An ANA test is considered positive if fluorescence is seen at a titre of 1:40/1:80. Higher titres are more clinically significant as low positives (≤1:160) are found in up to 20% of healthy individuals, especially the elderly. Only around 5% of the healthy population have ANA titres of 1:160 or higher. [8] [53]
Immunofluorescence staining pattern of anti-centromere antibodies on HEp-20-10 cells. Anti-centromere antibodies (ACAs; often styled solid, anticentromere) are autoantibodies specific to centromere and kinetochore function.
Humans and mice have three centrin genes: Cetn-1, which is typically only expressed in male germ cells, and Cetn-2 and Cetn-3, which are typically only expressed in somatic cells. Centrin-2 is a recombinant GFP-centrin-2 and centriole protein that localizes to centrioles throughout the cell cycle, while centrin-3 seems to stick to the ...
The mother centriole just aids in the accumulation of materials required for the assembly of the daughter centriole. [17] Centrosome (shown by arrow) next to nucleus. Centrioles, however, are not required for the progression of mitosis. When the centrioles are irradiated by a laser, mitosis proceeds normally with a morphologically normal spindle.

Basal bodies originate from and have a substructure similar to that of centrioles, with nine peripheral microtubule triplets (see structure at bottom center of image). A basal body (synonymous with basal granule , kinetosome , and in older cytological literature with blepharoplast ) is a protein structure found at the base of a eukaryotic ...
The four teams that played in the Week 16 Saturday games will suit up again on the holiday, starting with the Pittsburgh Steelers hosting the Kansas City Chiefs starting at 1 p.m. ET.
