Identification of genes involved in sebaceous gland carcinoma of the eyelid

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.

Differentially expressed miRNAs for sebaceous gland carcinoma of the eyelid and TP53 mutation

Project description: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.

Heparan sulfate regulates hair follicle and sebaceous gland morphogenesis and homeostasis.

Project description:Hair follicle (HF) morphogenesis and cycling are a result of intricate autonomous epithelial-mesenchymal interactions. Once the first HF cycle is complete it repeatedly undergoes cyclic transformations. Heparan sulfate (HS) proteoglycans are found on the cell surface and in the extracellular matrix where they influence a variety of biological processes by interacting with physiologically important proteins, such as growth factors. Inhibition of heparanase (an HS endoglycosidase) in in vitro cultured HFs has been shown to induce a catagen-like process. Therefore, this study aimed to elucidate the precise role of HS in HF morphogenesis and cycling. An inducible tetratransgenic mouse model was generated to excise exostosin glycosyltransferase 1 (Ext1) in keratin 14-positive cells from P21. Interestingly, EXT1(StEpi?/StEpi?) mice presented solely anagen HFs. Moreover, waxing the fur to synchronize the HFs revealed accelerated hair regrowth in the EXT1(StEpi?/StEpi?) mice and hindered cycling into catagen. The ablation of HS in the interfollicular epidermal cells of mature skin led to the spontaneous formation of new HFs and an increase in Sonic Hedgehog expression resembling wild-type mice at P0, thereby indicating that the HS/Sonic Hedgehog signaling pathway regulates HF formation during embryogenesis and prevents HF formation in mature skin. Finally, the knock-out of HS also led to the morphogenesis and hyperplasia of sebaceous glands and sweat glands in mature mice, leading to exacerbated sebum production and accumulation on the skin surface. Therefore, our findings clearly show that an intricate control of HS levels is required for HF, sebaceous gland, and sweat gland morphogenesis and HF cycling.

BLIMP1 is required for postnatal epidermal homeostasis but does not define a sebaceous gland progenitor under steady-state conditions.

Project description:B-lymphocyte-induced nuclear maturation protein 1 (BLIMP1) was previously reported to define a sebaceous gland (SG) progenitor population in the epidermis. However, the recent identification of multiple stem cell populations in the hair follicle junctional zone has led us to re-evaluate its function. We show, in agreement with previous studies, that BLIMP1 is expressed by postmitotic, terminally differentiated epidermal cells within the SG, interfollicular epidermis, and hair follicle. Epidermal overexpression of c-Myc results in loss of BLIMP1(+) cells, an effect modulated by androgen signaling. Epidermal-specific deletion of Blimp1 causes multiple differentiation defects in the epidermis in addition to SG enlargement. In culture, BLIMP1(+) sebocytes have no greater clonogenic potential than BLIMP1(-) sebocytes. Finally, lineage-tracing experiments reveal that, under steady-state conditions, BLIMP1-expressing cells do not divide. Thus, rather than defining a sebocyte progenitor population, BLIMP1 functions in terminally differentiated cells to maintain homeostasis in multiple epidermal compartments.

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.

Epigenomic profiling of hair follicle stem cells identifies PRDM16 as a regulator of sebaceous gland homeostasis [RNA-seq]

Project description:The epidermis consists of different compartments such as the hair follicle (HF), sebaceous gland (SG) and interfollicular epidermis (IFE), each containing distinct stem cell (SC) populations. However, with the exception of the SCs residing within the HF bulge, other epidermal SC populations remain poorly characterized at the molecular level. Here we used an epigenomic strategy that combines H3K27me3 ChIP-seq and RNA-seq profiling to identify major regulators of HFSC located outside the bulge. When applied to the bulk of HFSC isolated from mouse skin our approach identified both previously known and potentially novel non-bulge HFSC regulators. Among the latter, we found that PRDM16 was preferentially expressed within the Junctional Zone (JZ). To investigate PRDM16 function within the JZ SCs, we generated an epidermal-specific Prdm16 Knock-out mouse model (K14-Cre-Prdm16fl/fl). Notably, although these K14-Cre-Prdm16fl/fl mice did not show any major skin or hair abnormalities, the homeostasis of the SG was clearly compromised. Namely, PRDM16 deficient mice displayed enlarged SGs and excessive sebum production, thus resembling some of the features associated with certain human conditions (i.e. acne, sebaceous hyperplasia). Overall, our study provides a list of putative novel regulators of HFSC outside the bulge and identifies PRDM16 as a major regulator of SG homeostasis.
