The FDA approved a new breast cancer treatment, found flu shots may reduce heart risks, questioned the safety of fast-tracked drug approvals, showed statins don't help with certain pneumonia, and approved a new dementia imaging agent.

New skin treatments in 1987-1988 showed effectiveness for various conditions, but some had side effects or risks.

β-catenin is essential for stem cell activation and proliferation in hair follicles.

β-catenin in the dermal papilla is crucial for normal hair growth and repair.

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

Skin needs dermal β-catenin activity for hair growth and skin cell multiplication.

Stem cell niches are crucial for regulating stem cell renewal and differentiation, and understanding them can help in developing regenerative therapies.

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

Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.

Activating a protein called β-catenin in adult skin can make it behave like young skin, potentially helping with skin aging and hair loss.

Laminin-511 is crucial for early hair growth and maintaining important hair development signals.

The study found that the protein Dkk4 helps regulate hair growth by controlling Wnt signaling in mice.

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

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

Natural 5AR inhibitors effectively improve mild to moderate hair loss in men.

Dermal exosomes with miR-218-5p boost hair growth by controlling β-catenin signaling.

Activating β-catenin in different skin stem cells causes various types of hair growth and skin tumors.

Some medications can cause hair loss, but stopping the drug usually leads to recovery within 3 months.

Wnt10b makes hair follicles bigger, but DKK1 can reverse this effect.

Permanent waving weakens hair by altering its protein structure.

Using β-cyclodextrin derivatives improves the solubility and bioavailability of steroidal drugs.

Reconstructed skin models are useful for studying how skin processes certain chemicals.

Scientists created a long-lasting stem cell line from human hair that can turn into different skin and hair cell types.

Prominin-1 expressing cells in the dermal papilla help regulate hair follicle size and communication but don't aid in skin repair.

Flutamide combined with an LHRH agonist effectively inhibits prostate growth, suggesting it could treat prostate cancer.

cDermo-1 causes dense skin, feathers, and scales in chickens.

CXXC5 is a protein that controls cell growth and healing processes, and changes in its activity can lead to diseases like cancer and hair loss.

Removing vitamin D and calcium receptors in mice skin cells slows down skin wound healing.

Adenosine helps hair grow longer and stronger by boosting certain growth factors and signaling pathways.

PBX1 helps hair stem cells grow and change by turning on certain cell signals and preventing cell death, which may be useful for hair regrowth treatments.
