Abstract
Although serine ADP-ribosylation (Ser-ADPr) by Poly(ADP-ribose)-polymerases is a cornerstone of the DNA damage response, how this regulates DNA repair and genome stability is unknown. Here, we exploit the ability to manipulate histone genes in Dictyostelium to identify that ADPr of the histone variant H3b at S10 and S28 maintains genome stability by integrating double strand break (DSB) repair with mitotic entry. Given the critical requirement for mitotic H3S10/28 phosphorylation, we develop separation of function mutations that maintain S10 phosphorylation whilst disrupting ADPr. Mechanistically, this reveals a requirement for H3bS10/28 ADPr in non-homologous end-joining by recruiting Ku to DSBs. Moreover, this also identifies H3bS10/S28 ADPr is critical to prevent premature mitotic entry with unresolved DNA damage, thus maintaining genome stability. Together, these data demonstrate how serine ADPr of histones coordinates DNA repair with cell cycle progression to maintain genome stability.

Abstract
The social amoeba Dictyostelium discoideum provides an excellent model for research across a broad range of disciplines within biology. The organism diverged from the plant, yeast, fungi and animal kingdoms around 1 billion years ago but retains common aspects found in these kingdoms. Dictyostelium has a low level of genetic complexity and provides a range of molecular, cellular, biochemical and developmental biology experimental techniques, enabling multidisciplinary studies to be carried out in a wide range of areas, leading to research breakthroughs. Numerous laboratories within the United Kingdom employ Dictyostelium as their core research model. This review introduces Dictyostelium and then highlights research from several leading British research laboratories, covering their distinct areas of research, the benefits of using the model, and the breakthroughs that have arisen due to the use of Dictyostelium as a tractable model system.

Abstract
Preserving genome integrity through repair of DNA damage is critical for human health and defects in these pathways lead to a variety of pathologies, most notably cancer. The social amoeba Dictyostelium discoideum is remarkably resistant to DNA damaging agents and genome analysis reveals it contains orthologs of several DNA repair pathway components otherwise limited to vertebrates. These include the Fanconi Anemia DNA inter-strand crosslink and DNA strand break repair pathways. Loss of function of these not only results in malignancy, but also neurodegeneration, immune-deficiencies and congenital abnormalities. Additionally, D. discoideum displays remarkable conservations of DNA repair factors that are targets in cancer and other therapies, including poly(ADP-ribose) polymerases that are targeted to treat breast and ovarian cancers. This, taken together with the genetic tractability of D. discoideum, make it an attractive model to assess the mechanistic basis of DNA repair to provide novel insights into how these pathways can be targeted to treat a variety of pathologies. Here we describe progress in understanding the mechanisms of DNA repair in D. discoideum, and how these impact on genome stability with implications for understanding development of malignancy.

Abstract
BACKGROUND INFORMATION Poly(ADP-ribose) polymerase-1 (PARP-1) has been attributed to varied roles in DNA repair, cell cycle, cell death, etc. Our previous reports demonstrate the role of PARP-1 during Dictyostelium discoideum development by its constitutive downregulation as well as by PARP-1 ortholog, ADP ribosyl transferase 1 A (ADPRT1A) overexpression. The current study analyses and strengthens the function of ADPRT1A in multicellular morphogenesis of D. discoideum. ADPRT1A was knocked out, and its effect was studied on cAMP signalling, chemotaxis and development of D. discoideum. RESULTS We report that ADPRT1A is essential in multicellular development of D. discoideum, particularly at the aggregation stage. Genetic alterations of ADPRT1A and chemical inhibition of its activity affects the intracellular and extracellular cAMP levels during aggregation along with chemotaxis. Exogenous cAMP pulses could rescue this defect in the ADPRT1A knockout (ADPRT1A KO). Expression analysis of genes involved in cAMP signalling reveals altered transcript levels of four essential genes (PDSA, REGA, ACAA and CARA). Moreover, ADPRT1A KO affects prespore- and prestalk-specific gene expression and prestalk tendency is favoured in the ADPRT1A KO. CONCLUSION ADPRT1A plays a definite role in regulating developmental morphogenesis via cAMP signalling. SIGNIFICANCE This study helps in understanding the role of PARP-1 in multicellular development and differentiation in higher complex organisms.

Abstract
The amoeba Dictyostelium discoideum is a single-cell organism that can undergo a simple developmental program, making it an excellent model to study the molecular mechanisms of cell motility, signal transduction, and cell-type differentiation. A variety of human genes that are absent or show limited conservation in other invertebrate models have been identified in this organism. This includes ADP-ribosyltransferases, also known as poly-ADP-ribose polymerases (PARPs), a family of proteins that catalyze the addition of single or poly-ADP-ribose moieties onto target proteins. The genetic tractability of Dictyostelium and its relatively simple genome structure makes it possible to disrupt PARP gene combinations, in addition to specific ADP-ribosylation sites at endogenous loci. Together, this makes Dictyostelium an attractive model to assess how ADP-ribosylation regulates a variety of cellular processes including DNA repair, transcription, and cell-type specification. Here we describe a range of techniques to study ADP-ribosylation in Dictyostelium, including analysis of ADP-ribosylation events in vitro and in vivo, in addition to approaches to assess the functional roles of this modification in vivo.

Site-specific ADP-ribosylation of histone H2B in response to DNA double strand breaks. Sci Rep 2017; 7:43750.

