miRNA expression profiling in squamous cell carcinoma (SCC)

Project description:Despite its prevalence, the molecular basis of squamous cell carcinoma (SCC) remains poorly understood. We recently identified the developmental transcription factor Grhl3 as a potent tumor suppressor of SCC, and demonstrated that targeting of Grhl3 by a miR-21-dependent proto-oncogenic network underpins SCC in humans. Reduced levels of GRHL3 and its target gene PTEN are evident in human skin, and head and neck SCC, associated with increased expression of miR-21, which targets both tumor suppressors. Our data defines the miR-21-GRHL3-PTEN-axis as a critical tumor suppressor pathway in SCC. Total RNA was isolated from two SCC primary tissue samples and their matched normal skin controls.

ArrayCGH mapping of chromosome 3 aberrations in lung Squamous Cell Carcinoma (SCC)

Project description:To prospectively identify new oncogenes implicated in lung Squamous Cell Carcinoma pathogenesis, we investigated chromosome 3 aberrations in advanced tumours using arrayCGH. These aberrations are indeed among the most frequent aberrations in lung SCC and correlate with SCC patient's poor prognosis. We precisely map regions of recurrent losses at 3p and gains at 3q25-qter in a series of lung SCC. We moreover uncover 3q26.3-q27 high level amplifications in 20% of tumours. Keywords: ArrayCGH, Lung Squamous Cell Carcinoma, 3q26.3, SOX2 Profiling of 26 advanced (stage III) lung SCC. Replicates : each tumor sample is hybridized together with a normal dna sample to one microarray. Each microarray contain 3 replicates per BAC clone.

Photodynamic oncolytic virus therapy for central nervous system malignancies

Project description:The goal of the study was to determine whether photodynamic oncolytic virus therapy of glioblastoma and malignant meningioma xenografts in mice alters transciptomics associated with efficacy. RNA sequencing was used from tumors treated with PBS, laser, G47delta-KillerRed, and G47delta-KillerRed and laser, which is photodynamic oncolytic virus therapy.

The Role of JNK1/2 in Mouse Lung Squamous Cell Carcinoma (SCC) Development

Project description:Lung cancer is the leading cause of cancer death in USA. Squamous Cell Carcinoma (SCC) is one of the subtypes of lung cancer. It is still largely unknown which genes or pathways regulate lung SCC development. Recently, we found JNK1/2 pathway was inhibited in mouse lung SCC induced by double ablation of Pten and Lkb1 in mouse lung epithelial cells. Now we aim to identify a genome-wide molecular signature of JNK1/2 signaling in mouse squamous cell carcinoma cells and determine pathways that transduce JNK1/2 signaling.

Defining an invasion signature at the leading edge of cutaneous squamous cell carcinoma (SCC): IL-24 driven MMP-7 and MMP-13 expression.

Project description:Purpose: Primary cutaneous squamous cell carcinoma (SCC) can be an invasive cancer in skin and has the potential to metastasize. We aimed to define the cancer related molecular changes that distinguish non-invasive from invasive SCC. Experimental design: We used laser capture microdissection technique in combination with cDNA microarray analysis in order to determine molecular changes that associate with SCC progression. Results: We defined invasion-associated genes as those udifferentially regulated only in SCC invasive nests, but not in actinic keratosis-like dysplasia or SCC in situ regions, compared to normal epidermis. We designated these genes as “invasion signature gene set of cutaneous SCC”. Overall we found 383 up- and 354 down-regulated probe-sets that constitute the invasion signature gene set. As part of this profile, SCC invasion is associated with aberrant gene expression changes of numerous MMPs including MMP7 (FCH=5.43, FDR<0.01) and MMP13 (FCH=12.53, FDR<0.01). IL-24 is also up-regulated in the leading invasive edge of SCC (FCH=6.74, FDR<0.01). IL-24 enhanced mRNA expression of both MMP7 and MMP13 in a human SCC cell line. Laminin332, which is one of the target molecules of MMP7, had altered expression at the leading edge of SCC invasion nests at both the genomic and protein level. Conclusions: We defined the distribution of MMPs within human cutaneous SCC tissue showing distinct expression with progression from normal skin to actinic keratosis to SCC in situ to invasive carcinoma. We further suggest a potential role for IL-24 in progression to invasion via MMP7 and MMP13. Laser capture microdissection was performed on 5 cases of actinic keratosis, 5 cases of in situ SCC, and 5 cases of invasive SCC.
