Insensitivity of Chromosome I and the Cell Cycle to Blockage of Replication and Segregation of Vibrio cholerae Chromosome II

mBio, 2012
Vibrio cholerae has two chromosomes (chrI and chrII) whose replication and segregation are under different genetic controls. The region covering the replication origin of chrI resembles that of the Escherichia coli chromosome, and both origins are under ...

Alternating Dynamics of oriC, SMC, and MksBEF in Segregation of Pseudomonas aeruginosa Chromosome

mSphere, 2020
Condensins are essential for global chromosome organization in diverse bacteria. Atypically, the Pseudomonas aeruginosa chromosome encodes condensins from two superfamilies, SMC-ScpAB and MksBEF.

Trypanosoma cruzi expresses a plant-like ascorbate-dependent hemoperoxidase localized to the endoplasmic reticulum.

, 2002
In most aerobic organisms hemoperoxidases play a major role in H(2)O(2)-detoxification, but trypanosomatids have been reported to lack this activity.

Retinitis Pigmentosa‐Associated Gene TRIM49 Regulates ULK1‐Mediated Autophagy and Photoreceptor Phagocytosis by the Retinal Pigment Epithelium

Advanced Science, EarlyView.
Based on next‐generation sequencing data of retinitis pigmentosa (RP) patients and controls, this study identifies TRIM49 as a novel gene for autosomal recessive RP. TRIM49 is specifically expressed in the retinal pigment epithelium (RPE) of human retina.

A Forward Genetics Strategy for High‐Throughput Gene Identification via Precise Image‐Based Phenotyping of an Indexed EMS Mutant Library

Advanced Science, EarlyView.
The GeneHunter‐Gene‐Level Association (GH‐GLA) pipeline enables high‐throughput gene identification in an indexed EMS population of wheat cultivar KN9204. It identifies 5905 trait‐associated wheat genes and validates key regulators of kernel weight and spikelet architecture via gene editing and haplotype analysis.

Axial contraction and short-range compaction of chromatin synergistically promote mitotic chromosome condensation

eLife, 2015
The segregation of eukaryotic chromosomes during mitosis requires their extensive folding into units of manageable size for the mitotic spindle. Here, we report on how phosphorylation at serine 10 of histone H3 (H3 S10) contributes to this process. Using

Identification of a Second‐Hit Brain Somatic DEPDC5 Variant Supports Causality of a DEPDC5 Germline Variant of Uncertain Significance. Time for a Classification Update?

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Germline variants in DEPDC5 are a cause of familial focal epilepsy with variable foci. Affected individuals may have focal cortical dysplasia if a second brain somatic variant occurs. As access to brain tissue is limited, the second somatic hit in the brain is usually presumed if a clear pathogenic germline variant is present. Here, we present

Exonic Variation and Its Clinical Impact in 7221 Old Order Amish

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The Amish of Lancaster County, PA has been the focus of genetic studies for many years due to its demographic history and unique genetic makeup that includes a historical bottleneck event and subsequent genetic drift, resulting in a marked decrease in genetic diversity and increased frequency of some variants that have substantially shaped the

Coupling chromosome organization to genome segregation in Archaea

Nature Communications
Chromosome segregation is a fundamental process in all life forms and requires coordination with genome organization, replication and cell division. The mechanism that mediates chromosome segregation in archaea remains enigmatic.

Case Series of Nizon‐Isidor Syndrome by Heterozygous Variants in MED12L With Further Evidence of Mitotic Instability in One Case With Diploid–Triploid Mosaicism

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nizon‐Isidor syndrome is a rare disorder caused by heterozygous variants in MED12L, with only eight documented cases in the literature. Here, we present three additional cases of this syndrome. Proband 1 was a 7‐year‐old female who presented with developmental delay, right‐leg hemihypertrophy, laryngeal cleft, esotropia, abnormal skin ...
