このレポートでは、軸索ローカライズATF4 mRNAの検出で高解像度のISH技術の使用を記載しています。これらおよび以前発表された研究は、この技術は、組織中の抗体ベースのタンパク質検出、あるいは胚全体33と互換性があることを示しています。重要なことは、最近34海馬ニューロンの樹状突起内のアークのmRNAの検出のために使用されてきました。また、組織染?...

軸索のmRNAの募集とローカル翻訳は、時間的および空間的に急性様式1に細胞外刺激に応答する軸索を可能にします。イントラ軸索タンパク質合成は、最良の軸索は、9-11を経路探索し、逆行12,13シグナリング 、それは成長円錐の動作2-8において重要な役割を果たしている神経発達の文脈で理解されています。軸索のmRNAとリボソームのレベルが大幅に14,15に減少している場合にははるかに少ないが、ポスト発達神経細胞における軸索タンパク質合成の機能的意義について知られています。成熟した脊椎動物の軸索は、長い16翻訳不活性であると考えられてきました。しかし、最近の研究では、地元の翻訳は、病理学的条件の下で成熟した軸索に再活性化されることを示しています。例えば、mRNAのサブセットは、神経損傷およびイントラ軸索タンパク質合成は、これらの軸索17の正確な再生のために必要とされる以下の再生軸索に補充されます。さらに、当社グループヘクタールSは、特定のmRNAがアルツハイマー病ペプチドAβ1-42へのローカルの暴露後に軸索に動員されることを実証し、転写因子ATF4のローカル翻訳は軸索のニューロンの細胞体18へのAβ1-42の神経変性作用を伝播するために必要です。最後に、ハイスループット分析は、成熟した軸索は、特に病理学的条件下で、18-21予想以上に複雑で動的なトランスクリプトームを持っていることを明らかにしました。これらの研究に照らして、成体の神経系において軸索局在化するmRNAを検出するための高感度かつ特異的な方法が必要とされています。 成熟した軸索におけるmRNA動員およびローカル翻訳の作業の多くは培養ニューロンに行われています。特殊な培養方法はsomato樹状区画18-20からの軸索の単離を可能にする存在するため、トランスクリプトーム解析のために、これは特にそうです。このような研究は、貴重なインを与えているが、成熟した軸索の現地翻訳の役割にIGHTは、培養神経細胞を忠実に生体内でまたはmRNAの募集は、培養条件への軸索の適応応答である場合は、状況を表しているかどうかの質問はまだ開いています。いくつかの研究は、in vivoで軸索を成熟mRNAの動員の証拠を提供しました。例えば、嗅覚マーカータンパク質をコードする転写物は、成人の感覚ニューロンにおける軸索22で検出されています。 βアクチンのmRNAの3 &#39;UTRを含む導入遺伝子は、マウスにおいて、末梢および中枢神経系ニューロンにおける軸索に輸送され、局所的に発達期間23の後に翻訳されます。ラミンB2 mRNAはXenopuesにおける網膜軸索に局在しているオタマジャクシをアフリカツメガエル、その枯渇は軸索の開発21た後、軸索の維持に影響を与えます。チトクロームCオキシダーゼIVをコードするmRNAの軸索輸送との干渉は、マウスの動作24を変化させます。最後に、ATF4 mRNAが成人aで発見されましたAβ1-42との関連で、マウスとヒトの脳のxonsは、神経変性18を誘発しました。 ハイスループットのトランスクリプトーム分析は、 インビトロで 、単離された軸索中のmRNAプロファイルを同定するために有用であることが証明さが、全体の組織の軸索における以降のインビボ研究は単独で見つからないが、神経細胞体、グリア細胞および他の細胞型と混在んために限界があるています。したがって、このような分析は、mRNAの細胞内局在を確認する画像技術と組み合わせされなければなりません。 in situハイブリダイゼーション （RNA ISH） における RNAは、細胞および組織中の特定のRNA配列の検出および視覚化を可能にします。ただし、元のRNA ISHアッセイは、まれにしか軸索ローカライズされたmRNAのためのケースではありません非常に豊富RNAを25の同定に適していました。努力を増加させる最後の数十年のために、単一分子レベルでのmRNAの検出を可能にする新たな技術の開発に置かれています<suP&gt; 25,26。例えば、歌手らは5蛍光非重複50マーを（詳細は27を参照）、標識されたことからなる、単一細胞でのmRNAを検出するためのISHプローブを開発しました。上記の技術と、ここで説明したものとの主な違いは、後者は20ダブルZ-構造（ないリニア）は、典型的には、関心を保証する特異性と低いバックグラウンドレベルのRNAの約1 kbの領域を標的プローブを使用していることです。プローブは、最終的に蛍光標識または発色反応を可能にする酵素と結合しているプリアンプやアンプの配列とハイブリダイズさせます。これらの増幅ステップは、他のISH技術28に比べて、信号対雑音比を改善します。ここでは、蛍光免疫細胞化学または軸索対比を可能にする組織学的染料のいずれかを組み合わせRNAscopeを使用して2つのプロトコルを記述します。両方のプロトコルは、大人のMOにATF4 mRNAの軸索の局在を可視化するのに適しています使用して、人間の脳。

