research Promotion of homology-directed DNA repair by polyamines
Polyamines help fix DNA damage accurately in cells.
research Sex steroid synthesis in human skin in situ: The roles of aromatase and steroidogenic acute regulatory protein in the homeostasis of human skin
Human skin produces sex hormones like estrogen and testosterone, influenced by ARO and StAR, which may affect skin elasticity and hair growth.
research Hair Growth Defects in Insig-Deficient Mice Caused by Cholesterol Precursor Accumulation and Reversed by Simvastatin
Mice lacking Insig proteins had hair growth problems due to cholesterol buildup, but this was fixed by the drug simvastatin.
research Rosmarinus officinalis L. (Rosemary) Extracts Containing Carnosic Acid and Carnosol are Potent Quorum Sensing Inhibitors of Staphylococcus aureus Virulence
Rosemary extracts with carnosic acid and carnosol can reduce the harmfulness of Staphylococcus aureus without stopping its growth.
