Differentially expressed miRNAs for sebaceous gland carcinoma of the eyelid and TP53 mutation
Ontology highlight
ABSTRACT: To screen the related miRNAs in the occurence and development of sebaceous gland carcinoma(SGC) of the eyelid , we have employed Human Agilient microarray expression profiling as a discovery platform to identify differentially expressed miRNAs for SGC and TP53 mtation related miRNAs. Human formalin-fixed paraffin-embedded (FFPE) SGC tissues and para-carcinoma sebaceous gland(SG) FFPE samples from SGC patients were screened using microarray assay. Human FFPE SGC tissues containing TP53 mutation and human FFPE SGC tissues without TP53 mutation were screened using microarray. The overlap of two sets of microarray differentially upregulated miRNAs were selected as our research object.
Project description:Sebaceous gland carcinoma is the frequent malignant tumor of the eyelid. However, there is limited understanding of how altered gene expression of sebaceous gland carcinoma of the eyelid related to the pathogenesis. In this study, to identify genes involved in sebaceous gland carcinoma of the eyelid, global-scale gene expression analysis was carried out using a GeneChip® system.
Project description:Samples were taken from patients undergoing cancer excision for pagetoid (wide) sebaceous gland carcinoma (SGC) and different individuals undergoing excision for nodular (local) SGC. Diifferent individuals who did not have cancer as Control samples, specifically their tarsal plate, were also taken.

Project description:To identify the molecular background of eyelid sebaceous gland carcinomas (SCs), the integrated whole-exome sequencing and transcriptome sequencing for five eyelid SCs were conducted in this study.
Project description:Meibomian glands (MGs) are specialized holocrine sebaceous glands embedded in the tarsal plate of the eyelids. The cell heterogeneity of MGs is not well characterized. In this study, we performed a spatial transcriptomic analysis of murine eyelid using the 10X Visium platform.
Project description:Using RNA-sequencing we tested how human sebaceous glands cells respond to bacterial stimuli by comparing the mRNA profiles of sebaceous gland cells treated with lipopolysaccharide to vehicle treated sebaceous gland cells.
Project description:Cisplatin is the first-line agent utilized for the clinical treatment of a wide variety of solid tumors including gastric cancer. However, the intrinsic or acquired cisplatin resistance is often occurred in patients with gastric cancer and resulted in failure of cisplatin therapy. In order to investigate if miRNA involves in cisplatin resistance of human gastric cancer, we first screened and compared the expression of miRNAs between cisplatin resistant gastric cancer cell lines SGC-7901/DDP and BGC-823/DDP and their sensitive parental cells by miRNAs microarray.
Project description:Pla2g2f is dominantly expressed in the suprabasal layer of mouse epidermis. Microarray gene profiling supported the overall tendency of epidermal and sebaceous gland hyperplasia as well as alopecia in Pla2g2f-transgenic skin.
