Gene expression patterns in Normal Human Epidermal Melanocytes at different time points

Project description:Normal human epidermal melanocytes (NHEM, purchased from PromoCell) were culture for one (7 days) or two weeks (14 days) and subsequently, total RNA was isolated and cDNA array analysis was performed. The array was used to determine general gene expression patterns in primary melanocytes. Moreover, gene expression alterations during cell culturing (one or two weeks) can be detected. Finally, the gene expression array is used to compared gene expression paterns with melanoma cell and tissue gene expression patterns or with other primary cell lines.

MiRNA-sequencing in normal human epidermal melanocytes, melanoblast-related cells and melanoma cell lines

Project description:The study aims to identify differences in miRNA expression during melanoma development. Therefore, normal human epidermal melanocytes (NHEM) were de-differentiated into melanoblast-related cells (MBrCs) to model processes during embryonic differentiation and to compare them to the tumorigenic phenotype in melanoma development.

Glycomic gene comparison between human epidermal melanocytes and human metastatic melanoma cells

Project description:To discover potential biomarkers of melanoma development and progression, we embarked on studies comparing the glycomic gene profiles of normal human epidermal melanocytes with human metastatic melanoma (MM) cells represented by A375 and G361 cell lines. Glycomic features embody all of those enzymatic, membranous and regulatory proteins that influence glycan ‘sugar’ formation/degradation on a cell. Comparative expression profiling of glycomic genes indicated that several genes were differentially expressed between normal melanocytes and MM cells. We speculate that glycome genes differentially expressed in MM cells help drive malignant and metastatic behavior of MM cells and could potentially serve as a biomarker(s) of melanoma progression.

Gene expression profile of human melanocytes derived from iPS cells

Project description:This experiment was designed to show the similarity among normal human epidermal melanocytes, melanocytes derived from human 3F-induced pluripotent stem (iPS) cells, and human 3F-iPS cells. Human 3F-iPS cells without c-myc were established and then differentiated into melanocytes. The differentiated cells were collected and the gene expression profile was compared to normal human epidermal melanocytes (NHEMs) and orginal 3F-iPS cells.

RNA sequencing of particulate metter treated melanocytes

Project description:Purpose: Determine the mechanism of particulate matter-induced signaling in melanocytes. Method: Primary human epidermal melanocytes were treated with particulate matter (5 μg/cm2) and incubated for 24 h. Total RNA (1 ug) from melanocytes were extracted and subjected to library synthesis. Results: Particulate matter-treated melanocytes exhibited upregulation of ER stress, unfolded protein response, and melanogenesis-related molecules. Conclusion: Particulate matter-induced melanocyte signaling was well evaluated using RNA sequencing.

RNA sequencing of hydrogen peroxide (H2O2)-treated melanocytes

Project description:Purpose: Determine the mechanism of H2O2-induced signaling in melanocytes. Method: Primary human epidermal melanocytes were treated with H2O2 (200 μM) and incubated for 24 h. Total RNA (500 ng) from melanocytes were extracted and subjected to library synthesis. Results: H2O2-treated melanocytes exhibited upregulation of cell death and type 1 interferon-related genes. Conclusion: H2O2-induced melanocyte signaling was well evaluated using RNA sequencing.

Smart-seq analysis comparing melanocytes from Spry1flox/flox mice tail epidermis to the melanocytes derived from Spry1 epidermis specific knockout mice tail and back epidermis

Project description:The function and survival of melanocytes is regulated by an elaborate network of paracrine factors synthesized mainly by epidermal keratinocytes. Keratinocytes and melanocytes respond to UV exposure by eliciting a tanning response. However, how keratinocytes and melanocytes interact in the absence of UV exposure is unknown. Here, we demonstrate that after Spry1 knockout in epidermal keratinocytes, melanocyte stem cells (McSCs) in the hair follicle exit the stem cell niche without depleting the pool of these cells. We also found that McSCs migrate to the epidermis in a Scf/C-kit-dependent manner induced by a tanning-like response resulting from Spry1 loss in epidermal keratinocytes. Once there, these cells differentiate into functional melanocytes. These findings show the potential for developing therapies for skin pigmentation disorders by manipulating McSCs.

RNA sequencing of high mobility group box 1-treated melanocytes [hmgb1]

Project description:Purpose: Determine the mechanism of high mobility group box 1 (HMGB1)-induced signaling in melanocytes. Method: Primary human epidermal melanocytes were treated with HMGB1 (1 μg/ml) and incubated for 24 h. Total RNA (500 ng) from melanocytes were extracted and subjected to library synthesis. Results: HMGB1-treated melanocytes exhibited upregulation of cell death and type 1 interferon-related genes. Conclusion: HMGB1-induced melanocyte signaling was well evaluated using RNA sequencing.
