Plasma Cytokines for the Prediction of the Effectiveness of TNFα Inhibitors Etanercept, Infliximab, and Adalimumab in the Treatment of Psoriasis. J Clin Med 2024; 13:3895. [PMID: 38999459 PMCID: PMC11242498 DOI: 10.3390/jcm13133895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 05/08/2024] [Accepted: 05/19/2024] [Indexed: 07/14/2024] Open
Abstract
Background/Objectives: Psoriasis is a chronic, inflammatory, immuno-mediated cutaneous disease characterized by a prominent TNFα-IL23/IL17 immune axis. In recent years, targeted therapies have become standard practice for managing moderate-to-severe psoriasis and have demonstrated efficacy. At the same time, identifying factors associated with the success or failure of TNFα inhibitor therapy remains one of the most difficult aspects in psoriasis treatment. Methods: A clinical, non-randomized study was conducted to evaluate the impact of TNFα inhibitors on the plasma cytokine profiles in patients with moderate-to-severe psoriasis vulgaris (ICD-10 code L40.0). The patients were treated with either etanercept, adalimumab, or infliximab for 16 weeks. Plasma cytokine profiles were assessed using a BioPlex200 System. Results: By the 16th week of therapy, a positive treatment response (PASI ≥ 75) was observed in 51 patients (63%), while 30 patients (37%) showed no response (PASI ≤ 50). When using etanercept, a positive effect was observed in 11 patients (41%), in 14 patients (52%) using adalimumab, and in 26 patients (96%) using infliximab. Analysis of the baseline cytokine levels revealed no differences between the "positive effect" and "no effect" groups, except for IL20, which was 2.61 times higher in the "positive effect" group compared to the "no effect" group, suggesting its potential predictive role in the effectiveness of therapy with TNFα inhibitors. Treatment led to a decrease in IL17F, IL31, sCD40L, and VEGF for all patients, and in IL20 for the "positive effect" group. The increase in ICAM1 in the "no effect" group suggests the possible retention of active migration and the fixation of T cells in the affected skin in these patients. No significant difference in cytokine levels was observed when categorizing patients into subgroups based on the effectiveness of therapy with etanercept, infliximab, and adalimumab; only a pre- and post-treatment difference in the whole cohort was noted. A random forest model showed the importance of VEGF, sCD40L, and ICAM1. Conclusions: The baseline levels of VEGF, sCD40L, and ICAM1, as well as IL20, could serve as potential predictors of treatment effectiveness using TNFa inhibitors. However, this hypothesis requires confirmation with a larger patient population.

Abstract
Background Psoriasis is a global health concern as a chronic inflammatory skin disease. Endothelial dysfunction has been implicated in psoriasis pathogenesis. Objective This study aims to explore the scientific literature on the relationship between psoriasis and endothelial cells using bibliometric analysis, identifying research trends and public interest in this topic. Methods We analyzed articles on the topic of endothelial cells and psoriasis in the Web of Science (WoS) Core Collection from 1987 to 2022, examining their distribution by publication year, country, organization, author, and journal. We used bibliometric software, including CiteSpace and R package bibliometrix, to visualize co-authorship relations, keyword citation burst analysis, co citation networks, keyword time zone map, burst references and cluster analysis. Results Our analysis included 993 publications. The bibliometric analysis revealed a steady increase in the number of publications on psoriasis and endothelial cells over the past decade. The United States was the leading contributor to this field. The Journal of Investigative Dermatology was the most high-yield publication journal. Burst references analysis identified key articles that have significantly influenced the field, including studies on the role of endothelial dysfunction in psoriasis pathogenesis and the association between psoriasis severity and cardiovascular outcomes. 9 clusters were grouped in the key-word citation network. "Expression", "inflammation", "endothelial growth factor" and "angiogenesis" were the research focuses, while "cardiovascular disease", "atherosclerosis", "endothelial dysfunction", and "oxidative stress" might be the future research hotspots. Conclusion This bibliometric analysis sheds light on the growing acknowledgement of the involvement of endothelial cells in psoriasis, with the United States taking the lead. It also emphasizes the necessity for additional research to unravel the underlying mechanisms connecting psoriasis, endothelial dysfunction, and cardiovascular comorbidities. Ultimately, this research will contribute to the development of enhanced management strategies for psoriasis patients.

Abstract
BACKGROUND Vascular dysfunction is a significant contributor to the pathophysiology of psoriasis. Some individuals have variation within the gene for vascular endothelial growth factor-A (VEGF-A), which confers an increased risk of developing psoriasis and having a severe disease phenotype, and may determine responsiveness to treatment. AIM To determine whether patients with psoriasis have alterations in cutaneous microvascular anatomy and physiology due to expression of VEGF and whether laser Doppler imaging has utility in the assessment of this. METHODS Twelve adult volunteers with Type 1 chronic plaque psoriasis underwent laser Doppler imaging of plaque and uninvolved skin. Skin biopsies were taken from the areas imaged for immunohistochemistry, including blood and lymphatic vessel markers, and VEGF-A isotype analysis (VEGF-A121, VEGF-A165 and VEGF-D). Venous blood was collected for DNA extraction, VEGF-A genotyping and peripheral blood mononuclear cell culture. RESULTS Mean blood vessel area (P < 0·01), number of blood vessels (P < 0·001), number of lymphatic vessels (P < 0·001) and blood flow (P < 0·001) was significantly increased in psoriasis plaques, as was expression of VEGF-A121 (P < 0·01), VEGF-A165 (P < 0·04) and VEGF-D (P < 0·01). Blood flow within psoriasis plaques was independent of their increased vascularity (P < 0·01) and may be associated with baseline productivity of VEGF. The number of blood vessels within uninvolved skin in patients with psoriasis was associated with the VEGF-A (rs833061) genotype (P = 0·01), in a relationship suggesting an allele dosing effect. CONCLUSION Noninvasive imaging of blood flow may help determine the cutaneous vascular signature for individual patients. This may be a useful prognostic indicator of psoriasis susceptibility and severity, and thus support selection of treatments.

Abstract
The physiology and pathology of the skin are influenced by daily oscillations driven by a master clock located in the brain, and peripheral clocks in individual cells. The pathogenesis of psoriasis is circadian-rhythmic, with flares of disease and symptoms such as itch typically being worse in the evening/night-time. Patients with psoriasis have changes in circadian oscillations of blood pressure and heart rate, supporting wider circadian disruption. In addition, shift work, a circadian misalignment challenge, is associated with psoriasis. These features may be due to underlying circadian control of key effector elements known to be relevant in psoriasis such as cell cycle, proliferation, apoptosis and inflammation. Indeed, peripheral clock pathology may lead to hyperproliferation of keratinocytes in the basal layers, insufficient apoptosis of differentiating keratinocytes in psoriatic epidermis, dysregulation of skin-resident and migratory immune cells and modulation of angiogenesis through circadian oscillation of vascular endothelial growth factor A (VEGF-A) in epidermal keratinocytes. Chronotherapeutic effects of topical steroids and topical vitamin D analogues have been reported, suggesting that knowledge of circadian phase may improve the efficacy, and therapeutic index of treatments for psoriasis. In this viewpoint essay, we review the current literature on circadian disruption in psoriasis. We explore the hypothesis that psoriasis is circadian-driven. We also suggest that investigation of the circadian components specific to psoriasis and that the in vitro investigation of circadian regulation of psoriasis will contribute to the development of a novel chronotherapeutic treatment strategy for personalised psoriasis management. We also propose that circadian oscillations of VEGF-A offer an opportunity to enhance the efficacy and tolerability of a novel anti-VEGF-A therapeutic approach, through the timed delivery of anti-VEGF-A drugs.

