[PMID: 38918590 PMCID: PMC11199485 DOI: 10.1038/s41598-024-65722-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2024] [Accepted: 06/24/2024] [Indexed: 06/27/2024] Open
Abstract
Contemporary treatment of vitiligo remains a great challenge to practitioners. The vast majority of currently conducted clinical trials of modern therapeutic methods are focused on systemic medications, while there is only a very limited number of reports on new topical treatment in vitiligo. With their pleiotropic activities statins turned out to be efficient in the treatment of various autoimmune/autoinflammatory disorders. The randomized, double-blind placebo-controlled study of topical administration of the active forms of simvastatin and atorvastatin has been designed to evaluate their efficacy in patients with vitiligo. The study was registered in clinicaltrials.gov (registration number NCT03247400, date of registration: 11th August 2017). A total of 24 patients with the active form of non-segmental vitiligo were enrolled in the study. The change of absolute area of skin lesions, body surface area and vitiligo area scoring index were evaluated throughout the 12 week application of ointments containing simvastatin and atorvastatin. Measurements were performed with planimetry and processed using digital software. Use of active forms of simvastatin and atorvastatin did not result in a significant repigmentation of the skin lesions throughout the study period. Within the limbs treated with topical simvastatin, inhibition of disease progression was significantly more frequent than in the case of placebo (p = 0.004), while the difference was not statistically significant for atorvastatin (p = 0.082). Further studies of topical simvastatin in vitiligo patients should be considered.

Abstract
This study aimed to develop atorvastatin-loaded emulgel and nano-emulgel dosage forms and investigate their efficiency on surgical wound healing and reducing post-operative pain. This double-blind randomized clinical trial was conducted in a surgical ward of a tertiary care hospital affiliated with university of medical sciences. The eligible patients were adults aged 18 years or older who were undergoing laparotomy. The participants were randomized in a 1:1:1 ratio to one of three following groups of atorvastatin-loaded emulgel 1% (n = 20), atorvastatin-loaded nano-emulgel 1% (n = 20), and placebo emulgel (n = 20) twice a day for 14 days. The primary outcome was the Redness, Edema, Ecchymosis, Discharge, and Approximation (REEDA) scores to determine the rate of wound healing. The Visual Analogue Scale (VAS) and quality of life were the secondary outcomes of this study. A total of 241 patients assessed for eligibility; of them, 60 patients completed the study and considered for final evaluation. A significant decrease in REEDA score was observed on Days 7 (63%) and 14 (93%) of treatment with atorvastatin nano-emulgel (p-value < 0.001). A significant decrease of 57% and 89% in REEDA score was reported at Days 7 and 14, respectively, in atorvastatin the emulgel group (p-value < 0.001). Reduction in pain VAS in the atorvastatin nano-emulgel was also recorded at Days 7 and 14 of the intervention. The results of the present study suggested that both topical atorvastatin-loaded emulgel and nano-emulgel 1% were effective in acceleration of wound healing and alleviation of pain of laparotomy surgical wounds, without causing intolerable side effects.

Abstract
Ulcerative colitis is a chronic inflammatory disease with high mortality and morbidity worldwide. It causes inflammation in the lining of the colon, resulting in several symptoms that negatively impact the quality of life. Unfortunately, there is currently no known cure for this condition. Therefore, it is crucial to explore alternative treatment approaches. This research aimed to investigate the anti-inflammatory and antioxidative effects of a combination therapy involving Sulfasalazine+Ezetimibe compared to Sulfasalazine alone in a rat model of ulcerative colitis. Forty adult rats were divided into four groups for this study. The groups consisted of a control group (negative control), an acetic acid group (positive control), an acetic acid+Sulfasalazine (100 mg/kg per day) group, and an acetic acid+Sulfasalazine (50 mg/kg)+Ezetimibe (5 mg/kg) group. Rats were treated for one week, and colitis was induced by administering 2 ml of 4% (v/v) acetic acid inter-rectally. After sacrifice, the colonic tissue homogenate was analyzed for several markers, including proinflammatory cytokines (TNF-α, IL-1β, NF-κB), oxidative stress markers (malondialdehyde, myeloperoxidase), and adhesive molecule markers (E-selectin, ICAM-1). Sulfasalazine and the combination of Sulfasalazine+Ezetimibe significantly reduced the colonic levels of TNF-α, IL-1β, NF-κB, MDA, and E-selectin in the homogenate. However, the combination therapy of Sulfasalazine and Ezetimibe demonstrated a superior effect.

