Alterations in Pattern Baldness According to Sex: Hair Metabolomics Approach. Metabolites 2021; 11:metabo11030178. [PMID: 33803764 PMCID: PMC8003215 DOI: 10.3390/metabo11030178] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Revised: 03/12/2021] [Accepted: 03/16/2021] [Indexed: 12/31/2022] Open
Abstract
Pattern baldness has been associated with the male hormone, dihydrotestosterone. In this study, we tried to determine how the overall metabolic pathways of pattern baldness differ in patients and in normal controls. Our study aimed to identify alterations in hair metabolomic profiles in order to identify possible markers of pattern baldness according to sex. Untargeted metabolomics profiling in pattern baldness patients and control subjects was conducted using ultra-performance liquid chromatography-mass spectrometry. To identify significantly altered metabolic pathways, partial least squares discriminant analysis was performed. Our analysis indicated differences in steroid biosynthesis pathway in both males and females. However, there was a remarkable difference in the androgen metabolic pathway in males, and the estrogen metabolic and arachidonic acid pathways in females. For the first time, we were able to confirm the metabolic pathway in pattern baldness patients using hair samples. Our finding improves understanding of pattern baldness and highlights the need to link pattern baldness and sex-related differences.

Abstract
No expression and distribution patterns of polyamines (PAs), spermine, spermidine, and their precursor putrescine in mammalian hair follicle are available, although polyamines are known to correlate well with hair growth and epidermal tumor genesis. Immunohistochemistry (IHC) using our original two monoclonal antibodies (mAbs) ASPM-29 specific for spermine or spermidine, and APUT-32 specific for putrescine allowed us to detect immunoreactivity for polyamines in hair follicles from normal adult rats. A wide range of immunoreactivity for the total spermine and spermidine was observed in the compartments of hair follicle: The highest degree of immunoreactivity for polyamines was observed in the matrix, in the Huxley's layer, in the deeper Henle's layer, and in the cuticle of the inner root sheath/the hair cuticle, while moderate immunoreactivity existed in the lower-to-mid cortex and the companion layer, followed by lower immunoreactivity in the outer root sheath, including the bulge region and in the deeper medulla, in which the immunoreactivity was also evident in their nuclei. In addition, somewhat surprisingly, with IHC by APUT-32 mAb, we detected significant levels of putrescine in the compartments, in which the immunostaining pattern was the closely similar to that of the total spermine and spermidine. Thus, among these compartments, the cell types of the matrix, the Huxley's layer, the deeper Henle's layer, and the cuticle of the inner root sheath/the hair cuticle seem to have the biologically higher potential in compartments of anagen hair follicle, maybe suggesting that they are involved more critically in the biological event of hair growth. In addition, we noted sharp differences of immunostaining by IHCs between ASPM-29 mAb and APUT-32 mAb in the epidermis cells and fibroblast. ASPM-29 mAb resulted in strong staining in both the cell types, but APUT-32 mAb showed only very light staining in both types. Consequently, the use of the two IHCs could be extremely useful in further studies on hair cycle and epidermal tumor genesis experimentally or clinically.

Abstract
Polyamines are cationic amines essential for cellular proliferation. Recently, their role in hair follicle (HF) growth has started to be explored, but their exact function is still obscure. In the October issue of Experimental Dermatology, Luke et al. follow the observation that putrescine overproducing mice and hairless (HR) mutant mice show a similar clinical phenotype of hair loss and dermal cyst formation. They show that HR and putrescine form a negative regulatory feedback mechanism, which might regulate hair cycling and therefore control hair growth. This study clearly demonstrates that a strong connection exists between HR and polyamines although there are probably additional molecular pathways involved in the polyamine regulation of hair growth which remain to be discovered.