The Growth Factor Release from a Platelet-Rich Plasma Preparation Is Influenced by the Onset of Guttate Psoriasis: A Case Report. APPLIED SCIENCES-BASEL 2022.

Abstract
The involvement of platelets in immune and inflammatory processes is generally recognized; nevertheless, in psoriasis, their role is not clearly understood. We studied the in vitro growth factor release from a platelet-rich plasma preparation, the concentrated growth factors (CGF), in a case of a psoriasis subject three days before the onset of the papule. The CGF clots were incubated in a cell culture medium without growth supplements for 5 h and 1, 3, 6, 7, and 8 days, and the release kinetics of PDGF-AB, VEGF, TNF-α, and TGF-β1 were evaluated. The data, based on the results obtained during the case study, report a general increase in growth factor release in the psoriasis subject with respect to the healthy control, indicating an imbalance of growth factor production from blood cells. Although the results should be validated in the future, they show new aspects of this dermatological pathology, opening new possibilities both as the method of study, using CGF, and the involvement of platelets and growth factors in its development and maintenance.

Abstract
Chronic plaque psoriasis is an inflammatory skin disease in which genetic predisposition along with environmental factors lead to the development of the disease, which affects 2% of the UK’s population and is associated with extracutaneous morbidities and a reduced quality of life. A complex crosstalk between innate and adaptive immunity, the epithelia and the vasculature maintain the inflammatory milieu in psoriasis. Despite the development of promising treatment strategies, mostly targeting the immune system, treatments fail to fulfil every patient’s goals. Vascular endothelial growth factor‐A (VEGF‐A) mediates angiogenesis and is upregulated in the plaques and plasma of patients with psoriasis. Transgenic expression of VEGF‐A in experimental models led to the development of skin lesions that share many psoriasis features. Targeting VEGF‐A in in vivo models of psoriasis‐like inflammation resulted in disease clearance. Anti‐angiogenesis treatments are widely used for cancer and eye disease and there are clinical reports of patients treated with VEGF‐A inhibitors who have experienced Psoriasis Area and Severity Index improvement. Existing psoriasis treatments downregulate VEGF‐A and angiogenesis as part of their therapeutic effect. Pharmacogenetics studies suggest the existence of different genetic signatures within patients with psoriasis that correspond with different treatment responsiveness and disease severity. There is a subset of patients with psoriasis with an increased predisposition to produce high levels of VEGF‐A, who may be most likely to benefit from anti‐VEGF‐A therapy, offering an opportunity to personalize treatment in psoriasis. Anti‐VEGF‐A therapies may offer an alternative to existing anticytokine strategies or be complementary to standard treatments for the management of psoriasis.

Abstract
OBJECTIVES Vascular endothelial growth factor is an endothelial-specific growth factor that promotes endothelial cell proliferation, differentiation, and survival; mediates endothelium-dependent vasodilatation; induces microvascular hyperpermeability; and participates in interstitial matrix remodeling. The aim of the present study was to investigate the association between +405 G/C polymorphism of vascular endothelial growth factor and the risk of liver rejection in liver transplant recipients. MATERIALS AND METHODS The present study included 124 patients with liver disease that led to liver transplant. There were 22 patients who experienced histologically proven acute liver rejection, and the other 102 patients showed no rejection. Both groups were matched for sex and age. The VEGF+405 G/C polymorphism was evaluated by the polymerase chain reaction-restriction fragment-length polymorphism method. RESULTS Our analyses showed no significant relationships between genotypes and alleles of +405 G/C and risk of acute liver transplant rejection. CONCLUSIONS Our report indicated that there was no association between the carrier states of +405 G/C gene polymorphism of vascular endothelial growth factor and acute rejection or nonrejection of liver transplant.

Abstract
Vascular endothelial growth factor-A (VEGF-A), the main angiogenic mediator, plays a critical role in the pathogenesis of several inflammatory immune-mediated diseases, including psoriasis. Even though anti-angiogenic therapies, such as VEGF inhibitors, are licensed for the treatment of various cancers and eye disease, VEGF-targeting interventions are not part of current psoriasis therapy. In this viewpoint essay, we argue that the existing preclinical research evidence on the role of VEGF-A in the pathogenesis of psoriasis as well as clinical observations in patients who have experienced psoriasis remission during oncological anti-VEGF-A therapy strongly suggests to systematically explore angiogenesis targeting also in the management of psoriasis. We also point out that some psoriasis therapies decrease circulating levels of VEGF-A and normalise the psoriasis-associated vascular pathology in the papillary dermis of plaques of psoriasis and that a subset of patients with constitutionally high levels of VEGF-A may benefit most from the anti-angiogenic therapy we advocate here. Given that novel, well-targeted personalised medicine therapies for the development of psoriasis need to be developed, we explore the hypothesis that VEGF-A and signalling through its receptors constitute a promising target for therapeutic intervention in the future management of psoriasis.

Abstract
Background Expression of vascular endothelial growth factor A (VEGFA) is increased in chronic inflammatory skin diseases, including psoriasis, and loci for two VEGFA single nucleotide polymorphisms are associated with early‐onset psoriasis (presenting before the age of 40 years). Studies have suggested that expression of placenta growth factor (PGF) is also upregulated in cutaneous inflammation and that VEGFA‐mediated angiogenesis may be dependent on the simultaneous presence of PGF within the skin. Aim To elucidate the biological importance of PGF in psoriasis. Methods We investigated whether two commonly occurring PGF polymorphisms were associated with early‐onset psoriasis and the genetic interaction between VEGFA and PGF in psoriasis. Results We observed a significant (P = 0.04) association between rs2268614 TT and rs2268615 AA genotypes of PGF and early‐onset psoriasis. In addition, genetic complement, comprising the PGF rs2268615 AA genotype and the VEGFA −460 (rs833061) T allele, was significantly associated with the development of early‐onset psoriasis (P < 0.03). We identified that the VEGFA genotype influences PGF expression (P = 0.001) and that mean plasma levels of PGF are lower in patients with severe psoriasis compared with those with mild–moderate disease (P = 0.04). Conclusion Our observed genetic interaction between PGF and VEGFA appears relevant to psoriasis, a disease with an angiogenic basis, and may influence development of an antiangiogenic approach to treatment.