Abstract
Background Kawasaki disease (KD) is a systemic vasculitis complicated with coronary artery abnormalities (CAAs). Intravenous immunoglobulin reduces the occurrence of CAAs, but significant number of KD patients with CAAs still exists. Thus, new approaches to prevent and attenuate CAAs are warranted. Atorvastatin has been shown to promote endothelial cell homeostasis and suppress vascular inflammation and has received enthusiasm as a potentially new candidate treatment for KD. In the United States, a phase I/IIa dose-escalation study of atorvastatin in KD patients with CAAs demonstrated the safety and pharmacokinetic data of atorvastatin. However, due to the uncertainty in the application of these results to other populations, we aim to examine the tolerability and generate pharmacokinetics data in Japanese KD patients. Methods This is a multicenter, single-arm, open-label, phase I/IIa study of atorvastatin in acute KD patients with CAAs in Japan. A minimum of 9 and a maximum of 18 KD patients (2 years–17 years old) will be recruited for a 3 + 3 dose-escalation study of a 6-week course of atorvastatin (0.125–0.5 mg/kg/day). The primary outcome will be safety of atorvastatin. The secondary outcomes will be pharmacokinetics of atorvastatin, activity of atorvastatin and echocardiographic assessment of CAAs. The activity of atorvastatin will include assessment of C-reactive protein or high sensitivity C-reactive protein and white blood cell levels. Discussion This study will provide evidence of the safety, tolerability, and pharmacokinetics of atorvastatin in Japanese KD patients and may lead new standard therapy for acute-phase KD associated with CAA complications.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Miconia albicans (Sw.) Triana has been widely used in Brazilian popular medicine for the treatment of several diseases. Aerial parts are used as an infusion to treat arthrosis and arthritis, to relieve rheumatic and stomach pains, and intestinal disorders due to its anti-inflammatory, anti-mutagenic anti-nociceptive, digestive and hepatoprotective properties. AIM OF THE STUDY This study aimed to characterize the of M. albicans (Sw.) Triana fruits extract (MAFRE) chemical profile and to evaluate its antioxidant, anti-inflammatory and antitumor activities, as well as its toxicity. MATERIALS AND METHODS Maceration with methanol as liquid extractor was used to prepare MAFRE. M. albicans (Sw.) Triana fruits chemical composition was characterized by UHPLC-QTOF-MS/MS and GC-FID (fatty acid methyl esters composition from lyophilized fruits). MAFRE antioxidant potential was evaluated in vitro using a combination of assays: Folin-Ciocalteu reducing capacity, DPPH• and ABTS radical scavenging ability and ferric reducing antioxidant power (FRAP). In vitro antiproliferative activity was investigated in four human tumor cell lines (U251, 786-0, HT29 and MDA-MB-231) while the effect on the non-tumor cell viability was assessed in the VERO cell line using the on-step MTT assay. In addition, in vivo anti-inflammatory effect was assessed by Croton oil-induced ear edema in mice followed by myeloperoxidase (MPO) activity evaluation. RESULTS Thirty-five compounds were identified by UHPLC-QTOF-MS/MS. Among it flavonoids derived from quercetin (8), myricetin (1), kaempferol (2), terpenoids (6) and other compounds (18). GC-FID analysis identified and quantified nine fatty acids: palmitic, stearic, arachidic, behenic, elaidic, oleic, eicosenoic, and linoleic acids. The most abundant fatty acids were polyunsaturated fatty acids (5.33 ± 0.17 mg g-1), followed by saturated fatty acids (2.38 ± 0.07 mg g-1) and monounsaturated fatty acids (1.74 ± 0.09 mg g-1). The extract revealed high content of phenolic compounds (43.68 ± 0.50 mg GAE/g of extract), potent antioxidant, and ferrous chelating capacities. Morever, it proved to be non-toxic to the VERO cells, not affecting cells viability (95% of viable cells). No antiproliferative effect against human tumor cell lines were found. Furthermore, MAFRE significantly (p<0.05) reduced ear edema (≈35%) and MPO activity (84.5%) having a statistical effect similar to traditional steroidal and non-steroidal anti-inflammatory drugs. CONCLUSIONS Taken together, the results evidenced that M. albicans fruit extract has antioxidant properties, a higher concentration of phenolic compounds, flavonoids, fatty acids, and also topical anti-inflammatory activity with low toxicity of extract on VERO cells. Through the ethnomedicinal study, these findings supporting the popular use of M. albicans, but also highlight that not only aerial parts and leaves deserve attention, but the fruits also have anti-inflammatory proprieties and can be a source of phenolic compounds and other substances with potential health benefices.

