Sintos AML, Cabrera HS. Network Pharmacology Reveals Curcuma aeruginosa Roxb. Regulates MAPK and HIF-1 Pathways to Treat Androgenetic Alopecia. BIOLOGY 2024; 13:497. [PMID: 39056691 PMCID: PMC11274231 DOI: 10.3390/biology13070497] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/01/2024] [Revised: 06/20/2024] [Accepted: 06/26/2024] [Indexed: 07/28/2024]
Abstract
Androgenetic alopecia (AGA) is the most prevalent hair loss disorder worldwide, driven by excessive sensitivity or response to androgen. Herbal extracts, such as Curcuma aeruginosa Roxb., have shown promise in AGA treatment due to their anti-androgenic activities and hair growth effects. However, the precise mechanism of action remains unclear. Hence, this study aims to elucidate the active compounds, putative targets, and underlying mechanisms of C. aeruginosa for the therapy of AGA using network pharmacology and molecular docking. This study identified 66 bioactive compounds from C. aeruginosa, targeting 59 proteins associated with AGA. Eight hub genes were identified from the protein-protein interaction network, namely, CASP3, AKT1, AR, IL6, PPARG, STAT3, HIF1A, and MAPK3. Topological analysis of components-targets network revealed trans-verbenol, myrtenal, carvone, alpha-atlantone, and isoaromandendrene epoxide as the core components with potential significance in AGA treatment. The molecular docking verified the binding affinity between the hub genes and core compounds. Moreover, the enrichment analyses showed that C. aeruginosa is involved in hormone response and participates in HIF-1 and MAPK pathways to treat AGA. Overall, this study contributes to understanding the potential anti-AGA mechanism of C. aeruginosa by highlighting its multi-component interactions with several targets involved in AGA pathogenesis.

Deletion of hypoxia-inducible factor prolyl 4-hydroxylase 2 in FoxD1-lineage mesenchymal cells leads to congenital truncal alopecia. J Biol Chem 2022; 298:101787. [PMID: 35247391 PMCID: PMC8988008 DOI: 10.1016/j.jbc.2022.101787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Revised: 02/03/2022] [Accepted: 02/04/2022] [Indexed: 11/22/2022] Open
Abstract
Hypoxia-inducible factors (HIFs) induce numerous genes regulating oxygen homeostasis. As oxygen sensors of the cells, the HIF prolyl 4-hydroxylases (HIF-P4Hs) regulate the stability of HIFs in an oxygen-dependent manner. During hair follicle (HF) morphogenesis and cycling, the location of dermal papilla (DP) alternates between the dermis and hypodermis and results in varying oxygen levels for the DP cells. These cells are known to express hypoxia-inducible genes, but the role of the hypoxia response pathway in HF development and homeostasis has not been studied. Using conditional gene targeting and analysis of hair morphogenesis, we show here that lack of Hif-p4h-2 in Forkhead box D1 (FoxD1)-lineage mesodermal cells interferes with the normal HF development in mice. FoxD1-lineage cells were found to be mainly mesenchymal cells located in the dermis of truncal skin, including those cells composing the DP of HFs. We found that upon Hif-p4h-2 inactivation, HF development was disturbed during the first catagen leading to formation of epithelial-lined HF cysts filled by unorganized keratins, which eventually manifested as truncal alopecia. Furthermore, the depletion of Hif-p4h-2 led to HIF stabilization and dysregulation of multiple genes involved in keratin formation, HF differentiation, and HIF, transforming growth factor β (TGF-β), and Notch signaling. We hypothesize that the failure of HF cycling is likely to be mechanistically caused by disruption of the interplay of the HIF, TGF-β, and Notch pathways. In summary, we show here for the first time that HIF-P4H-2 function in FoxD1-lineage cells is essential for the normal development and homeostasis of HFs.

Life Sci 2017; 191:82-89. [PMID: 29030089 DOI: 10.1016/j.lfs.2017.10.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2017] [Revised: 09/15/2017] [Accepted: 10/09/2017] [Indexed: 12/22/2022]
Abstract
AIMS Outer root sheath (ORS) is a highly proliferative component of a hair follicle. This study is performed to investigate whether hypoxia-induced elevation of hypoxia-inducible factor (HIF)-1α, a transcriptional activator, contributes to the outgrowth of ORS cells in vitro. MAIN METHODS Hair follicles with intact ORS collected from 4-month old male American minks were cultured in normoxic or hypoxic condition (3% oxygen) for 7days. Primary ORS cells isolated from the mink hair follicles were exposed to hypoxia for 12, 24 or 48h, and their proliferation was analyzed with immunofluorescence assay using anti-proliferating cell nuclear antigen (PCNA) antibody. The migratory ability of ORS cells was detected via the transwell chamber. The endogenous HIF-1α was knocked down with its specific siRNA in ORS cells. KEY FINDINGS Hypoxic exposure induced an elevation of HIF-1α in ex vivo cultured hair follicles. The mRNA and protein levels of sonic hedgehog (Shh), Shh receptor Patched 1, Smoothened and glioma-associated oncogene homologue 1 were upregulated. In vitro, hypoxia induced an increase in HIF-1α in ORS cells. Further, under hypoxic condition, the number of PCNA-positive cells was increased, and more cells migrated towards high serum media. Hypoxia-enhanced proliferation and migration of ORS cells were suppressed either by HIF-1α siRNA or by pharmacological inhibitors of Shh pathway, cyclopamine and GANT61. The activation of Shh pathway was attenuated in HIF-1α-silenced ORS cells under hypoxic condition. SIGNIFICANCE Our work demonstrates a direct role of activated HIF-1/Shh biological axis in sustaining the development of ORS in vitro.

THE AMERICAN JOURNAL OF PATHOLOGY 2016; 186:1036-43. [PMID: 26873447 DOI: 10.1016/j.ajpath.2015.12.013] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/18/2015] [Revised: 11/25/2015] [Accepted: 12/07/2015] [Indexed: 12/27/2022]
Abstract
OVOL1 and OVOL2, ubiquitously conserved genes encoding C2H2 zinc finger transcription factors in mammals, control epithelial cell proliferation, and differentiation, including those in skin. OVOL1 and OVOL2 expression is coordinately mediated via the Wnt signaling pathway, and OVOL1 negatively regulates OVOL2 expression in a transcriptional manner. Our previous study of OVOL1 expression in human skin revealed that OVOL1 is preferentially expressed in the inner root sheath of the hair follicle. Therefore, we hypothesized that the OVOL1-OVOL2 axis is involved in normal and neoplastic follicular differentiation. Immunohistochemical analysis showed that OVOL1 and OVOL2 were strongly expressed in a mutually exclusive manner in the cytoplasm of inner root sheath cells and matrix cells, respectively, in normal follicles. OVOL2 was also expressed in pilomatricoma, with only partial expression of OVOL1. Cultured human keratinocytes expressed OVOL1 and OVOL2 on both the mRNA and protein levels. The expression of OVOL2 was higher in keratinocytes transfected with siRNA of OVOL1. Ketoconazole, a hair growth stimulant, up-regulated the expression of OVOL1 but did not affect OVOL2 expression. These results indicated that the OVOL1-OVOL2 axis may actively contribute to cell differentiation and proliferation in the hair bulb, suggesting that the OVOL1 and OVOL2 may be therapeutic targets of hair disorders, including alopecia, and play important roles in the tumorigenesis of pilomatricoma.