Abstract
The bioactive lipid sphingosine-1-phosphate (S1P), along with its receptors, modulates lymphocyte trafficking and immune responses to regulate skin inflammation. Macrophages are important in the pathogenesis of psoriasiform skin inflammation and express various S1P receptors. How they respond to S1P in skin inflammation remains unknown. We show that myeloid specific S1P receptor 1 (S1PR1) deletion enhances early inflammation in a mouse model of imiquimod-induced psoriasis, without altering the immune cell infiltrate. Mechanistically, myeloid S1PR1 deletion altered the formation of IL-1β, VEGF-A, and VEGF-C, and their receptors’ expression in psoriatic skin, which subsequently lead to reciprocal regulation of neoangiogenesis and neolymphangiogenesis. Experimental findings were corroborated in human clinical datasets and in knockout macrophages in vitro. Increased blood vessel but reduced lymph vessel density may explain the exacerbated inflammatory phenotype in conditional knockout mice. These findings assign a novel role to macrophage S1PR1 and provide a rationale for therapeutically targeting local S1P during skin inflammation.

Abstract
BACKGROUND Vascular endothelial growth factor is critically involved in ductus arteriosus closure. Polymorphisms in the vascular endothelial growth factor gene have been associated with several diseases in neonates and adults. AIM Herein, we investigated if vascular endothelial growth factor polymorphism rs2010963 status is associated with patent ductus arteriosus incidence and/or pharmacological treatment success. METHODS We assessed rs2010963 status in 814 preterm infants (<1500 g birth weight) by means of restriction fragment length polymorphism analysis. DNA samples were obtained from dry-spot cards used for the German national newborn screening program. Clinical data were obtained by retrospective chart review. RESULTS We could not find any statistically significant difference in the incidence of patent ductus arteriosus depending on vascular endothelial growth factor rs2010963 polymorphism status. Furthermore, no statistically significant associations between vascular endothelial growth factor polymorphism rs2010963 status and cyclooxygenase inhibitor treatment success were observed. CONCLUSION Our results indicate that there is no association between vascular endothelial growth factor polymorphism rs2010963 status and the occurrence of patent ductus arteriosus or the response to cyclooxygenase inhibitor treatment in a large cohort of preterm infants. Additional studies are needed to determine the role of genetic factors on patent ductus arteriosus incidence and treatment response.

Abstract
The treatment of advanced triple-negative breast cancer, which failed in first-line or second-line therapy, is a significant challenge. We conducted this retrospective study to explore the efficacy and safety of apatinib and capecitabine as the third-line treatment for advanced triple-negative breast cancer.This retrospective study involved 44 advanced triple-negative breast cancer patients who failed in first-line or second-line therapy in Tangshan People's Hospital from January 2016 to February 2017. Twenty-two patients received apatinib and capecitabine, while 22 patients were treated with capecitabine monotherapy as third-line therapy. The progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and adverse events were compared between 2 groups.The apatinib and capecitabine group exhibited a higher PFS than capecitabine group (P = .001). Meanwhile, ORR and DCR in apatinib and capecitabine group were better than in capecitabine group (P = .042; .016). The 2 groups showed no significant difference in adverse events except degree I-II bleeding (P = .021). Both the apatinib and capecitabine and the capecitabine regimens revealed good tolerability.The apatinib and capecitabine regimen can achieve a better efficacy and similar serious adverse events compared with capecitabine regimen as the third-line treatment for advanced triple-negative breast cancer.

Abstract
Aim: VEGF and EGF are assumed to be involved in the pathogenesis of psoriasis, while the impacts of their polymorphisms on psoriasis are inconsistent. Therefore, we hope to clarify these relationships in the Chinese Han population. Methods: A total of 131 patients with psoriasis vulgaris and 176 controls were enrolled. The polymorphisms rs833061 (T > C), rs10434 (G > A) in VEGFA, and rs4444903 (G > A), rs2237051 (A > G) in EGF of each participant were detected. The patients were treated with calcipotriol plus acitretin 30 mg/day for 8 weeks. Results: No SNPs of rs833061, rs10434, rs4444903 and rs2237051 were found to be associated with psoriasis susceptibility and efficacy. Although the mutation of rs10434A was associated with baseline disease severity (p = 0.026), and rs2237051G allele was associated with increased erythema during treatment (p = 0.015). Conclusion: The allele of rs2237051 G increased the erythema during the treatment, and no polymorphism of VEGF and EGF gene was found to be associated with the susceptibility and efficacy in psoriasis.

Abstract
The IL-1 family member cytokine IL-36γ is recognised as key mediator in the immunopathology of psoriasis, hallmarks of which involve the activation of both resident and infiltrating inflammatory myeloid cells and aberrant angiogenesis. This research demonstrates a role for IL-36γ in both myeloid activation and angiogenesis. We show that IL-36γ induces the production of psoriasis-associated cytokines from macrophages (IL-23 and TNFα) and that this response is enhanced in macrophages from psoriasis patients. This effect is specific for IL-36γ and could not be mimicked by other IL-1 family cytokines such as IL-1α. IL-36γ was also demonstrated to induce endothelial tube formation and branching, in a VEGF-A-dependent manner. Furthermore, IL-36γ-stimulated macrophages potently activated endothelial cells and led to increased adherence of monocytes, effects that were markedly more pronounced for psoriatic macrophages. Interestingly, regardless of stimulus, psoriasis monocytes showed increased adherence to both the stimulated and unstimulated endothelium when compared with monocytes from healthy individuals. Collectively, these findings show that IL-36γ has the potential to enhance endothelium directed leucocyte infiltration into the skin and strengthen the IL-23/IL-17 pathway adding to the growing evidence of pathogenetic roles for IL-36γ in psoriatic responses. Our findings also point to a cellular response, which could potentially explain cardiovascular comorbidities in psoriasis in the form of endothelial activation and increased monocyte adherence.

Abstract
Psoriasis, a common disease affecting 2%-3% of the UK population, produces significant impairment of quality of life and is an immense burden on sufferers and their families. Psoriasis is associated with significant cardiovascular comorbidity and the metabolic syndrome. Angiogenesis, a relatively under-researched component of psoriasis, is a key factor in pathogenesis of psoriasis and also contributes to the development of atherosclerosis. Vascular endothelial growth factor (VEGF) is a well-established mediator of pathological angiogenesis which is upregulated in psoriasis. It is possible that, in patients with psoriasis, cutaneous angiogenesis may be both a marker for systemic vascular pathology and a novel therapeutic target. In this viewpoint study, the role of VEGF-mediated angiogenesis as a cause for cardiovascular events in patients with psoriasis is explored.