Abstract
The present study evaluated the anti-inflammatory effect of nanoencapsulated curcuminoid preparations of poly(vinyl pyrrolidone) (Nano-cur) and free curcuminoids (Cur) in an experimental model of croton oil-induced cutaneous inflammation. Male Swiss mice, weighing 25-30 g, received oral treatment by gavage 1 h before CO application or topical treatment immediately after CO application (200 μg diluted in 70% acetone) with a single dose of Cur and Nano-cur. After 6 h, the animals were anesthetized and euthanized. The ears were sectioned into disks (6.0 mm diameter) and used to determine edema, myeloperoxidase (MPO) activity, and oxidative stress. Photoacoustic spectroscopy (PAS) was used to evaluate the percutaneous penetration of Cur and Nano-cur. Topical treatment with both preparations had a similar inhibitory effect on the development of edema, MPO activity, and the oxidative response. The PAS technique showed that the percutaneous permeation of both topically applied preparations was similar. Oral Nano-cur administration exerted a higher anti-inflammatory effect than Cur. Topical Cur and Nano-cur application at the same dose similarly inhibited the inflammatory and oxidative responses. Oral Nano-cur administration inhibited such responses at doses that were eight times lower than Cur, suggesting the better bioavailability of Nano-cur compared with Cur.Graphical abstract.

Atorvastatin Solid Lipid Nanoparticles as a Promising Approach for Dermal Delivery and an Anti-inflammatory Agent. AAPS PharmSciTech 2020; 21:263. [PMID: 32978691 PMCID: PMC7519004 DOI: 10.1208/s12249-020-01807-9] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Accepted: 08/28/2020] [Indexed: 11/30/2022] Open
Abstract
In the current research, the main focus was to overcome dermal delivery problems of atorvastatin. To this end, atorvastatin solid lipid nanoparticles (ATR-SLNs) were prepared by ultra-sonication technique. The prepared SLNs had a PDI value of ≤ 0.5, and the particle size of nanoparticles was in the range 71.07 ± 1.72 to 202.07 ± 8.40 nm. It was noticed that, when the concentration of lipid in ATR-SLNs increased, the size of nanoparticles and drug entrapment efficiency were also increased. Results showed that a reduction in the HLB of surfactants used in the preparation of SLN caused an increase in the particle size, zeta potential (better stability), and drug entrapment efficiency. Despite Tween and Span are non-ionic surfactants, SLNs containing these surfactants showed a negative zeta potential, and the absolute zeta potential increased when the concentration of Span 80 was at maximum. DSC thermograms, FTIR spectra, and x-ray diffraction (PXRD) pattern showed good incorporation of ATR in the nanoparticles without any chemical interaction. In vitro skin permeation results showed that SLN containing atorvastatin was capable of enhancing the dermal delivery of atorvastatin where a higher concentration of atorvastatin can be detected in skin layers. This is a hopeful promise which could be developed for clinical studies of the dermal delivery of atorvastatin nanoparticles as an anti-inflammatory agent.

