Effects of Seed Oil on Cultured Human Sebocytes In Vitro and Comparison with Other Oil Types.

The seeds of (horseradish tree) contain about 40% of one of the most stable vegetable oils (Moringa seed oil). Therefore, the effects of Moringa seed oil on human SZ95 sebocytes were investigated and were compared with other vegetable oils. Immortalized human SZ95 sebocytes were treated with Moringa seed oil, olive oil, sunflower oil, linoleic acid and oleic acid.

Free Fatty Acids Induce Lipid Accumulation, Autophagy, and Apoptosis in Human Sebocytes.

Background: A disruption of sebocyte differentiation and lipogenesis has fatal consequences and can cause a wide spectrum of skin diseases, from acne vulgaris to sebaceous carcinoma, however, the relevant molecular mechanisms have not been fully clarified.

Objectives: The induction of autophagy and apoptosis in human sebocytes in response to biologically relevant fatty acids was investigated.

Methods: Free fatty acids (arachidonic acid, linoleic acid, palmitic acid, and palmitoleic acid) and the pan-caspase inhibitor QVD-Oph were added to the supernatant of cultured human SZ95 sebocytes.

Skin Mirrors Brain: A Chance for Alzheimer's Disease Research.

The accessibility of skin and the easy isolation of its cells and matrix components provide a valuable tool for studying the molecular factors involved in human aging. Moreover, increasing evidence corroborates the use of the skin as a model for age-associated pathological conditions in the entire body. Apparently based on the fact that the nervous system and skin share a common ectodermal origin, certain genes and molecular pathways associated with the pathomechanism of neurodegenerative diseases modify their expression with progressing skin aging.

Metabolic Disorders/Obesity Is a Primary Risk Factor in Hidradenitis Suppurativa: An Immunohistochemical Real-World Approach.

Background: Hidradenitis suppurativa (HS) is an inflammatory, potentially scarring disease of the hair follicle, affecting the apocrine gland-bearing skin areas. The major comorbid disorders associated with the occurrence or the aggravation of the disease are obesity and smoking. Numerous efforts to dissociate these factors led to controversial results.
