Securinine and ajmaline may effectively treat liver cancer, with securinine being less toxic to normal cells.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Matriptase is crucial for keeping epithelial tissues healthy and functioning properly.

Blocking a specific protein signal can make hair grow on mouse nipples.

LGR5 helps maintain corneal cell characteristics and prevents unwanted changes by controlling specific cell signaling pathways.

Quiescent cells have increased mitochondrial activity and ECM gene expression, but reduced glycolysis.

Exosomes from stem cells help repair irradiated salivary glands by boosting cell growth.

Cepharanthine may help treat gastric cancer by causing cancer cell death and affecting energy use.

EMT and metabolic pathways help cancer cells resist treatment and spread.

ROR2 is essential for hair follicle stem cell renewal and maintenance.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

Skin tumor regression is helped by retinoic acid signaling blocking Wnt signaling.

Dihydrotestosterone (DHT) doesn't affect rat skin cell growth, but it does change cell cycle, protein levels, and other cell functions, potentially shortening hair growth cycle.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

Skin cells produce and activate vitamin D, which regulates skin functions and supports hair growth.

Vitamin D and its receptor regulate skin functions like cell growth, immunity, hair cycle, and tumor prevention.

Key genes and pathways crucial for hair follicle development in cashmere goats were identified, aiding fleece production improvement.

Birds can regenerate inner ear cells using specific gene pathways, unlike mammals.

Disrupting Smad4 in mouse skin causes early hair follicle stem cell activity that leads to their eventual depletion.

Endoglin is crucial for proper hair growth cycles and stem cell activation in mice.

Special immune cells called Treg cells are important for maintaining and regenerating hair by activating a specific growth signal in hair stem cells.

Scientists made stem cells that can grow hair by adding three specific factors to them.

Mice with more Flightless I protein grew back their claws better after amputation.

Two microRNAs affect hair follicle development in sheep by targeting specific genes.

Genes related to keratin, skin cell differentiation, and immune functions are key in hedgehog skin and spine development.

The study found that certain genes are important for hedgehog skin appendage development and immunity, with spines possibly evolving for protection and infection resistance.

Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.

New treatments targeting T-cell pathways are needed for better alopecia areata management.

Early development of hair, teeth, and glands involves specific signaling pathways and cellular interactions.

Exosomes from dermal papilla cells can help grow hair and might treat hair loss.
