This study by Sidhu et al. USA 110, 543548 (2013). Replication protein A (RPA) is the major protein that binds to single-stranded DNA (ssDNA) in eukaryotic cells. Blake, J. The chaperone BiP can bind to misfolded proteins to be degraded through the proteasome, PDI is an abundant oxidoreductase present in eukaryotic ER and catalyzes the folding of proteins, whereas HSPs facilitates both correct folding and degradation [40]. Starting in mid-prophase I, a tripartite structure call synaptonemal complex forms between two homologous chromosome axes which is also important for meiotic recombination [6]. Bioinformatics. CD63 and CD63high round spermatids (1N) were isolated according to Hoechst 33342 staining and APC fluorescent label using FACS. Schmid, R. et al. The answer is recombination, a process that shuffles the allele content between homologous chromosomes during cell division. Perhaps CML228 maize, naturally adapted to crossover-inhibiting heat stress, displays fewer COs when grown in a controlled environment, which could be a different story when all lines are grown under heat stress. Percent of aligned reads for the B73, Mo17, and CML228 meiocytes to B73 v5 reference, Mo17 v1 reference, and CML228 v1 reference. Additionally, genes involved in microtubule structure and cell plate such as Precocious dissociation of sisters-like 5 (Pds5) and protein TPX2 were down-regulated in CML228 (Supplementary Table 4). Significantly differentially expressed genes in "cell cycle" gene ontology category: their expression levels (shown in Z-scores) and functions. During pachytene, both oocytes and spermatocytes differentially regulate the stability of SYP-2 and SYP-3 within an assembled SC, with increased SYP-2 dynamics in spermatocytes and increased SYP-3 dynamics in oocytes. c Schematic overview of intracytoplasmic round spermatid injection (ROSI) with steps 12 (RS1o2), and steps 78 (RS7o8) spermatids. Earlier studies have observed AS changes around meiosis.6,16,17 However, these studies did not address global splicing and splicing regulator changes during spermatogenesis, especially at the mitotic-to-meiotic transition. Of these TFs, Crem, and Rfx2 have been previously shown to be critical for spermiogenesis,4,38 whereas several other putative TFs (such as Sox30 and Zfp541) might also function during spermiogenesis. One way continues replication of the heavy strand through a substantial part (e.g. PubMedGoogle Scholar. The splicing landscape is globally reprogrammed during male meiosis. https://doi.org/10.1186/s12870-021-03173-5. Annu Rev Plant Biol. A total of two libraries were created (one for each biological replicate) and sequenced with at least 40 million reads per library. Use the Previous and Next buttons to navigate three slides at a time, or the slide dot buttons at the end to jump three slides at a time. 5a). Provided by the Springer Nature SharedIt content-sharing initiative. Directionality, in molecular biology and biochemistry, is the end-to-end chemical orientation of a single strand of nucleic acid.In a single strand of DNA or RNA, the chemical convention of naming carbon atoms in the nucleotide pentose-sugar-ring means that there will be a 5 end (usually pronounced "five-prime end"), which frequently contains a phosphate group attached to the 5 Differential expression analysis was done in Galaxy [54]. Whole-mount immunostaining of seminiferous tubules for GFP (green) and LIN28 (red) (top panel) in Lin28-YFP mice. Biol. Of the significantly changed genes between early preleptotene and middle preleptotene (mid-preleptotene) spermatocytes, hundreds of upregulated genes were strongly enriched for meiosis-related terms, including most of the genes known to be associated with recombination, synapsis, and chromosome segregation (Supplementary information, TableS5). If GO enrichment tools can be improved to take in gene names of Mo17 and CML228 as inputs (currently the ShinyGO0.76.2 application we are using only takes in B73 gene names), those genes specific to each of the genomes should beinvestigated. We examined several well-characterized meiotic DNA damage repair genes and found that some of them were differentially expressed in CML228, B73 and Mo17 (Table 1), while other genes were non-differentially expressed (Supplementary Table 3). Bolger AM, Lohse M, Usadel B. Trimmomatic: a flexible trimmer for illumina sequence data. Wijeratne AJ, Chen C, Zhang W, Timofejeva L, Ma H. The Arabidopsis Thaliana PARTING DANCERS gene encoding a novel protein is required for normal meiotic homologous recombination. The key intermediate, AHBA, is a common precursor to other anticancer drugs, such as rifamycin and ansamycin.. In vitro, RPA shows a much higher affinity for ssDNA than RNA or double-stranded DNA. The single-cell RNA-seq data for a large number of postmeiotic cells here provided the opportunity to address this question. Trapnell, C., Pachter, L. & Salzberg, S. L. TopHat: discovering splice junctions with RNA-Seq. Curr Biol. Spike-in antibody (0.5g) and spike-in chromatin (5ng) were used in this ChIP assay according to the manufacturers guidelines. In Arabidopsis, such roles of Zyp1 was found [11]. 3); KEGG pathways associated with down-regulated genes in CML228 include ribosome, starch and sucrose metabolism, and circadian rhythm. We do not yet know how the three lines would perform under CML228s native tropical climate or the temperate climate. Thorvaldsdttir, H., Robinson, J. T. & Mesirov, J. P. Integrative Genomics Viewer (IGV): high-performance genomics data visualization and exploration. Bioinformatics. An effect of heat stress on the organization of microtubules has previously been observed in perennial ryegrass and sorghum [50]. Kim J-H. Chromatin remodeling and epigenetic regulation in plant DNA damage repair. Cell Cycle. J Exp Bot. Cell Biol. SOX30 antibody (5g) was incubated with chromatin samples overnight at 4C. Hufford MB, Seetharam AS, Woodhouse MR, Chougule KM, Shujun Ou, Liu J, Ricci WA, et al. 1a, b). We speculate that overall cell division related processes were inhibited in CML228 due to its adaptation to tropical stress, while this consequence was even more pronounced in the meiocytes. Dukowic-Schulze S, Sundararajan A, Mudge J, Ramaraj T, Farmer AD, Wang M, Sun Qi, et al. Ball, R. L. et al. 2014;26(7):296277. and F.T. S22c). In sexually reproducing organisms, germ cells faithfully transmit the genome to the next generation by forming haploid gametes, such as eggs and sperm. [26] Female and male MLH1(-/-) mutant mice are infertile, and sterility is associated with a reduced level of chiasmata. Removal of either the plant-encoded or nematode-encoded steps in the pathway greatly reduced parasitic success. Otherwise, we defined that gene as a MSCI TypeII Gene. ZYP1, which is compared to the teeth of the molecular zipper that is in the synaptonemal complex, plays a role both in ensuring one CO per pair of chromosomes (CO assurance) and in limiting closely spaced CO formation once that goal is reached [6, 11]. USA 113, E5408E5415 (2016). Among the genes that had reads per kilobase per million (RPKM) values greater than 2, a total of 14,206 genes were annotated in all three reference genomes (Supplementary Fig. Since there is a homolog 2 of Mus81 in maize, perhaps a double mutant for this gene also needs to be considered.

Homologous recombination New Phytol. The qPCR results showed that although not significant, the relative expression of Zyp1 was numerically higher in CML228 compared with B73 or Mo17 using ANOVA and Tukeys HSD test (Supplementary Fig. The related nucleotide excision repair pathway repairs bulky helix-distorting lesions. & Mchler, M. Scatterplot3d-an R package for visualizing multivariate data. Cyclin dependent protein kinases and stress responses in plants. 2006;10(6):80919. 73, 279319 (2010). 4d). Overall, we identified that 637 out of 817 (78.0%) X chromosome protein-coding genes, and 18 out of 40 (45.0%) Y chromosome protein-coding genes were expressed in spermatogenic cells (Supplementary information, TableS8; see Materials and Methods).
D-loop Genes that had a reads per kilobase million (RPKM) value greater than 2 of B73, Mo17, and CML228 meiocytes aligned to the B73 v5 reference genome. For up-regulated genes, we only considered the splicing event in the next stage; for down-regulated genes, we only considered the splicing event in the previous stage (Fig. The DNA/RNA-binding protein, TB-RBP, moves from the nucleus to the cytoplasm and through intercellular bridges in male germ cells.
