxia Inducible Factors like HIF-1α. We recently demonstrated a novel antagonistic li...

Crosstalk of parkin and Ret in dopaminergic neurons

Recent genetic and functional studies have revealed striking similarities in the protein networks and molecular mechanisms altered in cancer and Parkinson's disease, as illustrated here for the converging signaling pathways of parkin and Ret [1]. These similarities may guide our thinking about potential therapies for both diseases. The proto-oncogene RET encodes a receptor tyrosine kinase that ...

Intestinal Microbiota and the Innate Immune System – A Crosstalk in Crohn’s Disease Pathogenesis

Crohn's disease (CD) is a chronic, relapsing inflammatory disorder that can occur anywhere along the gastrointestinal tract. The precise etiology of CD is still unclear but it is widely accepted that a complex series of interactions between susceptibility genes, the immune system and environmental factors are implicated in the onset and perpetuation of the disease. Increasing evidence from expe...