detection of axonally localized mrnas in brain sections using high-resolution in situ hybridization

mRNAはしばしば、脊椎動物軸索に局在していると、地元の翻訳は、軸索の経路探索やpostdevelopmental期間中、開発中の分岐やメンテナンスのため、修理または神経変性のために必要とされます。ハイスループット分析は最近、軸索は、以前に予想以上にダイナミックで複雑なトランスクリプトームを持っていることを明らかにしました。これらの分析は、しかし、主に軸索はsomato樹状コンパートメントから単離することができる培養神経細胞で行われてきました。これは、in vivoでの組織全体でそのような分離を達成することは事実上不可能です。したがって、mRNAの採用や、動物全体におけるそれらの機能的関連性を検証するために、トランスクリプトーム解析は、理想的には、 その場でのmRNAの可視化を可能にする技術と組み合わせる必要があります。最近では、単一分子レベルでのRNAを検出する新規なISH技術が開発されています。 mRNAの細胞内局在を分析する際に特に重要です、ローカライズされたRNAは、典型的には、低レベルで見出されているからです。ここでは、新規の超RNA ISH技術を使用して、軸索に局在するmRNAの検出のための2つのプロトコルを記述します。我々は、成熟したマウスとヒトの脳におけるin vivoでの軸索にATF4 mRNAの募集を検証するために、蛍光免疫組織化学または組織学的染料を使用して軸索対比でRNAscope ISHを組み合わせています。

上記の手順の概要は図1に示されています。 ATF4 mRNAの最適な検出は、熱誘導アンマスキングを使用して、コリン作動性軸索に顆粒 mRNAの軸索の局在を評価する際には、軸索を識別することができるように、低豊富なRNAを可視化できることが重要です。ここで説明するRNA ISH技術は、単一分子分解能でのRNAの検出を可能に?...

Double Fluorescence in situ Hybridization in Fresh Brain Sections

Here we describe a modified version of a double fluorescence in situ hybridization (dFISH) method optimized for detecting two mRNAs of interest in fresh frozen brain sections. Our group has successfully used this approach to study gene co-regulation. More specifically, we have used this dFISH method to explore the anatomical organization, neurochemical properties, and the impact of sensory experience in central sensory circuits, at single cell resolution. This protocol has been validated in brain tissue from mice, rats and songbirds but is expected to be easily adaptable to other vertebrate species, as well as to an array of non-neural tissues. In this film we provide a detailed demonstration of the main steps of this procedure.

Quantitative Analysis of Alternative Pre-mRNA Splicing in Mouse Brain Sections Using RNA In Situ Hybridization Assay

Alternative splicing (AS) occurs in more than 90% of human genes. The expression pattern of an alternatively spliced exon is often regulated in a cell type-specific fashion. AS expression patterns are typically analyzed by RT-PCR and RNA-seq using RNA samples isolated from a population of cells. In situ examination of AS expression patterns for a particular biological structure can be carried out by RNA in situ hybridization (ISH) using exon-specific probes. However, this particular use of ISH has been limited because alternative exons are generally too short to design exon-specific probes. In this report, the use of BaseScope, a recently developed technology that employs short antisense oligonucleotides in RNA ISH, is described to analyze AS expression patterns in mouse brain sections. Exon 23a of neurofibromatosis type 1 (Nf1) is used as an example to illustrate that short exon-exon junction probes exhibit robust hybridization signals with high specificity in RNA ISH analysis on mouse brain sections. More importantly, signals detected with exon inclusion- and skipping-specific probes can be used to reliably calculate the percent spliced in values of Nf1 exon 23a expression in different anatomical areas of a mouse brain. The experimental protocol and calculation method for AS analysis are presented. The results indicate that BaseScope provides a powerful new tool to assess AS expression patterns in situ.

