cen·tri·ole

 (sĕn′trē-ōl′)
n.
One of two cylindrical cellular structures that are composed of nine triplet microtubules and form the asters during mitosis.

[New Latin centriolum, diminutive of Latin centrum, center; see center.]

centriole

(ˈsɛntrɪˌəʊl)
n
(Genetics) either of two rodlike bodies in most animal cells that form the poles of the spindle during mitosis
[C19: from New Latin centriolum, diminutive of Latin centrum centre]

cen•tri•ole

(ˈsɛn triˌoʊl)

n.
a small cylindrical cell organelle, seen near the nucleus in the cytoplasm of most eukaryotic cells, that divides perpendicularly during mitosis.
[< German Zentriol (1895), derivative of Latin centrum center]

cen·tri·ole

(sĕn′trē-ōl′)
Either of a pair of cylinder-shaped bodies found in the centrosome of an animal cell. During mitosis, the centrioles move apart to help form the spindle, which then distributes the chromosomes in the dividing cell. See more at cell, meiosis, mitosis.

centriole

1. Either of two organelles near the nucleus involved in cell division.
2. One of a group of tiny tubules near the nucleus of a cell. Centrioles play a part in cell division. See mitosis.

Nevertheless, because sand dollars (like most marine invertebrates) have external fertilization and no parental care, opportunities for non-genetic paternal contributions to embryonic and larval development are limited to substances or organelles in the sperm itself (such as the centriole) and paternal imprinting {via, e.g., methylation patterns; see, e.g., McBirney et al., 2017), of which there have been no reports to date in echinoids (sand dollars and urchins).
To date, 19 genes (MCPH1-19) have been linked to MCPH (Abdel-Hamid et al., 2016) that encode proteins involved in cell cycle regulation, DNA damage response, centriole duplication, neurogenesis and spindle pole organization and orientation (Bond et al., 2002; Faheem et al., 2015).
Rare patterns were consisted of 49 (0.49%) midbody, 29 (0.29%) centriole, 20 (0.20%) spindle fibers, 21 (0.21%) anti-golgi, 37 (0.37%) anti-actin, 3 (0.03%) rod and rings, and 9 (0.09%) PCNA (proliferating cell nuclear antigen)-like (Table 1).
Centrosomes contain two centrioles, the mother centriole and a younger newly duplicated daughter centriole (Vorobjev & Chentsov 1982, Azimzadeh & Marshall 2010).

In our experiment, it showed that some TFs were related to cell cycle and regulated the genes of cell cycle obviously; for example, ANAPC5, BUB3, and ZBTB20 regulated gene expression of CEP27 The CEP family protein is the active component of centrosome and plays a vital role in centriole biogenesis and cell cycle progression control [36].