Abstract
ADP-ribosyltransferases (ARTs) modify proteins with single units or polymers of ADP-ribose to regulate DNA repair. However, the substrates for these enzymes are ill-defined. For example, although histones are modified by ARTs, the sites on these proteins ADP-ribosylated following DNA damage and the ARTs that catalyse these events are unknown. This, in part, is due to the lack of a eukaryotic model that contains ARTs, in addition to histone genes that can be manipulated to assess ADP-ribosylation events in vivo. Here we exploit the model Dictyostelium to identify site-specific histone ADP-ribosylation events in vivo and define the ARTs that mediate these modifications. Dictyostelium histones are modified in response to DNA double strand breaks (DSBs) in vivo by the ARTs Adprt1a and Adprt2. Adprt1a is a mono-ART that modifies H2BE18 in vitro, although disruption of this site allows ADP-ribosylation at H2BE19. Although redundancy between H2BE18 and H2BE19 ADP-ribosylation is also apparent following DSBs in vivo, by generating a strain with mutations at E18/E19 in the h2b locus we demonstrate these are the principal sites modified by Adprt1a/Adprt2. This identifies DNA damage induced histone mono-ADP-ribosylation sites by specific ARTs in vivo, providing a unique platform to assess how histone ADP-ribosylation regulates DNA repair.

Abstract
ADP-ribosylation by ADP-ribosyltransferases (ARTs) has a well-established role in DNA strand break repair by promoting enrichment of repair factors at damage sites through ADP-ribose interaction domains. Here, we exploit the simple eukaryote Dictyostelium to uncover a role for ADP-ribosylation in regulating DNA interstrand crosslink repair and redundancy of this pathway with non-homologous end-joining (NHEJ). In silico searches were used to identify a protein that contains a permutated macrodomain (which we call aprataxin/APLF-and-PNKP-like protein; APL). Structural analysis reveals that this permutated macrodomain retains features associated with ADP-ribose interactions and that APL is capable of binding poly(ADP-ribose) through this macrodomain. APL is enriched in chromatin in response to cisplatin treatment, an agent that induces DNA interstrand crosslinks (ICLs). This is dependent on the macrodomain of APL and the ART Adprt2, indicating a role for ADP-ribosylation in the cellular response to cisplatin. Although adprt2− cells are sensitive to cisplatin, ADP-ribosylation is evident in these cells owing to redundant signalling by the double-strand break (DSB)-responsive ART Adprt1a, promoting NHEJ-mediated repair. These data implicate ADP-ribosylation in DNA ICL repair and identify that NHEJ can function to resolve this form of DNA damage in the absence of Adprt2. Summary: Here, we identify a role for post-translational modification ADP-ribosylation in the response to DNA interstrand crosslinks in the model Dictyostelium.

Abstract
Poly (ADP-ribose) polymerase (PARP)-1 regulates various biological processes like DNA repair, cell death etc. However, the role of PARP-1 in growth and differentiation still remains elusive. The present study has been undertaken to understand the role of PARP-1 in growth and development of a unicellular eukaryote, Dictyostelium discoideum. In silico analysis demonstrates ADPRT1A as the ortholog of human PARP-1 in D. discoideum. The present study shows that ADPRT1A overexpression (A OE) led to slow growth of D. discoideum and significant population of AOE cells were in S and G2/M phase. Also, AOE cells exhibited high endogenous PARP activity, significant NAD(+) depletion and also significantly lower ADPRT1B and ADPRT2 transcript levels. Moreover, AOE cells are intrinsically stressed and also exhibited susceptibility to oxidative stress. AOE also affected development of D. discoideum predominantly streaming, aggregation and formation of early culminant which are concomitant with reports on PARP's role in D. discoideum development. In addition, under developmental stimuli, increased PARP activity was seen along with developmentally regulated transcript levels of ADPRT1A during D. discoideum multicellularity. Thus the present study suggests that PARP-1 regulates growth as well as the developmental morphogenesis of D. discoideum, thereby opening new avenues to understand the same in higher eukaryotes.

Abstract
Poly(ADP-ribose) polymerase-1 (PARP-1) is best characterised for its involvement in DNA repair. PARP-1 activity is also linked to cell fate, confounding its roles in maintaining genome integrity. The current study assessed the functional roles of PARP-1 within human lens cells in response to oxidative stress. The human lens epithelial cell line FHL124 and whole human lens cultures were used as experimental systems. Hydrogen peroxide (H2O2) was employed to induce oxidative stress and cell death was assessed by LDH release. The functional influence of PARP-1 was assessed using targeted siRNA and chemical inhibition (by AG14361). Immunocytochemistry and western blotting were used to assess PARP-1 expression and the alkaline comet assay determined the levels of DNA strand breaks. PARP-1 was generally observed in the cell nucleus in both the FHL124 cell line and whole human lenses. PARP-1 inhibition rendered FHL124 cells more susceptible to H2O2-induced DNA strand breaks. Interestingly, reduction of PARP-1 activity significantly inhibited H2O2-induced cell death relative to control cells. Inhibition of PARP-1 in whole human lenses resulted in a reduced level of lens opacity and cell death following exposure to H2O2 relative to matched pair controls. Thus, we show that PARP-1 could play a role in the fate of human lens cells, and these first observations in human lenses suggest that it could impact on lens opacity. Further studies are required to elucidate the regulatory processes that give rise to these effects. PARP-1 is found in the FHL124 lens cell line and whole human lens. PARP-1 inhibition increases H2O2-induced DNA strand breaks in human lens cells. Suppression of PARP-1 counters H2O2-induced human lens cell death. Inhibition of PARP-1 reduces H2O2-induced human lens opacity. PARP-1 could play a role in the fate of human lens cells and lens opacity.
