Bio:  I am a Professional Research Assistant in the Box Lab, under the supervision of Drs. Neil Box and Tamara Terzian since May of 2012. My research interests are in Melanoma and the tanning response governed by the p53 gene and other relevant biochemical pathways. I am also interested in the connection between the biological mechanisms of the tanning response and how they relate to public health with regard to preventing skin diseases in adolescents, who may be prone to later life susceptibility. 

I am passionate about connecting local musicians and artists with Colorado non-profits in order to help aim charitable interests of local music scenes, which led to my co-founding and chair position with Helping Hands, a local non-profit organization that strives to meet that exact objective.  Two of my favorite hobbies include playing guitar and audio engineering/producing in my DIY home recording studio​.

Wanida Stevens, BA

Senior Professional Research Assistant

Education: 2004 - Bachelor of Arts in Molecular, Cellular and Developmental Biology, University of Colorado at Boulder
Bachelor of Arts in English, Ramkhamheang University, Bangkok, Thailand

Experience:  2014-present: Senior Professional Research Assistant Department Dermatology with Dr. Neil Box. My work focuses on the regulation of the tumor suppressor p53 in tumorigenesis using mouse models. I am responsible for routine maintenance of the lab such as ordering, compliance to regulations and training students on various techniques. I also conduct mouse work including husbandry, necropsies, tumor collection, genetic experiments and drug treatments.

2013-2014: Senior Professional Research Assistant Department of Physiology and Biophysics with Dr. Abigail Person. I provided histological and surgical support. Specifically, I developed successful protocols for a series of difficult antibodies to determine the neurotransmitter content of neurons of interest. In addition, I transfected neurons in vivo by performing survival surgeries on mice under a stereotaxic device. I characterized the location of Cre expression in a transgenic mouse, helping the lab to determine whether a particular line is suitable for their studies.

2005-2013: Professional Research Assistant Department of Physiology and Biophysics with Dr. Celia Sladek. My research was focused on: 1) characterizing the intracellular trafficking of the Neurokinin 3 receptor (NK3-R), a G-protein-coupled receptor using antibodies that I purified. I also used a variety of methodologies that encompass molecular biology, biochemistry, immunohistochemistry, confocal microscopy and image analysis as well as cell culture techniques; and 2) evaluation of the regulation of vasopressin and oxytocin release from the posterior pituitary. The latter studies included in vitro perifusion followed by radioimmunoassay of the hormones. I also conducted stereotaxic hypothalamic injections of pharmacological agents followed by histological assessment of their effect on cfos activation post- hemorrhage.

Hobbies:  I love hiking, walking my husky Jake and reading. I also perform Thai traditional dances as a member of the Colorado Thai Heritage Preservation Association.

The mouse as a model for human melanocyte and melanoma development

Melanocytes are the pigment producing cells within the skin. Melanocytes give rise to melanoma, a particularly invasive and deadly tumor type. In order to better understand genes that are important in melanoma risk and progression, we are interested in the important pathways that regulate development of melanoblasts, or melanocyte stem cells. Historically, many of the pathways that regulate melanocyte development, pigment production and propensity to transform to melanoma were discovered with investigation of mouse pigmentation mutations. We have assembled a number of mouse pigmentation mutations, identified through random insertional mutagenesis screens or mouse chemical mutagenesis screens that are involved in regulating melanocyte numbers within the skin. Investigation of the molecular basis of these mouse pigmentation phenotypes identifies new candidates genes and pathways that may control normal human pigmentation phenotypes. In order to test for the role of these genes in human pigmentation we have isolated DNA from a large collection of Colorado children who are part of a longitudinal study of melanocytic nevus development. Some of these children have been followed since 3 years of age with annual skin exams that have kept track of pigmentation phenotypes such as skin, hair and eye color, and numbers and size of incident and pre-existing melanocytic nevi. The majority of children are now 9 years of age. We are examining genetic polymorphisms in a number of important mouse melanocyte development pathways that may play a role in determining normal human pigmentation phenotypes and in melanoma risk. Our interests also include characterisation of the major gene expression differences between human melanoblasts isolated from foreskin, and differentiated melanocytes. We are comparing these gene expression profiles with those from malignant melanoma in order to investigate putative "melanoma stem cell" markers that may have therapeutic significance.