Abstract
Hairless (HR) is a nuclear protein with corepressor activity that is highly expressed in the skin and hair follicle. Mutations in Hairless lead to hair loss accompanied by the appearance of papules (atrichia with papular lesions), and similar phenotypes appear when the key polyamine enzymes ornithine decarboxylase (ODC) and spermidine/spermine N(1) -acetyltransferase (SSAT) are overexpressed. Both ODC and SSAT transgenic mice have elevated epidermal levels of putrescine, leading us to investigate the mechanistic link between putrescine and HR. We show here that HR and putrescine form a negative regulatory network, as epidermal ODC expression is elevated when HR is decreased and vice versa. We also show that the regulation of ODC by HR is dependent on the MYC superfamily of proteins, in particular MYC, MXI1 and MXD3. Furthermore, we found that elevated levels of putrescine lead to decreased HR expression, but that the SSAT-TG phenotype is distinct from that found when HR is mutated. Transcriptional microarray analysis of putrescine-treated primary human keratinocytes demonstrated differential regulation of genes involved in protein-protein interactions, nucleotide binding and transcription factor activity, suggesting that the putrescine-HR negative regulatory loop may have a large impact on epidermal homeostasis and hair follicle cycling.

Abstract
Over-expression of ornithine decarboxylase (ODC) is known to be involved in the epidermal carcinogenesis. However, the mechanism by which it enhances skin carcinogenesis remains undefined. Recently, role of stem cells localized in various epidermal compartments has been shown in the pathogenesis of skin cancer. To direct ODC expression in distinct epidermal compartments, we have developed keratin 6 (K6)-ODC/SKH-1 and keratin 14 (K14)-ODC/SKH-1 mice and employed them to investigate the role of ODC directed to these epidermal compartments on UVB-induced carcinogenesis. K6-driven ODC over-expression directed to outer root sheath (ORS) of hair follicle was more effective in augmenting tumorigenesis as compared to mice where K14-driven ODC expression was directed to inter-follicular epidermal keratinocytes. Chronically UVB-irradiated K6-ODC/SKH-1 developed 15±2.5 tumors/mouse whereas K14-ODC/SKH-1 developed only 6.8±1.5 tumors/mouse. K6-ODC/SKH-1 showed augmented UVB-induced proliferation and much higher pro-inflammatory responses than K14-ODC/SKH-1 mice. Tumors induced in K6-ODC/SKH-1 were rapidly growing, invasive and ulcerative squamous cell carcinoma (SCC) showing decreased expression of epidermal polarity marker E-cadherin and enhanced mesenchymal marker, fibronectin. Interestingly, the number of CD34/CK15/p63 positive stem-like cells was significantly higher in chronically UVB-irradiated K6-ODC/SKH-1 as compared to K14-ODC/SKH-1 mice. Reduced Notch1 expression was correlated with the expansion of stem cell compartment in these animals. However, other signaling pathways such as DNA damage response or mTOR signaling pathways were not significantly different in tumors induced in these two murine models suggesting the specificity of Notch pathway in this regard. These data provide a novel role of ODC in augmenting tumorigenesis via negatively regulated Notch-mediated expansion of stem cell compartment.

Abstract
BACKGROUND Rapidly regenerating tissues need sufficient polyamine synthesis. Since the hair follicle (HF) is a highly proliferative mini-organ, polyamines may also be important for normal hair growth. However, the role of polyamines in human HF biology and their effect on HF epithelial stem cells in situ remains largely unknown. METHODS AND FINDINGS We have studied the effects of the prototypic polyamine, spermidine (0.1-1 µM), on human scalp HFs and human HF epithelial stem cells in serum-free organ culture. Under these conditions, spermidine promoted hair shaft elongation and prolonged hair growth (anagen). Spermidine also upregulated expression of the epithelial stem cell-associated keratins K15 and K19, and dose-dependently modulated K15 promoter activity in situ and the colony forming efficiency, proliferation and K15 expression of isolated human K15-GFP+ cells in vitro. Inhibiting the rate-limiting enzyme of polyamine synthesis, ornithine decarboyxlase (ODC), downregulated intrafollicular K15 expression. In primary human epidermal keratinocytes, spermidine slightly promoted entry into the S/G2-M phases of the cell cycle. By microarray analysis of human HF mRNA extracts, spermidine upregulated several key target genes implicated e.g. in the control of cell adherence and migration (POP3), or endoplasmic reticulum and mitochondrial functions (SYVN1, NACA and SLC25A3). Excess spermidine may restrict further intrafollicular polyamine synthesis by inhibiting ODC gene and protein expression in the HF's companion layer in situ. CONCLUSIONS These physiologically and clinically relevant data provide the first direct evidence that spermidine is a potent stimulator of human hair growth and a previously unknown modulator of human epithelial stem cell biology.

