Proper care and diet are crucial to prevent health issues in gerbils.

The project created a standardized system for classifying skin lesions in lab rats and mice.

A rare benign skin tumor showed unusual features of sebaceous and sweat glands, important for correct diagnosis.

Some skin tumors from hair follicles and glands can be linked to genetic syndromes and may be benign or malignant.

Genetic changes in mice help understand skin and hair disorders, aiding treatment development for acne and hair loss.

Adam10 enzyme is crucial for healthy skin and proper Notch signaling.

Hormones, especially androgens, play a key role in acne, which can be a symptom of systemic diseases like PCOS and may require targeted treatment.
