Project description:To explore the biological changes of keratinocytes in condyloma acuminata (CA) warts, we performed mRNA and lncRNA expression profiling of keratinocytes from normal skins and warts of condyloma acuminata patients to compare the gene expression.

Project description:The morphology and the behavior of skin and oral tissue keratinocytes are different. One significant dissimilarity between the two sites is the response to injury. Oral and skin keratinocytes have intrinsic differences in the response to injury and such differences are reflected in gene expression profiles. We used microarrays to investigate differences in global gene expression patterns between baseline skin and oral epithelium sheets without their underlying connective tissue. Paired skin and oral epithelium was separated from the dermis for RNA extraction and hybridization on Affymetrix microarrays. Skin epidermal tissues were obtained from the tail of mice and oral epidermal tissues were obtained from the hard palate. Enzymatically isolated epithelium was used for analysis.

Project description:Compared to skin wounds, oral mucosal wounds heal more rapidly with less inflammation, faster re-epithelialization, and minimal scarring. One cell type that may be a differentiating factor is keratinocytes. Using immortalized skin and oral keratinocytes, HaCaT and TIGK, respectively, we found that oral keratinocytes have an enhanced migratory and proliferative capacity. To examine the transcriptomic differences that underlie the improved healing abilities of oral keratinocytes, we generated an RNA-sequencing (RNA-seq) gene expression dataset utilizing HaCaT and TIGK. Differentially expressed genes (DEGs) were identified between HaCaT and TIGK at baseline and throughout the injury response. Gene Ontology (GO) or Reactome enrichment analysis was performed to understand the biological significance of DEGs. Processes related to inflammation and migration were uniquely enriched in TIGK. Additionally, TIGK retained its enhanced migratory capacity when grown on various basement membrane (BM) and extracellular matrix (ECM) substrates. This may be due to the differential expression of matrix metalloproteinases (MMPs) and integrins between HaCaT and TIGK. We also identified genes differentially over or under-expressed in HaCaT and TIGK following injury when compared to each respective cell type’s unwounded gene expression levels. Lastly, we showed that the post-injury secretome of TIGK promotes keratinocyte migration. Our comparative analyses suggest specific transcriptomic differences between oral and skin keratinocytes at unwounded baseline and in response to injury may underlie the distinct wound healing phenotypes seen in these two tissues. This work also provides a source of HaCaT and TIGK gene expression data over healing that can be used for future analyses.

Project description:The epidermis of skin and oral mucosa is constantly exposed to various environmental stimuli, including temperature changes. In particularly extreme conditions, such as excess heat or cold, significant injury may occur. Oral and skin keratinocytes exhibit tissue-specific differences in wound healing outcomes and the transcriptomic response to injury. This study investigated if skin and oral keratinocytes also have differential responses to heat and cold-induced injury. Oral keratinocytes (TIGK) were found to exhibit an enhanced viability following heat-induced injury compared to skin keratinocytes (HaCaT). However, there were no discernible differences between skin and oral keratinocyte viability following cold-induced injury. To examine the transcriptomic differences between skin and oral keratinocytes in response to temperature-induced injury, we generated an mRNA-sequencing gene expression dataset. Differentially expressed genes (DEGs) including heat shock proteins (HSPs) were identified between HaCaT and TIGK at baseline (37°C) and after heat (60°C) or cold-induced (-25°C) injury. Our comparative analyses suggest that skin and oral keratinocytes exhibit transcriptomic differences at baseline and in their responses to heat or cold exposure. The enhanced heat tolerance of TIGK relative to HaCaT may be due to an advantageous expression of a subset of HSPs at baseline in TIGK. Our work also provides a source of skin and oral keratinocyte gene expression data following heat and cold-induced injury that can be used for future analyses.

Project description:Dysregulation and abnormal expression of inflammatory mediators by keratinocytes promote the pathogenesis of the skin inflammation such as allergic contact dermatitis (ACD). High-mobility group box 1 (HMGB1) protein, a prototypical damage-associated molecular pattern (DAMP), that is expressed in the nucleus but released extracellularly upon inflammation has gained attention as an accelerator for skin inflammation. However, in vivo role of HMGB1 in ACD and other skin disorders remains to be elusive. In this study, we generated conditional knockout mice in which HMGB1 is deleted in keratinocytes and examined its role in skin inflammation models including 2,4-dinitrofluorobenezene (DNFB)-induced ACD. Unexpectedly, deletion of HMGB1 in keratinocytes exacerbated skin inflammation, accompanied by increased ear thickening. Elevated mRNA expression of interleukin-24 (IL-24), a known cytokine which promotes the pathogenesis of ACD, was also observed in the skin lesion of the mice. In accordance with above observations, both constitutive and IL-4-induced Il24 mRNA expression in vitro was augmented in hmgb1-deficient primary mouse keratinocytes and keratinocyte cell line PAM212 cells. Chromatin immunoprecipitation (ChIP) analysis revealed increased binding of tri-methyl histone H3 (lys4) (H3K4me3), a well-known histone mark for transcription active genes, to the promoter region of the Il24 gene in the hmgb1-deficient cells. ChIP-sequencing data also showed broad changes of H3K4me3 mark in the cells. Thus, HMGB1 in the nucleus dictates histone modifications. In conclusion, our study demonstrated a key role for HMGB1 in keratinocytes in the maintenance of chromatin modification status to protect from exuberant skin inflammation.

Project description:AbstractNo clear guidelines are available for the management of pregnant women with condyloma acuminata, a human papillomavirus-associated benign neoplasm that develops in the genital tract. We performed a systematic review to gain a better understanding of the management of condyloma acuminata during pregnancy. In this review, we mainly focused on treatments. We searched PubMed, Google Scholar, and Web of Science to identify studies on the treatment of condyloma acuminata during pregnancy. Thirty articles met the inclusion criteria. The treatment methods described in the literature were laser therapy, cryotherapy, imiquimod, photodynamic therapy, trichloroacetic acid, and local hyperthermia. The most effective treatment remains unclear. Various factors must be considered when deciding how to treat. Based on our assessment of the literature, we recommend cryotherapy as the first-choice treatment and laser therapy as the second-choice treatment. Imiquimod can be considered in cases such as extensive condyloma acuminata that is not easily treated by cryotherapy or laser therapy. In such cases, sufficient informed consent must be obtained from the patient. Cryotherapy, laser therapy, and imiquimod have been administered during all 3 trimesters with no severe adverse effects, but we cautiously recommend reserving laser therapy until the third trimester because of the lower risk of recurrence before delivery. There are still many unclear points regarding the management of condyloma in pregnancy, and further research is needed.