Rapid In Situ Hybridization using Oligonucleotide Probes on Paraformaldehyde-prefixed Brain of Rats with Serotonin Syndrome

3,4-Methylenedioxymethamphetamine (MDMA; ecstasy) toxicity may cause region-specific changes in serotonergic mRNA expression due to acute serotonin (5-hydroxytryptamine; 5-HT) syndrome. This hypothesis can be tested using in situ hybridization to detect the serotonin 5-HT2A receptor gene htr2a. In the past, such procedures, utilizing radioactive riboprobe, were difficult because of the complicated workflow that needs several days to perform and the added difficulty that the technique required the use of fresh frozen tissues maintained in an RNase-free environment. Recently, the development of short oligonucleotide probes has simplified in situ hybridization procedures and allowed the use of paraformaldehyde-prefixed brain sections, which are more widely available in laboratories. Here, we describe a detailed protocol using non-radioactive oligonucleotide probes on the prefixed brain tissues. Hybridization probes used for this study include dapB (a bacterial gene coding for dihydrodipicolinate reductase), ppiB (a housekeeping gene coding for peptidylprolyl isomerase B), and htr2a (a serotonin gene coding for 5-HT2A receptors). This method is relatively simply, cheap, reproducible and requires less than two days to complete.

Combining Double Fluorescence In Situ Hybridization with Immunolabelling for Detection of the Expression of Three Genes in Mouse Brain Sections

Detection of gene expression in different types of brain cells e.g., neurons, astrocytes, oligodendrocytes, oligodendrocyte precursors and microglia, can be hampered by the lack of specific primary or secondary antibodies for immunostaining. Here we describe a protocol to detect the expression of three different genes in the same brain section using double fluorescence in situ hybridization with two gene-specific probes followed by immunostaining with an antibody of high specificity directed against the protein encoded by a third gene. The Aspartoacyclase (ASPA) gene, mutations of which can lead to a rare human white matter disease - Canavan disease - is thought to be expressed in oligodendrocytes and microglia but not in astrocytes and neurons. However, the precise expression pattern of ASPA in the brain has yet to be established. This protocol has allowed us to determine that ASPA is expressed in a subset of mature oligodendrocytes and it can be generally applied to a wide range of gene expression pattern studies.

In Situ Hybridization for the Precise Localization of Transcripts in Plants

With the advances in genomics research of the past decade, plant biology has seen numerous studies presenting large-scale quantitative analyses of gene expression. Microarray and next generation sequencing approaches are being used to investigate developmental, physiological and stress response processes, dissect epigenetic and small RNA pathways, and build large gene regulatory networks1-3. While these techniques facilitate the simultaneous analysis of large gene sets, they typically provide a very limited spatiotemporal resolution of gene expression changes. This limitation can be partially overcome by using either profiling method in conjunction with lasermicrodissection or fluorescence-activated cell sorting4-7. However, to fully understand the biological role of a gene, knowledge of its spatiotemporal pattern of expression at a cellular resolution is essential. Particularly, when studying development or the effects of environmental stimuli and mutants can the detailed analysis of a gene's expression pattern become essential. For instance, subtle quantitative differences in the expression levels of key regulatory genes can lead to dramatic phenotypes when associated with the loss or gain of expression in specific cell types. 
Several methods are routinely used for the detailed examination of gene expression patterns. One is through analysis of transgenic reporter lines. Such analysis can, however, become time-consuming when analyzing multiple genes or working in plants recalcitrant to transformation. Moreover, an independent validation to ensure that the transgene expression pattern mimics that of the endogenous gene is typically required. Immunohistochemical protein localization or mRNA in situ hybridization present relatively fast alternatives for the direct visualization of gene expression within cells and tissues. The latter has the distinct advantage that it can be readily used on any gene of interest. In situ hybridization allows detection of target mRNAs in cells by hybridization with a labeled anti-sense RNA probe obtained by in vitro transcription of the gene of interest. 
Here we outline a protocol for the in situ localization of gene expression in plants that is highly sensitivity and specific. It is optimized for use with paraformaldehyde fixed, paraffin-embedded sections, which give excellent preservation of histology, and DIG-labeled probes that are visualized by immuno-detection and alkaline-phosphatase colorimetric reaction. This protocol has been successfully applied to a number of tissues from a wide range of plant species, and can be used to analyze expression of mRNAs as well as small RNAs8-14.

