General description

Colcemid is also known as demecolcine. Its generic name is N-methyl-N-deacetyl-colchicine. Colcemid depolymerizes microtubules and blocks mitosis at metaphase.

Application

Colcemid inhibits the formation of mitotic spindles. It is used to increase the percentage of metaphase cells for chromosome analysis.

Biochem/physiol Actions

Often in karyotyping and cell cycle research it is desirable to increase the yield of mitotic cells in a particular phase of the cell cycle. This can be achieved in a variety of ways with the most popular being the use of a cell cycle synchronizing agent such as demecolcine. Demecolcine will arrest cells in metaphase with no remarkable effect on the biochemical events in mitotic cells or in synchronized G1 and S phase cells. White blood cells are often treated with demecolcine to arrest cells in metaphase.

Physical form

Solution (10 μg/ml), filtered through 0.2 μm pore size membrane.

The human RB1 gene is imprinted due to integration of the PPP1R26P1 pseudogene into intron 2. PPP1R26P1 harbors the gametic differentially methylated region of the RB1 gene, CpG85, which is methylated in the female germ line. The paternally unmethylated CpG85

Phosphorylation of histone H3 threonine 118 (H3 T118ph) weakens histone DNA-contacts, disrupting the nucleosome structure. We show that Aurora-A mediated H3 T118ph occurs at pericentromeres and chromosome arms during prophase and is lost upon chromosome alignment. Expression of H3 T118E

Chromosomal instability (CIN) is a hallmark of many cancers. Restricting the localization of centromeric histone H3 variant CENP-A to centromeres prevents CIN. CENP-A overexpression (OE) and mislocalization have been observed in cancers and correlate with poor prognosis; however, the molecular
