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.. The other 10 ...
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.

AU - Dungworth, D.. AU - Tyler, W.. AU - Carter, R.. AU - Lum, H.. PY - 1978. Y1 - 1978. N2 - Beagle dogs (104) comprising one control and seven treatment groups were exposed 16 hours daily for 68 months to filtered air, raw or photochemically reacted auto exhaust, oxides of sulfur or nitrogen, or their combinations. 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 ...

HA-tagged proteins can be immunolocalised but only if they are horrifically overexpressed in COS or 293 cells for example. A reasonable level of expression will not be visible above the high background. It is of course possible that we have received poor lots of mAb!

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 ...

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 ...

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 ...

Background: There is limited information on changes in PD-L1 expression levels over time in melanoma.. Methods: PD-L1 expression was measured in melanoma tumor samples collected at different time points from the same patient using a prototype immunohistochemistry (IHC) assay with the 22C3 antibody. PD-L1 positivity was defined as staining in ≥1% of cells. The concordance of PD-L1 expression in paired samples was analyzed by treating the IHC proportion score as a continuous variable or classifying staining as positive or negative.. Results: 48 patients were included. Median age was 65 years (range, 23-85), 73% were male, and 60% had stage I-IIIA disease. All first samples and 85% of second samples were surgical samples. The median interval between sample collection dates was 25.3 months (range, 3.1-203.5). There was no statistically significant correlation of the PD-L1 IHC proportional score between paired samples (Pearson correlation coefficient, 0.13). 40% of patients had an increased ...

Potassium channels are key determinants of neuronal excitability. We recently identified KChIPs as a family of calcium binding proteins that coassociate and colocalize with Kv4 family potassium channels in mammalian brain (An et al. [2000] Nature 403:553). Here, we used light microscopic immunohistochemistry and multilabel immunofluorescence labeling, together with transmission electron microscopic immunohistochemistry, to examine the subcellular distribution of KChIPs and Kv4 channels in adult rat cerebellum. Light microscopic immunohistochemistry was performed on 40-μm free-floating sections using a diaminobenzidine labeling procedure. Multilabel immunofluorescence staining was performed on free-floating sections and on 1-μm ultrathin cryosections. Electron microscopic immunohistochemistry was performed using an immunoperoxidase pre-embedding labeling procedure. By light microscopy, immunoperoxidase labeling showed that Kv4.2, Kv4.3, and KChIPs 1, 3, and 4 (but not KChIP2) were expressed at ...

Hyperactivation of the canonical Wnt/β-catenin pathway, caused by mutations in such components as β-catenin and APC, is one of the most frequent signaling abnormalities in several human cancers including colorectal carcinomas (15), melanomas (16), hepatoblastomas (17), medulloblastomas (18), prostatic carcinomas (19), and uterine and ovarian endometrioid adenocarcinomas (10, 20-22). In breast cancer, however, evidence of comparable mutations is surprisingly lacking (23). In contrast, there is strong evidence, based on immunohistochemical analyses, that the Wnt/β-catenin pathway is activated (23-25). Importantly, aberrant β-catenin expression in breast cancer is associated with poor clinical outcome (23-26). Metaplastic carcinomas have never been analyzed for Wnt pathway gene mutations.. Because breast carcinoma arises from glandular epithelium, it usually exhibits the features of an adenocarcinoma. However, in some cases, part or all of the neoplastic cells differentiate into a nonglandular ...

This studys initial objective was to assess pancreatic β-cell numbers and physiology during immune-mediated islet destruction by following the insulin-positive-to-glucagon-positive cell ratios and other parameters made possible by advanced flow cytometry techniques. We were surprised to observe that the relative frequency of the two endocrine subsets consistently pointed to an unexpected depletion of α-cells, along with the expected β-cell loss at diabetes onset. It is important to point out that because the flow technique lacks an internal reference standard, one cannot accurately determine the absolute number of α- or β-cells in the pancreas, only their relative proportion. We therefore turned to immunofluorescence microscopy and quantitative immunohistochemistry, supported by qRT-PCR, to provide additional, overlapping, and independent techniques. As discussed in our results, all studies supported our initial conclusion that while β-cells are being depleted during autoimmune diabetes, ...
Previous immunohistochemical studies targeting the receptor tyrosine kinase (c-Kit) have demonstrated an apparent reduction in the number of gastrointestinal pacemaker cells--the interstitial cells of Cajal (ICC)--in horses with intestinal motility disorders. This study compared the level of transcription of the c-kit gene encoding this receptor in horses with and without such motility disorders. Transcription levels of this gene were also compared to the density of ICC immunohistochemically positive for the c-Kit antigen. Intestinal samples were collected from 18 horses with intestinal disease and from 15 control animals. Following gene extraction and identification, real-time quantitative analysis of c-kit and a control gene, ACTB (β-actin), was carried out on all samples and the density of the c-Kit-positive ICC compared. There was a significant reduction in c-Kit immunoreactivity in the ICC of horses with large intestinal obstructive disorders relative to controls but no significant ...
Rhcg has a complex subcellular localization. Studies in the human, rat, and mouse kidney demonstrate that Rhcg-expressing cells exhibit both apical and basolateral Rhcg immunoreactivity, with the exception of the non-A, non-B intercalated cell, which has only apical Rhcg (17, 41, 53, 90, 91). Immunogold electron microscopy in both the rat and mouse kidney demonstrated that apical Rhcg is present in both the apical plasma membrane and subapical vesicles and that basolateral Rhcg is present in the basolateral plasma membrane (53, 91). Basolateral expression can be substantial; in the rat OMCD in the inner stripe, basolateral Rhcg is ∼25% of total cellular expression in intercalated cells and ∼40% in principal cells (91). Although initial studies in both the rat and mouse kidney did not identify basolateral Rhcg expression, more recent studies using improved immunohistochemistry techniques and a panel of anti-Rhcg antibodies confirmed basolateral Rhcg expression and demonstrated substantial ...

