Moss secreted peptidome - Salicylic acid influences the protease activity and posttranslation modifications of the secreted peptides in the moss Physcomitrella patens

ABSTRACT: Plant secretome comprise dozens of secreted proteins and peptide hormones. However, little is known about peptide composition of plant secretome as well as proteases responsible for peptide pools generation. While the majority of studies focuses on the target detection and characterization of specific plant peptide hormones, we performed a comprehensive analysis of the whole extracellular peptidome, using moss Physcomitrella patens as a model object. We identified hundreds of modified and unmodified endogenous peptides originated from functional and non-functional protein precursors. Plant proteases responsible for shaping the pool of endogenous peptides were predicted. We showed that salicylic acid (SA) induces peptide production in the secretome.

Project description:Multigene families encoding diverse secreted peptide hormones play important roles in plant development. A need exists to efficiently elucidate the structures and post-translational-modifications of these difficult-to-isolate peptide hormones in planta so that their biological functions can be determined. A mass spectrometry and bioinformatics approach was developed to comprehensively analyse the secreted peptidome of Medicago hairy root cultures and xylem sap. We identified 759 spectra corresponding to the secreted products of twelve peptide hormones including four CEP (C-TERMINALLY ENCODED PEPTIDE), two CLE (CLV3/ENDOSPERM SURROUNDING REGION RELATED) and six XAP (XYLEM SAP ASSOCIATED PEPTIDE) peptides. The MtCEP1, MtCEP2, MtCEP5 and MtCEP8 peptides identified differed in post-translational-modifications. Most were hydroxylated at conserved proline residues but some MtCEP1 derivatives were tri-arabinosylated. In addition, many CEP peptides possessed unexpected N- and C-terminal extensions. The pattern of these extensions suggested roles for endo- and exoproteases in CEP peptide maturation. Longer -than -expected, hydroxylated and homogeneously modified mono- and tri-arabinosylated CEP peptides corresponding to their in vivo structures were chemically synthesised to probe the effect of these post-translational-modifications on function. The ability of CEP peptides to elevate root nodule number was increased by hydroxylation at key positions. MtCEP1 peptides with N-terminal extensions or with tri-arabinosylation modification, however, were unable to impart increased nodulation. The MtCLE5 and MtCLE17 peptides identified were of precise size, and inhibited main root growth and increased lateral root number. Six XAP peptides, each beginning with a conserved DY sulfation motif, were identified including MtXAP1a, MtXAP1b, MtXAP1c, MtXAP3, MtXAP5 and MtXAP7. MtXAP1a and MtXAP5 inhibited lateral root emergence. Transcriptional analyses demonstrated peptide hormone gene expression in the root vasculature and tip. Since hairy roots can be induced on many plants, their corresponding root cultures may represent ideal source materials to efficiently identify diverse peptide hormones in vivo in a broad range of species.

Project description:Senescent cells secrete a plethora of factors with potent paracrine signaling capacity. Strikingly, senescence, which acts as a defense against cell transformation, exerts pro-tumorigenic activities through its secretome by promoting numerous tumor-specific features, such as cellular proliferation, epithelial-mesenchymal transition and invasiveness. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has the unique activity of activating cell death exclusively in tumor cells. Given that the senescence-associated secretome supports cell transformation, we asked whether factor(s) of this secretome would establish a program required for the acquisition of TRAIL sensitivity. We found that conditioned media from several types of senescent cells (CMS) efficiently sensitized pre-transformed cells to TRAIL, while the same was not observed with normal or immortalized cells. Dynamic transcription profiling analysis of CMS-exposed pre-transformed cells revealed paracrine autoregulatory loop of senescence-associated secretome factors and a dominant role of CMS-induced MYC. Sensitization to TRAIL coincided with MYC upregulation and massive changes in gene regulation. CMS-induced MYC silenced its target gene CFLAR, encoding the apoptosis inhibitor FLIPL, thus leading to the acquisition of TRAIL sensitivity. Altogether, our results reveal that senescent cell-secreted factors exert a TRAIL sensitizing effect on pre-transformed cells by modulating the expression of MYC and CFLAR. Notably, CMS dose-dependent sensitization to TRAIL was observed with TRAIL-insensitive cancer cells and confirmed in co-culture experiments. Dissection and characterization of TRAIL-sensitizing CMS factors and the associated signaling pathway(s) may provide a mechanistic insight in the acquisition of TRAIL sensitivity and lead to novel concepts for the apoptogenic therapy of pre-malignant and TRAIL-resistant tumors. Pre-transformed BJEL cells were incubated with CMS for 0, 1, 3, 6, 8, 16 or 24 h respectively. Total RNA has been extracted from each time point and used for gene expression analysis (Affymetrix Human Gene 1.0 ST Arrays).

Project description:Analyzing culture supernatants of yeast and hyphal cells of Candida albicans by mass spectrometry, we found two close homologues of pathogenesis-related (PR-) 1 proteins, Rbe1p and Rbt4p, in the secretome of this human pathogen. By sequence homology, we assigned three yet not characterized open reading frames, ORF19.6200, ORF19.2787 and ORF19.2336, in addition to Rbe1p and Rbt4p to a novel family of proteins. Correspondent with our secretome analysis RBE1 was expressed in blastospores and opaque cells, whereas transcription was down-regulated in hyphae. On the contrary, RBT4 was up-regulated in hyphae and down-regulated in opaque cells. Remarkably, transcription of RBT4 and RBE1 was each up-regulated in blastospores of M-bM-^HM-^Frbe1 or hyphae of M-bM-^HM-^Frbt4 deletion strains, respectively, indicating a compensatory function of both proteins. In a M-bM-^HM-^Frbe1/M-bM-^HM-^Frbt4 double deletion strain, genome-wide transcriptional analysis showed differential transcription of a limited set of genes that are also implicated in virulence and oxidative stress response. In this context, deletion of RBE1 or RBT4 in a clinical C. albicans isolate resulted in a moderate but significant attenuation in virulence in a mouse model for disseminated candidiasis. However, a synergistic effect was observed in the M-bM-^HM-^Frbe1/M-bM-^HM-^Frbt4 double deletion strain, where virulence was strongly affected. Furthermore, the double deletion strain showed increased sensitivity to attack by polymorphonuclear leukocytes (neutrophils). Therfore, our data suggest that the crucial contribution of both C. albicans pathogenesis-related proteins for in vivo virulence results at least partially from reduced survival in phagocytes. Experiments were performed under blastospore (YPD) as well as hyphae (alpha-MEM)-inducing conditions. In total, three biological replicates were performed for each condition. All experiments were performed as dye swaps. Thus, in total six arrays have been hybridzed for each comparison (alpha-MEM and YPD, respectively). Hybridization experiments included a reference strain (C. albicans SC5314) and a double deletion strain (C. albicans MRC27). The array included one technical replicate of each probe.