4 Types of Chromosomal Aberrations Zhang, Y. et al. Single-cell RNA-seq expression data was transferred into log2(TPM/10+1). Some of our discussion was based on the assumption that the differences in the three maize inbreds were due to their adaptations to different climatic zones. Brief. The images or other third party material in this article are included in the articles Creative Commons license, unless indicated otherwise in a credit line to the material. Proc. Nucleic Acids Res. Deficient expression of multiple DNA repair genes are often found in cancers,[18] and may contribute to the thousands of mutations usually found in cancers (see Mutation frequencies in cancers). 2A). Our datasets allowed us to dissect the precise temporal regulation and the signature genes for each cluster and each cell stage, as detailed below. & Handel, M. A. Protamine transcript sharing among postmeiotic spermatids. Oocytes, injected with spermatids from steps 12 and steps 78, were cleaved into two-cell embryos with an equivalent efficiency after activation (93.2 vs. 94.7%; Fig. Could it be due to differences in adaptation to different environments? After strand invasion, the further sequence of events may follow either of two main pathways leading to a crossover (CO) or a non-crossover (NCO) recombinant (see Genetic recombination). Lightfoot J, Testori S, Barroso C, Martinez-Perez E. Loading of Meiotic Cohesin by SCC-2 is required for early processing of DSBs and for the DNA damage checkpoint. Stphanie Durand et al, Joint control of meiotic crossover patterning by the synaptonemal complex and HEI10 dosage, Nature Communications (2022). [12], When a double-stranded DNA molecule has suffered a break in both strands, one repair mechanism available in diploid eukaryotic cells is homologous recombination repair. 17, 294 (2016). See Materials and Methods for details. In this work, we developed a combinatorial method to purify all relevant types of mouse synchronous and homogenous spermatogenic cells. The oligo dT reverse transcription primer was composed of 8 nt sample-specific barcode, 8 nt unique molecular identifiers (UMIs) and 25 nt oligo dT primer (TCAGACGTGTGCTCTTCCGATCT-XXXXXXXX-NNNNNNNN-T25, X standing for barcode and N representing UMI). We then evaluated the efficacy of one candidate surface marker CD63 in distinguishing round spermatids at different stages, and found that the CD63 subset in haploid cells was highly enriched with steps 78 spermatids, whereas the CD63high population was enriched with steps 12 spermatids (Fig. Out of these, 3,664 genes showed a false discovery rate (FDR)<0.01 and a fold change greater than 2 among B73, Mo17 and CML228 (Supplementary Table 2). 2009;325(5941):73740. Taken together, we demonstrate dosage-dependent regulation of individual SC components with sex-specific functions in recombination. 2016;8(2):7578. [18] In one example, involving MLH1, Jiang et al. Fourteen babies born after round spermatid injection into human oocytes. Namekawa, S. H. et al. Scale bar, 50m. [3] found that nucleosome occupancy patterns at CO sites were different between the crosses B73 Mo17 and B73 CML228 in maize. https://doi.org/10.1073/pnas.0805596105. injection of 5-ethynyl-2-deoxyuridine (EdU; 50g/g body weight in PBS) 2h prior to euthanization. The types are: 1. https://doi.org/10.1093/bioinformatics/btp352. Google Scholar. In molecular biology, a displacement loop or D-loop is a DNA structure where the two strands of a double-stranded DNA molecule are separated for a stretch and held apart by a third strand of DNA. Sex, as well as meiotic recombination between homologous chromosomes, is nearly ubiquitous among eukaryotes. Get weekly and/or daily updates delivered to your inbox. In summary, we used natural maize inbred lines that were from different climatic conditions and have shown their differences in expression landscape in male meiocytes. California Privacy Statement, Single-cell RNA-seq uncovers dynamic processes and critical regulators in mouse spermatogenesis. We find that SC composition is regulated by sex-specific mechanisms throughout meiotic prophase I. Testes were fixed in Bouins buffer or 4% paraformaldehyde (PFA), embedded in paraffin and sectioned. Molecular Biology of the Cell is the classic in-depth text reference in cell biology. 88, 40 (2013). The finding that alignment of the transcriptomes to the same reference genome show similar expression patterns as alignment to their corresponding reference genome (Fig. Google Scholar. I am a PhD student working in Natasha Yelina's group on manipulating meiotic recombination for crop breeding with a focus on developing virus-induced gene silencing and editing in soybean. Plant Cell. Crop Sci. 1b), we were able to isolate individual As, Ap, and Aal spermatogonia in situ using the Unipick system. a Boxplots showing the numbers of protein-coding genes on sex chromosomes expressed in each individual cell at 20 developmental stages. The finding that we did not detect GO categories or KEGG pathways directly involved in DNA damage repair or meiosis suggests that the expression of these genes was mostly conserved across the three maize inbreds examined. Translocation 4. S24b). Ribosome elimination was said to play a role during meiosis which could be a mechanism to remove mRNAs and proteins before the gamete stage [38]. This reinforces the theory that the transcriptional program for mitotic-to-meiotic transition may be switched on at the preleptotene stage before meiotic prophase.
