Cav1 has also been localized to the nucleus of ovarian carcinoma cells where it binds directly to promoter regions of the cyclin D1 and folate receptor genes. (diff.org)

Surgical aspects of subungual malignant melanomas. (wheelessonline.com)
Histopathologic study of the surgical piece revealed a malignant mesenchymal tumor of high cellular density arrayed in sheets and adopting different patterns in which fusiform, epithelioid, highly collagenized, and myxoid areas alternated. (isciii.es)

While epithelioid is consistently the most prevalent histologic subtype of MPM, the relative incidence of each subtype varies by study population and by specimen type. (atlasgeneticsoncology.org)

The cell size can vary from small (basal cells) to very large (squamous epithelial cells). (vin.com)
Some Cav1 has been localized, in a cell type-specific manner, to the cytosol (for example in skeletal muscle cells and keratinocytes), secretory vesicles (in endocrine and exocrine cells), mitochondria (in airway epithelial cells) and lipid droplets. (diff.org)

Epithelioid cells are associated with more aggressive behavior and carry a poorer prognosis for the patient's survival. (medscape.com)
The large cell carcinoma class has been enriched with several variants, including the LCNEC and the basaloid carcinoma, both with a dismal prognosis. (ersjournals.com)

Dendritic cells (DCs) are essential for the development of asthma via presenting allergens, causing Th2 skewing and eosinophil inflammation. (nagoya-u.ac.jp)

Nonmesotheliomatous cancers of the pleura include an assortment of malignant neoplasms that primarily or secondarily involve pleura. (medscape.com)

All cases demonstrated malignant tumor characteristics including diffuse 270 to 360-degree ciliary body ring growth pattern, epithelioid-cell type and presence of either BAP-1 expression loss or gain of MYC gene. (bvsalud.org)

Immunohistochemistry showed that the epithelioid cells were positive for CD34. (biomedcentral.com)
Immunohistochemistry showed tumor cells with extensive and diffuse positivity to muscular actin (HHF 35) and negativity to desmin and osteocalcin. (isciii.es)

However, malignant SFTs, which comprise 10%-15% of SFTs, not only aggressively infiltrate adjacent structures but are also capable of metastatic spread. (medscape.com)

JCT is morphologically characterized by multiple foci malignant mesenchymal epithelioid cells with, often with admixed necrosis, and a perivascular growth pattern. (wikipedia.org)

Methods: 37 antibodies detecting proteins engaged in cell signalling pathways, enforcing proliferation, anti-apoptosis, angiogenesis and other cellular activities were investigated by tissue microarray (TMA) technology. (houstonmethodist.org)
Comparing HESC controls with HESCs deficient in SRC-3, gene enrichment analysis of the differentially expressed gene set revealed an overrepresentation of genes involved in chromatin remodeling, cell proliferation/motility, and programmed cell death. (frontiersin.org)

GISTs start in specialized nerve cells located in the walls of your digestive system. (suratoncologycentre.in)

After about 20-50 years, these fibers can cause inflammation and mutations in healthy cells. (survivingmesothelioma.com)
Because the cytological characteristics of hyperplasia, inflammation, and malignancy can differ in different tissues, it is important to first determine the most frequently occurring type of cell in the cytological preparation. (vin.com)

More cancer-directed surgeries and better identification of cell types in MPM patients may be behind the improved survival rates. (survivingmesothelioma.com)

Asbestos causes genetic modifications and cell signalling events that favour the resistance of MPM to apoptosis and chemotherapy. (houstonmethodist.org)

The principle contrast between the harmless and the malignant structure is that the previous doesn't spread to different tissues. (webhubdirectory.com)
Cav2 is able to form a stable hetero-oligomeric complex with Cav1 but is not essential for caveolae biogenesis, while Cav3 is primarily located in muscle tissues but is also expressed in glial cells and it plays an essential role in caveolae biogenesis in those tissues where it is expressed.
