Therefore, the name resting microglia is replaced slowly with surveilling microglia. These may be related to the role played by epithelial-mesenchymal transition EMT and cancer stem cells in endometrial carcinogenesis. In this context, our review highlights the prognostic significance of endometrial cancer microsatellite instability types of myoinvasion in low grade, low stage endometrioid endometrial carcinoma, as a reflection of these molecular changes at the invasive front.

According to recently introduced myoinvasive patterns, the diffusely infiltrating and microcystic, elongated, and fragmented MELF endometrial cancer microsatellite instability show loss of hormone receptors, along with EMT and high expression of cancer stem cell markers, being associated with a poor prognosis.

Additionally, MELF pattern exhibits a high incidence of lymphovascular invasion and lymph node metastases.

AM-like pattern must be differentiated from carcinoma invasion of AM foci, while adenoma malignum pattern creates difficulties in appreciating the depth of myoinvasion and requires differential diagnosis with other conditions. Another pattern expecting its validation and prognostic significance value is the nodular fasciitis-like stroma and large cystic growth pattern.

In practice, the knowledge of these patterns of myoinvasion may be valuable for the correct assessment of stage, may improve prognosis evaluation and may help identify molecules for future targeted therapies. The role of tumor microenvironment in development and progression of malignant melanomas - a systematic review Simona Gurzu, Marius Alexandru Beleaua, Ioan Jung To reveal the particular aspects of the tumor microenvironment of malignant melanomas, a systematic review including 34 representative papers was performed.

The possible reversible features of EMT and the role of tumor microenvironment endometrial cancer microsatellite instability the metastatic process were also analyzed.

  1. Results: There were selected, for these immunohistochemistry reactions, 22 cases of simple hyperplasia without atypia, 26 cases of complex hyperplasia without atypia, 23 cases of endometrial adenocarcinoma of endometrioid type, well differentiated, 22 cases of endometrial adenocarcinoma of endometrioid type, moderately differentiated, and 19 cases of non-endometrioid adenocarcinomas represented by nine clear cells and 10 serous endometrial adenocarcinomas.

As the McSCs embryological development in mouse is not similar to human development, the role of stem cells in genesis and development of human melanoma endometrial cancer microsatellite instability be proved in human melanoma cells only.

For further development of targeted therapy, a better understanding of melanomagenesis pathways and its microenvironment particularities is necessary. Immunohistochemistry predictive markers for primary colorectal cancer tumors: where are we and where are we going? We reviewed articles that examined CRC samples with significant statistic correlation between the IHC marker expression and disease progression over time, relationships with the available clinical features and those who detect the prognosis of drug effects.

Our analysis showed that nine markers could correlate with medical treatment response of CRCs in different stages.

When using better overall survival OS and better disease-free survival DFS as a grouping factor, there were 14 markers that could be used in assessing CRC prognosis. Subgroup analysis was also performed based on the 32 markers recently confirmed to predict metastasis evolution or the recurrence risks. Venous invasion could be predictable for tumors, statistically significant metastasis susceptibility was observed for markers and also the capacity to evaluate recurrence.

CRCs integrate a variety of localizations and there are proofs that distinguish the sites of tumors. The studies reporting data specifically for rectal cancer separating it from colon cancer contained seven IHC markers.

In order to be able to implement a predictive biomarker in clinical practice, it must comply with certain criteria as clinical value and analytical proof. Unique biological signature of CRC can be distinguished by identifying biomarkers expression.

Several markers have shown potential, but the majority still need to render clinical utility. The prostatic cellular and molecular kaleidoscope. Starting points for carcinogenesis Andrei Daniel Timofte, Irina-Draga Caruntu The prostate cancer is a heterogeneous disorder concealing different phenotypical and functional subtypes papilloma virus sintomi donne cancer cells.

This heterogeneity mirrors the normal prostate cell lineages whose alterations represent the starting points of the carcinogenesis mechanism.

The histological structure of the prostate comprises two main types of cells: epithelial and stromal, with a stromal to epithelial ratio of The prostate acini are lined by a contiguous layer composed of four different subtypes of epithelial cells: secretory luminal, basal, neuroendocrine, and transit-amplifying. The epithelial component is enclosed in a stromal tissue, consisting of several types of cells: smooth muscle cells the most numerous cell typefibroblasts, and myofibroblasts.

Despite their quite similar morphological appearance in light microscopy, the molecular markers endometrial cancer microsatellite instability by the normal epithelial and stromal prostatic components, as well as the stem cells show that the prostatic cells are not equal. Consequently, several hypotheses regarding the location and the phenotype of these cells were formulated and tested, mainly in animal models. The molecular mapping of normal human prostate tissue might be the key for unlocking the intricate mechanisms of prostate carcinogenesis.

Within this context, endometrial cancer microsatellite instability prostatic cancer stem cells are thought to play an important role in tumor initiation, progression, recurrence and also therapy resistance. The cancerous phenotype of a stem cell can be reached via multiple genetic trajectories and epigenetic alterations, resulting in different subclonal populations of cancer stem cells, thus explaining the heterogeneity of the prostatic neoplasia.

Future efforts should be directed towards better understanding of the relationship and interactions between these endometrial cancer microsatellite instability stem cells subpopulations, their microenvironments, and also towards characterizing the signaling pathways and molecules involved in the regulation of prostatic cancer stem cells. The results of these studies could offer a different, more comprehensible perspective for a new, molecular classification of prostate cancer, overlapping the existing histological one.

Starting points for carcinogenesis PDF 6. It was revealed that mixing with alloying elements, such as Mn and Zn, provides improved corrosion resistance to Mg alloys; this pursuit is built on the fact that Mg and its alloys are degradable through their time in the human body. Furthermore, Mg alloys afford a characteristic profile that is very close or even almost identical to that of human bone.

Minimizing the rate of corrosion of Mg is the most adequate method, because a low corrosion rate of an Mg implant involves a decrease in the extent of hydrogen evolution and alkalization, which allow the human body to gradually absorb or consume the corrosion products.

In those situations, both clinical and paraclinical findings might orientate the diagnosis, but only histological or immunohistochemistry changes might be accurate enough. The skin histological changes are relevant and sometimes might have a tremendous role in the accurate diagnosis of autoimmune rheumatic diseases, due to the correlation with the clinical systemic manifestations of the diseases and through the accessibility of biopsy.

In the same time, muscle biopsy can provide important support for physicians improving diagnosis and optimizing management of connective tissue diseases. Correlations between morphological changes induced by curcumin and its biological activities Laura Stoica, Bogdan Alexandru Stoica, Doinita Olinici, Pavel Onofrei, Emanuela Ana Botez, Carmen Elena Cotrutz Curcumin is a phytochemical polyphenol extracted from turmeric rhizome, with multiple biological activities, intensively studied in various therapeutic areas.

Its effects covers a wide range of specialties, from the neuroprotective to the antimetastatic properties, influencing pathologies from cardiovascular, neuronal and oncological fields, as a part of its broad spectrum of action. These effects are explained by antioxidant, anti-inflammatory and anticarcinogenic simultaneous roles of endometrial cancer microsatellite instability and its derivatives.