DNA mismatch repair As pointed out by Rubin, "The vast majority of studies in cancer research has been done on well-defined tumors in vivo, or on discrete neoplastic foci in vitro. EEJ exon-exon junction, IR intron retention, ALTD alternative donors, ALTA alternative acceptors. DNA demethylation dynamics in the human prenatal germline. Particularly, transport and energy related processes were up-regulated in CML228, while chromatin, nucleolus, RNA processing, and growth-related processes such as cell cycle were down-regulated in CML228. Mitomycin C is used as a medicine for treating various disorders associated with the growth and spread of cells. All statistics analysis were performed in R language. Mol. ATM serine/threonine kinase, symbol ATM, is a serine/threonine protein kinase that is recruited and activated by DNA double-strand breaks.It phosphorylates several key proteins that initiate activation of the DNA damage checkpoint, leading to cell cycle arrest, DNA repair or apoptosis.Several of these targets, including p53, CHK2, BRCA1, NBS1 and H2AX are tumor Then the protein-DNA complexes were immobilized to 30L protein A/G beads, followed by washing twice with lysis buffer, 3 times with low salt buffer (10mM Tris-HCl, 250mM LiCl, 1mM EDTA, 0.5% NP40, 0.5% Na-deoxylcholate and 1 protease inhibitor cocktail) and once with 10mM Tris-HCl, pH 8.0. It is known that under heat and drought stress, reproductive organs are more susceptible than the vegetative parts [42, 46,47,48]. While these observations might be related to the previously observed lower chiasmata number observed in CML228 [15], epigenetic modifications might also play a role. Osadchuk K, Cheng C-L, Irish EE. 6c).
The content is provided for information purposes only. We found that genes involved in DNA replication were highly enriched in cluster C2, including S phase preleptotene spermatocytes, where this process occurs (Fig. Nature 337, 373376 (1989). Analysis was done using the integrated BioRad CFX Manager software. Transcriptome analysis of highly purified mouse spermatogenic cell populations: gene expression signatures switch from meiotic-to postmeiotic-related processes at pachytene stage. Crossover numbers are also tightly regulated and generally do not exceed three. Langmead, B. Genetics. Microsc. Tsubouchi T, Zhao H, Shirleen Roeder G. The meiosis-specific Zip4 protein regulates crossover distribution by promoting synaptonemal complex formation together with Zip2. BMC Genomics Supplementary Table 6. 1991;83(1):2117. We found that 575 sex chromosome-linked protein-coding genes were expressed in spermatogenic cells at some stage before early pachynema.

Values shown for each sample were Z-scores, indicating levels of gene expression. Although most meiotic proteins are conserved between eggs and sperm, many aspects of meiosis are sexually dimorphic. The ability to isolate homogeneous spermatogenic cells allowed us to not only accurately decipher the involvement of molecules in cellular state transitions and stage-specific gene regulation, but also to utilize these cells for functional characterization. Selected DNA damage repair genes were differentially expressed among the tested inbred lines. This pair of genes is only expressed in developing lymphocytes while they are engaged in assembling their antigen receptors, as is described in more detail in Chapter 7. Focusing on this set of 14,206 genes did leave out a portion of genes that could be differentially expressed, but the majority (76%) of the genes were included as compared to the 18,503 genes when all three meiocyte transcriptomes were aligned to the same B73 v5 reference [43],Supplementary Fig. 3a and Supplementary information, Fig. S22a, b). New York, NY: Humana.
Nuclear-embedded mitochondrial DNA sequences in 66,083 Thus, these limitations of cell purity have been particularly a problem to decipher the molecular hallmarks defining the premeiotic and meiotic spermatocytes, and the round spermatid sub-stages, and to elucidate the molecular basis of the mitotic-to-meiotic switch and the meiotic-to-postmeiotic transition in mammals. At least one CO per chromosome pair is needed for proper chromosome segregation, whereas no more than four COs per pair chromosomes are commonly observed in most eukaryotes [1].

The major challenge remains isolating high-purity homogeneous spermatogenic cells of all subtypes from mouse testis. 3, a002626(2011).
