Endothelial To Mesenchymal Transition (Endomt) In The Pathogenesis Of Systemic Sclerosis-Associated Pulmonary Fibrosis And Pulmonary Arterial Hypertension. Myth Or Reality?, Sergio A. Jimenez, Sonsoles Piera-Velazquez

Department of Dermatology and Cutaneous Biology Faculty Papers

Systemic Sclerosis (SSc) is a systemic autoimmune disease characterized by progressive fibrosis of skin and multiple internal organs and severe functional and structural microvascular alterations. SSc is considered to be the prototypic systemic fibrotic disorder. Despite currently available therapeutic approaches SSc has a high mortality rate owing to the development of SSc-associated interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH), complications that have emerged as the most frequent causes of disability and mortality in SSc. The pathogenesis of the fibrotic process in SSc is complex and despite extensive investigation the exact mechanisms have remained elusive. Myofibroblasts are the cells …

Ectopic Mineralization Of Cartilage And Collagen-Rich Tendons And Ligaments In Enpp1asj-2j Mice., Jieyu Zhang, Nathaniel A Dyment, David W Rowe, Sarah Y Siu, John P Sundberg, Jouni Uitto, Qiaoli Li

Department of Dermatology and Cutaneous Biology Faculty Papers

Generalized arterial calcification of infancy (GACI), an autosomal recessive disorder caused by mutations in the ENPP1 gene, manifests with extensive mineralization of the cardiovascular system. A spontaneous asj-2J mutant mouse has been characterized as a model for GACI. Previous studies focused on phenotypic characterization of skin and vascular tissues. This study further examined the ectopic mineralization phenotype of cartilage, collagen-rich tendons and ligaments in this mouse model. The mice were placed on either control diet or the "acceleration diet" for up to 12 weeks of age. Soft connective tissues, such as ear (elastic cartilage) and trachea (hyaline cartilage), were processed …

Pressure To Publish For Residency Applicants In Dermatology, Jordan V. Wang, Matthew S. Keller

Department of Dermatology and Cutaneous Biology Faculty Papers

As it grows increasingly difficult to match into a dermatology residency program each year, there is a widening gap in research accomplishments between those who have and have not matched successfully. Applicants should be aware of the current trends in order to maximize their chances of matching. Such research inequality may subsequently lead to increases in the pressure to publish and the incidence of academic misrepresentation. Academic dermatology programs should be aware of these issues in order to help their students successfully match and exercise caution when reviewing the curricula vitae of applicants. We believe that student mentors in dermatology …

C-Src/Cav1-Dependent Activation Of The Egfr By Dsg2., Andrew M. Overmiller, Kathleen P. Mcguinn, Brett J. Roberts, Felicia Cooper, Donna M. Brennan-Crispi, Takahiro Deguchi, Sirkku Peltonen, James K. Wahl, Mỹ G. Mahoney

Department of Dermatology and Cutaneous Biology Faculty Papers

The desmosomal cadherin, desmoglein 2 (Dsg2), is deregulated in a variety of human cancers including those of the skin. When ectopically expressed in the epidermis of transgenic mice, Dsg2 activates multiple mitogenic signaling pathways and increases susceptibility to tumorigenesis. However, the molecular mechanism responsible for Dsg2-mediated cellular signaling is poorly understood. Here we show overexpression as well as co-localization of Dsg2 and EGFR in cutaneous SCCs in vivo. Using HaCaT keratinocytes, knockdown of Dsg2 decreases EGFR expression and abrogates the activation of EGFR, c-Src and Stat3, but not Erk1/2 or Akt, in response to EGF ligand stimulation. To determine whether …

ETSU Faculty Works

Background: Indoor tanning elevates the risk for melanoma, which is now the most common cancer in US women aged 25-29. Public policies restricting access to indoor tanning by minors to reduce melanoma morbidity and mortality in teens are emerging. In the United States, the most common policy restricting indoor tanning in minors involves parents providing either written or in person consent for the minor to purchase a tanning visit. The effectiveness of this policy relies on parents being properly educated about the harms of indoor tanning to their children.

Objective: This randomized controlled trial will test the efficacy …

Biosimilars: Potential Implications For Clinicians, Misty G. Eleryan, Sophia Akhiyat, Monica Rengifo-Pardo, Alison Ehrlich

Dermatology Faculty Publications

With the expiration of patent protection for several biologics looming, the production of highly similar therapeutic agents has begun to emerge on the pharmaceutical market. These alternative drugs are referred to as biosimilars. Many anticipate that the introduction of these agents will result in a reduction in health care costs, which may create a more affordable biopharmaceutical market and also improve patient access. In contrast to generics, which are exact copies of their original products, biosimilars are not identical to their reference products. Due to concern about the safety and efficacy of biosimilars, separate regulatory approval pathways have been developed …

A Comparison Of Various Monoclonal Antibodies To The Previous Standard Of Care Chemotherapy In The Treatment Of Advanced-Stage Melanoma, Kevin Verde, Lauren Johnson, Alex Clancy, Ashley Goldberg, Aleia Monden, Priya Philip

Internet Journal of Allied Health Sciences and Practice

In the year 2015, it is estimated that the number of new cases of invasive melanoma will be 42,670 in males and 31,200 in females.¹ Melanoma is treatable with early diagnosis; however, more advanced disease has devastating outcomes. For the past decade, two chemotherapy agents, dacarbazine and temozolomide, have been the treatment of choice for advanced stage III or IV melanoma requiring systemic treatment. Interleukin-2 (IL-2) therapy has been used but with serious side effects. More recently, the focus has shifted to monoclonal antibodies and enzyme inhibitors as the main systemic treatment for advanced cutaneous melanoma. This literature review …

