Project description:Using RNA-sequencing analysis of peripheral blood cells from 11 cervical cancer patients, 21 cervical intraepithelial neoplasia patients and 19 healthy controls, we identified a group of differentially expressed genes. A real time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was applied to the validation of candidate markers in the blood of 115 patients and 46 healthy controls. The results suggest that a six-gene predictor set (GZMB, NDUFA1, GPR84, NUAK1, AGAP1 and CIR1) can be used as candidate genes for the detection of cervical cancer.
Project description:Transcriptional profiling of Homo sapiens inflammatory skin diseases (whole skin biospies): Psoriasis (Pso), vs Atopic Dermatitis (AD) vs Lichen planus (Li), vs Contact Eczema (KE), vs Healthy control (KO) In recent years, different genes and proteins have been highlighted as potential biomarkers for psoriasis, one of the most common inflammatory skin diseases worldwide. However, most of these markers are not psoriasis-specific but also found in other inflammatory disorders. We performed an unsupervised cluster analysis of gene expression profiles in 150 psoriasis patients and other inflammatory skin diseases (atopic dermatitis, lichen planus, contact eczema, and healthy controls). We identified a cluster of IL-17/TNFα-associated genes specifically expressed in psoriasis, among which IL-36γ was the most outstanding marker. In subsequent immunohistological analyses IL-36γ was confirmed to be expressed in psoriasis lesions only. IL-36γ peripheral blood serum levels were found to be closely associated with disease activity, and they decreased after anti-TNFα-treatment. Furthermore, IL-36γ immunohistochemistry was found to be a helpful marker in the histological differential diagnosis between psoriasis and eczema in diagnostically challenging cases. These features highlight IL-36γ as a valuable biomarker in psoriasis patients, both for diagnostic purposes and measurement of disease activity during the clinical course. Furthermore, IL-36γ might also provide a future drug target, due to its potential amplifier role in TNFα- and IL-17 pathways in psoriatic skin inflammation.

Project description:We prospectively investigated gene expression profiles of cervical cancer patients undergoing concurrent chemoradiation. Upregulated genes in the circumstance of anemia were analyzed. Peripheral blood of 20 patients (bulky stage IB –IVA cervical squamous cell carcinomas) undergoing concurrent chemoradiation at four time-points was collected. Total RNA extracted by PaxGene Blood RNA System was analyzed with microarrays and MetaCoreTM functional network analyses. Fifty-three genes were significantly differentially expressed during concurrent chemoradiation. Fetal and embryonic hemoglobin genes were upregulated when patients had been severely myelosuppressed. Twenty-eight genes significantly correlated with the hemoglobin genes are involved in responses to hypoxia and oxygenation, TGF-β signaling, cell cycle suppression, G-protein signaling, and transcriptional regulation. C-Myc has the highest rank in transcriptional co-regulation. Besides, IGKV1D-13 was significantly downregulated in patients with severe hematologic toxicity. These approaches identified biological processes in peripheral blood modulated by concurrent chemoradiation and subsequent anemia. Keywords: chemoradiation, microarray, network analysis
Project description:Purpose: We aimed to elucidate the potential mechanisms of effective responsiveness to PD-1 monoclonal antibody and evaluate more reliable biomarkers for improving the predictive utility of the dominant populations of recurrent cervical cancer (RCC) to receive immunotherapy. Methods: Peripheral blood samples of PD-L1 positive patients with RCC treated with second-line PD-1 monoclonal antibody were collected prior to treatment initiation and after the treatment. Differentially expressed genes (DEGs) were analyzed between partial response (PR) patient and progressive disease (PD) patients.