Abstract
Psoriasis is a chronic inflammatory immune-mediated disorder associated and often coexisting with many other immune-related clinical conditions including those affecting the gastrointestinal tract. Data obtained from the reviewed literature suggest an association between psoriasis and pathologies of the oral cavity, both psoriasis-specific lesions, as well as non-specific, such as geographic tongue or fissured tongue. These findings show the importance of thorough examination of oral mucosa in psoriatic patients. Inflammatory bowel diseases (IBD) are also linked with psoriasis. Crohn’s disease and ulcerative colitis share a common genetic background, inflammatory pathways and have an evident iatrogenic anti-TNF treatment link, necessitating dermatological or gastroenterological care in patients with IBD or psoriasis, respectively, as well as treatment adjusted to manifestations. The presence of celiac disease-specific antibodies in psoriatic patients and their correlation with the severity of the disease show the association between these disorders. The linking pathogenesis comprises vitamin D deficiency, immune pathway, genetic background and increase in the intestinal permeability, which suggests a potential benefit from gluten-free diet among psoriatic patients. The link between psoriasis and non-alcoholic fatty liver disease implies screening patients for components of metabolic syndrome and lifestyle changes necessity. Some studies indicate increased prevalence of cancer in patients with psoriasis, probably due to negative influence of skin lesion impact on lifestyle rather than the role of psoriasis in carcinogenesis. However, there are no sufficient data to exclude such an oncogenic hit, which is yet to be confirmed. Therefore, all psoriasis-associated comorbidities establish the importance of a multidisciplinary approach in the treatment of these patients.

Abstract
BACKGROUND Recent studies suggest that vascular endothelial growth factor (VEGF) is involved in the development of major depressive disorder. The aim of this study is to investigate the interaction between vascular endothelial growth factor (VEGF) polymorphism (+405G/C, rs2010963) and negative life events in the pathogenesis of major depressive disorder (MDD). METHODS DNA genotyping was performed on peripheral blood leukocytes in 274 patients with MDD and 273 age-and sex-matched controls. The frequency and severity of negative life events were assessed by the Life Events Scale (LES). A logistics method was employed to assess the gene-environment interaction (G×E). RESULTS Differences in rs2010963 genotype distributions were observed between MDD patients and controls. Significant G×E interactions between allelic variation of rs2010963 and negative life events were observed. Individuals carrying the C alleles were susceptible to MDD only when exposed to high-negative life events. CONCLUSIONS These results indicate that interactions between the VEGF rs2010963 polymorphism and environment increases the risk of developing MDD.

Abstract
There is evidence that psoriatic arthritis is closely linked to angiogenesis. Morphological changes described in blood vessels of psoriatic arthritis joints suggest the presence of a dysregulated angiogenesis resulting in the formation of immature vessels. Even if the reason of this inefficient angiogenesis is still unclear, an imbalance between angiogenic and antiangiogenic factors is probably responsible for inducing a dysregulated angiogenesis in psoriatic arthritis, which seems to be involved in its pathogenesis and clinical features. Nevertheless, among chronic arthritides, while angiogenesis in rheumatoid arthritis has been largely studied with a great amount of literature data, limited data on angiogenesis role in psoriatic arthritis are available. This review article is focused on current knowledge on the mechanisms responsible for dysregulated angiogenesis in psoriatic arthritis.

Abstract
INTRODUCTION Psoriasis is a chronic inflammatory skin disease characterized by epidermal hyperproliferation, abnormal differentiation and inflammatory infiltration in the dermis. The dermal microvascular expansion associated with abnormal orientation and dilatation of capillaries in the biopsies of the psoriatic skin suggest that the disease is dependent on angiogenesis. AIM To analyze and compare the immunohistochemical expression of angiogenic factors - Vascular Endothelial Growth Factor (VEGF), von Willebrand Factor (vWF) and CD 34 in skin biopsies of psoriasis cases with control skin samples; and to correlate the expression of angiogenic factors with Psoriasis Area and Severity Clinical Index (PASI SCORE). MATERIALS AND METHODS This was a prospective case control study conducted over a period of 15 months. Thirty-two psoriasis cases and thirty control skin samples were included in the study. Skin biopsy specimen was taken from clinically diagnosed psoriasis cases who did not receive any treatment. The diagnosis of psoriasis vulgaris was confirmed after microscopic examination. Immunohistochemical expression for VEGF, vWF and CD 34 was studied. RESULTS VEGF expression in epidermis was significantly higher in cases when compared to control skin (p <0.01). CD 34 expression was significantly upregulated in cases when compared to controls (p<0.01). Von Willebrand factor expression was weak in both the cases and the controls. Significant correlation between the expression of VEGF and PASI score (r=0.944; p<0.01), and expression of CD 34 and PASI score was observed (r=0.942; p<0.01). CONCLUSION In the present study, significant overexpression of VEGF and CD 34 was noted in cases when compared to controls. The keratinocytes in the psoriatic skin lesions were recognized as a source of pro-angiogenic cytokines namely the VEGF and other growth factors which promotes angiogenesis in psoriatic plaque. Angiogenesis plays an important role in genesis and development of psoriasis vulgaris. Therefore, development of targeted anti-angiogenic therapy might be beneficial for this chronic disabling dermatological disease.

Abstract
Angiogenesis is the growth of new blood vessels from pre-existing vessels. It is a biological process essential in physiological wound healing or pathological inflammation and tumor growth, which underlies a complex interplay of stimulating and inhibiting signals. Extracellular matrix, cells of innate and adaptive immunity and endothelial cells itself are a major source of angiogenic factors that activate or inhibit specific receptors and consequently influence intracellular signaling pathways. Most inflammatory and neoplastic diseases in dermatology are characterized by excessive angiogenesis, such as psoriasis, atopic dermatitis, as well as melanoma, non-melanoma skin cancer, but also benign vascular neoplasia. In this article we describe current knowledge of angiogenesis and its most relevant mechanisms in different dermatological disorders with particular emphasis on the angiogenic factors (vascular endothelial growth factor) and angiopoietins as a target of current and future directions of anti-angiogenic therapy.

Abstract
Background and objective: Given the postulated the role of inflammation and possible contribution of
lymphangiogenesis in oral lichen planus, this study aimed to assess any associated presence of VEGFR-3. Material
and Methods: This cross-sectional study was performed on 52 formalin fixed and paraffin embedded blocks of oral
lichen planus (pathological diagnosis based on Modified WHO criteria), comprising 25 of erosive and 27 of reticular
type, along with 60 samples of normal mucosa (with minimal inflammation from clinical and histopathological aspects)
obtained at crown lengthening surgery. Four micron sections were cut from paraffin blocks and stained with H and
E for confirmation of diagnosis and by immunohistochemistry with primary antibodies against VEGFR-3. Negative
controls were provided by omission of primary antibody and placenta was considered as a positive control. Data were
analyzed by Chi-square, Mann-Whitney and Kruskal-wallis tests and P <0.05 was considered statistically significant.
Findings: VEGFR-3 expression was apparent in 61.5% of lichen planus specimens and 5% of those from normal
mucosa (p<0.001). Also, the average number of stained vessels was significantly higher in oral lichen planus than in
normal mucosa (p<0.001). VEGFR-3 expression in oral lichen planus (p=0.262) and the average number of stained
vessels (p=0.092) demonstrated no significant difference according to the type. Conclusion: It appears that VEGFR-3
expression might be involved in the pathogenesis of the oral lichen planus through increasing lymphatic vessels and
lymphangiogenesis.

