TY - JOUR. T1 - Immunohistochemical distribution of pro-somatostatin-related peptides in cerebral cortex. AU - Morrison, John H.. AU - Benoit, Robert. AU - Magistretti, Pierre. AU - Bloom, Floyd E.. PY - 1983/3/7. Y1 - 1983/3/7. N2 - Mammalian brain contains 3 peptides related to the pro-somatostatin molecule: somatostatin-14 (SS14), the form originally identified from hypothalamic extracts, somatostatin 28 (SS28) and somatostaton 28 (1-12) (SS28 (1-12)). By using antibodies which selectively recognize one or more of these 3 somatostatin-related peptides, we have characterized their immunohistochemical distribution in neocortex. These somatostatin-related peptides have a specific laminar distribution in cortex and are differentially distributed such that SS28 is largely restricted to cell bodies, whereas SS28 (1-12) is preferentially localized in neuroal processes and terminals in a density which far exceeds that revealed by SS-14 immunoreactivity. These data suggest that there may be an ...

We evaluated the effectiveness of a combination of homogeneously selected criteria and immunohistochemical (IHC) characteristics of Familial Breast Cancers (FBCs) in detecting BRCA1 mutation carriers. Methods: Primary breast tumours from 93 FBC patients defined by specific eligibility criteria, based on personal and familial tumour history, were ...
Endometrial adenocarcinomas are a rare type of tumour in cats. Though different morphologies have been reported, the most frequent histological type of feline endometrial adenocarcinoma (FEA) is the papillary serous. Characterization of molecular markers expression in FEA may contribute to clarify the pathogenesis of these tumours and to assess the differences between normal endometrium and FEA regarding the expression pattern of several proteins. Therefore, this study aimed to evaluate the immunohistochemical profile of a wide panel of antibodies (specific for ER-α, PR, Ki-67, CK7 and CK20) in twenty-four cases of FEA. Comparisons were made between FEA and feline normal cyclic endometrium in follicular (n = 13) and luteal (n = 10) stages. Except for Ki-67, all other molecular markers were assessed independently for the intensity of immunolabeling and for the percentage of cells expressing the protein. This study showed that in FEA a loss of expression occurs for ER-α (P ≤ 0.0001) and less markedly
The altered expression patterns of glypican and syndecan-1 and -4 in chronic ulcers reflect their possible roles during inflammation and cell proliferation. Hence, analysis of PG expression should be of interest in future studies on normal as well as defective wound healing.
Single clustering methods have often been used to elucidate clusters in high dimensional medical data, even though reliance on a single algorithm is known to be problematic. In this paper, we present a methodology to determine a set of core classes by using a range of techniques to reach consensus across several different clustering algorithms, and to ascertain the key characteristics of these classes. We apply the methodology to immunohistochemical data from breast cancer patients. In doing so, we identify six core classes, of which several may be novel sub-groups not previously emphasised in literature.. ...
POSCC is a rare variant of SCC that is histologically similar to typical SCC but with the presence of non-neoplastic melanocytes within the lesion (20,22). Pigmentation in POSCC is not always macroscopically visible and may be detected only microscopically (18,19). Our study examined only the cases in which the pigmentation could be macroscopically observed in the primary sites. There was no data in the literature on the prevalence of POSCC. In this study, POSCC was prevalent in 1.7% of the total OSCC cases. To the best of our knowledge, this is the first study to evaluate the clinicopathological and biological features of POSCC.. The most common location of POSCC in this study was the tongue (72%), which is consistent with previous findings (13-22) and in line with conventional OSCC. Similar to 18 reported cases (13-22), 23 tumors (92%) were diagnosed as pathological T1-T2 stage. In total, 23 of 25 cases (92%) were low-invasive type POSCC. There were 3 of 25 patients (12%) who had pathological ...
Overview Pathologists frequently use immunohistochemistry (IHC) to evaluate antigen location and expression patterns in tissue for diagnostic and/or prognostic purposes. This process often also requires quantification of these immunostains to assist in therapeutic drug selection. Traditional scoring systems for IHC have relied on manual subjective interpretation and semiquantification of immunostains by pathologists examining microscopic glass…

