RESEARCH: CANCER
FOLDING PROJECT #15207 PROFILE

The project relates to how PTCH1 moves cholesterol around in cells. This protein is important for stopping cancer growth, but when it doesn't work right, cancers like medulloblastoma and basal cell carcinoma can develop. By understanding how PTCH1 moves cholesterol, scientists hope to find 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.

PTCH1

Patched homolog 1 protein

PTCH1 is a gene that codes for a protein involved in the Hedgehog signaling pathway. This pathway plays a crucial role in embryonic development and tissue homeostasis. Mutations in PTCH1 can lead to developmental abnormalities and cancer.

---

SMO

Smoothened

SMO is a transmembrane protein that acts as a key component in the Hedgehog signaling pathway. Activation of SMO triggers downstream signaling events that regulate cell growth and differentiation.

---

SHH

Sonic hedgehog

SHH is a signaling protein belonging to the Hedgehog family. It plays a vital role in embryonic development, tissue regeneration, and cancer progression.

---

cholesterol

A waxy, fat-like substance found in all cells of the body.

Cholesterol is an essential component of cell membranes and plays a crucial role in various biological processes. It is also a precursor to hormones and bile acids.

---

transmembrane protein

A protein that spans the cell membrane.

Transmembrane proteins are essential for various cellular processes, including transport of molecules across the cell membrane, signal transduction, and cell adhesion.

---

cancer

A group of diseases characterized by abnormal cell growth and spread.

Cancer is a complex disease caused by mutations in genes that control cell growth and division. These mutations can lead to uncontrolled cell proliferation and the formation of tumors.

---

medulloblastoma

A type of brain tumor that arises in the cerebellum.

Medulloblastoma is a highly aggressive childhood brain tumor. It typically affects the cerebellum, which controls balance and coordination.

---

basal cell carcinoma

A type of skin cancer that originates in the basal cells.

Basal cell carcinoma is the most common type of skin cancer. It typically appears as a pearly or waxy bump and can grow slowly.
