Ning Xu Landén
I am an associate professor in experimental dermatology and venereology and PI working in Unit of Dermatology, Department of Medicine, Karolinska Institutet. I received my Ph.D. degree in medical virology from Uppsala University, Sweden (2008) and did postdoc research at Molecular Dermatology research group led by Prof. Mona Ståhle in Karolinska Institutet (2009-2013). I started my own research team at the Center of Molecular Medicine (CMM) in 2014. More information about my research group can be found at http://www.xulandenlab.com
Bowel chronic non-healing wounds and psoriasis are major and rising health and economic burdens worldwide and lack of effective treatment. Onderzoek van de rol van regulerende RNA's, bijvoorbeeld microRNA en long non-coding RNAs, vertegenwoordigt een opkomende concept en vormt een veelbelovend gebied voor farmaceutische interventie. The goal of our laboratory is to unravel the role (s) of regulatory RNAs in skin wound healing and in psoriasis. Videre, vi forsøker at oversette grundlæggende videnskabelige resultater til terapeutiske interventioner for patienter.
Project 1. The role of non-coding RNAs in human skin wound healing
The aim of our research is to develop novel RNA-based treatments to improve healing of human skin wounds. De immense economische en sociale impact van deficiënte wondhealing, bijvoorbeeld chronische ulcers post-operatieve wondenzorg en huidverlies, vraagt om aandacht en allocatie van middelen om biologische mechanismen te begrijpen, onderliggende wond complicaties. Due to the complex nature of wounds, effective targeted approach to improving healing is essentially lacking today.
De onlangse discovery of non-coding RNAs (ncRNAs) as powerful gene regulators provides hope to develop novel RNA-based treatments for a wide variety of diseases. Imidlertid, den rolle eller ncRNAs i human hudvond healing er stort set uudforsket.
The objective of our study is to reveal the role (s) of ncRNAs in skin wound healing and to explore the potential of RNA-based therapy for chronic wounds. We focus primarily on small ncRNAs, ie microRNAs (miRNAs) and long-non-coding RNAs (lncRNAs) and study:
(i) The expression profiles of miRNA / lncRNA in injured human skin;
(ii) The biological function of differentially expressed miRNAs / lncRNAs in wounds;
(iii) The molecular mechanisms mediating the biological functions of wound related miRNAs / lncRNAs;
(iv) The therapeutic potentials of targeting wound related miRNAs.
Our research network is composed of both clinicians and scientists, which allows us to perform ‘Bench-to-Bedside’ research. At present, we are investigating the novel roles of miRNAs and lncRNAs in skin wounds using our unique collection of human wound tissues. In the next step, we aim to translate our basic scientific findings into therapeutic interventions for wound patients.

Project 2. Investigation of the mechanistic links between psoriasis and co-morbidities
Psoriasis is an immune-mediated inflammatory disease of the skin. It is a lifelong disease with spontaneous remissions and exacerbations, affecting the patients’ life quality substantially, and there is no cure for it today. Epidemiological studies show that psoriasis patients have increased risks of developing systemic co-morbidities, e.g. obesity, overt diabetes and cardiovascular disease; however, the molecular mechanisms behind these co-morbidities remain unexplored. We have previously demonstrated that miRNAs play important roles in skin inflammation of psoriasis. Here, we study whether miRNA could also be a key mechanistic link between psoriasis and its co-morbidities, using materials from a large biobank of psoriasis patients in Stockholm. This study will further increase our understanding about pathogenesis of psoriasis. It is essential for the effective management of psoriasis and prevention of its related co-morbidities.