[PMID: 28110689 DOI: 10.1016/j.mehy.2016.12.003] [Citation(s) in RCA: 43] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2016] [Revised: 10/13/2016] [Accepted: 12/08/2016] [Indexed: 01/21/2023]
Abstract
Psoriasis is a chronic skin disease also affecting other sites such as joints. This disease highly depends on inflammation and angiogenesis as well as other pathways. At each step of the psoriasis molecular pathway, different inflammatory cytokines and angiogenic growth factors are involved such as hypoxia inducible factor-1 α (HIF-1 α), vascular endothelial growth factor (VEGF), matrix metalo proteinases (MMPs), basic fibroblast growth factor (bFGF), Angiopoitin-2, interleukin-8 (IL-8), IL-17, and IL-2. Beside the mentioned growth factors and cytokines, cellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) which play roles in both angiogenesis and inflammation are also involved in the pathogenesis. Cannabinoids are active compounds of Cannabina Sativa inducing their effects through cannabinoid receptors (CBs). JWH-133 is a synthetic cannabinoid with strong anti-angiogenic and anti-inflammatory activities. This agent is able to inhibit HIF-1 α, VEGF, MMPs, bFGF, IL-8, IL-17, and other mentioned cytokines and adhesion molecules both in vivo and in vitro. Altogether, authors suggest using this cannabinoid for treatment of psoriasis due to its potential in suppressing the two main steps of psoriatic pathogenesis. Of course complementary animal studies and human trials are still required.

Abstract
INTRODUCTION Affecting 1 million people in the UK, psoriasis is a commonly diagnosed inflammatory disease arising from autoimmune processes that are triggered by environmental factors in genetically susceptible individuals. The pathophysiology of psoriasis has been widely studied and there is evidence that angiogenesis is a key component. AREAS COVERED In this review the role of vascular endothelial growth factor-A (VEGF), as a key angiogenic mediator in psoriasis pathogenesis is discussed. VEGF is found in higher levels in plaques, normal skin and plasma of patients with psoriasis. The level of VEGF also fluctuates in accordance with disease activity and in response to conventional treatments. There are several VEGF inhibitors currently licenced for use; primarily in the fields of oncology and there are case reports of patients being treated with these therapies for metastatic cancer who have demonstrated significant improvement in their psoriasis. VEGF inhibitory agents have suggested promising utility for the treatment of psoriasis following animal studies. EXPERT OPINION VEGF may represent a novel treatment target in psoriasis. However, VEGF inhibitors can cause significant side effects such as hypertension and left ventricular dysfunction. The risks of treatment must be carefully evaluated before VEGF inhibitors are trialled or advocated for psoriasis.

[PMID: 26848216 PMCID: PMC4737833 DOI: 10.5021/ad.2016.28.1.30] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2014] [Revised: 04/22/2015] [Accepted: 05/11/2015] [Indexed: 12/17/2022] Open
Abstract
Background Evidence regarding the vascular endothelial growth factor A (VEGFA) as a potent mediator of angiogenesis and inflammation in psoriasis has revealed variations in this gene as surrogate markers of psoriasis. Objective VEGFA gene polymorphisms (-1540 C/A, -1512 Ins18, -460 T/C, and +405 C/G) in psoriasis susceptibility in Turkish population were investigated. Methods A total of 200 age, sex and ethnicity-matched psoriatic and healthy individuals were examined for clinical type, response to therapy, serum VEGFA and its receptor levels, genotypes and haplotypes. Results The +405 GG, +405 CG, -1540 CA, and -1512 +Ins18 genotypes conferred a significant risk for developing psoriasis. The C-InsTC haplotype in the controls and C+InsTG, A+InsTC, and A-InsTG haplotypes in psoriatic patients were observed to be significantly high. Increased serum levels of VEGFA were detected in psoriatic patients with the C-InsTC haplotype than that in the controls. The +405 GG genotype was significantly more frequent in psoriatic patients with a positive family history, and the moderate form of psoriasis was more frequent among C+InsTG haplotype carriers than that among the other patients. The +405 GG genotype was found to be more frequent in patients responding to oral retinoids. Serum VEGFR1/FLT1 and VEGFR2/KDR levels were not significantly different when psoriatic patients and controls were stratified based on the risk polymorphic variants. Conclusion VEGFA gene +405 GG and CG, -1512+Ins18, and -1540 CA genotypes are associated with an increased risk of psoriasis in Turkish population. The G allele at +405 and an 18-bp insertion at -1512 are primarily the risk factors for psoriasis, and this risk is potentiated by the presence of the A allele at the -1540 locus.

Indigo naturalis and its component tryptanthrin exert anti-angiogenic effect by arresting cell cycle and inhibiting Akt and FAK signaling in human vascular endothelial cells. JOURNAL OF ETHNOPHARMACOLOGY 2015; 174:474-81. [PMID: 26341616 DOI: 10.1016/j.jep.2015.08.050] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/14/2015] [Revised: 08/24/2015] [Accepted: 08/27/2015] [Indexed: 05/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Indigo naturalis has been used to treat inflammatory diseases and dermatosis, including psoriasis, since thousands of years in China. It has been proven effective in our previous clinical studies on treating psoriasis, but the active component and the mechanism of how indigo naturalis working still needs to be clarified. Since the dysregulated angiogenesis is known to play an important role in the pathogenesis of psoriasis, the anti-angiogenic effect of indigo naturalis and tryptanthrin, a pure component of indigo naturalis, was investigated. MATERIALS AND METHODS The in vivo angiogenesis was studied by chick chorioallantoic membrane assay. The in vitro studies were performed using human vascular endothelial cells. Cell viability was determined by MTT assay. Cell cycle distribution was revealed by flow cytometry. The cellular messenger (m)RNA or protein expression level was analyzed by real-time RT-PCR or Western blot, respectively. Transwell filter migration assay and matrix gel-induced tube formation method were applied to examine the angiogenic potential. RESULTS Indigo naturalis significantly inhibited the in vivo vascular endothelial growth factor (VEGF)-induced angiogenesis, as well as tryptanthrin. In vitro studies confirmed that indigo naturalis and tryptanthrin reduced the number of viable vascular endothelial cells. Tryptanthrin resulted in a cell cycle arrest and dose-dependently decreased the expressions of cyclin A, cyclin B, cyclin dependent kinase(CDK) 1 and 2, but not cyclin D and cyclin E, at both the mRNA and protein levels. The migration and tube formation of vascular endothelial cells were significantly inhibited by tryptanthrin in a dose-dependent manner. Result also showed that tryptanthrin could reduce the phosphorylated levels of both protein kinase B (PKB or Akt) and focal adhesion kinase (FAK). CONCLUSIONS All together, these results demonstrated the anti-angiogenic effect of tryptanthrin, the acting component of indigo naturalis and revealed the underlying mechanism by inhibiting the cell cycle progression, cell migration and tube formation, likely mediated through blocking the Akt and FAK pathways.

