FOLDING PROJECT #15212 PROFILE

This project looks at how PTCH1 moves cholesterol around in our cells. PTCH1 helps control the hedgehog pathway, which is important for growth. Problems with this pathway can lead to cancers like medulloblastoma and basal cell carcinoma. Understanding how PTCH1 works could lead to new cancer treatments.

Note: This TLDR is a simplication and may not be 100% accurate.

This project aims to elucidate the cholesterol transport mechanism in PTCH1, a transmembrane protein responsible for inhibiting SMO in the absence of SHH in the hedgehog signaling pathway by reducing access to ciliary membrane cholesterol.

Dysregulation of this pathway (such as the inability of PTCH1 to transport cholesterol and thereby inhibit SMO) has been linked to various cancers, including medulloblastoma and basal cell carcinoma.

Thus, understanding the mechanisms behind PTCH1 cholesterol transport will allow for therapeutic treatments to target these cancers.

cholesterol

A waxy, fat-like substance essential for cell function.

Cholesterol is a vital component of cell membranes and is necessary for various bodily processes. However, high levels can contribute to heart disease.

PTCH1

Patched 1

PTCH1 is a gene that encodes a protein involved in the Hedgehog signaling pathway. It regulates cell growth and differentiation.

---

SMO

Smoothened

SMO is a protein that plays a crucial role in the Hedgehog signaling pathway. Its activation promotes cell proliferation and survival.

---

SHH

Sonic Hedgehog

SHH is a signaling protein involved in embryonic development and tissue regeneration. It plays a role in cell growth and differentiation.

---

hedgehog signaling pathway

A cellular signaling pathway that regulates cell growth and differentiation.

The Hedgehog signaling pathway is crucial for embryonic development and tissue maintenance. It controls cell fate decisions and influences processes like bone growth and cancer.

---

medulloblastoma

A type of brain tumor that arises from the cerebellum.

Medulloblastoma is a malignant brain tumor primarily affecting children. It grows rapidly and can spread to other parts of the body.

---

basal cell carcinoma

The most common type of skin cancer.

Basal cell carcinoma is a slow-growing skin cancer that arises from the basal cells in the epidermis. It is often caused by excessive sun exposure.
