A new mutation in the mitochondrial DNA was found in a boy with MELAS, even though his family didn't show typical signs.

Decomposed tritiated thymidine is less accurate for DNA tracing, and hair changes can indicate malnutrition.

DNMT3A is crucial for healthy skin and hair growth.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

A patient with a rare disease had a unique genetic mutation linked to their symptoms.

Researchers created a mouse with the same mutation as humans with trichothiodystrophy, showing similar symptoms and confirming the condition is due to defects in DNA repair and gene activity.

A new classification for trichothiodystrophy helps identify genetic causes and potential treatments.

Trichothiodystrophy is a rare genetic disorder causing hair issues and sometimes linked to DNA repair defects.

The study found two new mutations in a Chinese patient with severe biotinidase deficiency.

TTD patients don't have a higher skin cancer risk because their main issue is with transcription, not DNA repair.

Aging reduces stem cell activation, leading to hair loss in mice lacking a specific enzyme.

Reducing Tyrosinase prevents mature color pigment cells from forming in mouse hair.

Defective T cell metabolism can cause early skin aging and poor hair follicle stem cell function.

Myotonic Dystrophy may age cells faster, and drugs that target aging could be potential treatments.