Abstract
Psoriasis is an immune-mediated, genetic disease manifesting in the skin or joints or both. A diverse team of clinicians with a range of expertise is often needed to treat the disease. Psoriasis provides many challenges including high prevalence, chronicity, disfiguration, disability, and associated comorbidity. Understanding the role of immune function in psoriasis and the interplay between the innate and adaptive immune system has helped to manage this complex disease, which affects patients far beyond the skin. In this Seminar, we highlight the clinical diversity of psoriasis and associated comorbid diseases. We describe recent developments in psoriasis epidemiology, pathogenesis, and genetics to better understand present trends in psoriasis management. Our key objective is to raise awareness of the complexity of this multifaceted disease, the potential of state-of-the-art therapeutic approaches, and the need for early diagnosis and comprehensive management of patients with psoriasis.

Abstract
Vascular endothelial growth factor (VEGF) is a key growth factor, regulating the neovascularization, during embryogenesis, skeletal growth, reproductive functions and pathological processes. The VEGF receptors (VEGFR) are present in endothelial cells and other cell types, such as vascular smooth muscle cells, hematopoietic stem cells, monocytes, neurons, macrophages, and platelets. Angiogenesis is initiated by the activation of vascular endothelial cells through several factors. The excess dermal vascularity and VEGF production are markers of psoriasis. The pathological role of VEGF/VEGFR signaling during the psoriasis onset and evolution makes it a promising target for the treatment of psoriasis. Antibodies and other types of molecules targeting the VEGF pathway are currently evaluated in arresting the evolution of psoriasis.

Abstract
Background Vascular endothelial growth factor (VEGF) is an important angiogenic factor and may be connected with chronic immune-mediated inflammatory diseases (IMIDs) to some extent. However, previous researches about the relationship between the +405G>C (dbSNP: rs2010963) polymorphism in VEGF gene and the risk of IMIDs are controversial and inconsistent. So we conducted this meta-analysis to assess whether the relationship between the +405G>C polymorphism in the 5'-UTR region of VEGF gene and IMID susceptibility exists. Methods Our literature search was conducted on the PubMed, Embase, Web of science, Chinese National Knowledge Infrastructure, and Chinese Biomedical databases to retrieve for eligible studies. Odds ratios as well as their 95 % confidence intervals were utilized to deduce the possible relationship. Results A total number of 5175 patients with IMIDs and 7069 healthy controls from 27 case-control studies were included. For the overall eligible data collected in our meta-analysis, there was no marked relationship between +405G>C polymorphism and the risk of IMIDs. However, subgroup analysis by ethnicity suggested that +405C allele could be a protective factor for IMIDs in Asians, whereas an opposite conclusion was drawn in Caucasians. Conclusion Thus, we may come to the conclusion that the VEGF +405G>C polymorphism could be associated with IMIDs, and the correlation might vary with ethnic groups.

Abstract
Angiogenesis, the growth of new blood vessels from pre-existing vessels, occurs physiologically in wound healing, during inflammatory diseases, and in tumor growth. Lymphangiogenesis can be activated in inflammation and tumor metastasis. The family of vascular endothelial growth factors (VEGFs) and angiopoietins are essential for angiogenesis and lymphangiogenesis. The angiogenic process is tightly regulated by VEGFs, angiopoietins, and endogenous inhibitors. VEGFs and angiopoietins exert their effects by activating specific receptors present on blood and lymphatic endothelial cells. There is now compelling evidence that cells of innate and adaptive immunity (macrophages, mast cells, neutrophils, eosinophils, lymphocytes) are a major source of angiogenic and lymphangiogenic factors. Chronic inflammatory skin diseases such as psoriasis and atopic dermatitis are characterized by altered angiogenesis, lymphangiogenesis, or both. Also such acute inflammatory skin disorders as urticaria, ultraviolet B-induced damage, and angioedema are associated with changes in angiogenic factors. In systemic sclerosis there is a switch from proangiogenic to antiangiogenic factors that play a role in the defective vascular process of this disorder. As yet, there are no clinical trials showing that canonical VEGF/VEGF receptor-targeted strategies can modulate inflammatory skin diseases. Novel strategies targeting other angiogenic/lymphangiogenic pathways should also be investigated.

Abstract
The role of VEGF -634G/C polymorphism has been involved in the investigations of susceptibility to autoimmune diseases, but the conclusion remains controversial. Here, we have performed a meta-analysis to clarify the relationship between them. All relevant articles updating to August 2013 were searched in PubMed and EMBASE. Crude odds ratios (ORs) with 95% confidence intervals (CIs) based on the available articles were calculated. A total of 24 independent studies associated with autoimmune disease were analyzed in our research. The results show that VEGF -634G/C polymorphism was associated with susceptibility to autoimmune disease in Asian population (C vs. G: OR=0.88, 95% CI: 0.80-0.96, P=0.543; CC vs. GG: OR=0.77, 95% CI: 0.63-0.93, P=0.787; CC+GC vs. GG: OR=0.80, 95% CI: 0.67-0.96, P=0.080 by random effects model). Nevertheless, no significant associations were found in total population or in other stratified groups. In the current meta-analysis, we reveal a significant association between VEGF -634G/C polymorphism and susceptibility to autoimmune diseases in Asian population.

Abstract
Geographic tongue (GT) and fissured tongue (FT) are the more frequent oral lesions in patients with psoriasis. The aims of this study were to compare the prevalence of GT/FT between psoriasis group (PG) and healthy controls (HC) and investigate the correlation between GT/FT and psoriasis severity using the PASI and age of psoriasis onset. Three hundred and forty-eight PG and 348 HC were selected. According to the age of psoriasis onset, the individuals were classified as having early psoriasis and late psoriasis. The severity of vulgaris psoriasis was determined according to PASI. A follow-up was conducted in patients with psoriasis vulgaris (PV) with GT to evaluate the progression of oral and cutaneous lesions. The FT and GT were more frequent in PG than in HC. The incidence of GT was higher in patients with early psoriasis and that of FT in late-psoriasis. There is association between psoriasis intensity and GT; and a higher monthly decrease of PASI score in patients without GT. The presence of GT and FT is higher in PG than in the HC. GT is associated with disease severity and may be a marker of the psoriasis severity.

Abstract
Bevacizumab, a monoclonal antibody against vascular endothelial growth factor (VEGF), is employed for treatment of several cancers and retinopathies. Although previous reports of remission of psoriasis with bevacizumab do exist, but its current experience for psoriatic arthritis (PsA) is still limited. In this report, we describe a patient with metastatic renal cell cancer, psoriasis and PsA, who experienced a complete remission of psoriasis and PsA during bevacizumab therapy without any other management for psoriasis and PsA. We also found a flare up of his psoriatic disease after switching to other kinase inhibitors like sorafenib or sunitinib. This suggests that bevacizumab might have a promising future in the treatment of psoriasis and PsA.

