Three major food classes that promote acne are: 1) hyperglycemic carbohydrates, 2) milk and dairy products, 3) saturated fats including trans- fats and deficient . Diet- induced insulin/insulin- like growth factor (IGF- 1)- signaling is superimposed on elevated IGF- 1 levels during puberty, thereby unmasking the impact of aberrant nutrigenomics on sebaceous gland homeostasis. Western diet provides abundant branched- chain amino acids (BCAAs), glutamine, and palmitic acid. Insulin and IGF- 1 suppress the activity of the metabolic transcription factor forkhead box O1 (Fox. O1). Insulin, IGF- 1, BCAAs, glutamine, and palmitate activate the nutrient- sensitive kinase mechanistic target of rapamycin complex 1 (m. TORC1), the key regulator of anabolism and lipogenesis. Fox. O1 is a negative coregulator of androgen receptor, peroxisome proliferator- activated receptor- . SREBP- 1c upregulates stearoyl- Co. A- and . Diet- mediated aberrations in sebum quantity (hyperseborrhea) and composition (dysseborrhea) promote Propionibacterium acnes overgrowth and biofilm formation with overexpression of the virulence factor triglyceride lipase increasing follicular levels of free palmitate and oleate. Free palmitate functions as a “danger signal,” stimulating toll- like receptor- 2- mediated inflammasome activation with interleukin- 1. Oleate stimulates P. Thus, diet- induced metabolomic alterations promote the visible sebofollicular inflammasomopathy acne vulgaris. Nutrition therapy of acne has to increase Fox. O1 and to attenuate m. TORC1/SREBP- 1c signaling. Patients should balance total calorie uptake and restrict refined carbohydrates, milk, dairy protein supplements, saturated fats, and trans- fats. A paleolithic- like diet enriched in vegetables and fish is recommended. Plant- derived m. TORC1 inhibitors and . The first part links Western diet to disturbed sebaceous lipogenesis promoted by systemic aberrations of endocrine signaling. To understand the role of nutrigenomics in the pathogenesis of acne, two central players will be highlighted: the role of the metabolic transcription factor forkhead box O1. A (Fox. O1),1–4 and the nutrient- sensitive kinase mechanistic target of rapamycin complex 1 (m. TORC1). 5–8 The second part explains the molecular link between disturbed sebofollicular metabolomics and inflammation. The reader will understand that Western diet is the major factor overstimulating sebum production, Propionibacterium acnes overgrowth, and biofilm formation. Biofilm- transformed P. Abundance of sebum- derived free palmitate together with P. There is no doubt that androgen excess promotes acne and seborrhea, whereas acne does not develop under conditions of androgen receptor (AR) loss of function leading to androgen insensitivity. These facts clearly point to the involvement of AR- dependent signaling in the pathogenesis of acne. Yet there is still an unsolved contradiction: it is well established that androgen serum levels increase during puberty and stay at high levels for decades, whereas acne physiologically fades spontaneously after puberty. After the climax of puberty, serum levels of insulin- like growth factor 1 (IGF- 1), the major growth hormone of puberty, decrease continuously. Deplewski and Rosenfield. IGF- 1 levels correlate with the clinical manifestation of acne. Evidence will be presented that not androgens but IGF- 1 plays the primary role in acne pathogenesis. IGF- 1 signaling is the central endocrine pathway of puberty and sexual maturation, and is the converging point of nutrient signaling in acne. Which facts do prove this change of paradigms? There is a human experiment of nature supporting the primary role of IGF- 1 signaling in acne pathogenesis, the Laron syndrome. Short- statured individuals with Laron syndrome exhibit a congenital IGF- 1 deficiency due to growth hormone receptor (GHR) mutations. Notably, Laron patients, who are not treated with recombinant IGF- 1, never develop acne or other common diseases of Western civilization. However, high- dose IGF- 1 administration induces acne and hyperandrogenism in these GHR- deficient patients. The occurrence of hyperandrogenism in IGF- 1- treated Laron patients already implies that IGF- 1 enhances AR- dependent signal transduction. IGF- 1 inhibits Fox. O1 signaling at multiple regulatory layers. IGF- 1 promotes cell growth and cell proliferation by activating the IGF- 1 receptor (IGF1. R), resulting in upregulation of the phosphoinositol- 3- kinase (PI3. K)–protein kinase B (AKT) signaling cascade. Pioneering autoradiographic studies of Plewig et al. In