Project description:There is an absolute requirement of Pax7 for the normal function of MuSCs during regenerative myogenesis in skeletal muscle at any stage of life. Here using RNA-seq, H3K27ac and Pax7 ChIP-seq, we discover PAM-1 (Pax7 Associated Muscle lncRNA) that is enriched in activated skeletal muscle satellite cells (ASCs) 24 and 48 hours after activation. Knockdown of PAM-1 reduces proliferating Pax7+Myod+ ASCs number, while overexpression of PAM-1 increases ASCs number. Mechanistically, PAM-1 is located on ASCs and myoblast specific super-enhancer (SE), and we categorize it as seRNA. Through a series of multiomics analysis of PAM-1 interactome in myoblast including PAM-1-DNA interaction by ChIRP-seq, PAM-1 SE-DNA interaction by 4C-seq, PAM-1-protein interaction by mass spectrometry and ChIP-seq, we identify a novel class of transcriptional regulation that seRNA PAM-1 interacts with RNA binding protein Ddx5 and tethers PAM-1 SE to regulate inter-chromosomal targets Timp2. Altogether, our findings identify PAM-1 is driven by Pax7 in ASC and myoblast to regulate myogenic activation through binding with Ddx5 and targeting Timp2.

Project description:Background: Palmitic acid (PAM) can be provided in the diet or synthesized via de novo lipogenesis (DNL) primarily from glucose. Preclinical work on the origin of brain PAM during development is scarce and contrasts results on the origin of adult brain PAM. Here, we utilize naturally occurring carbon isotope ratios (13C/12C; δ13C) and RNA sequencing to uncover the origin of brain PAM, and pathways involved in maintaining brain PAM, respectively, during development. maintaining brain PAM, respectively, during development. Methods: Dams were equilibrated onto diets low (<2%), medium (47%) or high (>95%) in PAM prior to breeding. Dietary PAM was depleted in δ13C, while dietary sugars were enriched. Offspring stayed on the respective dam diet and were euthanized at postnatal day 0, 10, 21, and day 35. Pup liver and brain fatty acids were quantified, after which, tissue δ13C-PAM was measured by compound specific isotope analysis. Day 35 tissue RNA was sequenced on a NovaSeq S4 Flowcell. Results: Although PAM levels in the liver reflected levels of dietary PAM, PAM was maintained in total and individual brain phospholipid fractions across diet groups at all timepoints. Tissue δ13C-PAM was enriched overall and augmented in mice fed low PAM, compared to medium and high PAM suggesting that DNL from dietary sugars maintained the majority of the brain PAM pool. Furthermore, DNL pathways were upregulated in mice fed low compared to high PAM in the liver, but not the brain at day 35. Conclusions: Lipogenesis from dietary sugars maintains the majority of brain PAM during development and is augmented in mice fed low PAM from birth. Importantly, hepatic lipogenesis from dietary sugars determines PAM availability to the developing brain when low in the diet – a compensatory mechanism identified to maintain total brain PAM pools compared to periphery which ultimately suggests an importance of brain PAM regulation during development.

Project description:PKR-like kinase (PERK) plays a significant role in inducing angiogenesis in various cancer-types including glioblastoma. Mass spectrometry screen on conditioned media from LN308 glioblastoma cell line treated with hypoxia revealed Peptidylglycine α-amidating monooxygenase (PAM) as a potential target inducing angiogenesis. PERK is found to be regulating PAM at mRNA level. PERK activation via CCT020312 (PERK activator) also increased the cleavage and thus the generation of sfCD domain of PAM in an oxygen-independent manner which acts as a signaling molecule from cytoplasm to the nuclei. PERK was found interacting with PAM in immuno-precipitation experiments suggesting a possible involvement in the generation of the PAM sfCD domain. Knockdown of PERK or PAM in LN308 cells reduced the formation of tubes by HUVECs in vitro. In vivo data also highlighted the importance of PAM in growth of glioblastoma where reduction of PAM expression in engrafted tumor significantly increased the survival in mice. In summary, PAM acts as a potential target for therapy against angiogenesis in glioblastoma.

Project description:We generated single-cell RNAseq profiles of 143 microglia, sorted in the gate CD45lowCD11+Gpnmb+Clec7a+, from postnatal day 7 cerebellum to validate the newly identified “proliferative region-associated microglia (PAM)” (Gpnmb and Clec7a are PAM surface markers). Single cells were FACS index sorted followed by Smart-seq2 library preparation and Illumina Nextseq (sequence depth > 1 million per cell). These cells showed characteristic PAM gene expression and clustered together with other PAM cells sequenced in the same study.

Project description:A key limitation of the commonly-used CRISPR enzyme S. pyogenes Cas9 is the strict requirement of an NGG protospacer-adjacent motif (PAM) at the target site, which reduces the number of accessible genomic loci. This constraint can be limiting for genome editing applications that require precise Cas9 positioning. Recently, two Cas9 variants with a relaxed PAM requirement (NG) have been developed (xCas9 and Cas9-NG) but their activity has been measured at only a small number of endogenous sites. Here we devised a high-throughput Cas9 pooled competition screen to compare the performance of both PAM-flexible Cas9 variants and wild-type Cas9 at thousands of genomic loci and across 3 modalities (gene knock-out, transcriptional activation and suppression). We show that PAM flexibility comes at a substantial cost of decreased DNA targeting and cutting. Of the PAM-flexible variants, we found that Cas9-NG outperforms xCas9 regardless of genome engineering modality or PAM. Finally, we combined xCas9 mutations with those of Cas9-NG, creating a stronger transcriptional modulator than existing PAM-flexible Cas9 variants.
