In this species, a single large nucleolus located eccentrically at the periphery of the nucleoplasm was observed.
Nucleoplasm staining patterns and cell cy-cle-associated expression of Ki-67 in middle ear cholesteatoma.
The nucleoli that were generally arranged to form a regular layer in the nuclear envelope of normal grooving previtellogenic oocytes were distributed irregularly in the nucleoplasm (Fig.
Prominent bundles were clearly visible throughout the cytosol and in the nucleoplasm. In one gadiform species, saithe (Pollachius virens), hemolysis was acute, and intact cellular membranes were not visible (Fig.
Chromatinnucleolus oocytes have a large nucleus and scant basophilic solid ooplasm, whereas the nucleoplasm is granular and characterized by the presence of nucleoli and dispersed chromatin.
In contrast to the NPC central region, eight of the filament-like structures called cytoplasmic filaments extend from the cytoplasmic ring into the cytoplasm, whereas the basket-like structures called the nuclear basket extend from the nuclear ring into the nucleoplasm. Peripheral regions such as cytoplasmic filaments and the nuclear basket consist of asymmetrically arranged nucleoporins.
The nomenclature for nuclear patterns is primarily based on the reactivity observed in the nucleoplasm (for example, homogeneous or speckled) and the nuclear subcomponents that are recognized (for example, centromere or nucleolar).
Visualizing subcellular localization of AltMV TGBp1 variants both functional and defective in terms of oligomerization revealed the following pattern: AltMV TGBp1 variants capable of oligomerization were localized at the nucleolus or at the cell wall, while the mutant ones occupied the nucleoplasm instead of the nucleolus and were not detected in the vicinity of the cell wall [36].
In the cellular component, nucleoplasm (P = 4.95E - 07), spindle microtubule (P = 249 E - 06), and spindle pole (P = 6.09E - 06) were the top three GO terms, and there were 51 DEGs enriched in the nucleoplasm.
Among the intracellular sites for LT synthesis, it is known that 5-LO resides in the cytoplasm or nucleoplasm of resting cells and can translocate to the nuclear membrane upon activation by [Ca.sup.2+], where it colocalizes with [cPLA.sub.2] and FLAP [41].
In addition, GO cell component (CC) analysis also displayed that the downregulated DEGs were significantly enriched in the cytosol, membrane-bounded vesicles, and nucleoplasm (Table 1).