Abstract
Tissue repair and wound healing are complex processes that involve inflammation, granulation, and remodeling of the tissue. The potential of various statins including atorvastatin (ATR) to improve the wound healing effect was established. The aim of this study was to formulate and evaluate the efficacy of topical application of ATR-based nanoemulgel on wound healing. The prepared formulations (ATR gel, ATR emulgel, and ATR nanoemulgel) were evaluated for their physical appearance, rheological behavior, in vitro drug release and ex vivo drug permeation. The in vivo wound healing effect was evaluated in wound-induced rats. The prepared ATR gel formulations showed good physical properties and were comparable. The release profiles of drugs from gel, emulgel, and nanoemulgel were distinct. Skin permeation potential of ATR was significantly (p < 0.05) enhanced when formulated into nanoemulgel. In vivo wound healing studies showed that ATR nanoemulgel exhibited the highest percent wound contraction. Histopathological assessment showed marked improvement in the skin histological architecture after 21 days of ATR nanoemulgel treatment. In conclusion, the data demonstrated here signify the prospective of ATR nanoemulgel as an innovative therapeutic approach in wound healing.

Abstract
OBJECTIVES Open arterial revascularization using venous segments is frequently associated with the development of intimal hyperplasia (IH), leading to severe restenosis and graft failure. The lack of treatment to prevent this pathology is a major problem. Therefore, we generated a new porcine model, which closely mimics the clinical development of human IH, to test the therapeutic potential of candidate drugs. METHODS A patch of jugular vein was sutured to the right common carotid artery of pigs, to expose the vein to haemodynamic conditions of the arterial bed. Four weeks after surgery, the operated vessels which received no further treatment (the control group) were compared with (i) contralateral, non-operated vessels (the healthy group); (ii) vessels of pigs that received a perivascular application of a drug-free microparticle gel (the placebo group) and (iii) vessels of pigs that perioperatively received the same gel loaded with 10-mg atorvastatin (the atorvastatin group). RESULTS When compared with non-operated vessels, all operated segments displayed a sizable IH which was thicker in the venous patch than in the host artery. These alterations were associated with a thickening of the intima layer of both vessels in the absence of inflammation. The intima/media ratio has been significantly increased by 2000-fold in the vein patches. Perivascular application of atorvastatin did not prevent IH formation. However, the drug increased the adventitial neovascularization in the operated vessels. CONCLUSIONS The novel porcine model allows for monitoring IH formation under haemodynamic conditions which mimic clinical situations. It should facilitate the screening of innovative treatments to prevent restenosis.

Comparison of efficacy and safety of atorvastatin 5% lotion and betamethasone 0.1% lotion in the treatment of scalp seborrheic dermatitis. Clin Cosmet Investig Dermatol 2019; 12:267-275. [PMID: 31118730 PMCID: PMC6503294 DOI: 10.2147/ccid.s196412] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2018] [Accepted: 03/05/2019] [Indexed: 12/20/2022]
Abstract
Purpose: Seborrheic dermatitis (SD) is a chronic inflammatory skin disorder that mainly affects areas rich in sebaceous glands, such as the scalp. Although the exact cause of SD is not clearly understood, it seems that skin colonization with Malassezia fungus and the inflammatory responses of the immune system to this fungus play an important role in the pathology of SD. Recently a growing body of evidence has shown anti-inflammatory and anti-fungal effects of statins. Thus, this study aimed to evaluate the efficacy of topical atorvastatin in the treatment of scalp SD. Patients and methods: In this double-blind, clinical trial, 86 patients with mild-to-moderate scalp SD were divided into either atorvastatin (n=45) or betamethasone groups (n=41) by block randomization method. In addition to the ketoconazole 2% shampoo (3 times per week), the atorvastatin group received atorvastatin 5% lotion and the betamethasone group received betamethasone 0.1% lotion daily for 4 weeks. The SD severity of each patient was determined by Symptom Scale of Seborrheic Dermatitis (SSSD) at baseline and 4 weeks after treatment. Also, the patient’s satisfaction of the treatment and adverse effects were investigated through individual reporting. Results: After 4 weeks of treatment, the score of SD severity decreased significantly in both groups, while changes of SSSD score from baseline to the fourth week of treatment were comparable in the two groups (P-value=0.476). Regarding patient’s satisfaction of the treatment, results demonstrated the non-inferiority of atorvastatin as compared to betamethasone. Topical atorvastatin was also well-tolerated in almost all patients. Conclusion: Although preliminary, the results of the present study showed that topical atorvastatin has a comparable effect to topical betamethasone and can be considered as an alternative therapeutic modality in the treatment of scalp SD. However, these results need to be confirmed in future studies while taking into consideration the improvement of topical statin formulations.

