Chromosomal instability in Streptomyces avermitilis: major deletion in the central region and stable circularized chromosome

BMC Microbiology, 2010
Background The chromosome of Streptomyces has been shown to be unstable, frequently undergoing gross chromosomal rearrangements. However, the mechanisms underlying this phenomenon remain unclear, with previous studies focused on two chromosomal ends as ...

Predictive value of aberrant right subclavian artery for fetal chromosome aneuploidy in women of advanced maternal age

BMC Pregnancy and Childbirth, 2021
Background In the entire population, an aberrant right subclavian artery (ARSA) is closely associated with chromosomal abnormalities. ARSA with additional ultrasonic findings would increase risk of chromosomal abnormalities. The risk of fetal chromosomal

Phosphorylation of SU(VAR)3-9 by the chromosomal kinase JIL-1 [PDF]

, 2010
The histone methyltransferase SU(VAR)3-9 plays an important role in the formation of heterochromatin within the eukaryotic nucleus. Several studies have shown that the formation of condensed chromatin is highly regulated during development, suggesting ...
