The long non-coding RNA LINC00941 and SPRR5 are novel regulators of human epidermal homeostasis

Project description:Several long non-coding RNAs (lncRNAs) act as regulators of cellular homeostasis; however, few of these molecules were functionally characterized in a mature human tissue environment. Here, we report that the lncRNA LINC00941 is a crucial regulator of human epidermal homeostasis. LINC00941 is enriched in progenitor keratinocytes and acts as a repressor of keratinocyte differentiation. Furthermore, LINC00941 represses SPRR5, a previously uncharacterized molecule, which functions as an essential positive regulator of keratinocyte differentiation. Interestingly, 54.8% of genes repressed in SPRR5 deficient epidermal tissue are induced in LINC00941 depleted organotypic epidermis, suggesting a common mode of action for both molecules.

The long non-coding RNA LINC00941 regulates human epidermal homeostasis through interaction with the MTA2/NuRD complex

Project description:Numerous long non-coding RNAs (lncRNAs) were shown to have functional impact on cellular processes, such as human epidermal homeostasis, but for only a few the mode of action has been elucidated. Here, we report that lncRNA LINC00941 controls keratinocyte differentiation on a global level through association with the MTA2/NuRD complex, one of the major chromatin remodelers in cells. LINC00941 was found to interact with NuRD-associated MTA2, suppressing the expression of the transcription factor EGR3, a regulator of epidermal differentiation. Both, LINC00941 and the MTA2/NuRD complex are enriched in non-differentiated keratinocytes and repress the expression of differentiation genes through epigenetic silencing of EGR3, consequentially repressing premature differentiation of human progenitor cells.

A genome-wide long noncoding RNA CRISPRi screen identifies PRANCR as a novel regulator of epidermal homeostasis

Project description:Long noncoding RNAs (lncRNAs) are a major component of the noncoding genome, but their functions in human development and disease are still incompletely understood. CRISPR interference screens allow for systematic identification of functional lncRNAs that regulate fundamental biological processes such as tissue development and homeostasis. We identified 2,263 lncRNAs transcribed in human epidermis, and performed a comprehensive CRISPR interference screen against all these elements in primary human epidermal progenitors. Our screen identified 209 lncRNAs controlling epidermal progenitor renewal, with the majority (94%) being positive regulators of proliferation. To validate the results, we performed deeper characterization of a novel lncRNA identified from this screen, PRANCR (LINC01481), using RNA interference-mediated transcript knockdown and phenotype analysis in organotypic human tissue. PRANCR depletion inhibited progenitor proliferation through a G2/M cell cycle arrest, reduced clonogenic potential, and impaired functional epidermal stratification. Transcriptome and computational analysis indicated that PRANCR governs progenitor renewal by controlling the expression of 1,136 genes in trans, in part via the p53-E2F4-CHR pathway. This pathway controls the expression of G2/M cell cycle genes and is a novel mechanism of regulating cell proliferation in epidermal progenitors.