Eur J Clin Pharmacol 2018; 75:171-178. [PMID: 30291370 DOI: 10.1007/s00228-018-2570-x] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2018] [Accepted: 09/28/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND PURPOSE The purpose of this randomized, placebo-controlled, double-blind study was to investigate the preventive effect of topical administration of atorvastatin (ATV) on the acute radiation-induced skin toxicity in patients with breast cancer. PATIENTS AND METHODS Seventy breast cancer patients were randomly assigned to use topical ATV 1% or placebo gels during radiotherapy twice daily. Radiation-induced dermatitis was classified according to the radiation therapy oncology group (RTOG) criteria, as well as pain and itching were scored according to VAS (visual analogue scale) for 6 weeks of treatment. RESULTS Topical administration of ATV gel during radiotherapy reduced significantly radiation-induced breast swelling, itching, and pain in breast cancer patients by factors of 1.8, 1.7, and 1.5, respectively. ATV reduced the redness caused by radiotherapy in patients as compared with placebo; however, this difference was statistically not significant. CONCLUSION ATV was able to reduce significantly itching, breast edema, and pain in patients during radiotherapy.

Abstract
PURPOSE To evaluate the expression of inflammatory mediators in xanthelasma palpebrarum. METHODS In this retrospective histopathologic case-control study, xanthelasma specimens obtained from the private practice and pathology archives of 1 author (R.Z.S.) were analyzed and compared with the blepharoplasty tissues from age- and sex-matched controls. Paraffin-embedded tissue sections were stained with hematoxylin-eosin and CD3, CD20, CD163, cyclooxygenase-1, inducible nitric oxide synthase, matrix metallopeptidase-9, and myeloperoxidase antibodies. Immunostaining was quantified by light microscopy and with a computerized image analysis system of scanned images. RESULTS Hematoxylin-eosin-stained preparations of xanthelasma specimens demonstrated significantly more intense chronic lymphocytic infiltrate when compared with the control blepharoplasty tissues (p < 0.001). Immunohistochemical studies revealed more intense CD3+ T cell and CD163+ histiocytic infiltrate (11% vs. 5%; p = 0.02 and 28% vs. 5%; p = 0.003, respectively) and increased expression of cyclooxygenase-1 (44% vs. 20% expressing cells; p < 0.001 and 21% vs. 9% strongly expressing cells; p = 0.008) and inducible nitric oxide synthase (43% vs. 26% expressing cells; p = 0.03 and 42% vs. 25% strongly expressing cells; p = 0.02) in xanthelasma specimens compared with control tissues. CONCLUSIONS The inflammatory milieu in xanthelasma appears to be analogous to descriptions of the early stages of cardiac atherosclerotic plaque formation. These findings may contribute to the understanding of xanthelasma pathogenesis and to the development of potential targeted therapies.

Abstract
OBJECTIVE The study aims to provide an overview of risk factors for hypertrophic scarring. BACKGROUND Hypertrophic skin scarring remains a major concern in medicine and causes considerable morbidity. Despite extensive research on this topic, the precise mechanism of excessive scarring is still unknown. In addition, the current literature lacks an overview of the possible risk factors in the development of hypertrophic scars. METHODS PubMed searches were performed on risk factors for hypertrophic scar (HTS) formation. RESULTS Eleven studies suggesting nine factors associated with HTS formation were found. Studies concerning chemotherapy, age, stretch, infection, and smoking have a moderate to high strength of evidence, but some other factors have not been studied in a convincing manner or are still disputed. CONCLUSIONS Risk factors for HTS formation are young age, bacterial colonization, and skin subjected to stretch. Chemotherapy, statins, and smoking seem to play a protective role in HTS formation.

Abstract
The objective of the present study was to investigate the effects of monotherapy with simvastatin or ezetimibe compared with those of an ezetimibe + simvastatin combination on the histopathologic aspects of arthritis induced by Complete Freund's Adjuvant in rats. The characteristics of diarthrosis were analyzed 7 and 28 days after arthritis induction with regard to the regularity and integrity of articular cartilage, the presence of leukocytes in blood vessels at the inflammation site, and the cytokine levels in articular tissue. Monotherapy with simvastatin or ezetimibe and the ezetimibe + simvastatin combination effectively reduced the cytokine levels (interleukin-6 and tumor necrosis factor) and articular lesions that are characteristic of this experimental disease. Although the results did not reveal significant differences between the monotherapy and the combined therapy, they suggest that these drugs have considerable antiinflammatory properties, as reflected by an attenuation of articular cartilage lesions mediated by a reduction in the levels of proinflammatory cytokines.