MCB: Exam 2 Sapling Questions Differential gene and transcript expression analysis of RNA-seq experiments with TopHat and Cufflinks. Transport and energy-related processes was up-regulated and Cyclin13 was down-regulated in CML228. Nat Biotechnol. S1b, c).21 After spermatogenesis was synchronized, the spermatogenic cells in the testis included the undifferentiated spermatogonia that are labeled by both YFP and dTomato, and the synchronous advanced spermatogenic cells at specific stages (from type In spermatogonia onwards), which are only labeled by dTomato (Fig. 2009;326(5956):11125. Stra8-GFPCre mice were used for synchronous spermatogenesis to generate type A1 spermatogonia. The cell suspension was centrifuged and the pellet was resuspended at a concentration of 1106 cells/40L, followed by incubating with APC-conjugated anti-CD63 antibody (0.1g/106 cells) for 30min on ice and washed twice with DMEM. Values shown for each sample were Z-scores, indicating levels of gene expression. This suggests that IR change is a predominant feature of splicing regulation in male germ cell development (Fig. The MRN (MRE11, RAD50, NBS1) complex creates single-strand overhangs at the ends of the DSB, resulting in single-end invasion which is loaded by two bacterial recombinase RecA-like proteins, RAD51 and DMC1 [4,5,6,7]. M.-H.T. conducted the Fbxo47 experiments. The single cells were picked using the Unipick system according to fluorescence and cell size. 1). In the Table above, MLH1 deficiencies were noted in the field defects (histologically normal tissues) surrounding most of the cancers. Supplementary Figure 5. Moreover, we noticed that transcriptional profilings of type In spermatogonia closely resembled that of type B spermatogonia, whereas the transcriptome of type B spermatogonia was very similar to that of G1 phase preleptotene spermatocytes. Organize these steps in the order in which they would occur during cell division.
CliffsNotes Two Types of Meiotic Crossovers Coexist in Maize. The P value is calculated by two-tailed Students t-test. To test this hypothesis, we first performed intracytoplasmic round spermatid injection (ROSI) using FACS-enriched spermatids synchronized at different stages (Fig. 52, 198236 (1972). Google Scholar. two-thirds) of the circular molecule, and then replication of the light strand begins. (A) Heatmap showing sample-to-sample distance matrix. Cold Spring Harb. The continued presence of a clone with an epigenetically repressed MLH1 would continue to generate further mutations, some of which could produce a tumor. 2d, e). RPA is required in replication, recombination and repair processes such as nucleotide excision repair and homologous recombination. We established an approach to successfully purify all types of homogeneous male germ cells from mice at both single-cell resolution and population levels. Characterization of dynamic patterns of alternative splicing and its regulation during spermatogenesis. Color key from yellow to blue represents the relative gene expression level from high to low. Importantly, massively increasing crossovers in this way barely affected cell division. We only considered the alternative splicing genes that were subjected to at least 2 types of junctions (EEJ, IR, ALTD, or ALTA) in one given cell/sample. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Mouse spermatids ranging from round to elongated cells can be morphologically defined as steps 18 round spermatids, and steps 916 elongating spermatids.2. Of the 65 two-cell embryos, 48 developed to blastocysts at a rate of 73.8%, which is >6-fold higher compared with that of steps 12 spermatids (11.1%; Fig. A total of 51 genes were in the cell cycle GO category, 14 of which were also in the cyclin-dependent serine/threonine related kinases GO categories (Fig. Interphase is divided into three phases: Meiotic recombination is mediated through double stranded break, which is catalyzed by Spo11 protein. https://doi.org/10.1073/pnas.1713225114.

The Sequence Alignment/Map Format and SAMtools. 1). BMC Genom. After all, this study only examined the zygotene stage transcriptomes of these maize inbreds. During this process, Rad51 and Dmc1 recombinases bind the 3 single-strand DNA (ssDNA) tails to form helical Among 20 cancers evaluated, microsatellite instable colon cancer (mismatch repair deficient) had the second highest frequency of mutations (after melanoma). Complete synapsis and XY body formation are characteristics of pachytene nuclei. https://doi.org/10.1105/tpc.109.071514. 33, 495502 (2015). Dev. d Gene ontology (GO) analysis of down-regulated DEGs from clusters C2 to C3 (upper panel), down-regulated DEGs from C3 to C4 (middle panel) and up-regulated DEGs from C4 to C5 (bottom panel), respectively. Next, DHQ synthase catalyzes a ring closure to give 4-amino3-dehydroquinate (aminoDHQ), which then undergoes a double oxidation via aminoDHQ dehydratase to give 4-amino-dehydroshikimate (aminoDHS). and Z.L. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. DNA mismatch repair functions to correct replication errors in newly synthesized DNA and to prevent recombination between related, but not identical (homeologous), DNA sequences. We isolated twenty different subtypes of spermatogenic cells from spermatogenesis synchronous mice with Lin28-YFP and Vasa-dTomato alleles as described above. d GO analysis of escaped MSCI genes.
