Gene Expression in
Leishmania tropica, a unicellular eukaryotic parasite present in North and East Africa, the Middle East, and the Indian subcontinent, has been linked to large outbreaks of cutaneous leishmaniasis in displaced populations in Iraq, Jordan, and Syria. Here,

Compensation of gene dosage on the mammalian X.
Changes in gene dosage can have tremendous evolutionary potential (e.g. whole-genome duplications), but without compensatory mechanisms, they can also lead to gene dysregulation and pathologies.

Effects of gene dosage on cognitive ability: A function-based association study across brain and non-brain processes [PDF]
Summary: Copy-number variants (CNVs) that increase the risk for neurodevelopmental disorders also affect cognitive ability. However, such CNVs remain challenging to study due to their scarcity, limiting our understanding of gene-dosage-sensitive ...

Brain region and gene dosage-differential transcriptomic changes in Shank2-mutant mice [PDF]
Shank2 is an abundant excitatory postsynaptic scaffolding protein that has been implicated in various neurodevelopmental and psychiatric disorders, including autism spectrum disorder (ASD), intellectual disability, attention-deficit/hyperactivity ...

Transient protein-protein interactions perturb E. coli metabolome and cause gene dosage toxicity
Several genes exhibit gene dosage toxicity yet its molecular underpinnings remain unknown. Here we demonstrate that overexpression of DHFR in E. coli causes toxic metabolic imbalance triggered by interactions with several enzymes involved in 1-carbon ...

Single cell transcriptome in aneuploidies reveals mechanisms of gene dosage imbalance
Gene dosage anomalies such as those caused by aneuploidy underlie diseases including Down syndrome. Here, the authors perform allele-specific single cell transcriptome analysis to investigate the mechanisms of gene dosage imbalance in fibroblasts with ...

Sex-chromosome dosage effects on gene expression in humans [PDF]
Significance Sex-chromosome dosage (SCD) effects on human gene expression are central to the biology of sex differences and sex-chromosome aneuploidy syndromes but are challenging to study given the cosegregation of SCD and gonadal status.

Gene dosage compensation: Origins, criteria to identify compensated genes, and mechanisms including sensor loops as an emerging systems‐level property in cancer [PDF]
The gene dosage compensation hypothesis presents a mechanism through which the expression of certain genes is modulated to compensate for differences in the dose of genes when additional chromosomes are present.

IncreasedRrm2gene dosage reduces fragile site breakage and prolongs survival of ATR mutant mice [PDF]
In S. cerevisiae, deletion of the checkpoint kinase Mec1 (ATR) is viable upon mutations that increase the activity of the ribonucleotide reductase (RNR) complex. Lopez-Contreras et al.
