Transcriptomes of human primary skin fibroblasts reveal age-associated mRNAs and long noncoding RNAs

ABSTRACT: Changes in the transcriptomes of human tissues with advancing age are poorly cataloged. Here, we set to identify the coding and long noncoding RNAs present in cultured primary skin fibroblasts collected from 82 healthy individuals across a wide age spectrum (22 to 89 years old) who participated in the GESTALT (Genetic and Epigenetic Signatures of Translational Aging Laboratory Testing) study of the National Institute on Aging, NIH. Using high-throughput RNA sequencing and a linear regression model, we identified 1,437 coding RNA (mRNA) and 1,177 linear and circular long noncoding (lncRNA) that were differentially abundant as a function of age. GSEA analysis revealed select transcription factors implicated in coordinating the transcription of subsets of differentially abundant mRNAs, while LncSEA identified RNA-binding proteins predicted to contribute to the age-associated lncRNA profiles. In sum, we report age-associated changes in the global transcriptome, coding and noncoding, from healthy human skin fibroblasts, and propose that they might serve as biomarkers and therapeutic targets in aging skin.

Human skin fibroblast proteome in healthy aging

Project description:The changes in the proteome of different human tissues with advancing age are poorly characterized. Here, we studied the proteins present in skin fibroblasts collected from 82 healthy individuals across a wide age spectrum (22 to 89 years old) who participated in the GESTALT (Genetic and Epigenetic Signatures of Translational Aging Laboratory Testing) study of the National Institute on Aging, NIH. Proteins were extracted from lysed fibroblasts and subjected to liquid chromatography-mass spectrometry analysis, and the expression levels of 9341 proteins were analyzed by linear regression models. Several differentially expressed proteins were implicated in processes that change with age, including autophagy, scavenging of reactive oxygen species (ROS), ribosome biogenesis, DNA replication, and DNA repair. Changes on these prominent pathways were further assessed using molecular and cell-culture approaches. Our study establishes a framework of the global proteome governing the homeostasis of the aged skin.

Molecular Rejuvenation of Gene Expression Pattern of Photoaged and Intrinsically Aged Human Skin by Broadband Light Treatment

Project description:Studies in model organisms suggest that aged cells can be functionally rejuvenated, but whether this concept applies to human skin is unclear. Here we apply deep sequencing of RNA 3' ends ("3-seq") to discover the gene expression program associated with human photoaging and intrinsic skin aging (collectively termed "skin aging") and the impact of broadband light (BBL) treatment. We find that skin aging was associated with the significantly altered expression level of 2,265 coding and noncoding RNAs, of which 1,293 became "rejuvenated" after BBL treatment, i.e. more similar in expression level of youthful skin. Rejuvenated genes (RGs) included several known key regulators of organismal longevity and their proximal long non-coding RNAs. Skin aging is not associated with systematic changes in 3' end mRNA processing. Hence, BBL treatment can restore the gene expression pattern of photoaged and intrinsically aged human skin to resemble young skin. In addition, our data reveals a novel set of targets that may lead to new insights into the human skin aging process. Examination of broadband light treated and untreated human skin transcriptomes of 5 women aged 50 years or more. They were compared to the skin transcriptomes of 5 young women aged 30 years or less.

Genome-wide analysis of long non-coding RNA (lncRNA) profiles in leg muscle of Xinghua Chickens.

Project description:We have used RNA-seq to examine long non-coding RNA (lncRNA) and mRNA from rRNA depleted in chicken leg musle of three different development stages (11 embryo age, 16 embryo age, and 1 days post hatch). Our study reveals the prevalence of lncRNA in chicken, and has identified lncRNA differentially abundant in different stage of embryonic skeletal muscle, suggesting its important functions during poultry muscle development.

Identification of proteins that interact with the lncRNA Sarrah

Project description:Long non-coding RNAs (lncRNAs) contribute to (patho)physiological processes in the heart. Aging is the major risk factor for cardiovascular disease. Apoptosis of individual cardiomyocytes is one of the underlying causes for age-related cardiac dysfunction. Here, we identified the lncRNA Sarrah that is regulated during aging in cardiomyocytes and show that it has a protective effect on the myocardium. We used an RNA pulldown approach to identify proteins interacting with endogenous Sarrah to determine the mechanism by which Sarrah induces a cardioprotective gene expression pattern.

Age and poverty status alter the coding and noncoding transcriptome [White]

Project description:Emerging evidence indicates that noncoding RNAs play important regulatory roles during aging and the development of chronic disease. The functional roles of long noncoding RNAs (lncRNAs) in physiology and disease are under intense examination. However, little is known about lncRNAs in the context of human aging and socio-environmental conditions. Microarray profiling of lncRNAs and mRNAs in young and old white and African American (AA) males living above or below poverty revealed robust changes in both lncRNAs and mRNAs with age and poverty status in white males, but not in AA males. We validated the changes in lncRNAs in an expanded cohort; CDT-3247F14.2, GAS5, H19, TERC and MEG3 changed significantly with age, whereas AK022914, GAS5, KB-1047C11.2, MEG3 and XLOC_003262 changed significantly with poverty. Pathway analysis revealed that mitochondrial function and response to DNA damage and stress were enriched in younger individuals. Pathways of response to stress, viral infection, and immune signals were enriched in individuals living above poverty. These data show that both human age and a marker of social adversity influence lncRNA expression patterns. These data may provide insight into the molecular pathways underlying aging and social factors that affect disparities in aging and disease.

Evx1as and EVX1 knockouts by CRISPR

Project description:We report that long noncoding RNAs contribute to transcription and developmental process. Thousands of lncRNAs have been identified in the whole genome, and tend to located closely to protein-coding genes. To study position relationship between lncRNA and protein-coding genes, we classified all of lncRNA to several subgroups based on the genome position with their coding neighbors. XH, the head to head subgroup is associated with transcription and development in GO analysis. Here, we knockdown serveral XH lncRNA by shRNA in embryonic stem cells and induce nondirectional differnetiation by removing LIF or neural differnetiation by RA. Knockdown of XH lncRNAs led to uniform downregulation of nearby coding genes, and form regulatory circuits with its nearby coding genes to fine-tune embryonic lineage development. In addition, we also knockout one lncRNA-Evx1as and its nearby protein-coding gene-EVX1 by CRISPR, and get similar results as knockdown.We propose that XH lncRNA may function primarily as 'cis-regulators' of the expression of nearby protein-coding genes, and tend to participate in transcriptional or development regulations as their coding neighbors. All RNA-seq(s) were designed to reveal the differentially expressed genes between wild-type and XH lncRNA knockdown/knockout ESCs during differentiation.

Comparison of expression profile between fibroblasts taken from young (23 years old) and aged (70 years old) donors

Project description:Several features differentiate aged cells from young cells, many of which are due to changes in gene expression during the aging process. The mechanisms of altered gene expression in aging cells remain incompletely understood, and we hypothesized that long non-coding (lnc) RNAs mediate at least some of these changes. To determine candidate lncRNAs which are associated with aging process, we screened for alterations in lncRNA expression with aging in skin fibroblasts. Twenty-eight lncRNAs were found to be expressed more than 2-fold in aged fibroblasts, and thirty-five lncRNAs expressed less than 0.5-fold.