acne, increased cell proliferation has been demonstrated in keratinocytes of the acroinfundibulum and ductus seboglandularis, and sebocytes of the sebaceous gland. Thus, the question arose as to how IGF- 1 increases local proliferation of acroinfundibular keratinocytes, epithelial cells of the ductus seboglandularis, and sebocytes. To understand the stimulatory effects of IGF- 1 on sebofollicular androgen signaling, it is of critical importance to become familiar with the major regulatory mechanisms that enhance AR transcriptional activity. The AR is a nuclear transcription factor that stimulates the expression of genes that promote androgen- dependent growth and proliferation. AR activation requires two major stimuli: 1) binding of its hormone ligand (androgen), and 2) derepression of its inhibitory nuclear coregulator Fox. O1. Ligand- mediated activation of AR depends on androgen binding affinity. Highest AR binding affinity exhibits dihydrotestosterone (DHT), which is ten times higher compared with testosterone. IGF- 1 is a potent inducer of gonadal testosterone and adrenal dehydroepiandrosterone (DHEA) synthesis and promotes the intracutaneous conversion of testosterone to DHT by enhancing 5. Conversely, the androgens induce IGF- 1 in the hair follicle. Thus, IGF- 1 stimulates AR signal transduction by upregulating the amount and affinity of AR- activating ligands. Most dermatologists are not aware of the second most important IGF- 1- dependent mechanism that increases AR signaling that involves the metabolic transcription factor Fox. O1. In the nucleus, Fox. O1 functions as an AR cosuppressor. Nuclear Fox. O1 levels are negatively regulated by insulin and IGF- 1. Both sister hormones activate the PI3. K–AKT pathway. 2. Activated AKT phosphorylates Fox. O1 in the nucleus, which is the critical step promoting its translocation into the cytoplasm. Fox. O1 suppresses AR transactivation by binding to the transcription activation unit 5 (TAU5) located in the AR N- terminal domain (NTD). The TAU5 motif is most important for androgen- independent activation of the AR,3. IGF- 1- mediated activation of AKT, and is thus connected to the nutrient status. Taken together, AR activation requires two different IGF- 1- dependent pathways: 1) enhanced ligand potentiation and ligand binding to the AR ligand binding domain and 2) activation of AR transactivation by the nuclear extrusion of the AR suppressor Fox. O1 from the NTD. Notably, the NTD contains a polyglutamine- enriched region encoded by CAG trinucleotide repeats. Expansion of these CAG repeats in the AR reduces AR activation, whereas AR polymorphisms featuring shorter CAG repeats are associated with androgenetic alopecia, hirsutism, and acne. Individuals featuring AR polymorphisms with shorter CAG repeats in comparison with individuals with normal CAG repeat length apparently exhibit easier AR hyperactivation by insulin/IGF- 1 signaling. These insights also explain increased AR signaling in states of hyperinsulinemia and insulin resistance and conditions with increased IGF- 1 serum levels such as puberty and nutrient signaling of Western diet. Individuals with shorter CAG repeats may thus exhibit stronger acneigenic reactions by dietary exposure to a high glycemic load diet and milk consumption, which both enhance insulin/IGF- 1 signaling. My hypothesis of aberrant IGF- 1/Fox. O1 signaling in the pathogenesis of acne has recently been confirmed experimentally in SZ9. Prolonged IGF- 1 exposure of SZ9. Fox. O1 into sebocyte’s cytoplasm. Thus, the transcriptional coordinator of metabolism Fox. O1 links insulin/IGF- 1 signaling to transcriptional activation of AR- dependent target genes. Notably, the highest nuclear Fox. O1 activity is observed during starvation, whereas nutrient excess leads to reduced nuclear levels of Fox. O1. 3,3. 6,3. 7Serum levels of DHEA, the major adrenal androgen that increases during adrenarche, correlate with the onset of acne vulgaris. Notably, DHEA induces ERK1/2- mediated phosphorylation and translocation of Fox. O1. 3. 9 Thus, increased adrenal DHEA signaling, which begins prior to puberty, already suppresses Fox. O1 activity, increasing AR transactivation. DHEA- induced inactivation of Fox. O1 may also explain neonatal hyperseborrhea and acne due to excessive fetal DHEA production, a physiological mechanism ensuring the generation of the vernix caseosa, which is important for birth. Nuclear Fox. O1, which is upregulated by isotretinoin treatment,4. Fox. O1 was recently reported to be an inhibitor of follicle stimulating hormone and luteinizing hormone production.
