Summary
The Hedgehog (HH) signaling pathway is crucial for embryonic development and tissue organization. Mutations in its receptor, the patched gene (PTCH), are linked to basal cell carcinoma, suggesting PTCH inactivation is key to skin cancer development.
Area of Science:
- Developmental Biology
- Oncology
- Molecular Biology
Background:
- The Hedgehog (HH) protein family is vital for embryonic patterning in invertebrates and vertebrates.
- HH signaling regulates segment polarity and tissue organization, with roles in human development and skin cancer.
- The Sonic Hedgehog (SHH) pathway is implicated in basal cell carcinoma (BCC), the most common human cancer.
Purpose of the Study:
- To investigate the role of the patched gene (PTCH) in the etiology of basal cell carcinoma.
- To understand the significance of PTCH mutations in both sporadic and hereditary BCCs.
- To explore the potential of delineating the PTCH biochemical pathway for developing targeted cancer therapies.
Main Methods:
- Characterization of mutations in the patched gene (PTCH) in basal cell carcinoma samples.
- Analysis of sporadic and hereditary basal cell carcinoma cases for PTCH alterations.
- Biochemical pathway analysis involving PTCH function.
Main Results:
- Mutations in the patched gene (PTCH) were identified in sporadic BCCs and nevoid basal cell carcinoma syndrome.
- PTCH inactivation appears to be a critical step in the tumorigenesis of basal cell carcinoma.
- The study provides a foundation for understanding the biochemical pathway of PTCH.
Conclusions:
- The patched gene (PTCH) is frequently mutated in basal cell carcinoma, indicating its role as a tumor suppressor.
- Understanding the SHH pathway and PTCH function is essential for developing effective treatments for skin cancer.
- Targeting the PTCH pathway may offer therapeutic strategies for basal cell carcinoma and potentially other cancers.

02:33Hedgehog Signaling Pathway
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

03:14Notch Signaling Pathway
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
