Lipid metabolizing enzymes differ between preputial gland sebocytes and sebaceous gland sebocytes

Project description:Due to limited model systems for sebaceous glands we investigated potential suitability of preputial glands as model for sebaceous glands. We performed single-cell sequencing of murine preputial glands and back skin biopsies. This study revealed striking differences in lipid metabolizing enzyme expression and differentiation pathways found in sebocytes of the different tissues.

Laser Capture Microdissection-based RNAseq for Profiling Mouse and Human Sebaceous Gland Transcriptomes

Project description:We describe the use of laser capture microdissection (LCM) to isolate human and murine sebaceous glands (SGs) for transcriptomic analysis and publish this SG transcriptomic data for reference. We show that compared to whole skin RNA sequencing, LCM RNA sequencing allows for high resolution in identifying and describing SG genes at homeostasis. Lastly, we compare this LCM of sebaceous glands to published SG clusters from single cell RNA sequencing of skin, and show that we achieve greater resolution and depth with the LCM approach.

Gene expression signature of the three major epidermal differentiation compartments: interfollicular epidermis (IFE), hair follicle (HF) and sebaceous gland (SG).

Project description:There are multiple stem cells in adult mammalian epidermis, but the mechanisms controlling lineage specification are poorly understood. To identify gene expression signatures of the three major epidermal differentiation compartments we micro-dissected individual SG, IFE and HF from adult epidermis. The RNA was isolated from age and sex matched wild-type mice and performed transcriptome analysis with Affymetrix Exon microarrays We micro-dissected individual interfollicular epidermis (IFE), hair follicle (HF) and sebaceous gland (SG) from adult tail epidermis. The RNA was isolated from age and sex matched wild-type mice. Three biological replicates for each epidermal differentiation compartment were analyzed.

Sebaceous gland atrophy in psoriasis: An explanation for psoriatic alopecia?

Project description:In a transcriptome study of psoriatic (PP) vs. normal (NN) skin, we found a co-expressed gene module (N5) enriched 11.5-fold for lipid biosynthetic genes. We also observed fewer visible hairs in PP skin, compared to uninvolved (PN) or NN skin (p<0.0001). To ask whether these findings might be due to abnormalities of the pilosebaceous unit, we carried out 3D morphometric analysis of paired PP and PN biopsies. Sebaceous glands (SG) were markedly atrophic in PP vs. PN skin (91% average reduction in volume, p=0.031). Module N5 genes were strongly downregulated in PP vs. NN skin (fold-change [FC] < 0.25, 44.4-fold), and strongly up-regulated in sebaceous hyperplasia (SH, FC > 4, 54.1-fold). The intersection of PP-downregulated and SH-upregulated gene lists generated a gene expression signature consisting solely of module N5 genes, whose expression in PP vs. NN skin was inversely correlated with the signature of IL17-stimuated keratinocytes. Despite loss of visible hairs, morphometry identified elongated follicles in PP vs. PN skin (average 1.7 vs. 1.2 Jm, p=0.020). These results document SG atrophy in non-scalp psoriasis, identify a cytokine-regulated set of SG signature genes, and suggest that loss of visible hair in PP skin may result from abnormal SG function. Gene expression was compared between sebaceous hyperplasia lesions (n = 5) and normal skin (n = 3) from control subjects.

Aldehyde oxidase 4 (Aox4) knockout effect on Harderian Gland (HG), White Adipose Tissue(WADT) and Liver (LIV)

Project description:The mouse aldehyde oxidase, Aox4 (aldehyde oxidase 4), is a molybdo-flavoenzyme. Harderian glands are the richest source of Aox4, although the protein is detectable also in sebaceous glands, epidermis and other keratinized epithelia. We performed whole genome gene expression experiment on Harderian Gland, White Adipose Tissue and Liver of WT and Aox4-/- animals.

Transcription profiling of Lgr6+ keratinocyte populations in the epidermis and hair follicle

Project description:RNA sequencing was performed on sorted populations of Lgr6-positive and Lgr6-negative keratinocytes from the interfollicular epidermis and the hair follicle/sebaceous gland, in order to determine the compartment-specific expression signatures of Lgr6+ progenitor cells.

Long-acting immune responses including plasma cells and alteration of sebaceous glands cause atrophic scar formation in acne patients

Project description:Background: Possible outcomes of acne lesions are atrophic scars which may cause serious physical and psychological distress. Current treatments of post-acne scarring remain difficult and often require invasive procedures. Pathophysiological studies on acne scaring investigated only the first week of papule life. Objectives: Study the pathophysiology of atrophic acne scar formation to identify molecular and cellular pathways that can lead to new therapies for the prevention of acne scarring. Methods: Large-scale gene expression profiling of uninvolved acne skin and acne papules of 48 hours and 3 weeks of age, respectively, of both, scar-prone (SP) and non-scar-prone (NSP) patients was performed. Immunohistochemistry techniques were applied to confirm transcriptomics results on the protein and cellular level. Results: Gene expression and immunohistochemistry analyses showed a very similar immune response in 48 hours-old papules in SP and NSP populations characterized by elevated numbers of T cells, neutrophils and macrophages. However, only in SP patients the immune response persisted in 3 week-old papules, and was characterized by an important infiltrate of B cells. Transient down-modulation of genes related to lipid metabolism was observed in 48 hours-old papules in NSP patients, followed by normalization of gene expression levels after 3 weeks. In contrast, in SP patients a drastic reduction of lipid metabolizing enzymes was observed in 3 week-old papules, suggesting irreversible modifications. The affected lipid metabolism genes were found preferentially expressed in human sebaceous glands, pointing to a destruction of sebaceous gland structures after 3 weeks of inflammatory remodelling in SP acne patients.
