Project description:This study explores whether HuD could bind to and regulate the expression circRNAs from genes associated with neuronal development and synaptic plasticity circRNAs bound to HuD were isolated from the striatum of HuD-OE mice by RNA immunoprecipitation (RIP) as described in Bolognani et al, 2010 (https://doi.org/10.1093/nar/gkp863) using Dynabeads® (Thermo Fisher Scientific) coated with mouse monoclonal anti-myc tag antibody (9B11; Cell Signalling Technology Inc.) specifically recognizing myc-tagged HuD transgenic protein expressed in HuD-OE as described before (Bolognani et al., 2010; Zimmerman et al., 2020). Controls for RIP assays were performed using either non-immune IgG and HuD-OE tissue or the myc-tag antibody and wild type (WT) tissue.

Project description:Fibrosis, neurodegeneration, and cerebral angiomatosis (FINCA) (OMIM 618278) is a rare infantile-onset disease caused by variants in NHL repeat containing 2 (NHLRC2) gene. NHLRC2 is essential for mouse gastrulation (Hiltunen et al., 2022). Here, RNA sequencing was performed on four wild type (WT), four homozygous C57BL/6NCrl-Nhlrc2em1Rthl (FINCA disease causing variant) (Hiltunen et al., 2020), and four homozygous C57BL/6NCrl-Nhlrc2tm1a(KOMP)Wtsi (Nhlrc2 knock out) mouse embryonic stem cell lines each established from individual mouse embryos by the 2i method (Nichols et al., 2009). FINCA variant mESCs express the full length endogenous Nhlrc2 mRNA modified to containing a c.442G > T variant leading to p.Asp148Tyr as well as a silent c.408C>A for genotyping purposes (Hiltunen et al., 2020). In the Nhlrc2 KO mESCs the transcription is halted by a trapping cassette between exons 4 and 5 (Hiltunen et al., 2022; Skarnes et al., 2011). References Hiltunen, A. E., Kangas, S.

Project description:While DNA methylation is an important gene regulatory mechanism in mammals (Razin and Riggs 1980; Moore, Le, and Fan 2013), its function in arthropods remains poorly understood. Studies in eusocial insects have argued for its role in caste development by regulating gene expression and splicing (Elango et al. 2009; Lyko et al. 2010; Bonasio et al. 2012; Flores et al. 2012; Foret et al. 2012; Li-Byarlay et al. 2013; Marshall, Lonsdale, and Mallon 2019; Shi et al. 2013)(Alvarado et al. 2015; Kucharski et al. 2008). However, such findings are not always consistent across studies, and have therefore remained controversial (Arsenault, Hunt, and Rehan 2018; Cardoso-Junior et al. 2021; Harris et al. 2019; Herb et al. 2012; Libbrecht et al. 2016; Oldroyd and Yagound 2021b; Patalano et al. 2015). Here we use CRISPR/Cas9 to mutate the maintenance DNA methyltransferase DNMT1 in the clonal raider ant, Ooceraea biroi. Mutants have greatly reduced DNA methylation but no obvious developmental phenotypes, demonstrating that, unlike mammals (Brown and Robertson 2007; En Li, Bestor, and Jaenisch 1992; Jackson-Grusby et al. 2001; Panning and Jaenisch 1996), ants can undergo normal development without DNMT1 or DNA methylation. Additionally, we find no evidence of DNA methylation regulating caste development. However, mutants are sterile, while in wildtypes, DNMT1 is localized to the ovaries and maternally provisioned into nascent oocytes. This supports the idea that DNMT1 plays a crucial but unknown role in the insect germline (Amukamara et al. 2020; Arsala et al. 2021; Bewick et al. 2019; Schulz et al. 2018; Ventós-Alfonso et al. 2020; Washington et al. 2020).