The diagnosis of SPT is made based on the clinical presentation, location of tumor, histological findings, and immunohistochemical staining. SPTs express positive immunohistochemical staining for vimentin, CD56, alpha-1-antitrypsin and neuron-specific enolase. Epithelial markers (keratins) may be focal or weakly positive. Synaptophysin is commonly positive in SPTs; however, chromogranin is usually negative. Immunohistochemical staining for Amylase/Lipase/Trypsin are negative, as well as those for pancreatic hormones. There may be positive immunohistochemical staining for CD10, Beta- catenin, CD117 (c-kit), Progesterone receptor, and the beta form of estrogen receptor. SPTs are considered to be tumors of low malignant potential and more than 80% of SPTs are cured by surgical resection. However, metastases may be seen in a small percentage of patients. When metastasis occurs, it is usually to the liver or peritoneum. Patient follow-up: The patient underwent a brain biopsy. Histologic examination ...

41 colon cancer patients were tested for MMR status using immunohistochemistry between March 2013 and October 2014 (18 months). 31 of the 41 patients were resected high risk Dukes B colon cancer patients. 24 of the 31 patients (77%) were under the age of 75 and were considered for adjuvant chemotherapy. 3 of the 24 patients (13%) were found to have dMMR. 2 of the 3 dMMR patients did not proceed to have adjuvant treatment. 13 of the 24 patients (54%), including 1 dMMR patient, were commenced on adjuvant chemotherapy.. 7 of the 31 high risk Dukes B patients (23%) were over the age of 75. None of the over-75 patients were given chemotherapy. 4 of them (57%) were found to have dMMR. All dMMR patients had right sided colon cancer.. The overall prevalence of dMMR in high risk Dukes B patients was 23%. The cost of an MMR protein immunohistochemistry was under £50, whereas a 6 month course of Capecitabine chemotherapy, including all non-drug clinical costs, could amount up to £3500..

Immunocytochemical Expression of BAX and BAK Proteins in Cervical Smears of Women Positive for HPV Types: A Study of 120 Cases
MEDINA BUENO, Gonzalo Arturo. Clinical and prognostic characteristics of the molecular subtypes of breast cancer determined by immunohistochemistry. Arequipa, Peru. Rev. perú. med. exp. salud publica [online]. 2017, vol.34, n.3, pp.472-477. ISSN 1726-4634. http://dx.doi.org/10.17843/rpmesp.2017.343.2530.. The objective of this study was to determine the clinical and prognostic characteristics of breast carcinomas according to the molecular subtype using immunohistochemical markers. The study included 280 women with unilateral breast cancer enrolled from 2009 to 2012. The carcinomas were classified into four subtypes based on immunohistochemical findings: luminal A, luminal B, HER2, and triple negative. The Kaplan-Meier test was used to determine the effect of histological type and molecular subtype on overall survival. Our results indicated that the most common breast carcinoma subtype was luminal A (105 cases, 37.5%), followed by luminal B (88 cases, 31.4%), HER2 (46 cases, 16.4%), and triple ...
The tumor cells were arranged in organoid clusters or sheets and composed of round to polygonal cells with central round nucleus, abundant eosinophilic or clear cytoplasm and distinct cell membrane (IMAGES 1, 2). Myxoid matrix was also present between the tumor cells (IMAGE 3). The tumor had increased cellularity with nuclear pleomorphism and significant mitotic activity (IMAGES 4, 5). Immunohistochemical stains showed an unusual pattern of staining for CD117 (c-kit) (IMAGE 6). Instead of cytoplasmic staining as typically seen in GIST, there was predominantly nuclear staining. CD34 (IMAGE 7), smooth muscle specific actin (IMAGE 8) and S-100 (IMAGE 9) were immunostain negative. Atypical staining for CD117 and absence of positive immunohistochemical staining for CD34 in the present tumor tissue prevent a definitive diagnosis of GIST at this time. Loss of positive staining for these characteristic GIST markers could be consistent with tumor dedifferentiation over time associated with recurrence. ...
Pathological tissue is excised with a beam from a laser that is coupled through a flexible, optical waveguide to a collimator that reduces the beam cross-sectional area by variable, controlled amounts. A transparent bore or a graphite cannule couples the beam exiting the collimator to the tissue to vaporize same. An electrically responsive deflector gyrates the reduced cross-sectional area beam about a bore sight axis aligned with the cannula bore so that the excised tissue has a frusto-conical volume. To excise different, displaced tissue regions, a position servo system moves the cannula so the bore sight axis moves in a plane at right angles to a plane on the exterior surface containing the pathological tissue.
IHC remains the simplest method for detecting biomarker expression while maintaining spatial context within tissues. Getting reliable staining hinges on the specificity of your antibody.