The expression of the locomotor rhythm requires an intrinsic excitatory drive from interneurons within the locomotor circuits (Grillner, 2003; Roberts et al., 2008; Grillner and Jessell, 2009). However, the molecular identity of the interneurons sufficient to initiate the rhythmic activity of these circuits is still unclear. We used optogenetics to selectively activate a molecularly defined class of interneurons. Our results show that light activation of V2a interneurons selectively expressing ChR2 is sufficient to generate locomotor activity in zebrafish. The selective expression of ChR2 in V2a interneurons was determined immunohistochemically, morphologically, and electrophysiologically. Light stimulation induced a ChR2-induced current, resulting in activation of these interneurons followed by synaptic responses arising from activation of neighboring interneurons. Optogenetic stimulation of V2a interneurons in spinalized preparations was sufficient to induce rhythmic swimming activity ...
The SDH gene is located inside the mitochondria of the cell. It is instrumental in converting nutrients to the energy needed by the body. A deficiency of the SDH enzyme results in an accumulation of succinate during the energy conversion cycle. A build-up of succinate causes aberrant build-up of hypoxia-inducible factor (HIF), a situation referred to as pseudohypoxia. The downstream consequences include an accumulation of the growth factors VEGF and EGFR, leading to the oncogenic problem. SDH-deficiency can be likened to having broken brakes on a car.. Wildtype GIST Clinic patients fall into three categories.. 1. The first group classification stains SDH-positive on immunohistochemistry (SDH IHC+), meaning that the SDH protein is present. Tumor samples of the patients in this group present with a mixed cell histology, meaning that there is a lot of variation in the look of the cells. The primary tumors can originate in the stomach, the duodenum, or the intestine. These patients tend to be ...

Hi. Coming to the histonet for help again. One of my pathologists (Neal Goldstein, MD), will be presenting at the NSH S/C in Rhode Island at the Saturday Plenary Session on Immunohistochemistry, hosted by the Soc. of Applied IHC. He would like to gear his talk on Antigen Preservation in Unstained Tissue Sections towards the people who will be attending. He is talking about QC/QA of antigen preservation. Ive answered his questions the best I can to help him, but there are a couple that have me stumped. PLEASE RESPOND DIRECTLY TO ME, NOT HISTONET. Ill give a summary to histonet. [email protected] 1. What methods are being used by what percent of users for staining IHC? Dr. Goldstein would like to know what percent of people/labs are using: A. Vantana autostainer B. Dako or Biogenex autostainer C. Kits D. home made system (e.g. conc. primary and secondary that the lab titers out) (Im assuming C & D are staining by hand.) Does any Technical rep happen to know? Even a gut level feeling ...

Results. Serum levels of cell-free DNA, myeloperoxidase (MPO)-DNA complex, and α-defensin were significantly increased in patients with AOSD compared to HC. Serum levels of the NET molecules, cell-free DNA, MPO-DNA, and α-defensin were correlated with several disease activity markers for AOSD. In followup of patients with AOSD after treatment with corticosteroid, the levels of cell-free DNA and α-defensin decreased significantly. On immunohistochemistry, neutrophil elastase-positive and MPO-positive inflammatory cells were detected in skin and LN of patients with AOSD, and were expressed in fiber form in the lesions. The serum from patients with active AOSD induced NETosis in neutrophils from HC. NET molecules induced interleukin 1β production in monocytes, representing a novel mechanism in the pathogenesis of AOSD. ...
DFA testing is an immunohistochemistry technique that uses a specific antibody to identify the presence of viral antigens. The antibody is tagged with fluorescent agent and forms an antigen-antibody complex with HSV antigens present within a tissue or smear specimen. The process can be performed with cytologic preparations, such as the Tzanck smear, as well as virally inoculated cell cultures. In addition, DFA may be employed to serotype the HSV infection. Because DFA testing is rapid, sensitive, inexpensive, and virally selective, it often is used to substantiate clinical suspicion and determine serotype.. A punch, shave, or wedge tissue biopsy also may be used to detect the presence of HSV infection and is especially helpful when a suspicious lesion is old or atypical. The biopsied cells are observed microscopically to detect degenerative cytopathologic changes commonly associated with the infection. The degenerative changes present in cells infected with HSV1 and HSV2 also are observed in ...
Immune checkpoint inhibitor (ICI) treatment has recently become a first-line therapy for many non-small cell lung cancer (NSCLC) patients. Unfortunately, most NSCLC patients are refractory to ICI monotherapy, and initial attempts to address this issue with secondary therapeutics have proven unsuccessful. To identify entities precluding CD8+ T cell accumulation in this process, we performed unbiased analyses on flow cytometry, gene expression, and multiplexed immunohistochemical data from a NSCLC patient cohort. The results revealed the presence of a myeloid-rich subgroup, which was devoid of CD4+ and CD8+ T cells. Of all myeloid cell types assessed, neutrophils were the most highly associated with the myeloid phenotype. Additionally, the ratio of CD8+ T cells to neutrophils (CD8/PMN) within the tumor mass optimally distinguished between active and myeloid cases. This ratio was also capable of showing the separation of patients responsive to ICI therapy from those with stable or progressive ...
