N6-methyladenosine Modification of lncRNA Pvt1 Governs Epidermal Stemness

Project description:Dynamic chemical modifications of RNA represent novel and fundamental mechanisms that regulate stemness and tissue homeostasis. Rejuvenation and wound repair of mammalian skin are sustained by epidermal progenitor cells, which are localized within the basal layer of the skin epidermis. N6-methyladenosine (m6A) is one of the most abundant modifications found in eukaryotic mRNA and lncRNA (long non-coding RNA). In this report, we survey changes of m6A RNA methylomes upon epidermal differentiation, and identify Pvt1, a lncRNA whose m6A modification is critically involved in sustaining stemness of epidermal progenitor cells. With genome-editing and a mouse genetics approach, we show that ablation of m6A methyltransferase or Pvt1 impairs the self-renewal and wound healing capability of skin. Mechanistically, methylation of Pvt1 transcripts enhances its interaction with MYC and stabilizes the MYC protein in epidermal progenitor cells. Our study presents a global view of epitranscriptomic dynamics that occur during epidermal differentiation and identifies the m6A modification of Pvt1 as a key signaling event involved in skin tissue homeostasis and wound repair.

Gene expression profile of primary epidermal keratinocytes (HEKs) stimulated with lawsone

Project description:The study aimed to interrogate whether the 1,4-naphtoquinone derivative lawsone activates the aryl hydrocarbon receptor (AhR) downstream transcriptional program in keratinocytes and is capable of modulating skin homeostasis. The study has been performed on human primary epidermal keratinocytes (HEKs), which represent the first line of defense against exogenous molecules. HEK cells were treated with the vehicle control DMSO (control), stimulated with lawsone or with the TLR2 ligand Pam2CSK4. Transcriptional profiles of HEK cells were studied to investigate the regulation of AhR -related genes, Nrf2-related genes and epidermal differentiation and keratin genes. We demonstrated that lawsone was sensed by keratinocytes and activated AhR. In particular, lawsone efficiently activated the transcriptional program of AhR and promoted keratinocyte differentiation.

N6-Methyladenosine methylation profile in rat H9C2 cardiomyocytes under the hypoxic stress

Project description:Hypoxia as a crucial pathogenesis factor usually results in huge harmful effects on cardiac injury and dysfunction. In our previous study (PMID: 33294289), We observe a series of differential expressed genes between transcription and translation, which may be attributed to the hypoxia-specific binding affinity of Nuclear cap-binding subunit 3 (NCBP3) at 5’ un-translation region of target genes. But the underlying molecular mechanism of NCBP3 for gene translation modulation remains unclear. Here, we conducted RIP-seq of N6-Methyladenosine methylation in H9C2 cells with the conditions of normoxic, hypoxic and with additional NCBP3 knockdown.

N6-methyladenosine Modulates Messenger RNA Translation Efficiency

Project description:N6-methyladenosine (m6A) is the most abundant internal messenger (mRNA) modification in mammalian mRNA. This modification is reversible and non-stoichiometric, which potentially adds an additional layer of variety and dynamic control of mRNA metabolism. The m6A-modified mRNA can be selectively recognized by the YTH family “reader” proteins. The preferential binding of m6A-containing mRNA by YTHDF2 is known to reduce the stability of the target transcripts; however, the exact effects of m6A on translation has yet to be elucidated. Here we show that another m6A reader protein, YTHDF1, promotes ribosome loading of its target transcripts. YTHDF1 forms a complex with translation initiation factors to elevate the translation efficiency of its bound mRNA. In a unified mechanism of translation control through m6A, the YTHDF2-mediated decay controls the lifetime of target transcripts; whereas, the YTHDF1-based translation promotion increases the translation efficiency to ensure effective protein production from relatively short-lived transcripts that are marked by m6A. PAR-CLIP and RIP was used to identify YTHDF1 binding sites followed by ribosome profling and RNA seq to assess the consequences of YTHDF1 siRNA knock-down
