Transcription factor oncogenes such as GLI and c-MYC are central to the pathogenesis of human tumors. GLI encodes a zinc finger protein that is activated by Sonic Hedgehog signaling. Mutations in this pathway induce GLI expression in basal cell carcinoma, and expression of GLI in mice is sufficient to induce these skin tumors. We used microarrays to(More)
Constitutive activation of MEK-ERK signaling is often found in melanomas. Here, we identify a mechanism that links ERK with JNK signaling in human melanoma. Constitutively active ERK increases c-Jun transcription and stability, which are mediated by CREB and GSK3, respectively. Subsequently, c-Jun increases transcription of target genes, including RACK1, an(More)
Immunosenescence is the age-related decline and dysfunction of protective immunity leading to a marked increase in the risk of infections, autoimmune disease, and cancer. The majority of studies have focused on immunosenescence in the systemic immune system; information concerning the effect of aging on intestinal immunity is limited. Isolated lymphoid(More)
KLF4 is induced upon growth-arrest in vitro and during epithelial maturation in vivo, and is essential for proper cell fate specification of post-mitotic cells. In spite of a normal role in post-mitotic cells, expression is upregulated and constitutive in certain tumor types. KLF4 functions as an oncogene in vitro, and enforced expression in basal cells of(More)
The alpha(4) integrins alpha(4)beta(7) and alpha(4)beta(1), and their ligands mucosal vascular addressin cell adhesion molecule 1 (MAdCAM-1) and VCAM-1, have diverse functions, including roles in the formation of secondary lymphoid tissues at early time points during the colonization and clustering of the fetal lymphoid tissue inducer (LTi) cells and at(More)
BACKGROUND A significant portion of cutaneous melanoma may remain after subtotal incisional biopsy. The accuracy of microstaging and impact on clinical practice in this scenario are unknown. OBJECTIVE Our purpose was to examine microstaging accuracy of an initial incisional biopsy with a significant portion of the clinical lesion remaining (> or =50%). (More)
Intraoperative, real-time fluorescence imaging may significantly improve tumor visualization and resection and postoperatively, in pathological assessment. To this end, we sought to determine the optimal FDA approved therapeutic monoclonal antibody for optical imaging of human cutaneous squamous cell carcinoma (cSCC). A near-infrared (NIR) fluorescent probe(More)
Pigmented Paget's disease is a rare variant that is often confused clinically and histologically with melanoma in situ. Herein, we describe a case of pigmented extramammary Paget's disease involving the axilla of a 79-year-old white male thought initially to represent malignant melanoma clinically and histologically. Review of the literature reveals that(More)
In excising basal and squamous cell carcinomata, the surgical margin that is wide enough to completely remove the tumor an acceptable percentage of the time and narrow enough to minimize removal of excessive normal tissue must be selected. This task can be reliably accomplished with comprehensive knowledge of factors that affect subclinical tumor extension(More)