Radioactive in situ Hybridization for Detecting Diverse Gene Expression Patterns in Tissue

Knowing the timing, level, cellular localization, and cell type that a gene is expressed in contributes to our understanding of the function of the gene. Each of these features can be accomplished with in situ hybridization to mRNAs within cells. Here we present a radioactive in situ hybridization method modified from Clayton et al. (1988)1 that has been working successfully in our lab for many years, especially for adult vertebrate brains2-5. The long complementary RNA (cRNA) probes to the target sequence allows for detection of low abundance transcripts6,7. Incorporation of radioactive nucleotides into the cRNA probes allows for further detection sensitivity of low abundance transcripts and quantitative analyses, either by light sensitive x-ray film or emulsion coated over the tissue. These detection methods provide a long-term record of target gene expression. Compared with non-radioactive probe methods, such as DIG-labeling, the radioactive probe hybridization method does not require multiple amplification steps using HRP-antibodies and/or TSA kit to detect low abundance transcripts. Therefore, this method provides a linear relation between signal intensity and targeted mRNA amounts for quantitative analysis. It allows processing 100-200 slides simultaneously. It works well for different developmental stages of embryos. Most developmental studies of gene expression use whole embryos and non-radioactive approaches8,9, in part because embryonic tissue is more fragile than adult tissue, with less cohesion between cells, making it difficult to see boundaries between cell populations with tissue sections. In contrast, our radioactive approach, due to the larger range of sensitivity, is able to obtain higher contrast in resolution of gene expression between tissue regions, making it easier to see boundaries between populations. Using this method, researchers could reveal the possible significance of a newly identified gene, and further predict the function of the gene of interest.

Radioactive in situ Hybridization for Detecting Diverse Gene Expression Patterns in Tissue

This protocol is successfully used to quantitatively detect levels and spatial patterns of mRNA expression in multiple tissue types across vertebrate species. The method can detect low abundance transcripts and allows processing of hundreds of slides simultaneously. We present this protocol using expression profiling of avian embryonic brain formation as an example.

Combining Multiplex Fluorescence In Situ Hybridization with Fluorescent Immunohistochemistry on Fresh Frozen or Fixed Mouse Brain Sections

Fluorescent in situ hybridization (FISH) is a molecular technique that identifies the presence and spatial distribution of specific RNA transcripts within cells. Neurochemical phenotyping of functionally identified neurons usually requires concurrent labelling with multiple antibodies (targeting protein) using immunohistochemistry (IHC) and optimization of in situ hybridization (targeting RNA), in tandem. A &#34;neurochemical signature&#34; to characterize particular neurons may be achieved however complicating factors include the need to verify FISH and IHC targets before combining the methods, and the limited number of RNAs and proteins that may be targeted simultaneously within the same tissue section.
Here we describe a protocol, using both fresh frozen and fixed mouse brain preparations, which detects multiple mRNAs and proteins in the same brain section using RNAscope FISH followed by fluorescence immunostaining, respectively. We use the combined method to describe the expression pattern of low abundance mRNAs (e.g., galanin receptor 1) and high abundance mRNAs (e.g., glycine transporter 2), in immunohistochemically identified brainstem nuclei.
Key considerations for protein labelling downstream of the FISH assay extend beyond tissue preparation and optimization of FISH probe labelling. For example, we found that antibody binding and labelling specificity can be detrimentally affected by the protease step within the FISH probe assay. Proteases catalyze hydrolytic cleavage of peptide bonds, facilitating FISH probe entry into cells, however they may also digest the protein targeted by the subsequent IHC assay, producing off target binding. The subcellular location of the targeted protein is another factor contributing to IHC success following FISH probe assay. We observed IHC specificity to be retained when the targeted protein is membrane bound, whereas IHC targeting cytoplasmic protein required extensive troubleshooting. Finally, we found handling of slide-mounted fixed frozen tissue more challenging than fresh frozen tissue, however IHC quality was overall better with fixed frozen tissue, when combined with RNAscope.