Abstract
Statins, widely used for treatment of hypercholesterolemia, have been demonstrated to exert pleiotropic beneficial effects independently of their cholesterol-lowering action, such as anti-inflammatory activity. A gender disparity has been observed in their cholesterol lowering activity as well as in response to these "off label" effects. Monocytes play a central role in atherosclerotic disease and, more in general, in inflammatory responses, through their chemotactic function and cytokine production. On these bases, in the present work, we examined the effect of statins on homeostasis and migration properties of freshly isolated monocytes from male and female healthy donors. Two prototypic natural and synthetic statins with different polarity, that is, type 1 and type 2 statins, have been considered: simvastatin and atorvastatin. Freshly isolated monocytes from peripheral blood of male and female healthy donors were treated with these drugs in the absence or presence of lipopolysaccharide (LPS) stimulation. Results obtained indicated that the polar statin efficiently inhibited chemotaxis of monocytes more than the apolar statin and that this effect was more significantly induced in cells from females than in cells from males. Dissecting the mechanisms involved, we found that these results could mainly be due to differential effects on: (i) the release of key cytokines, for example, MCP-1 and TNF-α; (ii) the maintenance of the redox homeostasis; (iii) a target activity on microfilament network integrity and function. All in all these results could suggest a reappraisal of "off-label" effects of statins taking into account either their chemical structure, that is, molecular polarity, or the gender issue.

Abstract
Atorvastatin is a 3-hydroxy-3-methylglutaryl coenzyme-A reductase inhibitor used in the treatment of atherosclerosis and dyslipidemia. Studies have evaluated the utility of statins in the treatment of skin inflammation but with varied results. In the present study, we investigated the effect of atorvastatin on TNF-α release and keratinocyte proliferation in vitro and in acute and chronic 12-O-tetradecanoylphorbol-13-acetate (TPA) induced skin inflammation in vivo. Atorvastatin significantly inhibited lipopolysacharide induced TNF-α release in THP-1 cells and keratinocyte proliferation in HaCaT cells. In an acute study, topical atorvastatin showed dose dependent reduction in TPA induced skin inflammation with highest efficacy observed at 500 µg/ear dose. In chronic study, topical atorvastatin significantly reduced TPA induced ear thickness, ear weight, cutaneous cytokines, MPO activity and improved histopathological features comparable to that of dexamethasone. Atorvastatin also inhibited TPA stimulated NF-κB activation in mouse ear. In conclusion, our results suggest that atorvastatin ameliorates TPA induced skin inflammation in mice at least in part, due to inhibition of cytokine release and NF-κB activation and may be beneficial for the treatment skin inflammation like psoriasis.

Abstract
Beare-Stevenson cutis gyrata syndrome (BSS) is a human genetic disorder characterized by skin and skull abnormalities. BSS is caused by mutations in the FGF receptor 2 (FGFR2), but the molecular mechanisms that induce skin and skull abnormalities are unclear. We developed a mouse model of BSS harboring a FGFR2 Y394C mutation and identified p38 MAPK as an important signaling pathway mediating these abnormalities. Fgfr2+/Y394C mice exhibited epidermal hyperplasia and premature closure of cranial sutures (craniosynostosis) due to abnormal cell proliferation and differentiation. We found ligand-independent phosphorylation of FGFR2 and activation of p38 signaling in mutant skin and calvarial tissues. Treating Fgfr2+/Y394C mice with a p38 kinase inhibitor attenuated skin abnormalities by reversing cell proliferation and differentiation to near normal levels. This study reveals the pleiotropic effects of the FGFR2 Y394C mutation evidenced by cutis gyrata, acanthosis nigricans, and craniosynostosis and provides a useful model for investigating the molecular mechanisms of skin and skull development. The demonstration of a pathogenic role for p38 activation may lead to the development of therapeutic strategies for BSS and related conditions, such as acanthosis nigricans or craniosynostosis.
