Depletion of lncPRESS1 significantly induces expression of lineage-specific genesPAX6,HOXA1, andHOTAIRM1(ectoderm) andFOXA2(ecto/endo-derm), with less or no significant activation of genes associated with endo/mesoderm-specific lineages. In addition, Functional annotation analysis shows that lncPRESS1-activated genes have stem-cell-related functions, whereas genes repressed by lncPRESS1 are collectively represented by functional categories related to cell fate commitment and ectodermdifferentiation. Taken together, LncPRESS1 maintains the pluripotent status of hESCs(human Embryonic stem cells): depletion of lncPRESS1 compromises pluripotency and spontaneous differentiation. <ref name="ref1" />

Annotated Information

Name

LNCPRESS1:lncRNA p53 regulated and ESC associated 1

Gene ID: ENSG00000232301

Characteristics

LncPRESS1 is an intergenic transcript [1]. It is 756 nt in length and is multi-exonic [1].

Cellular Localization

LncPRESS1 is primarily localized to nucleus [1].

Function

Depletion of LncPRESS1 Affects Pluripotency[1].

LncPRESS1 is a p53-regulated transcript that maintains hESC (human embryonic stem cell) pluripotency in concert with core pluripotency factors [1]. It safeguards the hESC state by disrupting SIRT6, which maintains high levels of histone H3K56 and H3K9 acetylation at promoters of pluripotency genes [1].

Regulation

Nuclear lncPRESS1 is regulated by p53-dependent alterations in chromatin state during differentiation of hESCs [1].

Expression

Single-Cell Analyses Reveal Lineage-Specific Expression of p53-Regulated LncRNAs[1].

The expression of lncPRESS1 starts as early as the oocyte stage and is sustained to the morulae stage, with much higher expression in hESCs, suggesting that lncPRESS1 is highly enriched in the early stages of human embryonic development [1]. In addition, expression of lncPRESS1 is coordinated with pluripotency-specific genes and repression of lncPRESS1 during differentiation is largely controlled by p53 [1].