After a further 32 to 36 months in clean air, morphologic examination of lungs by light microscopy, scanning electron microscopy, and transmission electron microscopy revealed two important exposure-related lesions. They were enlargement of air spaces in proximal acinar regions, with and without increases in the number and size of interalveolar pores, and hyperplasia of nonciliated bronchiolar cells. Proximal enlargement of air spaces was most severe, both subjectively and morphometrically, in ...

The 116 DLBCL analyzed in our study were diagnosed according to the histopathological and immunohistochemical characteristics described in the WHO classification and additionally according to novel gene expression features recently defined by our group.10. Forty-three of our 116 cases of DLBCL had a genomic gain of BCL2 and MALT1 and one case revealed an amplification of MALT1 together with a normal BCL2 gene status (together 38%), while 72 cases (62%) had normal copy numbers of the BCL2 and MALT1 genes not considering changes in ploidy. Interestingly, gain of the BCL2 gene was invariably associated with gain of the MALT1 gene in our series. Moreover, the presence of a 18q21/MALT1 gain correlated with upregulation of genes located on 18q including MALT1 at the RNA level, independently of the ABC or GCB gene expression signature, and was strongly associated with over-expression of BCL2 protein. We found a significant accumulation of cases with a 18q21/MALT1 gain among those with an ABC signature ...

Background and aims: The putative stem cell marker CD24 is a small, heavily glycosylated, cell surface molecule which was originally associated with tumour metastasis. Recently it has been reported to be upregulated and of prognostic importance in colorectal tumours. The study aims to study the prognostic value of CD24 in a large series of colorectal cancer (CRC).. Methods: CD24 protein expression was examined by immunohistochemistry. A total of 10 whole tissue sections (WTS) of adenoma and 345 CRCs arranged as tissue microarrays (TMAs) were evaluated. For comparison with non-neoplastic tissue, 10 WTS containing tumour with associated non-neoplastic tissue were also studied.. Results: None of the samples of normal tissue (adjacent to tumour) showed CD24 expression. In the tumours, CD24 expression was seen on the luminal surface of the cells, within the cytoplasm and, unexpectedly, also within the nucleus. Positive immunostaining was seen in 9/10 (90%) adenomas and 313/345 (91%) of CRCs. Weak ...

Antibodies can be generated by injecting animals with antigens, and then collecting serum after the immune response has taken place. If the antibodies are labeled with an easily detectable molecule (a fluorescent dye, an enzyme, etc.), they become powerful detection reagents for the antigen. This system has been exploited to generate exceptionally specific and sensitive stains which are used in histology as well as other disciplines.. Immunohistochemistry/cytology is the use of antibodies in light microscopy and EM. The basic process depends upon selecting an antibody sufficiently specific to bind an antigen in situ. The antibody/antigen conjugate is then identified using a variety of signal generating molecules triggered either by the antibody/antigen interaction or by secondary processes. The signal generators can be precipitating dyes, fluorescent molecules or electron dense (ultrastructural tag) materials for electron microscopy (EM).. The first report of an immunohistochemistry technique ...
Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype with high recurrences and mortality rate, for which no therapies besides chemotherapy are available to date. Lacking specific markers for an effective targeted therapy, TNBCs continue to represent the most important challenge for clinical oncologists. Here, we investigated the expression of CDCP1, a transmembrane non-catalytic receptor reportedly associated with poor prognosis in some solid tumors (e.g., lung and pancreatic cancer), and its association with tumor aggressiveness in a cohort of 115 human TNBC primary specimens obtained from women surgically treated in our Institute from the beginning of 2002 to the end of 2006 and selected based on immunohistochemical (IHC) criteria (,1% cell positivity for estrogen receptor, progesterone receptor and HER2 expression classified as 0 or 1+). CDCP1 was overexpressed in 56.5% of human primary TNBCs. FISH analysis of 75 TNBCs for which material was available delineated four ...
CD24 has been described in B-cell development and B-cell neoplasia, in the developing pancreas and brain, and in regenerating muscle, keratinocytes, renal tubules, and a large variety of malignant tumors (12 , 13 , 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30 , 32, 33, 34) . In this immunohistochemistry-based study we describe the expression of CD24 protein in breast cancer. Basically, we can confirm the findings of Fogel et al. (31) , who were the first to describe CD24 expression of breast cancer in an immunohistochemistry study based on frozen sections. They reported an apical membranous CD24 immunoreactivity in benign ducts and an additional cytoplasmic staining in invasive carcinomas, and described CD24 expression as a marker of breast cancer. We used a commercially available monoclonal CD24 antibody that is applicable to paraffinized tumor tissue and, thus, made a comprehensive analysis of clinically characterized archive material possible. The specificity of the antibody was ...