Abstract
The contribution of genetic polymorphisms in the vascular endothelial growth factor (VEGF) gene to psoriasis risk is a controversial topic. The aim of this meta-analysis was to investigate large-scale evidence to determine the degree to which four common VEGF polymorphisms (+405C>G [dbSNP: rs2010963], -460T>C [dbSNP: rs833061], -2578C>A [dbSNP: rs699947], and -1154G>A [dbSNP: rs1570360]) are associated with susceptibility to psoriasis. A literature search of PubMed, Embase, Web of Science, Chinese National Knowledge Infrastructure, and Chinese Biomedical Literature Database was conducted to identify all eligible studies published before September 15, 2013. The principal outcome measure for evaluating the strength of the association was crude odds ratios (ORs) along with their corresponding 95% confidence intervals (95% CIs). Two thousand five hundred thirty-one patients and 2670 controls from nine case-control studies detailing a possible association between the VEGF genotypes and psoriasis risk were selected. Our meta-analysis provides evidence that two independent alleles +405G and -460C may be a protective factor for psoriasis in Asians, whereas the -1154A allele had a slight but statistically significant preventive effect on the development of psoriasis in Caucasians. The -2578C>A polymorphism, however, did not correlate with any significant difference between patients and healthy controls, even when the groups were stratified by ethnicity. Results from the meta-analysis do support the hypothesis that single-nucleotide polymorphism markers at +405C>G, -460C>T, and -1154G>A of the VEGF gene may serve as biological markers of psoriasis. Future studies should investigate interactions among multiple genotypes and environmental exposures to identify the role of proangiogenic markers in psoriasis and to delineate the underlying mechanisms of psoriasis.

Abstract
Psoriasis is a chronic inflammatory skin disease. The cause of psoriasis is unknown, although genetics may play a key role in its development. Treatment of the disease varies with severity. Topical drugs, such as corticosteroids, coal tar, retinoids and vitamin D analogs, are commonly used to treat mild psoriasis. Phototherapy and systemic drugs, such as calcineurin inhibitors, methotrexate, acitretin and biological drugs, are usually used to treat moderate-to-severe psoriasis. Not all patients respond well to treatment, and some can develop severe adverse effects. Interindividual differences in several genes may explain this variation in response to treatment. Pharmacogenetics and pharmacogenomics can facilitate more personalized medicine and prevent the adverse effects associated with treatment.

[PMID: 24659464 DOI: 10.1002/jcla.21717] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2013] [Accepted: 10/28/2013] [Indexed: 01/23/2023] Open
Abstract
BACKGROUND Vascular endothelial growth factor (VEGF), transforming growth factor β1 (TGF-β1), and nitric oxide (NO) have been reported to be contributory factors to the pathogenesis of psoriasis vulgaris. In the current study, we aimed to investigate the association between the levels of VEGF, TGF-β1, and NO and psoriasis severity (as expressed by psoriasis area severity index, PASI). METHODS Fifty-eight patients with psoriasis vulgaris and twenty-two controls were included in the study. The serum levels of VEGF and TGF-β1 were estimated by ELISA technique. The serum levels of NO were determined by colorimetric method. RESULTS The serum levels of VEGF, TGF-β1, and NO were significantly higher in patients than controls. Moreover, the serum levels of the studied biochemical variables in patients with severe disease activity were significantly higher than mild cases. The duration of disease showed significant positive correlations with each VEGF (r = 0.35, P < 0.01) and TGF-β1 (r = 0.41, P < 0.05). In addition, the PASI score was significantly positively correlated with VEGF (r = 0.65, P < 0.001), TGF-β1 (r = 0.31, P < 0.05), and NO (r = 0.51, P < 0.001). CONCLUSION These findings suggest an association between psoriasis disease severity and serum levels of VEGF, TGF-β1, and NO, which can be recognized as markers of the psoriasis severity. The modulation of their production may represent a therapeutic potential strategy for psoriasis.

Abstract
Angiogenesis is a host-mediated mechanism in disease pathophysiology. The vascular endothelial growth factor (VEGF) pathway is a major determinant of angiogenesis, and a comprehensive annotation of the functional variation in this pathway is essential to understand the genetic basis of angiogenesis-related diseases. We assessed the allelic heterogeneity of gene expression, population specificity of cis expression quantitative trait loci (eQTLs), and eQTL function in luciferase assays in CEU and Yoruba people of Ibadan, Nigeria (YRI) HapMap lymphoblastoid cell lines in 23 resequenced genes. Among 356 cis-eQTLs, 155 and 174 were unique to CEU and YRI, respectively, and 27 were shared between CEU and YRI. Two cis-eQTLs provided mechanistic evidence for two genome-wide association study findings. Five eQTLs were tested for function in luciferase assays and the effect of two KRAS variants was concordant with the eQTL effect. Two eQTLs found in each of PRKCE, PIK3C2A, and MAP2K6 could predict 44%, 37%, and 45% of the variance in gene expression, respectively. This is the first analysis focusing on the pattern of functional genetic variation of the VEGF pathway genes in CEU and YRI populations and providing mechanistic evidence for genetic association studies of diseases for which angiogenesis plays a pathophysiologic role.

Abstract
Psoriasis is a common inflammatory autoimmune condition in which environmental factors and genetic predisposition contribute to the development of disease in susceptible individuals. Angiogenesis is known to be a key pathogenic feature of psoriasis. Local and systemic elevation of vascular endothelial growth factor (VEGF)-A has been demonstrated in the skin and plasma of patients with psoriasis and is known to correlate with improvement following some traditional psoriasis treatments. A number of VEGF inhibitors are licensed for the treatment of malignancies and eye disease and isolated case reports suggest that some individuals with psoriasis may improve when exposed to these agents. The small number of cases and lack of unified reporting measures makes it difficult to draw generalizations and underline the heterogeneity of psoriasis as a disease entity. Though not yet licensed for the treatment of psoriasis in humans, experimental data supports the potential of VEGF inhibitors to influence relevant aspects of human cell biology (such as endothelial cell differentiation) and to improve animal models of skin disease. Given the multi-factorial nature of psoriasis it is unlikely that VEGF inhibitors will be effective in all patients, however they have the potential to be a valuable addition to the therapeutic arsenal in selected cases. Current VEGF inhibitors in clinical use are associated with a number of potentially serious side effects including hypertension, left ventricular dysfunction, and gastrointestinal perforation. Such risks require careful consideration in psoriasis populations particularly in light of growing concerns linking psoriasis to increased cardiovascular risk.

