Centrosomes are crucial in the assembly of mitotic spindles and faithful separation of chromosomes in mitosis. Like chromosomes, centrosomes need to be duplicated exactly once during the cell cycle, suggesting mutual regulation. Clinically, germ line mutations of centrosomal components lead to similar syndromes as defects in the replication stress signaling, a condition termed Seckel syndrome. Our aim is to understand how centrosomal integrity affects DNA replication. Preliminary results indicate ...
Replication stress (RS) and chromosomal instability (CIN) are commonly observed features of cancer cells. RS has a destabilizing effect on the genome and, vice versa, whole chromosome aneuploidy as a result of CIN can induce a RS response. Our preliminary data analysis of cancer genomic data suggests a tendency of whole chromosome CIN (W-CIN) to co-occur with structural CIN (S-CIN), whilst S-CIN can also appear in numerical stable tumors. We also found a significant positive correlation of mRNA ...