A common method for studying the involvement of catabolic pathways in the degradation of particular proteins is to pharmacologically inhibit the pathways, and examine-by Western blots or quantitative immunohistochemistry, for example-how these manipulations affect total quantities of the proteins in question. Unfortunately, these methods are incapable of separating the effects of such inhibitors on protein degradation from effects on protein synthesis. These processes are more readily discernible in pulse‐chase experiments based on radioactive amino acids; this approach, however, is not free from confounds either: On the one hand, the slow turnover rates of synaptic proteins require relatively long labeling periods. On the other, labeling is typically associated with substantial (ten‐ to hundredfold) reductions in (labeled) amino acid concentrations, raising the risk of inducing macroautophagy (see, e.g. Sutter et al, 2013). In contrast, the methods used here do not suffer from either of ...
The Central Dogma of biology holds, in famously simplified terms, that DNA makes RNA makes proteins, but there is considerable uncertainty regarding the general, genome-wide correlation between levels of RNA and corresponding proteins. Therefore, to assess degrees of this correlation we compared the RNA profiles (determined using both cDNA- and oligo-based microarrays) and protein profiles (determined immunohistochemically in tissue microarrays) of 1066 gene products in 23 human cell lines. A high mean correlation coefficient (0.52) was obtained from the pairwise comparison of RNA levels determined by the two platforms. Significant correlations, with correlation coefficients exceeding 0.445, between protein and RNA levels were also obtained for a third of the specific gene products. However, the correlation coefficients between levels of RNA and protein products of specific genes varied widely, and the mean correlations between the protein and corresponding RNA levels determined using the cDNA- and

Histological grade of hepatocellular carcinoma (HCC) is an important prognostic factor affecting patient survival. It has been divided into four grades from I to IV on the basis of histological differentiation. Grade I is the best differentiated consisting of small tumor cells arranged in thin trabeculae. Cells with higher grade are larger and less differentiated with hyperchromatic nuclei and loss of trabecular pattern.. Ultrasound is an imaging modality frequently used to evaluate liver tumors because of its convenience, real-time, less expensive and no radiation exposure. However, ultrasonographic evaluation by conventional B-mode image is semi quantitative and subjective. It still cannot replace liver biopsy for the evaluation of HCC..

Purpose: The level of estrogen receptor (ER), progesterone receptor (PR), and HER2 aids in the determination of prognosis and treatment of breast cancer. Immunohistochemistry is currently the predominant method for assessment, but differences in methods and interpretation can substantially affect the accuracy, resulting in misclassification. Here, we investigated the association of microarray-based mRNA expression levels compared with immunohistochemistry.. Experimental Design: Microarray mRNA quantification of ER, PR, and HER2 was done by the developed TargetPrint test and compared with immunohistochemical assessment for breast tumors from 636 patients. Immunohistochemistry was done in a central laboratory and in an independent reference laboratory according to American Society of Clinical Oncology/College of American Pathologists guidelines for 100 cases. For HER2 immunohistochemistry 2+ cases, additional chromogenic in situ hybridization (CISH) was used to determine the final ...
