Acute lung injury (ALI) and its more severe form, acute respiratory distress syndrome (ARDS) are the leading causes of death in critical care. Despite extensive efforts in research and clinical medicine, mortality remains high in these diseases. Perfluorocarbon (PFC), a chemical compound known as liquid ventilation medium, is capable of dissolving large(More)
Wound healing is a complex process that is characterized by an initial inflammatory phase followed by a proliferative phase. This transition is a critical regulatory point; however, the factors that mediate this process are not fully understood. Here, we evaluated microRNAs (miRs) in skin wound healing and characterized the dynamic change of the miRNome in(More)
Cutaneous squamous cell carcinoma (cSCC) is a malignancy of epidermal keratinocytes that is responsible for approximately 20% of skin cancer-related death yearly. We have previously compared the microRNA (miRNA) expression profile of cSCC to healthy skin and found the dysregulation of miRNAs in human cSCC. In this study we show that miR-31 is overexpressed(More)
Wound healing is a basic biological process restoring the integrity of the skin. The role of microRNAs during this process remains largely unexplored. By using an in vivo human skin wound healing model, we show here that the expression of miR-31 is gradually upregulated in wound edge keratinocytes in the inflammatory (1 day after injury) through the(More)
The ability to rapidly restore the integrity of a broken skin barrier is critical and is the ultimate goal of therapies for hard-to-heal-ulcers. Unfortunately effective treatments to enhance healing and reduce scarring are still lacking. A deeper understanding of the physiology of normal repair and of the pathology of delayed healing is a prerequisite for(More)
Psoriasis is an immune-mediated inflammatory disease, which is associated with a high risk of developing systemic comorbidities, such as obesity, cardiovascular disease, and diabetes mellitus. However, the mechanistic links between psoriatic skin inflammation and systemic comorbidities remain largely unknown. MicroRNAs (miRNAs) are recently discovered gene(More)
Smoke inhalation injury (SII) is associated with significant morbidity and mortality in burn patients, and effective treatments are lacking. Perfluorocarbons (PFCs) have a protective effect against acute lung injury. We aimed to assess the therapeutic effects of perfluorohexane on burn patients with SII. Patients with burns complicated by moderately severe(More)
An imbalance of the adaptive immune system mediated by various T cells plays a pivotal role in the pathogenesis of atopic dermatitis (AD). Traditionally, sustained exposure of pathogens tailors immune responses and drives the development of specialized T helper (Th) 2-bias cytokine environment. The increasing understanding of T cell biology has refreshed(More)
Cutaneous squamous cell carcinoma (cSCC) is the second most common cancer and a leading cause of cancer mortality among solid organ transplant recipients. MicroRNAs (miR) are short RNAs that regulate gene expression and cellular functions. Here, we show a negative correlation between miR-203 expression and the differentiation grade of cSCC. Functionally,(More)