Project description:S. aureus strain JKD6009 RNase III-HTF and USA300 RNase III-HTF were used in our study to capture the RNA-binding proteome in Staphylococcus aureus. Both strains were inoculated in TSB (Tryptone soya broth, Oxioid CM0129) and overnight cultured in 37°C, 200 rpm shaker. Strain JKD6009 RNase III-HTF was sub-cultured into 190 ml LPM (Coombes et al., 2004) (Low phosphate, low magnesium medium, 5 mM KCl, 7.5 mM (NH4)2SO4, 0.5 mM K2SO4, 8 µM MgCl2, 1 M KH2PO4, 16 mM Tris-HCl, 0.1% casamino acids, 0.3% Glycerol) and grew from OD600 0.01 to 1. Overnight cultures of USA300 RNase III-HTF was re-inoculated to 65 ml fresh TSB to OD600 0.05 and left to grow to an OD600 of ~3. Cells were then filtered through 0.45 µm filters using a vacuum filtration device (UVO3; (McKellar et al., JoVe 2020; Van Nues et al., Nature Communications 2017)) shifted to same volume of LPM medium for 15 min at 37ºC and UV irradiated in LPM in the Vari-X-linker (λ =254 nm) (https://www.vari-x-link.com; (McKellar et al., 2020; Van Nues et al., 2017)) with an energy dose of 2J/cm2. In total, 6 replicates were collected (three technical and two biological replicates) for each experiment.

Project description:CD47 is a transmembrane glycoprotein that is ubiquitously expressed in different organs and tissues (Barclay and Van den Berg 2014; Liu, et al. 2017). In the human immune system, CD47 interacts with some integrins, two counter-receptor signal regulator protein (SIRP) family members, and the secreted thrombospondin-1 (TSP1) (Barclay and Van den Berg 2014; Gao, et al. 2016; Kaur, et al. 2013; Oldenborg, et al. 2000). CD47 has two established roles in the immune system. The CD47-SIRPα interaction was identified as a critical innate immune checkpoint, which delivers an antiphagocytic signal to macrophages and inhibits neutrophil cytotoxicity (Martínez- Sanz, et al. 2021). Its interaction with inhibitory SIRPα is a physiological anti-phagocytic “don’t eat me” signal on circulating red blood cells that is co-opted by cancer cells (Matlung, et al. 2017). Many malignant cells overexpress CD47 (Betancur, et al. 2017; Chao, et al. 2011; Jaiswal, et al. 2009; Majeti, et al. 2009; Oronsky, et al. 2020; Petrova, et al. 2017). CD47/SIRPα-targeted therapeutics have been developed to overcome this immune checkpoint for cancer treatment (Kaur, et al. 2020; Matlung, et al. 2017). Secondly, engagement of CD47 on T cells by TSP1 regulates their differentiation and survival (Grimbert, et al. 2006; Lamy, et al. 2007) and inhibits T cell receptor signaling and antigen presentation by dendritic cells (DCs) (Kaur, et al. 2014; Li, et al. 2002; Liu, et al. 2015; Miller, et al. 2013; Soto-Pantoja, et al. 2014; Weng, et al. 2014). TSP1/CD47 signaling has similar inhibitory functions to limit NK cell activation (Kim, et al. 2008; Nath, et al. 2018; Nath, et al. 2019; Schwartz, et al. 2019) and IL1β production by macrophages (Stein, et al. 2016). CD47 is therefore a checkpoint that regulates both innate and adaptive immunity. The recent understanding of CD47 antagonism associated with increased antigen presentation by DCs (Liu, et al. 2016) and natural killer cell cytotoxicity (Nath, et al. 2019) contributes to the heightened interest in CD47 as a therapeutic target (Kaur, et al. 2020).

Project description:The plant pathogenic fungus Verticillium dahliae has homologs of the clock genes [Cascant-Lopez et al., 2020], which are well described in Neurospora crassa [Diernfellner et al., 2020]. In N. crassa, frequency (Frq) and the Frq-interacting RNA helicase (Frh) interact and form the Frq-Frh complex [Cheng et al., 2005]. Formation of this complex was described to be still possible but weakened by a single amino acid exchange of arginine 806 of Frh to histidine (Frh^R806H) [Shi et al., 2010; Conrad et al., 2016]. We found that both FRQ and wild-type FRH were required for enhanced conidiation and the light-dependent repression of microsclerotia formation in V. dahliae, but were dispensable for disease induction in tomato plants. Strikingly, the FRH^R806H mutant strain grew similar to the FRQ deletion strain, although transcript and protein levels of Frq were not significantly affected by the FRH^R806H mutation when compared with the wild-type. Therefore, we hypothesized that V. dahliae Frq and Frh form the Frq-Frh complex to regulate V. dahliae development, and that this complex formation is abolished upon the amino acid exchange in the Frh. By the use of protein pull-downs, potential interactions of Frh-GFP or Frh^R806H-GFP with Frq were investigated. While we found evidence for a direct interaction of Frh-GFP and Frq, no proteins were significantly co-enriched with Frh^R806H-GFP.
