[PMID: 34062238 DOI: 10.1016/j.pep.2021.105923] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 05/06/2021] [Accepted: 05/25/2021] [Indexed: 01/17/2023]
Abstract
Poly (ADP-ribose) polymerase-1 (PARP-1) is a multifunctional protein that is associated with various biological processes like chromatin remodeling, DNA damage, cell death etc. In Dictyostelium discoideum, PARP-1 has also been implicated in cellular differentiation and development. However, its interacting proteins during multicellular development are not yet explored. Hence, the present study aims to identify PARP-1 interacting proteins during multicellular development of D. discoideum. BRCA1 C-terminus (BRCT) domain of PARP-1, which is mainly involved in protein-protein interactions was cloned in pGEX4T1 vector and developmental interactome of PARP-1 were analyzed by affinity purification-mass spectrometry. These interactions were further confirmed by in-silico protein-protein docking analysis, which led to identification of the proteins that show high affinity for BRCT domain. Initially, the protein structures were modeled on SWISS MODEL and PHYRE2 servers, refined by 3Drefine and validated by PROCHECK. Further, interaction sites of BRCT and the conserved regions in all interacting proteins were predicted using cons-PPISP and ConSurf, respectively. Finally, protein-protein docking analysis was done by HADDOCK. Our results identified 19 possible BRCT interacting proteins during D. discoideum development. Furthermore, interacting residues involved in the interactions and functional regions were explored. This is the first report where PARP-1's developmental interactome in D. discoideum is well established. The current findings demonstrate PARP-1's developmental interactome in D. discoideum and provide the groundwork to understand its regulated functions in developmental biology which would undoubtedly extend our perception towards developmental diseases in higher complex organisms and their treatment.

Abstract
BACKGROUND INFORMATION Poly(ADP-ribose) Polymerase-1 (PARP-1) is predominantly a nuclear protein and involved in various cellular processes like DNA repair, cell death, development, chromatin modulation etc. PARP-1 utilizes NAD+ and adds negatively charged PAR moieties on the target proteins. Over-activation of PARP-1 has been shown to cause energy crisis mediated cell death in which mitochondrial homeostasis is also affected. Moreover, the presence of mitochondrial NAD+ pools highlights the role of PARP-1 in mitochondria. The aim of present study is to understand the physiological role of PARP-1 in regulating mitochondrial functioning by varying the levels of PARP-1 in Dictyostelium discoideum. Intra-mitochondrial PARylation was analyzed by indirect immunofluorescence. Further, the effect of altered levels of PARP-1 i.e. overexpression, downregulation, knockout and its chemical inhibition was studied on mitochondrial respiration, reactive oxygen species (ROS) levels, ATP production, mitochondrial fission-fusion, mitochondrial morphology and mitochondrial DNA (mtDNA) content of D. discoideum. RESULTS Our results show intra-mitochondrial PARylation under oxidative stress. Altered levels of PARP-1 caused impairment in the mitochondrial respiratory capacity, leading to elevated ROS levels and reduced ATP production. Moreover, PARP-1 affects the mitochondrial morphology and mtDNA content, alters the mitochondrial fission-fusion processes in lieu of preventing cell death under physiological conditions. CONCLUSION The current study highlights the physiological role of PARP-1 in mitochondrial respiration, its morphology, fission-fusion processes and mtDNA maintenance in D. discoideum. SIGNIFICANCE This study would provide new clues on the PARP-1's crucial role in mitochondrial homeostasis, exploring the therapeutic potential of PARP-1 in various mitochondrial diseases.

Abstract
BACKGROUND Nuclear poly(ADP-ribose) polymerase-1 (PARP-1) is a well characterised protein that accounts for the majority of PARylation reactions using NAD+ as a substrate, regulating diverse cellular functions. In addition to its nuclear functions, several recent studies have identified localization of PARP-1 in mitochondria and emphasized its possible role in maintaining mitochondrial homeostasis. Various reports suggest that nuclear PARP-1 has been implicated in diverse mitochondria-specific communication processes. SCOPE OF REVIEW The present review emphasizes on the potential role of PARP-1 in mitochondrial processes such as bioenergetics, mtDNA maintenance, cell death and mitophagy. MAJOR CONCLUSIONS The origin of mitochondrial PARP-1 is still an enigma; however researchers are trying to establish the cross-talk between nuclear and mitochondrial PARP-1 and how these PARP-1 pools modulate mitochondrial activity. GENERAL SIGNIFICANCE A better understanding of the possible role of PARP-1 in mitochondrial homeostasis helps us to explore the potential therapeutic targets to protect mitochondrial dysfunctions.

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
Gene regulation mediates the processes of cellular development and differentiation leading to the origin of different cell types each having their own signature gene expression profile. However, the compact chromatin structure and the timely recruitment of molecules involved in various signaling pathways are of prime importance for temporal and spatial gene regulation that eventually contribute towards cell type and specificity. Poly (ADP-ribose) polymerase-1 (PARP-1), a 116-kDa nuclear multitasking protein is involved in modulation of chromatin condensation leading to altered gene expression. In response to activation signals, it adds ADP-ribose units to various target proteins including itself, thus regulating various key cellular processes like DNA repair, cell death, transcription, mRNA splicing etc. This review provides insights into the role of PARP-1 in gene regulation, cell differentiation and multicellular morphogenesis. In addition, the review also explores involvement of PARP-1 in immune cells development and therapeutic possibilities to treat various human diseases.

Abstract
PARP family members can be found spread across all domains and continue to be essential molecules from lower to higher eukaryotes. Poly (ADP-ribose) polymerase 1 (PARP-1), newly termed ADP-ribosyltransferase D-type 1 (ARTD1), is a ubiquitously expressed ADP-ribosyltransferase (ART) enzyme involved in key cellular processes such as DNA repair and cell death. This review assesses current developments in PARP-1 biology and activation signals for PARP-1, other than conventional DNA damage activation. Moreover, many essential functions of PARP-1 still remain elusive. PARP-1 is found to be involved in a myriad of cellular events via conservation of genomic integrity, chromatin dynamics and transcriptional regulation. This article briefly focuses on its other equally important overlooked functions during growth, metabolic regulation, spermatogenesis, embryogenesis, epigenetics and differentiation. Understanding the role of PARP-1, its multidimensional regulatory mechanisms in the cell and its dysregulation resulting in diseased states, will help in harnessing its true therapeutic potential.
