Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
Hedgehog Signaling Pathway02:33

Hedgehog 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...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

The tumor suppressor Patched1 (Ptch1) regulates skin cancer. A specific Ptch1 allele in FVB mice promotes squamous cell carcinoma (SCC) growth independently of sonic hedgehog (SHH) signaling, revealing new roles in skin tumor development.

Area of Science:

  • Oncology
  • Dermatology
  • Molecular Biology

Background:

  • Patched1 (Ptch1) is a tumor suppressor crucial for regulating sonic hedgehog (SHH) signaling.
  • Ptch1 dysfunction is linked to basal cell carcinoma (BCC) development.
  • Previous research established Ptch1's role in preventing BCCs.

Purpose of the Study:

  • To investigate the function of a naturally occurring Ptch1 allele in FVB mice.
  • To determine the role of Ptch1 in squamous cell carcinoma (SCC) formation.
  • To explore Ptch1's involvement in skin tumorigenesis beyond SHH pathway regulation.

Main Methods:

  • Utilized FVB mouse models with a specific Ptch1 allele.
  • Analyzed tumor growth and progression in skin.
  • Assessed SHH pathway activation in relation to Ptch1 function.

Main Results:

  • A naturally occurring Ptch1 allele in FVB mice promotes early SCC growth.
  • This promotion of SCC growth occurs independently of aberrant SHH pathway activation.
  • Ptch1 exhibits functions at the intersection of BCC and SCC development.

Conclusions:

  • Ptch1 has novel roles in promoting SCC growth.
  • Ptch1's function in skin cancer is not solely dependent on SHH signaling.
  • The study uncovers new insights into the complex roles of Ptch1 in skin tumor suppression and promotion.
