New CRISPR/Cas9 variants and nanotechnology-based delivery methods are improving cancer treatment, but choosing the best variant and overcoming certain limitations remain challenges.

Enzymes are classified into six types and are essential for many biological processes, with only a few targeted by drugs.

Key genes and RNAs related to hair growth in sheep were identified, aiding future breeding improvements.

Multi-omics techniques help understand the molecular causes of androgenetic alopecia.

Ephrins slow down skin and hair follicle cell growth.

Stem cells control their future role by changing ERK signal timing, affecting tissue regeneration and cancer.

Cyclooxygenase-2 overexpression in mice skin causes hair loss like human androgenetic alopecia.

Human hair follicle cells can be successfully transformed into different types of cells, but not more efficiently than other adult cells.

Calcium is important for stem cell function and maintenance, especially in blood and skin cells.

Mouse skin glands need healthy nerves to grow properly during hair growth phases.

Hair follicles repair 3D injuries using a 2D healing process.

Stem cell niches are adaptable and key for tissue maintenance and repair.

The research suggests that Tourette syndrome is linked to both brain signaling and immune system pathways.

The document concludes that understanding dermal papilla cells is key to improving hair regeneration treatments.

Hair and skin can regenerate without bulge stem cells due to other compensating cells.

Progranulin overexpression leads to shorter, thinner hair and increased cell death in mouse hair follicles.

Warts in HIV-positive men can have serious abnormal cell growth, needing careful analysis and treatment to prevent cancer.

Drug metabolism affects how long a drug works, its interactions, activation, and toxicity, and is influenced by genetics, diet, illness, and other drugs.

MOF controls key genes for skin development by regulating mitochondrial and ciliary functions.

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.

Activating Wnt in skin cells controls the number of hair follicles by directing cell movement and fate.

Obesity can weaken the skin's ability to fight infections because fat cells stop and reduce the infection-fighting properties of nearby stem cells.

New drugs targeting the JAK-STAT pathway show promise for treating inflammatory skin diseases.

Some nutrients and antioxidants may improve skin and hair health, but more research is needed to confirm these benefits.

Maintaining DNA integrity in stem cells is crucial to prevent aging and cancer.

Lower adrenal hormone levels may cause hair loss in postmenopausal women, certain patterns help diagnose nail cancer, and a gene variant linked to higher skin cancer risk in kidney transplant patients suggests monitoring folate levels.

Targeting colon cancer stem cells might lead to better treatment results.

Melatonin in the skin helps protect against damage from stress and UV rays, and could be used to treat certain skin conditions.

Human skin can make serotonin and melatonin.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.