Abstract
BACKGROUND To study the possible association between vascular endothelial growth factor gene polymorphism and diabetic macular oedema, and its correlation to the outcomes of anti-vascular endothelial growth factor treatment. DESIGN Prospective study. PARTICIPANTS 392 diabetic patients were included; 180 patients of them had no retinopathy, 212 patients had diabetic retinopathy. Diabetic retinopathy patients were classified into four groups as defined by the absence or presence of macular oedema or proliferative retinopathy. METHODS In all subjects, polymerase chain reaction-restriction fragment length polymorphism was conducted to detect the vascular endothelial growth factor gene C-634G polymorphism. Serum levels of vascular endothelial growth factor were estimated. Changes of visual acuity and central macular thickness after bevacizumab treatment in diabetic macular oedema patients of different genotypes were monitored for 9-12 months. MAIN OUTCOME MEASURES Vascular endothelial growth factor C-634G genotypes distribution in different groups; correlation between genotypes, and changes in visual acuity and central macular thickness after intravitreal bevacizumab treatment. RESULTS CC genotype was significantly prevalent among diabetic macular oedema patients (P = 0.019). Significant higher serum levels of vascular endothelial growth factor were detected in diabetic retinopathy and diabetic macular oedema patients with CC genotype (P = 0.02, 0.016). After bevacizumab treatment, individuals with genotypes CG and GG have a decreased chance of positive treatment outcomes compared t with CC genotype (P < 0.001). CONCLUSIONS Vascular endothelial growth factor C-634G polymorphism (CC genotype) is a genetic risk factor for diabetic macular oedema, and its presence provides significantly better visual outcome following bevacizumab treatment.

Abstract
Psoriasis is a chronic proliferative skin disease and is usually treated with topical glucocorticoids, which act through the glucocorticoid receptor (GR), a component of the physiological systems essential for immune responses, differentiation, and homeostasis. To investigate the possible role of GR in the pathogenesis of psoriasis, normal and psoriatic lesional skin were recruited. Firstly, the immunolocalization of GR in the skin and cultured epidermal keratinocytes were determined by immunofluorescence. In normal skin and cultured human epidermal keratinocytes, intracellular GR is localized in the nuclei, while in psoriatic skin and cultured keratinocytes, GR is in the cytoplasm. Next, we investigated possible factors associated with the cytoplasmic distribution. We found that VEGF and IFN-γ led to impaired nuclear translocation of GR through p53 and microtubule-inhibitor, vincristine, and inhibited nuclear uptake of GR in normal keratinocytes. In addition to dexamethasone, interleukin (IL)-13 was also able to transfer GR into nuclei of psoriatic keratinocytes. Furthermore, discontinuation of dexamethasone induced cytoplasmic retention of GR in normal keratinocytes. In contrast, energy depletion of normal epidermal keratinocytes did not change the nuclear distribution of GR. To confirm our findings in vivo, an imiquimod-induced psoriasis-like skin mouse model was included. IL-13 ameliorated (but vincristine exacerbated) the skin lesions on the mouse. Taken together, our findings define that impaired nuclear translocation of GR is associated with VEGF, IFN-γ, p53, and microtubule. Therapeutic strategies designed to accumulate GR in the nucleus, such as IL-13, may be beneficial for the therapy of psoriasis.

Abstract
BACKGROUND Graves' disease (GD) is a consequence of genetic and environmental factors. Vascular endothelial growth factor (VEGF) is a strong angiogenic and mitogenic factor, which plays a key role in lymphocyte infiltration, and hypervascularization in the thyroid gland of patients with GD. AIM The aim of this study is to investigate the relationship between GD and A-2578C, T-460C and G+405C single nucleotide polymorphisms (SNPs) of VEGF gene, as well as to evaluate whether there are any relationships between genotypes and some clinical/laboratory parameters of GD. METHODS We analyzed the genotype and allele distributions of the above mentioned SNPs in 167 patients with established GD diagnosis and 203 healthy controls by real-time PCR combined with melting curve analysis using fluorescence-labeled hybridization probes. RESULTS The distribution of VEGF A-2578C and T-460C genotypes and allele frequencies in control and GD groups were not significantly different. With regard to the +405 polymorphism, the frequency of C allele was 1.8-fold increased in GD patients compared to controls, and the CC genotype was associated with a 4.6-fold increased disease risk. There was no relationship between some clinical/laboratory parameters with G+405C polymorphism. However, in -2578C allele carrying GD patients the anti-thyroid antibody levels were increased according to wild homozygous. Additionally, -2578C and -460T alleles were related with early (at age before 40) disease onset. CONCLUSION VEGF +405 polymorphism may be a risk factor for GD, while the -2578 SNP is related with increased autoantibody production.

Abstract
Angiogenesis is an important host process that interacts with cancer cells to promote growth, invasion, and metastasis. Numerous therapeutic agents targeting the VEGF pathway have been developed. Host variability in VEGF pathway can influence angiogenesis-dependent signaling, altering sensitivity to antiangiogenic drugs and prognosis. A systematic review and meta-analysis was conducted (May 1990-July 2011). Eligible studies involved cancer patients and compared polymorphisms in the VEGF pathway [VEGF and molecules directly interacting with VEGF: KDR, FLT1, FGF, FGF2, FGFR, NRP1, endostatin (encoded by COL18A1)], and reported one of the following outcomes: overall survival, progression-free survival, time to recurrence, disease-free survival, response rate, or drug toxicity. We identified 48 cancer studies assessing prognosis and 12 cancer studies exploring pharmacogenetics of anti-VEGF therapy across various VEGF pathway polymorphisms. There was marked inter- and intradisease site heterogeneity in the effect of polymorphisms on both outcome and response to therapy. Meta-analyses of 5 VEGF polymorphisms (+936C>T, -460T>C, +405G>C, -1154G>A, and -2578C>A) identified a significant prognostic relationship: VEGF +405G>C variants showed a highly statistically significant improvement in overall survival [HR, 0.74; 95% confidence interval, 0.60-0.91; P = 0.004]. Variants (heterozygotes and/or homozygotes) of VEGF +405G>C were significantly associated with improved survival in a meta-analysis of multiple cancer sites.

Abstract
Vascular endothelial growth factor (VEGF) has long been recognized as a hypotensive mediator. Little is known regarding the contribution of polymorphisms in VEGF gene to essential hypertension (EH), however. We aimed to investigate the association between +405 VEGF C/G single nucleotide polymorphism (SNP) and occurrence of EH in a sample of patients with diabetes. A study population of 474 subjects with diabetes of which 45.6% (216) had EH was enrolled in this study. Interviews and physical examinations were performed in a clinical setting. Subjects were matched in baseline anthropometric and biochemical characteristics except for total cholesterol. Genotyping of +405 VEGF C/G (rs2010963) SNP was carried out using polymerase chain reaction-restriction fragment length polymorphism. The allelic distribution of the sample did not violate Hardy-Weinberg equilibrium. Subjects with EH had a higher frequency of G allele (P = 0.005). Additionally, those with EH had a significantly higher frequency of GG genotype (P = 0.015). In multivariate logistic regression models controlling for possible confounders, having GG against CC genotype was associated with an odds ratio of 2.51 (95% CI: 1.44-4.38; P = 0.001). Moreover, presence of each G allele was linked to a 1.58-fold increase in risk of having EH (95% CI: 1.200-2.086; P = 0.001). In conclusion, +405 VEGF C/G SNP is associated with EH in patients with diabetes, suggesting presence of G allele and GG or CG genotype confer susceptibility towards EH.
