Une mise à jour sur les marqueurs génétiques immunohistochimiques et moléculaires de certaines tumeurs des tissus mous

 

Current years have introduced an immense improve of data concerning the molecular genetic background of mesenchymal tumors which in flip has considerably expanded the repertoire of molecular markers obtainable for the routine diagnostic apply. This progress has additionally been adopted by a rising variety of obtainable immunohistochemical markers helpful for the analysis of soppy tissue neoplasia. Each lineage particular and tumor-specific immunohistochemical antibodies have been found and subsequently examined within the surgical pathology apply.

This text will evaluate among the immunohistochemical and molecular genetic markers helpful within the analysis of vascular tumors, malignant peripheral nerve sheath tumors, low-grade fibromyxoid sarcomas/sclerosing epithelioid fibrosarcomas, solitary fibrous tumors, epithelioid sarcomas, rhabdomyosarcomas and different lesions displaying skeletal muscle differentiation. The immunohistochemical and molecular genetic options of some not too long ago characterised and clinically significantly necessary entities will likely be mentioned as properly.

Les changements transcriptionnels dans la rhinosinusite chronique avec asthme favorisent un endotype moléculaire de kind 2 indépendant du statut polype 

Background: Information concerning the inflammatory profile of sufferers with bronchial asthma and persistent rhinosinusitis (CRS-A) with (CRSwNP-A) and with out (CRSsNP-A) nasal polyposis stay restricted.

Goal: Outline and evaluate systemic transcriptional modifications in sufferers with CRS-A to these with non-asthma-related CRS with (CRSwNP) and with out nasal polyposis (CRSsNP).

Strategies: Thirty-four sufferers with CRS-A (n=19) and CRS (n=15) had been prospectively enrolled into an observational examine. Demographic data and subjective and goal illness severity measures had been recorded. Multiplex gene expression evaluation of mRNA extracted from peripheral blood was carried out. A complete of 594 genes related to innate/adaptive immunity had been analyzed utilizing NanoString expertise. Gene expression ratios had been reported for genes that had been differentially expressed amongst these cohorts. Linear regression evaluation was used to evaluate the mRNA transcript copy numbers for every gene with illness severity.

Outcomes: There was no vital distinction in age, gender, nasal polyposis, or health-related high quality of life measures between the 2 teams (p>0.05). HLA class II histocompatibility antigen, DRB3-1 beta chain (HLA-DRB3) was considerably upregulated within the peripheral blood of sufferers with CRSsNP-A in comparison with CRSsNP, whereas chemokine (C-C motif) ligands 4 (CCL4) and zinc finger protein helios (IKZF2) had been considerably upregulated in CRSwNP-A in comparison with CRSwNP (p<0.05).

Conclusion: Sufferers with CRSsNP-A display a molecular endotype related to a Th2-dominant inflammatory profile in comparison with CRSsNP. Sufferers with CRSwNP-A equally display an overrepresentation of genes related to Th2-driven irritation in comparison with sufferers with CRSwNP.

Caractérisation moléculaire de la blastocystie chez les primates du Nouveau Monde en captivité et en liberté, Platyrrhini 

Objective: Blastocystis species are extensively distributed micro-eukaryote parasites present in each human and nonhuman primates. Regardless of having a worldwide distribution, descriptions of Blastocystis subtype range in neotropical primates is largely restricted to captive animals. The purpose of this examine was to molecularly characterize the presence of Blastocystis in free-ranging black-headed evening monkeys, Aotus nigriceps, and to investigate Blastocystis heterogeneity in primates of the Parvorder Platyrrhini.

Strategies: We analyzed Blastocystis small sub-unit ribosomal DNA (SSUrDNA) from each A. nigriceps and Azara’s evening monkey, A. azarae boliviensis, in Southeastern Peru. We additionally included extra Blastocystis sequence from different neotropical primate research to discover the distribution and host specificity of Blastocystis subtypes (ST) all through the neotropics.

Outcomes: 13 p.c of A. nigriceps samples had been Blastocystis optimistic. Solely ST8 was amplified in A. nigriceps and this partial DNA sequence was extremely just like ST8 sequence beforehand obtained from a human in Brazil. In our evaluation of all obtainable Blastocystis SSU sequences from primates of the Parvorder Platyrrhini, we discovered 15 monophyletic lineages comparable to beforehand described subtypes ST1-ST10, ST12-15, and ST17.

Conclusions: Blastocystis SSU sequences amplified from A. nigriceps fecal samples shared excessive sequence similarity to isolates discovered in a number of different neotropical primates, Alouatta palliata, A. caraya, Ateles fusciceps, and Lagothrix. Related subtypes have been present in human and captive primates which helps the opportunity of transmission when in shut contact. Expanded sampling of sympatric neotropical primates within the wild will set up whether or not subtypes and clades are restricted to taxonomic group or whether or not transmission happens between overlapping species.

Commencement du gliome, classification des caractéristiques moléculaires et caractérisation microstructurale à l’aide de l’imagerie par décomposition de la variance par diffusion (DIVIDE) RM 

Goal: To judge the potential of diffusional variance decomposition (DIVIDE) for grading, molecular function classification, and microstructural characterization of gliomas.

Supplies and strategies: Members with suspected gliomas underwent DIVIDE imaging, yielding parameter maps of fractional anisotropy (FA), imply diffusivity (MD), anisotropic imply kurtosis (MKA), isotropic imply kurtosis (MKI), complete imply kurtosis (MKT), MKA/MKT, and microscopic fractional anisotropy (μFA). Tumor kind and grade, isocitrate dehydrogenase (IDH) half mutant standing, and the Ki-67 labeling index (Ki-67 LI) had been decided after surgical procedure. Statistical evaluation included 33 high-grade gliomas (HGG) and 17 low-grade gliomas (LGG). Tumor diffusion metrics had been in contrast between HGG and LGG, amongst grades, and between wild and mutated IDH varieties utilizing applicable checks in keeping with normality evaluation outcomes. Receiver working attribute and Spearman correlation evaluation had been additionally used for statistical evaluations.

Outcomes: FA, MD, MKA, MKI, MKT, μFA, and MKA/MKT differed between HGG and LGG (FA: p = 0.047; MD: p = 0.037, others p < 0.001), and amongst glioma grade II, III, and IV (FA: p = 0.048; MD: p = 0.038, others p < 0.001). All diffusion metrics differed between wild-type and mutated IDH tumors (MKI: p = 0.003; others: p < 0.001). The metrics that finest discriminated between HGG and LGGs and between wild-type and mutated IDH tumors had been MKT and FA respectively (space beneath the curve 0.866 and 0.881). All diffusion metrics besides FA confirmed vital correlation with Ki-67 LI, and MKI had the best correlation coefficient (rs = 0.618).

Conclusion: DIVIDE is a promising approach for glioma characterization and analysis.