Regulation Of Uv-Protective Pathways Downstream Of The Melanocortin 1 Receptor In Melanocytes, Erin M. Wolf Horrell

Theses and Dissertations--Physiology

Malignant cutaneous melanoma is the deadliest form of skin cancer, and a majority of melanoma diagnoses are a result of exposure to ultraviolet (UV) radiation. UV radiation causes DNA damage, which if not repaired correctly via nucleotide excision repair (NER) can result in mutations and melanomagenesis. The melanocortin 1 receptor (MC1R) is a G_s protein coupled receptor located on melanocyte plasma membranes and is involved in protecting the skin from UV induced damage. MC1R signaling results in the activation of two protective pathways: 1) induction of eumelanin synthesis downstream of micropthalmia-associated transcription factor (MITF) and 2) acceleration of NER …

Increased Expression Of Napdh Oxidase 4 In Systemic Sclerosis Dermal Fibroblasts: Regulation By Transforming Growth Factor Β., Sonsoles Piera-Velazquez, Alma Makul, Sergio A. Jimenez

Department of Dermatology and Cutaneous Biology Faculty Papers

OBJECTIVE: Systemic sclerosis (SSc) is characterized by severe and often progressive fibrosis of the skin and multiple internal organs. The mechanisms responsible for these alterations remain obscure, although excessive reactive oxygen species (ROS)-mediated oxidative stress has been implicated. NOX-4 is 1 of 7 isoforms of NADPH oxidase responsible for the generation of ROS. The purpose of this study was to examine NOX-4 expression in skin and cultured dermal fibroblasts from SSc patients and to examine its regulation by transforming growth factor β1 (TGFβ1).

METHODS: NOX-4 was assessed in normal and SSc skin by immunohistologic analysis and in normal and SSc …

Lysyl Hydroxylase 3 Localizes To Epidermal Basement Membrane And Is Reduced In Patients With Recessive Dystrophic Epidermolysis Bullosa., Stephen A Watt, Jasbani H S Dayal, Sheila Wright, Megan Riddle, Celine Pourreyron, James R Mcmillan, Roy M Kimble, Marco Prisco, Ulrike Gartner, Emma Warbrick, W H Irwin Mclean, Irene M Leigh, John A Mcgrath, Julio C Salas-Alanis, Jakub Tolar, Andrew P South

Department of Dermatology and Cutaneous Biology Faculty Papers

Recessive dystrophic epidermolysis bullosa (RDEB) is caused by mutations in COL7A1 resulting in reduced or absent type VII collagen, aberrant anchoring fibril formation and subsequent dermal-epidermal fragility. Here, we identify a significant decrease in PLOD3 expression and its encoded protein, the collagen modifying enzyme lysyl hydroxylase 3 (LH3), in RDEB. We show abundant LH3 localising to the basement membrane in normal skin which is severely depleted in RDEB patient skin. We demonstrate expression is in-part regulated by endogenous type VII collagen and that, in agreement with previous studies, even small reductions in LH3 expression lead to significantly less secreted LH3 …

Rac1 P29s Regulates Pd-L1 Expression In Melanoma., Ha Linh Vu, Sheera Rosenbaum, Timothy J. Purwin, Michael A. Davies, Andrew E. Aplin

Department of Cancer Biology Faculty Papers

Whole exome sequencing of cutaneous melanoma has led to the detection of P29 mutations in RAC1 in 5-9% of samples, but the role of RAC1 P29 mutations in melanoma biology remains unclear. Using reverse phase protein array analysis to examine the changes in protein/phospho-protein expression, we identified cyclin B1, PD-L1, Ets-1, and Syk as being selectively upregulated with RAC1 P29S expression and downregulated with RAC1 P29S depletion. Using the melanoma patient samples in TCGA, we found PD-L1 expression to be significantly increased in RAC1 P29S patients compared to RAC1 WT as well as other RAC1 mutants. The finding that PD-L1 …

Burns are often seen in clinics or hospitals. Majority of burns are minor burns, which can be managed in outpatient setting with satisfactory result. The healing outcome depends on physician’s knowledge and competencies in burn pathogenesis and basic principles of burn care. Initial treatment of burns consists of emergency evaluation, assessment of depth and severity of burns and considerations for referral. The principles of minor wound therapy include cooling, cleansing, pain management, and topical therapy. Recently, many topical agents are available and indicated for first to second degree burn. Silver sulfadiazine (SSD) is the standard treatment; however, it has some …

Nf-Κb Regulation Of C-Flip Promotes Tnfα-Mediated Raf Inhibitor Resistance In Melanoma., Yongping Shao, Kaitlyn Le, Hanyin Cheng, Andrew E. Aplin

Department of Cancer Biology Faculty Papers

Targeted inhibitors elicit heterogeneous clinical responses in genetically stratified groups of patients. Although most studies focus on tumor intrinsic properties, factors in the tumor microenvironment were recently found to modulate the response to inhibitors. Here, we show that in cutaneous BRAF V600E melanoma, the cytokine tumor necrosis factor-α (TNFα) blocks RAF inhibitor-induced apoptosis via activation of NF-κB. Several NF-κB-dependent factors are upregulated following TNFα and RAF inhibitor treatment. Of these factors, we show that death receptor inhibitor cellular caspase 8 (FLICE)-like inhibitory protein (c-FLIP) is required for TNFα-induced protection against RAF inhibitor. Overexpression of c-FLIP_S or c-FLIP_L isoform decreased RAF …