Abstract
Polyamines (spermidine, putrescine and spermine) are multifunctional cationic amines that are indispensable for cellular proliferation; of key significance in the growth of rapidly regenerating tissues and tumors. Given that the hair follicle (HF) is one of the most highly proliferative organs in mammalian biology, it is not surprising that polyamines are crucial to HF growth. Indeed, growing (anagen) HFs show the highest activity of ornithine decarboxylase (ODC), the rate-limiting enzyme of polyamine biosynthesis, while inhibition of ODC, using eflornithine, results in a decreased rate of excessive facial hair growth in vivo and inhibits human scalp hair growth in organ culture. In sheep, manipulation of dietary intake of polyamines also results in altered wool growth. Polyamine-containing nutraceuticals have therefore been proposed as promoters of human hair growth. Recent progress in polyamine research, coupled with renewed interest in the role of polyamines in skin biology, encourages one to revisit their potential roles in HF biology and highlights the need for a systematic evaluation of their mechanisms of action and clinical applications in the treatment of hair disorders. The present viewpoint essay outlines the key frontiers in polyamine-related hair research and defines the major open questions. Moreover, it argues that a renaissance in polyamine research in hair biology, well beyond the inhibition of ODC activity in hirsutism therapy, is important for the development of novel therapeutic strategies for the manipulation of human hair growth. Such targets could include the manipulation of polyamine biosynthesis and the topical administration of selected polyamines, such as spermidine.

Abstract
BACKGROUND Hirsutism is the presence of excess body or facial terminal (coarse) hair growth in females in a male-like pattern, affects 5-15% of women, and is an important sign of underlying androgen excess. Different methods are available for the assessment of hair growth in women. METHODS We conducted a literature search and analyzed the published studies that reported methods for the assessment of hair growth. We review the basic physiology of hair growth, the development of methods for visually quantifying hair growth, the comparison of these methods with objective measurements of hair growth, how hirsutism may be defined using a visual scoring method, the influence of race and ethnicity on hirsutism, and the impact of hirsutism in diagnosing androgen excess and polycystic ovary syndrome. RESULTS Objective methods for the assessment of hair growth including photographic evaluations and microscopic measurements are available but these techniques have limitations for clinical use, including a significant degree of complexity and a high cost. Alternatively, methods for visually scoring or quantifying the amount of terminal body and facial hair growth have been in use since the early 1920s; these methods are semi-quantitative at best and subject to significant inter-observer variability. The most common visual method of scoring the extent of body and facial terminal hair growth in use today is based on a modification of the method originally described by Ferriman and Gallwey in 1961 (i.e. the mFG method). CONCLUSION Overall, the mFG scoring method is a useful visual instrument for assessing excess terminal hair growth, and the presence of hirsutism, in women.

Abstract
The polyamines are important regulators of cell growth and differentiation. Cells acquire polyamines by energy-dependent transport and by synthesis where the highly regulated ornithine decarboxylase (ODC) catalyzes the first and rate-controlling step. Inactivation of ODC is mainly exerted by antizyme (AZ), a 20--25 kDa polyamine-induced protein that binds to ODC, inactivates it, and targets it for degradation by the 26S proteasome without ubiquitination. In the present study, we have performed a systematic analysis of the expression of ODC and AZ, at the mRNA and protein levels, during mouse development. The expression patterns for ODC and AZ were found to be developmentally regulated, suggesting important functions for the polyamines in early embryogenesis, axonogenesis, epithelial-mesenchymal interaction, and in apoptosis. In addition, AZ protein was found to translocate to the nucleus in a developmentally regulated manner. The nuclear localization is consistent with the fact that the amino acid sequence of AZ exhibits features that characterize nuclear proteins. Interestingly, we found that cultivation of mandibular components of the first branchial arch in the presence of a selective proteasome inhibitor caused ODC accumulation in the nucleus of a subset of cells, suggesting that the observed nuclear translocation of AZ is linked to proteasome-mediated ODC degradation in the nucleus. The presence of AZ in the nucleus may suggest that nuclear ODC activity is under tight control, and that polyamine production can be rapidly interrupted when those developmental events, which depend on access to nuclear polyamines, have been completed.
