Deleting the PTEN gene in mice causes nerve cells to grow larger and heal better after injury, but may cause overgrowth and hair loss in older mice.

Deleting the MAD2L1 gene in mice led to rapid tumor growth despite chromosomal instability.

Inactive hair follicle stem cells help prevent skin cancer.

Exosomes help nerve fibers grow by affecting specific cell signaling pathways.

Melanoma development can be linked to the breakdown of skin's melanin-producing units.

Breast cancer treatments work better with AR activation, improving results and reducing side effects.

PTEN helps control the number and health of skin stem cells by working with the protein BMAL1.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

The conclusion is that understanding how hair follicle stem cells live or die is important for maintaining healthy tissue and repairing injuries, and could help treat hair loss, but there are still challenges to overcome.

Not having enough or having too much of the protein Grainyhead-like 3 leads to various developmental problems.

Tumor suppressors help control inflammation in cancer and restoring their function could lead to new treatments.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Deleting the MAD2L1 gene is tolerated in certain mouse cancer models.
